Definitions

  • the present invention relates to the photo-bleaching of products, in particular laundry bleaching.
  • a substrate such as a laundry fabric or other textile is subjected to hydrogen peroxide, or to substances which can generate hydroperoxyl radicals, such as inorganic or organic peroxides.
  • a preferred approach to generating hydroperoxyl bleach radicals is the use of inorganic peroxides coupled with organic precursor compounds. These systems are employed for many commercial laundry powders. For example, various European systems are based on tetraacetyl ethylenediamine (TAED) as the organic precursor coupled with sodium perborate or sodium percarbonate, whereas in the United States laundry bleach products are typically based on sodium nonanoyloxybenzenesulphonate (SNOBS) as the organic precursor coupled with sodium perborate.
  • TAED tetraacetyl ethylenediamine
  • SNOBS sodium nonanoyloxybenzenesulphonate
  • hydrogen peroxide and peroxy systems can be activated by bleach catalysts, such as by complexes of iron and the ligand N4Py (i.e. N, N-bis (pyridin-2-yl-methyl) - bis (pyridin-2-yl) ethylamine) disclosed in W095/34628.
  • radical photo-initiators which are generally organic chemicals which on absorption of light, particularly UV light, form reactive radicals. They are widely used to initiate the polymerisation of alkenes and thereby cure coatings. They may also be used as photobleach agents as discussed in GB 9917451. Radical photoinitiators, in general, are discussed by H.F. Gruber in Prog. Polym . Sci . Vol 1 7. 953-1044.
  • a bleaching composition comprising a photo-reactive red dye having a lambda max in the visible in the range 500 to 550 nm together with a blue dye having a lambda max in the visible in the range 580 to 640 nm yields a bleached textile with enhanced whiteness.
  • the bleaching activity is particularly good against catechol-type stains, polyphenolics-type stains and polycyclic hydroxylated aromatic-type stains.
  • catechol-type stains polyphenolics-type stains and polycyclic hydroxylated aromatic-type stains are as a result of the chromophores found in tea, coffee, blackberry, blueberry, blackcurrant, red wine, banana and the like.
  • stains are. characteristic and distinct from oily food type stains such as tomato oil stain, curry oil stain, mango stain, annatto derived stain, colorau derived stain, and sebum derived stain etc.
  • the present invention provides a bleaching composition
  • a bleaching composition comprising: a) from 0.0001 to 0.1 wt/wt% of a photo-reactive red dye having a peak in the visible in the range 500 to 550 nm; b) from 0.0001 wt/wt% to 0.1 wt/wt of a blue dye lambda max 580-640 nm; c) from 0 to 40 wt/wt% other bleaching species; and, d) the balance carriers and adjunct ingredients to 100 wt/wt % of the total bleaching composition.
  • a wash liquor having a pH in the range 8 to 11 is provided.
  • the bleaching composition may be used on its own or in conjunction with other bleaching species. It is preferred that those other bleaching species, if used, possess different bleaching profiles to the solely the photo- reactive red dye bleaching composition.
  • the stain bleaching profile of known photo-bleaches such as radical photoinitiators, is generally that of ceretenoid type stains, for example tomato stains which is similar to the bleaching profile of ⁇ air" bleaching catalysts.
  • Xanthene type dyes are preferred, particularly based on the structure:
  • the dye may be substituted by halogens and other elements/groups.
  • Particularly preferred examples are Food red 14 and Rose Bengal, Phloxin B, Eosin Y.
  • Food red 14 is used solely as the bleaching species the consumer is reassured in the laundry context that the bleach used is mild because of that fact that it is an acceptable food additive.
  • Food dyes are used to enhance the visual appearance of many foods. As humans consume them, they undergo rigorous testing and examination to ensure they represent no risk to health.
  • the present invention also extends to a method of photo- bleaching a textile.
  • the light used for photo-bleaching may be sunlight, florescent light or that from an ordinary light bulb.
  • Photo-bleaching is still effective where the concentration of the photo-reactive red dye on the textile/cloth is so low as to be barely perceptible to the human eye. It is preferred that the dye rapidly photo-fades on irradiation with light.
  • suitable pre- treatment means for application include sprays, pens, roller-ball devices, bars, soft solid applicator sticks.
  • a unit dose as used herein is a particular amount of the bleaching composition used for a type of wash.
  • the unit dose may be in the form of a defined volume of powder, granules or tablet.
  • a photo-reactive dye is one which on exposure to light in the wavelength range 300-700nm, more preferably 400 to 700 nm, undergoes photochemical process to produce reactive/excited species that is capable of bleaching coloured stained material, such as tea stains.
  • the photo- reaction should be able to occur in minutes to hours under normal lighting conditions (40-400 W rrf 2 in the 400 to 700 nm range) .

  • Direct and acid dyes may be selected from azo, bis-azo, anthraquinone, triarylmethane dyes.
  • Preferred dyes are clearly those that deposit on cotton.
  • Preferred direct and acid dyes are those that deposit on cotton but do not build up on cotton. over multiple washes, examples of dyes that do not build up are acid black 1, acid blue 29, acid blue 113, and acid black 24.
  • Particularly preferred are dyes, which deposit on cotton but do not deposit on nylon, such as acid black 1 and acid blue 29.
  • the blue dye also serves to mask any residual red colour, the combination or red and blue providing a violet colour that enhances the whiteness of the fabric.
  • the preferred photo-reactive red dye is Food red 14 (Erythrosine B) (E 127; CI number 45430) (CAS 16423-68-0) which is a widely used red food colouring, see Hunger K. Industrial Dyes: Chemistry Properties And Applications. Wiley-VCH, Heidelberg 2003.
