polyethylene glycol and propylene glycol 

PEG 200 Full name is Polyethylene glycol, molecular weight 200 CAS NO.: 25322-68-3 It can be used as a medium for organic synthesis and a heat carrier with higher requirements.  In the daily chemical industry, it is used as a moisturizing agent, inorganic salt solubilizer, and viscosity modifier; In the textile industry, it is used as a softener and an antistatic agent;  In the paper and pesticide industries, it could used as a wetting agent. 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…
