【発明の詳細な説明】 高親水性および高疎水性のノニオン性界面活性剤を組み合わせたクリーニング 組成物 技術分野 本発明は、クリーニング組成物に関する。本発明は主として硬質表面クリーニ ング組成物に適用されるものであるが、皿洗いおよび洗濯洗剤組成物などの他の クリーニング組成物に対しても興味深いものである。 背景 希釈した形態で用いることができる組成物は、当該技術分野において知られて いる。これらの組成物では、技術的問題は、希釈時に効率的なクリーニング性能 を維持することにある。希釈クリーニング用のこれらの組成物は、例えば欧州特 許EP−A−O503219号明細書に記載されている。これらの組成物では、 希釈クリーニング性能は、アルカノールアミンを用いて得られる。この′219 号特許出願明細書には、ノニオン性界面活性剤の使用も記載されており、それら の界面活性剤としてエトキシル化脂肪アルコールが挙げられている。 高エトキシル化ノニオン性界面活性剤であって、希釈形態で使用することかで きるものなどの各種の界面活性剤を含んでなる硬質表面クリーニング組成物も、 当該技 術分野において知られている。この先行技術の代表的なものは、欧州特許出願E P92870045.9号明細書に記載されている組成物である。 いくつかの点において良好な性能を有するクリーニング組成物を開発するため 、不断の努力が行なわれている。油汚れおよび石鹸滓などの総ての汚れを良好に クリーニングすることは、例えば硬質表面のクリーニングによく用いられるニー トおよび希釈組成物のいずれについても主要な目的であることは勿論である。こ のような油汚れは、通常は油および脂肪性食品で調理することにより、および人 の皮膚と単に接触することによって生じるのであり、従ってこれらはほとんどの 表面、特に浴室および台所に見られる。 従って、本発明の目的は、各種表面並びに洗濯物に希釈した形態で効果的に用 いて、各種の汚れおよび染みをクリーニングすることができるクリーニング組成 物を提供することである。更に具体的には、本発明のもう一つの目的は、硬質表 面クリーナーとして用いるときに十分な光沢性能と表面の安全性を提供すること である。 この目的は、特殊なノニオン性界面活性剤系を含んでなるクリーニング組成物 を処方することによって効率的に適えられることが判明している。実際に、HL Bが少なくとも12(親水性−親油性バランス)である少なくとも1種類の第一 のノニオン性界面活性剤と、HLBが 10を下回りかつ第一の界面活性剤のHLBより少なくとも4小さい少なくとも 1種類の第二のノニオン性界面活性剤を含んでなるクリーニング組成物は、これ がクリーニングすることができる汚れの種類に大きな柔軟性を示すことを見出し た。これらの組成物は、意外なことには、希釈時には典型的なノニオン性界面活 性剤を含んでなる組成物と比較して優れたクリーニング性能を示すが、ニート、 すなわち未希釈組成物のクリーニング性能は、前記のノニオン性界面活性剤系が 含まれていることとは無関係に同じである。 すなわち、HLBが少なくとも12である少なくとも1種類の第一の界面活性 剤と、HLBが10を下回りかつ第一の界面活性剤のHLBより少なくとも4小 さい少なくとも1種類の第二のノニオン性界面活性剤とのノニオン性界面活性剤 系を含んでなるクリーニング組成物は、ニートおよび希釈して用いるいずれの場 合にも、優れたクリーニング性能を示すことが判った。 具体的には、本発明による組成物は、硬水中で使用する場合および軟水中で使 用する場合のいずれの場合にも油汚れに特に有効である。実際に、本発明の特に 有利な点は、この製品を希釈するのに用いた水の硬度の変化などの様々な使用条 件に耐え得ることである。 本発明は、HLBが少なくとも12である少なくとも1種類の第一の界面活性 剤と、HLBが10を下回りか つ第一の界面活性剤のHLBより少なくとも4小さい少なくとも1種類の第二の ノニオン性界面活性剤との組み合わせにより、他の成分の濃度を減少させて、し かも最適クリーニング性能を保持したまま、組成物処方することができるので、 特に有用であり、また使用者は同じ仕事をするのに製品が少なくて済む。この利 点は、環境適合性に関して特に重要である。 発明の概要 本発明は、ノニオン性界面活性剤系を総組成物の重量の0.5%〜30%含ん でなる水性クリーニング組成物であって、 前記ノニオン性界面活性剤系が、 HLBが少なくとも12である第一の界面活性剤を総組成物の重量の少なくと も0.1%、 HLBが10を下回りかつ第一の界面活性剤のHLBより少なくとも4小さい 第二の界面活性剤を総組成物の重量の少なくとも0.1%含んでなる。 本発明は、前記のニート組成物および希釈組成物の両方を包含する。希釈組成 物は、ノニオン界面活性剤系を総組成物の重量の0.5%〜30%含んでなる前 記ニート組成物を水で希釈することによって得られる。この希釈組成物は、前記 ノニオン性界面活性剤系を総組成物の重量の0.001%〜5%含む。 本発明は、硬質表面のクリーニング方において、HLBが少なくとも12であ る第一の界面活性剤を総組成物の重量の少なくとも0.1%と、HLBが10を 下回りかつ第一の界面活性剤のHLBより少なくとも4小さい第二の界面活性剤 を総組成物の重量の少なくとも0.1%とを含んでなるノニオン性界面活性剤系 を含む組成物を水で希釈した後、前記硬質表面に適用することを特徴とする方法 も包含する。 発明の詳細な説明

この界面活性剤系を提供するのに好適なノニオン性界面活性剤は、市販のアル コキシル化アルコールまたはアルコキシル化フェニルアルコールであって、各種 のアルコール鎖長および各種のアルコキシル化度を有するものである。アルコー ルの鎖長および/またはアルコキシル化度を変更するだけで、異なるHLB値を 有するアルコキシル化アルコールまたはアルコキシル化フェニルアルコールを得 ることができる。任意の特定の化合物のHL B値は文献から得ることができることを当業者であれば理解すべきである。 本発明で用いられる高親水性および高疎水性のノニオン性界面活性剤を製造す るのに好適な化学的方法としては、対応するアルコールとアルキレンオキシドと を所望な割合で縮合させることが挙げられる。このような方法は当業者には周知

TECHNICAL FIELD The present invention relates to a cleaning composition. The present invention applies primarily to hard surface cleaning compositions, but is of interest to other cleaning compositions such as dishwashing and laundry detergent compositions. Background Compositions that can be used in diluted form are known in the art. With these compositions, the technical problem is to maintain efficient cleaning performance upon dilution. These compositions for dilute cleaning are described, for example, in EP-A-O503219. In these compositions, dilute cleaning performance is obtained with alkanolamines. The '219 patent application also describes the use of nonionic surfactants, including ethoxylated fatty alcohols as those surfactants. Hard surface cleaning compositions comprising various surfactants, such as highly ethoxylated nonionic surfactants that can be used in dilute form, are also known in the art. Representative of this prior art is the composition described in European patent application EP 928700455.9. There are constant efforts to develop cleaning compositions that have good performance in some respects. It goes without saying that good cleaning of all soils such as greasy soils and soap scum is a major objective for both neat and dilute compositions, which are often used for cleaning hard surfaces, for example. Such greasy stains are usually produced by cooking with oils and fatty foods and by simple contact with human skin, so they are found on most surfaces, especially bathrooms and kitchens. Accordingly, it is an object of the present invention to provide a cleaning composition that can be effectively used in a diluted form on various surfaces and laundry to clean various stains and stains. More specifically, another object of the present invention is to provide sufficient gloss performance and surface safety when used as a hard surface cleaner. It has been found that this purpose can be met efficiently by formulating a cleaning composition comprising a special nonionic surfactant system. Indeed, at least one first nonionic surfactant having an HLB of at least 12 (hydrophilic-lipophilic balance) and an HLB of less than 10 and at least 4 less than the HLB of the first surfactant. It has been found that a cleaning composition comprising at least one second nonionic surfactant exhibits great flexibility in the types of stains it can clean. Surprisingly, these compositions show superior cleaning performance when diluted, as compared to compositions comprising typical nonionic surfactants, but neat, i.e. undiluted compositions.

That is, at least one first surfactant having an HLB of at least 12, and at least one second nonionic surfactant having an HLB of less than 10 and at least 4 smaller than the HLB of the first surfactant. It has been found that the cleaning composition containing the nonionic surfactant system described above exhibits excellent cleaning performance both when used neat and when diluted. In particular, the composition according to the invention is particularly effective against oil stains both when used in hard water and when used in soft water. In fact, a particular advantage of the present invention is that it can withstand various conditions of use, such as changes in the hardness of the water used to dilute the product. The present invention relates to at least one first surfactant having an HLB of at least 12 and at least one second nonionic interface having an HLB of less than 10 and at least 4 less than the HLB of the first surfactant. The combination with an activator is particularly useful because it allows the composition to be formulated while reducing the concentration of other ingredients while still maintaining optimal cleaning performance, and also helps the user to do the same job.
