Cetearyl Alcohol

INCI: Cetearyl Alcohol | CAS #: 67762-27-0

Cetearyl alcohol is a fatty alcohol used in cosmetic formulations to build viscosity and stabilise emulsions in creams and lotions.

What is Cetearyl Alcohol & why is it used?

Cetearyl alcohol is used as a structuring agent to create stable emulsions and improve formulation consistency.

 

QUALITY MATTERS

Why specification quality matters

High-purity cosmetic grade cetearyl alcohol with controlled acid and hydroxyl values, supporting consistent formulation performance. 

 

Solubility Oil soluble
Primary function Thickener
Use level 2.0–5.0%

Behaviour in formulations

Cetearyl alcohol integrates into oil phases and provides structure and stability to emulsions.

Sensory notes

Cetearyl alcohol creates a rich, creamy texture with increased viscosity and body. It contributes to a more substantial skin feel compared to lighter structuring agents. Sensory outcome is formulation-dependent; bench testing is recommended.

 

Formulation considerations

PROCESSING

Add to oil phase and heat (~70°C) before emulsification.

COMPATIBILITY
  • Compatible with most cosmetic ingredients
  • Works best with emulsifier systems
  • Suitable across a wide range of formulations
pH
Not pH dependent
FORMULATION EXAMPLES

  • Oil phase: 5–15%
  • Water phase to 100% 

 Lotion system

  • Cetearyl alcohol: 2–3%
  • Emulsifier system
  • Emollients

Use level considerations

Recommended range 2.0–5.0%
Suggested starting level 3%%

Typically used at 2–5% in emulsion systems.

Formulation summary

Cetearyl alcohol is a core structuring ingredient used to create stable, well-balanced creams and lotions.

Quality notes
