Definitions

  • the present invention relates to the use of partially cationically substituted quaternary ammonium polymers, in laundry processes, for dye fixing benefits in textiles.
  • Dye fixers are widely used as a treatment in the textile industry, and are known in consumer laundry products. However, whilst these commercial materials can provide a substantial reduction in dye loss, the structural requirements for effectiveness result in an unacceptable environmental profile. Specifically, effective commercial dye fixers are relatively low molecular weight polymers with a high degree of cationic charge. Dye fixing properties are known to become ineffective with decrease in cationic charge.
  • WO04056888 discloses polymeric dye fixers for laundry applications formed from cationic and hydrophobic unsaturated monomers.
  • WO9746650, WO9746651 , WO9746652 and WO9746654 all Procter and
  • Dye fixers in rinse products are also known from WO9812295 and WO9812296 (Procter and Gamble), which disclose specific amino-functional polymers with a dye fixer.

  • WO200131 1 16 discloses a fabric enhancer formulation comprising a dye fixer and solvent.
  • DE19643281 covers use of specified polycationic quaternised products as dye fixers in detergents or rinses.
  • Some partially cationically substituted quaternary ammonium polymers are already approved for use in laundry products for a variety of benefits, for example as deposition aids. We have now found that some of these materials have previously unrecognised dye fixing properties when delivered in the rinse. These materials have a lower level of cationic charge than conventional dye fixers, due to the presence of fewer quaternised groups per monomer unit which not only obviates the adverse ecotox properties but surprisingly also provides a significant dye fixing benefit, despite the lower cationic charge.

Examples of well known top-notes include citrus oils, linalool, linalyl acetate, lavender, dihydromyrcenol, rose oxide and cis-3-hexanol. Top notes typically comprise 15-25%wt of a perfume composition. Some or all of the perfume or pro-fragrance may be encapsulated. Typical perfume components which it is advantageous to encapsulate include those with a relatively low boiling point, preferably those with a boiling point of less than
  • perfume components which have a low Clog P (i.e. those which will be partitioned into water), preferably with a Clog P of less than 3.0.
  • Clog P i.e. those which will be partitioned into water
  • materials, of relatively low boiling point and relatively low Clog P have been called the "delayed blooming" perfume ingredients and include the following materials: Allyl Caproate, Amyl Acetate, Amyl Propionate, Anisic Aldehyde, Anisole,
  • Preferred non-encapsulated perfume ingredients are those hydrophobic perfume components with a ClogP above 3.
  • ClogP means the logarithm to base 10 of the octanol/water partition coefficient (P).
  • octanol/water partition coefficient of a perfume raw material is the ratio between its equilibrium concentrations in octanol and water. Given that this measure is a ratio of the equilibrium concentration of a PRM in a non-polar solvent (octanol) with its concentration in a polar solvent (water), ClogP is also a measure of the hydrophobicity of a material-the higher the ClogP value, the more
  • ClogP values can be readily calculated from a program called "CLOGP" which is available from Daylight Chemical Information Systems Inc., Irvine Calif., USA. Octanol/water partition coefficients are described in more detail in U.S. Pat. No. 5,578,563.
  • Perfume components with a ClogP above 3 comprise: Iso E super, citronellol, Ethyl cinnamate, Bangalol, 2,4,6-Trimethylbenzaldehyde, Hexyl cinnamic aldehyde, 2,6-Dimethyl-2-heptanol, Diisobutylcarbinol, Ethyl salicylate, Phenethyl isobutyrate, Ethyl hexyl ketone, Propyl amyl ketone, Dibutyl ketone, Heptyl methyl ketone, 4,5-Dihydrotoluene, Caprylic aldehyde, Citral, Geranial, Isopropyl benzoate, Cyclohexanepropionic acid, Campholene aldehyde, Caprylic acid, Caprylic alcohol, Cuminaldehyde, 1 -Ethyl-4-nitrobenzene, Heptyl formate,
  • perfumes it is envisaged that there will be four or more, preferably five or more, more preferably six or more or even seven or more different perfume components from the list given of delayed blooming perfumes given above and/or the list of perfume components with a ClogP above 3 present in the perfume.
  • Another group of perfumes with which the present invention can be applied are the so-called 'aromatherapy' materials. These include many components also used in perfumery, including components of essential oils such as Clary Sage, Eucalyptus, Geranium, Lavender, Mace Extract, Neroli, Nutmeg, Spearmint, Sweet Violet Leaf and Valerian.

  • Example 2 Treatment of cloths with Composition 1 and Comparative Examples A-D
  • a multi-wash experiment was conducted using Tergo washes using the following protocol :- Three woven cotton cloths measuring 15 x 15 cm, dyed with Direct Green 26 dye (specifically woven mercerised cotton, dyed with 1 .5% Solophenyl Green BL, with a resin finish), and three undyed white woven cotton cloths were placed in a Tergotometer. A wash, followed by two water rinses and a final treatment rinse were performed. In the final treatment rinse, fabric conditioner and cationic polymer (1 %) were added separately over the side.
  • Dye fixation levels in the cloths treated in Example 2 above were measured by reflectance (Delta E at 420 nm).
  • the reflectance measurement was carried out using an Ultrascan XE to measure Delta E at 420 nm, with a UV filter in place. Delta E measurements were taken for the white cloths to give a measure of the amount of green dye that had transferred to the white fabric.
  • results are shown in Table 4 below.
  • the results are shown as differences from standard fabric conditioner, with a positive value indicating a benefit.
  • a lower score corresponds to reduced dye pick up, so indicates a better result.
