In comparison, the beeswing, chaff and pith portions of the corncob are much lighter weight and much more adsorbent than is the woody ring portion of the corncob. A typical quantitative analysis is as follows:

(10) In one embodiment, the composition of matter of the present invention consists of two basic elements: first, a carrier characterized by its great capacity for odor and malodor absorption, and gradual release of other active substances toward the air or to its surroundings. Second, one or more chemical, natural or synthetic elements that added to the carrier complete diverse functions, according to the desired results (perfume surrounding air, react with undesirable substances present in the air, liberate therapeutic, repellent, biocide or attractant chemical agents).

(11) The carrier which is the preferred embodiment of the product in the present invention is a material obtained from the threshed ear of corn (Zea maiz) whose special physical and chemical qualities al low the previously described functions, of absorption and gradual release. To obtain the different components that comprise the threshed ear of corn, an industrial process, well known in the state of the art is required, which consists of separation, classification and sizing of each one of the components that constitute corncobs.

(12) The threshed ear of the corn, also known as “olote” in Mexico, “spiga de maiz” in Castilian, corncob in English, “sabugo” in Portuguese and “balle de mats” in French, if cut transversely is constituted by three concentric ring. Starting with the inner ring, they are known in English as pith, woody ring and chaff. The material of the present invention uses the woody ring, chaff, bees wing or fine chaff and pith portions.

(13) The woody ring, as well as the chaff portions have similar characteristics, both can be used as carriers for active ingredients as described in the body of the present invention. The main differences reside in the difference of absorption capacity and in the particle hardness. Other differences exist and are described below.

(14) In order for the woody ring to comply with the requirements of the present invention it must have the following characteristics: woody ring should be about 99% free of other cob particles, it should have no more than about 1% dust or fines (the product should be air washed). It must be subjected to heat treatment that guarantees microbiology content and moisture levels under about 13%. For correct functionality, the particle size should be uniform in size and ranges should not exceed a maximum of about 2380 microns and a minimum of about 250 microns.

(15) The woody ring of corncobs is characterized by the following: a hardness of about 4.5 on the Mohs scale, a fast absorbency of oil (for example soybean oil) of one-to-one on weight basis and the typical molecular structure of a natural fiber. Ideally particle sizing for the present invention should be between the following ranges: 1) retained or larger than a mesh of about 2380 microns, 2) particles between about 2380 and about 1191 microns, 3) particles between about 1191 and about 841 microns, 4) particles between about 841 and about 420 microns.

(16) The main characteristic of the particle size is the contact surface that each one represents; for example, particles between about 1410 and about 841 microns have an average contact surface of about 5.88 square meters per gram. Particles between about 841 and about 420 microns have an average contact surface of about 7.20 square meters per gram. This characteristic is decisive in the qualities of absorption of different substances on the part of the carrier that embodies the product object of the present invention.

(17) It is necessary to highlight that woody ring particles are characterized by having a structure that seen on an electron microscope, resembles that of a sea sponge. One can infer that this type structure has capacity to admit and retain substances of small and large molecular size. This allows superior qualities of absorption in comparison to other products such as Ciclodextrines that as is known in the state of the art, only admits malodor molecules of small size.

(18) The separate and classified sizes of woody ring have unique qualities for the absorption of scents from the air in contact with them. To illustrate this, diverse laboratory tests were made with surprising results as follows:

Example #1

(19) A 100 gram portion of mature Camembert cheese, a 20 gram portion of bacon and a 10 cm dish containing about 25 grams of woody ring particles sized between about 1410 and about 841 microns where all placed in a sealed glass container. Another glass container with the same components except for the woody ring particles was also prepared as a control sample. Both glass containers were inspected at intervals of 24 hours, 3 days, 5 days and 8 days; the container with the adsorbent material practically didn't manifest the characteristic scent of the decomposition of products contained, while the control glass container presented potent and unpleasant scents.

Example #2

(20) 10 grams of tobacco where incinerated in two sealed glass containers. One of the containers had a 10 cm diameter dish containing 10 grams of woody ring, sized between about 1410 and about 841 microns. The other container remained as a control sample. After 24 hours both containers where opened. The container with the adsorbent woody ring particles did not present the characteristic scent of tobacco, while the control sample presented potent scents characteristic of tobacco smoke.

(21) In both examples, the evaluation of the scents or aromas were carried out by the authors of the present invention, as well as by a professional perfumist whose educated sense of the smell surrendered an objective opinion of these examples.

(22) The characteristics of the Chaff portion of the corncob are similar to the woody ring portion in its ability to function as a carrier for fragrances and other active ingredients. The most distinguishing differences are: 1) more absorption; between 1.5 and 3 times it's weight in oil. 2) Particles size between about 841 and about 73 microns and 3) less particle flowability. Woody ring particles are rounder in shape than chaff and therefore flow better.

(23) This physical difference between woody ring particles and chaff particles is translated into functional differences in the ability to adsorb undesirable scents from the air. Additionally, the granular form of the woody ring allows for more interparticle space for airflow. While the smaller closer chaff particles allow less airflow.

(24) Both woody ring and chaff are characterized by having an almost neutral pH, in the order of about 6. This quality makes it an ideal inert carrier with all type of substances, since it does not react with active ingredients. Some other types of carriers have to be deactivated first to neutralize their pH content.

(25) The physical and chemical characteristics of corncobs are not favorable for the development of microorganisms, therefore not providing fertile ground for bacteria or fungi that in turn cause malodor or disagreeable scents. It is known in the state of the art that a whole corncob can be stored without cover for periods of one year.

(26) The functional differences of the woody ring portion (flowability and larger interparticle space) and that of the chaff (more absorption) allow for a great diversity of applications and use. These corncob fractions can be used combined or separately, for different applications, that are described for the adsorbent carrier that integrates the product object of the present invention.

(27) For example, if the functional objective, is the absorption of an active substance to be slowly released in the air and at the same time allowing the flow of malodor air to be adsorbed, the suitable product is the one obtained from the woody ring. If on the contrary the functional object is to achieve absorption of an active substance to be slowly released in the air and the absorption of malodors or scents is not important, the elected product would be the chaff portion.

(28) Other approaches to select the corncob fraction can be: the convenience of not having powders or fines. An example of such an application is the integration of the adsorbent agent to active filtration systems where the use of the product from the woody ring is most suitable. If the active ingredient required is thick in nature or if product were required to be molded in a three-dimensional object (including the making of pellets), one would be inclined to select the chaff portion.

(29) On the other hand, and a substantial element of the composition of matter, object of the present invention, are the active substances or ingredients to be used. These can be aromas, perfumes, flavors or other natural or chemical agents that are integrated to the product derived from the composition of matter object of the present invention. In general, these substances are available in a liquid, powder or granular state and depending on the active agents chemical constitution, soluble in oil or water.

(30) Under these conditions the adsorbent carrier, depending on the type of active ingredients used, can adsorb a larger or smaller quantity of said agent. This depends primarily on the size of the active ingredient molecule size, the adsorbent carriers gradual release will also depend on this molecular size. The absorption of malodor or scents is simultaneously achieved. The intensity, duration and brightness of the aroma, with fragrances, will depend on factors of the active ingredient or agent's composition. For example, larger molecular size is equal to longer duration, while the presence of smaller molecular sizes such as those in an ester, evaporate quickly.

(31) Some examples for the formulation of the adsorbent carrier with active substances in a liquid state are:

Example #1

(32) For fragrances, perfumes and therapeutic aromas, generally using a base of polyvinyl glycol, light mineral oil or microencapsulated powder or granular base, the concentration on a weight basis of the woody ring to active ingredient, is from about 0.01% to about 18%. A larger amount saturates the adsorbent carrier and product flowability is greatly reduced. For concentrations on a weight basis of the chaff portion ranges from about 0.01% to about 36% are required.

Example #2

(33) For repellents and attractants, generally in oleaginous or microencapsulated powder or granular bases such as Givaudans Flavor Burst™ products, the recommended concentration ranges, for the woody ring as well as the chaff portion, are similar to the previous example. Concentrations depend on the active ingredient or agent used and the functionality desired in the end product.

Example #3

(34) For oxidizers and chemical reducers or neutralizers, generally in a liquid or solid microencapsulated powder or granular base, the concentration ranges on a per weight basis, both for woody ring and chaff are from about 0.05% to about 5% of active ingredient or substance. Being that the determinant factor is not the capacity of carrier absorption, but rather the capacity to stay stable and not be affected by the active substance.

Example #4

(35) For antibacterial and fungicidal use, when these are in a water, oleaginous or microencapsulated powder or granular base, the proportion of active ingredient or agent on a per weight basis to adsorbent carrier is the same as that of example #1. When the active ingredient uses a water base, the concentrations on a per weight basis can range from about 0.01% to about 25% with the woody ring fraction and about 0.01% to about 50% with chaff. The concentration to choose will be determined by the experience of whom ever prepares formulations according to the known state of the art.

(36) Additionally, as mentioned in previous examples, the formulation of the composition of matter or product object of the invention, can be made using liquid based active ingredients added to the adsorbent carrier. The possibility also exists for the use of solid materials as active ingredients, usually in the form of pure or microencapsulated products. This variation allows more flexibility in the adsorbent carriers' applications. It can also take advantage of factors like stronger concentrations of active ingredients. Many pure substances come in solid form; the use of a liquid as diluent or dispersant of the pure substance implies a reduction in its concentration or strength. For example, table salt NaCl is more intense to the palate than its version diluted in water, commonly called brine.

(37) On the other hand, the use of active ingredients in solid state can adhere and/or adsorb to the surface of the adsorbent corn cob carrier, allowing it to use a larger proportion of its inner adsorbent capacity for malodor or other applications. The opposite occurs when using active ingredients in a liquid state, since these occupy more of the corncob carriers' odor adsorbent capacity thus partially reducing its ability to adsorb undesirable malodor.

(38) The option of using active ingredients in solid state instead of liquid, is possible with the concurrence of 4 basic elements: an adsorbent carrier, constituted by a fraction derived from corncobs, an active ingredient or agent that is in liquid or solid state; a combination resulting from the mix of a mineral or organic carrier with a liquid base active ingredient and finally, a substance that assures that, the active ingredients adsorb or absorb to the corncob carrier (avoiding the separation among carriers or agents and assuring correct homogeneity, functionality and dispersion).

(39) To exemplify the above-mentioned, we describe two practical examples. The results obtained, using two types of active ingredients one in liquid form and the other solid, both dispersed in the corncob carrier; woody ring sized between about 1410 and about 841 microns was used. The liquid active ingredient is a concentrated floral fragrance perfume using polyvinyl glycol as a carrier.

Example #5

(40) Corncob carrier mixed with an active ingredient in is a liquid base.

(41) The density of the active ingredient determined a saturation point of about 18% on a per weight basis to the corncob granules. 180 grams of active ingredient where mixed with a kilogram of corncob carrier. This proportion maintains carrier flowability, absorption of odors and slow release of active ingredient (fragrance).

(42) Results: the perfuming active ingredient, was released gradually and perceived smell lasted 30 days. The corncob carrier continued adsorbing scents in the air after 30 days.

Example #6

(43) Two active ingredients; one utilizing an encapsulated active ingredient, commercially available, like Givaudan fragrance or flavor, in powder form and the other, using a laboratory sample, made by mixing Silicon Dioxide (SiO2), in proportion of 1 to 4 on the base of liquid active ingredient to Silicon Dioxide weight. The adsorbent corncob carrier was impregnated with an adherent coating, in this case consisting of about 0.5% per weight basis, foamed solution of anionic surfactant with water. Once the corncob carrier was mixed with the foam, an adherent coating of foam formed on the corncob granules. Immediately after which the active ingredients in solid form where added. The active ingredient particles adhered to the coating and allowed for a homogeneous mixture without separation.

(44) Results: In both cases the adhesion of solid particles to the corncob granules allowed a more intense and prolonged duration of the perfuming scent, which was slowly released over a 60 day period, in comparison to the 30 days obtained in example #5 with a liquid active ingredient perfume mixed directly with corncob granules. In both cases the corncob adsorbed odors in the air even after 60 days.

(45) Both examples, one with liquid and the other with solid active ingredients were performed at the same time. The new product was exposed to the air by placing it in a 40 cm×5 cm dish. The product was placed in two separate rooms measuring 3×4×2.4 mts.

(46) The adherents used to form a coating on corncob particles are within the following ranges:

Example #7

(47) Using surfactants as adherent coating: anionic, cationic and amphoteric can be used. The formulation is: foam obtained from adding water to about 0.02% to about 5% of surfactant by weight. The quantity of foam on a per weight basis to corncob woody ring fraction (carrier) is between about 0.5% and about 3.5%. Larger proportions do not allow for an appropriate mixture when adding active ingredients in solid form.

Example #8

(48) Using mineral oils as an adherent coating; they should be highly refined preferably odor and colorless; viscosity on the Saybolt scale (SUS/210 F) should be between about 40 and about 300. The concentration of mineral oil by weight to woody ring is between about 0.5% and about 18%.

(49) Finally, active ingredients can be polymers, perfumes, oxidizers, attractants, repellents, reducers, antibacterials, etc. in solid form. These ingredients are mixed and dispersed with the granular corncob carrier sized between about 37 and about 250 microns. The quantity of solid active ingredient dispersed should be between about 1% and about 40% per weight basis.

(50) The examples described above can be characterized by the following:

(51) 1. A carrier formed by particles obtained from one of the woody ring and chaff portion of the corncob;

(52) 2. The particles having less than about 1% of fines by weight;

(53) 3. The particles having a moisture content below about 13%;

(54) 4. An active ingredient mixed with the carrier consisting of polymers, fragrances, perfumes, flavors, oxidizers, attractants, repellents, reducers and antibacterials, in either a liquid or solid state; and

(55) 5. An adherent comprising a surfactant, mineral oil and an organic oil.

(56) Although these examples worked well for adsorbing undesirable odors from the air, it is desirable to provide a carrier that is capable of adsorbing malodors from all three states of matter: 1) gas; 2) liquid and 3) solid. In addition, it would be desirable to provide a carrier comprising a semi-rigid colloidal dispersion of a solid with a liquid or gas, such as a gel, jelly, glue, and the like, that is capable of adsorbing undesirable odors.

(57) It has been discovered that aside from the woody ring and chaff portions of the corncob, other portions of the corncob also adsorb odoriferous substances, namely bees wing and pith portions. In addition, other compositions of matter, such as saw dust, granules or particles from any type of wood, powder, shavings, granules or particles from bamboo powder or flour, milled straw, cellulose, hemicelluloses and lignin adsorbent minerals, silica, zeolite and polysaccharides such as dextrose and starch either individually or mixed, are characterized by its qualities to adsorb scents present in gas, liquid and solid states of matter, while simultaneously serving as a carrier for any active ingredient or combination of active ingredients. Active ingredients are gradually released by the carrier or combination of carriers.

(58) Some examples for the formulation of the adsorbent carrier with active substances in a gas state are:

(62) Mix of corn cob fractions can be milled or ground to obtain different particle sizing-from finest powders to the largest granules obtainable as known in the art-from individual corncob fractions, all of which comprise a mix of celluloses, hemicelluloses and lignin. Particle sizing depends on the desired contact surface area which in turn depends on the application and targeted odors and active ingredients. Particle sizing is measured in the art using U.S. Standard mesh screens sieves.

(63) Particle sizing range for corncob or other described materials pass mesh U.S. Std mesh #3½ (about 5664 microns) and retained on U.S. Std. mesh #635 (about 20 microns).

(65) All corncob fractions comprise cellulose, hemicelluloses and lignin. It has been observed that other sources of cellulose, hemicelluloses and lignin, such as but not limited to: saw dust from wood, bamboo powder or flour etc. provide adsorbency of odoriferous substances and can be used individually or mixed with of corn cob fractions.

(66) Result: It has been determined that lignin from maize/Lignin

(67) Peroxides/Lignin Alkali or Lignin obtained by any other process, when added to corncob fractions and/or different mixes of cellulose, hemicelluloses and lignin containing material, significantly enhances odor adsorbency.

(71) It has been determined that corncob fractions comprise cellulose, hemicelluloses and lignin. It has been observed that other sources of cellulose, hemicelluloses and lignin, such as but not limited to: saw dust from wood, bamboo powder or flour etc. have adsorbency of odoriferous substances and are well suited to adsorb odoriferous substances such as ammonia, trimethylamine, skatole, isovaleric acid, 3 methyl-2-hexinoic acid, 3-mercapto-3-methyl hexanol, dimethyl disulfide, p-Cresol commonly found emanating from human and animal bodily fluids such as feces, urine, sweat and other human or animal bodily malodors. Animal bodily waste malodors such as but not limited to dog and cat feces and urine. Adsorbency of these malodors also apply to present invention, making this composition of matter, suitable but not limited to use in baby diapers, adult diapers, feminine protection pads, portable toilets, latrines cat litters and other applications where human or animal bodily odoriferous substances are present.

(72) Based on the results from the above two Examples, a new composition of matter for use in controlling bodily malodors has been developed and tested with portable toilets, latrines, feminine protection pads, adult diapers and baby diapers. The new composition of matter consists of: Individual corncob fractions or mix of corncob fractions and/or other cellulose, hemicellulose and lignin source. Liquid fragrance or fragrance encapsulated or mixed with materials, such as but not limited to, silica, specialty silicas, synthetic amorphous silica, dextrose, zeolite, silica/aluminum oxide, and the like. Coating of encapsulated fragrance or any active ingredient, with materials such as but not limited to mineral oil, vegetable oil, animal oils, polymers and any other coating material, known in the art to coat and control the release of encapsulated fragrance or active ingredients. Other additives may be utilized, depending on objectives sought, such as PH buffering, surfactants and dispersants, hence light acids, solvents, such as dipropylene glycol, isopropyl myristate and benzyl benzoate or a light mineral oil may be added.

(73) The new composition of matter can be in powder form or any form of compressed powder or agglomerate known in the art, such as, but not limited to; pellets, tablets, pads etc. Additionally, powder or compressed forms may be encapsulated or put in a pouch.

(93) In conclusion, the incorporation of corncob fractions mentioned with active ingredients, whether chemically synthesized or natural, improves the qualities and functionality that both elements have for themselves separately. Further, the use of corncob particles from all four parts of the corncob as an adsorbent of odoriferous substances from the environment is also a novel concept. In addition, the carrier can be made from other celluloses and/or their basic chemical composition, cellulose, hemicelloloses, lignin, adsorbent minerals, such as, but not limited to, silica and zeolite, polysaccharides, such as dextrose and starch, either individually or mixed. Examples of the above, but not limited to, are: saw dust, granules or particles from any type of wood, powder, shavings, granules or particles from bamboo powder or flour, milled straw, cellulose, hemicelluloses and lignin adsorbent minerals, silica, zeolite and polysaccharides such as dextrose and starch either individually or mixed. The forms of carrying out the mixture or integration of these elements can vary according to the circumstance. The types of active ingredients that will be used depend on the functional objective that is pursued, equipment available and the experience of those skilled in the art.
