C10-40 ISOALKYL ACID OCTYLDODECANOL ESTERS.

Valuable CAS - / SKIN CONDITIONING, VISCOSITY CONTROLLING

A sophisticated ester complex engineered to replicate the branched-chain fatty acid structure naturally found in skin's lipid barrier and lanolin. This high-performance emollient delivers advanced skin conditioning while functioning as a structural enhancer in formulations, making it particularly valuable for barrier repair applications.

emollient viscosity controlling skin conditioning

Science

Integrates into the lipid matrix between corneocytes, mimicking natural iso-acids to strengthen barrier function and reduce transepidermal water loss. Simultaneously restores skin elasticity and provides non-aqueous viscosity enhancement for improved formulation stability.
