C11-15 ALKANE/CYCLOALKANE.

Valuable / SOLVENT

A lightweight hydrocarbon emollient that delivers superior spreadability and absorption without residual greasiness. This volatile solvent creates an elegant sensory experience while forming a protective barrier to minimize water loss from the skin surface.

solvent emollient

Science

Functions by reducing formula viscosity to enhance application properties, then evaporates or absorbs to leave a thin occlusive layer that prevents transepidermal water loss while maintaining a non-greasy finish on skin.
