The present invention relates to a detergent composition comprising a detersive surfactant and a grafted polymer.

Description

[Technical Field]

[0001] The present invention relates to a detergent composition comprising a detersive surfactant and a novel graft polymer, the novel graft polymer comprising a copolymer backbone (A) as a graft base, having polymeric side chains (B) grafted to the copolymer backbone (A). The polymeric side chains (B) can be obtained by polymerization of at least one vinyl ester monomer (B1) and optionally further monomers (B2), where the weight ratio of monomer (B2) to monomer (B1), if present, is less than 0.5. The polymer backbone (A) can be obtained by polymerization of ethylene oxide, and the molecular weight Mn (g / mol) of the polymer backbone is in the range of 500 to 5,000. [Background technology]

[0002] Initiatives to ban microplastics, particularly in cosmetic products, have already been introduced in various states. In addition to this ban on insoluble microplastics, there is intense discussion about future requirements for soluble polymers used in consumer products. Therefore, identifying new, well-biodegradable components for such applications is highly desirable. This problem is primarily acute for polymers produced by radical polymerization based on carbon-only backbones, since carbon-only backbones (those without heteroatoms such as oxygen) are particularly difficult to degrade by microorganisms. Even industrially important radical-generated graft polymers with polyethylene glycol backbones exhibit limited biodegradability in wastewater. However, the polymers described in this invention, preferably produced by radical graft polymerization, offer enhanced biodegradability compared to the state of the art.

[0003] WO 2007 / 138053 discloses amphiphilic graft polymers based on a water-soluble polyalkylene oxide (A) as a graft base and side chains formed by polymerization of a vinyl ester component (B), the polymers having an average grafting site of less than 1 per 50 alkylene oxide units and an average molar mass M of 3,000 to 100,000. However, WO 2007 / 138053 only identifies the "water-soluble polyalkylene oxide" as the backbone and does not contain any disclosure regarding the biodegradability of the respective graft polymers disclosed therein.

[0004] WO 03 / 042262 relates to a graft polymer comprising (A) a polymeric graft backbone free of monoethylenically unsaturated units and (B) polymeric side chains formed from a copolymer of two different monoethylenically unsaturated monomers (B1) and (B2), each of which contains a nitrogen-containing heterocycle, whereby the amount of side chains (B) accounts for 35 to 55% by weight of the total polymer. However, the graft polymer according to WO 03 / 042262 is not based on vinyl ester monomers in each polymeric side chain grafted onto the backbone. Other than that, WO 03 / 042262 does not disclose any information related to the biodegradability of the graft polymers disclosed therein.

[0005] U.S. Patent No. 5,318,719 relates to a new class of biodegradable, water-soluble graft copolymers having builder, anti-filming, dispersibility, and threshold crystallization-inhibiting properties, comprising (a) an acid-functional monomer and, optionally, (b) another water-soluble monoethylenically unsaturated monomer copolymerizable with (a), grafted to a biodegradable substrate comprising a polyalkylene oxide and / or a polyalkoxylated material. However, U.S. Patent No. 5,318,719 requires that each side chain of the graft polymer must contain a large amount of an acid-functional monomer, such as acrylic acid or methacrylic acid. Such types of acid monomers are not useful in the context of the present invention.

[0006] U.S. Patent Application Publication No. 2019 / 0390142 relates to fabric care compositions comprising a graft copolymer that may be composed of (a) a polyalkylene oxide, such as polyethylene oxide (PEG), (b) N-vinylpyrrolidone (VP), and (c) a vinyl ester, such as vinyl acetate. However, U.S. Patent Application Publication No. 2019 / 0390142 does not disclose a backbone, nor any biodegradability, as is currently required, and all examples disclose only polyethylene oxide as the backbone.

[0007] WO 2020 / 005476 discloses a fabric care composition comprising a graft copolymer and a so-called processing aid, the graft copolymer comprising a polyalkylene oxide, preferably polyethylene oxide, as a backbone based on ethylene oxide, propylene oxide, or butylene oxide, and N-vinylpyrrolidone and vinyl esters as grafted side chains on the backbone, with a specific ratio of the backbone and both monomers, however, only polyethylene oxide as the backbone is explicitly disclosed.

[0008] WO 2020 / 264077 discloses cleaning compositions containing a combination of enzymes and polymers, such compositions being suitable for removing stains from soiled materials.

[0009] This publication discloses so-called "suspension graft copolymers" selected from the group consisting of poly(vinyl acetate)-g-poly(ethylene glycol), poly(vinylpyrrolidone)-poly(vinyl acetate)-g-poly(ethylene glycol), and combinations thereof. However, this backbone is not required by the present invention.

[0010] WO 0018375 discloses a pharmaceutical composition comprising a graft polymer obtained by polymerization of at least one vinyl ester of an aliphatic C1-C24 carboxylic acid in the presence of a polyether, the vinyl ester preferably being vinyl acetate. In the most preferred version, the graft polymer is prepared by grafting vinyl acetate onto PEG with a Mw of 6000 g / mol, followed by hydrolysis of the vinyl acetate to alcohol (which may resemble the polymer obtained from the hypothetical monomer "vinyl alcohol"). The main application is the formation of coatings and films on solid pharmaceutical dosage forms such as tablets.

[0011] WO 0018375 discloses polyethers having a number-average molecular weight of less than 500,000 g / mol, preferably 300-100,000 g / mol, particularly preferably 500-20,000 g / mol, and very particularly preferably 800-15,000 g / mol, as the polymer backbone. Furthermore, it is stated that it is advantageous to use ethylene oxide homopolymers or copolymers having an ethylene oxide content of 40-99% by weight, and therefore the content of ethylene oxide units in the ethylene oxide polymer is preferably 40-100 mol%. Suitable comonomers for these copolymers are stated to be propylene oxide, butylene oxide, and / or isobutylene oxide. Suitable examples are copolymers of ethylene oxide and propylene oxide, copolymers of ethylene oxide and butylene oxide, and copolymers of ethylene oxide, propylene oxide, and at least one butylene oxide. It is stated that the ethylene oxide content in the copolymer is preferably 40 to 99 mol %, the propylene oxide content is 1 to 60 mol %, and the butylene oxide content in the copolymer is 1 to 30 mol %. It is stated that not only linear homo- or copolymers but also branched homo- or copolymers can be used as graft bases for grafting.

[0012] However, WO 0018375 only exemplifies PEG 6000 and 9000, "polyethylene glycol / polypropylene glycol block copolymer" (average molecular weight "about 8000"), and "polyglycerol" (average molecular weight "2200") (all g / mol). Five examples use only vinyl acetate, and only one example uses vinyl acetate and methyl methacrylate as monomers. No other monomers are exemplified. All examples use hydrolysis of polymerized vinyl acetate monomer as a final step.

[0013] Thus, polymers containing unhydrolyzed vinyl acetate as claimed in the present invention are not prepared or characterized in WO 0018375.

[0014] Also, specific graft polymers made from polyalkylene oxide polymers other than PEG as the polymer backbone are not disclosed or claimed in WO 0018375.

[0015] The present disclosure therefore focuses on a different composition comprising only PEG grafted with vinyl acetate and then hydrolyzed to vinyl alcohol for use as a film-forming polymer in pharmaceutical applications.

[0016] Also, WO 0018375 does not disclose the use of polymers as disclosed herein for detergent and cleaning applications or fabric care applications, and no such applications or uses are mentioned in the present disclosure. [Prior art documents] [Patent documents]

[0018] It is an object of the present invention to provide detergent compositions comprising a detersive surfactant and novel grafted polymers. Furthermore, these novel grafted polymers should have beneficial properties with respect to biodegradability and / or their cleaning behavior when used in compositions, such as cleaning compositions.

[0019] The object is to provide a detergent composition comprising a detersive surfactant and a graft polymer, the graft polymer having (A) 20 to 95% of the polymer backbone as a graft base, the polymer backbone is obtainable by polymerization of ethylene oxide; A polymer backbone having a molecular weight Mn in the range of 500 to 5000 g / mol; (B) grafted onto the polymer backbone, 5 to 80% of polymer side chains (B), which are obtainable by polymerization of at least one vinyl ester monomer (B1) and optionally at least one other monomer (B2), and if present, the weight ratio of monomer (B2) to monomer (B1) is less than 0.5. (All percentages are weight percent based on the total weight of the grafted polymer), as achieved by the detergent composition. DETAILED DESCRIPTION OF THE INVENTION

[0020] The grafted polymers according to the present invention can be used in detergent compositions, such as cleaning compositions and / or fabric and home care products. They provide at least the same, and preferably even improved, anti-redeposition and cleaning performance in such compositions or products, e.g., in terms of soil redeposition and stain removal, compared to corresponding polymers or grafted polymers according to the prior art. In addition, the grafted polymers according to the present invention, when used in such compositions or products, e.g., cleaning compositions and / or fabric and home care products, provide improved biodegradability.

[0021] The graft polymers with improved biodegradability according to the present invention can be advantageously used in laundry and cleaning compositions, where they support, inter alia, the removal of hydrophobic soils from textiles or hard surfaces by surfactants, thus improving the washing and cleaning performance of the formulations.Furthermore, they also provide better dispersion of the removed soils in the laundry or cleaning liquor, preventing their redeposition on the surface of the washed or cleaned materials.

[0022] As used herein, the articles "a" and "an," when used in a claim, are understood to mean one or more of what is claimed or described. As used herein, the terms "include(s)" and "including" are meant to be open-ended.

[0023] The compositions of the present disclosure can "comprise" (i.e., contain other ingredients), "consist essentially of" (contain primarily or almost only the recited ingredients, with only very small amounts of other ingredients, primarily as mere impurities), or "consist of" (i.e., contain only the recited ingredients, and may additionally contain only impurities, preferably ingredients, unavoidable in the technical circumstances) the ingredients of the present disclosure.

[0024] Similarly, the terms "substantially free of" or "substantially free from" or "containing / comprising essentially no" may be used herein to mean that the indicated material is in minimal amounts and has not been intentionally added to the composition to form part of the composition, or preferably is not present at analytically detectable levels. It means that the indicated material includes compositions in which the indicated material is present only as an impurity in one of the other intentionally included materials. The indicated material may be present, if present at all, at a level of less than 1%, or even less than 0.1%, or even less than 0.01%, or even 0% by weight of the composition.

[0025] As used herein, the term "about" encompasses the exact number "X," as referred to, for example, as "about X%," as well as small variations of X, including deviations from X of minus 5 to plus 5% (X is set to 100% in this calculation), preferably minus 2 to plus 2%, more preferably minus 1 to plus 1%, even more preferably minus 0.5 to plus 0.5% and smaller variations. Of course, if a given value X is itself already "100%" (such as for purity), then the term "about" can clearly refer to that deviation less than "100," and thus refers only to that deviation.

[0026] The phrase "fabric care composition" is intended to include compositions and formulations designed to treat fabrics. Such compositions include, but are not limited to, laundry cleaning compositions and detergents, fabric softening compositions, fabric enhancing compositions, fabric deodorizing compositions, laundry prewash detergents, laundry pretreatments, laundry additives, spray products, dry cleaning agents or compositions, laundry rinse additives, cleaning additives, post-rinse fabric treatments, ironing aids, unit dose formulations, delayed delivery formulations, detergents contained on or in porous substrates or nonwoven sheets, and other suitable forms that may be apparent to those skilled in the art in light of the teachings herein and the teachings detailed herein below when describing compositions. Such compositions may be used as laundry pretreatments, laundry post-treatments, or added during the rinse or wash cycle of a laundry operation, as further detailed herein below when describing the uses and applications of the graft polymers of the present invention and compositions comprising such graft polymers.

[0027] Unless otherwise noted, all ingredient or composition concentrations are in terms of the active portion of that ingredient or composition and are exclusive of impurities, e.g., residual solvents or by-products, that may be present in commercial sources of such ingredient or composition.

[0028] All temperatures herein are in degrees Celsius (°C) unless otherwise indicated. All measurements herein are made at 20°C and atmospheric pressure unless otherwise noted. In all embodiments of the present disclosure, all percentages are by weight of the total composition unless otherwise noted. All ratios are by weight unless otherwise noted.

(All percentages are by weight based on the total weight of the grafted polymer).

[0030] The ratio of the polymer backbone (A) to the polymer side chains (B) in the graft polymer exemplified in the present invention is not limited to a specific value, and in principle, any ratio known to those skilled in the art can be used. However, good results are obtained when the ratios detailed above are used.

[0031] The polymer backbone (A) itself, as well as methods for preparing such copolymer backbones, are known to those skilled in the art, typically the polymerization of ethylene oxide using known means.

[0032] Thus, suitable polymer backbones (A) for use within the scope of the present invention can be readily obtained by standard alkoxylation polymerization processes using ethylene oxide.

[0033] In an alternative embodiment, the present invention also encompasses a graft polymer, the graft polymer comprising: (A) a polymer backbone as a graft base, the polymer backbone being obtainable by polymerization of ethylene oxide; (B) polymeric side chains grafted onto the polymer backbone, said polymeric side chains (B) being obtainable by polymerization of at least one vinyl ester monomer (B1) and optionally at least one other monomer (B2), if present, the weight ratio of monomer (B2) to monomer (B1) being less than 0.5, preferably less than 0.4, more preferably less than 0.3, even more preferably less than 0.2 and most preferably less than 0.1, Here, the product formula P = [molecular weight of polymer backbone Mn (g / mol)] × [percentage of amount of polymer side chain (B) based on total polymer weight (polymer weight is set to "1" and the percentage of amount of (B) as a fraction of it)] is in the range of 50 to 1500, preferably 1200 or less, more preferably 1000 or less, even more preferably 800 or less, and most preferably 600 or less, for example 400 or less, or even 300 or less, and (B) preferably at least 100, more preferably at least 120, polymeric side chains.

[0034] The graft polymers according to the present invention preferably have low polydispersity.

[0035] The graft polymers of the present invention and / or those detailed above have a polydispersity M of less than 5, preferably less than 3.5, more preferably less than 3, and most preferably in the range of 1.0 to 2.5. w / M n It is preferred to have (M w = weight average molecular weight and M n = number average molecular weight, polydispersity has no units [ g / mol / g / mol ]). M w and / or M nThe respective values ​​of can be determined as described in the experimental section below.

[0036] With respect to the graft polymers of the previous embodiments and / or the graft polymers detailed above, it is further preferred that monomer (B2) is not used in the polymerization to obtain side chain (B).

[0037] The polymer backbone (A) contained in the graft polymer according to the present invention and / or the polymer backbone (A) detailed above may be capped or uncapped (uncapped) at each end group of the backbone. Consequently, within the scope of the present invention, the copolymer backbone (A) can be optionally capped at one or both end groups, preferably the copolymer backbone (A) is not capped at both end groups. Capping can be carried out by adding C1 to C 25 This is done by alkyl groups, preferably C1 to C4 groups.

[0038] With regard to the polymer side chains (B) contained in the graft polymer according to the invention, it is preferred that the polymer side chains (B) are obtained by radical polymerization of at least one vinyl ester monomer (B1).

[0039] As the vinyl ester monomer (B1), at least one of vinyl acetate, vinyl propionate and vinyl laurate is selected. In addition to the at least one vinyl ester monomer (B1) mentioned, further vinyl ester monomers (B1) known to those skilled in the art may be used, such as vinyl valerate, vinyl pivalate, vinyl neodecanoate, vinyl decanoate and / or vinyl benzoate.

[0040] However, in a preferred embodiment, the graft polymer of the present invention and / or the graft polymer detailed above comprises polymer side chains (B) which are obtained or can be obtained by radical polymerization of at least one vinyl ester monomer (B1) and optionally at least one other monomer (B2) in the presence of the polymer backbone (A), wherein at least 10% by weight of the total amount of vinyl ester monomers (B1) are selected from vinyl acetate, vinyl propionate and vinyl laurate, more preferably selected from vinyl acetate and vinyl laurate, most preferably vinyl acetate, and the remaining amount of vinyl ester may be any other known vinyl ester, preferably at least 60% by weight, more preferably at least 70% by weight, even more preferably at least 80% by weight, even more preferably at least 90% by weight of vinyl acetate, most preferably essentially only vinyl acetate (i.e. about 100% by weight or even 100% by weight) is used as vinyl ester (weight percentage is based on the total weight of the vinyl ester monomers B1 used), and preferably essentially no other monomers (B2) are used.

[0041] In an even more preferred embodiment, the graft polymer of the present invention and / or the graft polymer detailed above comprises: (A) 20 to 95%, preferably 30 to 90%, more preferably 40 to 85%, and most preferably 50 to 80% of the polymer backbone as a graft base, the polymer backbone is obtainable by polymerization of ethylene oxide; a polymer backbone having a molecular weight Mn in the range of 500 to 5000 g / mol, preferably 3500 g / mol or less, more preferably 3000 g / mol or less, even more preferably 2500 g / mol or less, and most preferably 2000 g / mol or less, for example 1800 g / mol or less; (B) grafted to the polymer backbone, 5 to 80%, preferably 10 to 70%, more preferably 15 to 60%, most preferably 20 to 50% of polymer side chains (B), which polymer side chains (B) are obtainable by polymerization of at least one vinyl ester monomer (B1) and optionally at least one other monomer (B2), and if present, the weight ratio of monomer (B2) to monomer (B1) is less than 0.5, preferably less than 0.4, more preferably less than 0.3, even more preferably less than 0.2, most preferably less than 0.1. (All percentages are by weight based on the total weight of the grafted polymer), at least 10 weight percent of the total amount of the at least one vinyl ester monomer (B1) is selected from vinyl acetate, vinyl propionate, and vinyl laurate, more preferably selected from vinyl acetate and vinyl laurate, most preferably vinyl acetate, and the remaining amount of vinyl ester may be any other known vinyl ester, preferably at least 60 weight percent, more preferably at least 70 weight percent, even more preferably at least 80 weight percent, even more preferably at least 90 weight percent vinyl acetate, most preferably essentially only vinyl acetate (i.e., about 100 weight percent or even 100 weight%) is used as vinyl ester (weight percent is based on the total weight of the vinyl ester monomers B1 used), More preferably, essentially no other monomers (B2) are used.

[0042] In an alternative more preferred embodiment (relative to the previous embodiment), the graft polymer of the present invention and / or the graft polymer detailed above comprises: (A) a polymer backbone (A) as a graft base, a polymer backbone (A), the polymer backbone being obtainable by polymerization of ethylene oxide; (B) polymeric side chains grafted onto the polymer backbone, said polymeric side chains (B) being obtainable by polymerization of at least one vinyl ester monomer (B1) and optionally at least one other monomer (B2), if present, the weight ratio of monomer (B2) to monomer (B1) being less than 0.5, preferably less than 0.4, more preferably less than 0.3, even more preferably less than 0.2 and most preferably less than 0.1, wherein the product formula P=[molecular weight of polymer backbone Mn (g / mol)]×[percentage of amount of polymer side chain (B) based on total polymer weight (polymer weight set to "1" and percentage of amount of (B) as a fraction thereof)] is in the range of 50 to 1500, preferably 1200 or less, more preferably 1000 or less, even more preferably 800 or less, most preferably 600 or less, for example 400 or less, or even 300 or less, and is preferably at least 100, more preferably at least 120; at least 10 weight percent of the total amount of the at least one vinyl ester monomer (B1) is selected from vinyl acetate, vinyl propionate, and vinyl laurate, more preferably selected from vinyl acetate and vinyl laurate, most preferably vinyl acetate, and the remaining amount of vinyl ester may be any other known vinyl ester, preferably at least 60 weight percent, more preferably at least 70 weight percent, even more preferably at least 80 weight percent, even more preferably at least 90 weight percent vinyl acetate, most preferably essentially only vinyl acetate (i.e., about 100 weight percent or even 100 weight%) is used as vinyl ester (weight percent is based on the total weight of the vinyl ester monomers B1 used), More preferably, essentially no other monomers (B2) are used.

[0043] The graft polymers of the present invention may contain a certain amount of non-grafted polymers ("non-grafted side chains") made from vinyl esters, such as polyvinyl acetate when only vinyl acetate is used, and / or homopolymers and copolymers of vinyl esters with other monomers when additional monomers are used. The amount of such non-grafted vinyl ester homopolymers and vinyl ester copolymers may be high or low depending on the reaction conditions, but is preferably reduced, and thus preferably low. This reduction preferably results in an increase in the amount of grafted side chains. Such reduction can be achieved by suitable reaction conditions, such as the dosage and relative amounts of vinyl ester and radical initiator, and also in relation to the amount of backbone present. This is generally known to those skilled in the art.

[0044] The graft polymers of the present invention can be characterized by their degree of grafting (the number of grafting sites of polymer side chains (B) on the polymer backbone (A)). The degree of grafting can be high or low, depending on the reaction conditions. Preferably, the degree of grafting is low to medium, more preferably low. "Low" in this embodiment means that statistically there are less than 2 grafting sites per 50 alkylene oxide units.

[0045] This adjustment of the degree of grafting and the amount of non-grafted polymer can be used to optimize performance in a particular area of ​​interest, such as a particular (e.g., detergent) formulation, application area, or desired cleaning performance.

[0046] In another (non-preferred) embodiment of the present invention, the polymeric side chains (B) of the graft polymer according to the present invention are completely or (more preferably) at least partially hydrolyzed after the graft polymer itself has been obtained, which means that the complete or at least partial hydrolysis of the polymeric side chains (B) of the graft polymer is carried out after the polymerization process of the polymeric side chains (B) has been completed.

[0047] This complete or at least partial hydrolysis of the polymer side chain (B) of the graft polymer according to the present invention converts each side chain unit derived from at least one vinyl ester monomer (B1) from its respective ester functionality in the polymer side chain (B) to an alcohol functionality. It should be noted that the corresponding vinyl alcohol is not suitable for use as a monomer in the polymerization process of the polymer side chain (B) due to its stability. To obtain the alcohol functionality (hydroxy substituent) in the polymer side chain (B) of the graft polymer according to the present invention, the alcohol functionality is typically introduced by hydrolyzing the ester functionality of the side chain.

[0048] From a theoretical point of view, each ester functional group of the polymer side chain (B) can be replaced by an alcohol functional group (hydroxy group). In such a case, the polymer side chain is completely hydrolyzed ("saponified").

[0049] Hydrolysis can be carried out by any method known to those skilled in the art, for example, hydrolysis can be induced by the addition of a suitable base such as sodium hydroxide or potassium hydroxide.

[0050] However, in this embodiment of the invention, it is preferred that the hydrolysis of the polymer side chains (B) is carried out only partially, for example to an extent of up to 20% by weight, up to 40% by weight, or up to 60% by weight (relative to the total weight of the polymer side chains). Even more preferably, in this embodiment, the polymer side chains (B) can be hydrolyzed after polymerization completely or partially, preferably to an extent of up to 50% relative to the amount of the at least one vinyl ester monomer (B1) used in the polymerization.

[0051] However, in the most preferred embodiment of the present invention, the polymer side chains (B) are not hydrolyzed after polymerization.

[0052] In the graft polymers of the present invention and / or the graft polymers described above, it is preferred that no other monomers than those defined above in connection with the at least one vinyl ester monomer (B1) and any additional monomers (B2) present are used in the respective polymerization process to obtain the polymer side chain (B). However, if any additional polymer monomers other than those according to (B1) and optionally (B2) are present, such monomers (other than B1 and B2) are present in an amount of less than 1% of the total amount of monomers used to obtain the polymer side chain (B). Preferably, the amount of such additional monomers is less than 0.5% by weight, even more preferably less than 0.01% by weight, and most preferably, no additional monomers other than the monomers (B1) and optionally (B2) are present at all.

[0053] In a more preferred embodiment thereof, the weight ratio of monomer (B2) to monomer (B1) is less than 0.5, preferably less than 0.4, more preferably less than 0.3, even more preferably less than 0.2, and most preferably less than 0.1, and even more preferably, monomer (B2) is also present in an amount of less than 1% of the total amount of monomers used to obtain the polymer side chains (B). Even more preferably, the amount of monomer (B2) is less than 0.5% by weight, even more preferably less than 0.01% by weight, and most preferably, there is essentially no monomer (B2) present other than monomer (B1).

[0054] Monomer (B2) can in principle be any monomer which is polymerizable with vinyl ester monomer (B1).

[0055] It is particularly preferred in the present invention that no monomers containing acid functional groups are used, in particular the monomers used to obtain the polymer side chains (B) of the graft polymers according to the invention do not comprise any acid functional monomers such as, for example, acrylic acid, methacrylic acid, maleic acid, itaconic acid, crotonic acid, vinylacetic acid or acryloxy-propionic acid.

[0056] The polymer of the present invention has at least one, and preferably two or more of the following properties so that it can be used without problems in the various application fields targeted by the present invention. a) A particular level of biodegradability, such biodegradability of the grafted polymer being at least 30%, preferably at least 35%, even more preferably at least 40%, such as at least 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80% or 85% within 28 days when tested according to OECD 301F (see experimental section for method of measurement). b) A certain degree of water solubility of the polymer, so as to enable it to be used in the aqueous environments typically present in the fields of application generally targeted by the present invention. Preferably, the polymers of the present invention should exhibit moderate to good, more preferably very good, solubility in the environments of aqueous formulations, such as those typically used in various types of formulations, e.g., in the fields of dishwashing, automatic dishwashing, hard surface cleaning, fabric cleaning, fabric care, cosmetic formulations, etc. c) The viscosity of the polymer solution should be such that it can be handled during and after production and presented to the user, e.g., as a "pure" (and typically liquid) product, dissolved in a solvent, typically water and organic solvent, aqueous solution containing only water or only organic solvent, at a reasonably high solids concentration of polymer, the viscosity of such polymer or polymer solution being in a range that allows typical technological process steps, e.g., pouring, pumping, dosing, etc. Thus, the viscosity is preferably in the range of up to about less than 4000 mPas, more preferably at a polymer concentration (based on the total solids of the polymer in the solution, defined by the weight percentage of dry polymer within the total weight of the polymer solution) of preferably at least 10 wt.%, more preferably at least 20 wt.%, even more preferably at least 40 wt.%, most preferably at least 50 wt.%, e.g., at least 60 wt.%, 70 wt.%, 80 wt.% or even 90 wt.%. Preferably, the viscosity should be in the range of at most 3500 mPas, even more preferably at most 3000 mPas, for example at most 4500 mPas, 3750 mPas, 3250 mPas, 2750 mPas, or even 2600 mPas, for example 2500 mPas, 2000 mPas, 1750 mPas, 1500 mPas, 1250 mPas, 1000 mPas, 750 mPas, 500 mPas, 250 mPas, 200 mPas, 150 mPas, or 100 mPas. The viscosity can be measured at 25 ° C or at a higher temperature, for example at 50 ° C or even 60 ° C. This allows for suitable handling of the polymer solution on a commercial scale. Of course, depending on the amount of solvent added, the viscosity can be adjusted as desired, since an increase in the amount of solvent reduces the viscosity, and vice versa. It will also be apparent that the measured viscosity depends on the temperature at which it is measured; for example, the viscosity of a given polymer at a given solids content, e.g., 80 wt. %, will be higher when measured at a lower temperature and lower when measured at a higher temperature. In a preferred embodiment, the solids content of the as-prepared polymer, without the addition of additional solvent, is 70-99 wt. %, more preferably 75-85 wt. %.In a more preferred embodiment, no additional solvent is added and the as-prepared polymer has a solids content of 70 to 99 wt. %, more preferably 75 to 95 wt. %, and a viscosity, measured at 60° C., of less than 3000 mPas, more preferably less than 3250 mPas, or even less than 2750 mPas, 2600 mPas, 2500 mPas, 2000 mPas, 1750 mPas, 1500 mPas, 1250 mPas, 1000 mPas, 750 mPas, 500 mPas, or even less than 250 mPas. Viscosity can be determined as generally known for such polymers, preferably as described in the experimental section below.

[0057] To achieve these requirements, the following guidance can be given on how to achieve such properties in the polymers of the present invention.

[0058] Biodegradability is generally increased by at least one of the following conditions: a lower molecular weight of the polymer backbone (A) compared to the high molecular weight, · A lower weight percentage of polymer side chains (monomer B) grafted to the backbone compared to the high weight percentage.

[0059] As a further criterion, it is of course necessary to evaluate the individual performance of specific polymers, and therefore to rank each individual formulation in specific application fields.Due to the wide utility of the polymers of the present invention, it is not possible to provide an exhaustive overview, but this specification and examples provide guidance on how to prepare and select useful polymers with desired properties and how to adjust properties to desired needs.One such criterion for home care and especially for fabric care is of course washing performance, for example, subjecting specific materials that exhibit specific stains to a defined washing procedure.

[0060] The examples provide some guidance for applications to clean fabrics, i.e., the general area of ​​fabric care.

[0061] Depending on the particular need for a polymer exhibiting defined degrees of biodegradability, water solubility, and viscosity (i.e., handling characteristics), the general and specific teachings herein will guide methods for obtaining such a polymer, although they are not intended to be limited to the specific examples provided.

[0063] It should be noted that the grafting process by which a polymer backbone, such as polymer backbone (A), is grafted with polymer side chains is known per se to those skilled in the art, and any process known to those skilled in the art in this regard can be used in the present invention.

[0064] In the process of the invention, it is preferred that the polymeric side chains (B) are obtained by radical polymerization.

[0065] Such radical polymerizations are also known to those skilled in the art. Those skilled in the art also know that the process of the present invention can be carried out in the presence of a radical-forming initiator (C) and / or at least one solvent (D).

[0070] The term "average polymerization temperature" is intended here to mean that the process is substantially isothermal, but due to the exothermic nature of the reaction there may be temperature fluctuations which are preferably maintained within a range of + / - 10°C, more preferably within a range of + / - 5°C.

[0071] According to the present invention, the (radical-forming) initiator (C) at the average polymerization temperature should have a decomposition half-life of 40 to 500 minutes, preferably 50 to 400 minutes, more preferably 60 to 300 minutes.

[0072] According to the invention, the initiator (C) and the grafting monomers (B1) and / or (B2) are advantageously added in such a way that a low and substantially constant concentration of undecomposed initiator and grafting monomers (B1) and / or (B2) is present in the reaction mixture. The proportion of undecomposed initiator in the reaction mixture as a whole is preferably not more than 15% by weight, in particular not more than 10% by weight, based on the total amount of initiator metered during the monomer addition.

[0083] Solvent (D) is advantageously also used to formulate the graft polymer of the present invention for use (e.g., in laundry and cleaning compositions) and may therefore remain in the polymerization product.

[0084] Preferred examples of these solvents are polyethylene glycols having 2 to 15 ethylene glycol units, polypropylene glycols having 2 to 6 propylene glycol units, and in particular alkoxylation products of C6-C8 alcohols (alkylene glycol monoalkyl ethers and polyalkylene glycol monoalkyl ethers).

[0085] Particularly preferred herein are highly branched C-C 16 Alkoxylation products of alcohols, which allow the formulation of polymer mixtures that are free-flowing at 40-70°C and have very low polymer contents at relatively low viscosities. Branching can be present in the alkyl chain of the alcohol and / or in the polyalkoxylate moiety (copolymerization of at least one propylene oxide, butylene oxide, or isobutylene oxide unit).

[0087] According to the invention, the polymerization is carried out in such a way that an excess of polymer (polymer backbone (A) and formed graft polymer (B)) is always present in the reactor. The ratio of the amount of polymer to non-grafted monomer and initiator is generally greater than or equal to 10:1, preferably greater than or equal to 15:1, more preferably greater than or equal to 20:1.

[0088] The polymerization process according to the invention can in principle be carried out in various reactor types.

[0091] In a further particularly preferred low-solvent process variant, the procedure is as described above, except that solvent (D) is metered in during polymerization to limit the viscosity of the reaction mixture. It is also possible to start the metered addition of solvent only at a later time with advanced polymerization, or to add it partially.

[0092] The polymerization can be carried out under normal pressure or at low or high pressure. If the boiling point of the monomers (B1) or (B2) or the optional diluent (D) used is exceeded at the selected pressure, the polymerization can be carried out with reflux cooling.

Specific embodiments of the amphiphilic alkoxylated grease cleaning polymer of the present invention comprise a core structure and a plurality of alkoxylate groups attached to the core structure. These may comprise, for example, an alkoxylated polyalkyleneimine having an inner polyethylene oxide block and an outer polypropylene oxide block.

[0335] Alkoxylated polyamines can be used for grease and particulate removal. Such compounds include, but are not limited to, ethoxylated polyethyleneimine and its sulfated derivatives. Polypropoxylated derivatives can also be included. A wide variety of amines and polyalkyleneimines can be alkoxylated to various degrees. A useful example is a 600 g / mole polyethyleneimine core ethoxylated to 20 EO groups per NH, available from BASF.

[0336] The compositions may comprise a hydrophilic backbone comprising monomers such as, for example, unsaturated C1-C6 carboxylic acids, ethers, alcohols, aldehydes, ketones, esters, sugar units including polyglucans and other polysaccharides, alkoxy units, maleic anhydride, saturated polyalcohols such as glycerol, and mixtures thereof, and one or more C4-C6 carboxylic acids. 25 Random graft polymers containing hydrophobic side chains, such as alkyl groups, polypropylene, polybutylene, vinyl esters of saturated C1-C6 monocarboxylic acids, C1-C6 alkyl esters of acrylic or methacrylic acid, and mixtures thereof, are also suitable. Specific examples of such graft polymers are based on polyalkylene oxides and vinyl esters, particularly vinyl acetate. These polymers are typically prepared by polymerizing vinyl esters in the presence of polyalkylene oxides, with initiators such as dibenzoyl peroxide, dilauroyl peroxide, or diacetyl peroxide.

[0337] The composition may contain blocks of ethylene oxide and propylene oxide. Examples of such block polymers include ethylene oxide-propylene oxide-ethylene oxide (EO / PO / EO) triblock copolymers, which contain a first EO block, a second EO block, and a PO block, with the first EO block and the second EO block connected to the PO block.

The block polymer may also contain an additional butylene oxide (BO) block.

[0338] Carboxylate Polymers—The compositions of the present invention may also include one or more carboxylate polymers, such as maleate / acrylate random copolymers or polyacrylate homopolymers. Suitable carboxylate polymers are polyacrylate homopolymers having a molecular weight of 4,000 Da to 9,000 Da or 6,000 Da to 9,000 Da. Another suitable carboxylate polymer is a copolymer of acrylic acid and maleic acid having a molecular weight of 50,000 Da to 120,000 Da or 60,000 Da to 80,000 Da.

[0339] Suitable carboxylate polymers may also contain ether and sulfonate moieties.

[0340] Suitable carboxylate polymers may be alkoxylated polycarboxylates. Chemically, these materials comprise polyacrylates with one ethoxy side chain for every 7-8 acrylate units. The side chains have the formula -(CH2CH2O) m (CH2) nCH3, where m is 2-3 and n is 6-12. The side chains are ester-linked to the polyacrylate "backbone" to provide a "comb" polymer type structure. Molecular weights can vary but may range from about 2000 to about 50,000.

[0341] Soil Release Polymer: The compositions described herein may comprise from about 0.01% to about 10.0%, typically from about 0.1% to about 5%, and in some embodiments, from about 0.2% to about 3.0%, by weight of the composition, of a soil release polymer (also known as a polymeric soil release agent or "SRA").

[0342] Soil release polymers typically have a hydrophilic segment for hydrophilizing the surface of hydrophobic fibers such as polyester and nylon, and a hydrophobic segment that deposits on the hydrophobic fibers and remains attached there until the completion of the washing and rinsing cycle, thereby serving as an anchor for the hydrophilic segment. This can make the soil that is lifted after treatment with the soil release agent more easily washable in the subsequent washing procedure. It is also believed that promoting soil release helps improve or maintain the wicking properties of fabrics.

[0343] The structure and charge distribution of the soil release polymer may be tailored for application to different types of fibers or fabrics and for formulation in different detergent or detergent additive products. The soil release polymer may be linear, branched, or star-shaped.

[0344] The soil release polymer may also comprise various charged (e.g., anionic or cationic) and / or uncharged (e.g., nonionic) monomer units. Typically, when the SRP is used in combination with a cationic fabric conditioning active, such as a quaternary ammonium ester compound, a nonionic SRP may be particularly preferred to avoid potentially negative interactions between the SRP and the cationic active.

[0345] The soil release polymer may include end-capping moieties that are particularly effective in controlling the molecular weight of the polymer or altering the physical or surface active properties of the polymer.

[0447] polymer biodegradable Polymer biodegradation in wastewater was tested in triplicate using the OECD 301F manometric respirometry method. 30 mg / mL of test substance was inoculated into wastewater collected from the Mannheim Wastewater Treatment Plant and incubated in sealed flasks at 25°C for 28 days. Oxygen consumption during this period was measured as the change in pressure inside the flask using an OxiTop C (WTW). The evolved CO2 was absorbed using a NaOH solution. The amount of oxygen consumed by the microbial community during the biodegradation of the test substance, after correction using a blank, was expressed as % of ThOD (theoretical oxygen demand).

[0448] The biodegradation data for the inventive and comparative polymers at 28 days in the OECD 301F test are summarized in Table 5. It is clear that the inventive grafted polymers exhibit much higher biodegradability than the comparative polymers.

[0450] Method for evaluating the whiteness effect of polymers Whiteness maintenance, also known as whiteness retention, is the ability of a detergent to prevent white items from losing their whiteness when washed in the presence of soil. White clothing can appear dirty / dull over time as soil is removed from soiled clothing and suspended in the wash water, and these soils can then be redeposited on the clothing, causing the clothing to lose its whiteness each time it is washed.

[0451] The whiteness benefit of the polymers of the present disclosure is evaluated using an automated tergotometer with 10 pots for laundry formulation testing.

[0452] To simulate consumer soiling levels (a mixture of body soil, food, grime, etc.), SBL2004 test soil strips supplied by WFK Testgewebe GmbH are used. On average, 8 g of soil is loaded per SBL2004 strip. The SBL2004 test soil strips are cut into 5 x 5 cm squares for use in the test.

[0453] For some conditions, 0.02 g of carbon black supplied by Alfa Aesar was added. The carbon black was mixed with 5 ml of water and placed in an ultrasonic bath for 15 minutes before addition.

[0454] The white fabric swatches in Table 6 below, purchased from WFK Testgewebe GmbH, are used as whiteness tracers.

[0455] [Table 15]

[0456] Additional ballast (background fabric swatches) are also used to simulate fabric loads and provide mechanical energy during the actual washing process. The ballast loads consist of 5x5cm swatches of cotton and polycotton knits.

[0457] Four wash cycles are required to complete the test. Cycle 1: The desired amount of detergent is completely dissolved by mixing with 1 L of water (defined hardness) in each tergotometer port. 60 grams of fabrics (four types, measured in quadruplicate) containing whiteness tracer, twenty-one 5x5 cm SBL2004 cloths, and ballast are washed and rinsed in the tergotometer pot under defined conditions.

[0458] For testing of the water-soluble unit dose composition, the wash concentration is 2000 ppm. An additional 47 ppm of PVOH film is also added to the tergotometer pot. The wash temperature is 30°C and the water hardness is 20 gpg.

[0459] Cycle 2: After the process of Cycle 1, the whiteness tracer and ballast of each pot are then washed and rinsed again with a new set of SBL2004 (5 x 5 cm, 21 pieces). All other conditions remain the same as in Cycle 1.

[0460] Cycle 3: After the process of Cycle 1, the whiteness tracer and ballast of each pot are then washed and rinsed again with a new set of SBL2004 (5 x 5 cm, 21 pieces). All other conditions remain the same as in Cycle 1.

[0461] Cycle 4: Then, after the process of Cycle 1, the whiteness tracer and ballast of each port are washed and rinsed again with a new set of SBL2004 (5 x 5 cm, 21 pieces). All other conditions remain the same as in Cycle 1.

[0462] For some test conditions, 0.02 g of carbon black supplied by Alfa Aesar is added in addition to the 21 SBLs in each wash cycle described above.

[0463] After cycle 4, all brightness tracers and ballast are tumble dried to dryness at 60-65°C, and then the WI (CIE) of the dried tracers is measured using a Konica Minolta CM-3610D spectrophotometer.

[0464] When carbon black is used in some test conditions, the brightness tracer is dried in an air flow cabinet.

[0465] Methods for evaluating the cleaning effectiveness of polymers The cleaning effectiveness of the polymers is evaluated using a Tergotometer. Some examples of test stains suitable for this test are as follows: Standard glass, manufactured by Equest Standard Black Toad Clay, manufactured by Equest ASTM dust sebum, CFT Highly sensitive sebum-sensitive polycotton fabric, made from CFT Burnt butter on knitted cotton, made by Equest Dyed bacon on knitted cotton, made by Equest

[0466] The stains are analyzed for L, a, and b values ​​using a commercially available image analysis system.

[0467] The polymers of the present invention are typically formulated into a final product along with other ingredients for testing. Cleaning solutions are prepared by diluting the test product with water (of a specified hardness) to a specified cleaning concentration.

[0468] For testing of water-soluble unit dose compositions, an additional 47 ppm of PVOH film is also added to the tergotometer pot. The wash temperature is 30° C. and the water hardness is 8 gpg.

[0469] The fabrics washed in each tergotometer pot included two of each test stain (two internal replicas), thirteen swatches of 5 x 5 cm WfK SBL 2004 stain sheets, and additional knitted cotton ballast to bring the total fabric weight up to 60 g.

[0470] Once all the fabrics were added to the tergotometer pot containing the wash solution, the wash solution was stirred for 40 minutes. The wash solution was then drained, and the fabrics were subjected to one or two 5-minute rinse cycles before being drained and spun dry. The washed stains were dried in an airflow cabinet and then analyzed for L, a, and b values ​​using a commercially available image analysis system.

[0471] Repeat this procedure further to obtain a total of 3–4 external replicas.

[0472] The Stain Removal Index (SRI) is calculated from the L, a, and b values ​​using the formula shown below: The higher the SRI, the better the stain removal. SRI=100 * ((ΔE b -ΔE a ) / ΔE b ) ΔE b =√((L c -L b ) 2 +(a c -a b ) 2 +(b c -b b ) 2 ) ΔE a =√((L c -L a ) 2 +(a c -a a ) 2+(b c -b a ) 2 ) Subscript "b" indicates data for stains before washing Subscript "a" indicates data for stains after washing Subscript "c" indicates data for unstained fabrics

[0473] Polymer Brightness and Cleaning Performance in Liquid Detergents The following water-soluble unit dose detergent compositions E and F are prepared by conventional means known to those skilled in the art by mixing the listed ingredients (Table 7).

[0474] The whiteness maintenance of the polymers of the present invention is evaluated according to the method for evaluating the whiteness performance of a polymer by directly comparing the whiteness performance of Reference Composition E and Test Composition F. The ΔWI(CIE) of Composition F versus Composition E is reported in Table 8 as an indicator of the effectiveness of the polymer whiteness performance. The ΔSRI of Composition F versus Reference Composition E is reported in Table 9 as an indicator of the polymer cleaning performance.
