Science
Mechanism of Action
As an anionic surfactant, Potassium Laurate primarily acts by significantly reducing the surface tension of liquids, thereby enhancing their wetting capabilities and facilitating the formation of stable emulsions and luxurious foam. This mechanism supports effective removal of impurities and aids in product stabilization. Furthermore, research indicates its capacity for antimicrobial activity and its role as a humectant-like agent, helping to retain skin moisture and mitigate potential post-cleanse dryness.

Stability
Potassium Laurate demonstrates optimal performance in alkaline environments, specifically within a pH range of 9.0 to 11.0, with peak foam stability observed between pH 9.0 and 10.0. To ensure integrity, formulations should avoid exposure to temperatures exceeding 80°C and be stored in cool, dry conditions away from moisture. While it possesses a potential for mild drying, this can be effectively counteracted through strategic co-formulation.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel concluded that Potassium Laurate is safe for use in current cosmetic practices at concentrations ranging from 0.001% to 9%, provided the final product is formulated to be non-irritating and non-sensitizing. It is also recognized as Generally Recognized As Safe (GRAS) by the FDA when used as a food additive.
