Key benefits

  • Builds formulation structure
  • Stabilises emulsions
  • Improves viscosity
  • Supports cream systems

Behaviour in formulations

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

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

Use level considerations

Use Rate (Min): 2.0
Use Rate (Max): 5.0

  • Emulsions: 2–5%
  • Used as structuring co-emulsifier

Starter Use Rate: 3%

Typically used at 2–5% in emulsion systems.

Formulation summary
