Abstract: 1314665 Treating textiles with brighteners and bactericides HENKEL & CIE GmbH 19 April 1971 [28 March 1970] 25478/71 Heading ASE [Also in Divisions C3 C5 and Dl] Textiles, e.g. cotton and polyamide fabrics, are brightened with a composition comprising (a) 1 part by weight of the optical brightener: (b) 0.1 to 10 parts of the optical brightener: in which X stands for Na, K, NH 4  or H and Y stands for a morpholino, C 1 -C 3  alkylamino or C 1 -C 3  alkoxy C 1 -C 3  alkyl amino group, and (c) 1 to 100 parts by weight of the bactericides 1-hydroxy-pyridine-2-thione, 2-hydroxy-2',4',4- trichlorodiphenyl ether, 3-trifluoromethyl-4,4'- dichlorocarbanilide and 3,4,4'-trichlorocarbanilide. The composition may be in the form of a paste, powder, granules, lumps or aqueous preparation for washing, rinsing or bleaching which may contain (i) detergents, e.g. alkyl benzene, olefine or alkyl sulphonates, sulpho fatty acid esters, alkyl sulphates, sulphates of alkoxylated fatty alcohols; sulphated partial ethers or esters of polyhydric alcohols, sulphates of alkoxylated fatty acid amides and alkyl phenols, fatty acid taurides, fatty acid isethionates, soaps of coconut, palm kernal or tallow fatty acids, N-alkyl sulpho betaines, and polyglycol ethers of alcohols, fatty acids or alkyl phenols, (ii) cleaning salts, e.g. polyphosphates or silicates, (iii) organic complexing substances, e.g. salts of aminopolycarboxylic acids and aminopolyhposphonic acids, (iv) neutral salts, e.g. Na 2 SO 4  and NaCl, (v) substances for regulating pH, e.g. bicarbonates, carbonates, borates, hydroxides, lactic and citric acid, (vi) bleaching agents, e.g. H 2 O 2 , alkali metal perborates, percarbonates, perphosphates, persulphates and hypochlorites, urea perhydrate, chlorinated trisodium phosphate and chlorinated cyanuric acid or its alkali metal salts, with or without an activator therefor, e.g. tetraacetyl glycoluril and magnesium silicate, (vii) greying inhibitors, e.g. sodium cellulose glycollate and alkali metal salts of synthetic polymers with free COOH groups, (viii) foam inhibitors, (ix) enzymes and (x) nonquaternary high molecular weight ammonium compounds. Softening compositions may contain compounds of formulae wherein R 1  and R 2  are saturated or unsaturated haydrocarbon of 11-25C, R 3  is alkyl or hydroxy alkyl (1-3C), R 4  is as for R 3  or benzyl. R 5  is as for R 3  or H, R 6  is alkylene 1-3C and A is an anion, or the condensation product obtained by reaction of a hardened tallow fatty acid glyceride with amino ethanolamine and may be in the form aqueous dispersions or pastes, lard-like solids or powders containing neutral salts, stabilisers or organic solvents. Stiffening and dressing compositions may contain, starch, alkoxylated starch, CMC, methyl or ethyl cellulose, hydroxyethyl cellulose, polyethylene oxide, polyvinyl alcohol, polyvinyl acetate or a partially saponified form thereof, polyvinyl pyrrolidone, polyacrylonitrile and polyacrylic acid as well as neutral salts, solvents and softeners and ironing assistants e.g. paraffin and hard waxes and may be in the form of powders, pastes or aqueous dispersions.
