Science
Mechanism of Action
This ingredient works on the skin by forming a light, protective film that effectively minimizes transepidermal water loss (TEWL), thereby improving moisture retention and skin hydration. Within cosmetic formulations, it acts as a plasticizer, glossing agent, and lubricant, facilitating smoother application and providing a non-tacky, comfortable skin feel.

Safety Profile
The CIR Expert Panel determined Diisostearyl Adipate to be safe for use in cosmetic products at current practices and concentrations, including maximum reported 'as used' concentrations of 10% in lipstick and 3% in skin cleansing products. While a concern was noted regarding dermal penetration data for long-chain, branched diesters, this did not alter the overall conclusion of safety.
