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 chlorinated product, most often a sodium or potassium salt of dichloroisoeyanuric acid.
- an anhydrous sodium dichloroisocyanurate titrating 63% of active chlorine or a dichloroisocyanurate; sodium dihydrate titrating has been used. 56% active chlorine, i.e. an anhydrous potassium dichloroisocyanurate titrating 59% active chlorine, or 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.
- positive chlorine corresponds to, it should be remembered that the chlorine present in the chlorinated derivatives described above is fixed on the nitrogen atom and is found there in the form of the degree of oxidation + 1, c is C1 + .
- C1 + a degree of oxidation + 1
- un.ion C1 + combines with two electrons to pass to the C1 (chloride) stage.
- Two equivalents of oxidants are released which correspond to 71 g of elemental chlorine although the atomic mass is only 35.5. This also means that an atom of C1 + has the same oxidizing power as a molecule of elementary chlorine Cl2.
- the present invention relates to a new detergent composition suitable for washing dishes in a washing machine containing a softening agent chosen from polyphosphates, an alkalizing agent chosen from sodium salts, containing sodium metasilicate, a surfactant non-ionic and a chloroisocyanuric derivative characterized in that the chloroisocyanuric derivative used is trichloroisocyanuric acid coated with a polyethylene wax used in an amount of 0.5 to 10% by weight relative to the weight of the acid.
- polyethylene waxes are compatible with trichloroisocyanuric acid.
- they allow using relatively low doses to obtain good acid stabilization.
- they are dispersible under washing conditions, that is to say in aqueous media having a temperature of 50 to 65 ° C.
- Polyethylene waxes are made up of polyethylenes having an average molecular weight of around 2,500, a low melting point below 70 ° C, a dropping point of 70 to 80 ° C and a density of 0.86 to 0, 88. They 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 the polyethylene waxes which are solidify on cooling.
- the wax-coated trichloroisocyanuric acid is then mixed in another mixer with the other constituents of the lye.
- 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 alkalizing agent chosen from sodium silicates 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. In known manner sodium silicate can be partially replaced by sodium carbonate, sodium ulfate or soda.
- the nonionic surfactant is used in an amount of 0.5 to 4% by weight and preferably 1 amount of 1 to 3% by weight relative to the weight of the composition.
- the trichloroisocyanuric acid coated with 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.
- Table 1 shows the results obtained after 80 days of storage for laundry 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). The results concerning the remaining chlorine are expressed in percentages compared 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.
