摘要

Scouring and detergent compositions, e.g. dish washing compositions, comprise a chlorine-releasing agent and a compound having the formula in which X is a hydrogen atom or alkyl group of 1-4 carbon atoms and Y is a hydrogen atom, a hydroxyl group or an alkyl group of 1-4 carbon atoms, or a water-soluble salt thereof, which acts as a sequestering agent in aqueous solutions. The chlorine-releasing agent may be ethyl, propyl, n-butyl or tert-butyl hypochlorite, N-chlorinated hydantoin, N-chlorosuccinimide, trichloroisocyanuric acid, dichloroisocyanuric acid, sodium dichloroisocyanurate, potassium dichloroisocyanurate, N-chlorinated melamine, ammeline or ammelide, sodium benzene-sulphochloroamide, sodium p-toluene - sulphonchloroamide, sodium hypochlorite, sodium chlorite, lithium hypochlorite, calcium hypochlorite or barium hypochlorite. The sequestering agent may be methylenediphosphonic acid, ethylidenediphosphonic acid, isopropylidenediphosphonic acid, 1-hydroxy-ethyl - idenediphosphonic acid, butylidene diphosphonic acid or a water-soluble salt thereof. The compositions may also contain sodium carbonate, sodium borate, sodium silicate, sodium sulphate, sodium tripolyphosphate, tetrasodium pyrophosphate, tetrapotassium pyrophosphate, wetting agents, synthetic detergents, e.g. sodium dodecyl benzene sulphonate, soaps, fillers and abrasives, e.g. silica and feldspar.ALSO:Sterilizing and disinfecting compositions comprise a chlorine-releasing agent and a compound having the formula in which X is a hydrogen atom or alkyl group of 1-4 carbon atoms and Y is a hydrogen atom, a hydroxyl group or an alkyl group of 1-4 carbon at atoms, or a water soluble salt thereof, which acts as a sequestering agent in aqueous solutions. The chlorine-releasing agent may be ethyl, propyl, n-butyl or tert-butyl hypochlorite, N-chlorinated hydantoin, N-chlorosuccinimide, trichloroisocyanuric acid, dichloroisocyanuric acid, sodium dichloroisocyanurate, potassium dichloroisocyanurate, N-chlorinated melamine, ammeline or ammelide, sodium benzene-sulphochloroamide, sodium p-toluene-sulphorchlonoamide, sodium hypochlorite, sodium chlorite, lithium hypochlorite, calcium hypochlorite or barium hypochlorite. The sequestering agent may be methylenediphosphonic acid, ethylidene-diphosphonic acid, isopropylidenediphosphonic acid, 1-hydroxyethylidenediphosphonic acid, butylidene diphosphonic acid or a watersoluble salt thereof. The compositions may also contain sodium carbonate, sodium borate, sodium silicate, sodium sulphate, sodium tripolyphosphate, tetrasodium pyrophosphate, tetrapotassium pyrophosphate, wetting agents, synthetic detergents, e.g. sodium dodecyl benzene sulphonate, soaps, fillers and abrasives e.g. silica and feldspar.ALSO:Bleaching compositions comprise a chlorine-releasing agent and a compound having the formula in which X is a hydrogen atom or alkyl group of 1-4 carbon atoms and Y is a hydrogen atom, a hydroxyl group or an alkyl group of 1-4 carbon atoms, or a water soluble salt thereof, which acts as a sequestering agent in aqueous solutions. The chlorine-releasing agent may be ethyl, propyl, n-butyl or tert-butyl hypochlorite, N-chlorinated hydantoin, N-chlorosuccinimide, trichloroisocyanuric acid, dichloroisocyanuric acid, sodium dichloroisocyanurate potassium dichloroisocyanurate, N-chlorinated melamine, ammeline or ammelide, sodium benzene-sulphocoloroamide, sodium p-toluene-sulphonchloroamide, sodium hypochlorite, sodium chlorite, lithium hypochlorite, calcium hypochlirite or barium hypochlorite. The sequestering agent may be methylenediphosphonic acid, ethylidenediphosphonic acid, isopropylidene-diphosphonic acid, 1-hydroxyethylidenediphosphonic acid, butylidene diphosphonic acid or a water soluble salt thereof. The compositions may also contain sodium carbonate, sodium borate, sodium silicate, sodium sulphate, sodium tripolyphosphate, tetrasodium pyrophosphate, tetrapotassium pyrophosphate, wetting agents, synthetic detergents, e.g. sodium dodecyl benzene sulphonate, soaps, fillers and abrasives e.g. silica and feldspar. The compositions may be in the form of a liquid bleach or dry bleach which is subsequently mixed with water.
