Description

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
