Liquid or pasty detergent compositions comprise (a) fatty alcohol sulphates, and (b) mono- and/or di-salts of sulpho-fatty acids containing not more than 50% of fatty acid residues having 16 or more carbon atoms, the amount of (b) being not greater than that of (a); and optionally (c) salts of esters of C8-24 sulpho-fatty acids, in which case the proportion of (a) to the total of (b)+(c) lies in the range 10: 1 to 1: 10. The alcohol residues in (c) may be derived from mono- or poly-hydric alcohols or ether-alcohols, and the cations of (a), (b) and (c) may be one or more of Na, K, Li, NH4 and mono-, di- and tri-ethanolamine. Further optional ingredients include C1-5 monohydric alcohols, C2-5 glycols, di- and tri-ethylene glycol, glycerine, polyglycerines, partial ethers of any of the foregoing polyhydric alcohols with C1-4 monohydric alcohols, Na2SO4, NaCl, NaNO3, alkali metal carbonates, orthophosphates, pyrophosphates, polyphosphates, polymetaphosphates, and silicates, polyacrylates, polymethacrylates, carboxymethylcellulose, cellulose sulphates, and fatty acid amides and alkylolamides. |
