Title: Improvements in or relating to bleaching and disinfectant washing and cleansing agents
IPC: C11D3/39
Filed: 1934-05-11
Abstract: Bleaching, washing, disinfecting, &c. compositions containing per-compounds, salts of pyro- or meta-phosphoric acid, and alkali, are stabilized by an addition of colourless sparinglysoluble tin compounds, such as stannic acid, magnesium, barium and other alkaline earth stannates and tin silicate, or soluble salts from which such insoluble compounds may be formed.  The insoluble tin compounds may be used in relatively small proportions, such as 0,5--3 per cent. The per-compounds include hydrogen peroxide and its organic compounds such as the addition compound of urea and hydrogen peroxide.  The alkaline component may be water glass, alkali metasilicate, soda, borax and alkali orthophosphates.  To the mixture may be added soap, saponins, alkali salts of sulphonated oils or sulphonated fatty alcohols, and other washing, cleansing, &c. agents.  The compositions may be put up in solid, liquid or paste form.  In examples of washing and bleaching compositions, the per-compound is sodium perborate, the alkaline compound is soda, the phosphoric acid salts are sodium pyrophosphates, polyphosphates and metaphosphate, the tin compounds are stannic acid and tin silicate, and other additions are soap and the sodium salts of sulphonated higher fatty alcohols or of oleylmethyl-taurin.  The tin compound may be added at any stage of the manufacture of the composition or before or during its use.ALSO:Washing &c. compositions containing percompounds, salts of pyro- or meta-phosphoric, acid and alkali, are stabilized by an addition of colourless sparingly-soluble tin compounds such as stannic acid, magnesium, barium and other alkaline earth stannates and tin silicate, or by soluble salts from which such insoluble compounds may be formed.
