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.
