Description
本発明は、トイレ用固形洗浄剤に関し、詳しくは、便器ボウル内面に付着させて用いられるトイレ用固形洗浄剤、及び該固形洗浄剤を用いた便器ボウル内面の洗浄方法に関する。 The present invention relates to a solid cleaning agent for toilets, and more particularly to a solid cleaning agent for toilets used by adhering to the inner surface of a toilet bowl, and a method for cleaning the inner surface of a toilet bowl using the solid cleaning agent.
従来よりトイレの便器を洗浄する方法として、例えば、洗浄剤を貯水タンクに投入して使用する方法(インタンク方式)、貯水タンク上蓋の注水口に洗浄剤を容器等に収納し配置して使用する方法(オンタンク方式)等が知られている。 Conventionally, as a method of cleaning a toilet bowl, for example, a method of putting a cleaning agent into a water storage tank and using it (in-tank method), a method of storing and arranging a cleaning agent in a container or the like at a water injection port of a water storage tank top lid is used. The method of cleaning (on-tank method) is known.
また近年ではタンクレス便器の普及に伴い、便器の洗浄方法にも変化が見られており、例えば、洗浄剤を容器に収納し便器の縁に吊り下げて使用する方法(リムブロック)、ゲル状洗浄剤を便器のボウル内面に付着させて使用する方法等が広がりつつある。 In recent years, with the spread of tankless toilet bowls, changes have been seen in the cleaning method of toilet bowls. For example, a method of storing a cleaning agent in a container and hanging it on the edge of the toilet bowl (rim block), gel-like Methods of using a cleaning agent by adhering it to the inner surface of a bowl of a toilet bowl are becoming widespread.
このようなゲル状洗浄剤として、例えば、特許文献1には、接着促進剤、界面活性剤、ミネラルオイルおよび水を含有した組成物が提案されており、該組成物を処理対象に塗布した際に自己接着性を示し、該組成物上を水が通過すると対象表面に湿潤膜を付与することが開示されている。また、特許文献2では、(HO-A1O)j-(A2O)k-(A3O)l-(A2O)m-(A1O)n-Hで表される特定されたポリオキシアルキレンブロックポリマー及び水を含有する、ゲル状洗浄剤組成物が提案されている。

本発明の固形洗浄剤は、便器ボウル内面の硬質表面に付着させて用いる固形洗浄剤であって、洗浄領域と接着領域とを有し、前記洗浄領域及び前記接着領域は共に、赤外吸収(IR)スペクトルにおいて波数3660~3200cm-1、3000~2840cm-1及び1150~1080cm-1に吸収極大ピークを有する。
Hereinafter, embodiments of the present invention will be described in detail.

(赤外吸収(IR)スペクトル)
本発明における洗浄領域と接着領域は共に、IRスペクトルにおいて波数3660~3200cm-1、3000~2840cm-1及び1150~1080cm-1に吸収極大ピーク(以下、単に「ピーク」と称することがある。)を有する。
(Infrared absorption (IR) spectrum)
Both the cleaning region and the adhesive region in the present invention have maximum absorption peaks at wave numbers of 3660 to 3200 cm -1 , 3000 to 2840 cm -1 and 1150 to 1080 cm -1 in the IR spectrum (hereinafter, may be simply referred to as "peaks"). Has.
固形洗浄剤において、洗浄領域と接着領域の上記特定のピークを類同させることにより本発明の効果が得られる理由については、下記のように推察される。
波数3660~3200cm-1におけるピーク3はアルコールのO-H伸縮振動に由来し、波数3000~2840cm-1におけるピーク2はアルカンのC-H伸縮振動に由来し、波数1150~1080cm-1におけるピーク1は脂肪族エーテルのC-O-C逆対称伸縮振動に由来する。
ピーク3及びピーク1は吸水性能に寄与するものであり、ピーク2は疎水性に寄与するものである。すなわち、ピーク1~ピーク3を有することにより、吸水性を示す官能基と疎水性を示す官能基とを有することとなり、これが固形洗浄剤を適正に機能させる要因と推察する。
The reason why the effect of the present invention can be obtained by assimilating the above-mentioned specific peaks of the cleaning region and the adhesive region in the solid detergent is presumed as follows.
洗浄領域と接着領域が特定のピーク(ピーク1~ピーク3)を有し、類同することにより、固形洗浄剤が流水と接触した際に、接着領域は吸水膨潤して接着力が強くなるとともに、洗浄領域も膨潤して相互の相溶性が増す。また流水との接触により洗浄領域が吸水して膨潤していくが、その際に、接着領域が保有する水分の一部が洗浄領域に移り、洗浄領域の膨潤を促進する。これにより、洗浄領域の便器ボウル内面への接着性が発現され、固形洗浄剤が便器ボウル内面から剥落するのを防ぐものと推察される。このように、本発明の固形洗浄剤は、製剤全体として便器ボウル内面に対する接着性を発現できることから、長期間にわたり使用し続けることができ、固形洗浄剤として優れた洗浄効果を長期間発揮することができる。
The cleaning area and the adhesive area have specific peaks (
本発明の固形洗浄剤は、洗浄領域と接着領域の前記特定のピークの吸光度比を類同させることにより上記効果をより顕著に得ることができる。
脂肪族エーテルのC-O-C逆対称伸縮振動に由来する波数1150~1080cm-1におけるピーク1の吸光度(P1及びP11)を基準(1)とした際、吸水性能に寄与する波数3660~3200cm-1におけるピーク3の吸光度(P3及びP13)の比(P1:P3及びP11:P13)を、洗浄領域及び接着領域のいずれにおいても0.2~0.5とすることにより、洗浄領域と接着領域の吸水性能を同程度とすることができるものと推察される。なお、吸水性能が同程度とは、接着領域の水との接触による膨潤速度と、洗浄領域の水との接触による接着性の発現速度とのバランスが適切である状態を示す。
The solid detergent of the present invention can obtain the above-mentioned effect more remarkably by assimilating the absorbance ratios of the specific peaks in the cleaning region and the adhesive region.
Wave number 3660 to 3200 cm that contributes to water absorption performance when the absorbance (P1 and P11) of
波数3000~2840cm-1付近の吸収帯(ピーク2)は疎水性に関わる部分であり、ピーク2の吸光度(P2及びP12)を、それぞれ前記P1及びP11に対してP1:P2=1:0.2~1.0及びP11:P12=1:0.2~1.0の関係を満たすことが、上記吸水性能を示す官能基とのバランス、すなわち吸水速度及び製剤のダレ防止の点からより好ましく、1:0.4~0.7の関係を満たすことがよりさらに好ましい。すなわち、P1:P2:P3とP11:P12:P13のいずれにおいても1:0.4~0.7:0.2~0.5とすることにより、固形洗浄剤をよりさらに好適に機能させることができることからよりさらに好ましい。 The absorption band (peak 2) near the wave number of 3000 to 2840 cm -1 is a part related to hydrophobicity, and the absorbance of peak 2 (P2 and P12) is set to P1: P2 = 1: 0 with respect to P1 and P11, respectively. It is more preferable to satisfy the relationship of 2 to 1.0 and P11: P12 = 1: 0.2 to 1.0 from the viewpoint of the balance with the functional group exhibiting the water absorption performance, that is, the water absorption rate and the prevention of sagging of the pharmaceutical product. , 1: It is more preferable to satisfy the relationship of 0.4 to 0.7. That is, by setting 1: 0.4 to 0.7: 0.2 to 0.5 in both P1: P2: P3 and P11: P12: P13, the solid detergent can function more preferably. It is even more preferable because it can be used.
また、洗浄領域及び接着領域はIRスペクトルにおいて、エステルのC=O結合に由来する波数1700~1600cm-1付近にピーク4を有することが吸水速度および溶解性調整の点から好ましい。ピーク4は主に疎水性に寄与するものである。
洗浄領域および接着領域のピーク4の吸光度P4及びP14は、吸光度P1及びP11に対して、それぞれP1:P4=1:0.05~0.3及びP11:P14=1:0.05~0.3の関係を満たすことが保形性と溶解性の点から好ましく、P1:P4とP11:P14のいずれにおいても1:0.05~0.2の関係を満たすことがより好ましい。

The powdered KBr is finely ground in an agate mortar, a wash area or adhesive area is added thereto, and the wash area or adhesive area and KBr are mixed so as to be well mixed. The mixing ratio of KBr to the cleaning region or the adhesive region is, for example, about 1 to 5 mg for the cleaning region or the adhesive region with respect to 50 mg of KBr. A sample for measuring tablets is prepared by tableting the obtained mixed powder.

本発明の固形洗浄剤における洗浄領域及び接着領域は前記(赤外吸収(IR)スペクトル)の特徴を有していればよい。
洗浄領域は、固形状を呈しており、実質的に水を含まないことが好ましい。ここで、「実質的に水を含まない」とは、洗浄領域を作製する際に水を意図的に含まないという意味であり、洗浄領域を作製中又は固形洗浄剤の保管中に不可避的に混入する微量の水分を含んでいても構わない。なお、洗浄領域中の水分量は、カールフィッシャー法または日局一般試験法(乾燥による恒量測定法)により測定することができる。
(Solid detergent)
The cleaning region and the adhesive region in the solid detergent of the present invention may have the above-mentioned characteristics (infrared absorption (IR) spectrum).
It is preferred that the washed area is solid and substantially free of water. Here, "substantially water-free" means that water is intentionally not contained when the cleaning area is prepared, and it is inevitable during the preparation of the cleaning area or the storage of the solid detergent. It may contain a small amount of water to be mixed. The amount of water in the washed area can be measured by the Karl Fischer method or the Japanese Pharmacopoeia general test method (constant amount measurement method by drying).
洗浄領域の吸水膨潤率(水膨潤速度)は、接着領域の膨潤速度と、洗浄領域の接着性発現速度とのバランスをより好適なものとする観点から、5~20W/W%/5分(単位)が好ましく、さらに10~20W/W%/5分(単位)がより好ましい。この場合、接着領域の吸水膨潤率(水膨潤速度)は、2~15W/W%/5分(単位)が好ましく、さらに2~10W/W%/5分(単位)がより好ましい。さらに洗浄領域の水膨潤速度は接着領域の水膨潤速度より約1.5~2.5倍速いほうが、固形洗浄剤の接着性維持の観点から好ましい。 The water absorption swelling rate (water swelling rate) of the washed area is 5 to 20 W / W% / 5 minutes (from the viewpoint of making the balance between the swelling rate of the adhesive area and the adhesive development rate of the washed area more suitable. (Unit) is preferable, and 10 to 20 W / W% / 5 minutes (unit) is more preferable. In this case, the water absorption swelling rate (water swelling rate) of the adhesive region is preferably 2 to 15 W / W% / 5 minutes (unit), more preferably 2 to 10 W / W% / 5 minutes (unit). Further, it is preferable that the water swelling rate of the cleaning region is about 1.5 to 2.5 times faster than the water swelling rate of the adhesive region from the viewpoint of maintaining the adhesiveness of the solid detergent.
洗浄領域の吸水膨潤率はHLB(Hydrophilic-Lipophilic Balance)値により調整することができる。 The water absorption swelling rate of the washed area can be adjusted by the HLB (Hydrophilic-Lipopicular Balance) value.
吸水膨潤率は下記の方法により求めることができる。
質量既知のφ90mmのガラスシャーレに各々5~10mm角の洗浄領域または接着領域の製剤を設置し、全体の質量を測定したのち常温にて常水を10mL添加し、そのまま5分放置した。5分後遊離水を完全に除去し、質量を測定し、各製剤が吸水した水分量を百分率にて算出する。
The water absorption swelling rate can be determined by the following method.
A pharmaceutical product having a washing area or an adhesive area of 5 to 10 mm square was placed on a glass petri dish having a known mass of φ90 mm, and after measuring the total mass, 10 mL of normal water was added at room temperature and left as it was for 5 minutes. After 5 minutes, the free water is completely removed, the mass is measured, and the amount of water absorbed by each pharmaceutical product is calculated as a percentage.
洗浄領域は、洗浄成分を含むが、主剤として界面活性剤を含有する洗浄性組成物から構成されることが好ましく、界面活性剤はイオン性界面活性剤(アニオン界面活性剤、カチオン界面活性剤、両性界面活性剤)でも非イオン性界面活性剤のいずれも使用可能であり、非イオン性界面活性剤を含有する洗浄性組成物から構成されることがより好ましい。ここで「主剤」とは、50質量%以上を含有する成分を言い、洗浄領域における洗浄効果を発揮する洗浄有効成分である。 The cleaning region contains a cleaning component, but is preferably composed of a cleaning composition containing a surfactant as a main agent, and the surfactant is an ionic surfactant (anionic surfactant, cationic surfactant, etc.). Either an amphoteric surfactant) or a nonionic surfactant can be used, and it is more preferable that the detergent composition is composed of a detergency composition containing the nonionic surfactant. Here, the "main agent" refers to a component containing 50% by mass or more, and is a cleaning active ingredient that exerts a cleaning effect in the cleaning region.
接着領域は、前記洗浄領域と同様、前記(赤外吸収(IR)スペクトル)に記載した特徴(特性吸収帯)を有するものを用いればよい。なお、接着領域は押圧により変形することが好ましく、固形洗浄剤が便器ボウル内面に対して接着性を発現することになる。接着領域の一形態は、洗浄領域より低い圧縮強度で変形可能であることにより接着し、また、接着領域の一形態は、便器ボウル内面に対して形状追従性を有することにより接着可能となる。 As the adhesive region, the one having the characteristics (characteristic absorption band) described in the above (infrared absorption (IR) spectrum) may be used as in the cleaning region. The adhesive region is preferably deformed by pressing, and the solid detergent exhibits adhesiveness to the inner surface of the toilet bowl. One form of the bonded area can be bonded because it can be deformed with a compressive strength lower than that of the cleaning area, and one form of the bonded area can be bonded by having shape-following property with respect to the inner surface of the toilet bowl.

接着領域は、常温において容易に接着性を有する組成物(接着性組成物)から構成されるが、IRスペクトルにおいて洗浄領域と類同するピークを有することから、洗浄領域に含まれる構成成分と同じ又は類似する成分が含まれる。すなわち、主剤として界面活性剤を含有する接着性組成物から構成されることが好ましく、非イオン性界面活性剤を含有することがより好ましい。界面活性剤は具体的には洗浄性組成物に含まれる界面活性剤と同様のものであっても、異なっていてもよい。 The adhesive region is composed of a composition (adhesive composition) that easily has adhesiveness at room temperature, but has a peak similar to that of the cleaning region in the IR spectrum, and is therefore the same as the constituent components contained in the cleaning region. Or similar components are included. That is, it is preferably composed of an adhesive composition containing a surfactant as a main agent, and more preferably containing a nonionic surfactant. Specifically, the surfactant may be the same as or different from the surfactant contained in the detergency composition.
接着性組成物は、その他に、高分子多糖類系接着成分、天然物系接着成分、合成ゴム系接着成分、樹脂系接着成分、アルキレングリコール系、POEアルキルエーテル等の他の接着成分を含んでいてもよい。

(便器ボウル内面の洗浄方法)
本発明に係る便器ボウル内面の洗浄方法は、上記固形洗浄剤を用いることを特徴とする。当該洗浄方法は、前記固形洗浄剤は洗浄領域と接着領域とを有し、前記接着領域部を便器ボウル内面に押圧することにより、前記固形洗浄剤を前記便器ボウル内面へ接着させる工程と、接着された固形洗浄剤における固形状の洗浄領域が吸水することにより接着性を発現するようになる工程とを含む。
(How to clean the inner surface of the toilet bowl)
The method for cleaning the inner surface of the toilet bowl according to the present invention is characterized by using the above-mentioned solid detergent.

例えば、前記接着領域を便器ボウル部内面と接触するように配置し、固形洗浄剤を便器ボウル内面に対して洗浄領域側から押圧することにより固形洗浄剤を接着する。押圧する際には、洗浄領域の圧縮強度より低く、かつ接着領域の圧縮強度より高い強度で押圧することが好ましい。 For example, the adhesive region is arranged so as to be in contact with the inner surface of the toilet bowl portion, and the solid detergent is adhered by pressing the solid detergent against the inner surface of the toilet bowl from the cleaning region side. When pressing, it is preferable to press with a strength lower than the compressive strength of the cleaning region and higher than the compressive strength of the adhesive region.
便器ボウル内面に付着された固形洗浄剤は、当初は接着領域で便器ボウル内面に接着し、水流との接触により接着領域および洗浄領域が吸水膨潤するにつれて洗浄領域も適切な接着性を発現した状態となる。そのため、接着領域の接着性が失われても、洗浄領域が接着領域の役割も果たすことができ、固形洗浄剤の剥落を防ぐことができる。これにより、固形洗浄剤を長期に渡って使用することができ、便器ボウル内面に対する優れた洗浄効果を長期間発揮することが可能となる。 The solid detergent adhering to the inner surface of the toilet bowl initially adheres to the inner surface of the toilet bowl at the adhesive region, and as the adhesive region and the cleaning region absorb water and swell due to contact with the water flow, the cleaning region also develops appropriate adhesiveness. Will be. Therefore, even if the adhesiveness of the adhesive region is lost, the cleaning region can also serve as the adhesive region, and the solid cleaning agent can be prevented from peeling off. As a result, the solid detergent can be used for a long period of time, and an excellent cleaning effect on the inner surface of the toilet bowl can be exhibited for a long period of time.
