However , when the body odor suppressing agent containing activated CROSS -REFERENCE TO RELATED carbon is applied to the skin , clothes , or the like by spraying APPLICATIONS or other means, the skin or the like coated with the body odor 5 suppressing agent is soiled with black residue, and this This application is a Continuation Application of patent attempt reveals that such an agent is unsuited for practical application Ser . No . 14 /415 ,493 , filed on Jan . 16 , 2015 , use In addition , when applied to the skin , the agent causes which is a 371 application of Application Serial No . PCT/ roughness on the skin after coating , and has a lower feeling JP2013 /082619 , filed on Dec . 4 , 2013 , which is based on of use . Moreover , when packed into a spray container and Japanese Patent Application No . 2012 - 268359 filed on Dec . 10 used , the agent readily causes clogging of the nozzle . Patent 7 , 2012 , the entire contents of which are hereby incorporated Document 3 describes no problem of the soiling, the feeling of use , or the clogging of nozzles at all. In other words, no by reference . body odor suppressing agent containing activated carbon , TECHNICAL FIELD but causing no black soiling on an object to be coated , such 15 as the skin , and having excellent practical aptitude has been The present invention relates to a body odor suppressing found , as well no body odor suppressing agent having an agent. Specifically , the present invention relates to a body excellent feeling of use or no body odor suppressing agent odor suppressing agent that is applied to skin to exert capable of preventing nozzles from clogging has also been excellent deodorizing effects on body odor such as hircis found . mus. 20 Therefore , it is an object of the present invention to provide a body odor suppressing agent that contains acti BACKGROUND ART vated carbon and that has excellent body odor suppressing effects , causes no black soiling on an object to be coated , and Hircismus , foot odor, sweat odor, and other body odors , has excellent practical aptitude . An object of the present which make people uncomfortable , are typically generated 25 invention is to provide a body odor suppressing agent having by decomposition of a mixture of sweat and lipids such as an excellent feeling of use when the agent is applied to the sebum by skin normal florae . For example , hircismus results skin . An object of the present invention is to provide a body from , for example, the odor of fatty acids as degradation odor suppressing agent capable of preventing nozzles from products of lipids contained in secretions secreted from the clogging when the agent is packed into a spray container and apocrine glands present on the axilla . 30 used . In order to suppress such body odor, various techniques such as bactericides, antiperspirants , and deodorants have Solution to Problem been used ( for example, see Non - Patent Document 1 ) . For example , deodorant ; compositions containing zinc oxide and As a result of intensive studies, the inventors of the silica as deodorant components are known ( for example, see 35 present invention have found that by mixing a titanium Patent Document 1 and Patent Document 2 ) , However, oxide - coated activated carbon in which a titanium oxide is much higher suppressive function on the body odor has been present over the surface of an activated carbon having an demanded . For example , a deodorant component having average particle diameter within a particular range, a body more excellent deodorizing function has been demanded . odor suppressing agent having excellent body odor sup A skin lotion for removing body odor has been developed 40 pressing effects , causing no black soiling on an object to be while focusing on the adsorption function of charcoal. The coated , such as the skin , and having excellent practical skin lotion is prepared by mixing a common skin lotion with aptitude can be obtained , have found that the body odor coconut shell activated carbon and other components ( see suppressing agent also has an excellent feeling of use when Patent . Document 3 ) . the agent is applied to the skin and that the agent can prevent 45 nozzles from clogging when the agent is packed into a spray CITATION LIST container and used , and have accomplished the present invention . Patent Literature In other words, the present invention provides a body odor suppressing agent including a titanium oxide- coated acti Patent Document 1 : JP - A No, 2011 - 148785 50 vated carbon including an activated carbon having an aver Patent Document 2 : JP - A No . 2009 - 209043 age particle diameter of 15 to 50 um and a titanium oxide Patent Document 3 : JP - A No. 2002 - 145747 present over a surface of the activated carbon . The titanium oxide preferably has an average particle Non -Patent Literature diameter of 0 .01 to 0 . 5 um . 55 The titanium oxide preferably has a weight ratio of 500 to Non -Patent Document 1 : “New Cosmetic Science ( Shin 1 , 500 parts by weight relative to 100 parts by weight of the Keshouhingaku ) ” , second edition , edited by Takeo Mitsui. activated carbon . NANZANDO Co . , Ltd ., pp . 510 - 515 ( 2001) Advantageous Effects of Invention SUMMARY OF INVENTION 60 A body odor suppressing agent of the present invention Technical Problem has the configuration above and thus has excellent body odor suppressing effects . The body odor suppressing agent causes The inventors of the present invention have found that no black soiling on an object to be coated , such as the skin activated carbon has excellent a deodorizing function as 65 when applied to the skin , clothes , or the like by spraying or compared with conventional deodorant components such as other means and has excellent practical aptitude . When the zinc oxide and have attempted to prepare a body odor body odor suppressing agent is applied to the skin , the skin US 9 ,737 ,467 B2 after coating is smooth , and the agent has an excellent an average particle diameter of more than 50 um , the body feeling of use.
