Cetyl Alcohol

Cetyl Alcohol is a fatty alcohol derived from natural sources, widely used in cosmetic formulations as a thickener, co-emulsifier, and emollient modifier. Despite its name, it is non-drying and non-irritating, functioning as a structural lipid rather than a volatile alcohol.

This ingredient plays a critical role in improving texture, stability, and skin feel, making it a foundational component in emulsions, creams, and conditioning systems.

Rheology & Structure Enhancement

• Increases viscosity and body of emulsions
• Improves formulation stability
• Enhances cream structure and consistency

Skin Feel & Sensory Modification

• Provides a smooth, velvety glide
• Reduces greasy or tacky feel
• Improves spreadability

Barrier Support (Secondary Function)

• Contributes to occlusivity
• Supports moisture retention
• Enhances emollient systems

Applications

• Creams and lotions
• Conditioners and hair masks
• Body butters
• Cleansing systems
• Emulsified serums

Recommended Usage Rate

• 0.5 – 5%

Formulation Notes

• Oil-phase ingredient
• Often paired with:
  • Glyceryl Stearate
  • Cetearyl Alcohol
• Higher levels increase viscosity and firmness

From the Chemist

Jennifer says…

“Cetyl Alcohol is one of those ingredients you don’t notice until it’s missing. It quietly controls texture, stability, and feel. If your emulsion feels thin or lacks structure, this is often part of the solution.”
