C12-13 ALCOHOLS.

Valuable CAS 75782-86-4 / EMULSION STABILISING, SKIN CONDITIONING - EMOLLIENT, VISCOSITY CONTROLLING

C12-13 Alcohols represent a blend of fatty alcohols that serve as multifunctional skin conditioning agents in cosmetic formulations. These saturated chain alcohols excel at smoothing skin texture while providing essential emulsion stabilization and viscosity control. Their versatile nature makes them valuable components across diverse product categories from moisturizers to cleansers.

Summary

viscosity controlling emulsion stabilising emollient

Science

Mechanism of Action

Functions as an emollient by integrating into intercellular spaces to create a smoother skin surface and enhance moisture retention. Simultaneously acts as a viscosity modifier and emulsion stabilizer, maintaining product consistency and extending formulation shelf-life through its structural properties.
