POTASSIUM BENZOATE

Description

Potassium benzoate is a widely used preservative in the cosmetic and personal care industry, known for its efficacy in inhibiting the growth of bacteria, yeasts, and molds. This white, crystalline powder is the potassium salt of benzoic acid and is water-soluble, making it an ideal choice for various skincare formulations.

In skincare products, potassium benzoate typically functions at concentrations between 0.1% and 0.5%. It is particularly effective in formulations with an acidic pH, ideally below 4.5. This ingredient works synergistically with other preservatives, enhancing the overall preservation system of a product.

Potassium benzoate is generally considered safe for use in cosmetics by regulatory bodies worldwide, including the FDA and EU Cosmetics Regulation. It is non-sensitizing and non-irritating to the skin when used at recommended concentrations. However, individuals with salicylate sensitivities may need to exercise caution.

Beyond its preservative role, potassium benzoate can act as a corrosion inhibitor and pH adjuster in certain formulations. Its stability in the presence of light and heat makes it a reliable choice for a wide range of skincare products, including creams, lotions, and aqueous-based serums.
