Common Name(s): Propylene glycol stearate se,propylene glycol stearate se,cosmetic functional ingredient,established active
CAS Number: N/a
DESCRIPTION
What It Does: Provides emollient skin conditioning with spreading value determined by the acid-alcohol ester molecular components.
Why It's Used: Propylene glycol stearate se is selected for its c18 stearic ester — the c-chain length provides structured waxy emolliency with moderate occlusive film, which distinguishes propylene glycol stearate se from esters of adjacent chain lengths in the same polarity tier.
How It Works: Ester polarity controls spreading: branched short-chain fast dry; medium moderate spreading; long occlusive. ester c=o provides polar adhesion to skin.
