  • Preferred dyes their selection the expert has no difficulty, have a high storage stability and Insensitivity to the other ingredients of the agent and to light as well no pronounced substantivity towards textile fibers in order not to dye them.
  • the viscosity of the non-aqueous liquid compositions according to the invention can be adapted to the special requirements of different fields of application. In this way it is possible to formulate viscous and easily movable agents, but also viscous to pasty agents for washing or cleaning, which are known in the market as gels, can be produced. Agents which do not flow under the influence of gravity, that is to say are no longer pourable and have a consistency which can be spread or cut, can also be produced without problems in the context of the present invention.
  • T 70 ° C., shear rate: 100 s -1
  • a significantly higher viscosity may be indicated - this can lead to dimensionally stable masses in which a viscosity in the above sense can no longer be meaningfully stated .
  • the agents according to the invention are produced in a manner known per se Mixing the ingredients in stirred tanks. Unless it's for a specific end product is desired, the solids contained in the agents according to the invention can by be further crushed a wet grinding step to ensure the separation stability of the agents to increase further.
  • Such operations familiar to the person skilled in the art are suitable, for example Colloid mills, roller mills or annular gap or agitator ball mills.
  • the cationic stabilizing agents to be used according to the invention can be added take place at any point in such a conventional manufacturing process. For example it is possible to coat the bleach with the cationic stabilizers and these coat bleach particles in a stirred tank to the other ingredients to give, whereby here, of course, a grinding step can follow. Also one Add the cationic stabilizing agent as a solid or pasty pure substance or as Solution is easily possible both before and after a grinding step. Usually bleach and bleach activators are not used together before Grinding incorporated into the media because the intimate contact of the substances during the grinding process decomposes them can promote. If the bleach activators are added after a grinding step, the cationic stabilizers can be added in this stirring and homogenization step be, it is of course also possible to use the bleach activators to coat the cationic stabilizers.
  • the use of the compounds mentioned leads to liquid agents which have increased bleach stability and which also maintain this property over long storage intervals.
  • the isothermal microcalometry has proven to be particularly suitable.
  • the heat of the usually exothermic decomposition reaction is also detected very sensitively in small sample quantities.
  • the stability compared to the decomposition of a given system the smaller the smaller in one amount of heat produced is in joules for a certain period of time.
  • TAM 2277 microcalorimeter was used for the present investigations (Thermometric AB, Sweden). This continuously records the pro Unit of heat generated in a sample in watts.
  • the investigated liquid detergent E according to the invention contained a cationic stabilizing agent, while the comparative example V was free of the stabilizing agents used according to the invention. Small amounts of water and Fe (III) ions were added to both formulations in order to simulate realistic conditions (contamination from production plants, etc.).
  • the composition of the liquid detergents is shown in Table 1.
