Common Name(s): Acetyl ethylhexyl polyhydroxystearate,acetyl ethylhexyl polyhydroxystearate,cosmetic functional ingredient,specific formulation 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: Acetyl ethylhexyl polyhydroxystearate is selected for the c18 stearic–2-ethylhexyl ester pairing — combining structured waxy emolliency with moderate occlusive film with lightweight dry skin feel from branched chain to deliver the specific logp, spreading coefficient, and sensory signature engineered for the target skin feel profile.

How It Works: Ester polarity controls spreading (logp): branched short-chain (logp 5–7) → fast dry; medium chains → moderate spreading; long chains → occlusive. ester c=o provides polar adhesion.
