Abstract: Dish-washing composition containing alkali polyphosphates and silicates, surfactants, peroxized oxygerating agents, enzymes and sufficient alkali for providing a washing bath of pH 11.5.

Abstract: This washing machine is provided with an electro chemical cell (4) having a brine tank (9) provided with a metering piston (16a, b 16b) actuated by an electro magnet (21) and connected by an electro valve (14) controlling a connection conduit (3) to a water supply conduit (1). The inlet opening of such connection conduit into the cell (4) is controlled by a float valve (11). The electro valve is a two-way valve (14, 14a) and controls simultaneously the outlet conduit (13) which opens into the washing tub of the washing machine. The power supply of the cell (4) is controlled by the program selector (8) of the machine.

Abstract: This invention relates to a method for washing and bleaching textiles.The method according to the invention, which is carried out by means of an aqueous wash bath containing a detergent substantially free from bleaching agent, is characterized in that said bleaching is performed by incorporating into said wash bath, at the required moment, an aqueous alkaline oxidizing solution containing in particular hydrogen peroxide ions, said aqueous alkaline oxidizing solution being produced electrolytically, immediately before its incorporation into said wash bath, by reducing oxygen at a cathode in an alkaline medium.

Abstract: A detergent composition mainly for automatic laundering machines which comprises, on the basis of 100 parts by weight of total composition, at least 60 parts of soap and no more than 10 parts of a mixture of surfactants comprising 10 to 30% of at least one non-ionic polyoxyalkylated surfactant and 90 to 70% of an anionic surfactant selected essentially from .alpha.-sulfonated fatty acids derivatives, the remainder of the composition comprising at least one ingredient selected from alkaline detergent additives, bleaching agents, optical brighteners, fragrances, antiredeposition agents and enzymes.The non-ionic surfactants are preferably fatty acid amides derived from tallow, copra or palm-oil condensed with polyoxyethylene residues.The anionic surfactants are preferably .alpha.-sulfonated fatty esters or amides derived from tallow, copra or palm-oil.
