Sodium Sorbate
What is Sodium Sorbate?
Sodium sorbate is the sodium salt of sorbic acid, a naturally occurring compound found in certain berries like rowanberries, though commercially produced via synthesis for purity and consistency. In cosmetics, it functions mainly as a preservative in aqueous formulations such as lotions, creams, gels, and toners. It works by interfering with the metabolic processes of fungi, yeasts, and select bacteria, preventing their proliferation and thus avoiding product spoilage or contamination risks. This mechanism helps preserve the formulation's integrity over time. Approved for use in cosmetics by regulatory authorities, it is effective at typical inclusion levels and contributes to maintaining hygienic standards without altering product texture or efficacy. Its role is essential in multi-use containers where repeated exposure to air and hands can introduce contaminants.
