C12-15 ALCOHOLS.

Valuable CAS 63393-82-8 / EMULSION STABILISING, SKIN CONDITIONING - EMOLLIENT, VISCOSITY CONTROLLING

C12-15 Alcohols are long-chain fatty alcohols that serve as multifunctional emollients and texture enhancers in skincare formulations. These versatile ingredients smooth skin texture while providing structural integrity to creams and lotions through their emulsion-stabilizing properties. Their mild occlusive action helps reinforce the skin barrier without heavy residue.

Summary

emollient viscosity controlling emulsion stabilising

Science

Mechanism of Action

Functions as an emollient by filling intercellular gaps to create smoother skin texture, while simultaneously strengthening the interfacial film in oil-in-water emulsions. Provides mild occlusive properties that help reduce transepidermal water loss by reinforcing the lipid barrier matrix.
