Common Name(s): Ethylhexyl acetoxystearate,ethylhexyl acetoxystearate,ethylhexyl ester,2-ethylhexanol emollient
CAS Number: N/a
DESCRIPTION
What It Does: Provides modified stearate emolliency with acetoxy functional group with the characteristic lightweight dry touch from the 2-ethylhexyl branched alcohol moiety reducing skin drag versus linear alcohol esters.
Why It's Used: Ethylhexyl acetoxystearate is selected for the 2-ethylhexyl ester pairing with acetoxy stearic — the branched c8 alcohol provides a dry, light skin feel while the acetoxy stearic chain determines spreading speed and occlusion level, together delivering modified stearate emolliency with acetoxy functional group.
How It Works: 2-ethylhexyl branch: reduced surface tension → faster spreading; branched chain → lower melting point (stays fluid) → reduced skin drag; acid chain length → spreading coefficient and occlusion level.
Typically Found In: Emollient formulas,skin care
