natural preservatives

[List] Natural Preservatives for cosmetics

Two days ago, I received an email from a potential client who wanted to hire me for an "intimate parts" product.

We scheduled a phone call to further discuss the project. During our phone conversation, I found out that this client wished to add probiotics to the product . 

My first comment was:

"There's no way probiotics can survive in presence of the preservative".

This is what that prospective client replied: "DON'T ADD THE PRESERVATIVE, THEN. "

There's a new horrible trend going on. It feeds itself on the (false ) belief that everything that is natural is good and vice versa. As a consequence, some brands started making and selling "preservative free cosmetics".

According to some people, preservatives are not necessary and can be even harmful. 

It's true that a high number of skin allergies and reactions are caused by preservatives and fragrances, but...this is not a valid reason to avoid using them.

What you can and should do is to inform yourself about the preservatives that are less likely to cause bad skin reactions. 

Want all natural products?

I get that.

But, even natural products should be safe and include a preservative! Just because you don't see any sign of spoilage, it doesn't mean it's not here. We know cosmetics don't have to be sterile. It would be quite ridiculous. At the same time, you don't want an excessive number of bacteria in them and no pathogen ones at all. Sure, not all bacteria, fungi, and mold are dangerous; however, even the innocuous ones could prevent the product from working the way it is supposed to.

As brand owner, you have the legal and moral responsibility of making sure the products you sell are safe. Period.

Myth #1: is glycerin a preservative?

Every now and then someone asks " is vegetable glycerin a preservative" ?

The question probably arises from the fact that products with a high concentration of glycerin usually don't require a preservative; BUT the glycerin has to be at least 50% which makes the products too sticky.

Furthermore, if you read some DIY blogs, you'll see that some other ingredients are labelled as preservative, yet they're not. To be precise, some might have antimicrobial properties , yet in most cases they're not enough to fully protect a water based product from spoilage. 

Let's see what these supposed "natural preservatives" are: 

  • Vitamin E is not a preservative. It's an antioxidant. 
  •  Essential oils are not ,generally speaking, enough to preserve a product from fungi, bacteria, and mold; however, it's absolutely true that essential oils have anti bacterial properties. The main issue with essential oils is that they tend to have a high affinity for the oil phase of an emulsion, thus limiting their accessibility to the water phase. Furthermore, they might be active against some bacteria , but totally ineffective against other strands. For example, it is well known that Tea Tree oil is not effective against Pseudomonas Aeruginosa. For this reason, if you do attempt to use them as preservative, make sure you use a blend or different oils rather than a single one.  Finally, other ingredients might interfere with their action; before you sell products with essential oils as preservative, make sure you perform the preservative challenge test. 

"Omnia venenum sunt: nec sine veneno quicquam existit. Dosis sola facit, ut venenum non fit" (Paracelsus)

As the wise Paracelsus figured out many years ago, the dose plays a crucial role as well; to exert their function as preservatives, essential oils should be present as combination and at high doses (sometimes more that 3%). These high doses are extremely irritant for the skin; this is why essential oils cannot be used as preservatives.

Are there cosmetics that don't require a preservative?


Products with no water don't need a preservative; however, if you suppose they'll come in contact with water during use, then a preservative will still be necessary.

For examples, oils mixtures do not require a preservative as there's no chance bacteria are going to grow in them without water. From a stability point of view, though, oils still need something able to preserve their good qualities over time...they need an antioxidant.

Fats are well known to become rancid without a good antioxidant. 

Vitamin E is a popular and effective antioxidant. But let's talk about vitamin e as doesn't work! 

To summarize, vitamin E does help to preserve a product, but from a physical stability point of view only. It is not able to kill or prevent bacteria growth.

Other products that don't require a preservative are those with pH values below 4 or above 8 and products with a high content of alcohol (perfumes), salt, or sugar.

Lotions always need a preservative system especially when the water phase is external.

Here's your ultimate list of natural preservatives for cosmetics 


Bacteria, mold, and fungi can easily spread in a preservative free lotion.

As stated above, you should always add a preservative no matter if you want to keep your product 100% natural.

The good news is that there are many different all natural preservatives for cosmetics. Don't listen to whoever says natural preservatives don't work very well. I've formulated many lotions with all natural preservatives, and they all passed microbiological tests.

These preservatives can be used for skincare or haircare.

This list that also includes  organic & Ecocert approved preservatives. I keep the list updated with only products that I have personally tested and samples passed the challenge test.

Please feel free leave a comment with other natural preservatives options.

  • Benzyl Alcohol. Produced by plants, it has a pleasant odor and can be found in some essential oils ,too. It is considered a safe ingredient and helps dealing with Gram+ (Staphylococcus Aerus), Gram- (such as E.Coli, and Pseudomonas Aeruginosa), fungi, and yeast. Did I say pleasant odor? It looks like it is pleasant only for me as every time I ship a sample that contains it people claim they don't like the smell. Give it a try.
  • Dehydroacetic acid: a broad spectrum preservative suitable for Eco-label cosmetics. Can be used alone or in association with another preservative, for example Benzyl Alcohol. There are products that incorporate both Dehydroacetic acid and Benzyl Alcohol, for instance Geogard 221. Dehydroacetic acid has a pH dependent action; works best with pH below 6. It is also a very good anti-fungicide. Other acids effective as preservatives are sorbic and benzoic acid.
  • Glyceryl Caprilate with activity vs bacteria and yeast. It is Ecocert/Cosmos approved and works in a wide pH range (4 to 8).
  • Potassium sorbate is a natural preservative for cosmetics and food. It can be used in a wide variety of products including makeup, skin care products, hair care products, bath products, nail polish, fragrances, oral care products, spermicides, and insect repellants. It is highly soluble in cold water and works best at pH below 6.
  • Caprylhydroxamic Acid (and) Caprylyl Glycol (and) Glycerin (Spectrastat- Inolex). It's a  complete system for "preservative-free" claims cosmetics. It uses multifunctional agents that have excellent efficacy as biostatic and fungistatic agents.  It performs superbly at neutral pH and is compatible with most cosmetic ingredients. However, it can interact with residual iron found in some clay-type compounds (e.g., bentonite, silicates, etc). This interaction with iron may produce a very mild orange color or color.  It may be added to the water phase, at ambient or hot temperatures.  Lengthy exposure to elevated temperatures should be avoided. Typical use level is 0.7% w/w to 1.2% w/w.
  • Geogard ECT ( Benzyl Alcohol & Salicylic Acid & Glycerin & Sorbic Acid) is a natural broad spectrum Ecocert approved preservative. It's very common among natural products , especially in acid exfoliants due to the presence of salicylic acid which has a double effect (it acts as both exfoliating agent and preservative). The producer states Geogard ECT is water soluble, and it definitely is; however I've noticed solutions don't turn out completely clear. I recommend using it at 1%. Geogard preservative is active in a wide range oh pH (3 to 8). It is sometimes referred as Preservative Eco.
  • Sensicare M4200 or Geogard Ultra (Gluconolactone & Sodium Benzoate) is a water soluble broad spectrum preservative that also improves the moisture content. It is widely used in makeup , especially pressed powders. It is compatible with the most common ingredients including cationic, anionic and non-ionic surfactants. It's stable over a wide pH range from 3 to 7 and at high temperatures. It can be added to the water phase at room temperature as well as at higher temperatures. Use it at a % between 1 and 2 in both leave on and rise off products. It complies with  Ecocert/COSMOS standards for preservatives.
  • Anisic acid is a compound with anti-fungal activity only; therefore, it needs to be associated with other preservatives that have anti bacterial activity. Trade name for this molecule is Dermosoft 688 by Evonik Dr. Straetmans GmbH. Smaller amounts for can be purchased from Essential Wholesale Website. The acid form is a bit tricky to dissolve in increase water solubility, you can use the sodium salt instead.
  • Glyceryl Caprylate (and) Glyceryl Undecylenate: this is a recent preservative system that is quickly gaining popularity. It's present in a large number of natural products probably because it's versatile and effective. The composition has also emollient, co-emulsifier, and skin re-fatting properties. It may be incorporated in the oil or water phase at any point during the emulsification process. For optimal results make sure the final formulation has a pH of  5.5 or lower. Trade name is Lexgard Natural by Inolex. Small amounts can be purchased here.
  • Naticide: with an appealing INCI name of "parfum" this preservative is perfect for whoever doesn't want to list a preservative in the actual ingredients list, supporting the "preservative-free claim".  Naticide has wide spectrum of activity, being effective against Gram+, Gram-, yeasts and moulds in a pH range between 4 - 9.  Naticide has also the COSMOS certification.  Buy it from AmazonAccording to Sinerga , the Italian company that makes Naticide, it should be used at 1% . Furthermore, it should be equally divided in the 2 phases (0.5% in the oil phase and 0.5% in the water phase). If using this Ecocert approved natural preservative, you'll have to list it as fragrance in the ingredients list.
  • Ethyl Lauroyl Arginate: this is a food grade surfactant that also has antimicrobial properties. It can be the perfect natural preservative for hair products as it  exhibits good activity against Malassezia Furfur which is responsible for dandruff. Furthermore, it shows good activity against Propioninbacterium Acnes which, as you can guess, is responsible for acne. This preservative is not skin sensitizing or irritating. ELA shows activity between pH 3 and 7 against bacteria, mold, and fungi.
  • Biosecur is a 100% natural preservative made from citrus extract.It's Ecocert certified and USDA organic. Therefore, it's a great option for organic lotions. It's distributed by Sharon worldwide. More information available here.

This is my favorite natural preservative (if something like favorite preservative exists ?).

MINASOLVE GREEN B (more info here). Ecocert/Cosmos Approved. INCI: Pentylene glycol (and) Water (and) Sodium benzoate (and) Benzoic acid. Recommended use level : from 1% to 3%. Works best at pH below 6. 

Don't get me wrong, though. There's no such thing as a "best natural preservative". You need to base your choice on the overall formulation, cost, and availability.

Formulating with natural preservatives like a pro: guidelines and tips.

I don't know how familiar you are with preservatives, but I am pretty sure you know that there's tons of them out there. 

How to choose the right one (or the right combination)? 

  • check
    Rule #1: pick a preservative among those in the Annex V of the EU cosmetic legislation (regularly updated). Remember, when it comes to cosmetic regulations always take Europe as a reference. The cosmetic industry is highly regulated over there and ingredients are "approved" based on their safety profile. Maximum allowable amounts for a single preservative are also listed. You can find the Annex with the list here. For example , the above mentioned Benzyl Alcohol is allowed at 1% maximum. 

When it comes to cosmetic regulations, always take EU as a reference.

  • check
    Rule #2: Always include a preservative booster. These ingredients help the preservative to penetrate the microbes cell walls. Some of the most common preservative boosters are: glycerin, ethylhexylglycerin, butylene glycol, and pentylene glycol. If you're looking for a natural booster, I suggest Propanediol (trade name Zemea).
  • check
    Rule #3: don't forget to add a chelator to the formula. Chelator agents such as EDTA are usually added at 0.05%. Nevertheless, they play an important role in the formulation. An amazing natural alternative is Sodium Phytate (highly water soluble as EDTA).
  • check
    Rule #4: check your pH. Some preservatives only work within a specific pH range, so you want to make sure your product's pH falls inside the range. This information should be provided when you purchase the preservative. Remember to ask if it doesn't happen. When you have to calculate small pH intervals, strips are not the best choice. Invest some money into a pH meter. Usually if they're cheap, they're not very accurate...If you don't know what to buy, below you can see two valid options (the second one is perfect for semi-solids such as creams). Remember to calibrate the instrument before each  use, or the measure won't be accurate. For other tools to build your cosmetics lab, check this post
  • check
    Rule #5: work following the GMPs (Good Manufacturing Practices). In the pharmaceutical world, it's common to say that "the quality of a product doesn't need to be checked, it needs to be built". Don't waste time by creating a product and checking if it's good enough afterwords (=passes stability tests). Instead, use a set of fixed principles that allow you to create a product you already know will pass stability tests. In the specific case of preservatives, do not add a lot of them to compensate for a poor lab manufacturing hygiene. Make sure you follow the GMPs and periodically check and sanitize working areas and instruments. To sanitize use alcohol or bleach. Avoid tap water and make sure your raw materials are not contaminated/expired.
  • check
    Rule #6: always combine two or more preservatives, a.k.a use a "preservative system" to obtain a broad-spectrum protection. Remember to add an anti-fungal compound as well (for example, sorbic acid).
  • check
    Rule #7: Perform microbiological tests! Send 2 oz of the product to a qualified lab for PET test ( Preservative Efficacy Test). During PET test the product is intentionally inoculated with bacteria to see if the preservative can withstand them.  Lastly, perform one test to make sure your product contain a limited number of bacteria AND NO pathogens (not all bacteria are pathogen). Positivity if the PET test means you need to change the preservative system. Positivity in the 2nd test means the product was already contaminated so make sure you review the production procedure and follow the GMPs. Want to perform a quick, inexpensive, DIY test? Then you might want to check this link out.
  • check
    Rule #8 (lotions only). Add a preservative in the water phase and the other one once the emulsion has been formed (cooling down phase). Do not add the preservative when the lotion is still hot. As said before, make sure the pH of the water phase is acid (you can use citric acid to lower the pH ).

Natural preservatives for cosmetics: conclusions.

In this post we have learned that water based cosmetics (for example hair products, face masks, lotions, makeup etc) do need a preservative to perform the way they're supposed to and to be safe.

We have also learned what are the most popular natural preservatives for cosmetics and how to formulate using them; my final recommendation is to try those that are aligned with your or brand's values and see which one gives you the longest shelf-life. 

Finally, to test shelf life and efficacy, you'll need to perform PET test (Preservative Efficacy Test). Since this kind of test can be quite expensive, I would recommend to try using a microbial Test kit before. It consists of a plastic slide coated on one side with terrain for bacterial growth and on the other side with Agar for yeast and mold growth.  

Now I want to hear from you! What is your  natural preservative of choice when making skincare?

    A great reference for people who want to explore diy cosmetic in a safe way, thank you! The amount of preservatives can be a little overwhelming at first. Do you have a recommendation for a preservative to use with bentonite clay? I’m looking into using it in a (anhydrous) deodorant.

  2. Seratopical says:

    Great article and right to the point. I am not sure if this is really the best place to ask but do you people
    have any thoughts on where to hire some professional writers?
    Thx 🙂

  3. Marcus says:

    Great article and thanks.

    My info may be too vague, but for something like making a flaxseed gel, would I add my preservative (or ph adjuster, like Citric Acid) after it’s cooled down or during the heating phase, since this particular product has to be boiled?

  4. Jennifer Joseph says:

    I can’t tell you how helpful this section has been. It’s given me a lot to think about and a lot to do (which I am happy to). I am starting out making lotions, creams, soaps and too many video’s do not provide essential information or decent explanations when they attempt to explain.
    Thanks again

  5. Andrea says:

    Brilliantly Said, I put a oil based preservative in my lip balms especially my soft lip balms in a jar. Dirty fingers dip, spread on lips and most people then dip again and spread. ?

  6. Anelia says:

    Hello, thank you you for your article. It is very helpful! What would you suggest for me to use in my facial moisturizing mask. It a few hurbs tea, milk and essential oils.Thank you again!

  7. Lana says:

    Thankyou for the extensive write up! I am making eyeshadow with a drop of natural food coloring (color from fruits/veggies) and shae butter. What preservative would you recommend? I believe there is a potential hazard mixing certain preservatives with vitamin c? Thankyou!

  8. Palomino says:

    Hello. Thank you so much for this article, it is of great of great help and very informative. However I have a question. I want to make body butter, it doesn’t contain any water but I wish to include a preservative anyway (they’ll be in jars). Would the potassium sorbate be a good choice in your opinion? And most importantly, how would I incorporate it as the dosage is a teaspoon in 5 gallons of water. Your help is greatly appreciated. Thank you Luisa.

  9. Esma says:

    Hi there
    Thank you for all the info.
    Which preservative would you recommend in a magnesium spray? Literally purified water and magnesium salts?

    I tried one but it appears it’s not dissolving in the water.

  10. caroline guitton says:

    Hello!! Thank you for the great post . I am formulating a product, no water but lots of plant powders and 50% clay and then some oils. the clay is absorbant and could absord humidity over time, even if it is in a sealed package and the mask is a one time use. Would you think adding a preservative would help keep it microbe free in case of water absorbtion ? of course there are anti oxidants in the product but I am debating on adding a preservative as well. any ideas on this?? Many thanks, Caroline

    • Luisa says:

      Hi Caroline, before you decide whether to add something , I would perform a quick microbiological test on the product to see what it’s going on. You can ship a sample of the product to a lab for this kind on analysis. Feel free to send me a message if you need more details.

    • Siti says:

      Wow. The case is exactly the same with I’m facing now. My product is teeth powder which contains charcoal, powdered spices and herbs. They are indeed dry, but I am aware that they are having moisture content about 10-15%. I’m still wondering if I should add preservatives or no

  11. Maya says:

    Dear Luisa, thank you so much for the informative article! couldn’t be more grateful:)
    Quick Question: you mention to always combine two or more preservatives. I am a bit confused here. For example, I wanna use Liquid Germall Plus (which I read is a great broad-spectrum preservative yet a synthetic one), then should I combine it with the natural preservatives such as benzyl alcohol and etc as you mention above, or with Leucidal SF Complete(which I also read it can be a natural alternative than the synthetic one). If I can do both, how to calculate the preservatives needed then? Liquid Germall Plus has a suggested usage rate at 0.1-0.5% and Leucidal SF Complete is at 2%-4%. Can I use both in one recipe at 0.5% and 4%? Thanks so much and have a nice day Luisa! 🙂

  12. Leticia says:

    Thank you for a very good information on preservatives. Though I am wondering if a body scrub that contains powder milk and salt needs preservative to add more shelf life?

  13. ons says:

    hey Luisa dear you rock !!! i just started researches on how to create my own body scrubs brand derivative of bio natural ingredients and you helped alot so basically i need to put preservatives though the products is not water base because it will be in contact with water eventually …
    hmm wow amazing thanks alot

  14. Phil says:

    This article offered some excellent directions but think author should have defined “natural” and “preservative.”
    For the former, chemicals such as organic acids and some alcohols may exist in nature but commercial sources are typically synthetic. Other chemicals cited as “natural” are clearly synthetic (e.g. Ethyl Lauroyl Arginate, Caprylyl glycol), and even the “vegetable glycerine” is a product of saponification from oils. Perhaps “naturally compliant” to industry standards such as Ecocert might be appropriate for many of those listed.
    For the latter, think author used Cosmetic Directive listing as defining preservatives – for claim “preservative free.” without clarification, this justifies misleading labeling – arguably to functionality in the EU and more so in US where preservative are not listed as such.

    Folks should note changes to Annex III in Directive limiting such free from claims.

  15. Alpha says:

    Hi, Which preservative would you suggest for an herbal tea rinse with just natural herbs and maybe 1,3propanediol added I am currently thinking about optiphen plus but want to be sure and also is there a more natural one you may suggest?

  16. Colleen says:

    I make body butter with Shea & Kokum butter , aloe Vera , sweet almond oil a very small amount of distilled water , ess oils and eco preservative ..
    What would shelf life be please ?

  17. christie says:

    Hi! Thanks for all your wonderful knowledge! Quick Question, where could we go to get our final products checked for Stability? Are we able to use PH Strips to check PH balance?


  18. Princess says:


    I really enjoyed this article, thank you!
    I’m creating a foaming sugar scrub and a salt soak, both with essential oils. What natural preservative(s) work well in these two type of formulas? And is it ok to package it in clear glass/plastic containers instead of amber?

    I also purchased your ebook, but I don’t know where to go to download it.

    • Luisa says:

      I should see the formula to tell you what preservative to use. As far as the ebook, check your email…I just sent it since you were not able to download it from the website.

  19. Manisha says:

    I really felt this Article was so Right for someone like me who wants All Natural Non Toxic n is overwhelmed by Preservatives ?Thank you for sharing and I have been making my own Face n Body Mists with Hydrosols EO n Carrier Oils n keeping in Fridge without preservatives so I guess I should start adding Preservatives to them now…

  20. Tal B says:

    Thanks so much for this wonderful article!

    What a very confusing place the internet is when it comes to trying to find accurate information regarding which preservatives are best. I ended up purchasing Plantaserve E (phenoxyethanol and ethylhexylglycerin) and potassium sorbate, but, of course, now I have discovered sites that say that this is not a safe choice. After reading this article, I felt like you’d be the best person to consult regarding its safety. I’m simply trying to make skin and hair care for my own use, but still want to make sure it’s safe.


    • Luisa says:

      Thank you for the trust. It’s a good preservative blend, it should be enough, but it really depends on the formula so I can’t tell. Use it at 0.8%. You can send a sample of the product to a lab for microbiological testing when you decide to sell your products (if ever). If you don’t perform the test, being for personal use only, use the product quickly . don’t leave it in the shower for months.

      • Trisha Beckmann says:

        Thank you so much for the information! So very helpful! I would not have thought about what happens if it sits around for a long time, so I appreciate that as well. You have made the daunting task of making homemade body and hair products less terrifying!

        All the best!

    • Luisa says:

      Plantaserve E is a good preservative system, but it’s not natural. I can’t say whether it’s a safe choice without knowing the formula. You can always send a sample to a lab for a quick microbiological test ($35).

  21. Margaret says:

    Hi, I am making liquid African Black Soap. What preservatives will you recommend? The soap will consist of raw honey, castor oil, olive oil, aloe vera oil, and essential oils.

  22. Roxanne says:

    Minasolve Green B appears to no longer be available. Would Biosecur be your current top choice for a certified organic option? Are there any newer products you could suggest since writing the initial article? Thanks!!!!

  23. Mjf says:

    Hello Dear,
    Your article is great ??. Very informative.
    I am formulating an organic face mask at home. I would like to know which natural preservative can be used to extend its shelf life without adding label of added preservatives. It’s water based using rice.
    Another is flaxseeds Gel, for which I need your advice for natural preservatives.
    Kindly also share the maximum shelf life upon adding preservatives,
    Can you please help me out.

    Thank you

    • Luisa says:

      It’s almost impossible for me (and it wouldn’t be professional) to tell you what preservative to use not knowing the formula. With that being said, the preservative Lexgard natural is one of those of “preservative – free” claims, yet it’s an effective one.

  24. Anna says:

    Hi there!

    Thank you for the information. For making a toner – base is hibiscus, with olive leaf extract – what preservative would you recommend?

    Do most essential oil serums also need a preservative? Is there a straight forward guide how to figure out how much to add? I’m very new at this – so thank you for the advice!

    • Luisa says:

      I can’t recommend what preservative to use without knowing the formula. Essential oils serum do require a preservative if they contain water or water derived elements.

  25. Johanna Green says:

    Great article! I’m on 3 pages of notes lol! (Yes people still use pen and paper!) lol anyway… I noticed up above a girl asked about what preservatives would be best used in a flaxseed gel as well. That’s what has brought me here and honestly i have more questions now than ever lol!

    The formula i use is a quarter cup of flax seeds cooked with 2 cups of water. That creates the gel… I strain and then add some glycerin tea tree rosemary vitamin e and a little help oil. I keep it in the fridge but Im wanting to add a preservative as well but here’s where the confusion comes in. The geogard ect seems like a great one but i have no idea at what point in the process to add it lol. I looked into liquid germall plus but saw that is has formaldehyde releasers which threw me off. I feel great that I’m finally asking questions about science… But have no one to talk to that actually understands! Lol

    One more thing! Is sorbic acid… The same thing as calcium ascorbate? I bought powder vitamin c to add into face masks etc. Just curious if it can be added that way in hair products as well! Hopefully i didn’t ask too much of you! Can’t wait to check my email. You’re so smart!

    • Luisa says:

      Hi Johanna, I can’t recommend a preservative specific for your product which I don’t know. I suggest you try different ones to see the differences. Sorbic acid is basically potassium sorbate.

  26. Abby says:

    Hi Luisa!

    Thanks so much for the very informative article! I am doing my research to figure out which preservatives will meet my requirements, but I am feeling unsure how to figure out which ones will blend well for a preservative “system”. Right now, Geogard Ultra seems to work best with my needs, but I’m not sure how to tell which other preservative would work well with it or not?
    On a seperate, I am making paint and pigment particles are unavoidable. How would you suggest I avoid the affects of the particles absorbing the preservative?
    Or are there specific preservatives that work better in that situation?

    Thank you so much,

  27. Walter O. Bliss says:

    Well said here. Keep teaching people. The massive amount of misinformation out there has become an aggravation to me. Clients wanting the impossible is a problem. The cost of the preservative is a serious concern as well. I think people don’t stop to consider there are also economics involved.

  28. Jessica Hall says:

    Hi Luisa, I have been trying to research the use of Glycerin in an otherwise completely anhydrous face/body cream, as I’d like to make my own. Tried a body butter type formula with just oils and butters but would like to explore something I can use on the face and sinks in well. I came across a product that uses oils and butters and then Lecithin and Glycerine are in the formula. I know the specific functions of Lecithin and glycerine in products but I can’t work out for the life of me why they are in this product in this way. Could you lend a hand? If I use Vegetable Glycerine, I don’t want to get it wrong. P.S. there is no preservative in the product I’m referring to; it’s just butters, oils, Lecithin, Glycerine and some essential oils. Please help 🙂

    • Luisa says:

      Hi Jessica, lecithin is a water in oil emulsfier and this is why it allows glycerin to be inserted in an anhydrous product. You can’t have glycerin mixed together with oils and buttes unless you use one.

  29. Farida says:

    Hello just came across your page. Very informative. Thank you
    One question. I have 3 glycerine extracts with licorice, mulberry and papaya. Can I mix with an oil serum? Also would like to add septic white and b3. Help please and preservative. For myself

  30. Elizabeth says:

    Hi, thank you so much for sharing this information. I’ve been learning about making butters and hair creams at home. I want to create products to use within my family. Is there any preservative that I can use in all products I make. Some are with a flaxseed gel. And others are not, rather I’m using butters such as mango, kokum and oils like jojoba, vitamin e, neem, and other oils.

    • Luisa says:

      Hi Elizabeth, you don’t need a preservative if there’s no water in the product. As far as the flaxseed gel, it might already contain a preservative. Check on the ingredients list. The kind and amount of preservative depends on the formula. It’s impossible for me to tell you what to use with confidence.
