PEG600MO is a nonionic surfactant prepared by esterification of polyethylene glycol 600 with natural oleic acid, appearing as a pale yellow to yellow liquid or paste. Its molecular structure combines hydrophilicity and lipophilicity, with a moderate HLB value, enabling it to form a stable interfacial film at the oil-water interface, making it an ideal choice for preparing O/W emulsion systems. The product remains stable over a wide pH range and under hard water conditions, and shows good compatibility with anionic, cationic, and amphoteric surfactants.
In various industries, the core functions of PEG600MO manifest in the synergistic effects of five aspects: emulsification, solubilization, wetting, dispersing, and lubrication. In personal care products, it serves as an emulsifier for creams and lotions and as a solubilizer for cleansing oils; in the textile industry, it is used for fiber finishing to reduce friction coefficient; in metalworking fluids, it provides emulsion stability and boundary lubrication; in agrochemical formulations, it promotes uniform dispersion of active ingredients and wetting of targets; in industrial cleaning, it enhances the removal of oily soils; in the pharmaceutical field, it improves the solubility and bioavailability of poorly soluble drugs.
Derived from natural fatty acids, this product is relatively mild and low-irritating, making it particularly suitable for formulations requiring high skin-friendliness. According to GHS classification, this substance falls under Skin Irritation Category 2, Eye Irritation Category 2A, and Respiratory Irritation Category 3, requiring appropriate protective measures during handling.
