China Drying Network News "Anqing Chemical Industry New Material Industry Concentration Zone Development Outline" passed the expert's demonstration. The "Outline" pointed out that Anqing should focus on the integration of resource elements, strengthen the construction of independent innovation system, cultivate the new chemical materials industry into the largest pillar industry in Anqing, and turn Anqing into the largest chemical new material production base in Anhui. The Anqing Chemical New Material Industrial Concentration Zone should focus on the development of new chemical materials with three major synthetic materials as the main body, and select the best for the development of fine chemicals and specialty chemicals. The enterprises entering the zone must start from the source to reduce the generation of pollutants and ensure that they meet the national emission standards. Anqing Chemical New Material Industrial Concentration Zone has been planned and constructed into a new type of industrial city, which is adjacent to the old city of Anqing, with complementary functions and differentiated development.
Polyethylene glycol and polyethylene glycol fatty acid esters are widely used in the cosmetic and pharmaceutical industries. Because polyethylene glycol has many excellent properties: water-soluble, non-volatile, physiologically inert, mild, lubricating and moisturizing the skin, soft, and pleasant after use. Different relative molecular weight fractions of polyethylene glycol can be selected to change the viscosity, hygroscopicity and organizational structure of the product. Low molecular weight polyethylene glycol (Mr<2000) is suitable for use as a wetting agent and consistency regulator for creams, lotions, toothpaste and shaving cream, etc. It is also suitable for unwashed hair care products. Gives hair a silky shine. Polyethylene glycol with high molecular weight (Mr>2000) is suitable for lipsticks, deodorant sticks, soaps, shaving soaps, foundations and beauty cosmetics. In cleaning agents, polyethylene glycols are also used as suspending and thickening agents. In the pharmaceutical industry, it is used as a base for ointments, creams, ointments, lotions and suppositories.
