An opaque aqueous detergent composition comprises (a) a solution of a water soluble anionic organic detergent salt, of which at least part, usually 2-10%, is an alkylglyceryl ether sulphonate containing 12-14 carbon atoms in the alkyl group, in which is suspended as a crystalline opacifying agent (b) an alkylglyceryl ether sulphonate containing 16-18 carbon atoms in the alkyl group, the composition also containing as a graining agent for (b), (c) sodium nitrate generally in an amount of 2-20%, but preferably 6-18%. In total, (a) generally comprises 15-40%, more preferably 20-35%, and may include sodium coconut fatty acid monoglyceride sulphate or sulphonate, fatty acid isethionate or fatty acyl-N-methyl tauride, but preferably contains sodium alkyl sulphate, alkylbenzene sulphonate, or alkyl polyoxyethylene ether sulphate containing 3 units of ethylene oxide per molecule. The alkyglyceryl ether sulphonate necessarily present in (a) is suitably obtained from coconut alcohols, while that of (b) is derived from tallow alcohols; (b) is present in an amount of 1-9%, preferably 2-5%. A water soluble organic solvent such as ethanol, propanol, or isopropanol, or less desirably ethylene or propylene glycol, is generally present in amounts up to 15%, usually 5-10%, together with up to 5% sodium benzene, toluene, or xylene sulphonate. Fatty acid alkanolamides, dyes, perfume, and optical brighteners may also be incorporated, and the compositions used for laundry purposes, dishwashing, or as shampoos. (All percentages are by weight of the total composition.) |
