【発明の属する技術分野】
本発明は、洗浄剤組成物に関し、詳しくは、必要な稠度を有する液体洗浄剤組成物及びその製造方法に関する。
【0002】
【従来の技術】
洗浄剤組成物は、消費者の使い易さを考慮し、また、不溶性固形物を含有する場合には組成物の分散安定性を考慮した上で、系を適度に増粘させる必要性が生じる場合がある。
【0003】
従来の増粘法としては、異種の界面活性剤(例えば両性界面活性剤と陰イオン界面活性剤)を混合して錯体を形成させることにより粘度を出す方法、及び増粘剤を使用する方法の2点が挙げられる。
【0004】
このうち前者では、界面活性剤含有量が高くなる傾向があり、又、主剤とする界面活性剤の種類によっては、非常に増粘させ難い洗浄剤組成物もある。このような例として、ポリオキシエチレンスルホコハク酸ラウリル二ナトリウム、ココイル−L−グルタミン酸モノトリエタノールアミン、ポリオキシエチレンラウリルエーテル酢酸ナトリウム等を主剤とする洗浄剤組成物が挙げられる。これらの難増粘性の界面活性剤及びそれらの配合物には一般に低刺激性とされるものが多く、様々な用途への使用が期待されるが、他の界面活性剤と組み合わせても望ましい粘度が出にくい場合が多い。
【0005】
一方、増粘剤を使用する方法では、得られる効果は増粘剤の性能次第であるが、比較的低濃度で粘稠な洗浄剤組成物を得ることができる。
【0006】
洗浄剤組成物に使用する増粘剤に要求される重要な性質は、用途により異なるが、一般に、添加により起泡性、使用感、低温安定性、洗浄性といった粘度以外の性能に悪影響を及ぼさないこと、低刺激性であること、少量添加で効果が得られること、物理化学的に安定であること、安価であること等である。
【0007】
従来より知られる増粘剤としては、ヒドロキシメチルセルロース、ヒドロキシエチルセルロース、カルボキシメチルセルロース、カチオン化セルロース、ポリビニルアルコール、ポリアクリル酸ナトリウム、澱粉、キサンタンガム等の高分子系増粘剤、低HLBのポリオキシエチレンアルキルエーテル、ヤシ油脂肪酸ジエタノールアミド、ポリエチレングリコールジステアリン酸エステル、複数の疎水基を有するポリエーテル型の増粘剤等のノニオン界面活性剤型増粘剤がある。又、塩化ナトリウム、硫酸ナトリウム等の無機塩類も主剤とする界面活性剤の種類によっては優れた増粘効果を示す。
【0008】
しかし、高分子系増粘剤は一般的に、電解質の存在で増粘効果が損なわれる、曳糸性がでる、組成によっては均一に溶解しない場合がある、経時的に粘度が変化する、高価である等の欠点を有することが多い。又、低HLBのポリオキシエチレンアルキルエーテルは多量に添加した場合低温安定性が損なわれる、脂肪酸ジエタノールアミドは多量に添加しないと増粘しない、多量に添加するとぬるつきが出る、ニトロソアミンの問題がある、ポリエチレングリコールジステアリン酸エステルは加水分解の問題がある、無機塩は増粘効果を示す界面活性剤が限られている、多量に添加すると低温安定性が損なわれる、等の欠点がそれぞれの増粘剤にある。
【0009】
一方、複数の疎水基を有するポリエーテル型の増粘剤にはこれらの問題が少なく、汎用的な増粘剤としての使用が期待でき、特開平1−138297、特公平1−49311にも界面活性剤水溶液に対する有用性が示されている。しかし、増粘効果は未だ不十分であり、高分子系増粘剤と比較すると、増粘剤の添加量が多くなる傾向にある。
【0010】
以上の理由により、洗浄剤組成物に適度な粘性を付与するには、界面活性剤濃度を高める、増粘が容易な界面活性剤を選択する、増粘剤を多量に添加する等、配合上の制約が多く、又、洗浄剤組成物の粘性を重視するあまりに、起泡性、使用感、低温安定性、洗浄性等の他の性能が犠牲になる場合もあった。
【0011】
又、特開平10−259112には、一般式R1−(OCH2CH2)n−OR2[式中R1及びR2は炭素数5〜24のアルキル基、nは1〜9の数を示す。]で表わされる化合物を油性基剤として化粧料組成物に配合することが記載されているが、低粘度の組成物を得ることを目的としており、増粘効果については開示されていない。
【0012】
このような背景から、少量添加で良好な増粘効果を示し、且つ物理化学的にも安定な増粘剤を含有する洗浄剤組成物の開発が熱望された。
【0013】
【発明が解決しようとする課題】
本発明は、増粘効果が高く、物理化学的にも安定な増粘剤を含有する洗浄剤組成物及びその製造方法を提供することを目的とする。
【0014】
【課題を解決するための手段】
本発明者らは、このような事情に鑑み、鋭意研究の結果、ポリエーテル型増粘剤のうち、特定のアルキル(又はアルケニル)鎖長及び特定のエチレンオキシド付加モル数を有するものが、界面活性剤水溶液に対する高い増粘効果をもち、物理化学的にも安定であり、これを含有することにより、洗浄剤組成物の粘度を有効に上げることができることを見いだし、かかる知見に基づいて本発明を完成するに至った。
【0015】
即ち、本発明の洗浄剤組成物は、一般式(1)
R1−O−(EO)a−R2 (1)
[式中、R1、R2は同一又は異なって、炭素数12〜28のアルキル基又はアルケニル基を示す。EOはオキシエチレン基を表し、aはエチレンオキシドの平均付加モル数であり、50〜100を示す。]

【0016】
更に効果を高めるために、任意成分として、一般式(2)

[式中、R3は炭素数8〜14のアルキル基を表す。EOはオキシエチレン基を表し、bはエチレンオキシドの平均付加モル数であり、0.5〜5を示す。]

【0021】
R1及びR2は直鎖であっても分枝鎖であっても良く、又、R1とR2は同一であっても異なっていても良い。
【0022】

BACKGROUND OF THE INVENTION
The present invention relates to a cleaning composition, and more particularly to a liquid cleaning composition having a required consistency and a method for producing the same.
[0002]
[Prior art]
The detergent composition needs to increase the viscosity of the system appropriately in consideration of ease of use by consumers, and in the case of containing insoluble solids, in consideration of the dispersion stability of the composition. There is a case.
[0003]
Conventional thickening methods include a method of increasing viscosity by mixing different types of surfactants (for example, amphoteric surfactant and anionic surfactant), and a method using a thickener. There are two points.
[0004]
Among these, the former has a tendency that the surfactant content tends to be high, and depending on the type of surfactant used as the main agent, there is a cleaning composition that is very difficult to increase in viscosity. Examples thereof include a detergent composition mainly composed of disodium polyoxyethylene sulfosuccinate lauryl, cocoyl-L-glutamate monotriethanolamine, sodium polyoxyethylene lauryl ether acetate and the like. Many of these low-viscosity surfactants and their blends are generally hypoallergenic and are expected to be used in a variety of applications, but are desirable in combination with other surfactants. Is often difficult to produce.
[0005]
On the other hand, in the method using a thickener, the effect obtained depends on the performance of the thickener, but a viscous detergent composition can be obtained at a relatively low concentration.
[0006]
The important properties required for thickeners used in cleaning compositions vary depending on the application, but in general, the addition adversely affects performance other than viscosity, such as foamability, feeling of use, low temperature stability, and cleanability. It is not irritating, has low irritation, is effective when added in a small amount, is physicochemically stable, is inexpensive, and the like.
[0007]
Conventionally known thickening agents include hydroxymethylcellulose, hydroxyethylcellulose, carboxymethylcellulose, cationized cellulose, polyvinyl alcohol, sodium polyacrylate, starch, xanthan gum, and other polymer thickeners, and low HLB polyoxyethylene alkyl. There are nonionic surfactant type thickeners such as ether, coconut oil fatty acid diethanolamide, polyethylene glycol distearate, polyether type thickener having a plurality of hydrophobic groups. In addition, an excellent thickening effect is exhibited depending on the type of the surfactant which is mainly composed of inorganic salts such as sodium chloride and sodium sulfate.
[0008]
However, polymeric thickeners generally have a thickening effect that is impaired in the presence of an electrolyte, spinnability, may not dissolve uniformly depending on the composition, change in viscosity over time, and expensive. Often has drawbacks such as Also, low-HLB polyoxyethylene alkyl ethers lose stability at low temperatures when added in large amounts, fatty acid diethanolamides do not thicken unless added in large amounts, and when added in large amounts, there is a problem of nitrosamine. Polyethylene glycol distearate has a problem of hydrolysis, inorganic salts have limited surfactants that have a thickening effect, and low temperature stability is impaired when added in large amounts. It is in the agent.
[0009]
On the other hand, polyether-type thickeners having a plurality of hydrophobic groups have few of these problems, and can be expected to be used as general-purpose thickeners. Also, JP-A-1-138297 and JP-B-1-49311 are interfaced. The utility for aqueous activator solutions has been demonstrated. However, the thickening effect is still insufficient, and the amount of thickener added tends to be larger than that of the polymer thickener.
[0010]
For the above reasons, in order to impart an appropriate viscosity to the cleaning composition, it is necessary to increase the concentration of the surfactant, select a surfactant that is easy to thicken, add a large amount of thickener, etc. In other cases, too much emphasis is placed on the viscosity of the cleaning composition, and other performances such as foaming property, feeling of use, low temperature stability, and cleaning properties may be sacrificed.
[0011]

[0012]
From such a background, the development of a cleaning composition containing a thickening agent which shows a good thickening effect when added in a small amount and which is also physicochemically stable has been eagerly desired.
