Description
本発明は、手洗い用食器洗浄剤組成物に関する。 The present invention relates to a dishwashing composition for hand washing.
手洗い用食器洗浄剤には、洗浄時に豊かな泡立ちと洗浄時の泡の持続性が求められる。この起泡性／泡持続性は洗浄持続性と相関がある非常に重要な物性であり、これまで起泡性／泡持続性に優れる洗浄剤の開発が主に行われてきた。 A dishwashing agent for hand washing is required to have abundant foaming at the time of washing and the persistence of the foam at the time of washing. This foamability / foam persistence is a very important physical property that correlates with the persistence of washing, and until now, the development of a cleaning agent excellent in foamability / foam persistence has been mainly performed.
特許文献１には、スルホスクシネートを含有し、起泡性が高く洗浄力に優れた食器洗浄用に好適な洗浄剤の技術が開示されている。また、特許文献２にはジアルキルスルホスクシネート類とアミンオキシド類を含有する食器洗浄剤組成物の技術が開示され、ビルダーとして脂肪酸を含有しえることが詳細な説明に記載されている。特許文献３には、スルホコハク酸ジアルキルエステル塩と脂肪アルコールのエチレンオキシド縮合物を使用し得る液体洗剤組成物において、起泡抑制剤として脂肪酸を使用できることが記載されている。
Patent Document 1 discloses a technique of a detergent suitable for dishwashing containing sulfosuccinate, having high foamability and excellent detergency.
近年、環境負荷軽減、水資源有効利用の目的から、手洗い洗浄に用いる水の量を低減することが好ましく、食器洗浄剤で洗浄後のすすぎ水は極力低減することが望まれる。しかしながら、一般に起泡性／泡持続性に優れる洗浄剤は、すすぎを完了するためには多量の水を必要とする。従って、洗浄時には豊かな泡立ちと泡の持続性を示すが、すすぎ時には瞬時に泡が消え、少量の水ですすぎが完了する手洗い用食器洗浄剤が強く求められる。この点、特許文献１〜３では、すすぎ時の泡消えに関してはなんら考慮されていない。また、特許文献３に「起泡抑制剤」として挙げられているような消泡剤としての脂肪酸は、洗浄時において低泡性にすることを目的としており、洗浄時には非常に豊かな泡を持続的に形成することと、すすぎ時には瞬時に消泡する技術との関連を示唆するものではない。 In recent years, it is preferable to reduce the amount of water used for hand-washing and washing, and it is desired to reduce the rinse water after washing with a dishwashing agent as much as possible for the purpose of reducing environmental burden and effectively using water resources. However, detergents that are generally excellent in foamability / foam persistence require a large amount of water to complete rinsing. Accordingly, there is a strong demand for a dishwashing detergent for hand washing that exhibits abundant foaming and foam persistence during washing, but disappears instantly during rinsing and is rinsed with a small amount of water. In this respect, in Patent Documents 1 to 3, no consideration is given to the disappearance of bubbles during rinsing. In addition, the fatty acid as an antifoaming agent as listed as “Foaming Inhibitor” in Patent Document 3 is intended to make the foam low when washing, and maintains a very rich foam during washing. It does not suggest a relationship between the formation of the liquid and the technology of instant defoaming at the time of rinsing.
従って本発明の課題は、洗浄時には豊かな泡立ちと洗浄時の泡の持続性を示すが、すすぎ時には瞬時に泡が消え、少量の水ですすぎが完了する手洗い用食器洗浄剤を提供することにある。 Accordingly, an object of the present invention is to provide a dishwashing agent for hand washing that exhibits abundant foaming at the time of washing and the persistence of the foam at the time of washing, but the foam disappears instantly at the time of rinsing and is rinsed with a small amount of water. is there.

＜起泡力（初期泡量）及び泡消え性＞
表１の食器洗浄剤組成物を３．５°ＤＨ硬水で３．２質量％に希釈し、特開２００８−２６０８５２号公報の図１記載のポンプフォーマー容器に充填した。ここで、泡吐出機構には、メッシュサイズ２００／インチのメッシュが１枚装着されていた。次いで、容器上部のポンプヘッド部を３プッシュ連続して押し切ることにより、３ｇの泡を５００ｍｌのメスシリンダーの中に作製した。なお、押し切るスピードは、１プッシュあたり１秒のスピードで行なった。このとき、メスシリンダーの目盛りからその容量を記録し、初期泡量とした。起泡性はこの初期泡量で評価した。
<Foaming power (initial foam amount) and foam disappearance>
The dishwashing agent composition in Table 1 was diluted to 3.2% by mass with 3.5 ° DH hard water and filled into a pump former container described in FIG. 1 of JP-A-2008-260852. Here, a single mesh having a mesh size of 200 / inch was attached to the foam discharge mechanism. Next, 3 g of foam was produced in a 500 ml graduated cylinder by continuously pushing out the pump head at the top of the container for 3 pushes. Note that the speed of pushing out was 1 second per push. At this time, the volume was recorded from the scale of the graduated cylinder and used as the initial amount of foam. Foaming property was evaluated by this initial foam amount.
次に、メスシリンダーの上部に設置した硬水の導入手段（手製のジョウロ）を通して３．５°ＤＨ硬水を泡に１００ｍｌ添加し３０秒間放置した。この操作を、添加した硬水の合計が３００ｍｌになるまで繰り返した。最後の水を添加し、３０秒間放置した後の泡量を測定した。尚、泡消え性については、硬水３００ｍｌ添加において、次式で示す泡量変化率から求め、３００ｍｌ添加までに７０％以上になれば希釈（すすぎ）による速やかな泡消えが達成できるものと判断した。
泡量変化率（％）＝［１−（硬水３００ｍｌ添加後の泡量／初期の泡量）］×１００
Next, 100 ml of 3.5 ° DH hard water was added to the foam through a means for introducing hard water (manufactured by hand) installed at the top of the graduated cylinder and left for 30 seconds. This operation was repeated until the total amount of hard water added reached 300 ml. The final amount of water was added and the amount of foam after standing for 30 seconds was measured. In addition, about 300-ml hard water addition, it calculated | required from the foam amount change rate shown by following Formula, and if it became 70% or more by 300 ml addition, it was judged that rapid foam disappearance by dilution (rinsing) could be achieved. .
Foam amount change rate (%) = [1− (foam amount after adding 300 ml of hard water / initial foam amount)] × 100
