Polyethylene Glycol 4000 is a general term for ethylene glycol polymers containing alpha, ω-double-terminated hydroxyl groups.
CAS No.: 25322-68-3
Polyethylene Glycol 4000 is a kind of high polymer, chemical formula is HO(CH2CH2O)nH, non-irritating, slightly bitter taste, has good water solubility, and many organic components have good compatibility. With excellent lubricity, moisture, dispersion, adhesion, can be used as an antistatic agent and softening agent, etc., in cosmetics, pharmaceuticals, chemical fiber, rubber, plastics, paper, paint, electroplating, pesticides, metal processing and food processing industries have a very wide range of applications.
Main use
Polyethylene glycol and polyethylene glycol fatty acid ester are widely used in cosmetics industry and pharmaceutical industry. Because polyethylene glycol has many excellent properties: water solubility, non-volatility, physiological inertia, gentleness, lubricity and make the skin wet, soft, pleasant after use. Polyethylene glycol with different relative molecular weight grades can be selected to change the viscosity, hygroscopicity and structure of the product. Low molecular weight polyethylene glycol (Mr< 2000) Suitable for use as a wetting agent and consistency regulator, used in creams, lotions, toothpastes and shaving creams, etc., also suitable for unwashed hair care products, giving hair a filamentous shine. High molecular weight polyethylene glycol (Mr> 2000) For lipstick, deodorant stick, soap, shaving soap, foundation and beauty cosmetics. In cleaning agents, polyethylene glycol is also used as a suspension agent and a thickener. In the pharmaceutical industry, it is used as a base for ointments, emulsions, ointments, lotions and suppositories.
Polyethylene Glycol 4000 is widely used in a variety of pharmaceutical preparations, such as injectable, topical, ocular, oral, and rectal preparations. Solid grade polyethylene glycol can be added to liquid polyethylene glycol to adjust the viscosity for local ointment; Polyethylene glycol mixture can be used as suppository substrate. The aqueous solution of polyethylene glycol can be used as a suspension aid or to adjust the viscosity of other suspension media. The combination of polyethylene glycol and other emulsifiers increases the stability of the emulsion. In addition, polyethylene glycol is also used as film coating agent, tablet lubricant, controlled release material, etc.
