It has excellent lubricity, moisturizing, dispersion and adhesion. It can be used as antistatic agent and softener in cosmetics, pharmaceuticals, chemical fibers, rubber, plastics, papermaking, paints, electroplating, pesticides, metal processing and food. It has a wide range of applications in processing and other industries.
Product introduction
Polyethylene glycol often shortened to PEG, is a polymer composed of repeating glycol diether units. Its molecular formula is H O(CH2CH2O)nH, where n represents the degree of polymerization, that is, the number of ethylene glycol pairs in the molecular chain. The molecular weight of polyethylene glycol can vary from a few hundred to several million, depending on its degree of polymerization.
Its emollient, hygroscopic and softening properties are of particular interest. Polyethylene glycol can be used alone, but is more often used in combination with other bases. It has entered various creams, detergents, pastes, and viscous liquids.

Product application
Polyethylene glycol itself and its fatty acid esters are also widely used in cosmetics. Its emollient, hygroscopic and softening properties are of particular interest. Polyethylene glycol can be used alone, but more often it is used in combination with other base materials. It has found its way into various greases, detergents, pastes, viscous liquids, cake salts and powders.
Examples: Cream, powder-based cosmetics, beard cream, toothpaste, hair dye, conditioner, shampoo, toilet detergent, skin cleanser, deodorant, sticky perfume, rouge and eyebrow oil, etc.
Packaging & Storage
1. Polyethylene glycol substances should be avoided from being mixed with flammable, explosive and other dangerous goods during transportation;
2. The packaging box must be marked with the name, concentration, molecular weight and other information of polyethylene glycol;
3. Hazard signs and labels should be placed on the exterior and interior of the vehicle so that safety personnel can handle them promptly when needed.
