Description

[Detailed description of the invention]

[Industrial Field of Application] The present invention relates to a novel deodorant. More specifically, the present invention relates to a deodorizing agent mainly containing a resin powder coated with an organic halogen compound or an aluminum inorganic salt as an active ingredient to reduce bad odors originating from living organisms. This deodorant is highly safe for living organisms, and is expected to be used in fields such as pharmaceuticals and cosmetics. [Prior Art] Most explanations for the causes of body-derived bad odors such as armpit odor, sweat odor, foot odor, hair odor, and menstrual odor are that they are caused by bacterial decomposition of sweat (e.g., Labows and Kligman). (Kligman) et al., J.Soc.Cosmet., Volume 34, 1982
, p. 193}. There are many products on the market aimed at reducing these bad odors, but most of these are masking products that mainly use antiperspirants such as aluminum hydroxychloride, disinfectants such as quaternary ammonium compounds, and pleasant odors such as eugenol. It is formulated with adsorbents such as active carbon or activated carbon alone or in combination. [Problems to be solved by the invention] However, these conventional deodorants are insufficiently effective, lack long-lasting effects, or are not fully satisfactory in terms of safety and usability when applied locally. It wasn't something. In view of the above circumstances, the present inventors have determined that the safety is high,
As a result of intensive research in order to obtain a deodorant that has truly excellent deodorizing effects and a long-lasting effect, we have surprisingly found that resin powder has a deodorizing effect. The inventors discovered that coating with inorganic salts dramatically increases the deodorizing effect, leading to the present invention. [Means for Solving the Problems] That is, the present invention provides a deodorant characterized by containing as an active ingredient a resin powder coated with an organic halogen compound or an aluminum inorganic salt. Product forms include external deodorants such as aerosols, roll-ons, powders, lotions, creams, and sticks, as well as shoe soles and household deodorants. The present invention will be explained in detail below. Examples of the resin powder constituting the resin powder coated with the organic halogen compound or aluminum inorganic salt of the present invention include nylon, polyvinyl alcohol, polyvinyldene chloride, polyvinyl chloride, polyester, polyacrylonitrile, polyethylene, polypropylene, and polycyanide. vinyldene,
Examples include polyurea, polystyrene, polyurethane polyfluoroethylene, and the like. Among these, nylon is preferable. On the other hand, examples of organic halogen compounds constituting the resin powder coated with organic halogen compounds or aluminum inorganic salts include hexachlorophene, benzethonium chloride, benzalkonium chloride aluminum hydroxychloride, aluminum zirconium chlorohydrate, berberine chloride, copper Examples include chlorophyll. Among these, aluminum hydroxychloride is preferred. Commercially available resin powders, organic halogen compounds, or aluminum inorganic salts may be used, but the resin powder preferably has a particle size of 0.1 to 20 μm, more preferably 0.1 to 10 μm. For deodorizing, it is preferable that the particle size of the resin powder is small because it is larger and also has higher transparency when applied to the skin. A known method can be used to coat the organic halogen compound or aluminum inorganic salt onto the resin powder, and the most convenient method is a mechanochemical method. The amount of organic halogen compound or aluminum inorganic salt present on the resin powder is preferably about 10% or more based on the weight of the resin powder. The upper limit is about 100%. The amount of the resin powder coated with the organic halogen compound or aluminum inorganic salt thus obtained is effective at 0.1% by weight or more in the deodorant base. There is no upper limit. [Effects of the Invention] Hereinafter, the present invention will be explained in more detail by giving test examples of the deodorizing effect of a deodorant containing a resin powder coated with the organic halogen compound or aluminum inorganic salt of the present invention. The test method is as follows. (Deodorization test method) Panel 6 of healthy men who are aware of having armpit odor
A test was conducted using the name. A total of 4 doses of the test product with the following formulation were administered once in the morning and once in the afternoon every day for 2 days.
It was applied to one armpit of each subject. The other armpit, which is not applied, is used as a control. (Test product formulation) Coated with aluminum hydroxychloride
12 Nylon (*1) 60% by weight Talc 40% by weight *1 Obtained by coating 80 g of 12 Nylon with an average particle size of 5 μm with 20 g of aluminum hydroxychloride by mechanochemical treatment using a ball mill. (Judgment and Evaluation) The effectiveness was judged according to the following 5-level criteria. 0: No armpit odor 1: Slight armpit odor 2: Distinct armpit odor 3: Armpit odor 4: Very strong armpit odor Average underarm odor of 6 people over time The value was calculated and used to evaluate the deodorizing effect. The results are shown in Table-1. The effects of the deodorant of the present invention are clear.

[Table] Nylon 12 with an average particle size of 20 μm and an average particle size of 5 μm
12 nylon was used for testing. The results are shown in Table-2.

[Table] According to the above test method, the deodorizing effects of the two formulations shown in Table 3 below were evaluated.

[Table] The results are shown in Table 4. The deodorant of the present invention has a lower level of deodorization compared to conventional products that simply contain aluminum hydroxychloride.
It can be seen that the effect is excellent.

[Table] [Examples] Examples are shown below, but the present invention is not limited thereto. (Example 1) A deodorizing powder having the following composition was prepared. coated with aluminum hydroxychloride
12 Nylon (*2) 0.1 Talc 79.9 Kaolin 20.0 When we conducted a deodorizing effect test using the above powder, we found that after the start of the test, the intensity of armpit odor in the test area was 5% compared to the control area. significantly decreased. (Example 2) A deodorizing powder having the following composition was prepared. Polyethylene coated with benzalkonium chloride (*3) 5.0 Talc 85.0 Kaolin 10.0 *3 50 g of polyethylene with an average particle size of 5 μm was coated with 50 g of benzalkonium chloride by mechanochemical treatment using a ball mill. When a deodorizing effect test was conducted using the above powder, after the start of the test, the intensity of armpit odor in the test area was significantly reduced at a risk rate of 5% in all panels compared to the control area. (Example 3) A deodorizing spray having the following composition was prepared. Freon 11 76.8% Freon 12 19.2 Coated with aluminum hydroxychloride
12 Nylon (*2) 0.6 Talc 2.4 Isopropyl myristate 0.5 Diglycerol sorbitan tetra-2-ethylhexanoate 0.5 In the actual use test using this spray, after the start of the test, the strength of armpit odor in the test area was compared for each panel. There was a significant decrease in the risk rate of 5% compared to the previous year. (Example 4) A deodorant lotion having the following composition was prepared. Purified water 82.0 Ethanol 15.0 Sorbit 2.0 Coated with aluminum hydroxychloride
12 Nylon (*2) 1.0 In actual use tests using this lotion, after the start of the test, the intensity of armpit odor in the test area was significantly reduced at a risk rate of 5% compared to the control area in all panels.
It confirmed its effectiveness.
