GLYCERYL STEARATE DIMER DILINOLEATE COPOLYMER.

Valuable / SKIN CONDITIONING

A specialized copolymer, Glyceryl Stearate Dimer Dilinoleate Copolymer functions primarily as an emollient and skin conditioning agent, enhancing skin hydration and comfort. It also acts as a viscosity controller and emulsifier, stabilizing oil-rich formulations and providing a smooth, non-greasy finish.

Science

Mechanism of Action

This copolymer operates by forming a soft, flexible film on the skin's surface, which significantly improves hydration by reducing transepidermal water loss. Its emulsifying and stabilizing properties enable it to effectively blend oil and water phases in formulations, creating stable, smooth textures. It also contributes to a silky, non-greasy sensory experience while helping to control product viscosity.

Not reviewed
Sensitization risk Low

While this specific copolymer has not been individually reviewed by the Cosmetic Ingredient Review (CIR) Expert Panel, related Glyceryl Diester and Dimer Dilinoleate ingredient groups are considered safe for cosmetic use. CIR reports indicate related dimer dilinoleate ingredients are used in concentrations up to 53% in certain products like lipsticks. Clinical data on related compounds generally indicates a low risk of irritation or sensitization, though an isolated report of sensitization to dilinoleic acid (a component) has been noted. Component diglycerides are FDA-approved for use as indirect food additives.
