Common Name(s): Emollient ester,skin conditioning lipid,texture modifier

CAS Number: N/a

DESCRIPTION

What It Does: Provides emollient skin conditioning with specific spreading and sensory properties determined by the alcohol and acid components of the ester.

Why It's Used: Ester emollients are selected for their specific spreading value (from polar and non-polar components), skin feel, and formulation compatibility — replacing mineral oil with cosmetically elegant plant-derived lipid chemistry.

How It Works: Ester formation: fatty acid + alcohol → ester + h₂o. the ester's physicochemical properties (viscosity, spreading value, polarity) are determined by the acid chain length/saturation and the alcohol type — enabling precise sensory engineering through ester selection.

Typically Found In: Skin care,colour cosmetics

Avoid Combining With: No significant incompatibilities

SCIENTIFIC NOTE

Spreading value (inverse of viscosity × surface tension) determines skin feel: low-spreading esters (heavy, rich) → moisturisers; high-spreading esters (light, silky) → tonics and serums. ester selection matched to product texture target.
