Science
Mechanism of Action
This ingredient operates by lowering the interfacial tension between immiscible liquids, such as oils and water. With an approximate hydrophilic-lipophilic balance (HLB) of 8, it is particularly effective in forming stable oil-in-water emulsions. This action allows for the even dispersion of oil components within an aqueous base, facilitating its role in gentle cleansing and makeup removal.

Safety
Safety Profile
Comprehensive safety assessments from the Cosmetic Ingredient Review (CIR) or the Scientific Committee on Consumer Safety (SCCS) specifically for Polyglyceryl-2 Sesquicaprylate in cosmetic applications are not readily available. While the FDA does not pre-approve cosmetic ingredients (excluding color additives), and some related polyglycerol esters are deemed Generally Recognized As Safe (GRAS) for food uses, this does not directly confirm its safety for cosmetic use.

Verdict
Polyglyceryl-2 Sesquicaprylate is a valuable, gentle emulsifier and cleanser compatible with all skin types, yet its overall safety profile for cosmetic use requires further comprehensive assessment from regulatory bodies.
