POLYGLYCERYL-10 EICOSANEDIOATE/TETRADECANEDIOATE.

Valuable CAS 875112-30-4 / HAIR CONDITIONING, SKIN CONDITIONING

POLYGLYCERYL-10 EICOSANEDIOATE/TETRADECANEDIOATE is a sophisticated polyester, ingeniously engineered from polyglyceryl-10 and a blend of eicosanedioic and tetradecanedioic acids. Its distinctive structure, with alternating hydrophilic and hydrophobic segments, allows it to function as an exceptional skin conditioning agent. It visibly enhances hydration and imparts a silky, non-greasy finish.

Science

Mechanism of Action

This polyester leverages its unique polymeric structure, featuring both hydrophilic and hydrophobic groups, to operate as a multi-functional skin conditioner. It acts as an emollient and humectant, significantly improving the skin's moisture retention capacity and reinforcing the barrier function to minimize transepidermal water loss (TEWL). This action maintains optimal hydration of the stratum corneum for prolonged periods. Furthermore, it refines formulation aesthetics by mitigating greasiness and stickiness, and can facilitate enhanced penetration of co-formulated active ingredients.
