C10-12 ISOPARAFFIN.

Valuable / SOLVENT, VISCOSITY CONTROLLING

A lightweight hydrocarbon mixture that delivers exceptional emollience without the greasy feel typical of heavier emollients. This branched-chain molecule creates a breathable barrier that locks in moisture while maintaining skin's natural texture and comfort.

Science

Forms a semi-occlusive film on the skin's surface that reduces transepidermal water loss while filling microscopic gaps between corneocytes. Its unique molecular structure provides immediate smoothing effects and enhances product spreadability without compromising skin breathability.
