Sodium sorbate

Sodium sorbate (CAS 7757-81-5), also known commercially as E201, is the sodium salt form of sorbic acid used as a preservative in food and personal care products.

Where is Sodium sorbate used?

• Food manufacturing: preserves baked goods and dairy products
• Beverages and processed foods: suitable where pH-neutral or mildly alkaline conditions favor the sodium salt over sorbic acid
• Wine and fruit-based products: prevents refermentation without significantly altering taste profiles
• Personal care: preservative in creams, lotions, and wet wipes that performs effectively in higher-pH systems
• It inhibits the growth of mold, yeast, and bacteria, extending shelf life.

Good to know: Cosmetic manufacturers sourcing alternatives to parabens increasingly evaluate it as part of preservation systems.
