Potassium Sorbate

Forms sorbic acid when dissolved in water and is the most widely used food grade preservative. It is effective up to pH 6.5, but is more effective as the pH decreases and becomes more acidic. Potassium sorbate is effective against yeasts, molds, and some bacteria. It is used in the food industry from 0.025 to 0.10%. Can be used to increase the pH in formulations. 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.

Potassium sorbate is not a broad spectrum preservative for cosmetic use. All cosmetic products should undergo microbial testing to ensure the efficacy of any preservative system.
