It would be advantageous to have cleaning compositions, which may self-adhere to a hard surface, such as a toilet bowl or shower. In particular, it may be desirable to have such compositions in the form of a gel, in some instances with a high “hardness” property allowing them to be handled easily by a consumer without significant deformation. It may also be desirable for such gels to have a relatively low gel melt temperature, in order to facilitate processing of the gel composition during manufacturing. Additionally, such compositions may advantageously be transparent, have good foaming properties, and/or be compatible with a wide range of additional ingredients such as fragrance, dyes, surface-modifying polymers, antimicrobial agents, and other cleaning agent auxiliary ingredients.
The present application relates generally to the field of cleaning compositions and, in particular, cleaning compositions which may be especially useful for cleaning hard surfaces, such as the inside surface of a toilet bowl. The present application provides cleaning compositions, which may commonly self-adhere upon application to a hard surface, typically a vertical or inclined hard surface. The self-adhering cleaning compositions may include (a) an adhesion promoter, (b) a glycine betaine ester, and (c) water. Often, the adhesion promoter includes at least one compound including one or more polyalkoxy groups. The glycine betaine ester may be a compound of formula (I):
Me3N+—CH2—C(O)—O—RX− (I)
wherein R is an aliphatic group having 8 to 22 carbon atoms and X− represents an inorganic or organic anion. Commonly, the composition is a gel. In some embodiments, the gel has a gel melt temperature of about 55-80° C. The gel may have a viscosity at 25° C. of at least about 150,000 cP. In some embodiments, the gel may have a hardness of at least about 150 g.
The adhesion promoter may include at least one compound including one or more polyalkoxy groups. In some embodiments, the adhesion promoter may include an ethoxylated C12-C30 aliphatic alcohol having an average of about 15 to 100 ethylene oxide units. In some embodiments, the polyalkoxy group may include ethyleneoxide-propyleneoxide block copolymer. In some embodiments, the adhesion promoter may include polyethylene glycol. In some embodiments, the adhesion promoter may include at least one polysaccharide and/or synthetic polymer resin.
The cleaning composition may include other ingredients such as one or more of mineral oil, polyol humectant, an antimicrobial agent, and a fragrance component. Optionally, the composition may include a surfactant selected from nonionic, anionic, cationic, zwitterionic, and/or amphoteric surfactants and mixtures thereof, wherein the surfactant is different from the adhesion promoter.
In another aspect, the present technology provides a composition for treating a hard surface that includes (a) at least one adhesion promoter, which includes at least one polyalkoxy group; (b) a glycine betaine ester of formula (I):
Me3N+—CH2—C(O)—O—RX− (I)
wherein R is an aliphatic group having 8 to 22 carbon atoms; and (c) water. The composition is typically a gel, which has a gel melt temperature of about 55-80° C. and a viscosity at 25° C. of at least about 150,000 cP.
In another aspect, the present technology provides a composition for treating a hard surface including (a) at least one adhesion promoter, which includes at least one polyalkoxy group; (b) a glycine betaine ester of formula (I):
Me3N+—CH2—C(O)—O—RX− (I)
wherein R is an aliphatic group having 8 to 22 carbon atoms; and (c) water; wherein the composition is a gel having a hardness of at least about 150 g and a gel melt temperature of about 55-80° C.
In some embodiments, it may be advantageous to use a “crude” or “semi-purified” form of the glycine betaine ester. As used herein the term “crude” in reference to the glycine betaine ester is understood to mean the reaction product as formed from the reaction of glycine betaine with an aliphatic alcohol in the presence of an acid (typically methanesulfonic acid), i.e., the final reaction product as is, and used without further treatment or purification. The terms “semi-pure” or “semi-purified” in reference to the glycine betaine ester are understood to mean that the reaction product formed is partly purified, i.e., residual glycine betaine and/or aliphatic alcohol are at least partially removed to provide a mixture which is still not a pure sample of the glycine betaine ester. Such “crude” or “semi-purified” glycine betaine ester components may be especially useful as surfactants in the present cleaning compositions. The “crude” and “semi-purified” glycine betaine ester components employed in the present cleaning compositions typically include at least 50 wt. % and, commonly, at least 60 wt. % of the glycine betaine ester.
In one embodiment, the cleaning compositions may include a mixture of a glycine betaine ester of Formula (I):
Me3N+—CH2—C(O)—O—RX− (I)
wherein R is an aliphatic group having 8 to 22 carbon atoms and X− represents an inorganic or organic anion, and one or more of Me3N+—CH2—CO2H X− (“a glycine betaine salt”), an aliphatic alcohol ROH, where R is as defined, and an acid HX. Typically, X− represents an alkanesulphonate anion, such as a methanesulphonate anion and the acid HX is an alkanesulphonic acid, such as a methanesulphonic acid. As used herein, the term “Glycine Betaine” refers to the zwitterionic compound Me3N+—CH2—CO2H X−, where X− represents a methanesulphonate anion. For example, a “crude” or “semi-purified” glycine betaine amide may include a glycine betaine amide of Formula (I) where R is a lauric group and one of more of methanesulphonic acid, lauric amine (RNH2 where R is a lauric group) and a methanesulphonate salt of lauric amine.
In one aspect, a method for treating a hard surface using the self-adhering cleaning compositions described herein is also provided. The method includes applying a dose of the composition directly on the hard surface to be treated. When water is passed over the self-adhering composition and the hard surface, a portion of the self-adhering composition may be released into the water that flows over the dose. The portion of the self-adhering composition that is released into the flowing water may provide a wet film on at least a portion of the hard surface. For example, the method may be used to treat the inside of a toilet bowl. A dose of the self-adhering composition may be applied directly on an inside surface of the toilet bowl.
Further, one of skill in the art will appreciate that, when used in conjunction with a metered dispenser, the dispenser may provide doses of the composition in any volume and/or size that is suitable for the intended application. Similarly, the shape of the dispenser may be any shape that is desired. For example, in an exemplary embodiment, a dispenser used to dispense the present gel composition may include a cylindrical body with the gel contained therein. Such a dispenser may include a guide member to push the gel composition through a dispenser mouth, which may be in any shape that is desirable for the intended purpose. Nonlimiting examples of cross-sectional shapes may be selected from: squares, circles, triangles, ovals, stars, ring-shaped, and the like.
In use, some of the compositions of the present technology may be applied directly on the hard surface to be treated, e.g. cleaned, such as a toilet bowl, shower or bath enclosure, drain, window, or the like, and self-adheres thereto, commonly through a plurality of flows of water passing over the self-adhering composition and surface, e.g. flushes, showers, rinses or the like. Each time water flows over the composition, a portion of the composition is released into the water that flows over the composition. The portion of the composition released onto the water covered surface provides a continuous wet film to the surface to in turn provide for immediate and long term cleaning and/or disinfecting and/or fragrancing or other surface treatment depending on the active agent(s) present in the composition. It is thought that the composition, and thus the active agents of the composition, may spread out from or are delivered from the initial composition placement in direct contact with the surface to coat continuously an extended area on the surface. Typically, the wet film acts as a coating and emanates from the self-adhering composition in all directions, i.e., 360 degrees, from the composition, which includes in a direction against the flow of the rinse water. Motions of the surface of a liquid are coupled with those of the subsurface fluid or fluids, so that movements of the liquid may produce stresses in the surface and vice versa. The composition may be especially useful in treating the surface of a toilet bowl since it allows for delivery and retention of a desired active agent on a surface above the water line in the bowl as well as below the water line.
In one aspect, the composition may be a composition for treating a hard surface that includes (a) an adhesion promoter, which comprises at least one compound including one or more polyalkoxy groups; (b) a glycine betaine ester of formula (I):
Me3N+—CH2—C(O)—O—RX− (I)
wherein R is an aliphatic group having 8 to 22 carbon atoms; and X− represents an inorganic or organic anion; and (c) water; wherein the composition is self-adhering upon application to a hard surface. In some embodiments, the composition may include at least about 25 wt. % water or more preferably at least about 40 wt. % water.

Often, aliphatic alcohol may be present as an unreacted starting material of the reaction used to produce the glycine betaine ester. In such cases, the “R group” of the aliphatic alcohol is commonly the same as the “R group” of the glycine betaine ester. The weight ratio of the glycine betaine ester to the aliphatic alcohol in the compositions may be about 20:1 to 1:5, more commonly about 10:1 to 2:1. In some embodiments, the weight ratio of the glycine betaine ester to the aliphatic alcohol may be about 10:1 to 1:2 or about 5:1 to 1:2.

As used herein, “composition” refers to any solid, gel, and/or paste substance having more than one component.
As used herein, “self-adhering” or “self-adhesive” refers to the ability of a composition to stick onto a hard surface without the need for a separate adhesive or other support device. In one embodiment, a self-adhering composition does not leave any residue or other substance (i.e., additional adhesive) once the composition is used up.
As used herein, “gel” refers to a disordered solid composed of a liquid with a network of interacting particles or polymers which has a non-zero yield stress.
As used herein, “fragrance” refers to any perfume, odor-eliminator, odor masking agent, the like, and combinations thereof. In some embodiments, a fragrance is any substance which may have an effect on a consumer, or user's, olfactory senses.
As used herein, “wt. %” refers to the weight percentage of an ingredient in the total formula. For example, an off-the-shelf commercial composition of Formula X may only contain 70% active ingredient X. Thus, 10 g of the off-the-shelf composition only contains 7 g of X. If 10 g of the off-the-shelf composition is added to 90 g of other ingredients, the wt. % of X in the final formula is thus only 7%.
As used herein, “hard surface” refers to any porous and/or non-porous surface. In one embodiment, a hard surface may be selected from the group consisting of: ceramic, glass, metal, polymer, stone, and combinations thereof. For the purposes of this application, a hard surface does not include silicon wafers and/or other semiconductor substrate materials. Nonlimiting examples of ceramic surfaces include: toilet bowl, sink, shower, tile, the like, and combinations thereof. A non-limiting example of a glass surfaces includes: window and the like. Nonlimiting examples of metal surfaces include: drain pipe, sink, the like. Nonlimiting examples of a polymeric surface includes: PVC piping, fiberglass, acrylic, Corian®, the like. A non-limiting example of a stone hard surface includes: granite, marble, and the like.
A hard surface may be any shape, size, or have any orientation that is suitable for its desired purpose. In one non-limiting example, a hard surface may be oriented in a vertical configuration. In another non-limiting example, a hard surface may be the surface of a curved surface, such as a ceramic toilet bowl. In yet another non-limiting example, a hard surface may be the inside of a pipe, which has vertical and horizontal elements, and also may have curved elements. It is thought that the shape, size and/or orientation of the hard surface will not affect the compositions of the present invention, because of the unexpectedly strong transport properties of the compositions under the conditions described infra.
As used herein, “surfactant” refers to any agent that lowers the surface tension of a liquid, for example water. Exemplary surfactants which may be suitable for use with the present invention are described infra. In one embodiment, surfactants may be selected from the group consisting of anionic, non-ionic, cationic, amphoteric, zwitterionic, and combinations thereof.
As used herein, “gel melt temperature” (“gel point”) refers to the temperature at which the rigid gel composition abruptly transitions to a low viscosity flowable fluid having a viscosity of less than 5 Pa as the temperature of the gel is raised. To measure the gel melt temperature as defined herein a Brookfield temperature controlled Cone/Plate Viscometer (Brookfield Engineering Laboratories, Inc., Middleboro, Mass.) was used according to the manufacturer's specifications. The specific parameters used on the device are: Constant shear rate of 1/sec; C-25-1 Cone; 20° C. to 80° C. temperature ramp-up over 240 seconds.
As used herein, “gel hardness” refers to the hardness strength of a composition. The gel hardness values are determined by measurement at 22° C. using a Brookfield LFRA 1500 Texture Analyzer with TA41 probe (6 mm cylinder diameter, 35 mm length) with a trigger of 5.0 g, penetration distance of 3.0 mm, and a speed of 0.5 mm/sec, recorded as peak load values. In some embodiments, the present compositions may have a gel hardness of at least about 150 g. The compositions may have a gel hardness of at least about 175 g or at least about 185 g. The compositions may have a gel hardness of at least about 200 g. The compositions may have a gel hardness of at least about 250 g. In some embodiments, the gel hardness may range from about 150 g to 300 g. The gel hardness may range from about 175 g to 275 g or more commonly from about 185 g to 265 g. In some embodiments, the gel hardness may range from about 200 g to 250 g.
An assessment of the hardness of a gel can also be made using a Precision Penetrometer, manufactured by Precision Scientific, Co. equipped with a large diameter cone weighing 102.4 grams with a 23D angle and loaded with 150 grams of weigh on the top of a spindle. The hardness is determined by measuring the penetration of the cone into the surface of a polymer or gel solid. Samples must be at least ¼ inch thick to be used with the setup parameters. The measurement is characterized in tenths of a mm penetration into the surface of the solid or gel.
As used herein, “viscosity” refers to the resistance to gradual deformation by shear stress or tensile stress of a composition. The viscosity is measured at 25° C. using a TA AR 2000 rheometer equipped with a 4 cm stainless steel parallel plate and Peltier plate at a shear of 1 reciprocal second.
As used herein, “Force to Actuate” (FTA) refers to the force needed to dispense one dose of sample, i.e., the force required to actuate the product or force to push a dose of the product out of a dispensing device. FTA is measured using an IMADA force gauge, model MF-20, at 25° C. sample temperature. The force gauge is used to dispense one dose of sample. FTA should desirably be about 7-14 pounds of pressure. The dose weight is between 6-8 g with an average weight of dose of approximately 6.6 g.
As used herein, “adhesion” refers to the ability of a dose of gel to remain adhered on a vertical board with a tile surface. “Adhesion time” and “adhesion (in %)” may be measured according to the following protocol. A board containing twelve 4.25″×4.25″ standard grade glossy ceramic tiles arranged in a 3 (in the y-direction) by 4 (in the x-direction) configuration bonded and grouted to a plexi-glass back is provided. Before each determination, the board is rinsed with warm (about 75 to a 85° F.) tap water using a cellulose sponge. The board is then re-rinsed thoroughly with warm tap water. A non-linting cloth saturated with isopropanol is then used to wipe down the entire tile board. The board is placed in a horizontal position (i.e., such that the plane of the board is flat on the floor or lab bench). A force gauge is used to dispense doses of gel on the board. Samples approximately 1.5″ in diameter and weighing from about 5.5 g to about 8.0 g are provided to the surface of the board such that the bottom of the dispensed sample of gel touches the top-most, horizontally oriented (i.e., in the x-direction), grout line of the board. Samples are placed approximately 2″ spaced apart from each other. A permanent marker is used to draw a straight line (parallel to the x-direction) approximately 0.75″ below the top-most grout line. The board is then placed in a vertical position (i.e., such that the plane of the board is perpendicular with the floor or lab bench) in an environmental chamber. The chamber is maintained at a temperature of about 86 to a 90° F. and relative humidity of about 40% to 60%. High and low temperature and humidity is recorded for a determination. The position of gels are checked every 24 hours until all samples have crossed the “fail line” or after specified time has elapsed. A camera is used to record pictures of the samples at time zero and at successive times. The time required for each sample to slide down the tile a distance of 1.5 times the diameter of the sample (circa 2.25″) is determined and recorded as the “adhesion time.” The reported “adhesion time” is an average determined from the values measured samples deposited on three boards. The “adhesion” reported in percentage for a particular sample is the difference above or below the value determined for a control sample.
