Description
Potassium sorbate (E202) is the potassium salt of sorbic acid, registered under CAS 24634-61-5 and EC 246-376-1. It is commercially available under trade designations including PO 300 and K 60/95, and carries FEMA number 2921. The compound is approved as a food additive under E-number E202 across EU and international markets.
In food and beverage manufacturing, E202 inhibits mold, yeast, and bacterial growth by disrupting microbial cell membrane function and enzyme activity, extending shelf life in products such as baked goods, dairy, and beverages. In personal care formulations, it serves as a preservative and skin conditioner, functioning effectively at low concentrations within a defined pH range.
Potassium sorbate is supplied in powder form and is available in food-grade (FCC), cosmetic-grade, and Ph.Eur.-compliant specifications. It falls under HS code 29161900 and is subject to REACH registration requirements within the European Union.
