Description

P0000183 EP CPL SUBSTRATE TREATMENT COMPOSITIONS FIELD OF THE INVENTION The present disclosure relates to substrate treatment compositions, such as hard and 5 fabric care compositions for dye transfer inhibition. BACKGROUND OF THE INVENTION When treating substrates such as fabrics, dye transfer can cause challenges. For example, dye from one portion of a fabric may become released in a wash liquor and may 10 then deposit on a different portion of the fabric, or on a different fabric altogether. Transfer of such dyes (known as "fugitive dyes") can cause greying of fabrics, especially of those of a light or white colour. Cotton, polyester, poly /cotton, and nylon fabrics are particularly good acceptor fabrics for 15 fugitive dye, and over multiple wash cycles, fugitive dye re-deposition results in bright and lightly coloured clothes appearing dull or faded over time. This problem is particularly difficult to solve in the consumer home since typical wash loads contain mixed fabric types and colours that will have multiple sources of fugitive dyes that can be soluble in the wash liquor (eg. direct dyes, hydrolyzed or oxidised reactive dyes, poorly fixed dye 20 from the manufacturing process), or insoluble in the wash liquor (eg. particulate or vat dyes). Thus, there remains a problem of dye transfer during the wash. 25 Certain polymers, generally known as dye transfer inhibitor ("DTI") polymers, have traditionally been used in laundry compositions to address the dye transfer problem. Such polymers include polyvinyl pyrrolidone (PVP), poly(vinylpyridine-N-oxide) (PVNO), polyvinylpyrrolidone-co-polyvinylimidazole (P VP/P VI), and poly(vinylpyrrolidone)co- poly(vinylpyridine-N-oxide) (PVP/PVNO) polymers, which have typically included 30 relatively high levels of vinyl pyrrolidone ("VP"). These traditional DTI polymers are quite effective at inhibiting the transfer of direct dyes, which are dyes that are used to dye cellulosic fibers that are known to have poor wash fastness resulting in dye bleeding during the wash process. P0000183 EP CPL However, traditional DTI polymers can lead to stability challenges in combination with other laundry adjuncts, such as optical brighteners. Thus, particularly as direct dyes have become less prevalent in typical laundry loads, traditional DTI polymers are only effective on a small portion of the garments in the wash load, and consumers continue to have a 5 problem with dye transfer even with detergents that contain traditional DTI polymers. This challenge may be made even more acute by the laundry practices of the modem consumer, including larger loads that tend to have mixed fabric types and colours (e.g., under-sorted loads). 10 Cellulase enzymes are known to release dye from unwashed denim to give denim an uneven dye appearance, or so-called "worn" look on denim. Consumers typically want to keep this "just purchased" look of their denim, even after washing multiple times. High cellulase levels in detergent composition can result in the unintended fading of the garment that may also compound the dye transfer negative that can occur in mixed colour 15 loads. Therefore, there remains a need for improved, stable laundry compositions and related processes that can inhibit dye transfer, particularly transfer of particulate dyes. Another problem which may be apparent to consumers is unattached reactive dye eg. 20 from hydrolysed, oxidation or poor fixing during manufacturing process this will be more prevalent with newer garments where potential is greater or as a low level of dye transfer over multiple washed resulting in gradual discolouration of articles. SUMMARY OF THE INVENTION 25 The present disclosure attempts to solve one or more of the aforementioned needed by providing fabric treatment compositions that include particular compounds useful for dye transfer inhibition (also known as dye control), and related processes.

Example betaine-functionalised structures below:

wherein; 10 R is alkyl having 8 to 22 carbon atoms; R¹, R², R³, and R⁴ are independently selected from the group consisting of: and H, wherein 3 or more of the R groups R¹, R², R³, and R⁴ are 15 and P0000183 EP CPL

wherein; R is alkyl having 8 to 22 carbon atoms; 5 R⁵, R⁶, R⁷, R⁸; R⁹, R¹⁰ and R¹¹ are independently selected from the group consisting of

and H, wherein 3 or more of the R groups R⁵, R⁶, R⁷, R⁸; R⁹, R¹⁰ and R¹¹ are

10 In a preferred embodiment R is alkyl having 8 to 22 carbon atoms. Without wishing to be bound by theory, it is believed that by increasing the number of betaine moieties in accordance with the present disclosure, a fabric care composition that includes such betaine-functionalised compounds may provide improved dye control 15 during fabric treatment processes, such as wash or rinse cycles. Method of making the betaine functionalised APGs. To make a betaine-functionlised APG, the APG is first amino-functionalised by reacting chloroethanolamine Cl-CH₂-CH(OH)CH₂-N-(CH₂CH₂OH)₂ P0000183 EP CPL with APG according to the reaction below:

The amino-APG is then reacted with sodium chloro acetate as follows

5 Betaine functionality is increased by either of : a) In the first amination step, increasing the amount of chloroethanolamine which is reacted onto the alkyl polyglucoside and b) In the second step, increasing the amount of the choloracetic acid so increasing 10 betaine functionality on the resultant polymer Examples Alkyl Glycosides are raw materials used to make the surface-active polyglycoside derivatives of the present invention. 15 Saccharides useful in the process of making alkyl glycosides are saccharides that can be alkylated in the "1" position, commonly referred to as "reducing saccharides", or higher saccharides that can be hydrolyzed to provide such a saccharide. These saccharides are typically comprised of aldo- or keto-hexoses or pentoses. P0000183 EP CPL Examples of saccharides include glucose (dextrose), fructose, mannose, galactose, talose, allose, altrose, idose, arabinose, xylose, lyxose, and ribose. Examples of hydrolyzable saccharides that are a source of reducing saccharides include starch, maltose, sucrose, lactose, maltotriose, xylobiose, mellibiose, cellobiose, raffinose, 5 stachiose, methyl glycosides, butyl glycosides, levoglucosan, and 1,6- anhydroglucofuranose. The physical form of the saccharide may vary. The saccharide will typically be in a fluid (as opposed to a solid) state, e.g. as a melt or an aqueous syrup, during at least a portion 10 of the period of reaction, if not for a predominant portion of the period of the reaction. Crystalline (e.g. anhydrous or hydrates) or amorphous saccharide solids in various particle sizes, e.g. granules, powders, etc., can be used, but the heating of the reaction medium may well fluidize at least a portion of a solid reactant, if not a predominant portion of the saccharide reactant. Aqueous syrups of saccharides, typically at saccharide solids 15 of between about 10 percent and 90 percent dry solids by weight can also be used. Indeed, the use of the hydrophobic catalysts of this invention should show the most improved results over conventional catalysts in the context of the use of aqueous syrup reactants as compared with processes which employ solid saccharide reactants, particularly with respect to avoiding the formation of deleterious amounts of 20 polysaccharides and very high DP alkyl glycosides during the glycoside formation reaction. The preferred saccharides are glucose, galactose, xylose and arabinose, or mixtures thereof, for reasons of availability, low cost, and convenience. Glucose in the anhydrous 25 crystalline form is preferred, although dextrose monohydrate, corn syrups of high dry solids (typically 50 percent to 80 percent dry solids) and a high dextrose equivalence (D.E.) (typically greater than 90 D.E and most commonly 95 D.E.) can be commonly employed. Indeed, while the higher the purity of the dextrose source, the better the quality of the product (other things being equal), the catalysts of this invention allow the use of a 30 lower purity dextrose source and yet yield a product of substantially equivalent quality as compared with prior catalysts. Because of the ready availability of glucose and its oligomers, much of the remaining description is particularly suited to the use of glucose in its various forms. P0000183 EP CPL Alcohols useful in the process of this invention are hydroxyl-functional organic compounds capable of alkylating a saccharide in the "I" position. The alcohol can be naturally occurring, synthetic, or derived from natural sources and/or derivatized. 5 Examples include monohydric alcohols (more fully discussed below) and polyhydric alcohols (e.g. ethylene glycol, propylene glycol, polyethylene glycols, polypropylene glycols, butylene glycol, glycerol, trimethylolpropane, pentaerythritol, polyester polyols, polyisocyanate polyols, and so on). Other examples include aromatic alcohols such as benzyl alcohol, phenol, substituted phenols (e.g. alkylphenols) and alkoxylates of each. 10 Preferred alcohols are monohydric alcohols containing from about 1 to about 30 carbon atoms. They may be primary or secondary alcohols, straight or branched chain, saturated or unsaturated (e.g. allyl alcohol, 2-ethylhexenyl alcohol and oleyl alcohol) alkyl or aralkyl alcohols, ether alcohols, cyclic alcohols, or heterocyclic alcohols. In general, these alcohols have minimal solvent power for the saccharide molecule. Examples of the 15 monohydric alcohols which may be employed in the present invention include methyl alcohol, isopropyl alcohol, butyl alcohol, octyl alcohol, nonyl alcohol, decyl alcohol, dodecyl alcohol, tridecyl alcohol, tetradecyl alcohol, pentadecyl alcohol, hexadecyl alcohol, pentacosyl alcohol, oleyl alcohol, linoleyl alcohol, isoborneol alcohol, hydroabietyl alcohol, phenoxyethanol, phenoxypolyethoxyethanol containing five ethoxy groups, 2- 20 methyl-7-ethyl-4-undecanol, and mixtures of one or more of the above. A preferred group of alcohols are alkanols having the formula ROH wherein R represents an alkyl group having from 8 to 30 carbon atoms. A particularly preferred group of alcohols are those wherein R represents an alkyl radical having from 8 to 20, preferably II to 18, carbon atoms. The alkyls can be straight or branched chain. 25 Alkyl Glycoside Examples Example 1 A one-liter, four-necked, round-bottomed flask was equipped through its centre neck with an overhead mechanical stirrer, through a second neck with a distillation head fitted with an addition funnel and a condenser/receiver/vacuum take-off assembly, through a third 30 neck fitted with a three hole rubber stopper with a capillary nitrogen bleed, a calibrated mercury thermometer and a vacuum tight temperature controller probe, and on the fourth neck with a septum for sampling. P0000183 EP CPL The flask was charged with 602.4 g (3.105 moles) of a commercial mixture of C₁₁ to C₁₅ (98 percent C₁₂ and C₁₃) straight and branched alkanols (Neodol 23 available form Shell Chemical Co.) and 136.6 g (0.69 moles) of a commercially available dextrose monohydrate (Staleydex 333, available from A. E. Staley Mfg. Co. at 9.0 percent 5 moisture). The slurry was heated at a vacuum of 30 mm Hg (absolute). Water was released starting at about 57 degrees centigrade and heating was continued until the slurry had reached 110 degrees centigrade At this time 3.2 g (0.00345 mole of a commercially available mixture of 50 percent dinonylnaphthalenesulfonic acid in heptane (available from King Industries) was added as a catalyst and the theoretical volume of 10 water distilled at about a linear rate over 8 hours. After stirring an additional hour, a stoichiometric amount of aqueous NaOH (33 percent in H₂O) was added. An aliquot of the neutralized reaction mixture (3.39 g, 1 g dissolved substance) was dissolved in a total volume of 10 ml with 1:1 isopropanol:water. The pH of this solution was 7.8. The remainder of the reaction mixture was evaporated to a clear melt at 200 degrees 15 centigrade and 1 mm pressure using a Leybold-Heraeus Distact.™. wiped film evaporator operating at a feed rate of 700 ml/hr. The residue was analyzed using a combination of gas and liquid chromatographic techniques as well as NMR spectroscopy and was shown to contain less than 0.2 percent free alcohol and less than 2 percent polar species (HPLC) and an NMR mole ratio of 20 glucose rings to fatty chains of about 1.4. Example 2–8 The same one-liter, four-necked, round-bottomed flask was equipped through its center neck with an overhead mechanical stirrer, through a second neck with a distillation head 25 fitted with an addition funnel and a condenser/receiver/vacuum take-off assembly, through a third neck fitted with a three hole rubber stopper with a capillary nitrogen bleed, a calibrated mercury thermometer and a vacuum tight temperature controller probe, and on the fourth neck with a septum for sampling. The flask was charged with 3.105 moles of the specified alcohol and 136.6 g (0.69 moles) 30 of a commercially available dextrose monohydrate (Staleydex 333, available from A. E. Staley Mfg. Co. at 9.0 percent moisture). The slurry was heated at a vacuum of 30 mm Hg (absolute). Water was released starting at about 57 degrees centigrade and heating was continued until the slurry had reached 110 degrees centigrade At this time 3.2 g P0000183 EP CPL (0.00345 mole of a commercially available mixture of 50 percent dinonylnaphthalenesulfonic acid in heptane (available from King Industries) was added as a catalyst and the theoretical volume of water distilled at about a linear rate over 8 hours. After stirring an additional hour, a stoichiometric amount of aqueous NaOH (33 percent in 5 H₂O) was added. An aliquot of the neutralized reaction mixture (3.39 g, 1 g dissolved substance) was dissolved in a total volume of 10 ml with 1:1 isopropanol:water. The pH of this solution was 7.8. The remainder of the reaction mixture was evaporated to a clear melt at 200 degrees centigrade and 1 mm pressure using a Leybold-Heraeus Distact.™. wiped film evaporator 10 operating at a feed rate of 700 ml/hr. The residue was analyzed using a combination of gas and liquid chromatographic techniques as well as NMR spectroscopy and was shown to contain less than 0.2 percent free alcohol and less than 2 percent polar species (HPLC) and an NMR mole ratio of glucose rings to fatty chains of about 1.4. The hydroxyl value was run on the resultant 15 product and is indicated below.

It will be clearly understood that the alkyl polyglycoside has on average five hydroxyl groups when the d.p. is 1.4. The phosphation can include all five, but in a more preferred embodiment includes between one and three hydroxyl groups. This ratio provides the 20 best degree of water solubility. The most preferred number of hydroxyl groups to amine is 2. P0000183 EP CPL Step A – making the amino-APG To a flask equipped with agitation, heat, thermometer and nitrogen sparge is added the specified amount of the specified alkyl polyglucoside and enough water to make the final product have a solids of 35 percent by weight. The alkyl polyglucoside is heated to melt. 5 Next, add the specified number of grams of chloro reactant Example 9 is added under good agitation and nitrogen sparge. Next is added 0.5 percent sodium methylate. The percent is by weight and is based upon the total amount of all materials reacted. Nitrogen sparge is simply nitrogen bubbled through the liquid contents of the flask. This keeps the colour light, minimizing oxidation and colour formation. The reaction mass is heated to 10 90–100 degrees centigrade, and is held for 5–8 hours. Testing for the concentration of Chloride ion follows the reaction progress. Once the theoretical value is reached, the reaction is terminated and the product is used without additional purification.

Preferably the amount of choloracetic acid used is more than 200g, more preferably more 15 than 300g, more preferably more than 400g, most preferably more than 700g. Step B Preparation of the Betaine Example 18–25 Method: to a flask equipped with agitation, heat, thermometer and nitrogen sparge is added the entire product of examples for the amino alkyl polyglucoside having a solids of 20 35 percent by weight (examples 10–17). The solution is heated to melt. Next, add the specified number of grams of sodium chloro acetate is added under good agitation and nitrogen sparge. Nitrogen sparge is simply nitrogen bubbled through the liquid contents of the flask. This keeps the colour light, minimizing oxidation and colour formation. The reaction mass is heated to 90–100 degrees centigrade, and is held for 5–8 hours. Testing P0000183 EP CPL for the concentration of chloride ion follows the reaction progress. Once the theoretical value is reached, the reaction is terminated, and the product is used without additional purification. 5 Reaction with Sodium Chloroacetate.

Preferably the amount of Sodium Chloroacetate reacted is more than 100g, more preferably more than 200g. 10 Without wishing to be bound by theory, it is believed that by carefully increasing the number of betaine moieties in accordance with the present disclosure, a fabric care composition that includes such betaine-functionalised compounds may provide improved dye control during fabric treatment processes, such as wash or rinse cycles. 15 Treatment Adjuncts The compositions of the present disclosure may include a treatment adjunct. The treatment adjuncts may be suitable for delivering a treatment benefit to a target surface, such as a fabric or other textile. Treatment adjuncts, as used herein, may also include agents that facilitate chemical or physical stability in the treatment compositions, such as 20 buffers, structurants/thickeners, and/or carriers.
