C9-11 Isoparaffin
What is C9-11 Isoparaffin?
C9-11 Isoparaffin is a mixture of branched, saturated hydrocarbons containing 9 to 11 carbon atoms, produced via petroleum distillation and purification processes. It falls under emollients and solvents in cosmetic formulations, appearing in makeup like foundations and primers, skincare moisturizers, and hair care items such as conditioners. Chemically inert and volatile, it solubilizes diverse actives—polar and non-polar—enabling clear, homogeneous blends without altering pH. As a viscosity modifier, it fine-tunes flow properties, preventing separation and improving pumpability. Upon application, its low viscosity promotes even spreading, followed by rapid evaporation that minimizes residue, delivering a silky, breathable feel ideal for oil-free textures.
