CyclohexasiloxaneBarrier

A light, volatile cyclic silicone that gives a silky slip and evaporates without residue.

What it does

Cyclohexasiloxane is a volatile cyclic silicone, often used alongside cyclopentasiloxane. It carries other ingredients with a smooth, dry, silky slip and then evaporates, leaving a weightless finish. It is a feel-and-spreadability ingredient rather than an active.
