Insufficient Data / SKIN CONDITIONING, SKIN CONDITIONING - EMOLLIENT

This synthetic polymeric ester functions as an advanced emollient and skin conditioning agent. It is engineered to impart a luxurious, cushioning feel to the skin, effectively combating dryness and leaving a soft, supple texture, reminiscent of 'melting butter' upon application.

Summary

Emollient Skin-conditioning agent

Science

Mechanism of Action

As a polymeric ester, STEARYL/PPG-3 MYRISTYL ETHER DIMER DILINOLEATE forms a sophisticated occlusive layer on the skin's surface, thereby enhancing moisture retention and softening the epidermal texture. This ingredient serves as a modern, synthetic alternative to traditional isopropyl lanolate, providing a distinct emollient and cushioning effect.
