Definitions

  • the present invention relates to a detergent compound based on polyphosphate, of a water-soluble alkali metal alkylsiliconate or of one of its water-soluble condensates and of an optically active water-soluble substance intended to be distributed uniformly over a room to be washed, as well as its preparation. It also relates to the detergent use of this compound.
  • Detergent compositions in the powder form in particular, contain, in addition to their usual constituents of the builders or surfactants type, numerous additives such as dyes, optical brighteners, photobleaching agents, softening agents, antiseptic agents, etc.
  • these additives which function by adsorption on the textile fibers, require a homogeneous distribution over the part to be washed. Indeed, if they are located in particular places on the article to be treated, there appears, at the end of the washing or after drying of it, colored spots or halos, which constitutes a disadvantage completely unacceptable and which also leads to a lowering of the expected performance of the product.
  • Document FR-A-2 354 381 describes a detergent composition containing an anti-foaming substance consisting of a tripolyphosphate support, a polyorganosiloxane anti-foaming agent enclosed in a mixture of a water-insoluble wax and d an emulsifier insoluble in water.
  • Document EP-A-210 114 describes an anti-foaming substance comprising a support consisting of sodium tripolyphosphate and an acid orthophosphate and / or sodium acid pyrophosphate, and an anti-foaming composition consisting of an oil polyorganosiloxane and silica.

  • the main object of the invention is a means or a system making possible the homogeneous distribution of an optically active detergent additive on the article to be washed, this whatever the type of washing used.
  • a second object is the preparation of such a system.
  • the detergent compound according to the invention comprises a support constituted by an at least partially hydrated polyphosphate and at least one water-soluble optically active substance, and is characterized in that said optically active substance intended to be uniformly distributed over a part to be washed, is located at least partially inside said support, and in that said compound also contains a water-soluble alkali metal alkylsiliconate or one of its water-soluble condensates placed or adsorbed on the surface of said support.
  • the process for the preparation of the washing compound consists in mixing with the anhydrous or partially hydrated polyphosphate an aqueous solution comprising the above-mentioned substance and product.
  • the invention relates to a detergent composition which is characterized in that it comprises a detergent compound of the above type or prepared by the process described above.
  • the detergent compound defined above ensures a delayed release of the additive, and thus makes it possible to reduce the risks of additive - laundry contact. It therefore provides a completely homogeneous distribution of this additive on the laundry and this even for hand washing in a bowl. In addition, this presentation of the additive makes it possible to impart a visual effect to the washing powder if necessary.
  • the detergent compound according to the invention therefore consists of three types of elements, namely an at least partially hydrated polyphosphate incorporating or supporting on the one hand, at least one water-soluble optically active substance intended to be uniformly distributed over a room to be washed (called in the rest of the description "the substance”), and on the other hand a product chosen from alkylsiliconates of water-soluble alkali metals or their water-soluble polycondensates, (called in the rest of the description "the product”).

  • the support must have a density of between 0.4 and 0.8 and preferably between 0.6 and 0.8.
  • polyphosphate and in particular TPP in the form of particles, very difficultly absorbs water, which consequently hinders the introduction via water, of the substance at the heart of the particles, and that in sufficient quantity.
  • the density of the support is less than 0.4, the compound is difficult to handle.
  • particles are generally used whose average size is between 200 ⁇ m and 800 ⁇ m, and preferably between 600 ⁇ m and 700 ⁇ m. This particle size is recommended to obtain the optical effect described above, when the aforementioned substance is colored.

  • the detergent compound comprises a product chosen from water-soluble alkali metal alkylsiliconates and their water-soluble polycondensates.
  • siliconates are well known products, they are salts of silicone acid or its derivatives.
  • R is an alkyl residue of 1 to 10 carbon atoms and more particularly of 1 to 6 atoms.
  • R can be a methyl, ethyl, propyl, butyl or isobutyl radical.
