Polyethylene glycol (PEG) molecule. Molecular model of the compound poly(ethylene glycol) butyl hydroxymethyl (C33.H68.O15). This is a polymer chain of 14 units of ethylene glycol, terminated at one end by an CH3OH hydroxymethyl unit and at the other end by a CH3(CH2)3 butyl unit. Chemicals such as this are used in many cosmetic, medical and industrial products. Atoms are represented as spheres and are colour-coded: carbon (grey), hydrogen (white) and oxygen (red).
