Definitions

  • This invention relates to processes of bleaching and to bleaching compositions; in particular it relates to processes and to compositions suitable for removing stains from textile materials.
  • compositions contain an inorganic persalt such as sodium perborate or percarbonate to provide bleaching properties.
  • per-salts provide a satisfactory bleach when the detergent is used at the boil, but at lower temperatures their action is rather slow. This disadvantage is becoming important with the growing use of washing machines Which operate at a temperatom of, for example, 50-60 C. It is an object of the present invention to provide a more effective bleach in the normal washing period at this temperature than is obtained with the per-salt alone.
  • Processes and compositions according to the invention also find application in the textile industry and in commercial laundering.
  • Esters which may be used in bleaching compositions and processes of the invention are those which give a titre of 1.0 millilitres or more in this test after one minute or after five minutes, or both.
  • a bleaching process in which is used an aqueous solution of hydrogen peroxide and an ester of carbonic acid or pyrocarbonic acid which gives a titre of not less than 1.0 millilitres of 0.1 N sodium thiosulphate in the test defined above.
  • the present invention further provides a bleaching composition which contains an inorganic per-salt together with an ester of carbonic acid or pyrocarbonic acid which gives a titre of not less than 1.0 ml. of 0.1 N sodium thiosulphate in the test defined above.
  • Esters which give a titre of not less than 1.0 ml. of 0.1 N sodium th'iosulphate in the test defined above and hence may be used according to the invention include compounds Within the class R O.CO.OR in which R exerts an electron attracting effect and R is an alkyl, aryl, or alicyclic radical or a substituted alkyl, aryl or alicyclic radical.
  • esters should not yield easily oxidisable hydrolysis products such as polyhydric phenols.
  • esters within the scope of the invention that is those which give a titre of at least 1.0 ml. of 0.1 N sodium thiosulphate in the test defined above, are:
  • inorganic per-salt is meant a salt which will give rise to hydrogen peroxide in aqueous solution.
  • Suitable compounds are alkali metal perborates, percarbonates, perpyrophosphates and persilicates. These are believed not to be true per-salts in the strict chemical sense but to contain hydrogen peroxide of crystallisation, which is liberated in aqueous solution.
  • the invention can be applied to bleaching baths such as are used for treating textiles, to wash liquors, such are used in commercial laundering and to solid bleaching compositions.
  • Solid bleaching compositions may contain, in addition to a per-salt and an ester according to the invention, inert salts, alkaline agents and a small proportion of detergent.
  • the invention may further be applied to detergent compositions, which contain an organic detergent, which may be soap or an organic soapless detergent. Suitable organic soap'less detergents are the alkylaryl sulphonates, alkyl sulphates and the salts of esters or ethers of isethionic acid.
  • compositions according to the invention should preferably contain one or more alkaline substances in amounts such that similar compositions not containing esters would give a pH value within the range 9-11 when dissolved at the desired bleaching concentration.
  • Most common detergent compositions contain alkaline material sufiicient for this purpose. Suitable alkaline materials are, for instance, soap, alkali-metal carbonates, phosphates (including orthophosphates and water-soluble condensed phosphates, such as tripolyphospirates and pyrophosphates) and silicates.
  • alkali sufficient to give an initial pH of 9-11 is preferably present in the bleaching or Wash liquor before addition of the ester.
  • compositions according to the invention may contain any of the conventional adjuncts present in detergent compositions. There may be mentioned, supplementary builders, inert and organic materials such as alkali metal sulphates, chlorides, carboxyrnethylcellulose and fluorescent agents.
  • compositions according to the invention must not contain water in an amount sufiicient to permit appreciable chemical reaction between the components prior to use.
  • per-salt and ester which may be present in compositions according to the invention will depend on the time and temperature of bleaching, the degree of bleaching required, the concentration of the bleaching solution and the individual ester and per-salt used. Under most conditions, these proportions should be such as to give a per-salt concentration in solution equivalent to 0.001 to 0.1% available oxygen.
  • compositions according to the invention containing widely varying ratios of per-salt to ester. It is convenient to measure the activity of the per-salt in terms of available oxygen. Generally ratios of from A to 2 and particularly from /2 to 1 /2. molecules of ester per 1 atom of available oxygen are preferred. (In converting such ratios to ratios by weight, account must be taken of the molecular weight of the ester and the avialable oxygen content of the per-salt used.) In particular, it is preferred to use approximately chemically equivalent amounts of ester and per-salt.
  • the preferred weight ratio is from 2 to 15 parts of ester to 1 part of hydrogen peroxide (100%) depending on the molecular Weight of the ester used.
  • compositions according to the invention are to be used primarily as a bleach, for instance, for addition to alkaline textile bleaching baths or wash liquors, such compositions may contain any proportion of ester and per-salt, these components being preferably present in the ratio of M1. to 2 molecules of ester per 1 atom of available oxygen, preferably /2 to 1 /2 molecules per 1 atom of available oxygen.
  • compositions of the invention When an organic detergent is present in compositions of the invention, improvements in bleaching can be obtained at normal washing concentrations. Thus, for example, using a detergent composition of the invention at a concentration of 1% in aqueous solution improvements may be obtained if amounts of as little as 1% of persalt and 2% of ester by weight of the composition are present. In such compositions, the amount of per-salt taken should provide at least 0.1% available oxygen based on the composition.
  • detergent compositions will contain from about to about 50% by Weight of organic detergent.
  • the mixed ester/per-salt content may be as high as 70% by weight provided that these components are taken in ratios of A to 2, preferably /2 to 1 /2 molecules of ester per 1 atom of available oxygen.
  • Etfective proportions of ester and per-salt in detergent compositions will lie in general within the range of 2% to 30% of ester and 1% to 75% of per-salt by weight of the composition.
  • Example Bleaching solutions were prepared containing:
  • a length of cotton cloth was stained by immersion in boiling tea extract for one hour. It was then thoroughly rinsed, dried and cut into pieces whose percent refiectances were measured in a Hunter reflectometer using the blue filter. The percent reflectance of the test pieces was measured again after bleaching. The bleach obtained 'was expressed as the difference in the two percent readings on each test-piece.
