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.
