CETEARETH-25: Premium Plant-Derived Emulsifier for Ultra-Stable O/W Formulations
HLB 15–17 · High-Tolerance · Global Compliance
Product Overview
NIKOO's Ceteareth-25 (INCI: *Ceteareth-25*, CAS 68439-49-6) is a plant-derived, non-ionic emulsifier engineered for superior oil-in-water (O/W) emulsion stability. With high ethylene oxide content (25 moles EO), this white waxy solid excels in creating heat-resistant, sensorially elegant formulations for luxury skincare, sunscreens, and high-pH products (e.g., hair dyes). Its unique molecular structure ensures exceptional tolerance to extreme pH, electrolytes, and temperature fluctuations
Key Features
1. Strong emulsifying ability, capable of emulsifying oils of various polarities. Low usage, high emulsification efficiency, and excellent emulsification performance. It is typically used in conjunction with CETETH6, with a total usage of 2%-4%.
2. The resulting emulsion has a glossy, smooth appearance. Chemicalbook easily develops significant viscosity and maintains viscosity stability.
3. Ability to tolerate a certain amount of electrolytes, acids, or bases, making this emulsifier pair versatile and adaptable for a wide range of formulations.
4. The resulting emulsion is highly stable and maintains stability over time.
Core Applications & Benefits
Triple-Action Performance
Extreme Formulation Tolerance: Stable in pH 2–12 and high-electrolyte systems (e.g., AHA serums, alkaline hair dyes) .
Synergy Optimization: Paired with Ceteareth-6 (HLB 10–12) for ultra-stable O/W emulsions using 30% less emulsifier load .
Sensory Excellence: Imparts non-greasy, velvety textures in anti-aging creams and serums.
Applications:
Ceteareth-25 is an emulsifier used as a leveling agent and retarder in the dyeing and printing industry, an emulsifier in the glass fiber industry, a component of chemical fiber spinning oils, an emulsifier in cosmetics and ointment production, and in the formulation of household and industrial cleaning agents. In the chemical fiber industry, it is a component of various chemical fiber spinning oils, providing excellent spinnability. In general industry, it is used as an emulsifier, exhibiting excellent emulsification properties for animal, vegetable, and mineral oils, resulting in highly stable emulsions. It can also be used in the formulation of household detergents, industrial cleaners, and metal cleaners. It is used as a wetting agent in the textile industry and as an emulsifier component in the pesticide industry.
| Sector | Key Products | Safe Dose |
| Luxury Skincare | O/W creams, anti-aging serums | ≤16% (leave-on) |
| High-pH Products | Hair dyes, depilatory creams | 3–8% |
| Sunscreens | Mineral SPF stabilizers | 2-5% |
| Baby Care | Gentle lotions | ≤3% (rinse-off) |
Optimized Protocols
- Oil Phase: Blend with Ceteareth-6 (3:1 ratio) at 75°C.
- Aqueous Phase: Dissolve in water/glycerin at 75°C.
- Emulsification: Combine phases under high shear; cool before adding actives.
⚠️ Critical Note: Test for dioxane residues quarterly; avoid pH <2.0
Storage & Handling
Conditions: 25°C max, ≤60% humidity, sealed/light-resistant containers
