Polyethylene glycol series products are non-toxic, non-irritating, slightly bitter, water soluble, and good solubility in a variety of organic ingredients. They have excellent lubricity, moisture retention, dispersity, adhesive, antistatic agent and softness, widely used in cosmetics, pharmaceutical, chemical fiber, rubber, plastic, paper making, paint, electroplating, pesticides, metal processing and food processing.
Polyethylene glycol and polyethylene glycol fatty acid esters are widely used in the cosmetic and pharmaceutical industries. Because polyethylene glycol has water-soluble, non-volatile, physiological inertia, mild, lubricity, wettability, softness, feel happy after use and other excellent properties. Polyethylene glycol can be selected from different molecular weight levels to change the viscosity, hygroscopicity and structure of the product. As the molecular weight increases, the hygroscopicity of PEG decreases. 8000 PEG has almost no hygroscopicity, but can inhibit corrosion and absorb moisture from high humidity air.
Polyethylene glycol is used in the cosmetic industry to regulate viscosity, melting point or as a base for lubricants and softeners. At present, the cosmetics market in the downstream industry of polyethylene glycol in China is developing at a rapid rate of 20% per year. Therefore, it is expected that the cosmetic polyethylene glycol industry in China will also develop rapidly in the future. It is expected that the overall supply of polyethylene glycol for cosmetics in China will balance and slightly exceed the market demand in the future.
Polyethylene glycol (Mr2000) is used as a wetting agent and consistency regulator in comparison to its molecular weight, in creams, lotions, toothpastes and shaving creams, and in uncleaned hair care products to give hair a silken shine. Polyethylene glycol (Mr>2000) is suitable for lipstick, deodorant stick, soap, shaving soap, foundation, beauty cosmetics, etc. Polyethylene glycol is also used as a suspending agent and thickener in cleaning agents. In the pharmaceutical industry, it is used as a base for ointments, emulsions, ointments, detergents, and suppositories. Solid grade polyethylene glycol can add liquid polyethylene glycol to adjust the viscosity, used for local ointment; Polyethylene glycol mixture can be used as suppository base; Polyethylene glycol aqueous solution can be used as suspension agent or other suspension medium viscosity; Polyethylene glycol and other emulsifiers can increase the stability of emulsions. In addition, polyethylene glycol is also used as film coating agent, tablet lubricant, controlled release material, etc.
From the above understanding, the production and sales of cosmetic polyethylene glycol industry in China still have a great space for development in the future.
