Abstract: The sulphate of the coconut-oil fatty-acids monoester of diethanolamine is prepared by treating diethanolamine monosulphate in aqueous caustic soda solution with coconut oil fatty acid chlorides, Linoleyl b -phosphate g -glycerolamine is prepared by condensing g -glycerolamine with oleic acid at 160--175 DEG  C. and treating the product with phosphorus pentoxide at room temperature.  The sulphate of the condensate of lauryl amide and diethylene glycol is prepared by reacting a mixture of lauryl amide, diethylene glycol and fuming sulphuric acid at about 100 DEG  C.  A condensation product of palmityl amide and isethionic acid is prepared by dissolving palmityl amide in ether, adding isethionic acid while stirring, and stirring for about five hours at about 30 DEG  C.ALSO:A brushless shaving cream consists of a plastic emulsion of 5 to 30 per cent of oleaginous material, 50 to 80 per cent of water, 2 to 13 per cent of soap, and 0,5 to 5 per cent of a chemical compound (other than soaps which are metal salts of higher fatty acids) having oleophilic and hydrophilic groups in the molecule, the oleophillic group comprising a chain of not less than eight carbon atoms.  The oleaginous material consists essentially of a normally solid higher fatty acid, e.g. stearic or palmitic acid with or without a solid fat such as hydrogenated fats, lard, or waxes.  The soap may be formed in situ by the use of triethanolamine or caustic alkali.  There may also be added glycerol, glycol, perfumes, and antiseptics.

The formula also includes amides N-substituted by at least one alkylol group the terminal hydroxy-group of which is esterified with an inorganic oxygen-containing acid, for instance the alkali salt of an amide N- substituted by a sulphated or phosphated ethanol group, e.g. the substance C17H33.CO.NH.CH2.O.SO3.Na, the sulphate of the coconut oil fatty-acid ester of diethanolamine, the linoleyl b -phosphate of g -glycerolamine, the sulphate of the ester-like product from coconut-oil fatty-acid amides and diethyleneglycol.
