Sodium Benzoate
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.
