G-25 (Glycereth-25, INCI: Glycereth-25) is a high-performance nonionic surfactant produced by polymerizing natural glycerin with ethylene oxide. It possesses multiple functions including emulsifying, solubilizing, moisturizing, dispersing, and lubricating. The following sections describe its applications by industry based on product data from Guoli Chemical.
| Industry | Process/Use | Function/Role |
|---|---|---|
| Cosmetics & Personal Care | Creams, lotions, makeup removing oils, facial cleansing gels, transparent makeup remover water, skin care serums, perfumes | O/W emulsifier, high-efficiency solubilizer, moisturizing additive |
| Textile Industry | Synthetic fiber spinning oil, fabric finishing | Antistatic agent, softener, imparting smooth and soft feel to fabric |
| Metalworking Fluids | Water-based metal cutting fluids, grinding fluids, hydraulic fluids | Emulsifier, lubricant, reducing friction, protecting tools |
| Industrial Cleaners | High-pressure spray cleaning, immersion cleaning of hard surfaces (metal, glass, plastic) | Low-foam wetting agent, penetrant, solubilizer |
| Emulsion Polymerization | Synthetic resins, coatings, adhesives emulsion polymerization | Emulsifier, stabilizer, controlling latex particle size |
| Pesticide Formulations | Water-based pesticides (EC/EW/ME and other formulations) | Emulsifier, spreading agent, enhancing wetting and spreading ability |
G-25 has a very high HLB value, making it particularly suitable for O/W emulsion systems and solubilizing poorly soluble active ingredients (fragrances, essential oils). The recommended dosage in personal care is typically 0.5%-5%, while in industrial formulations it should be adjusted according to system requirements. Its nonionic nature makes it stable over a wide pH range, and it is resistant to hard water and electrolytes, offering excellent compatibility.
