Potassium sorbate (K-sorbate) is a potassium salt of sorbic acid, which is considered as an effective preservative in cosmetic and personal care products. It inhibits the growth of microorganisms, mould, bacteria and yeast and is considered safe for most people when used in appropriate concentrations. Potassium sorbate can be found in skincare, makeup, haircare and in food and beverages.

Potassium sorbate is generally considered as safe, as it harmlessly metabolizes into water and carbon dioxide. However, it may cause skin irritation in some individuals with sensitive skin.
Potassium sorbate works by binding to the sulfhydryl groups of microbial enzymes, disrupting their enzyme systems and inhibiting essential metabolic processe.Â
Potassium Sorbate is made by neutralizing sorbic acid with potassium hydroxide. It also naturally found in Rowan berries (Sorbus aucuparia).
Potassium sorbate is considered vegan as it synthesised from sorbic acid and potassium hydroxide reaction ands it does not involve any animal products or testing.Â
