Common Name(s): Ethylhexyl isostearate,ethylhexyl isostearate,cosmetic functional ingredient,established active

CAS Number: N/a

DESCRIPTION

What It Does: Provides emollient conditioning with spreading value determined by the ester molecular architecture.

Why It's Used: Ethylhexyl isostearate 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: acid chain → emolliency type; alcohol chain → spreading speed and skin feel.

Typically Found In: Cosmetic formulations
