Definitions

  • the present invention relates to new detergent compositions suitable for washing dishes in a washing machine, and to a process for their preparation.
  • the disinfecting agent used which releases active chlorine is generally a solid chlorine product, most often a sodium or potassium salt of dichloroisocyanuric acid.
  • an anhydrous sodium dichloroisocyanurate titrating 63% active chlorine has been used in practice, or a sodium dihydrate dichloroisocyanurate titrating 56% active chlorine, or an anhydrous potassium dichloroisocyanurate titrating 59% active chlorine, either a potassium dichloroisocyanurate monohydrate titrating 56% active chlorine, or a calcium dichloroisocyanurate tetrahydrate titrating 56% active chlorine.
  • Active chlorine is defined as the oxidizing power due to positive chlorine.
  • the chlorinated agent which is a chlorinated trione triazine
  • the chlorinated agent is coated with phthalic diester acid or adipinic acid.
  • American patent US Pat. No. 3,703,470 proposes the coating of nonionic and anti-foaming surfactants with synthetic resins in order to avoid their reaction with chlorinated agents.
  • the chlorinated agent which is trichloroisocyanuric acid is stabilized using olefins having a tertiary carbon on a double bond, such as terpenes.
  • Polyethylene waxes have been found to be compatible with trichloroisocyanuric acid. In addition, they allow using relatively low doses to obtain good acid stabilization. Furthermore, they are dispersible under washing conditions, that is to say in aqueous media having a temperature of 50 to 65 ° C.
  • Polyethylene waxes are used in an amount of 0.5 to 10% by weight relative to the trichloroisocyanuric acid and preferably in an amount of 3 to 5% by weight. Beyond 5% of the difficulties for the implementation of the coating appear and it is necessary to adjust the conditions of the coating.
  • the laundry compositions which are the subject of the invention are produced by first coating the trichloroisocyanuric acid with the aid of polyethylene waxes.
  • This coating is carried out in any industrial mixer, such as a drum mixer, preferably a mixer provided with a heating device. It is also possible to use a rotary mixer of the concrete mixer type in which the molten wax is sprayed on the acid heated to a temperature close to 50 ° C. The processing temperature allows a good distribution of polyethylene waxes which solidify on cooling.
  • the wax-coated trichloroisocyanuric acid is then mixed in another mixer with the other constituents of the detergent.
  • the amounts of the various constituents used for the manufacture of the new detergent compositions which are the subject of the invention are used in conventional weight ratios.
  • the softening agent chosen from polyphosphates is used in an amount of 25 to 60% by weight and preferably from 40 to 50% by weight relative to the weight of the composition.
  • the alkanizing agent chosen from sodium salts containing sodium metasilicate is used in an amount of 30 to 70% by weight and preferably from 40 to 60% by weight relative to the weight of the composition.
  • the sodium silicate can be partially replaced by sodium carbonate, sodium sulphate or soda.
  • the nonionic surfactant is used in an amount of 0.5 to 4% by weight and preferably in an amount of 1 to 3% by weight relative to the weight of the composition
  • the trichloroisocyanuric acid coated with the using polyethylene waxes is used in an amount of 0.5 to 5% by weight and preferably 1 to 3% by weight relative to the weight of the composition.
  • the sodium tripolyphosphate is premixed with the nonionic surfactant in a rotary type mixer. After 20 minutes a homogeneous mixture is obtained. The metasilicate is then added to the mixer and after 20 minutes the coated trichloroisocyanuric acid is added. The assembly is then left in the rotating mixer for 20 minutes. The percentage of chlorine dosed by iodometry in the detergent composition is then 1.65%.
  • Table 1 shows the results obtained after 80 days of storage for detergent compositions prepared either from anhydrous sodium metasilicate, or from sodium metasilicate pentahydrate and from trichloroisocyanuric acid coated with waxes. polyethylene used in variable percentages (by weight). Chlorine results remaining are expressed as percentages relative to the initial chlorine.
  • Example 1 is repeated using trichloroisocyanuric acid coated with various quantities of polyethylene waxes and the determination of the remaining chlorine is carried out after 70 days of storage.
  • Table 2 summarizes the results obtained.
