Science
Mechanism of Action
This ingredient functions primarily as a non-ionic water-in-oil emulsifier, effectively blending immiscible oil and water phases to create stable cosmetic formulations. As a surfactant, it reduces surface tension, improving product spreadability and distribution on the skin. Furthermore, its linseed oil derivation enriches formulations with beneficial fatty acids, contributing to skin conditioning, enhanced barrier function, and a desirable emollient feel.
