What are the main characteristics of G-25 Glycereth-25?

G-25 Glycereth-25 is a nonionic surfactant polymerized from natural glycerin and ethylene oxide, with core features of excellent emulsifying and solubilizing, moisturizing and nourishing, chemical stability, and mild safety.

Detailed Description

G-25 Glycereth-25 (INCI name: Glycereth-25, CAS No.: 31694-55-0) is a high-performance nonionic surfactant with a unique molecular structure that combines polyhydroxy hydrophilic groups and polyoxyethylene chains. This "dual-hydrophilic" structure endows the product with excellent overall performance. It is produced from natural glycerin through a precisely controlled ethoxylation reaction, making it a green and environmentally friendly surfactant.

In practical applications, G-25 exhibits extremely high hydrophilic-lipophilic balance characteristics, effectively reducing oil-water interfacial tension. It has significant solubilizing and emulsifying effects on flavors, essential oils, and poorly soluble active ingredients, forming stable and fine dispersion systems. Meanwhile, its molecular structure has good affinity with the skin's natural moisturizing factors, effectively enhancing the moisturizing performance of formulations, leaving a smooth and non-sticky feel after use.

In addition, this product is highly adaptable—maintaining stable performance over a wide pH range, tolerating acids, alkalis, and electrolytes, and resisting interference from calcium and magnesium ions in hard water, ensuring formulation reliability under different water conditions. As a nonionic surfactant, it has extremely low skin and eye irritation. The rat oral LD50 is greater than 5000 mg/kg (practically non-toxic), and the 28-day biodegradation rate exceeds 60%, in line with the development trend of modern green chemistry.

Technical Parameters

Application Recommendations

Based on the comprehensive performance characteristics of G-25, the following application directions are mainly recommended:

• Personal Care & Cosmetics: As a high-efficiency solubilizer for transparent makeup removers, perfumes, and serums; as an O/W emulsifier for light lotions and creams; as a moisturizing additive for rinse-off products such as shampoos and body washes to enhance post-wash hydration.
• Textile Industry: As a key component of spin finishes for synthetic fibers, providing antistatic and cohesion properties; as a softening agent in fabric finishing, imparting a fluffy and smooth hand feel.
• Metalworking Fluids: Serves as an emulsifier and lubricant in cutting fluids and grinding fluids, dissipating heat and extending tool life; its hard water resistance ensures stability of the working fluid under poor water quality conditions.
• Industrial Cleaners: As a low-foaming surfactant for high-pressure spray cleaning and hard surface cleaning, with strong wetting and penetrating ability, easy to rinse without residue.
• Emulsion Polymerization: Used as an emulsifier and stabilizer in the production of synthetic resins, coatings, and adhesives, helping to control latex particle size and improve product storage stability.
• Agrochemical Formulations: Used as an emulsifier and spreading agent for water-based pesticides, enhancing the wetting and spreading ability of the spray liquid on leaves.

Precautions

• Keep the container tightly closed during storage and place in a cool, dry, and well-ventilated area, away from incompatible substances such as strong oxidizers, strong acids, and strong alkalis.
• Avoid freezing and prolonged high-temperature exposure; storage temperature should be maintained within the range of 10°C to 40°C.
• When handling, it is recommended to wear impermeable gloves and chemical safety goggles to avoid prolonged or repeated skin contact.
• For specific physicochemical indicators, please refer to the Certificate of Analysis (COA); for detailed safety information, please refer to the Safety Data Sheet (SDS).
