Description

TECHNICAL FIELD

[0001] Full laundry softening additive. BACKGROUND

[0002] Consumers have consistently shown interest in products that can simplify the process they use to launder clothes, help them reduce the time they spend on laundry chores, and help them achieve high levels of cleaning and softness in their family's clothes. Current laundry cleaning and softening requires consumers to dose two products into different compartments of the washing machine, or dose one product into the washing machine and dose one product into the dryer.

[0003] The process of laundering fabrics can be divided into three basic steps: washing, rinsing, and drying. The washing step typically uses water and a detergent composition that includes anionic surfactant, as well as other active agents that are compatible with the anionic surfactant in the unused product form and in the wash liquor formed during the washing step. After washing, the clothes are rinsed one or more times as part of the rinsing step.

[0004] Currently, laundry softening is most commonly and practically achieved during the rinsing step with a liquid softening composition that is separated from the detergent composition, or during the drying step. To apply the liquid softening composition to the clothes in the washing machine, the liquid softening composition is added to the clothes during the rinsing step. The liquid softening composition can be automatically introduced into the rinse from a compartment that keeps the liquid softening composition separate from the wash composition. The compartment can be part of the agitator, if present, or another part of the washing machine that can be opened to dispense the liquid softening composition into the drum. This is commonly referred to as full rinse softening. Full rinse softening requires the consumer to dose the detergent composition and the softening composition into different locations of the washing machine, which is inconvenient.

[0005] Laundry softening can also be achieved during the drying step using a fabric softening sheet. With either of these cleaning and softening methods, cleaning and softening are performed separately.

[0006] Consumers find it inconvenient to have to dispense multiple products into different locations, whether the location is part of the washing machine or the location is distributed between the washing machine and the dryer. What consumers want is the ability to dose the detergent composition and the softening composition into a single location.

[0007] Unfortunately, liquid detergent compositions tend to be incompatible with softening compositions. Liquid detergent compositions contain anionic surfactants to aid in cleaning the laundry. Softening compositions typically contain cationic surfactants to soften the laundry. When combined in a single package, the anionic surfactants and cationic surfactants can mix and form a solid precipitate. When packaged together in a liquid form or packaged together in a wash liquor, this results in stability issues for the combination and reduced cleaning performance compared to detergent compositions without the softening composition. This incompatibility issue is one of the reasons that detergent compositions and fabric softening compositions are dosed and applied separately from one another. Liquid fabric softening compositions packaged separately from detergent compositions can not be preferred by some consumers due to the inconvenience of dosing the compositions into the washing machine, the perceived messiness, and the texture of the product.

[0008] In view of these limitations, there is an ongoing unmet need for a full wash fabric softening composition in a solid form that can be dispensed by the consumer along with a laundry detergent to provide softening throughout the wash during the wash step. SUMMARY

[0009] A composition comprising a plurality of particles, the plurality of particles comprising: from about 25% to about 94% by weight of a water soluble carrier; from about 5% to about 45% by weight of a first hydrophobic conditioning compound having a weight average molecular weight of greater than 1000 Da; and from about 0.5% to about 10% by weight of a cationic polysaccharide; from about 5% to about 50% by weight of a salt; and wherein individual particles of the plurality of particles have a mass of from about 1 mg to about 1 g. DETAILED DESCRIPTION

[0010] The compositions described herein can provide a full wash fabric softening composition that is convenient for the consumer to dose into the washing machine. The full wash fabric softening composition can be provided in the form of a composition comprising a plurality of particles. The particles can be provided in a package separate from the package of the detergent composition. Having the particles of the softening composition in a package separate from the package of the detergent composition can be beneficial because it allows the consumer to select the amount of softening composition independent of the amount of detergent composition used. This can give the consumer the opportunity to customize the amount of softening composition used and thus the degree of softening benefit they achieve, which is a highly valuable consumer benefit.

[0011] Many consumers prefer granular products, especially non-dusting particulates. Consumers can easily dose the granular product directly from the package into the washing machine or into a dosing compartment on the washing machine. Or the consumer can dose from the package into a measuring cup, which optionally provides one or more dosing indicia, and then dose the particulate into a dosing compartment on the washing machine or directly into the drum. For products where a measuring cup is employed, granular products tend to be cleaner than liquid products.

[0012] The plurality of particles of the fabric softening composition can comprise a water-soluble carrier and a first hydrophobic conditioning compound having a weight average molecular weight greater than 1000 Da (Da is an abbreviation for Daltons). Optionally, they can comprise a cationic polysaccharide. The carrier brings the first hydrophobic conditioning compound into the washing machine. The particles dissolve in the wash liquor. The first hydrophobic conditioning compound deposits from the wash liquor onto the fibers of the fabric.

The plurality of particles can comprise from about 25% to about 94%, optionally from about 25% to about 89%, optionally from about 25% to about 81%, optionally from about 30% to about 90%, optionally from about 35% to about 88%, optionally from about 40% to about 88%, optionally from about 45% to about 85%, optionally combinations thereof, and any integer percentage or range of integer percentages within any of the above ranges, by weight of the plurality of particles. The water-soluble carrier serves to bring the fabric care benefit agent into the wash liquor. Upon dissolution of the water-soluble carrier, the first hydrophobic conditioning compound and any additional materials making up the particle are dispersed into the wash liquor.

[0015] Water-soluble means that the material or particle is soluble or dispersible in water and optionally has a water solubility of at least 50%, optionally at least 75%, or even at least 95%, as measured by the method set forth below using a glass filter with a maximum pore size of 20 microns: Add 50 grams ± 0.1 gram of carrier to a pre-weighed 400 mL beaker and add 245 mL ± 1 mL of distilled water. Vigorously stir on a magnetic stirrer set at 600 rpm for 30 minutes. Then, filter the mixture through a porous glass filter with the specified pore size (maximum 20 microns) described above. This step is performed at a temperature of 23 °C ± 1.0 °C and a relative humidity of 50% ± 2%. Dry the moisture from the collected filtrate by any conventional method and determine the weight of the remaining material (the portion that was dissolved or dispersed).

The non-halide salt is characterized by a particle size of less than 600 microns, optionally 50 microns to 600 microns, optionally 50 microns to 420 microns. The average particle size of the non-halide salt can be characterized by passing the salt material through sieves having different mesh sizes.

[0247] The non-halide salt can be chemically different from the water-soluble carrier.

[0248] Nonionic surfactant

[0249] The nonionic surfactant can be selected from alcohol alkoxylate nonionic surfactants, including naturally derived alcohol, synthetically derived alcohol based alcohol alkoxylate nonionic surfactants, and mixtures thereof, depending on the average alkyl carbon chain length and average degree of branching desired. The alcohol alkoxylate nonionic surfactant can be a primary or secondary alcohol alkoxylate nonionic surfactant, optionally a primary alcohol alkoxylate nonionic surfactant. The synthetically derived alcohol alkoxylate nonionic surfactants include Ziegler synthesized alcohol alkoxylates, carbonyl synthesized alcohol alkoxylates, modified carbonyl process synthesized alcohol alkoxylates, Fischer-Tropsch synthesized alcohol alkoxylates, Guebert alcohol alkoxylates, alkyl phenol alcohol alkoxylates, or mixtures thereof. The alkoxylated chain can be a mixed alkoxylated chain comprising ethoxy, propoxy, and / or butoxy units, or can be a pure ethoxylated alkyl chain, optionally a pure ethoxylated alkyl chain.

[0250] Suitable nonionic surfactants can include alkoxylated fatty alcohols. The nonionic surfactant can be selected from ethoxylated alcohols and ethoxylated alkyl phenols of the formula R(OC2H4)OH, wherein R is selected from the group consisting of an aliphatic hydrocarbon group containing from about 8 to about 15 carbon atoms and an alkyl phenyl group in which the alkyl group contains from about 8 to about 12 carbon atoms, and n has an average value of from about 5 to about 15.

[0251] Other non-limiting examples of nonionic surfactants useful herein include: C8-C18 alkyl ethoxylates, such as NEODOL nonionic surfactants from Shell; C6-C12 alkyl phenol alkoxylates, where the alkoxylate units can be ethyleneoxy units, propyleneoxy units, or mixtures thereof; condensates of C12-C18 alcohols and C6-C12 alkyl phenols with ethylene oxide / propylene oxide block polymers, such as PLURONIC from BASF; C14-C22 mid-chain branched alcohols, BA; C14-C22 mid-chain branched alkyl alkoxylates, BAEX, where x is 1 to 30; alkyl polysaccharides; in particular alkyl polyglycosides; polyhydroxy fatty acid amides; and ether capped poly(alkoxylated) alcohol surfactants. Specific examples include C11-C15 EO12 and C11-C15 EO9 TERGITOL nonionic surfactants from Dow, C12-C15 EO7 and C14-C15 EO7 NEODOL nonionic surfactants from Shell, C12-C14 EO7 and C12-C14 EO9 SURFONIC nonionic surfactants from Huntsman. Other suitable nonionic surfactants are condensation products of a Guerbet alcohol with 2 to 18 moles, optionally 2 to 15 moles, optionally 5 to 9 moles of ethylene oxide per mole of alcohol. Suitable nonionic surfactants include those available from BASF under the trade name LUTENSOL. LUTENSOL XP-50 is a Guerbet ethoxylate containing 5 ethoxy groups. LUTENSOL XP-80 and contains 8 ethoxy groups. Other suitable nonionic surfactants for use herein include fatty alcohol polyglycol ethers, alkyl polyglucosides, and fatty acid glucamides, and / or Guerbet alcohol based alkyl polyglycosides.

[0252] The nonionic surfactant can include linear surfactants, branched surfactants, or mixtures thereof, optionally linear nonionic surfactants, branched nonionic surfactants, or mixtures thereof.

[0253] Suitable nonionic surfactants can have an HLB of 8 to 15. Optionally, suitable nonionic surfactants can have a molecular weight of less than 1000 Da.

[0254] Without being bound by theory, it is believed that the inclusion of a nonionic surfactant as described herein can help slow or limit crystallization of the hydrophobic conditioning compound when provided as part of a premix or in the precursor material that forms the particles. Crystallization of the hydrophobic conditioning compound in the premix or in the precursor material that forms the particles can affect the viscosity of the melt that produces the plurality of particles. The viscosity of the melt that produces the particles can affect the formation of the particles. In addition, it is believed that the nonionic surfactant can limit the particle size of the crystallized hydrophobic conditioning compound, which can help reduce fabric staining and improve softness when such particles are used in a wash.

[0255] As part of the method for forming the particles, a premix of the nonionic surfactant and the hydrophobic conditioning compound and optionally additional particle formulation components can be provided. The premix can include the desired weight fraction of the nonionic surfactant and the hydrophobic conditioning compound. The premix can include from about 20% to about 98% by weight of the first hydrophobic conditioning compound and from about 2% to about 80% by weight of the nonionic surfactant. Optionally, the premix can include from about 50% to about 70% by weight of the first hydrophobic conditioning compound and from about 30% to about 50% by weight of the nonionic surfactant. Optionally, additional formulation components can be included in the premix, including but not limited to cationic polysaccharides and optionally salts. The premix of the above ingredients can be heated and mixed at a temperature of from about 65°C to about 85°C. The premix can be added to a melt of the water-soluble carrier to form a precursor material from which the particles are formed. The premix and the melt of the water-soluble carrier can be mixed to form the precursor material, which can then be used to manufacture the particles, as further described herein.

[0256] Granules

[0257] The individual particles that make up the plurality of particles can have an individual mass of from about 1 mg to about 1 g. The smaller the individual particles, the more they tend to dissolve in water more quickly. The individual particles that make up the plurality of particles can have an individual or average particle mass of from about 1 mg to about 1000 mg, alternatively from about 5 mg to about 500 mg, alternatively from about 5 mg to about 200 mg, alternatively from about 10 mg to about 100 mg, alternatively from about 20 mg to about 50 mg, alternatively from about 35 mg to about 45 mg, alternatively about 38 mg. The individual particles that make up the plurality of particles can have a mass standard deviation of less than about 30 mg, alternatively less than about 15 mg, alternatively less than about 5 mg, alternatively about 3 mg. An average particle mass within the above ranges can provide a dispersion time in water that allows the particles to dissolve during a typical wash cycle. Without being bound by theory, it is believed that particles having this mass standard deviation can have a more uniform dispersion time in water compared to particles having a wider mass standard deviation. The smaller the mass standard deviation of the particles, the more uniform the dispersion time. The mass of the individual particles that make up the plurality of particles can be set to provide a desired dispersion time that can be a fraction of the length of a typical wash cycle in a washing machine.

[0258] The plurality of particles can be substantially free of particles having a mass of less than 10 mg. This can be useful to limit the ability of the particles to spread in the air.

[0259] The individual particles can have a volume of from about 0.003 cm3 3 to about 5 cm3 3 , optionally from about 0.003 cm3 3 to about 1 cm3 3 , optionally from about 0.003 cm3 3 to about 0.5 cm3 3 , optionally from about 0.003 cm3 3 to about 0.2 cm3 3 , optionally from about 0.003 cm3 3 to about 0.15 cm3 3 It is believed that smaller particles provide better particle stacking in a container and faster dissolution in a wash.

[0260] The composition can include individual particles that remain on a No. 10 sieve as specified by ASTM International, ASTM E11-13. The composition can include individual particles wherein more than about 50% by weight, optionally more than about 70% by weight, optionally more than about 90% by weight of the individual particles remain on a No. 10 sieve as specified by ASTM International, ASTM E11-13. It can be desirable to provide individual particles of such a size because individual particles that remain on a No. 10 sieve can be easier to handle than smaller individual particles.

[0261] The composition can comprise individual particles that are retained on a No. 6 sieve as specified by ASTM International, ASTM E11-13. The composition can comprise individual particles, wherein more than about 50% by weight, optionally more than about 70% by weight, optionally more than about 90% by weight of the individual particles are retained on a No. 6 sieve as specified by ASTM International, ASTM E11-13. It can be desirable to provide individual particles of such a size because individual particles retained on a No. 6 sieve can be easier to handle than smaller individual particles.

[0262] The composition can comprise individual particles that pass through a sieve having a nominal sieve opening size of 22.6 mm. The composition can comprise individual particles that pass through a sieve having a nominal sieve opening size of 22.6 mm and are retained on a sieve having a nominal sieve opening size of 0.841 mm. Individual particles having a size such that they are retained on a sieve having a nominal sieve opening size of 22.6 mm can tend to have too long a dispersion time for common wash cycles. Individual particles having a size such that they pass through a sieve having a nominal sieve opening size of 0.841 mm can be too small to be conveniently handled. Individual particles having a size within the ranges described above can represent an appropriate balance between dispersion time and ease of handling of the particles.

[0263] Individual particles having the sizes disclosed herein can be large enough such that when poured from a container, measuring cup, or other device into a laundry tub or washing machine, they do not readily become airborne in the air. In addition, such individual particles as disclosed herein are capable of being easily and accurately poured from a container into a measuring cup. Thus, such individual particles can enable a consumer to easily control the amount of first hydrophobic conditioning compound and optional second hydrophobic conditioning compound that he or she delivers into a wash.

[0264] The plurality of particles can be combined together to constitute a dose for dosing into a washing machine or laundry tub. A single dose of the plurality of particles can comprise from about 1 g to about 50 g of particles. A single dose of the plurality of particles can comprise from about 5 g to about 50 g, or from about 10 g to about 45 g, or from about 20 g to about 40 g, or combinations thereof, and any integral gram or integral range of grams within any of the foregoing ranges. The plurality of particles can be comprised of individual particles having different sizes, shapes, and / or masses. The individual particles of a dose can each have a maximum dimension of less than about 15 mm. The individual particles of a dose can have a maximum dimension of less than about 1 cm.

[0265] The plurality of particles can comprise an antioxidant. The antioxidant can help promote the stability of the color and / or odor of the particles over time between production and use. The plurality of particles can comprise about 0.01% to about 1% by weight of an antioxidant, optionally about 0.001% to about 2% by weight of an antioxidant, optionally about 0.01% to about 0.1% by weight of an antioxidant. The antioxidant can be butylated hydroxytoluene.

[0266] The particles can be formed by an intermittent or continuous rotary forming process. Rotary forming processes are described in US5013498A, US5770235A, US20110017130 Al and US10465048B2. The particles can be hemispherical, compressed hemispherical, or the particles have at least one substantially flat or flat surface. The particles can have a flat surface and a curved surface opposite the flat surface. Such particles can have a relatively high surface area to mass ratio compared to spherical particles.

[0267] The particles can be formed by forming a melt of the constituent materials of the particles and forming the particles using a rotary forming process. The particles can be formed on a SANDVIK ROTOFORM 300 having a 750 mm wide 10 m long belt. The cylinders can have 2 mm diameter holes that are arranged in the cross direction at a 10 mm pitch and in the longitudinal direction at a 9.35 mm pitch. The cylinders can be arranged about 3 mm above the belt. The belt speed and the rotational speed of the cylinders 110 can be set to 10 m / min.

[0268] After forming the melt, or for example using an intermittent process or a continuous in-line process, or a combination thereof, the precursor material can be pumped through a plate and frame heat exchanger set to control the outlet temperature to 50°C at a constant rate of 3.1 kg / min, or even 4 kg / min. The pressure in the feed tube downstream of the pump can be about 2 to about 7 bar, and alternatively about 5.5 bar or about 5 bar.

[0269] The utility of a processing melt can depend at least in part on the viscosity of the melt. For any of the compositions described herein, it is desirable that the composition have a viscosity of about 1 Pa-s to about 10 Pa-s at 65°C, about 1 Pa-s to about 5 Pa-s at 65°C, optionally about 1.5 to about 4, optionally about 1 Pa-s to about 3 Pa-s, optionally about 2. Such compositions can be conveniently processed on a rotary forming machine and produce particles having the desired shape.

[0270] By way of non-limiting example, the viscosity can be controlled by adding a diluent to the composition. The plurality of particles and or individual particles can comprise a diluent. The diluent can be selected from the group of dipropylene glycol, a fatty acid, and combinations thereof.

[0271] The plurality of particles can comprise individual particles comprising at least one of the first hydrophobic conditioning compound, the optional second hydrophobic conditioning compound, the cationic polysaccharide, and the salt. The individual particles can comprise one or more of the first hydrophobic conditioning compound, the optional second hydrophobic conditioning compound, the cationic polysaccharide, and the salt. The individual particles can differ from one another in the weight fraction of at least one of the first hydrophobic conditioning compound, the optional second hydrophobic conditioning compound, the cationic polysaccharide, and the salt. The individual particles can differ from one another in the weight fraction of one or more of the first hydrophobic conditioning compound, the optional second hydrophobic conditioning compound, the cationic polysaccharide, and the salt. Providing individual particles that differ from one another in the weight fraction of at least one of the first hydrophobic conditioning compound, the optional second hydrophobic conditioning compound, the cationic polysaccharide, and the salt can simplify the ability of the manufacturer to provide multiple variants of the composition of the plurality of particles.

[0272] Optionally, the individual particles can comprise the first hydrophobic conditioning compound, the optional second hydrophobic conditioning compound, the cationic polysaccharide, and the salt. The individual particles can each be identical in composition to one another. Optionally, the individual particles can comprise the same ingredients, but the weight fraction of the ingredients differs from one another. Such a combination can be useful to provide products that differ from one another in the amount of consumer benefit provided. For example, high active particles and moderate active particles can be blended together to provide a consumer benefit that is intermediate to the consumer benefit provided by the high active particles alone or the moderate active particles alone.

[0273] The manufacturer can form the plurality of particles by blending different weight fractions of the individual particles to achieve the desired level of the first hydrophobic conditioning compound and the optional second hydrophobic conditioning compound. For example, the manufacturer can prepare a first set of individual particles comprising a water-soluble carrier and the first hydrophobic conditioning compound and substantially free or free of the cationic polysaccharide or some weight fraction of the cationic polysaccharide other than the weight fraction of the cationic polysaccharide in the second set of particles. The manufacturer can also prepare a second set of individual particles comprising a water-soluble carrier and the cationic polysaccharide and substantially free or free of the first hydrophobic conditioning compound or some weight fraction of the first hydrophobic conditioning compound other than the weight fraction of the first hydrophobic conditioning compound in the first set of particles.

[0274] The manufacturer can then blend the individual sets of particles of the selected weight fraction to make a plurality of particles having the desired weight fraction of water-soluble carrier, first hydrophobic conditioning compound, optional second hydrophobic conditioning compound, cationic polysaccharide, and salt. The manufacturer can assemble the plurality of particles with the desired weight fraction of first hydrophobic conditioning compound and optional second hydrophobic conditioning compound to provide the composition of the plurality of particles with the desired benefit. The desired weight fraction can be selected based on the desired level of softness, the cost of the composition, the typical wash conditions within a geographic location, the different needs of different market segments, or other factors. This can reduce the number of formulations that the manufacturer must maintain production expertise and control over, reduce the number of formulations that the manufacturer must maintain and specify for certain production runs, and reduce the number of production interruptions to provide compositional variations of the plurality of particles.

[0275] Examples

[0276] Preparation of granules

[0277] The particles were made by providing a 65:35 weight percent blend of PLURIOL E 8000 Prill polyethylene glycol having a weight average molecular weight of 9000 Da and Dow Carbowax polyethylene glycol having a weight average molecular weight of 4000 Da in a MAX 100 SPEEDMIX cup, respectively, and placing the cup material in an oven with a temperature of 80 °C overnight to melt. The one or more hydrophobic conditioning compounds were placed in an oven at 80 °C for 30 minutes before adding them to the polyethylene glycol blend. The MAX 100 SPEEDMIX cup of the polyethylene glycol blend was removed from the oven before starting production of the particles in the morning. The cationic polysaccharide, the one or more hydrophobic conditioning compounds, and the salt, if used, were added to the MAX 100 SPEEDMIX cup containing the melted polyethylene glycol blend. The contents of the MAX 100 SPEEDMIX cup were mixed thoroughly by vortexing with a spatula and immediately placed in a SPEEDMIXER DAC 150 FVC-K (FLAK TEK Inc.) at 3500 revolutions per minute for 60 seconds. The mixture was immediately poured onto a rubber mold held in a 4 °C refrigerator and spread into the indentations in the rubber mold with a spatula. The mixture hardened in the indentations of the rubber mold to form particles. The hardened particles were removed from the rubber mold. The mold shape was a flat half-sphere with a diameter of 5.0 mm and a height of 2.5. The sample particles were stored at 23 °C and 50% relative humidity for 5 days before testing softness performance.

[0278] Method for treating an article of laundry

[0279] To evaluate the softness performance of the particles disclosed herein, the fabric was prepared / processed through a wash sub-cycle according to the following method.

[0280] A. Apparatus and materials

[0281] The fabric was evaluated using a Kenmore FS 600 and / or 80 series washing machine. The washing machine was set to: 20°C / 20°C wash / rinse temperature, 3 grains of hardness per gallon water, normal cycle and small load (46 liters). The fabric bundle consisted of 2.4 kilograms of clean fabric consisting of 50% cotton and 50% polycotton ballast (9 pieces of cotton, 9 pieces of polycotton). The test sample was included in this bundle and consisted of 3-100% cotton (479) and 3-50% / 50% polycotton (7422) fabric ordered from Test Fabrics.

[0282] B. Stripping and desizing

[0283] Prior to treatment with any test product, the fabric bundle was stripped according to the fabric preparation - strip and desizing procedure prior to running the test.

[0284] The fabric preparation - strip and desizing procedure included washing the fabric bundle (2.7-3.6 Kg of fabric consisting of 50% cotton and 50% polycotton ballast) for 5 consecutive wash cycles with only the first 2 cycles with liquid detergent at 140°F (60°C) soft water. The test sample fabric and fabric bundle were stripped / desized using a liquid detergent containing alcohol ethoxy sulfate, linear alkylbenzene sulfonate, C12-C16 alcohol ethoxylate AE9, fatty acids, and other minor ingredients. The wash cycles 3-5 were washed in 140°F (60°C) soft water without detergent. After the fifth wash and rinse cycle, the fabric bundle was transferred to a high setting Kenmore dryer for 50 minutes. The wash conditions were as follows: TL Kenmore 600 and / or 80 series washing machine (or equivalent), set to: 60°C / 60°C wash / rinse temperature, soft water, heavy load cycle, and 22 gallon fill. The dryer timer was set to be in the cotton / high / timed dry setting for 50 minutes.

[0285] C. Test treatments

[0286] Fabric was treated with 82 g of liquid detergent containing no Tide fragrance (no enzymes, no dyes, 1.9% alcohol ethoxy sulfate, 10.1% linear alkylbenzene sulfonate, 3.5% sodium lauryl sulfate, 0.3% amine oxide, and 10.5% nonionic surfactant) and 37 g of sample granules added at a dose of 82 g. The detergent was added below the water surface as the machine filled the drum with water. Once the water stopped flowing and the washer began agitating, 37 g of sample granules were added to the wash liquor. After 5 seconds of agitation, the machine was stopped and a clean bundle of fabric was added. The wash cycle was then resumed. When the wash / rinse cycle was complete, each bundle of wet fabric was transferred to a corresponding dryer. The dryers used were Maytag commercial series (or equivalent) electric dryers with the timer set to the cotton / high heat / timed dry setting for 50 minutes. After the dry cycle was complete, the test fabric was placed in a constant temperature / relative humidity (21 °C, 50% relative humidity) controlled room for 12 to 24 hours before the softness performance was evaluated.

[0287] Secant modulus Instron method

[0288] Hyperbolic Modulus was measured using a tensile and compression tester instrument Instron Model 5565 (Instron Corp., Norwood, Massachusetts, U.S.A.). The instrument was configured according to fabric type by selecting the following settings: mode was tensile extension; waveform shape was triangle; maximum strain was 10% for 479 and 494 100% pure cotton woven and 35% for 7422 50:50 polyester cotton knit; rate was 0.83 mm / sec for 100% pure cotton woven and 2.5 mm / sec for polyester cotton knit; number of cycles was 4; and hold time between cycles was 15 seconds. Fabric samples were prepared and evaluated following the following steps.

[0289] 1. Cut off one full face of stitched edges in the warp direction from each sample with scissors and carefully peel away the fine threads without pressing the fabric until a flat edge is obtained.

[0290]

[0291] 2. Place the fabric press mold which cuts a 1” wide and at least 4” long strip parallel to the flat edge and cut the strip lengthwise in the warp direction.

[0292]

[0293] 3. Cut 3 strips of 100% pure cotton woven or polyester cotton knit test fabric from 3 separate fabric samples per treatment. Each strip was cut to be 1” wide and at least 4” long.

[0294]

[0295] ​​​conditioned in a room at 23 °C (50% RH) for at least 6 hours.

[0296] 4. The top and bottom of the fabric strip are clamped in the 2.54 cm clamps on the tensile tester instrument, set the gap to 2.54 cm, and a small amount of force (0.0.05 N - 0.2 N) is applied to the sample.

[0297] 5. The bottom clamp is released and the sample is re-clamped during the hold cycle, a force of 0.05 N - 0.2 N is loaded on the sample, and the relaxation is eliminated by loading the same force again.

[0298] 6. When the sample has completed 4 hysteresis cycles, the secant modulus is calculated at the maximum strain for each fabric type and averaged over the 9 samples for each treatment. The average secant modulus for the control fabric is subtracted from the average secant modulus for the designated test fabric from each experiment and then reported as delta secant modulus. A positive delta secant modulus indicates that the test fabric has a lower secant modulus than the control fabric. A fabric that is more lubricious has a lower secant modulus which is considered to be softer than the corresponding control fabric. A negative delta secant modulus indicates that the test fabric has a higher secant modulus than the control fabric. A fabric that is less lubricious has a higher secant modulus which is considered to be less soft than the corresponding control fabric.

[0299] Viscosity

[0300] The viscosity of a component of a consumer product composition (e.g., a hydrophobic conditioning compound or a carrier material) is determined as follows.

[0301] For a given component, the reported viscosity is the viscosity value as measured by the following method, which generally represents the infinite-shear viscosity (or infinite-rate viscosity) of the component. Viscosity measurements are made using a TA Discovery HR-2 hybrid rheometer (TA Instruments, New Castle, Delaware, U.S.A.) and the accompanying TRIOS software version 3.0.2.3156. The instrument is equipped with a 40 mm stainless steel parallel plate (TA Instruments, catalog number 511400.901), a Peltier plate (TA Instruments catalog number 533230.901), and a solvent trap cover (TA Instruments, catalog number 511400.901). Calibration is performed according to the manufacturer’s recommendations. A refrigerated circulating water bath set to 25 °C is attached to the Peltier plate. The Peltier plate temperature is set to 65 °C. The temperature is monitored until the instrument reaches the set temperature, and then for an additional 5 minutes to ensure equilibration before loading the sample material onto the Peltier plate.

[0302] To load liquid materials (e.g., hydrophobic conditioning compounds), place the pre-melted sample in an oven set to 70C and use a pipette to transfer 2 ml of the liquid material onto the center surface of the Peltier plate. To load non-liquid materials (e.g., carrier materials), add 2 grams of the non-liquid material onto the center surface of the Peltier plate and allow the sample to fully liquefy. If the loaded sample liquid contains visible air bubbles, wait a period of 10 minutes for the air bubbles to migrate through the sample and break, or a pipette can be used to draw the air bubbles out. If air bubbles remain, remove the sample from the plate, clean the plate with an isopropanol wipe and allow the solvent to evaporate off. Then attempt the sample loading process again and repeat until the sample is successfully loaded without visible air bubbles.

[0303] Lower the parallel plates to several stages of position, with the gap distance initially set to 50 micrometers. With respect to the plates at this gap distance, after waiting 60 seconds, lower the parallel plates further to a position with the gap distance set to 1 millimeter.

[0304] After locking the parallel plates, use a rubber squeegee to remove any excess sample material from the perimeter of the parallel plates. It is important to ensure that the sample is evenly distributed around the edges of the parallel plates and that there is no sample on the sides or top of the plates. If there is sample material on the sides or top of the plates, gently remove this excess material. Carefully apply the solvent trap cover to the parallel plates.

[0305] Use the instrument program and settings (IPS) as follows:

[0306] 1) Conditioning step (pre-conditioning sample) under the "Environmental Control" tab: "Temperature" is 25 °C, "Relay Setpoint" is selected, "Soak Time" is 0.0 s, "Wait for Temperature" is not selected;

[0312] 3) To measure the viscosity of the sample at an additional temperature, the "Conditioning Step" of Step #1 above is programmed as the next step, and the "Temperature" is set to 60C (under "Environmental Control"). All other parameters remain the same.

[0313] 4) The flow peak holding step is repeated for this new temperature exactly as described in Step #2 above.

[0314] 5) Steps #3 and #4 are continued using the following temperatures in the conditioning step: 55°C, 53°C, 52°C, 51°C, 50°C, 49°C, 48°C.

[0315] After the data is collected, the data set is opened in the TRIOS software. The data points are analyzed as follows:

[0316] In the Peak Hold tab of the data, the peak hold -1 is selected (corresponding to the data obtained at 65°C). The average (mean) of the viscosity values (in units of Pa-s) is reported.

[0317] If necessary, this analysis is repeated to obtain the average (mean) of the viscosity values for the additional temperatures being evaluated

[0318] The viscosity value.

[0319] The reported viscosity value for the component being measured is the average (mean) of three independent viscosity measurements (i.e., three replicate sample preparations) and is expressed in units of Pa-s.

[0320] Molecular weight

[0321] Weight average molecular weight (M w ) values are determined on an Agilent 1260 HPLC system equipped with an auto-sampler, column oven, and refractive index detector. The operating system is OpenLAB CDS ChemStation workstation (A.01.03). Data storage and analysis are performed using Cirrus GPC Offline (GPC / SEC software for ChemStation, version 3.4). The chromatographic conditions are given in Table 1. When performing calculations, the results are calibrated using a polystyrene reference sample of known molecular weight. Mw The measured values ​​differed by 5% or less. Molecular weight analysis was performed using chloroform as the mobile phase.

[0327] The granules listed in Table 3 were prepared according to the preparation method provided in this instruction manual to evaluate the effect of salt addition on the beneficial softening effect of the granules on fabrics. Fabrics were treated with the sample granules and tumble-dried according to the method for treating garments provided in the instruction manual. After the washing process, the fabrics were equilibrated overnight in a controlled temperature and humidity chamber (21°C / 50% relative humidity) before evaluation. After equilibration, the secant modulus of the test fabrics was evaluated according to the test method provided in the instruction manual. It is believed that a Δsecant modulus of at least 10 points is required for 100% cotton woven fabrics of 494 and 479, or 0.5 points is required for 742250:50 polyester-cotton knitted fabrics, to allow consumers to notice the beneficial effect of the fabric's softness relative to the control.

[0328] As shown in Table 3, compared with fabrics treated with particles containing only hydrophobic conditioning compounds or a combination of hydrophobic conditioning compounds and 1.75% cationic polysaccharide by weight, fabrics treated with particles containing hydrophobic conditioning compounds or a combination of hydrophobic conditioning compounds, 1.75% cationic polysaccharide by weight and 21.10% magnesium sulfate by weight have a positive Δ secant modulus.

[0337] To evaluate the efficacy of different types of salts to provide fabric softening benefits, the granule samples listed in Tables 4, 5, and 6 were prepared according to the same method specified in Table 3. After evaluation, the sample granules of each salt listed in Tables 4, 5, and 6 were stored at 23°C and 50% relative humidity for 1 month and visually inspected to evaluate if the granules maintained the initial shape after storage. According to the method provided in the instructions for treating a laundry article, the fabric was treated with the sample granules and tumble dried. After the wash process was complete, the fabric was equilibrated in a controlled temperature and humidity chamber (21°C / 50% relative humidity) overnight before evaluation. After the fabric was equilibrated, the secant modulus of the 494 and 479 100% cotton fabrics and the 7422 50:50 polyester cotton knit fabric were evaluated according to the test method provided in the instructions.

[0338] As shown in Tables 4, 5, and 6, the fabric treated with granules containing a combination of a hydrophobic conditioning compound having an average molecular weight greater than 1000 Da, 1.75% by weight cationic polysaccharide, and different levels of non-halide salt had a positive delta secant modulus compared to fabric treated with control granules containing only a combination of a hydrophobic conditioning compound having an average molecular weight greater than 1000 Da and 1.75% by weight cationic polysaccharide. Examples 5 and 6 in Table 4 show that fabric treated with granules containing a halide salt had a neutral or negative delta secant modulus relative to the control. It is believed that the halide salt hydrates upon exposure to environmental conditions, forming a halide salt hydrate that dissolves in its own water of hydration in the granule upon storage, causing the granule to turn into a powder and not provide softness benefits.

[0376] As shown in Table 8, fabrics treated with a particle containing the same hydrophobic conditioning compound, 1.75% by weight cationic polysaccharide, and 21.21% by weight magnesium sulfate salt had a positive delta inverse modulus compared to fabrics treated with a control particle containing only a hydrophobic conditioning compound having an average molecular weight greater than 1,000 Da and 1.75% by weight cationic polysaccharide. Examples 21 and 23 in Table 8 show that fabrics treated with a particle containing a hydrophobic conditioning compound having an average molecular weight less than 1,000 Da had a delta inverse modulus that was near neutral or negative relative to the control. It is believed that the hydrophobic conditioning compound having an average molecular weight less than 1,000 could not be well mixed in the polyethylene glycol melt, resulting in poor dispersion and phase separation of the hydrophobic conditioning compound in the melt, which could impact the particle preparation process, resulting in neutral to negative softness conditioning benefits.
