Description
本発明は、食器洗浄機用液体洗浄剤組成物に関する。 The present invention relates to a liquid detergent composition for a dishwasher.
食器洗浄機は汚れた皿、グラス、料理器具などの食器を洗浄する設備であり、家庭やレストラン、喫茶店などの厨房で使用されている。通常、食器洗浄は洗浄工程―濯ぎ工程の順で行われ、洗浄工程には手洗い用食器洗浄剤と異なる、無泡性或いは低泡性の食器洗浄機用洗浄剤が使用されている。また、レストラン、喫茶店などの厨房で使用されている業務用食器洗浄機には濯ぎ工程でリンス剤が使用されている。 A dishwasher is a facility for washing dishes such as dirty dishes, glasses and cooking utensils, and is used in kitchens such as homes, restaurants and coffee shops. In general, dishwashing is performed in the order of washing process-rinsing process. In the washing process, a non-foaming or low-foaming dishwasher cleaner different from a dishwashing detergent for hand washing is used. In addition, a rinsing agent is used in the rinsing process for commercial dishwashers used in kitchens such as restaurants and coffee shops.
これらの食器洗浄機用洗浄剤組成物には、強固な油脂汚れを落とすことを目的として、水酸化ナトリウム、水酸化カリウム、炭酸ナトリウムや炭酸カリウムなどのアルカリ剤が配合されている。水酸化ナトリウムや水酸化カリウムを５％以上含む食器洗浄機用洗浄剤組成物は、「医薬用外劇物」となり、専門的な知識や取り扱いに注意を要する。また、上記アルカリ剤を含む食器洗浄機用洗浄剤組成物は、ガラス製食器を浸食したり、アルミ製食器を黒変させたりする恐れがある。更に、飛散して皮膚に付着した場合には強い刺激性を与えたり、眼に入った場合には失明したりすることがあるため、作業者は安全のために必ず適切な手袋や保護メガネを着用しなければならない。そこで、上記アルカリ剤の代わりに油汚れに対して高い洗浄性を有する各種界面活性剤を配合した、中性タイプの食器洗浄機用洗浄剤組成物が提案されている。しかし、泡立ちが多く、ポンプを介したノズル噴射式の機械洗浄に適していないものがある。 These dishwasher cleaning compositions contain an alkaline agent such as sodium hydroxide, potassium hydroxide, sodium carbonate or potassium carbonate for the purpose of removing strong oily dirt. A detergent composition for dishwashers containing 5% or more of sodium hydroxide or potassium hydroxide becomes a “non-medical deleterious substance” and requires special knowledge and handling. Moreover, the detergent composition for tableware washing machines containing the said alkaline agent may erode glass tableware or blacken aluminum tableware. In addition, if splashed and adhered to the skin, it may cause strong irritation, and if it enters the eyes, it may cause blindness, so workers must wear appropriate gloves and protective glasses for safety. Must be worn. Then, the neutral type dishwasher detergent composition which mix | blended various surfactants which have high washing | cleaning property with respect to oil stains instead of the said alkali agent is proposed. However, there are many bubbles that are not suitable for nozzle-jet type machine cleaning via a pump.
また、強アルカリ剤とされる水酸化アルカリ金属塩の配合割合を減らして環境への負荷を低減でき、洗浄性能、低泡性と、貯蔵安定性、すすぎ後の仕上がり性に優れた液体洗浄剤組成物を提供するために、特許文献１では、アルカリ剤、金属イオン封鎖剤、アルケニルジカルボン酸ジアルカリ金属塩からなる可溶化剤、非イオン界面活性剤を特定条件で用いることを提案している。
しかしながら、特許文献１では、洗浄性能を確保するために一定量の非イオン界面活性剤を配合することを必要としており、食器洗浄機用洗浄剤に要求される低泡性を、洗浄力を維持したまま十分に得ることは困難である。 However, in Patent Document 1, it is necessary to add a certain amount of a nonionic surfactant to ensure the cleaning performance, and the low-foaming property required for the dishwasher cleaning agent is maintained while maintaining the cleaning power. It is difficult to get enough.
本発明の課題は、タンパク汚れ等に対して優れた洗浄力を有し、且つ抑泡性にも優れた食器洗浄機用液体洗浄剤組成物を提供することである。 An object of the present invention is to provide a liquid detergent composition for a dishwasher that has excellent detergency against protein stains and the like and is also excellent in foam suppression.

上記の成分は、国際公開第９９／５８６３３号パンフレットに記載されているものを参照できる。 As the above components, those described in International Publication No. 99/58633 pamphlet can be referred to.
本発明の食器洗浄機用液体洗浄剤組成物は、使用にあっては水等で適当な濃度に希釈した洗浄液として用いられることが好ましい。 The liquid detergent composition for a dishwasher of the present invention is preferably used as a cleaning liquid diluted to an appropriate concentration with water or the like.
本発明の食器洗浄機用液体洗浄剤組成物を用いた業務用食器洗浄機による洗浄の際には、該組成物は、供給装置によって業務用食器洗浄機内部に一定量任意に移送され、適正な洗浄液の濃度が維持される。食器洗浄機用液体洗浄剤組成物は、業務用食器洗浄機専用のチューブを食器洗浄機用液体洗浄剤組成物が充填されたプラスチック等の容器の中に直接差し込み吸い上げられて、業務用食器洗浄機内部へ供給される。 In the case of washing with a commercial dishwasher using the liquid detergent composition for a dishwasher of the present invention, the composition is arbitrarily transferred into a commercial dishwasher by a supply device, and is appropriately transferred. The concentration of the correct cleaning solution is maintained. The dishwasher liquid detergent composition is used for commercial dishwashing by inserting a tube dedicated to commercial dishwashers directly into a plastic container filled with the liquid detergent composition for dishwashers. Supplied inside the machine.
本発明の食器洗浄機用液体洗浄剤組成物は、洗浄液中の濃度が０．０５〜０．５重量％で使用されるが、経済性、洗浄性の観点から、０．０５〜０．３重量％が好ましく、さらに０．０５〜０．２重量％が好ましい。食器の洗浄時間は、洗浄性の観点から、１０秒〜３分が好ましく、さらに好ましくは、２０秒〜２分である。洗浄液の洗浄温度は、短時間での洗浄性を高めるためには、非常に重要で４０℃以上が好ましく、特に４０〜７０℃が好ましい。食器は洗浄された後、通常、同じ業務用食器洗浄機にて速やかに６０〜９０℃の温水で濯ぎが行われる。濯ぎは６０〜９０℃の温水のみで行うことができる。 The liquid detergent composition for a dishwasher of the present invention is used at a concentration of 0.05 to 0.5% by weight in the cleaning liquid, but from the viewpoint of economy and detergency, 0.05 to 0.3. % By weight is preferable, and 0.05 to 0.2% by weight is more preferable. The washing time for tableware is preferably 10 seconds to 3 minutes, more preferably 20 seconds to 2 minutes, from the viewpoint of detergency. The cleaning temperature of the cleaning liquid is very important for improving the cleaning performance in a short time, and is preferably 40 ° C. or more, and particularly preferably 40 to 70 ° C. After the dishes are washed, they are usually rinsed quickly with hot water at 60 to 90 ° C. in the same commercial dishwasher. Rinsing can be performed only with hot water at 60 to 90 ° C.
業務用食器洗浄機では、食器を連続洗浄する場合、洗浄液はポンプで循環させて繰り返し使用し、洗浄している。 In a commercial dishwasher, when washing dishes continuously, the cleaning liquid is circulated with a pump and repeatedly used for washing.
業務用食器洗浄機により食器を連続洗浄する場合、食器による洗浄液の持ち出しや、洗浄槽への濯ぎ水のキャリーオーバーなどによって、洗浄回数とともに洗浄液の濃度が減少する。適切な洗浄液の濃度を維持するため、自動供給装置によって適正濃度となるように食器洗浄機用液体洗浄剤組成物が供給される。 In the case of continuously washing dishes with a commercial dishwasher, the concentration of the washing liquid decreases with the number of washings due to carry-out of the washing liquid by tableware or carry-over of rinsing water to the washing tank. In order to maintain an appropriate concentration of the cleaning liquid, the liquid detergent composition for the dishwasher is supplied by the automatic supply device so as to obtain an appropriate concentration.
食器洗浄機用液体洗浄剤組成物の自動供給装置としては、特に限定されるものではないが、洗浄液の濃度をセンシングし、シグナルを受信して、チューブポンプを駆動させて、必要量の食器洗浄機用液体洗浄剤組成物を供給する。 The automatic supply device for the liquid detergent composition for a dishwasher is not particularly limited, but the concentration of the washing liquid is sensed, a signal is received, the tube pump is driven, and the required amount of dishwashing is performed. Supply the machine liquid detergent composition.
この自動供給装置は、１日の洗浄回数が非常に多い業務用には好適に用いられ、洗浄回数毎の手投入に比べ、格段に手間が省けるという利点があり、またそれ以外に、１日中（洗浄中）適正濃度を維持することが容易となる。 This automatic supply device is preferably used for business use with a very large number of cleanings per day, and has the advantage that it saves a lot of time compared to manual feeding for each cleaning frequency. It becomes easy to maintain a proper concentration in the middle (during washing).
