Description

【0001】
【発明の属する技術分野】
この発明は、台所の流し台、風呂場、洗面台などの排水口、トイレ洗浄水タンクの上部流入口、男子用小便器内などに設置して、除菌、消臭、漂白あるいはヌメリ防止等に有用な活性酸素を、長期間に亘って放出しうる錠剤を提供するものである。
【0002】
【従来の技術】
塩素化イソシアヌル酸系化合物は、排水等の殺菌消毒剤あるいはスライムコントロール剤として従来より使用されており(例えば特公昭61−41883号公報)、なかでもトリクロロイソシアヌル酸は溶解度が低く、水中において持続性が優れた錠剤と為し得るので、台所流し台における排水口のヌメリ取り剤として用いられている(例えば特開平8−231314号公報)。
特開平8−268818号公報には、過炭酸ナトリウムをパラフィンワックスなどでコーティングした持続性のヌメリ取り剤が開示されているが、本品は溶解性が乏しく実用に供し難いものである。また特開2000−144840号公報には、非塩素系薬剤としてイソチアゾリン系薬剤を用いた排水口のヌメリ取り装置が提案されている。
【0003】
【発明が解決しようとする課題】
この発明は、台所流し台、風呂場、洗面台などの排水口、トイレ洗浄水タンクの流入口、男子小便器等に使用する際に、塩素ガスが発生せずまた金属の腐食によるトラブルを回避し、且つ水中において殺菌、消臭、漂白、除菌、ヌメリ取りなどの作用を、長期間に亘って維持しうる錠剤を提供することにある。
【0004】
【課題を解決するための手段】
本発明者等はこのような事情に鑑み鋭意研究の結果、活性酸素を放出しうるペルオキシ一硫酸カリウム・硫酸水素カリウム・硫酸カリウムの複塩化合物、過硫酸カリウム及び過硫酸ナトリウムから選ばれる1種または2種以上の化合物、並びに常温で固体の有機酸及び脂肪酸化合物を均一に配合し、打錠成形することによって所期の目的を達成したものである。
【0005】
この発明によれば、ペルオキシ一硫酸カリウム・硫酸水素カリウム・硫酸カリウムの複塩化合物、過硫酸カリウム及び過硫酸ナトリウムなどの活性酸素を放出しうる化合物と、常温で固体の有機酸及び脂肪酸化合物を混合し、圧縮成形して錠剤としたものであるから、粉末もしくは顆粒状のものに比べて水との接触面積が小さいので、活性酸素を放出しうる化合物と水との接触が制限され、錠剤の形状を維持しながら長時間に亘って活性酸素を放出させることができる。
【0006】
【発明の実施の形態】
本発明の実施に適する水と接触して活性酸素を放出しうる化合物は、ペルオキシ一硫酸カリウム・硫酸水素カリウム・硫酸カリウムの複塩化合物(化学式:2KHSO・KHSO・KSO、以下、オキソン一過硫酸化合物という)、過硫酸カリウム及び過硫酸ナトリウムであり、これら以外の活性酸素を放出しうる化合物として知られている過炭酸ナトリウム、過ほう酸ナトリウムは、保存安定性あるいは徐溶性の観点から使用に適さない。
錠剤中に配合する活性酸素を放出する化合物の配合比率は20〜70重量%が好ましい。前記化合物の配合量が20重量%より少ない場合には、ヌメリを防止する充分な効果が得られず、70重量%を超えて配合してもコスト高を招き、経済的な観点から好ましくない。
【0007】
本発明において使用される有機酸は、常温で固体であり且つ適宜な溶解性と打錠成形性を備えるものが好ましい。代表的な有機酸としてはクエン酸、コハク酸、アジピン酸、フマル酸、安息香酸及びサリチル酸等であり、これらから選ばれて少なくとも安息香酸を含む1種または2種以上を混合して使用することができる。
錠剤中に配合する有機酸の配合比率は10〜70重量%が好ましい。有機酸の配合量が10重量%より少ない場合には、錠剤の打錠性が悪くなり生産性の低下をもたらすばかりか、外観の整った錠剤が得られなくなる。また70重量%を超えて配合しても、下記脂肪酸化合物の必要な含有量が確保できず好ましくない。
【0008】
本発明において使用する常温で固体の脂肪酸化合物として、椰子油脂肪酸モノエタノールアミド、ステアリン酸モノエタノールアミド、ラウリン酸モノイソプロパノールアミド、モノステアリン酸ポリエチレングリコール、ジステアリン酸ポリエチレングリコール、モノステアリン酸エチレングリコール及びジステアリン酸エチレングリコールなどが代表的なものとして挙げられる。
錠剤中における脂肪酸化合物の配合比率は、10〜70重量%が好ましい。脂肪酸化合物の配合量が10重量%より少ない場合には、錠剤の包接力が低下し水中において錠剤形状を維持することができず、70重量%を超えて配合してもいたずらにコスト高を招来するばかりか、有機酸の必要な含有量を確保できず好ましくない。
【0009】
錠剤成形に当たっては、通常使用されているアルキル硫酸塩、アルキルベンゼンスルホン酸塩等の界面活性剤、ステアリン酸塩等の滑沢剤、香料等の着臭剤、顔料等の着色剤も使用できる。
また錠剤の成形に当たっては、組成混合物を直接圧縮して錠剤化することができるが、予備加熱してその一部を溶融させたのち、冷却し整粒したものを圧縮して錠剤化することも可能である。
