＜硬質表面用液体洗浄剤組成物＞
本発明の硬質表面用液体洗浄剤組成物が、本願効果を発現する理由は必ずしも定かではないが、以下の様に推定される。
イソステアリン酸等の脂肪酸は鎖式分岐炭化水素基を有し、融点が低く、常温で液体である。そのため、常温で固体の直鎖の脂肪酸と比べて、硬質表面の洗浄時のすすぎ乾燥後に凝集しにくい。またその分子構造は、かさ高い構造であり結晶構造をとりづらいことから、洗浄使用時（希釈時、又は被洗浄物の水での濯ぎ時）に洗浄設備に付着する析出物の発生（白化現象）が起こりづらい。一方、鎖式分岐炭化水素基を有する脂肪酸は、かさ高い構造を有するために、泡膜形成時に他の界面活性剤も含めて分子集合するとき、気液界面での分子配列が乱れパッキング性を低下させることから、排液が促進するため気泡の安定性が損なわれる。その結果、液体洗浄剤組成物に圧力をかけて発泡する際に泡形成量が不足し発泡連続性が発現しない。そこで、本発明においては、鎖式分岐炭化水素基を有するカルボン酸と水溶性高分子化合物を併用する。水溶性高分子化合物は水中に分散しているとき水和しており、気泡間の液膜中において多量の水分子を捕捉することができる。これにより、気液界面での界面活性剤が構成する膜構造のパッキングが疎であっても排液が起こりにくく、安定な気泡が形成され発泡連続性が発現されるものと考えられる。また、水溶性高分子化合物は、すすぎ水中の硬度成分（金属イオン）を捕捉するキレート能を有することが予測され、鎖式分岐炭化水素基を有するカルボン酸の塩形成を阻害することにより白化抑制性にも寄与していると考えられる。
尚、本発明の効果は上記作用機構に制限されるものではない。
<Liquid cleaning composition for hard surfaces>
The reason why the liquid detergent composition for hard surfaces of the present invention exerts the effect of the present application is not always clear, but it is presumed as follows.
Fatty acids such as isostearic acid have chain branched hydrocarbon groups, have a low melting point, and are liquid at room temperature. Therefore, as compared with linear fatty acids that are solid at room temperature, they are less likely to aggregate after rinsing and drying when washing a hard surface. In addition, since its molecular structure is bulky and it is difficult to obtain a crystal structure, the occurrence of precipitates (whitening phenomenon) that adhere to cleaning equipment during cleaning (when diluted or when rinsed with water) ) Is hard to happen. On the other hand, a fatty acid having a chain-branched hydrocarbon group has a bulky structure, and therefore, when molecules are aggregated together with other surfactants during the formation of a foam film, the molecular arrangement at the gas-liquid interface is disturbed and packing property is reduced. Since it lowers, the drainage is promoted and the stability of the bubbles is impaired. As a result, when the liquid detergent composition is foamed under pressure, the amount of foam formation is insufficient and foaming continuity does not appear. Therefore, in the present invention, a carboxylic acid having a branched branched hydrocarbon group and a water-soluble polymer compound are used in combination. The water-soluble polymer compound is hydrated when dispersed in water, and can trap a large amount of water molecules in the liquid film between bubbles. It is considered that, as a result, even if the packing of the film structure formed by the surfactant at the gas-liquid interface is sparse, drainage is unlikely to occur, stable bubbles are formed, and foaming continuity is exhibited. Further, the water-soluble polymer compound is expected to have a chelating ability to capture the hardness component (metal ion) in the rinse water, and inhibits the whitening by inhibiting the salt formation of the carboxylic acid having a branched chain hydrocarbon group. It is considered that it also contributes to sex.
The effect of the present invention is not limited to the above-mentioned action mechanism.

Alternatively, the liquid detergent composition for hard surfaces is placed in a dedicated container, directly connected to tap water with a hose or the like, mixed while diluting, and sprayed in the form of foam. A combination of the above-mentioned pre-dilution and co-dilution can also be used to spray a dilute solution of the liquid detergent composition for hard surfaces in the form of foam. The dilution ratio in step 1 is 2 to 200 times, preferably 5 to 200 times, and more preferably 20 to 100 times.
Here, the water used for dilution is generally assumed to be water containing a hardness component, such as tap water.

Here, "injecting without interruption" means, for example, that the cleaning agent is continuously foamed (for example, 5 seconds or longer) while being opened by a lever or a switch using a foam cleaning machine. Represents continuous injection, which is an "intermittent" injection, for example, when a lever is pulled using a hand sprayer such as a trigger sprayer or a former player, and the injection stops instantaneously. Distinguished from the mode of injection.
泡洗浄機を用いて間欠することなく泡状に噴射する態様は、洗浄対象である食品加工設備及び／又は調理設備の面積や規模が大きい場合により有効である。 The mode in which bubbles are continuously ejected using a bubble cleaning machine is more effective when the area or scale of the food processing facility and/or cooking facility to be cleaned is large.

工程１において本発明の硬質表面用液体洗浄剤組成物の希釈溶液を泡状に噴射し食品加工設備及び／又は調理設備に付着させてから一定時間泡を保持する（工程２）。工程２において泡を保持する時間は、各装置の機構および作業性の観点から、好ましくは１〜６０分、より好ましくは１〜４５分であることが好適である。更に、１〜３０分であることが好ましく、１〜２０分であることがより好ましく、１〜１５分であることがより好ましく、１〜１０分であることがより好ましく、１〜５分であることがより更に好ましい。また、工程２において泡を保持する時間は、洗浄性の観点から、１０〜６０分であることが好ましく、１５〜４５分であることがより好ましく、２０〜３０分であることが更に好ましい。 In step 1, the diluted solution of the liquid detergent composition for hard surfaces of the present invention is sprayed in the form of foam to adhere to food processing equipment and/or cooking equipment, and then the foam is held for a certain period of time (step 2). From the viewpoint of the mechanism and workability of each device, the time for holding the bubbles in step 2 is preferably 1 to 60 minutes, more preferably 1 to 45 minutes. Furthermore, it is preferably 1 to 30 minutes, more preferably 1 to 20 minutes, more preferably 1 to 15 minutes, more preferably 1 to 10 minutes, and 1 to 5 minutes.

In addition, the time for holding the bubbles in step 2 is preferably 10 to 60 minutes, more preferably 15 to 45 minutes, and further preferably 20 to 30 minutes from the viewpoint of detergency.
工程２において泡を保持する時間は、希釈溶液の希釈倍率や使用場面によって異なり、特に制限されるものではないが、例えば２〜５０倍（好ましくは５〜５０倍）の希釈倍率では、泡を保持する時間は１〜６０分、また、５０〜２００倍の希釈倍率においては、１〜１０分の間泡を安定に保持することが好ましい。 The time for holding the bubbles in step 2 varies depending on the dilution ratio of the diluted solution and the use situation and is not particularly limited, but for example, at a dilution ratio of 2 to 50 times (preferably 5 to 50 times), the bubbles are kept. The holding time is 1 to 60 minutes, and it is preferable to hold the bubbles stably for 1 to 10 minutes at a dilution ratio of 50 to 200 times.
工程２において泡を保持している間は放置しておくことが好ましいが、僅かの水等を加えるようなことも可能である。 Although it is preferable to leave the bubbles in the step 2 while they are held, it is possible to add a small amount of water or the like.
泡を一定時間保持した後、工程３において、食品加工設備及び／又は調理設備を水で濯ぐ。濯ぎ水の温度は、好ましくは１０〜７０℃、より好ましくは２０〜７０℃であることが好適である。濯ぎ水としては、水道水を用いることができ、上記の好ましい水温に調整すべく加熱して用いてもよい。一般的には、ホース等で人の手による濯ぎ作業が行われる。本発明の硬質表面用液体洗浄剤組成物は、かかる濯ぎ時の泡切れ性に優れ、従来の洗浄剤組成物に比し、必要となる濯ぎ水が少量でよく、経済的に有利であり、また作業負荷（作業時間や作業人員数）や環境負荷の軽減にも著しく寄与するものである。 After holding the foam for a certain period of time, in step 3, the food processing facility and/or the cooking facility are rinsed with water. The temperature of the rinsing water is preferably 10 to 70°C, more preferably 20 to 70°C. Tap water can be used as the rinsing water, and the rinsing water may be heated and used to adjust to the preferable water temperature. In general, rinsing work is performed manually with a hose or the like. The liquid detergent composition for hard surfaces of the present invention has excellent defoaming properties during such rinsing, and requires less rinsing water than conventional detergent compositions, which is economically advantageous, It also significantly contributes to the reduction of work load (work time and number of workers) and environmental load.

（１）白化抑制性評価
調製した各硬質表面用液体洗浄剤組成物を、硬度２０°ｄＨの硬度水で希釈して、硬質表面用液体洗浄剤組成物の濃度が１質量％の希釈液を作製した。この希釈液を、光路長１ｃｍの石英セルに入れて、吸光光度計（株式会社日立製作所製、Ｕ-３３００）にて、６
００ｎｍの吸光度（ａｂｓ）を測定（２５℃）した。この評価では、吸光度が大きい程、硬度水中に含まれるカルシウムと組成物中に含まれる脂肪酸が結びついて脂肪酸カルシウム塩が生成され、白濁していることを意味しており、吸光度が小さい程、白化抑制性に優れていることが言える。結果を表１に示す。
(1) Evaluation of whitening suppression property Each of the prepared liquid detergent compositions for hard surfaces was diluted with hardness water having a hardness of 20° dH to prepare a diluted solution having a concentration of the liquid detergent composition for hard surfaces of 1% by mass. It was made. This diluted solution was placed in a quartz cell having an optical path length of 1 cm, and the diluted solution was measured with an absorptiometer (U-3300 manufactured by Hitachi, Ltd.).
The absorbance (abs) at 00 nm was measured (25° C.). In this evaluation, as the absorbance is higher, it means that the calcium contained in the hardness water and the fatty acid contained in the composition are bound to each other to form a fatty acid calcium salt, which is cloudy. It can be said that the inhibitory properties are excellent. The results are shown in Table 1.
（２）発泡連続性評価

〇：発泡機中の混合液が無くなるまで、発泡が途切れずに連続発泡することができた。
×：発泡機中の混合液の残量がある状態で、連続発泡操作中に発泡が途切れた。
