Definitions

  • the present invention relates to the bleaching of household linen in a washing cycle comprising two stages.
  • formulations for washing household linen are essentially marketed, qualified as complete, containing both the agents ensuring detergency and those ensuring bleaching.
  • surfactants sodium polyphosphates such as, in particular, sodium tripolyphosphate.
  • persalts in particular sodium perborate.
  • the activators can be of various chemical nature.
  • the most used industrially and the most commonly cited are however compounds such as for example tetraacetylethylenediamine (TAED), ol-acetoxy-ol-methyl-N, N'-diacetylmalonamide which is the subject of French patents published under the numbers 2,363,541 and 2,363,629, cyanamide and its derivatives which are the subject of the French patent published under the number 2,340,371.
  • TAED tetraacetylethylenediamine
  • ol-acetoxy-ol-methyl-N N'-diacetylmalonamide
  • cyanamide and its derivatives which are the subject of the French patent published under the number 2,340,371.
  • the process of the invention makes it possible to improve the bleaching effect of peroxidized bleaching agents such as persalts but also hydrogen peroxide when they are used at a temperature at most equal to 70 ° C. in the presence of an activator during a household linen washing cycle.
  • the bath of the first stage contains, in kind and in quantity, the detergent products usually present in a conventional prewash currently carried out using a so-called complete detergent composition starting a known cycle, such as for example sodium tripolyphosphate.
  • detergent compositions can also contain, in nature and in quantity, ingredients usually present in such detergent compositions such as for example complexing agents of metal ions, surfactants, brighteners.
  • the bleaching agents present in the bath of the second step are chosen from those commonly used in complete detergent compositions to ensure in them the function of bleaching bleachable stains in household linen, such as for example hydrogen peroxide, persalts or peroxyhydrates such as sodium perborate, sodium percarbonate and urea peroxyhydrate.
  • the concentration of active oxygen resulting from the presence of such peroxidized bleaching agents is generally between 0.004 and 0.03% by weight relative to the weight of the bath.
  • the activator accompanying the bleaching agent in the bath of the second step can be of various nature without being called into question the observation of the improvement caused by the implementation of the invention. High whitening effects are however particularly observed when the activator is of the TAED type or cyanamide such as calcium cyanamide.
  • the molar ratio of peroxidized bleaching agent / activator can vary within fairly wide limits depending in particular on the nature of one or the other compound. Often it is between 1 and 10. When, for example, hydrogen peroxide or sodium perborate are chosen as bleaching agents, the activator being of the cyanamide or TAED type, it may more generally be between 5 and 10.
  • At least one proteolytic enzyme can be used during the first step.
  • detergent compositions comprise compounds of sufficiently alkalizing character so that the pH in the first stage is reached by their mere presence in this stage. Otherwise, an additional alkaline agent such as sodium hydroxide, among others, can be added to them.
  • the pH in the second stage is reached by means of an alca agent usual flax which cannot be oxidized or which cannot be reduced by peroxidized bleaching agents, sodium hydroxide being most frequently chosen for essentially economic and convenience reasons.
  • the preferred pH range in the second step is 9.5 to 12.5.
  • the temperature range, 40 ° C-60 ° C is indicated for carrying out the invention because it only leads, at a temperature below 40 ° C, to an insignificant improvement in the effect of bleaching and results, at a temperature above 60 ° C, in a rapidly prohibitive energy expenditure in comparison with the additional improvement then observed.
  • the cumulative duration of the first and second stages is generally less than 1 hour, each stage not exceeding 0.5 hours most often.
  • the measurements are carried out using an ELREPHO spectrophotometer, filter No. 8, from the company CARL ZEISS.
  • Examples 1 to 8 They relate to the tests carried out when the calcium cyanamide is the activator involved.
  • Examples 1 to 5 are carried out according to the invention, examples 6 to 8 given by way of comparison according to the conditions defined above for the "complete" washing, it being specified that the first step in example 5 and the step unique in Example 8 are performed in the presence of ESPERASE.
  • Table I collates the results obtained as a function of the temperature and of the pH of the bath of the second step of the process of the invention or of the "complete" washing bath.
  • Examples 9 to 13 They relate to the tests carried out when the TAED is the activator used.
  • Table II below collates the results as a function of the temperature and of the pH of the bath of the second step of the process of the invention or of the "complete" washing bath.
