Ceteareth-25 (CAS 68439-49-6) is a high-HLB non-ionic emulsifier with a higher degree of ethoxylation than Ceteareth-20, giving it strong hydrophilic character and excellent electrolyte tolerance — a preferred choice for sunscreen emulsions and light, stable lotions.
Physical & Chemical Properties
- INCI: Ceteareth-25
- Appearance: white to off-white waxy pellets or pastilles, no odor
- Solubility: dispersible/soluble in water; soluble in alcohol and oils when heated
- HLB value: approx. 16.3 (O/W)
- Ionic type: non-ionic
- Melting point: approx. 48–58°C
- Electrolyte tolerance: higher than Ceteareth-20, useful for salt-containing formulas
Key Benefits for Formulation
- Very high HLB: strong O/W emulsification for light, stable textures
- Excellent electrolyte tolerance: supports active-rich and salt-containing systems
- Sunscreen friendly: stabilizes UV filters and inorganic sunscreen dispersions
- Non-ionic & mild: low irritation potential for daily use
- Consistent performance: reliable batch-to-batch emulsification
Main Applications
- Sunscreens: stabilizes organic and inorganic UV filters
- Light lotions & fluids: elegant, fast-absorbing textures
- Active-rich serums & emulsions: tolerates salts and actives
- Body care: stable sprayable or pumpable emulsions
- Professional skincare: predictable viscosity control
