A general chromatographic method has been developed for separating nonionic surface-active agents from each other and fromrelated nonionic materials, using silica gel as adsorbent. The mixture, adsorbed on a silica gel column, is separated by eluting suc-cessively with chloroform, 1: 99 (v./v.) ethyl ether-chloroform, 1: 1 (v./v.) ethyl ether-chloroform, 1: 1(v./v.) acetone-chloroform, 1: 19(v./v.) methanol-chloroform, 1: 9(v./v.) methanol-chloroform, and 1¡ 2 (v./v.) methanol-chloroform. Results obtained with a number of three-and four-component mixtures are de-scribed.COMPOSITIONS CONTAINING nonionic surface-active agents commonly contain more than one nonionic substance. These compositions often con-tain both water-soluble and oil-soluble surfactants to obtain a better balance of properties, and in addition, usually contain other nonionic, nonsurface-active materials, such as hydrocarbon
