What is ethylene glycol ？
- With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is 2-ethanediyl which has developed particularly rapidly in recent years. Do you know about 2-ethanediyl?
- The official answer：The properties vary according to the relative molecular mass, from colorless and odorless viscous liquid to waxy solid. Those with molecular weights of 200 to 600 are liquid at room temperature, while those with molecular weights above 600 gradually become semi-solid. From colorless and odorless sticky liquid to waxy solid. As the molecular weight increases, its moisture absorption capacity decreases accordingly. The product is soluble in water, ethanol, and many other organic solvents. Low vapor pressure, stable to heat, acid, and alkali. does not interact with many chemicals. It has good hygroscopicity, lubricity, and adhesion. Non-toxic, non-irritating. Average molecular weight 300, n=5～5.75, melting point -15～8℃, relative density 1.124～1.130. Average molecular weight 600, n=12～13, melting point 20～25℃, flash point 246℃, relative density 1.13(20℃). Average molecular weight 4000, n=70～85, melting point 53～56℃.
What’s the application of ethylene glycol ?
- Poly2-ethanediyls and poly2-ethanediyl fatty acid esters are widely used in the cosmetic and pharmaceutical industries. Poly2-ethanediyls have many excellent properties: water solubility, non-volatility, physiological inertness, mildness, lubricity, moistening of the skin, softness, and pleasant after-feel. Poly2-ethanediyls of different relative molecular mass grades can be selected to change the viscosity, hygroscopicity, and structure of the products. Poly2-ethanediyls with low relative molecular mass (Mr<2000) are suitable for use as wetting agents and consistency adjusters for creams, lotions, toothpaste and shaving creams, etc. They are also suitable for hair care products that are not washed to give hair a silky luster. Poly2-ethanediyl with high relative molecular mass (Mr>2000) is suitable for lip balm, deodorant stick, soap, shaving soap, foundation and beauty cosmetics, etc. In detergents, poly2-ethanediyls are also used as suspending agents and thickening agents. In the pharmaceutical industry, it is used as a base for ointments, emulsions, ointments, lotions, and suppositories. Commercially available poly2-ethanediyls (e.g. PolyethyleneGlycolNF, DowchemicalCo.) that are compliant with food and drug use are more suitable for cosmetic use. Methoxy poly2-ethanediyl and polypropylene glycol have applications similar to poly2-ethanediyl. Poly2-ethanediyls are widely used in a variety of pharmaceutical formulations, such as injectables, topical formulations, ophthalmic formulations, and oral and rectal formulations. Solid grade poly2-ethanediyls can be added to liquid poly2-ethanediyls to adjust viscosity for topical ointments; poly2-ethanediyl mixtures can be used as suppository bases; aqueous solutions of poly2-ethanediyls can be used as suspension aids or to adjust the viscosity of other suspension media, and poly2-ethanediyls are used in combination with other emulsifiers to increase emulsion stability. In addition, poly2-ethanediyl is also used as a film coating agent, tablet lubricant, controlled release material, etc.
