There is no description, and this shampoo requires a cumbersome procedure of rubbing the scalp, keeping it for 25 minutes, and then washing off the shampoo.
- Patent Document 3 also discloses a shampoo containing a composition of zinc pyrithione and metal ions including zinc ions from zinc oxide. It has been suggested that this composition enhances the antibacterial activity against malassezia causing dandruff and, as a result, enhances the anti-dandruff effect. However, the ultrafine zinc oxide having an average particle size of 0.15 ⁇ m or less is suggested. There is no description.

- One kind of the particulate zinc oxide describes zinc oxide that can be estimated as fine zinc oxide having an average particle diameter of 0.06 ⁇ m, and an example of a shampoo formulated with zinc pyrithione is shown. Since the pH of the shampoo solution is adjusted to be weakly acidic, the complex produced only at pH 8 or higher of the present invention is not generated.

- zinc pyrithione is formulated in shampoos as an anti-dandruff agent, but it has a strong irritating effect on the ocular mucosa, and as much as possible without reducing the anti-dandruff effect for environmental hygiene reasons. Efforts to reduce it continue.
- a hair-growth shampoo containing zinc oxide needs to be kept as it is for about 25 minutes after the shampoo is rubbed into the scalp in order to obtain a hair-growth effect and a hair loss suppressing effect. Therefore, there has been a demand for a technique that can achieve the effect even in a normal use in which the hair is washed with water immediately after shampooing.

Abstract
Description
また酸化亜鉛を含む育毛シャンプーは、育毛効果・脱毛抑制効果を得るためにはシャンプーを頭皮に擦り込んだ後、25分間ほどそのままの状態に保つ必要がある。したがって、シャンプーによる洗髪をした後すぐに頭髪を水洗いするという通常の使用においても、その効果が得られる技術が求められていた。
即ち、本発明は、
(1)
一般式(I)
xZnO・ZnPy2 (I)
(式中xは0≦x≦1を満足する0又は正数、Pyは2-ピリジルチオ-N-オキサイド基を表す。)

である。
ここで、亜鉛ピリチオン・酸化亜鉛複合化合物とは、亜鉛ピリチオンと非晶質酸化亜鉛が複合化してできた複合化合物を意味し、反応混合物をクロロホルムで抽出することにより、結晶性酸化亜鉛粒子を分離・除去することによって得られるものである。得られたクロロホルム抽出物は、亜鉛ピリチオンより多い亜鉛含量を有するが、非晶質であるがゆえにX線回折分析で酸化亜鉛の回折角ピークが認められない。また亜鉛ピリチオン又は亜鉛ピリチオン・酸化亜鉛複合化合物と超微粒酸化亜鉛との複合体は、亜鉛ピリチオン又は亜鉛ピリチオン・酸化亜鉛複合化合物に平均粒子径0.01~0.15μmの超微粒酸化亜鉛が結合した複合体を意味し、XPS(X線電子分光法)分析によって、Zn2p3の結合エネルギーが下方にシフトし、しかもピークが1箇所であること、また図6に示したSEM(走査型電子顕微鏡)写真によって亜鉛ピリチオン粒子の表面上に目視可能な超微粒酸化亜鉛粒子が密着した外観を呈することからも確認できる。また複合体は、X線回折分析で酸化亜鉛の回折角ピークを示す点でも、複合化合物と相違している。
亜鉛ピリチオンと超微粒酸化亜鉛をアルカリ処理したとき、複合体が形成することは、処理物のDTA(示差熱分析)の発熱ピーク温度が約15℃上昇し(実施例1)、また前述したようにXPS分析で酸化亜鉛、亜鉛ピリチオンZn2P3の結合エネルギーを示すそれぞれのスペクトルピークがなくなり、下方にシフトしていることから明らかである。一方亜鉛ピリチオンと超微粒酸化亜鉛との混合物のXPS分析では、亜鉛ピリチオンと超微粒酸化亜鉛のそれぞれのスペクトルピークを示すピークが認められた。
さらに本発明の新規結晶性亜鉛ピリチオン・酸化亜鉛複合体と亜鉛ピリチオンと超微粒酸化亜鉛との混合物、即ち組成物との違いは、抗菌力、育毛効果にも顕著に現れている。本発明の複合体は、亜鉛ピリチオンと超微粒酸化亜鉛との組成物と比べ、Malassezia菌に対して2倍の抗菌力、2倍以上の育毛効果を有している。
また本発明の複合体は、亜鉛ピリチオンと超微粒酸化亜鉛との混合物に比べ、エマルジョン塗料の主要汚染菌である大腸菌、緑膿菌に対し、2~4倍の抗菌効果を示すとともに、亜酸化銅配合船底塗料において、貯蔵中のゲル化抑止効果も優れている。
水懸濁液又は水性ペーストの攪拌時、特に加熱を必要としないが、20~95℃に加温してもよい。攪拌時間は、通常5分~4時間、好ましくは10分~3時間である。水懸濁液又は水性ペーストのpHを調節するための好適なアルカリ化剤としては水酸化ナトリウム、水酸化カリウム、炭酸ナトリウム、アンモニアを挙げることができる。
亜鉛ピリチオン・酸化亜鉛複合化合物の生成は、得られた白色粉末をクロロホルムで抽出し、クロロホルム抽出物の亜鉛含量が亜鉛ピリチオンの亜鉛含量を超えたときに認められる。従ってこの場合、本発明の亜鉛ピリチオン・酸化亜鉛複合体は、亜鉛ピリチオン・酸化亜鉛複合化合物と平均粒子径0.01~0.15μmの超微粒酸化亜鉛からなる複合体を含有している。
本発明の抗生物活性複合体とイソチアゾロン系防腐防黴成分は、10:1~1:10の重量比率で配合される。上記工業製品の防腐成分としては合わせて0.005~1.0重量%、好ましくは0.01~0.5重量%、防黴成分としては、合わせて0.1~5重量%、好ましくは0.5~2.5重量%用いられる。
この白色粉末の800mgを2回採り、それぞれ1リットルのフラスコに入れたクロロホルム600mLに加えた。この液を60℃で60分攪拌した後、メンブランフィルターでろ過し、乾燥した。得られたフィルター上の白色粉末(i)は第1回目150mg、第2回目160mgであり、またろ液を蒸留して得られた白色粉末(ii)は、第1回目640mg、第2回目630mgであった。
さらに(i)と(ii)について、それぞれ蛍光X線分析を行った。その結果、(i)については実質的に亜鉛のみで、亜鉛ピリチオン由来の硫黄は検出できなかった。また(ii)については、亜鉛ピリチオン中に含まれる硫黄との対比から、原料亜鉛ピリチオンの亜鉛含量の1.09倍(2回平均値)の亜鉛が含まれていた。即ち亜鉛ピリチオンに対しモル比で9%の酸化亜鉛が結合した亜鉛ピリチオン・酸化亜鉛複合化合物(x=0.09)とx=0.91の超微粒酸化亜鉛からなる複合体が得られた。なお上記クロロホルム抽出物(ii)は、X線回折分析の結果、酸化亜鉛固有の回折角ピークを示さないので、亜鉛ピリチオンに結合している酸化亜鉛は非晶質と考えられる。またこのクロロホルム抽出物をXPS分析した結果を図1に示した。Zn2p3の結合エネルギーは、亜鉛ピリチオンのそれ(図5)より0.3eV下方にシフトしていた。また超微粒酸化亜鉛の結合エネルギーを示すスペクトルピーク(図4)はなくなっていた。
得られた白色粉末の800mgを取り、実施例1と同様にクロロホルム抽出を行って得た留去残は、蛍光X線分析により、亜鉛ピリチオンに対し1.04倍の亜鉛を含んでいた。即ち亜鉛ピリチオンに対しモル比で4%の酸化亜鉛が結合した亜鉛ピリチオン・酸化亜鉛複合化合物(x=0.04)とx=0.21の超微粒酸化亜鉛からなる複合体が得られた。この複合体をXPS分析した結果を図3に示す。Zn2p3の結合エネルギースペクトルピークは単一であり、超微粒酸化亜鉛、亜鉛ピリチオンの結合エネルギー(図4、5)よりそれぞれ1.4eV、0.4eV下方にシフトしていた。
得られた白色粉末(A)3.4g、超微粒酸化亜鉛(テイカ株式会社製、平均粒子径0.03μm)0.6gを200mLのビーカーに入れた蒸留水80mLに加えて(pH8)、後は実施例2と同様の操作を行い、白色粉末(B)3.8gを得た。このものの示差熱分析を行った結果、発熱ピーク温度は、307.4℃(補正後)であった。
