C13-14 Isoparaffin belongs to a group of isoparaffinic hydrocarbons. These are made by refining petroleum and separating out molecules with 13 to 14 carbon atoms. Their branched shape keeps them liquid at room temperature and gives them a light, clear feel.

Formulators use it because it spreads easily and leaves little residue, so it can make a rich cream feel lighter. It shows up often in moisturizers, sunscreens and acne products, where a non-greasy finish matters. It has a very mild or almost no odor and does not usually feel sticky.
