Product Description
What Is Cetylstearyl Alcohol?
Usually obtained from natural sources such as palm oil, coconut oil, or animal fats, cetylstearyl alcohol (Cetearyl Alcohol) is a blend of cetyl alcohol (C16H34O) and stearyl alcohol (C18H38O). As an emulsifier, thickener, and stabilizer, it is commonly used in pharmaceuticals, cosmetics, and personal hygiene products. It appears as a white, waxy solid.
Preparation: Cetylstearyl Alcohol is usually produced by blending Cetyl Alcohol and Stearyl Alcohol in varying proportions, with a common ratio of 1:1. These alcohols are derived from natural fatty acids through hydrogenation. The mixture is then purified, crystallized, and processed into flakes or pellets for easy incorporation into formulations. It can also be produced by esterifying fatty acids and reducing the resulting esters to the corresponding alcohols.

User Asked Question:
Q: How does Cetylstearyl Alcohol differ from other alcohols, such as Cetyl Alcohol or Stearyl Alcohol?
A: The primary difference between Cetylstearyl Alcohol and other alcohols like Cetyl Alcohol or Stearyl Alcohol lies in their composition. Cetylstearyl Alcohol is a blend of Cetyl Alcohol (C16) and Stearyl Alcohol (C18), whereas Cetyl Alcohol is a single fatty alcohol (C16) and Stearyl Alcohol is a different one (C18). This combination of two alcohols provides enhanced stability and a smoother texture, making it especially useful in formulations where both thickening and emulsifying properties are needed.
