Benzoic acid is the raw material for the production of sodium benzoate, which is a white, crystalline powder. It stops bacteria, yeast, and fungi from growing, which is why it's the most common preservative in cosmetics. Sodium benzoate is known to have a pH-dependent antimicrobial property and is water-soluble. Sodium benzoate for hair care products helps prevent bacterial and fungal growth.

Sodium benzoate, as a food, grade, and cosmetic, is a highly versatile product that is used not only in food preparations but also in skincare products, haircare products, and other personal care items. Sodium benzoate for skin is safe when used in limited amounts.
