Science

Mechanism of Action

Operating as an esterquat, a biodegradable cationic surfactant, DIOLEOYLAMIDOETHYL HYDROXYETHYLMONIUM METHOSULFATE adheres to negatively charged surfaces of hair and skin. This interaction creates a smooth, protective film, thereby delivering conditioning, smoothing, and anti-static benefits. It also supports 'moisturizing - structure replenishing' processes, enhancing the overall feel and integrity of the treated surface.

Stability

This ingredient maintains stability within a pH range of 3.5 to 7.0. As a yellow liquid prone to precipitation, it requires shaking prior to use. It readily integrates into the water phase, with gentle heat (below 80°C) potentially aiding dissolution. If haziness or separation occurs, homogenization at 35-40°C may be required.
