Sorbic Acid
A mild, widely accepted preservative (also used in food) that keeps products free of mold and yeast.
What it does
Sorbic acid, and its salt potassium sorbate, are gentle preservatives effective mainly against mold and yeast. They are used in food as well as cosmetics and are a common choice for formulas aiming at a mild preservative profile. Sorbic acid works best at lower pH and is often combined with other preservatives for full coverage.
