About PEG-400

PEG-400 is a polymer of ethylene oxide.[1] The number 400 in the name indicates the average number of added ethylene oxide units; with the same base structure, changing this number can affect water miscibility and the formulation’s viscosity and spreadability. In cosmetics, it is used to help formulation ingredients bind together and maintain their form, keep emulsions of water and oil from separating easily, and dissolve other raw materials to create a uniform formulation.[2]
