[Also in Divisions C7 and D1] A cleaning composition stabilized against deterioration during storage comprises (a) a chlorinated cyanuric or isocyanuric acid or a salt, thereof or alkali metal or zinc hydrosulphite, (b) boric oxide and (c) an alkali metal or ammonium carbonate. The boric acid and carbonate may be present in proportions such that the pH of the mixture is 5-12, the mole ratio of boric oxide to carbonate, expressed as B 2 0 3 /Na 2 0, preferably being from 8 : 1 to 0-5 ; 1. Compositions containing chlorocyanuric or chloroisocyanuric acid or a salt thereof may also contain synthetic detergents, builder salts, e.g. sodium sulphate, chloride or silicate, borax or an alkali metal orthophosphate or polyphosphate, anti-caking agents, e.g. bentonite and magnesium silicate, and tableting ingredients, e.g. an alkyl aryl sulphonate. Hydrosulphite compositions may also contain citric, tartaric, lactic, malic, maleic, p-toluene sulphonic, glutamic, oxalic, gluconic or sulphamic acid or an alkali metal acid sulphate, acid phosphate, acid phthalate or acid citrate, and sodium metabisulphite, and may be used in the form of aerosol spray compositions containing mineral oil, isobutane and Freon (Registered Trade Mark), and finely divided calcium silicates. |
