Technical Field

The present invention relates to a composition for odor control and a carpet having long lasting odor control properties.

Background

Odor-reducing products for carpets are highly desirable. Current technology locally applies the desalination product to the fibers either during manufacture or by the consumer as a special case (occasional). These products are directed to carpet fibers which are generally wash durable and therefore washable. However, the malodor trapped in the carpet backing layer persists and continues to produce a lingering odor. Environmental odors heavier than air (such as smoke, cooking odors) are the most noticeable. Most pet owners avoid carpeting because it is nearly impossible to eliminate the urine smell after an accident in their pet. There is limited concern for odor reduction of carpet backings. Some products on the market claim deodorant properties once incorporated into the matrix, but the data suggest that this is not the case.

Current technology works locally as a stand-alone coating material or as a volatile molecule trap (capture) and therefore does not work well when incorporated into a material. Some industry standard techniques that can be incorporated into backing materials lose the ability to control odor once incorporated.

Thus, there is a need for odor control carpets having long lasting odor control properties.

Description of the preferred embodiments

The following description of the embodiments of the present invention is merely exemplary in nature and is in no way intended to limit the invention, its application, or uses. The present invention has a wide range of potential applications and utilities. The following description is provided herein by way of example only, and is not intended to limit the scope or spirit of the invention for the purpose of providing an enabling disclosure of the invention.

In one embodiment of the present invention, a deodorant composition having long-lasting odor control properties is provided. The term "durable" as used herein means a property that cannot be washed away or easily removed in a normal use mode or without a significant amount of washing. The deodorant composition comprises at least one compound containing an aromatic group and exhibiting acidity. The deodorant composition further comprises a carrier such as water or an oil-based carrier such as an organic ester or glycol; and optionally a compatibilizing agent.

Classes of compounds that contain an aryl group and exhibit acidity include, but are not limited to: (1) aromatic compounds containing, as a part of their structure, carboxylic acids (such as oleic acid, stearic acid, cinnamic acid, salicylic acid), high molecular acids (polymers having an acid group such as polyacrylic acid, polylactic acid), sulfonic acids, or phenol groups, and anhydrides and esters of these compounds having Lewis (Lewis) acid properties; (2) naturally derived heterocycles, such as purine and pyrimidine based structures, including uric acid; (3) derivatives of pyridine, such as pyridine-2-thione N-oxide, and inorganic salts and complexes of substituted pyridines; (4) heterocycles such as furan, 4H-pyran, pyrrole, imidazole, pyrazole, triazole, pyrimidine, pyridazine, pyrazine, thiophene, oxazole and thiazole, and derivatives of these compounds, as well as inorganic salts and complexes of substituted heterocycles.

With respect to class (1), examples of aromatic species containing as part of their structure a carboxylic acid, polymeric acid, sulfonic acid, or phenolic group, as well as esters and anhydrides of these compounds include, but are not limited to: (1) benzoic acid and related saturated or unsaturated acids of the same series, such as 2-phenylacetic acid, cinnamic acid, phenylpropionic acid, and substituted forms of this group of acids, utilizing substituents to alter pKa, solubility or hydrophobicity; (2) benzenesulfonic acid and substituted benzenesulfonic acids, utilizing substituents to alter pKa, solubility or hydrophobicity; (3) phenylboronic acid and substituted phenylboronic acids, the substituents being utilized to alter pKa, solubility, or hydrophobicity; (4) phenols and substituted phenols, with substituents to alter pKa, solubility or hydrophobicity; (5) phenylphosphonic acid and substituted phenylphosphonic acids, with substituents to alter pKa, solubility or hydrophobicity; (6) heterocyclic acids, such as picolinic acid and nicotinic acid, and substituted heterocyclic acids, utilizing substituents to alter pKa, solubility, or hydrophobicity; (7) phthalic acid and isomers of phthalic acid, such as isophthalic acid and terephthalic acid, and substituted forms of phthalic acid and its isomers, with substituents to alter pKa, solubility, or hydrophobicity; (8) naphthoic acids, isomers of naphthoic acids, and substituted naphthoic acids, with substituents to alter pKa, solubility, or hydrophobicity; (9) naphthalenesulfonic acids, isomers of naphthalenesulfonic acids, and substituted naphthalenesulfonic acids, utilizing substituents to alter pKa, solubility, or hydrophobicity; (10) polystyrene carboxylates or sulfonates, or copolymers containing these groups. Such substitutions are readily apparent to those of ordinary skill in the art without undue experimentation.

Gallic acid and its derivatives are non-limiting examples of benzoic acid or phenol substituted under classes (1) and (4). Sulfobenzoic acid and its derivatives are non-limiting examples under class (2). Sulfophthalic acid and its derivatives are non-limiting examples under class (7). Phosphonic acids and derivatives thereof are non-limiting examples under class (5). Derivatives are included in each category as "substituents".

Compatibilizers are chemical agents used to prevent the deodorant compound from interacting with the latex. Whether a compatibilizing agent is used may depend on the latex formulation. If the latex has a pH of <7, a compatibilizing agent is generally not required. If the pH of the latex is >7, a compatibilizing agent is generally required. Where the "acid" is water insoluble or poorly water soluble, the low water solubility results in a low dissociation rate when introduced into the water-based latex, thus reducing the effect of the "acid" on the pH of the system. In the case where the "acid" is more soluble in water, the dissociation rate is high at the latex system pH, which can result in significant changes in latex pH.

There are several non-limiting examples of compatibilizing agents and compatibilizing methods, including but not limited to: using buffers such as monopotassium phosphate or N-cyclohexyl-2-aminoethanesulfonic acid; the use of conjugate bases of carboxylic, sulfonic or other organic acids, such as sodium lauryl sulfate, and/or organic esters of such acids; and in particular the encapsulation of the "acid" in the polymer shell.

Other additives may be present in the deodorant composition, including but not limited to: dispersants such as hydrocolloids; thickeners such as fumed silica, polyacrylates, and polyethyl acrylates.

The deodorant composition may be in the form of a powder or a liquid. However, liquid delivery systems may be preferred to achieve good mixing between the latex and the deodorant composition.

In one embodiment of the present invention, the deodorant composition is combined or mixed with a latex to form a deodorant latex composition. Latex is a dispersion of polymer particles in water. Depending on the end use, fillers, surfactants, thickeners, pigments, stabilizers and other additives are other possible ingredients in the latex. The deodorant composition is compatible with a variety of water-based latexes and can be used in any application where a latex is used.

In one embodiment of the present invention, the deodorant latex composition is preferably incorporated into the backing material of the carpet during the carpet manufacturing process.

The deodorant composition of the present invention can be used as an additional additive (add-on) in various water-based formulations. Thus, the deodorant composition does not require a separate process or change of surface properties of the article. In addition, the latex provides a medium in which the aromatic groups can be oriented, thereby creating a surface for molecular interaction of aromatic compounds, nonpolar and basic molecules, and odor capture. Because latex-like materials absorb odors, such deodorant compositions provide a solution for embedding in latex materials that is more efficient and better than current technology in terms of its odor adsorption capacity and the range of chemical classes of odorants that the deodorant composition can adsorb.

In one embodiment of the present invention, a method of making a deodorant composition is provided. The method includes combining a compound that contains an aryl group and exhibits acidity, an optional compatibilizing agent, and a carrier such as water.

In one embodiment of the present invention, a method of making a deodorant latex composition is provided. The method includes combining or mixing a deodorant composition with a latex to form a deodorant latex composition.

In one embodiment of the present invention, a method of using a deodorant latex composition is provided. The method includes applying the deodorant latex composition as a secondary backing to the backing material of the carpet.

In one embodiment of the present invention, a carpet having a deodorant composition therein is provided.
