Benzoic Acid
Benzoic Acid
A mild preservative (also used in food) that protects formulas from yeast and bacteria, most effective at lower pH.
What it does
Benzoic acid and its salt sodium benzoate are gentle, widely accepted preservatives used in both food and cosmetics. They guard against yeast and some bacteria and work best in lower-pH formulas, so they are often paired with other preservatives for full coverage. The role is keeping the product safe over its shelf life.
