Potassium Sorbate: A Safe and Effective Preservative for Cosmetics and Food

What is Potassium Sorbate?

Potassium Sorbate is the potassium salt of sorbic acid, a naturally occurring compound found in some berries. It is widely used as a preservative in the food, beverage, and cosmetic industries to inhibit the growth of mold, yeast, and bacteria, thereby extending product shelf life.

Known for its safety and broad-spectrum antimicrobial properties, Potassium Sorbate is one of the most popular preservatives in clean beauty and natural formulations.
