<p>1321267 Cleaning composition HENKEL & CIE GmbH 9 Oct 1970 [13 Oct 1969 20 Dec 1969] 48045/70 Heading C5D A powder or granular washing composition comprising an anionic surface-active agent, a perborate having less than 4 molecules of water of crystallization and a complex-forming builder in which (a) the weight of anionic surface-active agent together with any amphoteric and/or non- ionic surface-active agent present constitutes 5 to 40 weight per cent of the composition, (b) the perborate constitutes 7À5 to 50 weight per cent of the composition, (c) the complexforming builder together with any alkaline non- complex-forming builder present constitutes 15-80 weight per cent of the composition and (d) any nonionic surface-active agent present does not constitute more than 50 weight per cent of the surface-active agent present is prepared by a process in which (i) an aqueous suspension of surface-active agent and optionally complexforming builder is prepared in which not more than 20% of the total solids consist of hydrolysable complex-forming builder, (ii) this suspension is heated to produce a dry powder or granulate and (iii) the perborate in powder or granule form is added. The following ingredients are specified: anionic surface-active agents: sodium alkylbenzene sulphonate, sodium alkane sulphonate, sulphonated methyl stearate, sulphonated methyl palmitate, linear terminal olefin sulphonate, linear non-terminal olefin sulphonate, coconut fatty alcohol sulphate, tallow fatty alcohol sulphate, soap and sulphated oxyethylated tallow, coconut and oleyl alcohols, amphoteric surface-active agents: coconut fatty alkyl dimethyl ammonio methane carboxylate, coconut fatty alkyl dimethyl ammonio propane sulphonate, nonionic surfaceactive agents: oxyethylenated oleyl alcohol, builders: nitrilotriacetic acid, ethylene diamine tetra-acetic acid, sodium salts of 1-hydroxyothane - 1,1 - diphosphonic acid, 1 - aminoothane - 1,1 - diphosphonic acid, aminotri- (methylene phosphonic acid), methylamine di- (methylene phosphonic acid), ethylamine di- (methylene phosphonic acid) and ethylene diamine tetra-(methylene phosphonic acid), sodium tripolyphosphate, sodium carbonate, foam suppressants: di-(fatty alkyl amino) monochlorotriazine, N,N<SP>1</SP> ,N<SP>11</SP> - trialkyl melamine, paraffin oil, paraffin, textile softeners: a condensate of hardened beef tallow and N-hydroxyethyl ethylene diamine, sodium dioctyl acetate, sodium salt of 2-(di-coconut fatty alkyl amino)- propionic acid, optical brighteners of formula: wherein R 1 is phenylamino and R 2 is phenylamino or morpholino or of formula: where R, is sulphonamido and R 8 is chloro or 2,5 - di - (bonzoxazoyl - 2<SP>1</SP>) thiophene, others: carboxymethyl cellulose, water glass, magnesium silicate, sodium sulphate, protease, amylase and lipase enzymes.</p> |
