cetearyl alcohol CAS NO.67762-27-0

Cetearyl Alcohol (CAS No. 67762-27-0) is a widely used fatty alcohol blend consisting predominantly of cetyl and stearyl alcohols. As a mixture, it does not have a single defined molecular formula or molecular weight; however, its typical composition corresponds to a blend of C₁₆H₃₄O (cetyl alcohol) and C₁₈H₃₈O (stearyl alcohol), with an average molecular weight in the range of 240–270 g/mol.

1.MECHANISM OF ACTION

Cetearyl Alcohol primarily functions as an emulsifier, stabilizer, and viscosity enhancer in formulations. It works by interacting with both water and oil phases to form stable emulsions, while also providing a smooth, creamy texture and improving product spreadability and skin adherence.

2.PRODUCT INDICATIONS

This ingredient is extensively used in cosmetic and pharmaceutical products, including creams, lotions, hair conditioners, ointments, and moisturizers, to impart emollient properties, enhance texture, and stabilize formulations without causing skin irritation.

3.CLINICAL EFFICACY OF PRODUCT

Cetearyl Alcohol is recognized for its safety and efficacy in improving skin hydration, barrier function, and product stability. It is non-comedogenic, hypoallergenic, and widely supported by dermatological studies as a well-tolerated excipient in topical formulations
