C11-14 ISOPARAFFIN.

Valuable / SOLVENT, VISCOSITY CONTROLLING

A branched-chain hydrocarbon that functions as a lightweight occlusive emollient and solvent in skincare formulations. This petroleum-derived ingredient forms a breathable film on skin to prevent moisture loss while providing enhanced spreadability and a silky, non-greasy finish.

emollient solvent viscosity controlling

Science

Creates a lightweight, non-permeable barrier on the skin surface through its bulky branched structure, reducing transepidermal water loss by trapping moisture within the stratum corneum while its low surface tension properties improve product spreadability
