DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an aqueous deodorant composition useful for clothing such as suits, fabrics, and textiles such as curtains for lace fabrics.

2. Description of the Related Art Generally, various odors such as tobacco odor and aldehyde odor adhere to clothing such as suits and coats and textiles such as curtains for living rooms. Since these products have a relatively low frequency of washing, the attached bad smell is generally naturally removed by passing air. 2. Description of the Related Art Conventional deodorizing technology, for example, masking using a perfume having a stronger odor than malodor is widely known as a countermeasure against malodor in the air. However, when this is directly applied for deodorizing textiles such as clothing, there is a problem that a strong fragrance of the fragrance is attached to the fiber and the residual scent is unpleasantly felt. As an example of another deodorizing technique, it is known to use vegetable essential oil. For example, mist type hair cosmetics containing natural essential oils such as orange (JP-A-9-103473),
Deodorant containing vegetable essential oil (JP-A-7-171209) and deodorant containing vegetable essential oil such as lemongrass oil (JP-A-5-2691)
85) and a method for producing deodorant substances from plants of the family Lamiaceae (Japanese
57-204278). These do not cause unpleasant odor after use as compared with the masking. However, although these deodorants are effective mainly for deodorizing air and deodorizing hard surfaces, etc., they are satisfactory for removing unpleasant odors attached to clothing and other fibers. I couldn't do it.

SUMMARY OF THE INVENTION The present invention provides an aqueous deodorant composition for textiles having a high deodorizing effect on textiles such as clothing and curtains.

[0003]

Means for Solving the Problems The present inventors have conducted intensive studies to achieve the above object, and as a result, have found that a deodorant base extracted from a plant and a nonionic surfactant and / or a polyether-modified silicone can be used. The above-mentioned problem was solved by using in combination, and the present invention was achieved. That is, the present invention relates to a textile product comprising (A) a deodorant base extracted from a plant, (B) a nonionic surfactant and / or a polyether-modified silicone, and (C) a water-soluble solvent. An aqueous deodorant composition is provided.

BEST MODE FOR CARRYING OUT THE INVENTION Component (A): Deodorant base extracted from plants In the present invention, the deodorant base means a base having a deodorizing effect extracted from plants. Various bases having a deodorizing effect are known, and these can be used arbitrarily. Specific examples include Lamiaceae plants such as sage, rosemary, ogre, oregano, marjoram, black mint, mebuki, tachikou, thyme, melissa, naginata kouju, savory, etc., cloves, eucalyptus etc., and rose family Extracts from plants, cypress plants, Lentinaceae plants such as Forsythia plants, and other extracts from plants such as Suo, Sugarcane, Kobushi, Magnolia and Rhubarb. Among these, a preferable deodorant base is an extract of a Labiatae plant, and sage and rosemary are particularly preferably used.

[0004] The method of extracting the above-mentioned base from plants is not particularly limited, but can be obtained, for example, by the following method. The raw material plant is soaked or powdered and immersed in a polar solvent, and heated at a temperature from room temperature to a solvent reflux temperature for 0.5 to 24 hours, preferably 1 to 10 hours. Examples of the solvent include water and organic solvents such as ethanol, propylene glycol, dioxane, methanol, acetone, ethyl ether, ethylene chloride, and isopropanol. A base extracted with water as a solvent is particularly excellent in deodorizing effect. . Immediately after heating, or after further immersion at room temperature for several days, the extract is separated from the residue by a method such as filtration or centrifugation. The obtained extract may be used as it is as a deodorant, but preferably, the solvent is distilled off by distillation or the like. The amount of the deodorant base in the present deodorant composition is 0.01 to 3%, preferably 0.03 to 2%.
%. When used in this range, a sufficient deodorizing effect is obtained, and the aroma of the deodorant remaining in the fibers after use is not too strong.

The nonionic surfactant represented by the formula preferably has an HLB value of 8 to 16, particularly preferably 8 to 14, due to griffin. When a nonionic surfactant of HLB in this range is used, the deodorant base easily penetrates into textiles, and a high deodorant effect is obtained, and the liquid stability is also excellent. These surfactants can be basically produced by a known method.

As the polyether-type modified silicone used in the present invention, various modified silicones can be mentioned, but a modified silicone having a polyoxyethylene chain is preferred. More preferably, the weight ratio of polyoxyethylene chains per molecule is from 25 to 80%, particularly preferably from 30 to 75%, based on the total weight of the polyether-modified silicone.

As with nonionic surfactants, when the polymerization ratio of the polyoxyethylene chain is in this range, the deodorant base easily penetrates into textiles, and a high deodorant effect is obtained. Excellent. A preferred polyether-type modified silicone is represented by the following formula (II).
