Diethylhexyl Carbonate

What is Diethylhexyl Carbonate?

Diethylhexyl Carbonate is a synthetic diester formed from carbonic acid and 2-ethylhexanol, appearing as a clear, odorless liquid. In cosmetics, it serves mainly as an emollient and solvent, particularly in skincare formulations like creams, lotions, and serums. It functions by lowering the viscosity of thicker oils and waxes, enabling easier application and a smooth glide across the skin. This ingredient mimics natural skin lipids to fill in surface imperfections, promoting a softer texture. Its volatile nature allows quick evaporation, delivering a light, dry-touch sensation without residue. Widely used in facial products, body lotions, and sunscreens, it enhances overall sensory appeal while supporting even distribution of active ingredients.
