Description

P0000182 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. P0000182 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.

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 carefully selecting the number of betaine moieties in accordance with the present disclosure, a fabric care 10 composition that includes such betaine-functionalised compounds may provide improved dye control 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 15 chloroethanolamine Cl-CH2-CH(OH)CH2-N-(CH2CH2OH)2 with APG according to the reaction below:
Figure imgf000015_0003
The amino-APG is then reacted with sodium chloro acetate as follows P0000182 EP CPL
Figure imgf000016_0001
Betaine functionality is controlled by either of : a) In the first amination step, restricting the amount of chloroethanolamine which is 5 reacted onto the alkyl polyglycoside and/or b) In the second step, restricting the amount of the choloracetic acid so producing ethanolamine and betaine functionality on the resultant polymer Examples Alkyl Glycosides are raw materials used to make the surface-active polyglycoside 10 derivatives of the present invention. 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 15 typically comprised of aldo- or keto-hexoses or pentoses. 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,20 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 P0000182 EP CPL 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 5 of the saccharide reactant. Aqueous syrups of saccharides, typically at saccharide solids 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, 10 particularly with respect to avoiding the formation of deleterious amounts of polysaccharides and very high DP alkyl glycosides during the glycoside formation reaction. The preferred saccharides are glucose, galactose, xylose and arabinose, or mixtures 15 thereof, for reasons of availability, low cost, and convenience. Glucose in the anhydrous 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 20 of the product (other things being equal), the catalysts of this invention allow the use of a 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. 25 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. Examples include monohydric alcohols (more fully discussed below) and polyhydric 30 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. P0000182 EP CPL 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 5 alcohols have minimal solvent power for the saccharide molecule. Examples of the 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, hydroabietyl10 alcohol, phenoxyethanol, phenoxypolyethoxyethanol containing five ethoxy groups, 2- 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 15 to 18, carbon atoms. The alkyls can be straight or branched chain.

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 5 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 10 glucose rings to fatty chains of about 1.4.

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 5 embodiment includes between one and three hydroxyl groups. This ratio provides the best degree of water solubility. The most preferred number of hydroxyl groups to amine is 2. Step A – making the amino-APG 10 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.
