Where does PEG-8 come from?

PEG-8, or polyethylene glycol 8, is a synthetic compound derived from the polymerization of ethylene oxide. It is commonly produced through the reaction of ethylene oxide with water or ethylene glycol, resulting in a hydrophilic polymer with various molecular weights. PEG-8 is widely used in cosmetics, pharmaceuticals, and food products due to its properties as a humectant and emulsifier. Its production is primarily industrial, and it is classified as a non-toxic and safe ingredient in many applications.
