ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a fabric protectant that has a plant oil as an active ingredient.
BACKGROUND OF THE INVENTION
A fabric protectant is usually deployed to keep treated fabric unencumbered from certain damages. One of the damages a fabric material may encounter is related to pests. An assortment of pests are known to damage fabrics by means such as feeding upon the fabric material. Clothing may be victim to these fabric-related pests and a fabric protestant against the said fabric-related pests would be an advantage.
SUMMARY OF THE INVENTION
The objective of the present invention is to serve a fabric protectant that efficaciously controls fabric-related pests. The plant oils of horseradish oil, bay oil, basil oil, calamus oil, ginger oil, palmarosa oil, cinnamon oil, ylang-ylang oil, perilla oil, valerian oil, clove bud oil, star anise oil, milfoil oil and fennel oil surprisingly control fabric-related pests efficaciously and, therefore, are utilized to produce the fabric protectant of the present invention.
DETAILED DESCRIPTION OF THE INVENTION
The fabric protectant of the present invention comprises a specific plant oil. The plant oil utilized in the present invention (hereinafter, the present oil), which is selected from the group consisting of horseradish oil, bay oil, basil oil, calamus oil, ginger oil, palmarosa oil, cinnamon oil, ylang-ylang oil, perilla oil, valerian oil, clove bud oil, star anise oil, milfoil oil and fennel oil, oregeno oil and angelica oil. The plant oils utilized in the present invention are standardly essential oils. Therefore, horseradish oil can be obtained by steam distillation of horseradish (
Cochlearia armoracia
), bay oil can be obtained by steam distillation of bay (
Pimenta racemosa
) leaves, basil oil can be obtained by steam distillation of basils (Ocimum spp.), calamus oil is can be obtained by steam distillation of sweet flag (
Acorus calamus
) rhizomes, ginger oil can be obtained by steam distillation of ginger (
Zingiber officinale
), palmarosa oil can be obtained by steam distillation of rosha grass (
Cymbopogon martinii
), cinnamon oil can be obtained by steam distillation of cassia or cinnamon (Cinnamomum spp.) trees, scrubs, barks or leaves, ylang-ylang oil can be obtained by steam distillation of ylang-ylang (
Cananga odorata
) flowers, perilla oil can be obtained by steam distillation of Perilla spp. leaves, flowers or seeds, valerian oil can be obtained by steam distillation of garden heliotrope (
Valeriana officinalis
) rhizomes, clove oil can be obtained by steam distillation of clove (
Eugenia caryophyllata
) buds, stems or leaves, star anise oil can be obtained by steam distillation of star anise (
Illicium verum
) fruits or leaves, milfoil oil can be obtained by steam distillation of milfoil (
Achillea millefolium
), fennel oil can be obtained by steam distillation of wild marjoram (
Origanum vulgare
) and angelica oil can be obtained by steam distillation of Angelica spp. Each present oil may be extracted from the botanical source according to the methods disclosed in
Kouryou Kagaku Souran
(Okuda; Hirokawa shoten publication, 1967). It is also possible to purchase plant oils from the market.
The fabric protectant sets forth efficacious activity against fabric-related pests which mainly damage fabrics. Examples or fabric related pests include Tinea such as case-bearing clothes moth (
tinea translucens
) and casemaking clothes moth (
Tinea pellionella
), Tineola such as common clothes moth and webbing clothes moth (
Tineola bisselliella
), Attagenus such as black carpet beetle (
Attagenus unicolor japonicus
) and
Attagenus unicolor
, Anthrenus such as varied carpe beetle (
Anthrenus verbasci
), Hofmannophila such as brown house mouth (
Hofmannophilia pseudospretella
), Endrosis such as white-shouldered house moth (
Endrosis sarcitrella
), and Dermestes such as hide beetle (
Dermestes maculatus
), larder beetle (
Dermestes lardarius
),
Dermestes haemorrhoidalis
and
Dermestes perunvinus.
Formulations of the fabric protectant may comprise of carriers, in addition to the present oils, but a formulation solely comprising one or more of the present oils is also effective. Cream formulations and liquid formulations such as an aerosol, are examples of formulations that comprise a carrier. A formulation comprising resins usually comprises synthetic resins that were previously impregnated with any present oil. Furthermore, a gel formulation and formulation comprising of paper or bisques wherein the paper or bisque is previously impregnated with any present oil, are also possible formulations of the fabric protectant. Dissolving the plant oil or oils in a appropriate solvent, such as acetone, is a suitable means to impregnate the paper in formulating the formulation comprising an impregnated paper. The fabric protectant usually utilizes formulations comprising the carrier.
Suitable carriers for the liquid formulation include water; alcohols such as methanol, ethanol, glycerin and polyethylene glycol, ethers such as tetrahydrofuran and dioxane; aliphatic hydrocarbons such as hexane, kerosene, paraffin and petroleum benzine; or esters such as ethyl acetate.
Suitable carriers for the cream formulation include hydrocarbons such as liquid paraffin, vaseline and solid paraffin; silicones such as dimethylsiloxane, colloidal silica and bentonite; alcohols such as ethanol, stearyl alcohol, lauric alcohol, polyethylene glycol, glycerin; carboxylic acids such as lauric acid and stearic acid; bees wax; and esters such as lanolin.
The formulations comprising a carrier, such as the liquid formulation and cream formulation, may also additionally comprise auxiliary agents such as emulsifiers, spreading/wetting agents, suspensible agents, preservatives and propellants, or coating agents. More specifically, examples of emulsifiers include soaps, polyoxyethylene fatty acid alcohol ethers such as polyoxyethylene oleyl ether, polyoxyethylenealkyl aryl ethers such as polyoxyethylenenonyl phenyl ether, polyoxyethylene fatty acid esters, fatty acid glycerides, sorbitan fatty acid esters, higher alcohols sulfates and alkylarylsulfonic acid salts such as sodium dodecylbenzenesulfonate;
spreading/wetting agents include glycerin and polyethylene glycol;
suspensible agents include casein, gelatin, alginic acid, carboxymethylcellulose, gum arabic, hydroxypropylcellulose and bentonite;
perservatives include methyl p-hydroxybenzoate, ethyl p-hydroxybenzoate, isopropyl p-hydroxybenzoate and butyl p-hydroxybenzoate;
propellents include dimethyl ether, chlorofluorocarbons and carbon dioxide;
and coating agents include nitrocellulose, acetylcellulose, acetylbutylcellulose, methylcellulose derivatives, polyvinyl alcohols and vinyl resins such as vinyl acetate resins.
Examples of synthetic resins for the formulation comprising resins (hereinafter, resin formulation) include polyethylene; polypropylene; a copolymer composition of ethylene and a monomer that comprises a polar group, such as an ethylene-vinylacetate copolymer, ethylene-methyl(meta)acrylate copolymer, ethylene-ethylacrylate copolymer and ethylene-vinylacetate-methyl(meta)acrylate copolymer; and synthetic resins comprising chlorine atom(s), such as polyvinylchloride and polyvinylidenechloride. The ethylene-vinylacetate copolymer and ethylene-methyl(meta)acrylate copolymer are the preferable synthetic resins, because ethylene-vinylacetate copolymer and ethylene-methyl(meta)acrylate exceed in moldability under a relatively low heat condition, as well as the ability to retain, diffuse, and stabilize the plant oils.
The synthetic resins may comprise the plant oils by means of impregnating the essential oil to the said resin. Methods of impregnation include, the present oil itself impregnating the synthetic resin, dissolving the present oil in an appropriate solution such as acetone and then impregnating the synthetic resin with the obtained solution, or a method wherein a concentrated master pellet is formed.
In the master pellet method, one or more of the present oils
