making your own cosmeticsWhen I first started making cosmetic products, i.e. lotions, lip balms, sprays, scrubs, etc., I was very hesitant , in the beginning, on which ingredients to use that were all natural and yet effective for preserving all my hard work from going rancid.
After years of working with many types and lots of research, here is a list of helpful and useful natural ingredients that are safe to use for preserving your cosmetic recipes:

I think your blog is fantastic. I’m starting a natural skincare company and am using mostly butter and creams (no water or milk). I understand that I don’t need to put preservatives in these formulations. However, I would like to add something that inhibits bacterial as least a little. I am thinking of standardly adding vitamin E to all the butters and creams. Later on we will get into some formulations that use distilled water.Can you give me a little more information on the following? A friend sent them to me after attending one of her work workshops on lotion making: Dermofeel 688 INCI: p-Anisic Acid and Glyceryl Caprylate (and) Glyceryl Undecylenate. Also, the natural preservative mixtures that you mentioned, can I get them already mixed? If I can get them already mixed, what percentage should they be of my formulation?

I found this mixture of ingredients here; http://www.kinetiktech.com/materials/index.php. and here’s a link to a great .pdf about making your own natural “green” formulations; http://www.kinetiktech.com/docs/GreenGuide-latest.pdf . hope that helps :)

“To avoid parabens, Jason Natural Cosmetics has switched from methylparaben to a natural preservative that has the same shelf life–2-3 years–as the paraben-based preservative. In January 2003, for its Shaman Earthly Organics line, Jason debuted a preservative that consists of sodium benzoate (salt crystals), potassium sorbate (powder from mountain ash trees combined with potassium salt) and grapefruit-seed extract. “Now our preservative systems are food grade, which adds to the purity level of our products,” Light says.

Aubrey Organics solved the preservative puzzle with a mixture of grapefruit-seed extract and vitamins A, C and E, which inhibits micro-bacterial growth and helps retard the ingredients’ decay. All of the company’s 250 personal care products are made with this natural preservative, says Aubrey representative Sandie Coretti, and have shelf lives of 18 months to 3 years–considerably shorter than products made with synthetic preservatives, which can last 5-8 years, Coretti says.

The Obsessively Organic line by Kiss My Face uses a blend of all-natural preservatives, Byckiewicz says. This blend assures the products have a shelf life of up to 2 years.

As companies seek alternatives to synthetic preservatives, the industry as a whole is moving forward on issues that are just as challenging. What OCA. OTA and virtually everybody else in the industry agrees on is that the higher the level of organic ingredients in a personal care product, the safer it is for the consumer. How quickly they can agree on standards that they can support is another matter. Until then, consumers will have to educate themselves about label claims–and rely on their scruples…..

thanks so much to  http://eroscent.com/blog/resources-and-guides/natural-preservatives-for-your-cosmetic-recipes/ for the useful tips! They match my own findings!

Making your own natural cosmetics allows you to control the ingredients and produce recipes created specifically for you. The downside to this is that natural ingredients tend to have a limited shelf life. Learning what ingredients are natural preservatives, and how to use them, will prevent rancidity and anti-oxidation in your homemade cosmetics.

Here’s a list:

Benzoin Resin (also called Styrax) is a less well known preservative and fixative. For centuries, it has been an important ingredient in the making of incense due to its fixative qualities. Benzoin has a rich sweet scent that is quite distinctive. Because it is easily absorbed through the skin, it should be diluted in alcohol before use in cosmetic recipes. Benzoin resin is often found in facial toning and facial oil recipes to improve their shelf life.

Borax is a common ingredient that used to be found on the laundry shelf of most grocery stores. It is a natural cleaner and preservative, and it often found in lotion, cream, bath salt and bath scrub recipes.

Honey is a marvelous natural preservative. One teaspoon to one tablespoon of honey can be added to most any natural cosmetic recipe to improve its shelf life. My personal facial elixir has honey as an essential component, but I also add it to salts, scrubs, facials, creams and lotions.

Jojoba is one of my favorite natural preservatives because, like honey, it is just so very versatile. Jojoba is often combined with those oils that are known for having a limited shelf life, such as almond oil, apricot kernel oil, and rosehip seed oil. Get in the habit of substituting a tablespoon of jojoba oil for the more fragile carrier oils to improve the shelf life of your home made creations.

Vitamin E Oil is another natural preservative that I use quite often. If you are making a preparation for the skin, add a teaspoon of vitamin E oil to prevent rancidity and as an anti-oxidant. Vitamin E oil has the additional benefit of being safe to use for recipes for babies and small children.

When creating my own cosmetic recipes, I tend to use a two-pronged approach. Benzoin and vitamin E in a facial oil, for instance, or jojoba and borax in a lotion. Incorporating these natural preservatives in your own creations will enhance your cosmetics making repertoire considerably.

Preservative-Free Formulations

It’s important to remember that your preservative-free, natural products will not stay fresh for as long as commercial products do. By making your products in small batches that you use up within a short period of time, your products will stay fresh and you eliminate the need to preserve your products with harsh chemical preservatives. Formulating anhydrous products is another way to eliminate the need for chemical antimicrobial preservatives. Bar soaps typically do not require an antimicrobial but stay fresher when an antioxidant is used. You do have natural antioxidants available to you for this purpose. Switch to the use of natural balms made of oil and butter instead of creams and lotions which require an antimicrobial preservative. Create dry bath products such as bath salts, milk baths, bath bombs, bath teas etc. to eliminate the need for antimicrobial preservatives. Salt scrubs, bath oils, bath melts and other oil based products can stay fresh as long as water is not introduced to the container during use. Again, you may wish to use a natural antioxidant to keep the oils fresh. Minimize contamination potential by choosing your packaging carefully. Dispensing bottles are better than open mouth jars.

Direct sunlight and UV rays, oxygen, heat, moisture and bacteria from your fingers can all be detrimental to your products. Below are several tips for protecting and preserving your preservative free formulations:

  • Be sure your hands, work surface, and utensils are clean/sterile when preparing your products. This will help ensure that you do not introduce bacteria or contaminate your batch. Commercial skin care production is undertaken in extremely clean and sterile environments for this same reason.
  • Store your products in dark containers or opaque packaging to keep them away from the harmful effects of sunlight.
  • Ensure that your packaging is airtight. Natural products can oxidize and go rancid when exposed to air.
  • Heat can also be damaging to natural products. Store products in a cupboard or other cool place.
  • Because our fingers can be a host to bacteria, try to avoid dipping your fingers into your jars and bottles. Instead, use a clean spoon, toothpick, popsicle stick or other appropriate utensil to obtain the amount that you wish to use. Lotion pumps and PET bottles with turret or disc tops are wonderful for dispensing more fluid ingredients such as lotions and gels.

If you are formulating something that contains water, milk, hydrosols or other aqueous liquids, you will have to preserve the product or use it within 3-4 days refrigerated. It simply is not optional. Water provides a medium for harmful bacteria, mold, yeast and fungi to grow over time. If used, a contaminated product could cause severe health problems, blindness and even death. Your product must be adequately preserved to prevent contamination and microbial growth.

So what are your options and how will your product differ from those found on store shelves?

  1. First, even with a preservative, your product is still a healthier alternative to commercial products because the remaining ingredients within your product are natural or gentle.
  2. Second, you won’t use unnecessarily high levels of preservatives like most commercial manufacturers use.

Your options will be based on your formulation and what it contains.

Essential oils are the most natural antimicrobials you will find.

Some natural product manufacturers have successfully used oils such as tea tree or combinations of various essential oils to maintain product integrity.

According to Preservatives for Cosmetics by David C. Steinberg, essential oils that have demonstrated antimicrobial activity include;

caraway,

cinnamon,

clove,

cumin,

eucalyptus,

lavender,

lemon,

oregano,

rose,

rosemary,

sage,

sandalwood

thyme

and actually many others as well that are not mentioned here…

Unfortunately, the percentage required to adequately protect a product from microbial growth generally exceeds the recommendations for safe amounts of essential oils to use in skin care products.

Grapefruit seed extract or citricidals are another class of antimicrobials that are considered by some to be more natural than the parabens.

Choose your citricidal preservative carefully as some of them have questionable ingredients. A good quality citrus seed extract should not contain additional preservatives.

Parabens are preservatives that are available in small quantities for crafters and small businesses. Paraben based preservatives include Germaben, Germaben II, Phenonip, Methyparaben and other types such as Germall and LiquaPar Oil.

Antioxidants

An anti-oxidant is a preservative that reduces the rate of oxidation in oils that oxidize quickly. Oxidation is a chemical process that occurs when oils or other natural ingredients are exposed to oxygen. Anti-oxidants extend the shelf life of your products by reducing the rate of oxidation of your oils. Use an antioxidant in any formulation which contains fragile oils such as sweet almond, hemp, avocado, flax or evening primrose. You can add antioxidants directly to your oils to help keep them fresh, or you can add the antioxidant to the oil phase of your recipe. Lip balms, lotion bars, creams, lotions, scrubs and any other product containing oils can benefit from the addition of an antioxidant.

T-50 Vitamin E Oil

Vitamin E contains natural antioxidants which extend the life of your products. Gamma tocopherol, a component of Vitamin E, is a great antioxidant for protecting cosmetic formulations. T-50 has a larger amount of gamma tocopherols than other forms of Vitamin E oil.

While the alpha tocopherol in the 250, 1000, and 1400IU/g oils is wonderful as an in vitro antioxidant, studies show that the gamma tocopherol in the Vitamin E T-50 oil is a better antioxidant for oils/lipids in cosmetic formulations. T-50 has a higher content of gamma tocopherols and can be used at a rate of .04% or 400ppm to adequately protect your oils.INCI Nomenclature: Tocopherols

Rosemary Oil Extract

Rosemary oil extract (ROE) also acts as a natural antioxidant. ROE can impart its own aroma into your products, so keep that in mind when using it. As a preservative, add .15 to .5 % of our undiluted Rosemary oil extract to your products.

Our Rosemary oil extract is a 100% pure extract. It has not been diluted in a vegetable oil.

INCI Nomenclature: Rosmarinus Officinalis (Rosemary) Leaf Extract

Anti-Microbials

An anti-microbial is an ingredient or substance that helps to destroy unwanted micro-organisms such as bacteria. In the context of handmade skin care products, an anti-microbial helps preserve a product by keeping the product free of these unwanted micro-organisms.

Grapefruit Seed Extract

Grapefruit Seed Extract (GSE) is a citrus seed based anti-microbial used as a preservative in skin care products. GSE is made with the extracts of citrus seeds and pulp. It is blended with vegetable glycerin to make it non-irritating to the skin and mucous membranes when used in formulations. GSE is even safe enough to use as a disinfectant for drinking water when necessary.

Our Grapefruit Seed Extract is professional strength. It is 60% GSE in 40% vegetable glycerin. It is not the usual 33% found elsewhere. Please be sure to take that into consideration when using a recipe that simply calls for “GSE”. GSE has a shelf life of 7-9 years. It is said to be anti-microbial, anti-septic, anti-bacterial, astringent and does also have some antioxidant activity.

Use GSE at .5 to 1% to preserve most formulations, or use at 2% to create anti-bacterial creams, salves, rinses and soaps. Please note that adding 2% GSE to your products does not mean that you can market or label the product as an “anti-bacterial” product.

Wear gloves while handling Grapefruit Seed Extract. GSE can be irritating to the skin in its undiluted form.

INCI Nomenclature: Grapefruit (Citrus Grandis) Extract (and) Glycerin

Germaben II

Germaben II is a convenient, ready-to-use broad spectrum anti-microbial preservative for personal care products such as shampoos, conditioners, lotions, creams, body sprays and other formulations. It is highly effective against gram positive and gram negative bacteria, yeasts and molds and does not need any additional preservatives. It is a clear, viscous liquid with mild odor. It is soluble in both oil/water emulsions and aqueous formulations up to a level of 1.0%. At 1%,

Germaben II provides 0.30% Germall II, 0.11% methylparaben, 0.03% propylparaben, and 0.56% propylene glycol. Germaben II should be added slowly to your product under gentle agitation before the addition of fragrance oil.

Recommended usage rates are provided only as guidelines for proper preservation. All new formulations should be challenge tested to ensure preservative efficacy.

INCI Nomenclature: Propylene Glycol (and) Diazolidinyl Urea (and) Methylparaben (and) Propylparaben

Germaben II-E

Germaben II-E was developed to protect formulations that contain ingredients that inactivate parabens. It is a liquid preservative system that contains 20% Germall II, 10% methylparaben, 10% propylparaben, and 60% propylene glycol. It is used to preserve water-in-oil and oil-in-water emulsions but should not be used in aqueous formulations. It is readily soluble at 1.0% and should be added to the emulsified product under gentle agitation before the addition of fragrance. Germaben II-E is a complete preservative effective against gram positive and gram negative bacteria, yeasts and molds. It is compatible with almost all cosmetic ingredients including surfactants and proteins.Recommended usage rates are provided only as a guideline for proper preservation. All new formulations should be challenge tested to ensure preservative efficacy.

INCI Nomenclature: Propylene Glycol (and) Diazolidinyl Urea (and) Methylparaben (and) Propylparaben

Liquid Germall Plus

Liquid Germall Plus is a broad spectrum, water soluble preservative for oil-in-water and water-in-oil emulsions and water soluble formulations. It is highly effective against gram positive and gram negative bacteria, yeasts, molds and commonly found organisms. It is compatible with most cosmetic ingredients and has no known inactivators. Liquid Germall Plus is effective at low concentrations of 0.1 – 0.5% (the higher % should be used in conjunction with high protein and complex formulations). It remains active through a pH range of 3-8. It should be added during the water phase or to the emulsified portion of the formulation at a temperpature of 120F or less. Liquid Germall Plus has a safe toxicology profile and has been evaluated as safe for both rinse-off and leave-on formulations. It is a good choice preservative for shampoos, conditioners, lotions, creams, body washes, body sprays and other such formulas.

Recommended usage levels are meant only as a guide for proper preservation of your product. All new formulations should be challenge tested to ensure that your preservative is working properly.

INCI Nomenclature: Propylene Glycol (and) Diazolidinyl Urea (and) Iodopropynyl Butylcarbamate

LiquaPar Oil

LiquaPar Oil is a clear, liquid blend of isopropyl, isobutyl and n-butyl esters of para hydroxybenzoic acid. It is a very stable and effective preservative against gram positive and gram negative bacteria, yeast and mold. LiquaPar Oil is readily incorporated into various types of formulations, including anhydrous products, without heating. It is a good choice for salt scrubs and bath oils where no water is present but may be inadvertently introduced to the container during regular use. The recommended usage rate is 0.3 – 0.6% however, in complex formulations, 0.1% Germall II may be required for adequate preservation.

Recommended usage rates are meant as guidelines only. All new formulations should be challenge tested to ensure proper preservation.

INCI Nomenclature: Isopropylparaben (and) Isobutylparaben (and) Butylparaben

  1. ouch, i wish i could use germawhat :D i don’t know where i can purchase it. I’m such a skincare maniac :D

  2. What about Aloe Vera as a lotion base? I know there are certain aspects of Aloe that allow for “preservation,” but will using it as a base combined with natural oils allow for a suitable shelf life?

    • Not really, unless you are only using it for yourself. Aloe is great, and a fabulous addition to any lotion base, but doesn’t really constitute a preservative, but if you are just using it for yourself, friends or family, and it’s used up within a month, it won’t really matter. Only if you plan on actually putting it on a shelf somewhere, then I would use additional natural preservatives as mentioned above to be safe. Hope that helps :) Thanks for the comment!

    • depends which oils you are using with it, and how long of a shelf life you are talking about

  3. article is very informative. However where do you go to find the suggested preservatives in large amounts for example the benzoin.

  4. What is the actual shelf life for products with natural preservatives?

    3 months?

    If I wanted to create a product with a shelf life of 6-8 months, will have to resort to harmless synthetic preservatives?

    • “To avoid parabens, Jason Natural Cosmetics has switched from methylparaben to a natural preservative that has the same shelf life–2-3 years–as the paraben-based preservative.

  7. Thank you for the wonderful information! I own a small Sustainable Home service company that is expanding to provide natural products and we are struggling with the same issue with finding the right preservatives. Because we are new to this arena we aren’t sure how to estimate the shelf life of our diaper spray formulation (largely hydrosols, aloe and Castile soap). Aside from obtaining estimated shelf life of ingredients from our suppliers, how might we determine the shelf life of our products?

    Thank you so much!

  8. I’m getting into making natural products to sell. Since I’m only one person, I won’t be mass-producing products that will sit on store shelves. What’s the best type of preservative for me to use, in these early days? So far, I’m only making lip balm, and I know from personal experience that honey is the perfect preservative; I’m still using the balm I made a year ago. What’s the ratio of GSE and Vitamins A, C, and E used by Aubrey Organics?

  9. Hallo.Am well pleased with your very informative column,keep up.Am very much interested with your knowledge and how easily can i get to talk to you since i have very many questions

  10. I have a question please, if I’m using a homemade shampoo made of castile soap and coconut milk (which is aqueous of course), can I extend its life by using one of the mentioned preservatives? or do I still have to use it within 3-4 days refrigerated??!! I really need to know that please..

  11. I like the valuable info you provide for your articles. I will bookmark your blog and test again here frequently. I am slightly certain I’ll be informed a lot of new stuff right right here! Best of luck for the next!

  12. This is the most informative blog I’ve come across, thank you for sharing this very imformative information & your knowledge! :)

  13. Hi, I made ny first hyaluronic acid serum for face and body. I used the pill instead of pure just to start until my pure powder comes jn. The pills have hyaluronic acid in them. I used an aloe vera base that was preserved with sodium benzoate (less than 2% it states). I placed this mixture in a clean bittke and its been in my fridge for about a month. I also added to a coq10 mix with pure jojoba, Emu oil, dmae powder, and vitamin a. I also have a serum that used a aloe vera base I purchased from the store that has parabens already in it, but added dmae powder, hyaluronic acid, witch hazel, many like including my mix of coq10, jojoba, cocoa, shea, Emu, coconut, rosehip, borage, evening primrose, flaxseed, squalane, retinoyl palmitate (vit. A pills), grapeseed, been, palm kernel oils, with alpha lipoic acid, MSM, collagen, and extract of frankincense (extracted in raw shea butter), lime, lemon, Orange, tea tree, and almond (organic store sub alcohol). I ended it with by adding finely ground pure cinnamon bark to it, let it extract for a week in the fridge (shaking often), and then strained it in a sterile environment. I made this to use for myself but also my family. The aloe vera gel for the last one also had xanthan gum and polysorbate 20&80 in it. It’s been in my fridge for about two months, and smells of cinnamon. It doesn’t smell, I just want to be sure its still ok to use. it feels divine! What do you chunk of these three sediment I’ve made so far??? How ling can they last or should I chuck them and start over using more essential like and possibly a nearly natural preservative for shipping to my family? Thanks so much for the advice.

    • wow! this sounds divine! And since you’re not putting it on store shelves and just for family it should last at least 6 months, or more since it does have other preservatives in it.

  14. I just want to know is it possible to preserve coconut milk for few months

  15. Thanks for sharing your recipes! Very informative article

    Hello, your article is fantastic, I want to start making my own perfumes with essential oil and jojoba oils, everyone keeps saying to put 100 vodka in the mix – can I just use the oils or should I add vodka, benzoin or glycerin? Thanks Raea

    • thanks for your comment Raea! you can use anything you want for a perfume, depending on how you want the final product to turn out; if you like a strong roll-on type you can just use the jojoba, or if you want a typical eau de toilette or cologne- using vodka or perfumer’s alcohol would be great. Benzoin is more of a fixative for your scents, and I don’t use glycerin in any of my perfumes, sometimes in other products but not in perfumes. hope that helps :)

    • there are tons of natural preservatives you can use, but none are needed if you’re just using it on yourself. for instance; a mixture of grapefruit-seed extract and vitamins A, C and E, which inhibit micro-bacterial growth and help retard the ingredients’ decay are a great preservative mix.

    Hello, I’m starting my own gift basket company where I will be making natural body scrubs/butters for one of my baskets (Spa Basket) however I want to know what natural preservative could I use that will make it last at least 6 months? Per your research, the T-50 Vitamin E Oil has a 2 year shelf life and Grapefruit Seed Extract has a 7-9 year shelf life. Is the shelf life the same once combined with all the other natural ingredients, or is it reduced due to the oxidation/rancidity rate of the other ingredients? Can I use GSE/vit A,C,E in a body scrub/butter? Also, what’s good to use with jojoba oil?

    • thanks so much for your comment! Using a mixture of grapefruit-seed extract and vitamins A, C and E, which inhibit micro-bacterial growth and help retard the ingredients’ decay are a great preservative mix, and should be perfect for what you need. Not sure what you mean about what’s good to use w/ jojoba oil…it goes great w/ everything! Best of luck to you in your business venture and Happy Holidays~! :)

  20. What can I mix with coconut oil so that it has a long-shell life and treats acne better?

    Sometimes referred to as GSE, the Grapefruit Seed Extract, is a highly concentrated blend of the pink pulp, orange skin, and seeds of the grapefruit. Already known as a healthy fruit to eat or juice to drink, the extract form is a more efficient way to consume the valuable nutrients the grapefruit has to offer. You’ll notice that the Grapefruit Seed Extract offers an immense variety of benefits for the human body. –

  23. Great post. I used to be checking constantly this weblog and I’m inspired! Very helpful info specifically the closing part :) I care for such information much. I was looking for this particular info for a long time. Thank you and best of luck.

  24. Hi, I do think this is a great web site. I stumbledupon it ;) I will revisit once again since i have saved as a
    favorite it. Money and freedom is the best way to change,
    may you be rich and continue to guide others.

  25. I’ve loaded your site in 4 different web browsers and I must say this website loads a lot quicker then most. Would you mind contacting me the company name of your web hosting company? My personal e-mail is: muhammadhinojosa@gmail.com. I’ll even sign up through your own affiliate link if you would
    like. Cheers

  26. Hi there! I could have sworn I’ve been to this website before but after going through many of the posts I realized it’s new to me.
    Anyhow, I’m certainly delighted I discovered it and I’ll be book-marking it and checking back often!

  27. Greetings from Idaho! I’m bored to death at work so I decided to check out your blog on my iphone during lunch break. I really like the knowledge you provide here and can’t wait to take a look
    when I get home. I’m amazed at how quick your blog loaded on my cell phone .. I’m not even using WIFI, just 3G .
    . Anyways, great blog!

  28. Heya i’m for the primary time here. I came across this board and I in finding It really helpful & it helped me out much. I hope to provide something back and help others like you aided me.

  29. I think your blog is fantastic. I’m starting a natural skincare company and am using mostly butter and creams (no water or milk). I understand that I don’t need to put preservatives in these formulations. However, I would like to add something that inhibits bacterial as least a little. I am thinking of standardly adding vitamin E to all the butters and creams. Later on we will get into some formulations that use distilled water.Can you give me a little more information on the following? A friend sent them to me after attending one of her work workshops on lotion making: Dermofeel 688 INCI: p-Anisic Acid and Glyceryl Caprylate (and) Glyceryl Undecylenate. Also, the natural preservative mixtures that you mentioned, can I get them already mixed? If I can get them already mixed, what percentage should they be of my formulation?

  30. Benzoin Resin (also called Styrax) is a known sensitizer. I am one of those people that itch from benzoin.
    Honey, unless it’s used in it pure state, will grown nasties in any formula made with water. It is not a preservative.
    I don’t see anything in Jojoba that would make it a natural preservative. It is technically a plant wax, so it might be better suited as an anti-oxidant.
    Vitamin E Oil is an anti-oxidant only. It helps extend the shelf life of oil or butters, but it will not preserve.
    If you go to lotioncrafter.com they offer natural alternatives that can be used as preservatives.
