About
A lightweight hydrocarbon that improves slip and spread, with pretty low reactivity on skin.
C9-13 isoalkane is a branched hydrocarbon solvent and texture enhancer used to give products a dry, silky feel. As a relatively inert, high-purity hydrocarbon mixture, it has low skin reactivity and poor dermal absorption, though aerosolized exposure is less ideal. Overall it is closer to a low-risk sensory carrier than to a problematic solvent.
