Description

COMPOSITIONS FOR THE TREATMENT OF FABRICS COMPRISING CAPSULES OF BENEFICIATING AGENT FIELD OF INVENTION The invention relates to fabric treatment compositions comprising biphenyl brightening agent and beautifying agent capsules, and to the use thereof. BACKGROUND OF THE INVENTION Fabric treatment compositions used in the laundry process provide benefits to fabrics through the use of fabric brighteners. One example is the maintenance of a vibrant appearance provided by brighteners. Another example is the pleasant scent provided by perfumes. A problem in the field is that much of the fabric brightener, particularly perfume, is not deposited or rinsed away during fabric treatment. Since perfumes and other fabric brighteners are expensive components, encapsulation can be used to improve the release of the brightener during use. Typically, brightener capsules contain the brightener until the capsule ruptures during use, releasing the brightener.As such, after breaking the capsules of the beneficial agent containing perfume, the release of the perfume provides freshness benefits. It remains a challenge, however, to effectively deposit the benefit agent capsules onto treated fabrics, especially if the capsules are contained in a fabric treatment composition that is diluted in a washing solution during use to treat surfaces such as fabric fibers (e.g., laundry detergents or fabric softeners). Depositing aids have previously been identified to improve the deposition of the benefit agent capsules. However, adding depositing aids to fabric treatment compositions increases costs and complexity at the manufacturing site because an additional ingredient requires additional pumps and storage tanks. Therefore, there remains a need to improve the deposition of benefit agent capsules on fabrics to enhance the supply of benefit agents to provide more durable benefits during and after the use of the fabric treatment composition, while minimizing the cost and complexity of the fabric treatment composition formula. Patent No. WO2016049456 Al relates to capsule aggregates that 7! i Lnn / Lznz / E / Yi contain two or more beneficiation particles, each containing an active material and a polymeric material that immobilizes the active material; one or more binding polymers, each having an anionic chemical group with a negative charge or capable of acquiring a negative charge; and one or more depot polymers, each having a cationic chemical group with a positive charge or capable of acquiring a positive charge. Patent No. WO201701385 relates to beneficiation agent capsules coated with a particular mixture of copolymers. U.S. Patent No. 201701892831 relates to a microcapsule composition containing beneficiation agent capsules coated with a depot protein, e.g., a protein-silanol copolymer, a protein-silane copolymer, a protein-siloxane copolymer, or a cationicly modified protein. BRIEF DESCRIPTION OF THE INVENTION The invention relates to fabric treatment compositions comprising benefit agent capsules, wherein the benefit agent capsules comprise a coating material derived from polyvinyl alcohol and a coating component. The fabric treatment further comprises a surfactant and a biphenyl brightener. The invention also relates to wash water comprising the composition for the treatment of fabrics. The invention also relates to the use of such a composition for the treatment of fabrics to improve the deposition of the beneficial agent capsules. One objective of the invention is to improve the deposition of the beneficial agent capsules.

Composition for the treatment of fabrics The fabric treatment composition according to the present invention comprises benefit agent capsules, wherein the benefit agent capsules comprise a shell material encapsulating a core material, wherein said shell material is derived from polyvinyl alcohol, and a cover component, wherein said cover component is selected from the list consisting of polyamine, melamine 7! i Lnn / Lznz / E / Yi formaldehyde, polyurea, polyurethane, polysaccharide, modified polysaccharide, formaldehyde-crosslinked urea, glutaraldehyde-crosslinked urea, silicon dioxide, sodium silicate, polyester, polyacrylamide, and mixtures thereof; said core material comprises a beneficiation agent. The fabric treatment composition further comprises a biphenyl brightener and preferably at least 1% surfactant. The fabric treatment composition may be a solid or a liquid; preferably the fabric treatment composition is a liquid. Biphenyl brightener. The fabric treatment composition of the present invention comprises a biphenyl brightener having the formula 7! i Lnn / Lznz / E / Yi where M is a suitable cation, preferably M is H+ or Na+, with greater preference M is Na+. It has been surprisingly discovered that the biphenyl brightener according to the present invention provides an improved deposit of the beneficiation agent capsules, wherein the beneficiation agent capsules comprise a shell material encapsulating a core material, and wherein said shell material is derived from polyvinyl alcohol and a coating component. Without any theoretical limitations, it is believed that the deposit is enhanced through the interaction between the polyvinyl alcohol and the biphenyl brightener according to the present invention. Examples of suitable biphenyl brighteners may be supplied under the trade name Tinopal® CBS-X, supplied by BASF; CF-351-UP Granular Brightener, supplied by Cenkey; CBX-X, supplied by Qingshan; Megawhite DT, supplied by Meghmani; Optical Brightener Agent 49 No. 3-E, supplied by Hongda; FL Brightener 49 CI 351, supplied by Alcochem; Keyfluor™ White ML, supplied by Milliken. In preferred fabric treatment compositions, less than 1%, more preferably less than 0.01%, of the total amount of biphenyl brightener, according to the present invention, in the fabric treatment composition is encapsulated in the benefiting agent capsules. The unencapsulated biphenyl brightener provides the treated fabrics with a vivid appearance and improved deposit of the benefiting agent capsule. In preferred compositions for the treatment of fabrics, the total level of biphenyl brightener is 0.01% to 2%, preferably 0.04% to 1.5%, with a higher preference of 0.06% to 1%, with the highest preference of 0.1% to 0.5%, by weight of the composition.

In one aspect of the invention, the level of biphenyl brightener in the wash water comprising the fabric treatment composition is from 0.1 to 50 ppm, preferably from 1 to 30 ppm, more preferably from 2 to 20 ppm, even more preferably from 2 to 10 ppm by weight of the wash water. The biphenyl brightener can be added separately to the fabric treatment composition comprising the other ingredients. Preferred fabric treatment compositions comprise the biphenyl brightener according to the present invention, wherein the biphenyl brightener is premixed before being added to the remaining ingredients of the fabric treatment composition, and wherein the premix comprises the biphenyl brightener, water, and a component selected from a list consisting of organic solvents, nonionic surfactant, and mixtures thereof; preferably wherein the organic solvent is selected from a list consisting of diethylene glycol, monoethanolamine, 1,2-propanediol, and mixtures thereof, most preferably wherein the organic solvent is 1,2-propanediol. The biphenyl brightener premix facilitates the homogeneous distribution of the brightener throughout the fabric treatment composition.Without any theoretical limitations, the applicant believes that the homogeneous distribution of the biphenyl brightener further improves the deposition of the benefit agent capsule on the fabrics.

For each treatment, the washing machine was loaded with 3 kg of fabric, comprising 1500 g of woven cotton fabric and 1100 g of polyester-cotton (50 / 50) fabrics. Six terry cloth tracers (supplied by Maes Textiles), weighing a total of 260 g, were also added for void space analysis. This load was pre-conditioned twice with 79 g of unscented IEC A Base detergent, supplied by WFK Testgewebe GmbH, using the short 95 °C cotton cycle, followed by two additional 95 °C washes without detergent. For the test treatment, the load was washed using a short 30 °C synthetic cycle with 60 g of the fabric treatment composition, which was added at the beginning of the wash cycle using a dosing ball.After washing, the terry cloth tracers are dried on the line and analyzed using the following method to determine the concentration of the void space above the treated fabrics. Method for determining the concentration of empty space above treated fabrics At the end of the wash cycle, the terry cloth tracers are removed from the washing machine and dried on the line overnight. The following day, the dried terry cloth tracers are analyzed for void space using a fast GC / MS (gas chromatography-mass spectrometry) method. 4 x 4 cm aliquots of the terry cloth tracers are transferred to 25 ml void space flasks. The cloth samples are equilibrated for 10 minutes at 75 °C. Void space samples are taken from the cloths using SPME focusing (50 / 30 pm DVB / Carboxene / PDMS) for 5 minutes. The SPME fiber is subsequently thermally desorbed online in the GC. The analytes are analyzed by fast GC / MS in full scan mode. Ion extraction of the specific masses of the perfume raw materials is used to calculate the total HS response and the perfume void space composition above the tested rounds.The results are reported as a void space index where the dry void space of the test treatment is expressed as a ratio versus the reference treatment which has an index of 1. Method for measuring the viscosity of polyvinyl alcohol solution Viscosity is measured using a Brookfield LV series viscometer or equivalent, measured at 4.00% + / - 0.05% solids. a. A solid solution of polyvinyl alcohol at 4.00% + / - 0.05% is prepared. A 500 mL beaker and stirrer are weighed and their weights recorded. 16.00 ± 0.01 grams of a polyvinyl alcohol sample are added to the beaker. Approximately 350–375 mL of [unspecified liquid] is then added. 7! Add deionized water to the beaker and stir the solution. Place the beaker in a hot water bath with the cover plate. Stir at a moderate speed for 45 minutes to 1 hour, or until the polyvinyl alcohol is completely dissolved. Turn off the stirrer. Cool the beaker to approximately 20 °C. 7! i Lnn / Lznz / E / Yi The final weight of the glass is calculated as follows: Final weight = (weight of stirrer and empty beaker) + (% solids as a decimal x 400) Example: Weight of stirrer and empty beaker = 125.0 grams % of polyvinyl alcohol solids (of the sample) = 97.50% or 0.9750 as a decimal Final weight=125.0 + (0.9750 x 400)=515.0 grams A top-loading balance is zeroed, and the beaker containing the polyvinyl alcohol solution with a propeller is placed on it. Deionized water is added to adjust the weight to the final calculated weight of 515.0 grams. The solids content of the sample must be 4.00 + 0.05% to measure viscosity. b. Viscosity measurement The 4% polyvinyl alcohol solution sample is dispensed into the viscometer chamber, the spindle is inserted, and it is connected to the viscometer. The sample adapter (SSA) with chamber is SC4-13RPY, and the Ultralow adapter is used. The spindles are SC4-18 and 00. The sample is allowed to reach equilibrium at 20 °C. The viscometer is started, and the steady-state viscosity value is recorded. Viscosity <13 cP is reported to the nearest 0.01 cP, 13-100 cP to the nearest 0.1 cP; viscosities greater than 100 cP are reported to the nearest 1 cP. Corrections to the determined viscosity are not necessary if the calculated solution solids content is 4.00 ± 0.05%. Otherwise, use the following equation to correct the determined viscosity for deviations in solution solids. Corrected LogeViscosity = (Measured Logviscosity) (percent solids) x (0.2060) + (0.1759) Corrected viscosity = 2.718282 (log of corrected viscosity) Examples The polyacrylate beneficiation agent capsules comprising perfume are prepared as follows: a first oily phase, consisting of 37.5 g of perfume, 0.2 g of tert-butylaminoethyl methacrylate and 0.2 g of beta hydroxyethyl acrylate, is mixed for approximately 1 hour before the addition of 18 g of CN975 (Sartomer, Exter, PA). The solution is left to mix until required later in the process. A second oil phase, consisting of 65 g of perfume oil, 84 g of isopropyl myristate, 1 g of 2,2'-azobis(2-methylbutyronitrile), and 0.8 g of 4,4'-azobis[4-cyanovaleric acid], is added to a lined steel reactor. The reactor is maintained at 35 °C, and the oil solution is mixed at 500 rpm using a 2-inch flat paddle mixer. A nitrogen blanket is applied to the reactor at a rate of 300 cc / min. The solution is heated to 70 °C in 45 minutes and held at 70 °C for 45 minutes before being cooled to 50 °C in 75 minutes. The first oil phase is added at 50 °C, and the combined oils are mixed for a further 10 minutes at 50 °C. An aqueous phase is prepared, containing 85 g of Selvol 540 PVA (Sekisui Specialty Chemicals, Dallas, TX) at 5% solids, 268 g of water, 1.2 g of 4,4'-azobis[4-cyanovaleric acid], 1.1 g of 21.5% NaOH, and mixed until the 4,4'-azobis[4-cyanovaleric acid] is dissolved. Once the temperature of the oil phase is reduced to 50 °C, mixing is stopped and the aqueous phase is added to the blended oils. High shear agitation is applied to produce an emulsion with the desired size characteristics (1900 rpm for 60 minutes). Then, the temperature is increased to 75°C in 30 minutes, maintained at 75°C for 4 hours, heated to 95°C in 30 minutes and maintained at 95°C for 6 hours. Examples 1 to 4 of fabric treatment compositions were prepared as described below. Water, sodium hydroxide, and solvents were mixed in a plastic cup using a paddle mixer. Surfactants, chelating agents, additives, and polymers were added to this mixture during mixing. The final pH was reduced with ethanolamine to a pH (10% dilution) of approximately 8. The mixture is then cooled to room temperature, and during further mixing, dye, enzymes, polymers, preservatives, processing aids, and a structuring agent are added. In Examples 2 and 4, the biphenyl brightener premix was also added, starting with a brightener premix. Brightener premix 49 is supplied by 7! i Lnn / Lznz / E / Yi Calvary Industries, and the brightener 49 is 8.4% active in an aqueous solution of 1,2-propanediol and ethoxylated alcohol. Polish 49 corresponds to the formula 7! i Lnn / Lznz / E / Yi where M corresponds to Na+. The premixes were prepared to allow for homogeneous distribution of the brightener in all compositions.

Since the measurement of the void space 5 records the concentration of perfume raw materials that were originally encapsulated in the benefiting agent capsules, an increase in the concentration of the void space can be related to greater deposition from the benefiting agent capsules. Furthermore, it can be observed that higher levels of biphenyl brightener (Ex. 3-4) showed a further improvement in the void space and, therefore, in the deposition compared to lower levels of biphenyl brightener 10 (Ex. 2). The dimensions and values ​​described herein should not be understood as strictly limited to the exact numerical values ​​stated. Instead, unless otherwise specified, each such dimension shall mean the stated value and a functionally equivalent range encompassing that value. For example, a dimension described as 40 mm refers to approximately 40 mm. NOVELTY OF THE INVENTION 7! i Lnn / Lznz / E / Yi
