Textile deodorant composition {DEODORANT COMPOSITION FOR TEXTILES OR FABRIC}

[Industrial use]

The present invention is a novel garment characterized in that it essentially contains an inorganic metal complex compound having excellent initial deodorizing power for the purpose of deodorizing odorous substances soaked or contaminated with various fibers without damage to the fibers, such as dyeing or discoloration, and A fiber deodorant composition for use in textile products.

[Prior art]

Generally, odor deodorizing products used to remove unpleasant odors in homes are fragrance products or air products whose main fragrance is fragrance to remove odorous substances that cause unpleasant sensations for comfort and cleanliness in indoors and outdoors. As a freshener product and a product for removing bacteria and mold odors, it has been used for a long time, and recently, there is a trend of increasing interest in deodorant products for such a living environment. Recently, however, there has been a recent interest in deodorizing products for clothing and textile products that can easily remove the unpleasant odors caused by odors or stains that are easily combined with clothing or textile products in life and do not damage them. The situation is rising.

Easily fold or contaminated clothing or textile products around the daily life is the basic odor of nitrogen compounds such as ammonia and amines, such as a smell of sweat, body, toilet, smell of meat or fish, and the smell of kimchi vegetables Acidic odors of sulfide compounds such as hydrogen sulfide and mecaptans, and volatile odors such as tobacco odors, which are generated from bacteria and mold odors, are known as major odor sources causing unpleasant odors. It is true that people who are susceptible to bad smells or contaminated with a bad smell because they are easily exposed to textiles such as clothes, curtains and carpets, also complain of severe discomfort.

These odors can also cause unpleasant odors, such as curtains, sofas, carpets, and even beds or wardrobes, especially when cooking in a kitchen in a closed living area, or when stored and left unventilated for a long time. In addition, even bacteria and fungi multiply in clothing and textile products, which can cause unpleasant odors and cause skin irritation and various skin diseases, which can cause hygiene.

On the other hand, in our daily lives, the detection of odors is a result of several chemical and physical reactions that reach the olfactory organs. As a result, volatiles are absorbed by the epithelial cells of the olfactory epithelium, causing changes. It is transmitted to the brain to detect odors. Recently, as awareness of the comfort of living spaces is gradually increasing, odor is one of the elements that constitute environmental sources, and as interest in sources of unpleasant odors grows, in many countries, regulatory laws such as the odor prevention law or the air pollution prevention law The government is enacting strict regulations.

Such odorous substances that cause severe discomfort in living spaces are variously expanded to include odors of living as well as biological excreta, debris, and various industrial wastes and wastewater. These compounds are known as odorous substances that are easily encountered in everyday life such as amine compounds such as basic ammonia and trimethylamine, sulfide compounds such as acidic hydrogen sulfide and methylmecaptan, and aldehyde compounds such as acetaldehyde having low volatile points. Various methods have been used in the past for the purpose of removing such odorous substances.

1) Chemical Removal

A method of radically removing odorous substances by reacting substances with strong reactivity to odorous substances by chemical reactions such as neutralization, addition, polymerization, oxidation, reduction, and hydrolysis to decomposing or odorless compounds. ;

2) Physical and chemical removal method

As a compound having strong adsorption and trapping ability, such as activated carbon, silica, and cyclodextrin, the odor component is adsorbed or collected on the surface, or is coated by using high boiling point solvent, surfactant, etc., liquid paraffin, higher alcohol, synthetic resin, etc. Removing odorous substances;

3) Biochemical Removal

A method for blocking the generation of odor components by bacteria by sterilizing action by an amphoteric surfactant or a fungicide, or by removing digestive odor by decomposing organic acids as odor components using digestive enzymes, bacteria, yeasts, etc .; And

4) Sensory deodorization method

Removal method by odor masking that uses aromatic fragrance for target odor component to offset sensory neutralization or odor.

On the other hand, most of the odor-causing substances that cause discomfort from clothing or textile products are caused by cigarette smell, cooking food smell, sweat or body odor, kimchi vegetable smell, bacteria or mold smell, and various decaying odors. These odorous substances are mainly ammonia, amines, acids, alcohols, aldehydes, ketones, phenolics, polycyclics and indoles. ), Basic compounds such as aromatics, polyaromatics, or volatilized compounds, and sulfide compounds such as thiol, mercaptane, and sulfide. In order to remove such various odor sources from clothes or textile products, it can be removed by washing or dry cleaning. In the case of targeting textile products such as curtains and carpets, which are cumbersome or difficult to wash, the odor that is doubled in textiles It is known that it is much easier to remove odor-causing substances by applying a deodorizing substance such as easily adsorbing or decomposing the substance directly on the fiber surface. However, the deodorizing method of directly applying deodorant components such as adsorption and decomposition of odorous substances soaked on the surface of various fibers can continuously and easily remove odors in a wide range of areas and must not have its own smell. There is a restriction that no damage to the textile product is made.

Until now, the odor removal technology for clothing and textile products has been focused on masking methods by incense, not fundamental elimination of odor component itself. It was true that the method of deodorizing a real smell was insufficient.

Therefore, in recent years, the deodorization technology for the purpose of removing the odor component of the ban on clothing or textiles has been actively developed. Representatively, the techniques of deodorizing by spraying on the surface of clothing and textiles with cyclodextrine, a cyclic polysaccharide, and metal minerals as main ingredients and adding masking fragrance have been introduced (US Pat. Nos. 5,534,165, 5,593,670, 5,668,097 , No. 5,714,137, 5,882,638), which are chemically decomposed of odorous substances during masking with aroma and capture odorous substances from which cyclodextrine decomposes during drying of moisture. It is described as a way to remove it. Such deodorization technology has almost no damage to fiber and shows excellent deodorizing effect on basic odors such as ammonia and amine compounds and volatilized odorous substances such as tobacco odor, but it is acidic such as kimchi vegetable smell and food odor. There is a disadvantage in that there is almost no deodorizing effect, and if the fiber is wetted again by moisture after drying, the odorous substance collected by the exchange of odorous substances trapped in cyclodextrin and moisture is released as it is, and the discomfort may be felt again. Cyclodextrins composed of glucose can produce microorganisms on the fiber without proper use of antimicrobial agents and preservatives, and even if they remain on the fiber surface for a long time, the fungus will easily proliferate and smell or discolor the fiber. It becomes the cause and is not good.

In addition, as an effective natural extract known to have a deodorant effect, dozens of species such as flavonoids, wheaten cheese, green tea extracts, mushroom extracts, bamboo extracts and wood vinegar have been known so far, but the use of deodorants in clothing and textile products is insufficient and economical. Inadequately, when used alone, it takes a long time to deodorize and is not suitable for use as a fiber deodorant, such as causing yellowing or discoloration problems in clothing or textile products.

Therefore, the present inventors have conducted intensive studies to obtain a new deodorant composition which can be safely and easily deodorized without damaging clothing and textile products, and thus can be easily used in clothing and textile products, and it can be used in tobacco and meat and fish dishes. In the early days, we found a new fiber deodorant composition with excellent deodorizing effect and excellent antibacterial effect for various odorous substances such as Kimchi smell, which is a characteristic of Korean food culture, as well as bacteria and mold smell.

SUMMARY OF THE INVENTION An object of the present invention is to provide a fiber deodorant composition which essentially contains an inorganic metal complex compound as a fiber deodorant main component of odorous substances which are free from dyeing or discoloration, and are safe for humans.

[Means for solving the problem]

Hereinafter, the present invention will be described in detail.

[Action]

The initial deodorizing power in the fiber deodorant is a very important factor to promptly recognize the deodorant effect to the user, the metal complex compound used in the present invention has a particularly strong characteristic of acid odor such as kimchi, vegetable odor.

As the main component of the fiber deodorant of the present invention, the colloidal inorganic metal complex compound contains 0.01 to 12% by weight and is an colloidal inorganic metal complex compound having an average particle size of 1 to 10 nm in which copper or zinc metal is supported on titanium oxide. In addition, the metal complex of the present invention uses titanium oxide (TiO ₂ ) suitable for the raw material standards of cosmetics as a substrate, and stably supported copper (Cu) or zinc (Zn) metal on the substrate.

The deodorizing mechanism in the fiber of this compound is to deodorize various odorous substances by the decomposition action by photocatalytic reaction, unlike physical, chemical adsorption or fragrance masking, which is the mainstream, and is excited by temperature rise and ultraviolet irradiation. It is characterized by an increase in the decomposition reaction rate, and it is also a great advantage that the deodorization effect can be maintained in the long term without saturation degradation, which is a drawback of adsorption deodorization. In addition, the metal complex compound exhibits almost perfect deodorizing effect against sulfide compounds such as hydrogen sulfide and methylmecaptan, which are the main components of acidic odor, and moreover, smells such as ammonia and trimethylamine, which are basic odors, and acetaldehyde, which are volatile odors. The material also showed a very good deodorizing effect.

In addition, the persimmon leaf extract, which is a natural plant extract, and glyoxal may be optionally contained alone or in combination. The fiber deodorant composition of the present invention may decompose malodorous substances at the initial stage by the metal ions of the inorganic metal complex compound and the persimmon leaf extract. The main components of tannins, polyphenols and organic glyoxal compounds are chemically added or condensed with components of various odorous substances to change into non-volatile odorous substances and exhibit a deodorizing mechanism to suppress or remove odors. .

In addition, the persimmon leaf extract used as a component of the fiber deodorant in the present invention is characterized by selectively containing 0.1 to 15% by weight as a plant extract component, the tannin component and polyphenols, condensed tannins, organic polymers, etc. It removes odorous substances by chemical deodorization such as neutralization and addition, substitution and reduction, and physical inclusion, adsorption and absorption by neutralizing and adding odor gas components such as ammonia, trimethylamine, hydrogen sulfide and methylmecaptan by the complex action of There is this.

In addition, the fiber deodorant composition in the present invention is characterized in that it contains 0.1 to 8% by weight of glyoxal compounds that remove basic and volatilizing odorous substances, and in particular exhibit an excellent antibacterial effect by inhibiting bacteria and fungi, The highly reactive terminal hydroxy group removes odorous substances by deodorizing by chemical reactions such as neutralization, addition and condensation of basic and volatilizable functional groups of various odorous components.

On the other hand, the characteristics of the fiber deodorant composition of the present invention is not discoloration, dyeing, discoloration or other fiber damages to natural fibers such as various cotton or synthetic fibers such as polyester, and even when exposed to sunlight, discoloration of the shape and color of the fiber and There is an advantage that it can be safely used in textile products such as clothing, carpets, curtains because it does not damage the fiber, such as dyeing.

In addition, the fiber deodorant composition of the present invention may contain a fresh and subtle fragrance to give a pleasant fragrance to the textile product after deodorization, but very small amount within the range that does not affect the physical stability or deodorizing effect for the composition of the present invention It may also contain a very small amount of natural antibacterial components such as known triclosan (Swiss, Ciba Specialty Co., Ltd.) or grapefruit extract for the purpose of further improving the antimicrobial effect, to preserve the phase stability of the fiber deodorant composition of the present invention over time For the purpose of preserving a small amount of a nonionic surfactant such as polyoxyethylene alkyl ether or a solubilizing solvent such as propylene glycol, or to impart an antistatic effect to fibers and clothing, various static electricity such as a known cationic surfactant. Selective small amount of inhibitor Although it may be used, the stability and deodorizing effect of the composition of the present invention and the like should be within a range without affecting the composition of the present invention by the various additives and the like.
