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.

It works against a wide range of fungi, yeasts, and some bacteria, making it versatile across different product types.

3. Mild and Non-Irritating

Compared to other preservatives like parabens, Potassium Sorbate is generally well-tolerated and has a low potential for skin irritation, making it suitable for sensitive skin products.

4. Compatible with Various Formulations

Derived from natural sources, it fits well within clean beauty, organic, and natural product standards, appealing to health-conscious consumers.
