General Description
NANOGREEN C25, also known as Ceteareth-25, is a non-ionic surfactant and emulsifier derived from fatty alcohols (cetyl and stearyl alcohols) that have been ethoxylated. It appears as a white to off-white waxy solid or flakes and is valued in the cosmetic industry for its ability to stabilize oil-in-water emulsions. With excellent emulsifying and solubilizing properties, NANOGREEN C25 is widely used in creams, lotions, hair care products, and other personal care formulations where a smooth and stable texture is essential.
Uses in the Cosmetics Industry
NANOGREEN C25 plays a crucial role in a wide range of formulations:
- Creams & Lotions: Works as a primary emulsifier to stabilize oil and water phases, ensuring consistent product texture.
- Hair Conditioners & Treatments: Helps in dispersing oils and conditioning agents evenly for smooth application.
- Facial Cleansers: Improves solubility of oils and active ingredients while maintaining product stability.
- Makeup & Sunscreens: Acts as an emulsifier to achieve uniform blending of ingredients for consistent coverage.
- Shampoos & Body Washes: Enhances solubilization of fragrances, essential oils, and actives for clear formulations.
Its versatility and compatibility with a wide range of oils and actives make NANOGREEN C25 a preferred choice for manufacturers looking to create high-performance emulsions.
Hazards
While NANOGREEN C25 is widely regarded as safe when used within recommended cosmetic concentrations, certain precautions should be noted:
- Skin Irritation: Rare, but in high concentrations it may cause mild irritation, especially on sensitive skin.
- Eye Irritation: Direct contact with undiluted material may cause temporary irritation.
- Ethoxylation Residues: As with other ethoxylated ingredients, trace impurities (e.g., 1,4-dioxane) may be present if not properly purified; sourcing from reputable suppliers minimizes this risk.
- Environmental Impact: Considered biodegradable but should still be handled responsibly in large-scale manufacturing.
Proper formulation practices and adherence to regulatory concentration limits ensure safe use of NANOGREEN C25 in cosmetic products.
Storage & Stability
- Storage: Store in a tightly sealed container in a cool, dry environment, away from excessive heat and moisture.
- Stability: Stable in both acidic and alkaline formulations, maintaining emulsifying properties across a broad pH range.
NANOGREEN C25 is available in bulk and wholesale for industrial and cosmetic manufacturing, ensuring consistent quality and performance in emulsions and formulations.
