Cetyl Alcohol – Classic Cosmetic Emulsifier & Thickener
✅ Cetyl Alcohol is one of the oldest known long-chain fatty alcohols. Commonly found in shampoos, creams, and lotions, it is primarily used as an opacifier, emulsifier, and thickening agent. It enhances product viscosity, stabilizes foams, and improves formulation aesthetics.
✅ Due to its water-binding properties, cetyl alcohol functions as a powerful emollient, helping prevent skin dryness and chapping.
✅ Cetyl Alcohol is widely used for viscosity control in oil-in-water (O/W) emulsions in both cosmetic and pharmaceutical applications. It appears as a white, hydrophilic wax in pellet form.
✅ Technical Information
- Hydroxyl Value: 228–234
- Hydrocarbon Content: Max. 0.5%
- Solidification Point: 47–50°C
- INCI Name: Cetyl Alcohol
- CAS Number: 36653-82-4
✅ Origins & Naming
Also known as hexadecan-1-ol or palmityl alcohol, cetyl alcohol is a C-16 fatty alcohol. At room temperature, it appears as white waxy pellets. Its name originates from “cetacea oil” — whale oil — from which it was first extracted.
✅ Uses & Benefits
- Emollient: Softens and protects skin.
- Emulsifier: Maintains even distribution of oil and water ingredients.
- Thickener: Enhances the viscosity and body of creams and lotions.
- Foam Stabilizer: Boosts foam volume and stability in cleansing products.
- Adherence Agent: In lipsticks, helps pigment adhere to lips without melting easily.
- Food-Grade Use: Recognized by FDA as safe for use in food additives and decorations.
✅ Regulatory & Safety
According to the FDA Code of Federal Regulations, cetyl alcohol is safe for use in food and in the synthesis of food components. It is also listed as an OTC skin protectant for treating irritations from poison ivy, oak, sumac, insect bites, and more.
✅ FAQ: What’s the Difference Between Cetyl Alcohol and Cetearyl Alcohol?
Cetearyl alcohol is a blend of cetyl alcohol and stearyl alcohol. Both are fatty alcohols and offer similar benefits, but cetearyl has a slightly higher melting point and more waxy texture — making it ideal for firmer or thicker product formulations.
A staple in skincare science — cetyl alcohol offers functionality, comfort, and cosmetic elegance in every application.
