Overview
KPEG-350 is a polyethylene glycol (PEG) derivative with an average molecular weight of 350. It is widely used in various industries due to its excellent solubility, stability, and non-toxic nature. Polyethylene glycols like KPEG-350 are versatile chemicals, often employed as solvents, emulsifiers, and lubricants. Their biocompatibility makes them particularly valuable in pharmaceutical and cosmetic formulations.
Physical and Chemical Properties
KPEG-350 is a colorless to pale yellow viscous liquid with a mild odor. It has a density of approximately 1.1 g/cm³ and a melting point between 4-8°C. The compound is highly soluble in water and many organic solvents, including alcohols and glycol ethers. Its chemical stability under normal conditions and non-toxic nature make it suitable for a wide range of applications. The boiling point exceeds 250°C, though it may decompose at higher temperatures rather than boiling cleanly.
Main Applications
In the pharmaceutical industry, KPEG-350 serves as a solvent, excipient, and delivery vehicle for active ingredients. It's commonly found in ointments, creams, and liquid medications. The cosmetics industry uses KPEG-350 in personal care products like lotions and shampoos for its moisturizing properties. Industrially, it functions as a lubricant, plasticizer, and in textile processing.
Safety and Storage
KPEG-350 is generally regarded as safe with low toxicity. However, prolonged skin contact should be avoided as it may cause mild irritation. Proper ventilation is recommended when handling in enclosed spaces. For storage, keep containers tightly closed in a cool, dry area away from direct sunlight and moisture. The material is stable under normal conditions but may absorb water if exposed to humid environments.
B2B Procurement Guide
When procuring KPEG-350, verify the CAS number (25322-68-3) to ensure product authenticity. Check for certificates of analysis that confirm purity and molecular weight specifications. Consider ordering from suppliers with ISO certification or pharmaceutical-grade manufacturing capabilities if high purity is required. Bulk purchases typically offer better pricing, with common packaging options including 25kg drums or 200kg barrels.
