Science

Mechanism of Action

This ingredient functions as an emulsifying agent, adeptly blending water and oil phases to ensure smooth product consistency and prevent phase separation. As a surfactant, it effectively lowers surface tension, facilitating the removal of oil-based impurities from the skin and hair by enabling their suspension in water. It also acts as a solubilizer, integrating components that would typically not dissolve in liquids. Beyond these roles, OLETH-10 CARBOXYLIC ACID enhances overall formulation stability, improves efficacy in hard water, supports the penetration of other active ingredients, and is noted for its ability to soften the potentially harsh effects of stronger actives.
