Description
本発明は、リンス剤を使用することなく、汚れの除去と同時に食器の乾燥を速める効果を有する食器洗浄機用洗浄剤組成物に関し、更に詳しくは、特定の界面活性剤を使用することにより、洗浄後のリンス効果に優れ、且つ起泡による洗浄阻害及びリンス効果の低下を生じない食器洗浄機用洗浄剤組成物に関する。 The present invention relates to a dishwasher cleaning composition having an effect of accelerating the drying of tableware simultaneously with the removal of dirt without using a rinse agent, and more specifically, by using a specific surfactant, The present invention relates to a detergent composition for a dishwasher that is excellent in rinsing effect after washing and does not cause washing inhibition due to foaming and deterioration in rinsing effect.
食器洗浄機には家庭用と業務用が知られているが、そこに使用される洗浄剤にはいずれも強力な洗浄力が要求されている。特に、業務用食器洗浄機には、洗浄以外にも食器の仕上がり性を向上させる効果が要求されている。
業務用食器洗浄機が使用される場所は、主に外食産業等の厨房であるが、こうした場所では洗浄後の食器の後片付け等における効率化や洗浄後のガラス製品の仕上がり性向上のために、洗浄後の食器がすぐに乾く速乾性の効果（リンス効果）が要求されている。一般的にリンス効果を発揮させるためにはリンス剤と呼ばれる薬剤が用いられ、通常、濯ぎ工程においてリンス剤が使用されてきた。リンス剤は食器の乾燥を速め、更にウォータースポットと呼ばれる白斑を低減して食器を美観よく仕上げることができる。しかし、食器洗浄機にリンス剤専用の供給装置を取り付けなければならず、更に、リンス剤の購入費、在庫管理費等の費用が必要となる。
また、リンス剤を直接洗浄剤に配合すれば、洗浄剤とリンス剤を別々に配合することがなく、リンス剤供給装置の必要もなくなるが、洗浄剤とリンス剤を併用すると、リンス効果が得られず、更に、洗浄剤のアルカリ成分でリンス剤が分解して逆に悪影響を及ぼすこともあり、今までのリンス剤は洗浄剤に直接配合することはできなかった。
Dishwashers are known for home use and for commercial use, but the cleaning agents used therein are required to have a strong cleaning power. In particular, commercial dishwashers are required to have an effect of improving the finish of tableware in addition to washing.
The places where commercial dishwashers are used are mainly in the kitchen of the restaurant industry, etc., but in these places, in order to improve the efficiency of cleaning up the tableware after washing and improving the finish of glass products after washing, There is a demand for a quick-drying effect (rinse effect) that allows the dishes after washing to dry quickly. In general, in order to exert a rinsing effect, a medicine called a rinsing agent is used, and a rinsing agent has been usually used in a rinsing step. The rinsing agent accelerates the drying of the tableware, and further reduces the white spots called water spots, so that the tableware can be finished aesthetically. However, it is necessary to attach a supply device dedicated to the rinse agent to the dishwasher, and further, expenses such as the purchase cost of the rinse agent and the inventory management cost are required.
Also, if the rinse agent is blended directly into the cleaning agent, the cleaning agent and the rinse agent are not blended separately, and there is no need for a rinse agent supply device. However, when the cleaning agent and the rinse agent are used in combination, a rinsing effect is obtained. In addition, the rinse agent may be decomposed by the alkaline component of the cleaning agent to adversely affect the rinsing agent, so that the conventional rinsing agent cannot be directly incorporated into the cleaning agent.
このような背景から、近年では洗浄剤にリンス効果をもたせたリンス剤不要の洗浄剤や、リンス効果を与えるような洗浄方法が開発されている。例えば、特許文献１には、洗浄及びすすぎのいずれにも非イオン性リンス剤組成物を含有する洗浄組成物を使用する食器類洗浄方法であり、前記方法は以下の（ａ）（ｂ）工程を含み、（ａ）食器類を、自動食器洗浄機内で、水性洗浄組成物と接触させ、前記水性洗浄組成物は主成分である水性希釈液及び重量にして水生希釈液１００万部あたり２５０〜３０００部のアルカリ性食器洗浄洗剤を含み、前記洗剤は、（ｉ）１０〜６０重量％の炭酸ナトリウム及び（ｉｉ）特定の非イオン性界面活性剤を含むリンス剤組成物２０〜４０重量％を含み、（ｂ）水性残留物を除去する目的で、前記洗浄済み食器類を飲用水水性リンスと接触させ、前記水性リンスは、意図的に添加されるリンス剤を実質的に含んでおらず、前記アルカリ性食器洗浄洗剤が前記飲用水水性リンス中で適度な被覆作用を得る上で十分な非イオン性界面活性剤を含有する食器類洗浄方法が開示されている。
また、特許文献２には、界面活性剤を含有する洗剤組成物を使用した食器洗浄方法であって、（ａ）自動、業務用食器洗浄機中で、食器と水性洗浄組成物とを接触させる洗浄工程であって、該水性洗浄組成物は、主成分の水性希釈剤と該水性希釈剤１００万部当たり 約２００〜５０００重量部の食器洗浄洗剤とを含んでおり、該洗剤は１５重量％を超えない量で存在する界面活性剤を含んでいる洗浄工程；及び（ｂ）前記洗浄された食器と飲用水性リンスとを接触させるすすぎ工程であって、該水性リンスは意図的に添加されたリンス剤を実質的に含んでいないすすぎ工程を有しており、前記食器洗浄洗剤は、該食器上に界面活性剤の層を提供するのに十分な吸着性界面活性剤を含有しており、前記飲用水性すすぎ工程において被覆作用を提供することを特徴とする食器洗浄方法が開示されている。
Against this background, in recent years, a cleaning agent that does not require a rinsing agent that has a rinsing effect and a cleaning method that provides a rinsing effect have been developed. For example, Patent Document 1 discloses a tableware cleaning method using a cleaning composition containing a nonionic rinse agent composition for both cleaning and rinsing. The method includes the following steps (a) and (b): (A) the dishware is brought into contact with an aqueous cleaning composition in an automatic dishwasher, the aqueous cleaning composition being an aqueous diluent and weight of the main component, 250 to 100 parts per million aquatic dilutions 3000 parts alkaline dishwashing detergent, said detergent comprising 20-40% by weight of a rinse composition comprising (i) 10-60% by weight sodium carbonate and (ii) certain nonionic surfactants (B) contacting the washed dishes with a potable water rinse for the purpose of removing an aqueous residue, the aqueous rinse being substantially free of an intentionally added rinse agent; Alkaline dishwashing There tableware cleaning method contains sufficient nonionic surfactant in obtaining adequate sheeting action in the potable water aqueous rinse in is disclosed.
Patent Document 2 discloses a dishwashing method using a detergent composition containing a surfactant, wherein (a) the tableware is brought into contact with the aqueous cleaning composition in an automatic and commercial dishwasher. A washing step, wherein the aqueous cleaning composition comprises a main component aqueous diluent and about 200-5000 parts by weight of a dishwashing detergent per million parts of the aqueous diluent, the detergent being 15% by weight A cleaning step comprising a surfactant present in an amount not exceeding; and (b) a rinsing step for contacting the cleaned tableware with a potable aqueous rinse, said aqueous rinse being added intentionally A rinsing step substantially free of rinsing agent, wherein the dishwashing detergent contains sufficient adsorptive surfactant to provide a layer of surfactant on the tableware Providing a covering action in the drinking water rinsing process. Disclosed is a method for washing dishes.
しかしながら、上記特許文献に開示されているような洗浄組成物を用いた場合、リンス効果を高めようとすると泡立ちが過剰となり洗浄性能が低下したり、逆に抑泡しようとするとリンス効果が低下するといった問題が生じ、両性能を両立することが難しかった。 However, when a cleaning composition as disclosed in the above-mentioned patent document is used, if it is attempted to increase the rinsing effect, foaming becomes excessive and the cleaning performance deteriorates, and conversely, if the foaming suppression is attempted, the rinsing effect decreases. It was difficult to achieve both performances.
従って、本発明が解決しようとする課題は、リンス剤を使用せずに、高い洗浄効果とリンス効果の２つの効果を併せ持つ食器洗浄機用の洗浄剤組成物を提供することにある。 Therefore, the problem to be solved by the present invention is to provide a cleaning composition for a dishwasher having both a high cleaning effect and a rinsing effect without using a rinsing agent.

It is preferable to dilute to 0.005-0.2 mass% is more preferable, and 0.01-0.1 mass% is more preferable. If the amount is less than 0.001% by mass, the cleaning effect and the rinse effect may not be obtained.
