Definitions

  • the invention relates to a bleach mixture which, if required, can be added to a detergent by the consumer or additionally added to a wash liquor in order to increase the bleaching effect during the washing treatment, in particular in the temperature range between 30 ° C and 60 ° C.
  • Bleaching agents consist of a combination of a perhydrate, in particular sodium perborate, with a bleach activator, a bleach activator being understood to mean hydrolyzable compounds which form peracids with the perhydrate in aqueous solution. Since mixtures of the two components already react with one another in the presence of small amounts of atmospheric moisture and thus suffer loss of activity, it is necessary to separate the powder particles of the individual components as spatially as possible, which is achieved by mixing with larger proportions of powdered blending or diluting agents and / or envelopes one of the two components can be done. If the components are added to a detergent, this can already act as a separating and blending agent. However, there is then no longer any possibility for the consumer to dose the bleaching component individually according to the respective requirements or, for example when washing highly sensitive textiles, to dispense entirely with a bleaching component.
  • the sodium perborate is preferably present as a monohydrate and is preferably present in amounts of 10 to 30% by weight and in particular 15 to 25% by weight. Its average grain size is generally 0.2 to 0.6 mm, the proportion of dusty to fine-grained perborate with a particle size of less than 0.1 mm should be less than 5% by weight, preferably less than 1% by weight . Furthermore, the content of the perborate used in particles with a grain size of more than 0.8 mm should not be more than 10% by weight and with more than 1.6 mm should not be more than 1% by weight. Suitable grain fractions consist of 85 to 100% particles 0.1 to 0.8 mm in size.
  • the TAED can also be in granulated form, provided that these granules consist of a correspondingly fine-grained TAED and a water-soluble granulating agent, as is the case, for. B. is described in EP-C 0 037 026.
  • the granulating agent consists of cellulose ethers in proportions of less than 10%, based on TAED granules.
  • the agents are prepared by simply mixing the constituents, it being advantageous that TAED and perborate monohydrate are not mixed directly with one another without the presence of the separating and blending agent.
  • the procedure is to mix the 3 components simultaneously in one operation or to either mix one of components (a) and (b) with component (c) and then add the missing component. Mixing can be carried out continuously or in batches with the aid of conventional mechanical mixing devices.
  • Particularly suitable sequestering agents are amino group-containing phosphonic acids in the form of the water-soluble salts, such as aminotri- (methylenephosphonic acid), ethylenediaminetetra- (methylenephosphonic acid), diethylenetriaminepenta- (methylenephosphonic acid) and their higher homologues. They are usually in the form of sodium salts.
  • Other suitable sequestering agents are homo- and copolymers of acrylic, methacrylic and maleic acid, for example an acrylic acid-maleic acid copolymer in a ratio of 5: 1 to 1: 1, which are also generally in the form of the Na salts.
  • the proportion of surfactants can be, for example, 0 to 12% by weight and the proportion of sequestering agents can be 1 to 3% by weight.
  • the average grain size of the optional components suitably corresponds to the average grain size of components (a) to (c).
  • These additives can increase the cleaning ability and in the case of the sequestering agents to a certain extent also the shelf life of the agents. They have no appreciable influence on the induction behavior.
  • Example 1 645 g / l
  • Example 2 640 g / l
  • Comparison A 600 g / l
  • Comparison B 590 g / l.
