Definitions

  • the present invention relates to bleaching compositions, in particular to hypochlorite bleaching compositions, suitable for use in laundry applications such as hand and machine laundry methods.
  • Bleaching compositions are well-known in the art. Amongst the different bleaching compositions available, those relying on bleaching by hypohalite bleaches such as hypochlorite are often preferred, mainly for performance reasons, especially at lower temperature.
  • hypochlorite based-compositions a problem encountered with the use of hypochlorite based-compositions is the resulting damage and/or yellowing of the fabrics being bleached.
  • hypohalite-containing composition suitable for use in laundry applications, which provides improved fabric whiteness to fabrics treated therewith.
  • pH buffering components such as silicates have been incorporated in hypochlorite compositions.
  • a typical disclosure can be found in EP-A-0,653,483.
  • compositions of the invention are chemically stable.
  • chemically stable it is meant that the hypohalite bleaching compositions of the present invention should not undergo more than 15% loss of available chlorine after 5 days of storage at 50°C ⁇ 0.5°C.
  • the % loss of available chlorine may be measured using the method described, for instance, in “Analyses des Eaux et Extraits de Javel” by "Lachner syndicalerance de L'eau de Javel et des building connexes", pages 9-10 (1984). Said method consists in measuring the available chlorine in the fresh compositions, i.e. just after they are made, and in the same compositions after 5 days at 50°C.
  • compositions of the invention are suitable for the bleaching of different types of fabrics including natural fabrics (e.g., fabrics made of cotton, viscose, linen, silk and wool), synthetic fabrics such as those made of polymeric fibers of synthetic origin as well as those made of both natural and synthetic fibers.
  • natural fabrics e.g., fabrics made of cotton, viscose, linen, silk and wool
  • synthetic fabrics such as those made of polymeric fibers of synthetic origin as well as those made of both natural and synthetic fibers.
  • the compositions of the present invention may be used on synthetic fibers despite a standing prejudice against the use of hypohalite bleaches, especially hypochlorite bleaches, on synthetic fibers, as evidenced by warning on labels of commercially available hypochlorite bleaches and clothes.

  • Hypohalite bleaches may be provided by a variety of sources, including bleaches that are oxidative bleaches and subsequently lead to the formation of positive halide ions as well as bleaches that are organic based sources of halides such as chloroisocyanurates.
  • Suitable hypohalite bleaches for use herein include the alkali metal and alkaline earth metal hypochlorites, hypobromites, hypoiodites, chlorinated trisodium phosphate dodecahydrates, potassium and sodium dichloroisocyanurates, potassium and sodium trichlorocyanurates, N-chloroimides, N-chloroamides, N-chloroamines and chlorohydantoins.
  • the preferred hypohalite bleaches among the above described are the alkali metal and/or alkaline earth metal hypochlorites selected from the group consisting of sodium, potassium, magnesium, lithium and calcium hypochlorites, and mixtures thereof, more preferably the alkali metal sodium hypochlorite.
  • the preferred hypohalite bleaches among the above described are the alkali metal and/or alkaline earth metal hypochlorites selected from the group consisting of lithium hypochlorites, calcium hypochlorites, chlorinated trisodium phosphate dodecahydrates, potassium dichloroisocyanurates, sodium dichloroisocyanurates, potassium trichlorocyanurates, sodium trichlorocyanurates, and mixtures thereof, more preferably sodium dichloroisocyanurates and/or calcium hypochlorite.

  • the liquid compositions according to the present invention comprise said hypohalite bleach such that the content of active halide in the composition is of from 0.1% to 20% by weight, more preferably from 2% to 8% by weight, most preferably from 3% to 6% by weight of the composition.
  • the solid compositions according to the present invention comprise said hypohalite bleach such that the content of active halide in the composition is of from 20% to 95% by weight, more preferably from 25% to 60% by weight of the composition.
  • a pH buffering component is another essential component for the compositions of the invention.
  • the pH buffering component ensures that the pH of the composition is buffered to a pH value ranging from 7.5 to 13, preferably from 8 to 12, more preferably from 8.5 to 11.5 after the composition has been diluted into 1 to 500 times its weight of water.

  • the other essential component of the invention is an ingredient having the ability to prevent the precipitation of the salts of said buffering component upon dilution of the composition in water. That ingredient, by preventing the precipitation of the salts of said buffering component upon dilution of the composition in water, has surprisingly been found to provide a reduction of the yellowing of the fabrics treated therewith, i.e. improved whiteness, as well as providing improved fabric safety.
  • the ingredient having the ability to prevent the precipitation of the salts of said buffering component upon dilution of the composition in water has to be stable to the hypohalite bleach.

The solution is maintained at 40°C for 30 min. The precipitates formed are separated from said solution and then dried and weighted. By “separating the precipitates formed”, it is meant to filter said solution with an apparatus comprising a peristaltic pump, a vacuum flask and a filter with 0.45 microns porosity.
  • Preferred ingredients are those substantially maintaining their ability to prevent the precipitation of the salts of said buffering component, as defined above, upon dilution of the composition in water after storage in an oven as defined by the oven test method below:
  • the two compositions defined in the test method above are stored in an oven (Memmert®) at 50°C for 7 days. After storage, the above test method is repeated, i.e. for each composition 10 ml of the composition is taken and added to 1 litre of tap water (30°F(French Degree)). The solution is maintained at 40°C for 30 min. The precipitates formed are separated from said solution and then dried and weighted.
  • compositions may also be assessed for their whitening effect and/or safety on the treated fabrics.
  • the whitening effect, i.e. the yellowing-prevention effect, and /or safety effect of the present invention can be evaluated by comparing the composition according to the present invention to the same composition without the ingredient having the ability to prevent the precipitation of the salts of said buffering component upon dilution of the composition in water.
  • the degree of yellowing can be determined by both visual and instumental grading. Visually, the difference in yellowing between items treated with different compositions can be determined by a team of expert panellists. Instrumentally, the assessment can be determined with the help of Colorimeters such as Ganz Griesser® instruments (e.g., Datacolor® Spectraflash® SF 500, Machbet White-eye® 500) or a ZEISS ELREPHO® or others which are available for instance from Hunterlab® or Gardner®.
