What is Potassium Sorbate (Sorbic Acid)?

INCI: Potassium Sorbate

Potassium sorbate is a water-soluble preservative generally regarded as safe (GRAS) worldwide. It is the inactive salt of sorbic acid. It becomes sorbic acid, its active form, when dissolved in water, at a low pH. Sorbic acid is very pH dependent. It's highly effective at the low pH levels (ie pH 3.0) and decreases effectiveness at higher pH levels up to 6.0. Given the dependency on the pH level, it would be wise to check the pH level of your end product before using.

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.

As sorbic acid, it is considered to be active against mould, 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 potassium sorbate is generally a food-grade preservative, we repackage as a cosmetic raw material and is for external use only. Its appearance is off-white, granular needles of 5mm approximate length with particle size of 20-40 mesh.

Recommended usage level: 0.1% to 0.2% ie 1g to 2g per 1kg of product.
