Science

Mechanism of Action

ETHYLENEDIAMINE/STEARYL DIMER DILINOLEATE COPOLYMER is a telechelic polymer designed to self-assemble, effectively forming clear-gel oil phases. Its inherent hydrophobicity allows it to create gels with low-polar liquids, including mineral oils, esters, and various emollients. Beyond its gelling capabilities, this copolymer acts as a film-former, lending water-repellent properties, and functions as an emulsion stabilizer, structuring agent, and wetting agent to maintain cosmetic product integrity and enhance skin feel. It also contributes to masking undesirable odors.
