Valuable CAS 68037-64-9 / HAIR CONDITIONING, SKIN CONDITIONING, SURFACTANT - CLEANSING

PEG/PPG-28/21 ACETATE DIMETHICONE is a versatile silicone derivative engineered to enhance skin health and product performance. It functions as an emollient and skin conditioner, forming a protective barrier that reduces transepidermal water loss and shields against environmental stressors. This ingredient also acts as an effective emulsifier and can facilitate gentle cleansing.

Science

Mechanism of Action

This ingredient operates by establishing a non-occlusive protective film on the skin's surface, which effectively minimizes transepidermal water loss (TEWL) to maintain optimal hydration and prevent dehydration. This barrier simultaneously fortifies the skin's natural defenses, improving its resilience to external aggressors. Its amphiphilic structure also allows it to function as a surfactant, reducing surface tension within the stratum corneum and assisting in the dissolution and removal of impurities.
