THE STORY OF NANOGREEN C25
Nanogreen C25: High-HLB Emulsifier for Smooth, Stable Creams & Gels
Ceteareth-25 is a non-ionic, high-HLB emulsifier used to create stable oil-in-water (O/W) creams, lotions, cleansers, and hair systems. Known for producing light, elegant textures with good foaming and rinseability, it is commonly used in skincare, haircare, and cleansing emulsions.
Ethoxylated Blend of Cetyl & Stearyl Alcohols for High Stability
Nanogreen C25 is produced by ethoxylating a mixed fatty alcohol base (C16–C18) with an average of 25 moles of ethylene oxide. The result: a high-HLB (approx. 16) O/W emulsifier with excellent solubility, consistency control, and compatibility with various oils, silicones & actives.
Emulsify. Solubilize. Stabilize.
Key formulation advantages:
✅ Creates stable O/W emulsions with light, non-greasy feel
✅ Improves solubilization of oils, silicones & fragrance
✅ Supports foaming and rinse-off performance in cleansers
✅ Works synergistically with fatty alcohols & co-emulsifiers
✅ Allows high-viscosity product structuring without waxy skin drag
Used in: moisturizers, hair conditioners, leave-on lotions, styling creams, cleansing milks, shave foams, and color cosmetics.
