CAS 25322 -68-3 Poly (ethylene glycol)

Polyethylene glycol is abbreviated as "PEG", with an average molecular weight of 200-7000. Polyethylene glycol is widely used in the cosmetic and pharmaceutical industries. Used in creams, lotions, toothpaste and shaving cream, etc. Also suitable for non-rinsing hair care products.

1.Polyethylene glycol is widely used in various preparations, such as injection, local preparation, eye preparation, oral and rectal preparations.

2.Polyethylene glycol at the solid level can be added to the liquid polyethylene glycol to adjust the viscosity for local ointments.

3.Polyethylene glycol mixtures can be used as suppository matrix;

4.The aqueous solution of polyethylene glycol can be used as a suspension or to adjust the viscosity of other suspension media.

5.Polyethylene glycol and other emulsifiers are used to increase the stability of emulsion.

6.In addition, polyethylene glycol is also used as film coating agent, tablet lubricant, controlled release material and so on.
 

Use:

1.Used as solvent and moisturizing agent, also used to make plasticizer, medicine, polyester resin, polyurethane resin, etc.

2.Used as chromatographic analysis reagent, also used in organic synthesis.

3.solvent. Wetting agent. Intermediates of plasticizers. Crosslinking agent for the manufacture of polyurethane elastomers. Organic Synthesis. Manufacture of tetrahIdrofuran.

Application:

Polyethylene glycol and polyethylene glycol fatty acid esters are widely used in the cosmetics industry and the pharmaceutical industry. Because polyethylene glycol has many excellent properties: water solubility, non-volatility, physiological inertness, mildness, lubricity, and makes the skin moist, soft, and pleasant after use. Different molecular weight fractions of polyethylene glycol can be selected to change the viscosity, hygroscopicity and tissue structure of the product. Polyethylene glycol with low molecular weight (Mr<2000) is suitable for use as a wetting agent and consistency regulator, used in creams, lotions, toothpaste and shaving cream, etc., and also suitable for non-washed hair care products , Gives hair a silky luster. Polyethylene glycol with high molecular weight (Mr>2000) is suitable for lipsticks, deodorant sticks, soaps, shaving soaps, foundations and cosmetics. In cleaning agents, polyethylene glycol is also used as a suspending agent and thickening agent.
