C13-16 Isoalkane

What C13-16 Isoalkane is & what it does

C13-16 Isoalkane is a lightweight synthetic hydrocarbon, a branched-chain isoalkane derived from petroleum or increasingly from plant sources. In a formula it acts mainly as an emollient and solvent, giving a dry, silky, fast-spreading slip without a heavy or greasy after-feel. It is often used as a volatile or low-viscosity carrier to thin out heavier oils and improve spreadability in sunscreens, creams, and color cosmetics. It is generally considered non-irritating and is valued for its clean, non-tacky skin feel.
