Common Name(s): Acetylated glycol stearate,glyceryl/glycol ester or ether,emollient emulsifier

CAS Number: N/a

DESCRIPTION

What It Does: Provides emollient skin conditioning, mild emulsification, and moisture retention from the glyceryl ester or ether structure.

Why It's Used: Glycerol esters and ethers provide versatile multi-functional emolliency and emulsification — the glycerol backbone's multiple oh groups enable diverse esterification and etherification for formulation-specific performance.

How It Works: Glycerol ester/ether: glycerol backbone provides hydrophilicity; fatty acid ester or alkyl ether chains provide lipophilicity. the balance determines hlb and function — mono-esters provide emolliency and co-emulsification; di/tri-esters provide pure emolliency.

Typically Found In: Emulsions,skin care
