Potassium Sorbate
What is it?
A salt of sorbic acid widely used as a mild preservative in cosmetics, particularly in formulations for infants and sensitive skin.
What does it do?
According to PubMed, a 2024 study analyzing preservative trends in infant and sensitive-population cosmetics found sorbic acid/its salts (including potassium sorbate) remain among the most prevalent traditional preservatives used, at concentrations within regulatory safety limits, though challenge testing showed product preservation could still be compromised under certain conditions regardless of preservative system -- real, current market-surveillance evidence for its established, comparatively gentle preservative role.
