Thermal properties of a series of monodispersed alkyl poly (oxyethylene) ethers were measured using differential scanning calorimeter (DSC) in order to obtain basic informations on the thermotropic behavior of surfactants and oily soils in detergent systems. Melting points and heats of fusion of alkyl poly (oxyethylene) ethers were determined from melting peaks in DSC curves. Melting points increased with the carbon chain length. On the other hand, at a definite carbon chain length the lowest melting point was observed for 3 moles of oxyethylene. The heat of fusion increased in proportion to both alkyl chain and oxyethylene chain lengthes. The equation was proposed to express the heat of fusion as a function of alkyl chain and oxyethylene chain lengthes.
