Patent Grant
11220657
This application relates to fragranced compositions for fabric treatment that contain a cationic polymer, and methods for the use and manufacture thereof.
When treating and/or laundering fabrics, consumers often want not only to wash, clean or maintain the fabrics to be treated, but also to have additional benefits. For example, consumers prefer that, following washing with laundry detergent and/or fabric softener(s), and drying, the fabrics smell pleasant and feel soft. Consumers can choose detergents and/or fabric softeners having ingredients that provide some softening. However, consumers may desire greater degrees of softening than commercially available detergents and/or fabric softeners may provide.
Accordingly, a need exists for fabric softening that is better than softening provided by currently available detergents and/or fabric softeners
Softening ingredients, and other beneficial ingredients are typically included as an integral component of a washing or cleaning agent. However, the ability to separately meter a solid composition comprising one or more beneficial agents into the washing drum at the start of a washing cycle allows consumers to control the amount of benefit agent provided to the laundry through customized metering. For example, solid compositions comprising melt bodies containing fragrance are already available to consumers. Consumers can add varying amounts of this solid composition to the washing drum to meter the amount of fragrance delivered to laundry. However, these compositions do not provide additional softening to fabrics.
Accordingly, need exists for solid compositions that effectively deliver softness to fabrics in the presence of a detergent during a wash cycle.
The compositions and methods provided in the present disclosure are exemplary and are not intended to limit the scope of the claims.
The present inventors surprisingly found that the compositions of the present disclosure significantly boost the softness of fabrics or textiles compared to the softness of fabrics or textiles that were not treated with the compositions of the present disclosure.
In one aspect, the present disclosure provides a composition for fabric treatment comprising at least one cationic polymer, at least one water-soluble carrier, at least one fragrance, and at least one buffer system.
In one aspect, the cationic polymer is present in the composition for fabric treatment at an amount of from about 0.25% to about 2.5%.
In one aspect, the composition further comprises a silicone.
In another aspect, the composition for fabric treatment further comprises silicone.
In another aspect, the composition for fabric treatment further comprises a rheology modifier.
In another aspect, the composition for fabric treatment further comprises an emulsifying substance.
In another aspect, the composition for fabric treatment further comprises a colorant.
In another aspect, the composition for fabric treatment further comprises a bittering agent.
In another aspect, the composition for fabric treatment further comprises a solvent.
In another aspect, the composition for fabric treatment further comprises water.
In another aspect, the disclosure provides a method of making a solid, particulate composition for fabric treatment, comprising: mixing a water-soluble solid carrier and a buffer system to form a mixture; wherein the solid carrier is an aqueous salt having a water vapor partial pressure at a temperature of from about 30° C. to about 100° C. that corresponds to the water vapor partial pressure of a saturated solution of the salt at the same temperature; adding a cationic polymer and a fragrance into the mixture; mixing the mixture; heating the mixture and obtaining a melt thereby; and cooling and shaping the melt into individual particles comprising melt bodies.
In another aspect, the disclosure provides a method of delivering softening to a textile comprising contacting the textile with a composition for fabric treatment of the present disclosure.
All of the various aspects, aspects, and options disclosed herein can be combined in any and all variants unless otherwise specified. Terms in this application control in the event of a conflict with a patent or publication term that is incorporated by reference.
As used herein, “a,” “an,” or “the” means one or more unless otherwise specified.
Open terms such as “include,” “including,” “contain,” “containing,” and the like mean “comprising.”
The act of treating a textile can refer to, for example, one or more of: i) softening a textile; ii) applying a perfume to a textile; iii) applying a perfume to and softening a textile; iv) rendering the textile resistant to static build up during drying; or any combination thereof.
Some inventive aspects contemplate numerical ranges. Every numerical range provided herein includes the range endpoints as individual inventive aspects. When a numerical range is provided, all individual values and sub-ranges therein are present as if explicitly written out.
The terms “textile” and “fabric” can be used interchangeably.
The terms “fragrance” and “perfume” can be used interchangeably.
The term “about” is synonymous with the term “approximately,” and includes the recited number ±10% or ±5%. For example, “about 10” means 9 to 11. Also as an example, a temperature of approximately 50° C. means 45-55° C., or 47.5° C.-52.5° C. Unless indicated otherwise, all percentages indicated are percentage by weight.
The term “at least one,” refers to one or more, for example 1, 2, 3, 4, 5, 6, 7, 8, 9 or more. In particular, this information refers to the type of agent/compound and not to the absolute number of molecules. “At least one fragrance” therefore means that at least one type of fragrance is included, but that two or more different types of fragrances may also be included.
The term “water-soluble” refers to solubility in water at 20° C. of at least 1 g/L, or at least 10 g/L, or at least 50 g/L.

The terms “composition for fabric treatment,” and “CFT” may be used synonymously with the term “melt body.”
The term “melting temperature” refers to the temperature at which a composition converts from a solid form to a liquid form.
Compositions for Fabric Treatment (“CFTs”)
The present disclosure provides a composition for fabric treatment (“CFT”). The CFTs can be used, for example, to treat a textile.
The CFTs described herein can be used, for example, optionally with a laundry detergent, in the washing cycle of a laundry or fabric cleaning method and can provide softening to a fabric at any time during the fabric cleaning method, including at the beginning of the fabric cleaning method. The CFTs can further provide other beneficial ingredients including, but not limited to fragrance, to the washed fabrics. A method for treating textiles or fabrics, during which a composition of the present disclosure is added into a washer containing said textiles or fabrics, is a further subject of this application.
The CFT of the present disclosure comprises melt bodies.
In one aspect, the melt bodies can be between about 0.5 mm and about 10 mm, or between about 0.8 mm to about 7 mm, or about 1 mm to about 3 mm in any spatial direction.
In one aspect, the melt bodies can have a particle weight of between about 2 mg and about 150 mg, or between about 4 mg and about 60 mg, or between about 5 mg and about 10 mg.
The melt bodies are desirably solid at room temperature, for example, at about 25° C., and soluble in the usual working temperature ranges of a wash and/or rinse cycle, and can deliver a color fading protection to fabrics during a wash cycle.
In one aspect, the melt bodies are solid at temperatures from about 20° C. to about 40° C. In one aspect, the melt bodies are solid at temperatures of about 20° C., 25° C., 30° C., 35° C., or 40° C.
In one aspect, the melt bodies are uncoated, coated, waxed, powdered, or a combination thereof.
In one aspect, a method of making the melt bodies comprises: mixing a water-soluble carrier and a buffer system to form a mixture; adding a cationic polymer and a fragrance into the mixture; mixing the mixture; heating the mixture and obtaining a melt thereby; and cooling the mixture. In one aspect, the melt is shaped into individual particles comprising melt bodies. In one aspect, the viscosity of the mixture or melt, prior to cooling, is between about 1,000 mPas and about 10,000 mPas.
The melt bodies, can be of any desired shape. The shaping takes place before the melt is cooled. Solid, particulate shapes such as substantially spherical, hemi-spherical, lentil shaped, oblong shaped, figure-like, flake-shaped, cuboid, cylindrical, cone-shaped, spherical-cap-shaped or lens-shaped, hemispherical, disk-shaped or needle-shaped particles are suitable for SCTFs of the disclosure. For example, the particles may have a gummy-bear, figure-like design. Melt bodies having a hemispherical shape can advantageously be prepared by means of pastillation.
In one aspect, the melt bodies are uncoated, coated, waxed, powdered, or a combination thereof. Coatings known from the pharmaceutical literature, for example, are suitable as a coating agent. However, the CFTs may also be waxed, i.e. coated in a wax, or powdered with a powdered material, such as a release agent, for protection from caking (agglomeration). In one aspect, the coating does not contain PEG in a significant amount (>1% by weight based on the coating).
In one aspect, the melt bodies of the present disclosure can be used to deliver softening to textiles or fabrics. For example, the CFTs of the present disclosure can be combined with a conventional washing or cleaning composition and brought into contact with the textiles or fabrics during the washing cycle of a conventional washing and cleaning process to deliver softening and fragrance to the washed textiles.
Methods for preparing the melt bodies of the present disclosure are described in U.S. patent application Ser. No. 16/162,640, published as U.S. Application Publication Number 2019/0119608, which is incorporated by reference herein in its entirety.
In one aspect, the CFT of the present disclosure can be in the form of a pastille, a granule, a pellet, a powder, a pulverized powder, or a tablet. To make tablets or pellets, the ingredients in the CFTs can be blended together, for example, at room temperature, and compressed to form tablets or pellets. The blends can be dry powder blends. The CFT may be in an amorphous form, a crystalline form, or a partially crystalline form.

Water Soluble Carrier(s)
In one aspect, the CFT of the present disclosure can include a water-soluble carrier that is an aqueous salt wherein the water vapor partial pressure at a temperature of from about 30° C. to about 100° C., or usual working temperature ranges in a wash and/or rinse cycle, corresponds to the water (H2O) partial pressure of the saturated solution of the salt. The water-soluble carriers of the present disclosure demonstrate this behavior at a temperature of from about 30° C. to about 100° C., or from about 40° C. to about 90° C., or from about 50° C. and about 85° C., or from about 55° C. and about 80° C. The water soluble carrier is described in U.S. patent application Ser. No. 16/162,640, published as U.S. Application Publication Number 2019/0119608, which is incorporated by reference herein in its entirety.
In one aspect, the CFT of the present disclosure can include a water soluble carrier. In one aspect, the water-soluble carrier can be an aqueous salt. In one aspect, the water-soluble carrier can be sodium acetate or a hydrate thereof. In one aspect, water-soluble carrier can be water free sodium acetate. In one aspect, the water-soluble carrier can be sodium acetate trihydrate (Na(CH3COO).3H2O), sodium sulfate (Na2SO4. 10H2O), trisodium phosphate dodecahydrate (Na3PO4.12H2O) and strontium chloride hexahydrate (SrCl2.6H2O).
In one aspect, the water-soluble carrier is sodium acetate trihydrate (Na(CH3COO).3H2O).
In another aspect, the water-soluble carrier is water-free sodium acetate. In one aspect the water-free sodium acetate is used in combination with free water. In one aspect, sodium acetate trihydrate can form in situ when water-free sodium acetate is used in combination with free water. In such aspects, the water can be used in a substoichiometric or hyperstoichiometric amount based on the amount that is necessary to convert all of the sodium acetate into sodium acetate trihydrate, for example, in an amount of at least about 60% by weight, or at least about 70% by weight, or at least about 80% by weight, or at least about 90% by weight, or at about 100% by weight, or more, based on the weight of the CFT, which is the amount that is theoretically necessary to convert all of the sodium acetate into sodium acetate trihydrate (Na(CH3COO).3H2O).
In one aspect, the CFT comprises water in a hyperstoichiometric amount. Accordingly, if one aspect in which water-free sodium acetate is used in isolation, or in combination with a hydrate thereof, the trihydrate water is also used, the amount of water corresponding to at least the amount that would be stoichiometrically necessary to ensure that at least about 60% by weight of the total amount of sodium acetate and the hydrates thereof, preferably about 70% by weight, or at least about 80% by weight, or at least about 90% by weight, or at least about 100% by weight, based on the weight of the CFT, is in the form of sodium acetate trihydrate. In one aspect, the amount of water exceeds the amount that would be theoretically necessary to convert all of the sodium acetate into the corresponding trihydrate. This means, for example, that a composition that contains 50% by weight water-free sodium acetate and no hydrate thereof contains at least 19.8% by weight water (60% of 33% by weight that would be theoretically necessary to convert all of the sodium acetate into sodium acetate trihydrate.
In one aspect, the water soluble carrier can be present in an amount of from about 10% by weight to about 95% by weight, or from about 10% by weight to about 90% by weight, or from about 10% by weight to about 85% by weight, or from about 10% by weight to about 80% by weight, or from about 10% by weight to about 75% by weight, or from about 10% by weight to about 70% by weight, or from about 10% by weight to about 60% by weight, or from about 20% by weight to about 95% by weight, or from about 25% by weight to about 95% by weight, or from about 30% by weight to about 95% by weight, or from about 35% by weight to about 95% by weight, or from about 40% by weight to about 90% by weight, or from about 45% by weight to about 90% by weight of the CFT.

The following examples are illustrative and do not limit the scope of the disclosure of the claims.
The following tables contain example formulations (all figures given in % by weight).
All materials are considered greater than 99% active unless stated otherwise.
All Materials are Considered Greater than 99% Active Unless Stated Otherwise.
Two CFT formulations containing the ingredients and amounts listed in each of Tables 6 and 7 above, were prepared using the method below.
Sodium acetate trihydrate was heated to a temperature of 70° C. and stirred in water to form a mixture. The remaining ingredients were subsequently added to the mixture in the amounts listed in each of Formulas 21 and 22. Melt bodies or pastilles were prepared by dropping the liquid mixture (“melt”) onto a cooling plate of which the temperature was adjusted to room temperature (23° C.).
A softening test was designed to assess the softening effects on fabric samples after treatment of the fabrics with the composition of the present disclosure.
Softness may be described as “feel performance.” Feel performance can be characterized using the Extraction Energy Test Method (EETM), using a Phabrometer instrument (Nu Cybertek, Davis, Ca), which determines the amount of energy required to extract a cotton cloth, treated or untreated, through an orifice. Less energy is required to extract a cotton terry cloth treated with a rinse-added fabric care composition than to extract an untreated cotton terry cloth. The lesser the extraction energy required, the more lubricous or “silky” a fabric likely feels.
The EETM is as follows: circles of treated fabric are die cut into 11.2 cm circles using a hydraulic press. The fabric circles are placed between two 32 mm rings on the Phabrometer. The top ring is weighted with 1.36 kg and can be varied based on fabric type. A small probe pushes the fabric through the hole in the ring (perpendicular to the fabric surface). The instrument records the force (as voltage) needed to push the fabric through the ring for a total of 120 data points. The extraction energy is the area under the voltage-time curve plot. The EETM suggests that it takes less energy to extract cotton terry cloth treated with rinse added fabric care compositions versus an untreated cotton terry cloth. As noted herein, the lower the extraction energy, the more lubricous or “silky” the fabric likely feels.
An EETM using a Phabrometer instrument was employed to determine the softening effects of the CFT of the present disclosure on cotton knit fabric samples. An untreated sample and sample washed with a pastille that did not include cationic polymers or silicones were used as negative controls. Two different pastille dosages were tested: 45 g and 20 g. Three different percentages (by weight percentage of the pastille) of cationic polymers were tested: 0.15%, 0.25%, and 0.35%. Silicone (2%) was also combined in a pastille with 0.15% cationic polymer to determine the impact of the added silicone, in combination with the cationic polymer, on the softness of the sample fabrics. The results are shown in Table 8 below in descending order of the resulting softness from softest to harshest.
The first column provides the pastille composition. The second column indicates the statistical category of the knit fabric sample. Fabric samples with a shared letter (e.g., AB and BC) are not statistically different from each other, and those without a shared letter (e.g., AB and DE) are statistically different from each other. The third column provides the softness score of the sample fabric as measured by the Phabrometer. Higher softness scores indicate softer samples. As shown, Formula 28 is statistically different from Formula 30 because the statistical category does not share a letter (A and BC), whereas formula 28 and 29 are not statistically different from each other because the statistical category does share a letter A (A and AB).
Samples washed with pastilles containing 0.35% cationic polymer exhibited the highest softening performance according to the Phabrometer instrument (Formulas 28 and 29). Surprisingly, 45 g of pastille containing 0.15% cationic polymer and 2% silicone (Formula 30) resulted in increased softening performance, which is not statistically different from 20 g of pastilles comprising 0.35% cationic polymer (Formula 29) but was statistically different from the control pastille (Formula 34). Samples treated with pastilles that did not include either a cationic polymer or silicone (Formula 35) exhibited lower softening performance in comparison to the samples treated with the CFT of the present disclosure.
This example demonstrates that the addition of a cationic polymer of the present disclosure had a softening impact on the sample fabrics. This example further demonstrates that the addition of a cationic polymer in combination with a silicone, as disclosed herein, had a softening impact on the samples.
