Definitions

  • This invention relates to an abs orbent composition usef u l as an absorbent for aqueous systems, including urine, particularly useful as an improved animal or pet litter composition, and useful as an absorbent for oleophilic materials such as petroleum or vegetable based oils and the like.
  • the invention also relates to a method of making the improved absorbent composition and litter compos itions containing same.
  • the absorbent composition is comprised of clay and a nitrogenous compound absorber, such as cyclodextrin or other agents which form a matrix system or comp lex similar to cyclodextrin.
  • Such other agents include polymerized cyclodextrin and cyclodextrin derivatives and polycarboxylic acid polymers, such as acrylate polymers.
  • Natural grasses such as alfalfa have been employed in the past with a clay for a binder. While such natural grasses may contain some odor suppressant ability as a result of any chlorophyl present therein, alfalfa has a strong odor itself, particularly when wet.
  • Other materials have been tried along with the alfalfa employing grain or grass straw, such as described in U.S. Patent 4,258,660, which employs clay as a binder for maintaining the ingredients in a pelletized form, rather than for its moisture absorptivity property.
  • fragrance releasing additives In order to overcome odor problems, the use of fragrance releasing additives has been suggested as in U.S. patent 3,921,581, which incorporates consolidated particles having the property of fragrance release.
  • the particles are composed of a minor amount of a perfume agent and major amount of a solid excipient of molded, finely divided or powdered solids of a binder and water sensitive disintegrant.
  • the excipient may be all clay or include other finely divided cellulosic solids, such as sawdust, or chlorophyl containing solids, such as ground alfalfa.
  • the binder and water sensitive disintegrant may be water soluble or dispersible gums such as guar gum, microcrystalline cellulose or pregelantinized starch.
  • the fragrance release composition is then blended with a porous expanded litter product prepared from equal parts by weight of ground al fa and gelatinized wheat flour.
  • an animal litter generally is described which is composed of acidic cellulosic materials which include dried grasses or hay, husks, sawdust, corn cob grits, excelsior and cereal hulls.
  • the cellulosic materials are merely ground to a desirable size and sprayed with the acid solution.
  • an improved absorbent composition comprised of a cellulosic component, a binder and cyclodextrin as a nitrogenous compound absorber. This provides an effective animal litter product even without addition of a fragrance although the cyclodextrin is also an effective carrier for any desired added aromatic fragrance.
  • compositions of this invention retain other desired advantages in that low cost materials are employed, which are non-toxic and which have a reduced odor, even when employed without added fragrance.
  • the absorbent composition comprises clay carrying a nitrogenous compound absorber such as cyclodextrin.
  • a nitrogenous compound absorber such as cyclodextrin.
  • This may be prepared by simple admixing of the cyclodextrin and the clay particles.
  • the cyclodextrin will be present either as a surface coating or is incorporated internally into the clay base or substrate dependent on the method of preparation of the product.
  • a liquid dispersion of the cyclodextrin may be applied, i.e , by spraying an aqueous disperson of the cyclodextrin on to the clay particles.
  • an adhesive may be employed in order to ensure adherence of the cyclodextrin to the clay.
  • the clay after mixing, is crushed to an appropriate particle size and coated with a liquid application of an adhesive or binder followed by application of a dry, cyclodextrin powder which adheres to the clay through the adhesive applied.
  • a kiln dried clay is generally employed.
  • the cyclodextrin is added to the resulting clay slurry or mud and the cyclodextrin is incorporated internally into the clay.
  • the clay is mixed in a slurry form containing water sometimes referred to as a "mud.”
  • the cyc lodextrin is added to the mud product at the desired level.
  • the clay slurry or mud containing the cyclodextrin is then dried or baked and subsequently crushed or broken into the appropriate particle size. In this method no adhesive is usually necessary.
  • the invention concerns an absorbent composition particularly adapted for use as an animal litter comprised of clay and a nitrogenous compound absorber such as cyclodextrin or other agents having a matrix system similar to cyclodextrin.
  • a nitrogenous compound absorber such as cyclodextrin or other agents having a matrix system similar to cyclodextrin.
  • the invention also concerns methods of preparing such an absorbent composition.
  • the major component of the absorbent composition of the present invention is clay or clay like materials.
  • Clay as the term is used herein, is intended to encompass the usual aluminosilicate minerals, such as kaolinite, halloysite, attapulgite, montmori llonite, vermiculite hectori te and the like, as well as diatomaceous earth or Fuller's earth.
  • the matrix of the cyclodextrin in combination with the expanding crystal lattice of the clay material such as bentonite powder a particularly desirable and effective absorbent composition.
  • diatomaceous earth and attapulgite are also commonly employed in animal litter and are desirable materials.
  • Diatomaceous earth is generally available commercially as a kiln-dried material resulting from a mined product containing about 20% moisture.
  • MontmoriUonite is generally supplied as a rotary kiln-dried product resulting from a mined product containing about 35 to 40% moisture and is kiln dried commercially to a moisture content of about 8 to 9% .
  • the substantial ly dry clays will contain about 10 to 15% moisture with 10% or less being preferred.
  • Cyclodextrins are the preferred ingredient for control of odor as a nitrogenous compound absorber or selective entrapment agent.
  • the cyclodextrins are cyclic oligosaccharides that contain at least six ⁇ -1,4 linked D glucopyranose units.
  • ⁇ -Cyclodextrin has 7 units, while ⁇ and v have 6 and 8 respectively.
  • Cyclodextrins have the shape of a hollow truncated cone with primary and secondary hydroxy groups crowning opposite ends of the torus. The inside of the molecule provides an ability to admit various guest molecules into the inner cavity. The formation of an inclusion complex with the cyclodextrin will depend on the relative size and ionic nature of the guest molecule. While net wishing to be limited thereto, it is believed that nitrogenous compounds are absorbed as a guest molecule in the inner cavity of the cyclodextrin.
  • cyclodextrin is the preferred material
  • other materials which form a matrix or complex similar to cyclodextrin may be employed in similar manner to act as the nitrogenous compound absorber.
  • Compounds having a matrix, or forming a complex similar to cyclodextrin include cyclodextrin derivatives and various polymers which are inert and non-toxic.
  • cyclodextrin derivatives which may be employed are cyclodextrin carbamates (such as shown in U.S. Patent 3459732) and the cyclodextrin polyol ether or polyethers (such as described in U.S. Patents 3453259 and 3459731).
  • polymers are polymerized ⁇ -cyclodextrin which is available commercially from American Maize. Synthetic or plastic polymers may be employed. Illustrative of these polymers are acrylate polymers such as sold by wickhen Products under the name POLYTRAP R . One such product is POLYTRAP 603. These products are described by the supplier as fully thermoset crosslinked acrylate polymers which are non-toxic and capable of entrapping a fragrance. Some of the copolymers are specifically described as polyglycerol acrylate and polypropyl acrylate. The polymers are generally polycarboxylic polymers consisting of monomer units of acrylic acid or metnacrylic acid. Generally the carboxyl groups are esterified at least in part.
  • alkyl esters i.e. methyl, ethyl, propyl and butyl, and the glycerol esters are preferred.
  • macromolecular compounds which are partially structured of monomer units with a free carboxylic acid group are highly polymerized co-polymerizates of acrylic acid and/or methacrylic acid with acrylic or methacrylic acid esters.
  • the polymerisates may be obtained in powder form as well as an aqueous dispersion.
  • These acrylate co-polymers are capable of carrying more fragrance than cyclodextrin and are accordingly generally employed in a smaller amount. This property is also believed to provide for slow fragrance release where a fragrance is added to the composition.
  • fragrance which does not materially affect the basic litter composition of cellulosic materials and binder, will generally be included in the composition.
  • Fragrances employed are natural or synthetic aromatic volatile compounds generally employed as a fragrance by those skilled in the fragrance art.
  • the nitrogen absorbing compound or ingredient will be employed in an amount of up to about 2% by weight of the total litter composition, however, it is desirable not to exceed about 1%, and generally from 0.05 to about 0.5%, preferably about 0.1% is employed.
  • the cyclodextrin is present at about 0.1% by weight of the clay.
  • the cyclodextrin may carry a 10% fragrance load, which at a 1% level of cyclodextrin would provide about 0.1% fragrance based on total composition.
  • the fragrance level will accordingly be about 0.01% of the total composition, which is the preferred level of fragrance where such is employed.
  • fragrance may load fragrance at a higher level than cyclodextrin.
  • polymer systems may be capable of loading as high as 60% fragrances.
  • the acrylate copolymers noted above are capable of carrying about 6 times more fragrance than cyclodextrin and according ly may be employed in about one-sixth the amount required when cyclodextrin, or a cyclodextrin derivative, is employed. It is however preferred that the fragrance level be maintained at a level of about 0.01% fragrance based on total composition and, accordingly, the amount of such polymer system will be adjusted to provide that level of fragrance.
  • fragrance is carried by the cyclodextrin it may be incorporated into the cyclodextrin before application of the cyclodextrin to the clay.
  • fragrance or essence may be added by simple addition to the cyclodextrin-clay product during the bagging or packaging operation.
  • periodic injections of the fragrance or essence is injected during the packaging operation of the dry litter absorbent composition which consists essentially of the clay and cyclodextrin.
  • a liquid adhesive or binder is first applied to the clay so as to bind or adhere the cyclodextrin to the clay.
  • binders or adhesives may be applied in the form of aqueous solutions or dispersions of the adhesive or binder.
  • aqueous solutions employed will generally be solutions containing from 2.5 to 7% by weight of the adhesive. A 5% solution is generally preferred.
  • the aqueous solution is applied at a rate so as to apply to the clay from about 0.25 to about 0.7% by weight of adhesive based on the clay, with about 0.5% preferred.
  • the clay surface may be merely wetted with water, or other liquid and the cyclodextrin applied. Further a thin or dilute dispersion of a clay itself may be applied and function as a binder for the cyclodextrin.
  • the adhesive or binder include the water soluble or dispersible products such as the vegetable gums like the polygalactomannan gums, i.e. guar gum and locust bean being the most common.
  • the binder may also be an alginate or xanthan gum, a pregelatinze c starch such as pregelatinized cornstarch or microcrystalline cellulose polymers.
  • the clay is the major or principal ingredient of the absorbent composition and accordingly the clay will comprise about 90%, and generally 95% or more by weight of the composition.
  • the clay will accordingly comprise in excess of 99% by weight of the total composition, i.e., about 99.8 to 99.9%.
  • an adhesive or binder is employed the clay will comprise about 99 to 99.5%.
  • Other absorbent materials may be employed in addition to the clay if desired. Such are known to those skilled in the art. When such are employed, however, the clay absorbent should be employed in a major amount not less than 50% by weight of the total absorbent composition.
  • the process of preparing the absorbent composition may generally be described as comprising adding to an absorbent clay a nitrogenous compound absorber such as cyclodextrin in an amount of about 0.05 to 2% by weight, preferrably about 0.1%.
  • the cyclodextrin is applied in the form of a dry powder after application to the clay of an adhesive or binder in liquid form, i.e., an aqueous solution.

  • Method D an aqueous dispersion of the cyclodextrin is sprayed, or otherwise applied to the clay, to provide the amount of cyclodextrin indicated after which the product is dried and packaged.
  • aqueous solutions should not be employed, or should be avoided, when a fragrance is carried by the cyclodextrin as the cyclodextrin may prematurely release the fragrance in the presence of water.
  • other liquids may be employed in the solution or dispersion applications methods.
  • Such other liquids would be glycols or alcohols such as propylene glycol; and glycerin or vegetable oils.
  • the preferred clays are the bentonite or montmoril lonite clays, attapulgite and diatomaceous earth.
