Description
本発明は、ビール工場、醸造工場、ジュースや清涼飲料等の飲料工場、牛乳工場、冷凍食品、レトルト食品、調味料やマヨネーズ等（以下、これらを総称して「飲料食品等」という。）の各種食品製造工場内の作業時に用いられるコンテナ、および流通における飲料食品等の搬送時に用いられるコンテナの洗浄に関する。 The present invention relates to beer factories, brewery factories, beverage factories such as juices and soft drinks, milk factories, frozen foods, retort foods, seasonings and mayonnaise (hereinafter collectively referred to as “beverage foods”). The present invention relates to a container used at the time of work in various food manufacturing factories and a cleaning of a container used at the time of transporting beverage food or the like in distribution.
従来、コンテナ用洗浄剤としては、例えば、プラスチックコンテナ表面に強固に付着すす黒ずみ汚れを浸漬或いは自動洗浄機によって除去するための界面活性剤、塩素系又は酸素系の漂白剤を主成分としたプラスチックコンテナ表面洗浄用洗浄剤組成物が特開２００５−２３１２０号公報に開示されている（特許文献１を参照）。 Conventionally, as a cleaning agent for containers, for example, a plastic mainly composed of a surfactant, a chlorine-based or oxygen-based bleaching agent for removing dark stains firmly adhering to the surface of a plastic container by immersion or an automatic cleaning machine A cleaning composition for cleaning a container surface is disclosed in JP-A-2005-23120 (see Patent Document 1).
また、脂肪族カルボン酸を用いた洗浄剤組成物としては、例えば、ＨＬＢが４〜１８のノニオン系界面活性剤、炭素数４〜１１の脂肪族モノカルボン酸塩及び／又は芳香族モノカルボン酸塩、無機又は有機アルカリビルダー及び水とからなることを特徴とする普通鋼冷延鋼板の鉱物油汚れに対する水溶性液体洗浄剤組成物が、特開平５−２２２３９７号公報に開示されている（特許文献２を参照）。 Examples of the detergent composition using an aliphatic carboxylic acid include a nonionic surfactant having 4 to 18 HLB, an aliphatic monocarboxylic acid salt having 4 to 11 carbon atoms and / or an aromatic monocarboxylic acid. A water-soluble liquid detergent composition for mineral oil stains on cold rolled steel sheets of ordinary steel, characterized by comprising a salt, an inorganic or organic alkali builder, and water is disclosed in Japanese Patent Application Laid-Open No. 5-22297 (Patent). Reference 2).
さらに、アルミニウム等の軽金属硬表面の洗浄に適した洗浄剤組成物としては、例えば、水酸化アルカリ金属化合物を主成分とし、カルシウム化合物（好ましくは水溶性カルシウム化合物）およびポリカルボン酸またはそのアルカリ金属塩の二成分を含有し、さらに必要に応じて界面活性剤を含有してなり、前記二成分の合計含有量が水酸化アルカリ金属化合物１００重量部に対して０．０１〜３０重量部であり、かつ、前記二成分の含有比率がカルシウム化合物と、ポリカルボン酸またはそのアルカリ金属塩との重量比が、１：１０〜５：１（重量部）である、アルミニウム等、軽金属硬表面の洗浄に適した高アルカリ洗浄剤組成物であつて、特に、高アルカリ性であつて、珪酸塩を含まないにもかかわらず、軽金属硬表面の防食効果を有する洗浄剤組成物が、特開２００４−５１７６１号公報に開示されている（特許文献３を参照）。 Furthermore, examples of the cleaning composition suitable for cleaning light metal hard surfaces such as aluminum include, for example, an alkali metal hydroxide compound as a main component, a calcium compound (preferably a water-soluble calcium compound), and a polycarboxylic acid or an alkali metal thereof. It contains two components of salt, and further contains a surfactant as required, and the total content of the two components is 0.01 to 30 parts by weight with respect to 100 parts by weight of the alkali metal hydroxide compound. Washing a light metal hard surface such as aluminum in which the content ratio of the two components is 1:10 to 5: 1 (parts by weight) of a calcium compound and a polycarboxylic acid or an alkali metal salt thereof. A highly alkaline detergent composition suitable for use in a metal, especially having high alkalinity and having no anti-corrosion effect on light metal hard surfaces even though it does not contain silicate. That the detergent composition is disclosed in JP-A-2004-51761 (see Patent Document 3).
しかしながら、上記特許文献１のプラスチックコンテナ表面洗浄用洗浄剤組成物は、塩素系または酸素系の漂白剤を含有するものであるため、アルミニウム等の金属に対して腐食や変色を起こしてしまうという問題を有している。また、上記特許文献２の水溶性液体洗浄剤組成物は、普通鋼冷延鋼板の鉱物油汚れに対するものであって、本件発明との技術的課題や技術的思想等を異にするものである。そして、特許文献３の防食効果を有する洗浄剤組成物では、カルシウム化合物とポリカルボン酸またはそのアルカリ金属塩とを特定比率で含有することにより軽金属硬表面の防食効果を発現させるものであるが、カルシウム化合物を含有するために、硬水下での使用におけるスケール付着抑制にやや問題を残すものとなっていた。 However, since the detergent composition for cleaning the plastic container surface of Patent Document 1 contains a chlorine-based or oxygen-based bleach, there is a problem of causing corrosion or discoloration to a metal such as aluminum. have. Moreover, the water-soluble liquid detergent composition of the above-mentioned patent document 2 is for mineral oil stains on a cold rolled steel sheet of ordinary steel, and is different from the technical problem and technical idea of the present invention. . And in the detergent composition having the anticorrosive effect of Patent Document 3, the anticorrosive effect of the light metal hard surface is expressed by containing the calcium compound and the polycarboxylic acid or the alkali metal salt thereof in a specific ratio. Since it contains a calcium compound, there has been a slight problem in suppressing scale adhesion in use under hard water.
こうした問題を解決し、ビール工場、醸造工場、ジュースや清涼飲料等の飲料工場、牛乳工場、冷凍食品、レトルト食品、調味料やマヨネーズ等（飲料食品等）の各種食品製造工場内の作業時に用いられるコンテナ、および流通における飲料食品等の搬送時に用いられるコンテナ洗浄剤組成物およびそれを用いた洗浄方法が要望されている。 To solve these problems, beer factories, brewery factories, beverage factories such as juices and soft drinks, milk factories, frozen foods, retort foods, seasonings and mayonnaise (beverage foods, etc.) used in various food manufacturing factories There is a need for a container cleaning composition, a container cleaning composition used for transporting beverage foods and the like in distribution, and a cleaning method using the same.
このため、洗浄工程およびすすぎ工程におけるスケールの析出および付着を防止し、優れた洗浄力と貯蔵安定性を有するとともにアルミニウムの腐食抑制効果を有するコンテナ用洗浄剤組成物およびそれを用いた洗浄方法の提供を目的とする。 For this reason, the deposition and adhesion of scales in the cleaning process and the rinsing process are prevented, and the cleaning composition for containers and the cleaning method using the same have excellent cleaning power and storage stability and have an effect of inhibiting corrosion of aluminum. For the purpose of provision.
