How To Use Potassium Sorbate In Cosmetics?
In order to use potassium sorbate you need to formulate a solution by mixing it with water typically a 25% solution. I would like to add 0.1% to 0.2% of potassium sorbate to a liter of lotion that’s already preserved with phenoxyethenol for added protection against yeast and mold.
How much potassium sorbate should I use in cosmetics?
It is almost always used in conjunction with other preservatives due to its weaker activity. The independent Cosmetic Ingredient Review panel found that potassium sorbate is safe in amounts up to 10%; it is most used in skin care products in amounts of 1% or lower.
How to use potassium sorbate as a preservative in skincare?
How to Use Potassium Sorbate Preservative in Formulations – Potassium Sorbate should be mixed with other preservatives to provide adequate protection from bacteria. It is most effective at a pH of 4.4; formulations including Potassium Sorbate should have their pH lowered to increase efficacy.
Be sure to test your product pH before adding preservatives to ensure that they work most effectively. It is essential to pay attention to recommended usage levels as large amounts of sorbic acid can be irritating to the skin. Sorbic acid is also an unsaturated fatty acid that is subject to oxidation.
This means that it will begin to yellow over time when exposed to light if it is not mixed with an antioxidant agent. You should also add Potassium Sorbate into your formula at a temperature below 60°C (140°F), or it will begin to sublime. If you add it after oil and water have been combined, it is recommended to pre-dissolve it in water to make incorporating it easier.
Is potassium sorbate a good preservative in cosmetics?
What is Potassium Sorbate and what does it do? – is a mild preservative, it has antibacterial and antifungal properties that ensure your skincare and cosmetic products are shelf-stable and remain hygienic for use in your daily routine. It is used much like benzyl alcohol as an alternative preservative to parabens – which have become controversial due to potential health effects.
How do you dissolve potassium sorbate?
Potassium Sorbate Potassium Sorbate 
CAS No.24634-61-5 Potassium sorbate is the inactive salt of sorbic acid. It readily dissolves in water where it converts to sorbic acid, its active form, at a low pH. Sorbic acid is very pH dependent. While it shows some activity up to pH 6 (about 6%), it is most active at pH 4.4 (70%).
- At pH 5.0 it is 37% active.
- As sorbic acid, it is considered to be active against mold, fair against yeast and poor against most bacteria.
- Sorbic acid is an unsaturated fatty acid and as such is subject to oxidation (use of an antioxidant like Mixed Tocopherols T50 is recommended).
- It is also sensitive to UV light and may turn yellow in solution.
Gluconolactone is reported to stabilize potassium sorbate against discoloration and darkening in aqueous solutions and may be useful in stabilizing sorbic acid in the water phase of a product. While sorbic acid is naturally occurring in some fruits (like the berries of the mountain ash), virtually all of the world’s production of sorbic acid, from which potassium sorbate is derived, is manufactured synthetically, and is a nature-identical compound chemically equivalent to the molecule found in nature.
Sorbic acid can cause contact dermatitis at concentrations above or below 0.5%. Studies show that if it is used at a concentration of no more than 0.2% it is unlikely to constitute a safety hazard. Potassium sorbate is not a broad spectrum preservative for cosmetic use and should be combined with other preservatives.
If potassium sorbate is used as a preservative, the pH of the finished product may need to be reduced for potassium sorbate to be effective. This is because potassium sorbate is the inactive salt form of sorbic acid. To be useful, the pH of the formulation must be low enough to release the free acid for useful activity.
| pH | % Active Sorbic Acid |
| 3 | 98 |
| 4 | 85 |
| 5 | 37 |
| 6 | 5.5 |

All cosmetic products should undergo microbial testing to ensure the efficacy of any preservative system. INCI: Potassium Sorbate California Prop 65 Statement: The following statement is made in order to comply with the California Safe Drinking Water and Toxic Enforcement Act of 1986.
- This product is not known to the State of California to cause cancer, birth defects or other reproductive harm.
- At temperatures above 60°C (140°F), potassium sorbate can begin to sublime.
- Add to the water phase of formulations at a temperature below 60°C (140°F).
- If adding it after oil and water phases have been combined, predissolving the required potassium sorbate in a portion of the water phase will make it easier to incorporate into the formed emulsion.
Use in formulations with pH 5 or lower. Recommended Use Levels: 0.1% – 0.5% Appearance: Extruded, Spherical Powder Solubility: Soluble in water up to 58% Try out these formulations using this ingredient: : Potassium Sorbate
Is potassium sorbate good for face skin?
Discussing the safety and efficacy of this natural preservative in skin care and cosmetics – Posted on December 22, 2022 Written by: 100% PURE ® We’re thrilled to see the world of clean beauty grow, and hope that you are, too! When it comes to beauty, more and more products are available every day – giving shoppers more cruelty-free and sustainable options. Despite the growth of this industry, there are a few issues that need some addressing.
- One such issue is unnecessary fear, which sometimes happens when an ingredient is misunderstood.
- One ingredient that comes to mind is potassium sorbate, which is used as a common preservative in makeup and food.
- While the name might not sound as familiar or straightforward as “organic lavender” or “cold-pressed coconut oil,” it’s not as scary as you might think.
Did you know that potassium sorbate actually comes from a tree? That’s just the beginning! Let’s take a closer look at potassium sorbate, how this mild preservative is used, and how safe (or unsafe) it truly is to our health – plus its benefits in skin care and cosmetics. What Is Potassium Sorbate? Potassium sorbate is a preservative found in food, skin care, cosmetics, and personal care products. It is the potassium salt of a naturally occurring compound known as sorbic acid. This ingredient kills microorganisms and prevents the growth of bacteria, fungi, and mold.
Potassium sorbate occurs naturally from the vibrant berries of the rowan tree (Sorbus aucuparia) or mountain-ashes, which are shrubs or trees known for their hardiness in cold weather. In its pure form, potassium sorbate is a white, water-soluble salt that appears as small grains or crystals. While potassium sorbate can be naturally sourced, the most common way of producing potassium sorbate is through synthetic methods; specifically, by neutralizing sorbic acid with hydrogen peroxide.
The result is a compound identical to that found in nature. Benefits and Uses of Potassium Sorbate Potassium sorbate has a wide variety of uses. This mild preservative has been valued for decades for its antimicrobial properties, and is an especially effective food preservative found in dehydrated meats, dairy products, and pastries.
It’s especially common in dried fruit and is also often used to help preserve wine. Potassium sorbate can prevent the growth of fungi, mold, yeast, and other potentially harmful foodborne pathogens. Although this natural preservative isn’t as effective against bacteria, and will need to be complemented with other preservatives, such as rosemary or sodium benzoate.
Potassium sorbate makes an effective preservative in food, but this ingredient’s antimicrobial and antifungal properties are easily transferred to skin care and cosmetic products. Since this preservative is a viable alternative to more harmful parabens, it’s become quite popular in clean skin care and natural makeup,
As a result, potassium sorbate is often used in products at a concentration of up to 1% as a preservative. However, in recent years, the word “preservative” has developed a strange stigma as something that’s dangerous or harmful to our health – but this assumption needs to be talked about to be fully understood.
What Preservatives Do Any product comprised of certain components will naturally degrade over time; this is where preservatives come in. Preservatives help to maintain ingredient stability and ward against bacterial population, keeping it safe to use over time with relatively the same quality and performance – at least, until the product hits its expiration date.
Preservatives are used in skin care products to keep us safe. Specifically, they help prevent the onset of harmful pathogens like mold, bacteria, and fungi. This system is crucial in products that contain water: the key conduit of bacteria, especially when combined with oxygen. The more water it contains, the stronger and more concentrated the preservatives will need to be.
Since our skin has a hard-enough job just keeping us, well, together, it’s all-the-more important to make sure every formula has its own preservative system in place and the products we apply topically are effective at staving off harmful bacteria. The bottom line is preservatives serve an important role, and without these front-line defenders, your beauty products will quickly spoil.
Can potassium sorbate be used alone as a preservative?
What is potassium sorbate? Potassium sorbate is a chemical additive. It’s widely used as a preservative in foods, drinks, and personal care products. It is an odorless and tasteless salt synthetically produced from sorbic acid and potassium hydroxide. Potassium sorbate prolongs the shelf life of foods by stopping the growth of mold, yeast, and fungi.
Which is better sodium benzoate or potassium sorbate?
Considerations for choosing the best preservative combination. Many food manufacturers, optimize the shelf life of their product through the use of preservatives, of which there are very many different types. Clearly, the choice of preservative used is going to have an impact on a facility’s HACCP plan and also on the distribution of the product being manufactured.
This is where a scientific approach to plant contamination really shows its power. Once the contaminant load in a plant has been analyzed, along with contaminants routine testing found in finished product, it becomes possible to scientifically determine (through such testing) the best preservative for that product.
The most common preservative combination seems to be the combination of potassium sorbate and sodium benzoate. This combination, however, may not be the best choice for your product. Potassium sorbate has a reasonable taste and even adds a bit of sweetness.
Sodium benzoate, however, has a thoroughly lousy flavor. Various flavor houses offer special flavorings they claim are able to mask the wretched flavor of sodium benzoate but it seems to be a matter of opinion whether there exists any masking agent for sodium benzoate that actually lives up to its promise.
There is also another, more serious, problem. Sodium benzoate is itself not all that well preserved in all cases. In the presence of vitamin C and heat (as might be found in a pasteurization step of an acid food), sodium benzoate is known to decompose to carbon dioxide and benzene.
- The probable human LD50 of benzene may be as low as 50 mg/kg (50 ppm – oral administration).
- Benzene is therefore quite toxic.
- Benzene is also a confirmed human carcinogen (International Agency for Research on Cancer – IARC – Group 1).
- Even intact sodium benzoate has managed to generate controversy, lately.
For example, there has been a linkage reported between use of this preservative and hyperactivity in young children. Another study has suggested cellular damage to result from this preservative. Perhaps it would be better not to follow the herd in the matter of using sodium benzoate in your product.
- In fact, as these side effects become more widely known, it might even be wise to advertise the absence of sodium benzoate in a product, especially if the absence of sodium benzoate becomes a competitive advantage.
- The best choice of preservative is to find what works against the very microorganisms that are causing a given spoilage problem.
Such information should be part of a HACCP plan anyway. Use of a preservative cocktail that has been demonstrated effective against potential contaminants is the definition of a Critical Control Point (CCP). This science-based approach is one way to knock down two birds (product shelf-life and food safety regulatory affairs) with one stone.
Is potassium sorbate toxic in cosmetics?
More Scientific Information: – Sorbic Acid is a straight-chain monocarboxylic acid also known as 2,4-hexadienoic acid. Potassium Sorbate is the potassium salt of Sorbic Acid. In cosmetics and personal care products, Sorbic Acid and Potassium Sorbate function as preservatives and antimicrobial agents.
What is the safest preservative for cosmetics?
Sodium benzoate : A food and cosmetics preservative that has the Generally Recognized as Safe (GRAS) status given by the FDA Phenoxyethanol: An ether used as a fragrance or preservative that’s considered practically non-toxic when ingested and non-irritating when diluted
What is the most widely used preservatives in cosmetics?
What are parabens, and why are they used in cosmetics? – Parabens are a family of related chemicals that are commonly used as preservatives in cosmetic products. Preservatives may be used in cosmetics to prevent the growth of harmful bacteria and mold, in order to protect both the products and consumers.
How do you calculate how much preservative to use?
How much do I need to use? – Each preservative will have a different recommend usage rate, which you can get from your supplier. I made a handy-dandy preservative calculator that you can use here, Or, for the math: Let’s say your preservative should be used at 1%; if your recipe contains 100g of ingredients, that’s approximately 1g of preservative.
- Figure out how much your recipe weighs. Either add up the weights of all the ingredients or weigh the final product.
- Figure out the recommended usage rate of the specific preservative you are using. Your supplier will provide this. Choose the higher end of the range since we’re not manufacturing in sterile labs.
- Multiply the weight of your product by the usage rate percentage, and divide that number by 100. So, if your concoction weighs 50g and the usage rate is 2.5%, that would be 50 × 2.5 = 125.125 ÷ 100 = 1.25. That means you should add 1.25g preservative to your concoction.

Shelf Life: 12.00 month(s) or longer if stored properly.
Can you mix sodium benzoate and potassium sorbate?
CAS No.: 532-32-1 Sodium Benzoate is the inactive salt of benzoic acid. It is soluble in water where it converts to benzoic acid, its active form, at a low pH. Benzoic acid is very pH dependent. While it shows some activity up to pH 6 (about 1.55%), it is most active at pH 3 (94%).
- As benzoic acid, it is considered to be primarily an anti-fungal, but it shows some activity against bacteria.
- It is poor against pseudomonads.
- Benzoic acid is inactivated by non-ionics and by raising the pH.
- Sodium Benzoate is not a broad spectrum preservative for cosmetic use and should be combined with other preservatives.
If Sodium Benzoate is used as a preservative, the pH of the finished product may need to be lowered enough to release the free acid for useful activity. Sodium Benzoate is often combined with Potassium Sorbate in low pH products to provide a synergistic preservative effect against yeast and mold.
| pH | % Active Benzoic Acid |

There is some concern that Sodium Benzoate in combination with L-Ascorbic Acid in products can form Benzene, a known human carcinogen. The presence of ascorbic acid and benzoates alone does not lead to the formation of benzene. Certain additional conditions are required for trace levels of benzene to form, including heat, ultraviolet light and metallic ions in the mixture.
- Therefore, a product containing ascorbic acid and benzoates will not necessarily contain any detectable levels of benzene.
- The use of EDTA, which chelates metallic ions can therefore be of assistance in the inhibition of benzene formation.
- Citric Acid is not thought to induce significant benzene production in combination with Benzoic Acid, but some evidence suggests that in the presence of ascorbic acid and benzoic acid, citric acid may accelerate the production of benzene.
Therefore, the use of Sodium Benzoate and L-Ascorbic Acid and Citric Acid in the same cosmetic formulations should be avoided. All cosmetic products should undergo microbial testing to ensure the efficacy of any preservative system. INCI: Sodium Benzoate California Prop 65 Statement: The following statement is made in order to comply with the California Safe Drinking Water and Toxic Enforcement Act of 1986.
Can you use potassium sorbate and citric acid together?
Potassium Sorbate is mainly effective against yeast and mold. These two preservatives are often used together for a broad spectrum of protection. PS and SB function best in an acidic environment. Citric acid can be used to reduce the pH to the optimal range where they function best, typically 3.0 – 5.0.
At what pH does potassium sorbate work?
Abstract – Mould growth was modelled on fermented bakery product analogues (FBPA) of two different pH (4.5 and 5.5), different water activity (a(w)) levels (0.80-0.90) and potassium sorbate concentrations (0-0.3%) by using seven moulds commonly causing spoilage of bakery products (Eurotium spp., Aspergillus spp.
And Penicillium corylophilum). For the description of fungal growth (growth rates) as a function of a(w), potassium sorbate concentration and pH, 10-terms polynomial models were developed. Modelling enables prediction of spoilage during storage as a function of the factors affecting fungal growth. At pH 4.5 the concentration of potassium sorbate could be reduced to some extent only at low levels of a(w), whereas at pH 5.5 fungal growth was observed even by adding 0.3% of potassium sorbate.
However, this preservative could be a valuable alternative as antifungal in such bakery product, of slightly acidic pH, if a long shelf life has not to be achieved.
Does potassium sorbate clog pores?
