Description

A CONTROLLED RELEASE CLEANSING TABLET CONTAINING BIOLOGICAL ACTIVES

TECHNICAL FIELD

The disclosure relates to solid controlled release compositions containing an alkalinity source, a sugar alcohol, and biological actives, including enzymes and/or spores. The compositions provide alkalinity cleaning formulations suitable for cleaning fats, oils, grease and/or other organic waste, including in methods for dosing into a reservoir to generate a use solution from the controlled release composition to clean fats, oils, grease and/or other organic waste. The methods are suitable for use in cleaning various reservoirs where waste water flows through and needs sustained cleanliness, including a sink, bowl, drain, drain outlet, disposal, tank, toilet bowl, fluid line, pipe or combinations thereof, preferably an oil separation tank.

BACKGROUND

The background description provided herein gives context for the present disclosure. Work of the presently named inventors, as well as aspects of the description that may not otherwise qualify as prior art at the time of filing, are neither expressly nor impliedly admitted as prior art.

Sufficient cleaning performance has not been obtained by chemical methodologies alone for various hard to clean surfaces, including reservoirs for oil separation, grease traps, toilets, tanks, drains, pipes, and the like. Moreover, people do not want to manually clean these surfaces as they can become heavily soiled, have unpleasant odors, etc.

Meanwhile, consumers have a desire to employ biological methodologies for cleaning, for example, from a natural, eco-friendly, sustainability, etc. focus. However, biological solutions can be costly and methods of using these solutions often require an extended contact or treatment time to obtain visible cleaning performance. There is also a challenge in incorporating biological actives into solid compositions. This can be challenging, not only because the compatibility between biological actives and chemical components, but also due to challenges in pressing such actives into stable solids. The state of the art has proposed various complicated solutions, including multi-phased compositions and other solutions to separate the biological actives within compositions. However, these present formulation and manufacturing challenges that can further increase the cost of products.

Thus, there exists a need in the art for providing controlled release compositions that can provide biological actives to impact desired cleaning efficacy.

Other objects, embodiments and advantages of this disclosure will be apparent to one skilled in the art in view of the following disclosure, the drawings, and the appended claims.

COMPOSITIONS

According to embodiments, the solid compositions comprise, consist of and/or consist essentially of a homogenous composition of an alkali metal alkalinity source, a sugar alcohol, and at least one biological active comprising an enzyme composition and/or a spore, and optionally additional functional ingredients. Exemplary solid controlled release compositions are shown in Table 1 in weight percentage. While the components may have a percent actives of 100%, it is noted that Table 1 does not recite the percent actives of the components, but rather, recites the total weight percentage of the raw materials (i.e. active concentration plus inert ingredients) .

TABLE 1

In some embodiments, the solid controlled release compositions are homogenous solid compositions. In further embodiments, the solid controlled release compositions are a single phase homogenous solid.

In an embodiment, the solid controlled release compositions do not include distinct or separate components thereof. The solid controlled release compositions are referred to as a single-part or a one-part system. This is beneficial and distinct from prior controlled release compositions which are controlled release as a result of encapsulation, coating or membranes, core-shell structures, distinct layers of components within the solid, separate dosing of components, such as in liquid formulations, or having distinct compartments for physical separation of components (e.g. sachets, pouches or the like) and must then be combined with a distinct composition or other composition to provide the desired activity at the controlled release rate.

The solid compositions are preferably pressed solids, e.g. pressed into a solid form. In some embodiments, the composition may be dispensed from the mixture by forming, pressing, casting, extruding, or other suitable means, whereupon the composition is pressed or hardens to a solid form. The structure of the composition may be further characterized according to its hardness, melting point, material distribution, crystal structure, and other like properties according to known methods in the art. Generally, a solid controlled release composition is substantially homogeneous with regard to the distribution of ingredients throughout its mass and is dimensionally stable. As referred to herein, dimensional stability refers to a change in dimension of the solid composition (such as from cracking and/or swelling) greater than 3%as measured in length, height and/or width (depending upon the method of solidification, shape of the solid detergent composition and/or formulation into any type of capsule or other component for dispensing) at the evaluated temperature and time conditions outlined herein and at ambient humidity of the evaluated atmosphere. The average growth numbers in length, height and/or width represent the change in dimension.

In embodiments, the solid controlled release compositions are designed to release a certain portion or amount of the solid composition over a desired period of time during use. In an exemplary embodiment, the solid controlled release compositions provide a consistent concentration of the cleaning composition from about 1 ppm to about 500 ppm in a use solution (including all ranges therebetween) . Accordingly, a skilled artisan will ascertain from the disclosure that the size of the solid controlled composition can be suited for the volume of a reservoir and/or type and extent of soils contained therein for cleaning to provide controlled release over a period of time, such as on a daily basis (or other increment of time) .

In an embodiment, the solid controlled release compositions provide at least 10 hours, at least 12 hours, at least 15 hours, at least 20 hours, or at least 24 hours of controlled release of the cleaning composition. In an embodiment, the solid controlled release compositions provide at least 10 hours, at least 12 hours, at least 15 hours, at least 20 hours, or at least 24 hours of controlled release of the cleaning composition that is provided in a solid tablet or dosage form that is at least about 50 grams. As one skilled in the art will ascertain, the larger the solid composition is formulated (e.g. 50 grants, 100 grams, 250 grams, or larger) an increase in the amount of time the controlled release the solid composition can provided and is included within the scope of the compositions, methods and systems. Without being limited by a particular mechanism of action, in some embodiments about at least a 50 gram tablet size will provide controlled release of the cleaning composition for the desired amount of time.

METHODS OF USE

The solid controlled release compositions are suited for cleaning hard surfaces and objects having fats, oils, grease and/or other organic waste. The solid controlled release compositions are efficacious in cleaning and removing soils from such surfaces and objects without the need for significant use of or any mechanical cleaning efforts. In a particular embodiment, the solid controlled release compositions are efficacious in removing fats, oils, grease and/or other organic waste from a surface that has waste water flowing through and needs sustained cleanliness.

The methods of cleaning fats, oils, grease and/or other organic waste from surfaces or objects comprises: (a) dosing a solid composition into a reservoir to generate a use solution comprising from about 1 ppm to about 500 ppm of the composition when contacted by water, and (b) cleaning the fats, oils, grease and other organic soils. In some embodiments the organic soils are bacterial deposits.

As referred to according to the methods steps the solid composition is a controlled release product and is either (i) the solid composition as described herein or (ii) a solid cleaning composition as described herein that does not include (i.e. excludes) a biological active.

In an embodiment, the reservoir is a hard surface, including for example, a sink, bowl, drain, drain outlet, disposal, tank, toilet bowl, fluid line, pipe or combination thereof. In a further embodiment, the tank is an oil separation tank. Each of these embodiments reservoir has waste water flowing through it or over it and needs sustained cleanliness from various soils. The methods beneficially, reduce or eliminate the need for mechanical cleaning efforts, such as by a person or machine to apply force, contact and/or any means to mechanically remove such fats, oils, grease and/or other organic waste.

Exemplary industries in which the methods of the present disclosure can be applied include, but are not limited to: the food and beverage industry, food service industry (e.g. restaurants) , healthcare industry, oil processing industry, industrial agriculture and ethanol processing industry, pharmaceutical manufacturing industry, and various others having hard surfaces, objects and reservoirs where waste water flowing through and needs sustained cleanliness and/or where cleaning compositions also require mechanical force to clean and remove soils. In a still further embodiment, consumer markets including household applications can benefit from the methods of the present disclosure, such as for cleaning household drains.

In some aspects, the methods of using the solid controlled release compositions include dosing a solid composition into a reservoir to generate a use solution comprising from about 1 ppm to about 500 ppm of the composition when contacted by water. In embodiments the solid compositions are controlled release such that the solid composition dissolves over time to continually provide a use solution concentration between about 1 ppm to about 500 ppm, about 10 ppm to about 500 ppm, about 1 ppm to about 400 ppm, about 10 ppm to about 400 ppm, about 1 ppm to about 300 ppm, about 10 ppm to about 300 ppm, about 1 ppm to about 200 ppm, about 10 ppm to about 200 ppm, and including all ranges therebetween.

The dosing step can be any known method of applying or contacting the compositions to the surface, object or reservoir. In some embodiment, a single solid controlled release composition can be manually added to a reservoir. In such embodiment, the composition can be added to a reservoir that is either empty or already has water contained therein. For example, dosing can include immersing the solid composition into a reservoir already containing a volume of water or adding the solid composition into a reservoir before a volume of water is added. Dosing can be manual or by machine.

In embodiments, the solid composition dissolves over a period of time of at least about 12 hours, or at least about 24 hours, to maintain the use solution having a concentration from about 1 ppm to about 500 ppm of the composition.

In embodiments, the solid composition dissolves over a period of time to provide a pH of the use solution between about 8 to about 12.

In embodiments, the solid composition can be dosed every 12 hours, every 24 hours, or once per day. The dosing rate of the solid composition will vary depending upon the reservoir, the extent of the fats, oils, grease and/or other organic waste on the surfaces, and further volume and rate of waste water passing there through. One skilled in the art will readily be able to determine the dosing rate for a particular reservoir based on the size (grams to kilograms) of the solid composition and these factors to ensure sufficient removal of the fats, oils, grease and/or other organic waste for desired cleanliness.

In embodiments of the methods, the water generating the use solution has a temperature between about 10℃ and about 100℃. In preferred embodiments, the water generating the use solution has an ambient temperature.

In some embodiments, the methods can optionally comprise a rinsing step. The rinsing step can comprise water, at ambient and/or at elevated temperatures, e.g. about 70℃to about 100℃.

Beneficially, the methods fats, oils, grease and/or other organic waste on the surfaces, and moreover they reduce clogging by dissolving organic waste buildup, fouling, odor, oils and other accumulation on hard surfaces. Still further, the methods reduce the frequency of grease trap pump outs. Still further, depending upon the location of the reservoir within a particular facility, the methods can further beneficially reduce fruit flies and other unwanted pests around the surface. Still further, the cleaning methods reduce or eliminate the need for mechanical cleaning.

As a still further benefit, the methods reduce use of water (i.e. water consumption) compared to conventional cleaning methods. In some embodiments, the methods reduce water usage by at least about 10 L/day to about 40 L/day.

The following solid controlled release composition in Table 2 was evaluated in the Examples formulated as a 60 gram pressed tablet.

TABLE 2

EXAMPLE 1

Commercially available cleaning compositions (liquids and solids) were evaluated for cleaning efficacy in locations having disposal from a coffee maker compared to a kitchen waste disposer (in an effort to gauge comparison of soil removal requirements from a commercial /industrial site compared to a consumer site. Initial screening of these diverse applications of use illustrated that a robust cleaning composition is required for commercial applications, such as those having oil separation tanks compared to a consumer application. In particular, it was identified that a controlled release product was most desirable to provide all day, lasting cleaning efficacy against fats, oils, grease and/or other organic waste. It was further identified that the cleaning efficacy must include ability to remove clogs, odor and clean all surfaces, including the inner surface of pipes.

Based on the initial screening, the solid controlled release composition was compared to commercially-available consumer products that are sold as powders and tablets. The tablets used as Control were three commercially-available consumer products known to be effective to removes odor-causing residues. For the dosing, 3 tablets were used. The cleaning component is a surfactant. The products provided outstanding visual effect but were not functional in soil removal.

An oil separation tank was used as the test site to compare efficacy of the solid controlled release composition to the commercially-available consumer product. The drain outlet was blocked with a cloth. Each solid composition was added (on separate evaluation trials) to the reservoir and hot tap water (45℃) was added to the reservoir to flush the composition until the volume reached above the composition and the sink reservoir was immersed. Then the composition was allowed to dissolve for 15 minutes and the reservoir was evaluated (upper and lower sides and the drain itself) using an endoscope to assess cleaning of the drain itself (i.e. soils in the drain) compared to the pre-cleaning condition of the drain.

The Control (commercially-available consumer product) did not result in any visual cleaning effect in the drain, whereas significant cleaning efficacy to remove soils was observed from the drain with the solid controlled release composition. Notably the Control had strong visual or olfactory effects, including abundant foam and a pleasant aroma but hardly have cleaning effect.

EXAMPLE 2

An additional evaluation of the solid controlled release composition was conducted in an oil separation tank to assess the controlled release efficacy. A single 60 gram pressed tablet was added to a reservoir of an oil separation tank and allowed to dissolve and release composition to provide the desired concentration range of 1 ppm to 500 ppm over time in a use solution. Waste water was allowed to flow through the oil separation tank as in normal use conditions for a period of 17 hours. Throughout the cleaning process the slow and consistent dissolution of the composition provided sustained and commercially-acceptable cleaning performance to remove fats, oils, grease and/or other organic waste.
