Description
本発明は、自動洗浄機用洗浄剤組成物に関する。
The present invention relates to a cleaning composition for an automatic cleaning machine.
ホテル、レストラン等においては、作業の効率化、衛生管理などの観点から、使用後の食器又は調理器具の洗浄に自動食器洗浄機等の自動洗浄機が用いられている。また、一般家庭においても、近年急速に自動洗浄機が普及している。自動洗浄機に用いられる洗浄剤組成物に求められる性能として、洗浄力が高いことに加えて、泡立ちが少ないこと(低泡性)が挙げられる。
In hotels, restaurants, etc., automatic washing machines such as an automatic dishwasher are used to wash used dishes or cooking utensils from the viewpoints of work efficiency and hygiene management. In general households, automatic washing machines have been rapidly spreading in recent years. In addition to high detergency, the performance required of a detergent composition used in an automatic washer includes low foaming (low foaming).
特許文献1には、低泡性の自動食器洗浄機用の洗浄剤組成物として、(a)非イオン界面活性剤0.1~5質量%、(b)ポリプロピレングリコール0.1~10質量%等を含有し、全界面活性剤濃度が10質量%以下であって、粘度1000~4000mPa・sの液状洗浄剤組成物が開示されている。特許文献2には、特定構造の非イオン界面活性剤(a)と、オキシプロピレン基の平均縮合度が10~90であるポリオキシプロピレン(b)とを合計で0.1~20重量%含有し、且つ(a)と(b)の重量比が(a)/(b)=1/2~1/1である自動食器洗浄機用洗浄剤組成物が開示されている。特許文献3には、オキシプロピレン基の平均縮合度が30~90であるポリオキシプロピレンを含有する自動食器洗浄機用洗浄剤組成物が開示されている。
Patent Document 1 discloses (a) 0.1 to 5% by mass of a nonionic surfactant and (b) 0.1 to 10% by mass of polypropylene glycol as a detergent composition for a low-foam automatic dishwasher. Etc., the total surfactant concentration is 10% by mass or less, and a viscosity of 1000 to 4000 mPa · s is disclosed. Patent Document 2 contains a nonionic surfactant (a) having a specific structure and a polyoxypropylene (b) having an average degree of condensation of oxypropylene groups of 10 to 90 in total of 0.1 to 20% by weight. In addition, a detergent composition for an automatic dishwasher in which the weight ratio of (a) and (b) is (a) / (b) = 1/2 to 1/1 is disclosed. Patent Document 3 discloses a cleaning composition for an automatic dishwasher containing polyoxypropylene having an average degree of condensation of oxypropylene groups of 30 to 90.
自動洗浄機は、高温(例えば、40~70℃)の洗浄液を噴射して食器等の汚れを落とすタイプのものが主流であるが、自動洗浄機の立ち上げ(運転開始)時には、洗浄液の水温は室温程度の低温である場合が多い。このように洗浄液の温度が低い場合(低温時)には、自動洗浄機用洗浄剤組成物に含まれる界面活性剤等の成分が泡立ち易い。また、洗浄液の泡立ちは、洗浄剤組成物に含まれる界面活性剤等の成分に起因するだけでなく、食器等に付着した汚れ(食品残渣等)から持ち込まれる物質によっても発生する。例えば、油汚れ、タンパク質汚れ、デンプン汚れ等の食品由来の汚れによって、泡立ちが引き起こされる。特に激しい泡立ちを引き起こすのはタンパク質汚れであり、代表的なものとして卵汚れが挙げられる。特許文献1~3の自動食器洗浄機用洗浄剤組成物は、このような低温時の泡立ちや、汚れに起因する泡立ちの抑制効果をより向上させる改善の余地があった。
また、業務用自動洗浄機では、通常家庭用自動洗浄機よりも高圧の水流で洗浄を行うため泡立ちも多く、より高い抑泡性が必要とされる。特許文献1~3の自動食器洗浄機用洗浄剤組成物は、業務用自動洗浄機で使用する場合に抑泡性が不充分であり、抑泡性をより高める改善の余地があった。 The main type of automatic washing machine is a type that sprays high temperature (for example, 40 to 70 ° C) cleaning liquid to remove dirt such as dishes, but when the automatic cleaning machine is started up (starts operation), the water temperature of the cleaning liquid Is often as low as room temperature. Thus, when the temperature of the cleaning liquid is low (at a low temperature), components such as a surfactant contained in the cleaning composition for an automatic cleaning machine tend to foam. In addition, the foaming of the cleaning liquid is caused not only by a component such as a surfactant contained in the cleaning composition, but also by a substance brought in from dirt (food residue or the like) attached to the tableware or the like. For example, fouling is caused by food-derived soils such as oil stains, protein stains and starch stains. In particular, protein fouling causes intense foaming, and typical examples include egg fouling. The detergent compositions for automatic dishwashers of Patent Documents 1 to 3 have room for improvement to further improve the effect of suppressing such foaming at low temperatures and foaming due to dirt.
In addition, the automatic cleaning machine for business use usually has a higher foam suppression because it is washed with a high-pressure water flow than the automatic cleaning machine for home use, and higher foam suppression is required. The detergent compositions for automatic dishwashers disclosed in Patent Documents 1 to 3 have insufficient foam suppression when used in commercial automatic washing machines, and there is room for improvement to further improve foam suppression.
また、業務用自動洗浄機では、通常家庭用自動洗浄機よりも高圧の水流で洗浄を行うため泡立ちも多く、より高い抑泡性が必要とされる。特許文献1~3の自動食器洗浄機用洗浄剤組成物は、業務用自動洗浄機で使用する場合に抑泡性が不充分であり、抑泡性をより高める改善の余地があった。 The main type of automatic washing machine is a type that sprays high temperature (for example, 40 to 70 ° C) cleaning liquid to remove dirt such as dishes, but when the automatic cleaning machine is started up (starts operation), the water temperature of the cleaning liquid Is often as low as room temperature. Thus, when the temperature of the cleaning liquid is low (at a low temperature), components such as a surfactant contained in the cleaning composition for an automatic cleaning machine tend to foam. In addition, the foaming of the cleaning liquid is caused not only by a component such as a surfactant contained in the cleaning composition, but also by a substance brought in from dirt (food residue or the like) attached to the tableware or the like.
