The present disclosure related to treatment compositions and devices for treating textiles and fabrics. More particularly, the present disclosure relates to a treatment composition for extended release of fragrance from an absorbent substrate such as a dryer ball, and dryer balls containing the treatment composition.
Consumers who wash and dry their own laundry want their laundry to be dry, but also to feel soft, be free of static, and have a pleasant smell.
Fabric softener sheets, also known as dryer sheets, typically provide desired effects of fabric softening, static removal, and fragrance to laundry when included with the wet laundry in a clothes dryer. However, dryer sheets are disposable, and are typically discarded by a consumer user after one drying cycle. Some consumers prefer a softening and/or anti-static and/or fragrance product that can be used more than once.
Dryer balls, e.g., wool, plastic, or rubber balls which accompany wet laundry into the dryer, and tumble freely in the dryer drum with the washed fabrics, are commercially available for use as an alternative to dryer sheets. Some consumers choose to dry laundry with dryer balls as a way to shorten drying time of a load of laundry in a dryer, and/or provide fluffing to fabrics, and/or as a less wasteful alternative to dryer sheets. However, dryer balls do not reliably provide fabric softening, static cling prevention, and a pleasant fragrance to laundry.
Some wool dryer balls are available as pre-fragranced wool balls. These pre-fragranced wool balls, however, do not provide a long-lasting fragrance that can be experienced by consumers when the article is worn or used if the laundry is stored for a period of time before wear or other use.
It would be desirable if wool and other dryer balls could be provided with long lasting fragrance that would provide dried clothing and other laundry with a long-lasting pleasant smell which could be experienced by consumers during wear/use of fabrics, even if such wear/use occurs long after drying of the clothing and other laundry.
Accordingly, a need exists for improved devices and methods for providing the aforementioned benefits and additional benefits of less waste and being more environmentally friendly to a substrate used as a dryer ball in a dryer.
The foregoing is achieved by a treatment composition that can be applied to absorbent substrates such as dryer balls to enable extended fragrance release from fabrics dried using the substrates.
In one aspect, the invention provides a device for treating fabrics and textiles in a dryer comprising an absorbent substrate; and a fragrance composition dispersed on or within the substrate, the fragrance composition comprising free fragrance, and encapsulated fragrance. The substrate contains about 0.02% to about 2.0% by weight of free fragrance and about 0.005% to about 2.5% by weight of encapsulated fragrance, based on a total weight of the substrate without fragrance. In preferred embodiments, the substrate is a wool ball. In certain embodiments, ratio of free fragrance to encapsulated fragrance is about 1:0.3 to 1:2, or 1:1 to about 1:2.
Another aspect of the invention is a treatment composition used on a substrate such as a wool dryer ball, which comprises an aqueous carrier, free fragrance, and encapsulated fragrance. The treatment composition comprises about 0.1 wt. % to about 5 wt. % free fragrance and about 0.1 wt. % to about 10 wt. % encapsulated fragrance. In certain embodiments, a ratio of free fragrance to encapsulated fragrance is about 1:0.3 to 1:2, or about 1:1 to about 1:2. The treatment composition further comprises at least one suspending polymer, which desirably is selected from the group consisting of a hydrophobically-modified alkali swellable emulsion polymer (HASE), an alkali swellable emulsion polymer (ASE), a cationic polymer, an anionic polysaccharide polymer, and any combination thereof. Most preferably, the suspending polymer is a HASE; and comprises about 0.01 wt. % to about 3.0 wt. % of the treatment composition. The composition may further comprise a neutralizing agent and/or an emulsifier, and additionally, one or more of an odor capturing agent, a softening agent, an anti-static agent, a color protection agent, a UV protector, an anti-pilling agent, a disinfecting/sanitizing agent, a scouring agent, and a mosquito repellant, or any combination thereof. The composition may also include one or more of a colorant and/or a salt.
A further aspect of the invention is a kit for treating textiles in a dryer, which comprises one or more absorbent balls; a treatment composition comprising free fragrance, encapsulated fragrance, and an aqueous carrier; and an applicator for applying the treatment composition onto or within the absorbent balls. The balls preferably are comprised of wool. The kit preferably contains a plurality of balls. The applicator is selected from the group consisting of a sprayer, a dropper, and a syringe. In certain embodiments, the applicator is capable of dispensing about 4 g to about 15 grams, more preferably about 6 g to about 12 g of the treatment composition to the ball with each application. In some embodiments, the applicator dispenses an amount of treatment composition sufficient to provide one wool ball with about 0.04% to about 0.85% by weight of free fragrance and about 0.01% to about 1.25% by weight of encapsulated fragrance, based on a total weight of the wool ball without fragrance.
The following detailed description is merely exemplary in nature and is not intended to limit the product described, or the method for producing or using the same. Furthermore, there is no intention to be bound by any theory presented in the preceding background or the following detailed description.
As described herein, there is a need for an improved device for providing benefits to laundry for use in a dryer that overcomes the drawbacks of currently available devices and methods. According to various embodiments described herein, the devices described herein provide advantages over the prior art by providing a simple and ecological way to impart one or more benefits to fabrics and garments during a drying cycle. In particular, a number of benefits can be provided to laundry via the re-usable devices and treatment compositions described herein. In embodiments, the consumer can choose the preferred combination of benefits. Such benefits include, but are not limited to: shortened drying time, fluffing of fabrics, softness, fragrance, and static lessening/removal.
The terms “garment,” and “laundry” as used herein, encompass all textile and fabric items typically washed in a washing machine and dried in a clothes dryer, and include clothing, as well as kitchen, table, bedroom, and bath fabric items such as sheets, towels, blankets, and other products primarily made of textiles or fabrics.
The terms “fragrance” and “perfume” as used herein are equivalent terms indicating a composition with a pleasant odor.
The term “about” as used in connection with a numerical value throughout the specification and the claims denotes an interval of accuracy, familiar and acceptable to a person skilled in the art. In general, such interval of accuracy is ±10%. Thus, “about ten” means 9 to 11. All numbers in this description indicating amounts, ratios of materials, physical properties of materials, and/or use are to be understood as modified by the word “about,” except as otherwise explicitly indicated.
The wt. % amounts in the specification refer to the amounts of an active ingredient in the final beneficial composition. For example, the encapsulated fragrance compositions are typically provided by the vendors as aqueous suspensions, typically at about 30 wt. % solid encapsulates. The active ingredient refers to the solid encapsulates.
Embodiments will now be described in more detail with reference to the Figures.
Absorbent Substrate
The absorbent substrate 10 can be a variety of shapes, sizes, and material. In some embodiments, the absorbent substrate 10 is wool. In some embodiments, the absorbent substrate 10 is plastic. In some embodiments, the absorbent substrate 10 is rubber. In one embodiment, as shown in
Preferably, dryer ball 14 comprises, consists essentially, or consists of wool or another hydrophilic material. The wool can be sheep's wool or from other types of animals such as, for example Corriedale wool or Cotswold wool, or from wool obtained from other animals, such as for example alpacas, or any combination of wool thereof. Other shapes, sizes, and materials are contemplated.
In certain embodiments, the ball 14 may be formed from wool yarn which has been twisted or wound into a ball and felted by washing and drying the ball several times in succession. Typically, wool dryer balls are hard and dense, and are similar in size to plastic dryer balls (e.g., about the size of a tennis ball or smaller). In some embodiments, the piece of wool material is folded into a substantially spherical wool ball having a circumference in the range of 43 cm to 53 cm. The wool material may be felted. In some embodiments, the spherical wool ball 14 has a diameter of about 4 inches and weighs around 60 to 110 g.
Other exemplary embodiments and materials that can be used for dryer ball 14 are described in U.S. Patent Application Publication No. 20190309464, the contents of which is incorporated herein by reference. Other suitable balls are described in U.S. Pat. Nos. 4,014,105; 4,567,675; and 7,441,345.
Absorbent substrate 10 is provided with a treatment composition 12 disposed on the ball and/or within the ball.
As illustrated in
The treatment composition 12 can be applied with applicator 19 in, e.g., an even mist, in separated, discrete areas, or concentrated in one location.
After application, some of the treatment composition 12 may penetrate the interior of the ball 14 via diffusion or other fluid transfer mechanisms. Alternatively, the treatment composition 12 can be directly applied to the interior of the ball 14 using a syringe and needle or other instrument capable of piercing the outer surface of the ball, as illustrated in
In some embodiments, the treatment composition 12 may be contained in a wrap that is disposed around an exterior surface of the ball 14. For instance, the laundry ball may include a shell that is water permeable, where the shell forms an enclosure defined by an inside of the laundry ball. An insert is enclosed within the enclosure, where the insert includes a laundering beneficial compound. In some embodiments, the insert may be partially exposed outside the ball but not fall out of the ball. The shell is water permeable, or porous, such that water can flow through, but objects larger than the size of the pores cannot flow through the shell. The shell may be made of a fabric, such as wool, cotton, polyester, silk, or other materials or combinations of materials in various embodiments. The pores are then the spaces that are disposed between and defined by the threads of the fabric. In an alternate embodiment, the shell may be polymeric, and include a polymer such as a polyethylene, polypropylene, polyethylene-polypropylene copolymers, or other polymers. The shell may be a combination of different materials in some embodiments, such as a fabric wrapped over a polymeric base, in whole or in part, or different types of materials woven together or positioned in different locations on the shell. The shell may include rubber, wood, or other materials in various embodiments. The shell forms the outer portion of the substrate 10 in an exemplary embodiment, so the outer dimensions of the shell also essentially determine the outer dimensions of the substrate 10.
Optionally, the dryer ball 14 can include a wrap disposed around an exterior surface of the ball. In some embodiments, the wrap is treated with a treatment agent. The wrap can be a continuous band. The wrap can have a first end and a second end such that the first end and the second end are configured to be releasably attached to the exterior surface of the ball.
Treatment Composition
The treatment composition 12 contemplated herein comprises a free fragrance, and an encapsulated fragrance, that is delivered to the ball via a carrier. The treatment composition can also contain one or more agents that provide laundering benefit. The treatment composition is formulated with an aqueous carrier, emulsifier, and a suspending agent so that it is stable and can be readily disposed on and within ball 14. It is an advantage that the treatment composition is in liquid, rather than powder, form so that it can be easily applied to and retained by hydrophilic ball materials. Optional ingredients may include an odor capturing agent, a softening agent, an anti-static agent, a color protection agent, a UV protector, an anti-pilling agent, a disinfecting/sanitizing agent, a scouring agent, and a mosquito repellant, or any combination thereof.
In certain preferred embodiments, the amount of treatment composition on the ball is about 5.0% to about 10.0% by weight of the ball, more preferably about 6.0% to about 9.0% by weight of the ball. The amount of treatment composition on the ball is calculated as add on based on the weight of the ball measured within 5 minutes after the treatment is applied.
In some embodiments, ball 14 can be pretreated with treatment composition 12 and packaged in moisture resistant packaging shortly after the treatment composition is applied. For instance, the balls can be packaged in mylar bags after the treatment composition is applied. In that case, the amount of treatment composition on the ball is about 5.0% to about 10.0% by weight of the ball, more preferably about 6.0% to about 9.0% by weight of the ball. The amount of treatment on the ball is calculated as add on based on the weight of the ball measured within 5 minutes of removing from the packaging.
In some embodiments, the ball 14 will weigh from about 60 g to about 110 g, more preferably about 65 to about 100 g when stored in ambient laboratory conditions of about 70° F. The weight of the ball 14 will, in certain circumstances, such as where the ball is comprised of wool or another absorbent material, be dependent on the ambient humidity conditions. Accordingly, the amount of treatment composition applied should be determined using starting weight of a ball after it has equilibrated with ambient conditions and shortly before treatment composition is applied.
Free Fragrance
The terms “free fragrance” or “fragrance oil” refers to any type of free, unencapsulated fragrance known to those of skill in the art. The fragrance may be an oil fragrance, an essential oil, botanical extracts, synthetic fragrance materials, or other compounds that provide a desirable odor.

In some embodiments, the fragrance can be mixtures of various fragrances, which can be referred to as a perfume or perfume oil. Perfume oils of this kind may also contain natural fragrance mixtures, as are obtainable from plant sources.
In some embodiments, the fragrance can be a fragrance precursor. “Fragrance precursor” refers to compounds which only release the actual fragrance following chemical conversion/separation, for example, when exposed to light or other environmental conditions, such as pH, temperature, etc. Treatment agents of this kind are often referred to as pro-fragrances.
Other fragrances known in the art, or any fragrance commercially available from a fragrance supplier (e.g., Firmenich, Givaudan, IFF, Symrise, Agilex etc.), or any combination of such fragrances, may also suitably be used in the treatment compositions and methods disclosed herein.
In some embodiments, the free fragrance is present in the treatment composition from about 0.1 wt. % to about 20 wt. %, or from about 0.5 wt. % to about 20 wt. %, or from about 0.5 wt. % to about 15 wt. %, or from about 1 wt. % to about 5 wt. %, based on the volume of the treatment composition.
In some embodiments, the free fragrance is, for example, present in the treatment composition in an amount of about 0.5 wt. %, about 1.0 wt. %, about 1.5 wt. %, about 2.0 wt. %, about 3.0 wt. %, about 4.0 wt. %, or about 5.0 wt. %. In some embodiments, the free fragrance is, for example, present in an amount from about 0.1 wt. % to about 5 wt. %, from about 0.5 wt. % to about 4.5 wt. %, about 0.5 wt. % to about 4 wt. %, from about 1.0 wt. % to about 4 wt. %, or from about 1.5 wt. % to about 4 wt. %.
In some embodiments, the free fragrance is present on or within the ball 14 in an amount from about 0.025 g to about 1.0 g, more preferably from about 0.05 g to about 0.8 g, most preferably from about 0.1 g to about 0.4 g, or from about 0.1 g to about 0.2 g, based on the total weight of the ball.
In certain embodiments, the amount of free fragrance on the ball 14 is about 0.02% to about 2.0% by weight of the ball, more preferably about 0.045% to about 1.5%, most preferably or about 0.1% to about 0.75%, or about 0.1% to about 0.5% by weight of the ball. The weight percent on the ball is calculated as add on based on the weight of the ball before any treatment composition is applied.
In one embodiment, the fragrance has a melting point that is in the range of from about 35° C. to about 75° C.
Encapsulated Fragrance(s)
The treatment composition contains one or more encapsulated fragrances. The term encapsulated fragrance refers to fragrance that is encapsulated for example, in a microcapsule or a nanocapsule. The microcapsules and nanocapsules can be water-soluble or water insoluble.
Examples of encapsulated fragrances are described in, for example, U.S. Pat. Nos. 6,024,943, 6,056,949, 6,194,375, 6,458,754 and 8,426,353, and US 2011/0224127 A1 and US 2017/0121648, each of which is incorporated by reference in its entirety.
Encapsulation of fragrances prevents the fragrance from being released prematurely. The encapsulation may be ruptured at some time period after application to the garment, so fresh fragrance may be provided significantly after a garment is removed from a washing machine. The encapsulation may be ruptured by a wide variety of activities, such as physical contact from movement, melting, degradation from sunlight, degradation from oxidation, or other reasons. The encapsulation may be formed by aminoplast or cross-linked gelatin, polymeric materials, or other materials.
In some embodiments, the encapsulated fragrance is present in an amount from about 0.1 wt. % to about 10 wt. %, from about 0.1 wt. % to about 8 wt. %, from about 0.1 wt. % to about 6 wt. %, from about 0.1 wt. % to about 4 wt. %, or from about 0.1 wt. % to about 3 wt. % of the treatment composition. In some embodiments, the encapsulated fragrance is present in an amount from about 0.75 wt. % to about 7.5 wt. %, 1 wt. % to about 5 wt. %, from about 1 wt. % to about 4 wt. %, or from about 1 wt. % to about 3 wt. %.

In some embodiments, the repellent is present on/in the ball in an amount from about 0.1 g to about 8.0 g, or from about 0.5 g to about 7.0 g, or from about 1 g to about 6 g, or from about 2 g to about 5 g, or from about 3 g to about 5 g, or from about 4 g to about 5 g, based on the total weight of the ball.
Additional suitable fabric treatment agents are disclosed in U.S. Pat. No. 7,456,145, which is herein incorporated by reference in its entirety.
Kits Comprising the Device
In some embodiments, a kit may include one or more dryer balls 14 (e.g., wool, plastic, or rubber) and the treatment composition to be disposed on the one or more dryer balls. In some embodiments, the kit includes one or more balls 14 pretreated with a first treatment composition 12. In some embodiments, the kit further includes a container (e.g., a pour bottle, squirt bottle, spray bottle, etc.) confining a volume of a second treatment composition for disposing on the one or more balls 14, and an applicator 19. This may be used, for example, to “re-charge” the balls with the treatment composition or add an additional treatment agent to the ball.
In certain embodiments, the kit contains 3 balls. In other embodiments, the kit contains 4 balls.
In some embodiments, the second treatment composition is different than the first treatment composition. In some embodiments, the second treatment composition is the same as the first treatment composition.
Methods of Use
Treating a fabric or 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.
In one embodiment, the method further includes running the dryer on a nonheated (i.e., fluff) cycle.
In certain embodiments, the method releases fragrance onto textiles in the dryer. In certain embodiments, a ball delivers about 25 mg to about 1 g fragrance to textiles in a drying cycle. In certain embodiments, a ball delivers about 100 mg to about 500 mg of fragrance, more preferably about 120 mg to about 250 mg to textiles in a drying cycle.
In some embodiments, a ball delivers about 25 mg to about 500 mg free fragrance to textiles in a drying cycle. In certain embodiments, a ball delivers about 50 mg to about 250 mg of free fragrance, more preferably about 70 mg to about 205 mg free fragrance to textiles in a drying cycle.
In certain embodiments, a ball delivers about 50 mg to about 2 g encapsulated fragrance to textiles in a drying cycle. In certain embodiments, a ball delivers about 100 mg to about 1 g of encapsulated fragrance, more preferably about 120 mg to about 500 mg encapsulated fragrance to textiles in a drying cycle.
In some embodiments, about 0.1 to about 4.0 g of fragrance is delivered by one or more balls in a drying cycle. In certain embodiments, about 0.4 to about 2.0 g, more preferably about 0.5 to about 1.0 g of fragrance is delivered by one or more balls in a drying cycle.
In certain embodiments about 100 mg to about 2 g free fragrance is delivered by one or more balls in a drying cycle. More preferably, about 200 mg to about 1 g of free fragrance, more preferably about 250 mg to about 850 mg free fragrance is delivered by one or more balls in a drying cycle.
In some embodiments, about 200 mg to about 8 g encapsulated fragrance is delivered by one or more balls in a drying cycle. In certain embodiments, about 400 mg to about 4 g of encapsulated fragrance, more preferably about 450 mg to about 1 g encapsulated fragrance is delivered by one or more balls in a drying cycle.
The absorbent substrate 10 provides a both a fragrance and mechanical benefit in the drying cycle of the dryer. Moreover, the fragrance benefit can continue for up to 7 days, more preferably up to 1 month, most preferably up to 3 months. Without wishing to be bound by theory, the encapsulated fragrance is released when the fabric is rubbed by a user after it has been removed from the dryer. The treatment composition contains sufficient amounts of free and encapsulated fragrance to deliver a noticeable scent to the consumer for up to a month after laundering.
The following examples are illustrative, but not limiting, of the present embodiments. Other suitable modifications and adaptations of the variety of conditions and parameters normally encountered in the field, and which would be apparent to those skilled in the art, are within the spirit and scope of the disclosure.
500 g of a suspension having the composition in Table 1 was prepared by mixing the ingredients with a mixer at 4500 rpm for 3 minutes.
2A: Snuggle® Blue Sparkle® Dryer Sheets. These dryer sheets had a similar fragrance scent profile to the fragrances used in Composition 1.
2B: No encapsulated fragrance. This formula included 2% free fragrance and no encapsulated fragrance suspension.
The composition of Examples 1 and 2 were applied to the surface of unscented wool balls having an average dry weight 80-100 g using a spray bottle with a wet-basis add on target of 6 g.
The loaded balls were weighed on a lab scale within 5 minutes after application of the treatment composition. Bags were stored in open air, in plastic bags and in Mylar bags. The weight of the balls was recorded after 24 hours of storage. The results are shown in Table 2.
Balls stored in plastic and Mylar bags lost minimal amounts of treatment composition. In contrast, balls stored at ambient conditions appeared to lose a large portion to all of the treatment composition.
A MAYTAG® Epic Z electric tumble clothes dryer capable of internal temperatures up to approximately 150° F. was used for experiments. The test fabrics were 12″×12″ 100% Cotton, terry towels. Sixty towels were washed with All® free clear detergent then tumbled with 4 wool balls of Example 3, loaded with the treatment composition of Example 1, for 60 minutes. A cycle with unscented wool balls was run as a comparison.
A panel of 10-15 (different panels overall), including a mix of trained and untrained “average consumers”, rated the smell of the towels laundered and dried according to Example 4 at various time points (fresh dry, 7 days, 1 month). An intensity rating of 0-10 was awarded before and after rubbing the towels with 10 being the highest intensity and 0 being no fragrance detected.
Results are shown in Table 3. An average of 5 consumer ratings was used for each data point. The consumers were randomly selected at each timepoint.
Alternative formulas having the compositions in Table 4 were prepared by mixing the ingredients with a mixer at 4500 rpm for 3 minutes.
The weight of 4 balls containing 6 grams of treatment Composition 1 and 6 grams of Composition 6B were measured after storage (no secondary containment) at various temperatures at 0, 1, 2 3, and 4 weeks. Results for composition 1 are shown in Table 5 and for composition 6B in Table 6.
Having described the invention with reference to a particular composition and the like, it will be apparent to those of skill in the art that it is not intended that the invention be limited by such embodiments, and that modifications can be made without departing from the scope of the invention.
