Abstract: A washing and/or bleaching composition used for washing and/or bleaching textiles comprises an inorganic peroxy compound, e.g. a perborate, percarbonate, perphosphate, persilicate or persulphate, hydrogen peroxide or sodium peroxide and, as activator therefor, at least one compound containing one or more nitrogen atoms and having at least two acyl groups attached to the same nitrogen atom.  The activator may be an N-diacylated amine, e.g. diacetylmethylamine, diacetylethylamine, diacetylpropylamine, diacetylbutylamine, diacetylbenzylamine and diacetylaniline, N-diacylated ammonia, e.g. diacetamide and dipropionamide, N-diacylated amide, e.g. N-formyldiacetamide, N-acetyldiacetamide, N-propionyldiacetamide, N-butyryldiacetamide, N-valeryldiacetamide, N-caproyldiacetamide, N-acetylphthalimide, N-acetylsuccinimide and N,N-diacetylcyanamide, N-diacylated urethane, e.g. N,N-diacetylethyl-urethane and N-acetyl-N-propionylethylurethane, N-diacylated hydrazine, e.g. triacetylhydrazine, tetraacetylhydrazine, tripropionylhydrazine, N,N-diacetyl-N1-benzzoylhydrazine and N,N-diacetyl-N1-isopropylidenehydrazine, N-diacylated alkylene diamines, e.g. N,N,N1-triacetylmethylene diamine, N,N,N1, N1-tetra-acetylmethylene diamine, N,N,N1,N1-tetra-acetylethylenediamine, tetra-acetylhexamethylene diamine and tetra-acetylphenylene diamine, and the N-diacyl derivatives of semicarbazide, thiosemicarbazide and dicyanodiamide. The activator, which may be coated with a solid material soluble in the washing and/or bleaching liquid, may be present in the composition in an amount corresponding to 0,5-4 bound acyl groups per atom of active oxygen.  Detergent bleaching compositions may contain the sodium salt of dodecylbenzene sulphonic acid, lauryl isopropanolamide, tetrasodium pyrophosphate, pentasodium tripolyphosphate, alkaline waterglass (Na2O/SiO2 = 1/2 ), sodium carboxymethylcellulose, sodium sulphate, sodium soap, sodium carbonate, neutral waterglass (Na2O/SiO2 = 1/3 ,3), isononylphenolpolyglycolether, sodium tripolyphosphate, fluorescent brightening agents, dyestuffs and perfumes.  Specifications 907,357 and 907,358 are referred to.ALSO:A washing and/or bleaching composition used for washing and/or bleaching textiles, e.g. cotton, wool, linen, silk, viscose rayon, acetate rayon and polyamide, polyester, polyacrylonitrile and polyvinyl fibres, comprises an inorganic peroxy compound, e.g. a perborate, percarbonate, perphosphate, persilicate or persulphate, hydrogen peroxide or sodium peroxide and, as activator therefor, at least one compound containing one or more nitrogen atoms and having at least two acyl groups attached to the same nitrogen atom.
