[0002] As detergent products have evolved, consumers' needs regarding cleaning have been sufficiently met. However, in the field of laundry, there are still some unmet consumer needs. In particular, unmet needs include additional benefits for fabrics after washing, such as a pleasant fragrance, whitening, disinfection, malodor prevention, softening, and insect repellency. To achieve the above benefits, it is known that many beneficial agents including fragrances, optical brighteners, dyes, insect repellents, silicones, waxes, vitamins, fabric softeners, enzymes, and antibacterial agents can be added to laundry products.

The graft copolymer can be present at a level of about 0.01% to about 0.75%, preferably about 0.03% to about 0.65%, more preferably about 0.05% to about 0.50%, most preferably about 0.10% to about 0.29% by weight of the composition, for example, 0.10%, 0.15%, 0.17%, 0.20%, 0.21%, 0.22%, 0.23%, 0.24%, 0.25%, 0.26%, 0.27%, 0.28%, 0.29%, 0.3%, 0.35%, 0.4%, 0.45%, 0.50%, 0.55%, 0.60%, 0.65%, 0.70%, 0.75%, or any range therebetween.

[0034] The graft copolymer contains (a) a polyalkylene oxide having a number average molecular weight of 1000 to 20,000 daltons, based on ethylene oxide, propylene oxide, butylene oxide, or a mixture thereof, (b) N-vinylpyrrolidone, and (c) a vinyl ester derived from a saturated monocarboxylic acid containing 1 to 6 carbon atoms, and the weight ratio of (a):(b) is 1:0.1 to 1:2, preferably 1:0.1 to 1:1, more preferably 1:0.3 to 1:1, and the amount of (a) is greater than the amount of (c) on a weight basis.

[0035] (a):(c) The weight ratio is 1.0:0.1 to 1.0:0.99 or 1.0:0.3 to 1.0:0.9. (b):(c) The weight ratio can be about 1.0:0.1 to about 1.0:5.0, or up to about 1.0:4.0.

[0036] Based on weight, the amount of (a) is greater than the amount of (c). The polymer may contain at least 50% by weight, preferably at least 60% by weight, more preferably at least 75% by weight of (a) polyalkylene oxide.

[0037] The graft copolymer has a number average molecular weight of (a) 1000 to 20000 Da, or up to 15000 Da, or up to 12000 Da, or up to 10000 Da, and is grafted with a polyalkylene oxide based on ethylene oxide, propylene oxide, or butylene oxide, preferably ethylene oxide, and (b) N-vinylpyrrolidone and further (c) a vinyl ester derived from a saturated monocarboxylic acid containing 1 to 6 carbon atoms, preferably vinyl acetate or a derivative thereof, and / or can be obtained thereby.

[0038] Suitable polyalkylene oxides can be based on homopolymers or copolymers, with homopolymers being preferred. The polyalkylene oxide can be a homopolymer of ethylene oxide or based on an ethylene oxide copolymer having an ethylene oxide content of 40 to 99 mol%. Suitable comonomers for such copolymers can include propylene oxide, n-butylene oxide, and / or isobutylene oxide. Suitable copolymers can include copolymers of ethylene oxide and propylene oxide, copolymers of ethylene oxide and butylene oxide, and / or copolymers of ethylene oxide, propylene oxide, and at least one butylene oxide. The copolymer can include an ethylene oxide content of 40 to 99 mol%, a propylene oxide content of 1.0 to 60 mol%, and a butylene oxide content of 0 to 30 mol%. The graft base can be linear (straight-chain) or branched-chain, for example, a branched-chain homopolymer and / or a branched-chain copolymer.

[0039] The branched-chain copolymer can be prepared by adding ethylene oxide, which may or may not contain propylene oxide and / or butylene oxide, to a polyhydric low molecular weight alcohol, such as trimethylolpropane, pentose, or hexose.

[0040] The alkylene oxide units may be randomly distributed in the polymer or present internally as blocks.

[0041] The polyalkylene oxide of component (a) may be the corresponding polyalkylene glycol in free form (i.e., having OH end groups), or one or both end groups may be protected. Suitable end groups can be, for example, C1-C25-alkyl groups, phenyl groups, and C1-C14-alkylphenyl groups. The end group can be a C1-alkyl (e.g., methyl) group. Suitable materials based on grafts include polyethylene glycols such as PEG300, PEG1000, PEG2000, PEG4000, PEG6000, PEG8000, PEG10000, PEG12000, and / or PEG20000, and / or monomethoxypolyethylene glycols such as MPEG2000, MPEG4000, MPEG6000, MPEG8000, and MEG10000 commercially available from BASF under the trade name PLURIOL, and / or block copolymers made from ethylene oxide-propylene oxide-ethylene oxide (EO-PO-EO) or propylene oxide-ethylene oxide-propylene oxide (PO-EO-PO) such as PE6100, PE6800, or PE3100 commercially available from BASF under the trade name PLURONIC.

[0042] The graft copolymers of the present disclosure can be characterized by a relatively low degree of branching (i.e., degree of grafting). In the graft copolymers of the present disclosure, the average number of graft sites can be 1.0 or less, or 0.8 or less, or 0.6 or less, or 0.5 or less, or 0.4 or less per 50 alkylene oxide groups, such as ethylene oxide groups. The graft copolymer can, on average, contain at least 0.05 or at least 0.1 graft sites per 50 alkylene oxide groups, such as ethylene oxide groups, based on the resulting reaction mixture. The degree of branching can be determined, for example, 13 using 13C NMR spectroscopy from the integral values of the signals of the graft sites and the -CH 2 - groups of the polyalkylene oxide.

[0043] The number of graft sites can be adjusted by manipulating the temperature and / or feed rate of the monomer. For example, the polymerization may be carried out in such a way that the excess component (a) and the formed graft copolymer are always present in the reactor. For example, the quantitative molar ratio of component (a) to the polymer and the monomer not grafted to the polymer (and the initiator if present) is usually 10:1 or more, or up to 15:1, or up to about 20:1.

[0044] The polyalkylene oxide is grafted with N-vinylpyrrolidone as the monomer of component (b). Without wishing to be bound by theory, it is believed that the presence of N-vinylpyrrolidone ("vinylpyrrolidone, VP") monomer in the graft copolymer according to the present disclosure provides water solubility and good film-forming properties compared to other similar polymers that do not contain the N-vinylpyrrolidone monomer. The repeating unit of vinylpyrrolidone has amphiphilicity due to a polar amide group that can form a dipole and a non-polar portion with a methylene group that makes the skeleton and ring hydrophobic.

[0045] The polyalkylene oxide is grafted with a vinyl ester as the monomer of component (c). The vinyl ester can be derived from a saturated monocarboxylic acid containing 1 to 6 carbon atoms, or 1 to 3 carbon atoms, or 1 to 2 carbon atoms, or 1 carbon atom. Suitable vinyl esters can be selected from the group consisting of vinyl formate, vinyl acetate, vinyl propionate, vinyl butyrate, vinyl valerate, isovaleric acid vinyl ester, vinyl caproate, or mixtures thereof. Preferred monomers of component (c) include those selected from the group consisting of vinyl acetate, vinyl propionate, or mixtures thereof, preferably vinyl acetate.

[0046] Conventionally, the molecular weight has been represented by the "K value" obtained from relative viscosity measurements. The graft copolymer can have a K value of 5.0 to 200, optionally 5.0 to 50, measured according to H. Fikentscher in a 2% by weight strength solution in dimethylformamide at 25°C.

[0047] The graft copolymers of the present disclosure can be characterized by a relatively narrow molar mass distribution. For example, the graft copolymer can have a polydispersity M of 3.0 or less, or 2.5 or less, or 2.3 or less w / M n and can be characterized by. The polydispersity of the graft copolymer can be 1.5 to 2.2. The polydispersity can be determined by gel permeation chromatography using an organic solvent such as hexafluoroisopropanol (HFIP) with multi-angle laser light scattering detection.

[0048] The average molecular weight Mw of the preferred graft polymer can be 3000 to 100,000 Da, preferably 6000 to 45,000 Da, more preferably 8000 to 30,000 Da.

[0049] The graft copolymer can be prepared by grafting a suitable polyalkylene oxide of component (a) with a monomer of component (b) in the presence of a free radical initiator and / or by the action of high energy radiation (which may include the action of high energy electron beams). This can be done, for example, by dissolving the polyalkylene oxide in at least one monomer of group (b), adding a polymerization initiator, and completely polymerizing the mixture. Also, the graft polymerization can be carried out semi-continuously by first introducing a portion, for example 10%, of the mixture of the polyalkylene oxide to be polymerized, at least one monomer of group (b) and / or (c), and the initiator, heating to the polymerization temperature, and after the polymerization starts, adding the remainder of the mixture to be polymerized at a rate commensurate with the polymerization rate. The graft copolymer can also be obtained by introducing the polyalkylene oxide of group (a) into the reactor, heating to the polymerization temperature, and adding all, little by little, or without interruption, optionally without interruption, at least one monomer of group (b) and / or (c) and the polymerization initiator, and polymerizing.

[0050] In the preparation of the graft copolymer, the order in which monomers (b) and (c) are grafted onto component (a) is not important and / or can be freely selected. For example, first N-vinylpyrrolidone can be grafted onto component (a), and then monomer (c) or a mixture of monomers of group (c) can be grafted. Also, first the monomers of group (c) can be grafted onto the graft base (a), and then N-vinylpyrrolidone can be grafted. It is possible to graft a mixture of monomers (b) and (c) onto the graft base (a) in one step. The graft copolymer can be prepared by providing the graft base (a) and then grafting first N-vinylpyrrolidone and then vinyl acetate onto the graft base.

[0051] Any suitable polymerization initiator can be used, and examples of such polymerization initiators include diacetyl peroxide, dibenzoyl peroxide, succinyl peroxide, di-tert-butyl peroxide, tert-butyl perbenzoate, tert-butyl perpivalate, tert-butyl permaleate, cumene hydroperoxide, diisopropyl peroxydicarbonate, bis(o-toluoyl) peroxide, didecanoyl peroxide, dioctanoyl peroxide, dilauroyl peroxide, tert-butyl perisobutyrate, tert-butyl peracetate, di-tert-amyl peroxide, tert-butyl peracetate, di-tert-amyl peroxide, tert-butyl hydroperoxide, mixtures thereof, redox initiators, and / or organic peroxides such as azo starters. The choice of initiator may be related to the choice of polymerization temperature.

[0052] The graft polymerization can be carried out at about 50 °C to about 200 °C, or about 70 °C to about 140 °C. The graft polymerization can typically be carried out under atmospheric pressure, but can also be carried out under reduced pressure or superatmospheric pressure.

[0053] Graft polymerization can be carried out in a solvent. Suitable solvents include monohydric alcohols such as ethanol, propanol, and / or butanol, polyhydric alcohols such as ethylene glycol and / or propylene glycol, alkylene glycol ethers such as ethylene glycol monomethyl and -ethyl ethers and / or propylene glycol monomethyl and -ethyl ethers, polyalkylene glycols such as di- or tri-ethylene glycol and / or di- or tri-propylene glycol, polyalkylene glycol monoethers such as poly(C2-C3-alkylene) glycol mono(C1-C16-alkyl) ethers having 3 to 20 alkylene glycol units, carboxylic acid esters such as ethyl acetate and ethyl propionate, aliphatic ketones such as acetone and / or cyclohexanone, cyclic ethers such as tetrahydrofuran and / or dioxane, or mixtures thereof, and may contain alginate lyase selected therefrom.

[0054] Also, graft polymerization may be carried out in water as a solvent. In such a case, the first step may be to introduce a solution that is somewhat soluble in water according to the amount of the monomer of the added component (b). In order to transfer the water-insoluble product that may form during polymerization into the solution, for example, an organic solvent such as a monohydric alcohol having 1 to 3 carbon atoms, acetone, and / or dimethylformamide can be added. In the graft polymerization process in water, it is also possible to transfer the water-insoluble graft copolymer into a fine dispersion by adding a normal emulsifier or protective colloid such as polyvinyl alcohol. The emulsifier used can be an ionic or non-ionic surfactant having an HLB value of 3.0 to 13. The HLB value is measured according to the method described in the paper by W.C. Griffin in J.Soc.Cosmet.Chem.5(1954),249.

[0055] The amount of surfactant used in the graft polymerization process can be 0.1 to 5.0% by weight of the graft copolymer. When water is used as the solvent, a solution or dispersion of the graft copolymer can be obtained. When preparing a solution of the graft copolymer in an organic solvent or a mixture of an organic solvent and water, the amount of the organic solvent or solvent mixture used per 100 parts by weight of the graft copolymer can be 5 to 200 parts by weight, optionally 10 to 100 parts by weight.

[0056] After the graft polymerization, optionally, the graft copolymer may be subjected to partial hydrolysis. In the graft copolymer, 1.0 mol% to 60 mol%, preferably 20 mol% to 60 mol%, more preferably 30 mol% to 50 mol% of the grafted monomer of component (c) is hydrolyzed. For example, when a graft copolymer prepared using vinyl acetate or vinyl propionate as component (c) is hydrolyzed, a graft copolymer containing vinyl alcohol units is obtained. The hydrolysis can be carried out, for example, by adding a base such as an aqueous sodium hydroxide solution or an aqueous potassium hydroxide solution, or by adding an acid and heating the mixture as necessary.

[0057] Beneficial agent The detergent composition may contain one or more beneficial agents (plural possible). It is selected from the group consisting of fragrances, insect repellents, silicones, waxes, lubricants, vitamins, fabric softeners, antibacterial agents, skin healing agents, and mixtures thereof.

The DTI polymer may be present at a level of from about 0.001 wt% to about 1 wt%, preferably from about 0.005 wt% to about 0.5 wt%, more preferably from about 0.008 wt% to about 0.2 wt%, most preferably from about 0.01 wt% to about 0.1 wt% of the DTI polymer in the composition, for example, 0.01 wt%, 0.015 wt%, 0.02 wt%, 0.025 wt%, 0.03 wt%, 0.035 wt%, 0.04 wt%, 0.05 wt%, 0.06 wt%, 0.07 wt%, 0.08 wt%, 0.1 wt% or any range therebetween.

[0062] Suitable migration inhibitors are selected from the group consisting of polyvinylpyrrolidone polymers, polyamine N-oxide polymers, copolymers of N-vinylpyrrolidone and N-vinylimidazole, polyvinyl oxazolidone, polyvinylimidazole, and mixtures thereof. Other suitable DTIs are the triazines described in International Publication No. WO 2012 / 095354, the polymeric benzoxazines described in International Publication No. WO 2010 / 130624, the polyvinyltetrazole described in German Patent Application Publication No. DE 10 2009 001 144 A1, the porous polyamide particles described in International Publication No. WO 2009 / 127587, and the insoluble polymer particles described in International Publication No. WO 2009 / 124908. Other suitable DTIs are those described in International Publication No. WO 2012 / 004134 or are polymers selected from the group consisting of (a) amphiphilic alkoxylated polyamines, amphiphilic graft copolymers, zwitterionic soil suspending polymers, manganese phthalocyanine, peroxidase, and mixtures thereof.

[0063] Suitable classes of DTIs include, but are not limited to, polyvinylpyrrolidone polymers, polyamine N-oxide polymers, copolymers of N-vinylpyrrolidone and N-vinylimidazole, polyvinyl oxazolidone, and polyvinylimidazole or mixtures thereof. More specifically, preferred polyamine N-oxide polymers for use herein contain units having the following structural formula: R-AX-P, where P is a polymerizable unit to which an N-O group can be attached, or an N-O group can form part of a polymerizable unit, or an N-O group can be attached to both units, A is one of the following structures: -NC(O)-, -C(O)O-, -S-, -O-, -N=, x is 0 or 1, and R is an aliphatic group, an ethoxylated aliphatic group, an aromatic group, a heterocyclic group, or an alicyclic group or any combination thereof to which the nitrogen of the N-O group can be attached or the N-O group is part of these groups. Preferred polyamine N-oxides are those in which R is a heterocyclic group such as pyridine, pyrrole, imidazole, pyrrolidine, piperidine, and derivatives thereof.

[0064] The N-O group can be represented by the following general structure,

[0065] [Chemical formula] wherein R1, R2, and R3 are an aliphatic group, an aromatic group, a heterocyclic group, or an alicyclic group or a combination thereof, x, y, and z are 0 or 1, and the nitrogen of the N-O group is bonded to any of the aforementioned groups or can form part of any of the aforementioned groups. The amine oxide unit of the polyamine N-oxide has a pKa < 10, preferably pKa < 7, more preferably pKa < 6.

[0066] Any polymer backbone can be used as long as the resulting amine oxide polymer is water-soluble and has migration inhibition properties. Examples of suitable polymer backbones are polyvinyl, polyalkylene, polyester, polyether, polyamide, polyimide, polyacrylate, and mixtures thereof. These polymers include random or block copolymers in which one monomer type is an amine N-oxide and the other monomer type is an N-oxide. The amine N-oxide polymer typically has a ratio of amine to amine N-oxide of 10:1 to 1:1,000,000. However, the number of amine oxide groups present in the polyamine oxide polymer can be varied by appropriate copolymerization or by an appropriate degree of N-oxidation. The polyamine oxide can be obtained at substantially any degree of polymerization.

[0067] Typically, the average molecular weight is in the range of 500 to 1,000,000, more preferably 1,000 to 500,000, and most preferably 5,000 to 100,000. This preferred class of materials can be referred to as "PVNO". The most preferred polyamine N-oxide useful in the detergent compositions of the present invention is poly(4-vinylpyridine-N-oxide) having an average molecular weight of about 50,000 and an amine to amine N-oxide ratio of about 1:4.

[0068] Copolymers of N-vinylpyrrolidone and N-vinylimidazole polymer (referred to as the class of "PVPVI") are also preferred for use herein. Preferably, the PVPVI has an average molecular weight in the range of about 5,000 to about 1,000,000, more preferably 5,000 to about 200,000, and most preferably about 10,000 to about 20,000. (The number average molecular weight range is determined by light scattering as described in Barth et al., Chemical Analysis Vol 113, "Modem Methods of Polymer Characterization"). The PVPVI copolymer typically has a molar ratio of N-vinylimidazole to N-vinylpyrrolidone of 1:1 to 0.2:1, more preferably 0.8:1 to 0.3:1, and most preferably 0.6:1 to 0.4:1.

[0069] These copolymers can be either linear or branched.

[0070] The compositions of the present invention can also use polyvinylpyrrolidone ("PVP") having an average molecular weight of about 5,000 to about 400,000, preferably about 5,000 to about 200,000, and even more preferably about 5,000 to about 50,000. PVP is known to those skilled in the detergent art. See, for example, EP-A-262,897 and EP-A-256,696, which are incorporated herein by reference. Compositions containing PVP can also contain polyethylene glycol ("PEG") having an average molecular weight of about 500 to about 100,000, preferably about 1,000 to about 10,000. Preferably, the ratio of PEG to PVP on a ppm basis delivered in the cleaning solution is about 2:1 to about 50:1, more preferably about 3:1 to about 10:1.

[0071] Suitable examples include PVP-K15, PVP-K30, ChromaBond S-400, ChromaBond S-403E, and Chromabond S-100 manufactured by Ashland, and Sokalan HP165, Sokalan HP50, Sokalan HP53, Sokalan HP59, Sokalan® HP56K, Sokalan® HP66 manufactured by BASF, and Reilline 4140 manufactured by Vertellus.

[0072] Surfactant system Preferably, the composition may contain 4 wt% to 80 wt%, preferably 6 wt% to 50 wt%, more preferably 10 wt% to 30 wt%, for example, 5 wt%, 10 wt%, 15 wt%, 20 wt%, 25 wt%, 30 wt%, 35 wt%, 40 wt%, 45 wt%, 50 wt%, or any range therebetween of a surfactant system. In particular, the surfactant system may have an anionic surfactant and a nonionic surfactant.

[0073] Suitable anionic surfactant systems for the compositions of the present invention are C 6 ~C 20 linear alkylbenzene sulfonate (LAS), C 6 ~C 20 alkyl sulfate (AS), C 6 ~C 20 alkyl alkoxy sulfate (AAS), C 6 ~C 20 methyl ester sulfonate (MES), C 6 ~C 20 alkyl ether carboxylate (AEC), and any combination thereof. For example, the laundry detergent composition may contain C 6 ~C 20 alkyl alkoxy sulfate (AA x S) [wherein x is from about 1 to 30, preferably from about 1 to 15, more preferably from about 1 to 10, and most preferably x is from about 1 to 3]. The alkyl chain in such AA x S may be either linear or branched, and medium-chain branched AAx S surfactants are particularly preferred. Preferred groups of AAs x As S, C where x is about 1 - 3 12 ~C 14 Alkyl alkoxy sulfates are included.

In yet another embodiment, the detergent composition is administered from an automatic dosing washing machine.

[0088] Test method Test 1: Perfume headspace test A. Fabric treatment in a full - scale programmable machine The programmable machine (Electrolux W565H) was pre - washed in a self - cleaning mode (90 °C water, 1 - hour cycle) each time before washing the fabric.

[0089] Cotton fabric (Heavy Cotton, CW98, made by Daxin Textile Co. (Beijing, China)) (20 cm × 20 cm, 3 test fabrics for each washing machine) was washed with a 65 - g sample (i.e., the detergent composition) using the machines and samples in the following table.

[0090] [Table 1]

[0091] The test fabrics were washed in the following cycle together with 1.7 kg of ballast (cotton - to - fabric ratio 8:2) and half of the soiling ballast sheet (SBL2004 available from WfK Testgewebe GmbH (Buerchen, Germany)).

[0092] [Table 2]

[0093] The post - wash test fabrics were wrapped separately in aluminum foil paper and stored at 4 °C before being subjected to headspace measurement.

[0094] Fabric Treatment with a Tergotometer Before testing the headspace of the fragrance, prepare and treat the fabric according to the procedure described below. The fabric is typically "desized" and / or "stripped" of any manufacturer's finish that may be present, pretreated with a fabric strengthener according to A, dried, cut into fabric samples, and then treated with the detergent composition in a tergotometer.

[0095] B1. Method for Desizing Fabric New fabric is desized by washing in a top-loading washing machine (e.g., Kenmore 80 series) with zero-grain water at 49 °C (120 °F) for 2 cycles. All fabrics are tumble dried for 45 minutes at the cotton / high setting in a Kenmore series dryer after the second cycle.

[0096] B2. Method for Pretreating Fabric. The desized fabric is pretreated by washing in a top-loading washing machine (e.g., Kenmore 80 series) with 6 grains of water per gallon at 32 °C using a detergent and a liquid fabric softener for 3 cycles. At the start of the wash cycle, fill the drum of the washing machine with water, then add the detergent (Tide®, 83 g), and then add 2.5 kg of 100% cotton towels (30.5 cm × 30.5 cm, RN 37000-ITL, obtained from Calderon Textiles, LLC (6131 W 80th St Indianapolis IN)) that have been desized. During the rinse cycle, when the rinse water is filled, add the liquid fabric softener (Downy®, 46 g) to the drum. All fabrics are tumble dried for 45 minutes at the cotton / high setting in a Kenmore series dryer after the second cycle. Each treated fabric is cut into circular test specimens with a diameter of 1.4 cm using an air-inflated press mold (Atom Clicker Press SE20C, available from Manufacturing Suppliers Services, Cincinnati, Ohio).

[0097] B3. Method for Treating Fabric with a Tergotometer Fill the tergotometer to a filling volume of 1 L. For washing, use water at 15 gpg / 30 °C, and for rinsing, use water at 15 gpg / 25 °C (77 °F). Program a stirring sweep angle of 15 degrees, a stirring speed of 300 rpm, a stirring time of 12 minutes, and a rinsing cycle of 10 minutes. After the washing and rinsing steps, remove the water by centrifuging at 1500 rpm for 2 minutes. After filling with 350 g of water, add the detergent composition (1.5 g) to the washing pot and then stir for 60 seconds. Place a pre-conditioned fabric (circle with a diameter of 8 × 1.4 cm) into a glass sample vial (#24694, available from Restek, Bellefonte, Pennsylvania), record the weight (circle with a diameter of 8 × 1.4 cm, approximately 0.63 g ± 0.07 g), and cover the vial (#093640 - 094 - 00, MD, available from Gerstel, Linthicum, Maryland). Once the detergent and all test fabrics have been added to the tergotometer pot, start the timed cycle. After the washing cycle is complete, remove the fabric and dry it at 30 minutes / 62 °C. For each flavor headspace analysis, prepare and analyze 12 replicates according to the method described above.

[0098] Flavor Headspace Measurement The flavor headspace was measured using a GCMS (Agilent Technologies 7800B GC System, Agilent Technologies 5977B MSD, column: Agilent Technologies 122 - 5532UI DB - 5MS UI 30m * 0.250 mm, 0.25 Micro, -60 to 325 / 350 °C, SN: USN754641H, Gerstel MultiPurpose Sampler SPME (Solid Phase Microextraction) fiber assembly 50 / 30um DVB / CAR / PDMS, Stableflex (2 cm) 23Ga, autosampler, Gray - Notched, SUPELCO 57299 - U).

[0099] The washed fabric was cut into pieces with dimensions of 5 cm × 8 cm, then placed in a 20 ml headspace vial and then capped. The capped vial was equilibrated at room temperature (25 °C) for 2 hours and filled into the GCMS for analysis.

[0100] To load the headspace active substances, the SPME fiber extracted the headspace at room temperature for 5 minutes and was then transferred to the GCMS injection port and desorbed at 270 °C for 3 minutes. Next, the desorbed contents were placed into the GCMS for analysis, with no splitting in GC and in scan mode in MS. The GCMS response data was processed and quantified by Agilent MassHunter Quantification software using a quantification method and then analyzed using JMP.

Example

[0101] Synthesis Example 1: Synthesis of graft copolymer A graft polymer with a weight ratio of PVP / PVAc-g-PEG of 20:30:50 and a weight average molecular weight of 16,800 Daltons was prepared as follows.

[0102] First, 720 g of PEG (6000 g / mol) and 60 g of 1,2-propanediol (MPG) were charged into a polymerization vessel equipped with a stirrer and a reflux condenser under a nitrogen atmosphere. The mixture was homogenized at 70 °C.

[0103] Next, 432 g of vinyl acetate (after 2 hours), 288 g of vinyl pyrrolidone in 576 g of MPG (after 5 hours), and 30.2 g of tert-butyl perpivalate in 196.6 g of MPG (after 5.5 hours) were weighed and charged. After the feeds were added completely, the solution was stirred at 70 °C for 1 hour. Then, 3.8 g of tert-butyl perpivalate in 25.0 g of MPG (after 1.5 hours) was weighed and charged, followed by stirring for 0.5 hour.

[0104] Volatile substances were removed by vacuum stripping. Then, 676.8 g of deionized water was added and steam distillation was carried out at 100 °C for 1 hour.

[0105] The temperature of the reaction mixture was lowered to 80 °C, and 160.6 g of an aqueous sodium hydroxide solution (50%, 40 mol% of VAc each) was added at the maximum feed rate. After the sodium hydroxide solution was completely added, the mixture was stirred at 80 °C for 1 hour and then cooled to ambient temperature.

[0106] The obtained graft polymer is characterized in that its K value is 24. The solid content of the final solution is 45%.

[0107] Example 1. Improvement in the effectiveness of a beneficial agent by adding a graft copolymer to a laundry detergent composition Four sample liquid laundry detergent compositions containing the following components were prepared. Sample 1 does not contain a graft polymer. Samples 2 - 4 contain graft copolymers at different levels.

[0108]

Table 3

[0109] According to Test 1 above: Headspace of fragrance (Method B), the tergotometer method was used to treat the fabric, and the content of fragrance in the headspace of the laundry washed by using these samples was measured. Such content indicates the effectiveness of fragrance expression on the fabric after washing.

[0110] The results are shown in Table 2 below. The liquid laundry detergent composition containing the graft copolymer shows higher effectiveness of the fragrance on the fabric after washing as compared to the liquid laundry detergent composition not containing the graft copolymer. Further unexpectedly, Samples 2 and 3 containing the graft copolymer at relatively low levels (0.4% and 0.7%) show surprisingly high effectiveness of the fragrance as compared to Sample 4 containing the graft copolymer at a relatively high level (1.5%). Furthermore, there are several perfume raw materials (PRMs) that are preferentially expressed more with the lowest level of the graft copolymer, and the wet fabric headspace of several preferential perfume raw materials is increased by about 20%.

[0112] Example 2: Improvement in the effectiveness of beneficial agents by adding a graft copolymer to a laundry detergent composition Four sample liquid laundry detergent compositions containing the following components were prepared. Sample 5 does not contain a polymer. Samples 6 and 7 contain the graft copolymer at two different levels. Sample 8 contains another type of polymer (i.e., a PEI polymer).

[0113]

Table 5

[0114] According to Test 1 above: Fragrance Headspace (Method A), the content of fragrance in the headspace of the clothes washed in a washing machine using these samples was measured. Such content indicates the effectiveness of fragrance expression on the fabric after washing.

[0115] The results are shown in the following table, and the liquid laundry detergent composition containing the graft copolymer shows extremely high effectiveness of the fragrance on the fabric after washing as compared with the liquid laundry detergent composition containing no polymer or containing a PEI polymer. Further unexpectedly, Sample 6 containing the graft copolymer at a very low level (0.25%) shows even higher effectiveness of the fragrance as compared with Sample 7 containing the graft copolymer at a relatively high level (0.4%).
