Science
Mechanism of Action
Functioning as a mild anionic surfactant, Potassium Lauryl Phosphate acts as a detergent by reducing surface tension, enabling the efficient breakdown and removal of dirt, excess sebum, and environmental debris from the epidermal layer. Simultaneously, its emulsifying properties facilitate the stable integration of immiscible oil and water phases within a formulation, ensuring product uniformity, while also contributing to a pleasant, creamy lather and a soft post-rinse skin feel.

Safety
Safety Profile
The CIR Expert Panel concluded that alkyl phosphates, including Potassium Lauryl Phosphate, are safe for use in cosmetics when formulated to be non-irritating. While the raw material is classified by GHS to potentially cause skin irritation (H315) and serious eye damage (H318) at high concentrations (e.g., 77% paste), its irritation potential in properly diluted, formulated products is considered low, making it suitable for sensitive skin.
