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.

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.

• ingredients include further preservatives (e.g. bactericides), pH buffering agents, perfume carriers, hydrotropes, anti-redeposition agents, soil- release agents, polyelectrolytes, anti-shrinking agents, anti-wrinkle agents, antioxidants, sunscreens, anti-corrosion agents, drape imparting agents, anti-static agents, ironing aids, silicones, antifoams, colourants, pearlisers and/or opacifiers, natural oils/extracts, processing aids, e.g. electrolytes, hygiene agents, e.g. anti- bacterials and antifungals, thickeners and skin benefit agents.
• compositions for use in the present invention are preferably rinse-added softening compositions.
• compositions have a pH ranging from about 2.5 to 6, preferably from about 2.5 to 4.5, most preferably about 2.5 to 2.8.
• compositions for use in the invention may also contain pH modifiers such as hydrochloric acid or lactic acid.
• a composition for use in the invention is preferably in liquid form.
• composition may be a concentrate to be diluted in a solvent, including water, before use.
• the composition may also be a ready-to-use (in-use) composition.
• the composition is provided as a ready to use liquid comprising an aqueous phase.
• the aqueous phase may comprise water-soluble species, such as mineral salts or short chain (Ci -4 ) alcohols.
• the composition is preferably for use in the rinse cycle of a home textile laundering operation, where, it may be added directly in an undiluted state to a washing machine, e.g. through a dispenser drawer or, for a top-loading washing machine, directly into the drum. Alternatively, it can be diluted prior to use.
• the compositions may also be used in a domestic hand-washing laundry operation. It is also possible for the compositions of the present invention to be used in industrial laundry operations, e.g. as a finishing agent for softening new clothes prior to sale to consumers.
• Fabric conditioner compositions for use in the invention may typically be made by combining a melt comprising the fabric softening active and co-softener with an aqueous phase. Further components may be combined with the water phase, or may be post dosed into the composition after combination of the melt and water phase.
• Examples of the invention are represented by a number. Comparative examples are represented by a letter.
• Example 1 Fabric conditioner and polymers used for the treatment of fabric
• composition of the fabric conditioner is given in Table 1 below:- Table 1 : Fabric conditioner composition
• polysaccharide/guar gum 1 LR400 is a partially cationically substituted quaternary ammonium material in accordance with the invention, specifically a polyquaternium 10 compound. It is a cellulose ether with a-[2-hydroxy-3-(trimethylammonio)propyl]-w- hydroxypolypoly(oxy-1 ,2-ethanediyl) chloride. It has a linear polysaccharide structure.
• N-HanceTM BF 13 is a partially cationic substituted quaternary ammonium material outside the scope of the invention.
• Guar gum has a branched polysaccharide structure.
• the polymers were used as a 1 % solution of polymer in water.
• 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.
