IsododecaneBarrier
A light, volatile emollient that spreads thin and then evaporates, leaving a weightless finish — common in long-wear and primer-type products.
What it does
Isododecane is a volatile hydrocarbon emollient: it gives an ultra-light, fast-spreading slip and then evaporates, so the finish feels weightless. That makes it popular in long-wearing, transfer-resistant, and primer textures. It conditions the surface briefly and is a feel ingredient rather than an active.
