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 andlor yellowing of the fabrics being bleached.
  • hypohalite-containing composition suitable for use in laundry applications, which provides improved fabric whiteness to fabrics treated therewith.
  • 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 "Lacel syndicateInstitut 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.
  • the present invention is a liquid bleaching composition
  • a liquid bleaching composition comprising
  • a solid bleaching composition comprising:
  • the present invention also encompasses the use, in a hypohalite bleaching composition of an aminophosphonic and/or phosphonic modified polymer as described herein, for providing improved fabric whiteness andlor safety to the fabrics treated therewith.
