Science
Mechanism of Action
This ingredient operates primarily as a skin conditioning agent, providing significant emollient and lubricating properties. By forming a protective film on the skin's surface, it improves the spreadability and glide of topical formulations while imparting a distinctively smooth and velvety feel. Furthermore, Isostearyl Sebacate is understood to enhance skin barrier function, thereby optimizing its inherent water-holding capacity and effectively reducing transepidermal water loss to prolong hydration.

Stability
No specific optimal pH range for Isostearyl Sebacate's stability has been identified. However, as an ester of sebacic acid, it may be susceptible to hydrolysis when exposed to extreme pH conditions. Cosmetic formulations are generally designed to maintain a pH between 4.0 and 6.0 for optimal product integrity and skin health.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) expert panel has concluded that Isostearyl Sebacate is safe for use within the parameters of current cosmetic practices and concentrations. It is important to note that this safety assessment is primarily based on the maximum reported 'as used' concentrations, indicating a potential absence of comprehensive data for higher concentrations. No specific safety opinion from the Scientific Committee on Consumer Safety (SCCS) has been found.
