Description
本発明は、デンプン、タンパク質、油脂等の汚れに対して優れた洗浄性を有し、かつ、油脂汚れに対する再汚染防止性にも優れた食器用液体洗浄剤組成物及びこれを用いた食器の洗浄方法に関する。 INDUSTRIAL APPLICABILITY The present invention is a liquid detergent composition for tableware having excellent detergency against stains such as starch, protein, oil and fat, and also excellent anti-contamination property against oil and fat stains, and tableware using the same. Regarding the cleaning method.
従来、学校、病院、社員食堂、給食施設等の大規模な調理施設では、食器類の下膳から洗浄までに時間を要するため、デンプンやタンパク質などの汚れが固着して除去し辛くなる。このため、自動食器洗浄機を用いて洗浄を行う前に食器類を浸漬用洗浄剤に浸漬して、前洗いを行うことが一般的である。また、近年では食器を浸漬する方法に代わって洗浄剤をスプレーして食器表面に泡状に吹き付けて、長時間接触させることで汚れを落とす発泡性の洗浄剤も利用されている。
しかしながら、前洗い用の浸漬液中の油脂汚れや前洗い後の自動食器洗浄中の洗浄庫内の油脂汚れによって食器類が再汚染されてしまうという問題があった。
Conventionally, in large-scale cooking facilities such as schools, hospitals, employee cafeterias, and school lunch facilities, it takes time from the bottom of the tableware to washing, so that stains such as starch and protein adhere and are difficult to remove. For this reason, it is common to immerse the tableware in a cleaning agent for immersion and perform pre-washing before washing using an automatic dishwasher. Further, in recent years, instead of the method of immersing the tableware, an effervescent cleaning agent that removes stains by spraying a cleaning agent on the surface of the tableware in the form of foam and contacting the tableware for a long time has also been used.
However, there is a problem that tableware is recontaminated by oil and fat stains in the immersion liquid for pre-washing and oil and fat stains in the washing cabinet during automatic dish washing after pre-washing.
従来の食器の浸漬洗浄に用いる洗浄剤としては、特許文献１には洗剤組成物の１０％水溶液のｐＨが４～１２であることを条件として、双性イオン高分子泡安定剤、洗浄界面活性剤および、残部としての担体およびその他の補助成分を含んでなる手皿洗用に適する洗剤組成物が記載されている。特許文献２にはポリオキシエチレンポリオキシプロピレンアルキルエーテル、デンプン分解酵素、酵素安定化剤、可溶化剤、及びｐＨ調整剤を含有することを特徴とする前浸漬用洗浄剤組成物が記載されている。特許文献３にはポリオキシエチレンアルキルエーテルと、アニオン界面活性剤を含有する機械洗浄前洗い用食器洗浄剤組成物が記載されている。
食器表面に泡状にスプレーして吹き付ける発泡性の洗浄剤としては、特許文献４には分岐鎖炭化水素基を有するアニオン界面活性剤、炭素数２以上１２以下のグリコール系溶剤、及び水を含有する食器用液体洗浄剤組成物が記載されている。
As a cleaning agent used for soaking and cleaning conventional tableware, Patent Document 1 states that a zwitterionic polymer foam stabilizer and a cleaning surface activity are used, provided that the pH of a 10% aqueous solution of the detergent composition is 4 to 12. Detergent compositions suitable for hand dishwashing comprising the agent and the carrier as a residue and other auxiliary ingredients are described. Patent Document 2 describes a pre-soaking detergent composition containing a polyoxyethylene polyoxypropylene alkyl ether, a starch degrading enzyme, an enzyme stabilizer, a solubilizer, and a pH adjuster. There is. Patent Document 3 describes a dishwashing agent composition for machine washing pre-washing containing a polyoxyethylene alkyl ether and an anionic surfactant.
Patent Document 4 contains an anionic surfactant having a branched chain hydrocarbon group, a glycol solvent having 2 or more and 12 or less carbon atoms, and water as an effervescent detergent that is sprayed and sprayed on the surface of tableware in the form of bubbles. A liquid detergent composition for tableware is described.
しかしながら、特許文献１～４に記載の組成物は何れも浸漬洗浄中の食器に油脂汚れが接触すると再汚染されるため、再汚染防止効果が十分ではなかった。また、引用文献３及び４に記載の組成物は油脂汚れに対して十分な洗浄性を発揮するが、デンプン、タンパク質に対する洗浄性は十分とは言えなかった。 However, all of the compositions described in Patent Documents 1 to 4 are not sufficiently effective in preventing recontamination because they are recontaminated when oil and fat stains come into contact with the tableware being washed by immersion. Further, although the compositions described in Cited Documents 3 and 4 exhibit sufficient detergency against oil and fat stains, they cannot be said to have sufficient detergency against starch and protein.
本発明は上記問題に鑑みなされたものである。即ち、本発明の目的は、油脂、デンプン、タンパク質に対して優れた洗浄性を有し、油脂汚れに対して優れた再汚染防止効果を発揮する食器用液体洗浄剤組成物を提供することにある。 The present invention has been made in view of the above problems. That is, an object of the present invention is to provide a liquid detergent composition for tableware which has excellent detergency against fats and oils, starch and proteins and exhibits an excellent anti-recontamination effect against greasy stains. be.
