Abstract
Description
本発明は、洗浄剤用増粘剤に関し、更に詳しくはN−アシルメチルタウリン塩等の難増粘性のアニオン界面活性剤を主基剤として含有する洗浄剤に適度な粘度を付与することができる増粘剤に関するものである。 The present invention relates to a thickener for a cleaning agent, and more specifically, it is possible to impart an appropriate viscosity to a cleaning agent containing a hardly thickening anionic surfactant such as N-acylmethyltaurine salt as a main base. It is about thickeners.
N−アシルメチルタウリン塩やアミノ酸系界面活性剤を主基剤とする液体洗浄剤組成物は、一般に低刺激性であるものの、その使用において必要とされる適度な粘度の付与が困難であった。そのため、これまでに難増粘性のアニオン界面活性剤の粘度構築を目的とした様々な技術が提案されている。 Liquid cleaning composition composed mainly of N-acylmethyltaurine salt or amino acid-based surfactant is generally hypoallergenic, but it is difficult to impart an appropriate viscosity required for its use. .. Therefore, various techniques have been proposed for the purpose of constructing the viscosity of an anionic surfactant having a low viscosity.
N−アシルアミノ酸系界面活性剤に脂肪酸ジエタノールアミド及び水溶性無機塩を配合した弱酸性の液体洗浄剤処方が開示されている(特許文献1参照)。同技術によると、N−アシルアミノ酸系界面活性剤の使用感を損なうこと無く、洗浄剤組成物の粘度を上昇させる事が可能であるが、特に十分な粘度構築を行うため無機塩濃度が上限に近い部分の洗浄剤組成物の低温安定性は十分なものではなかった。 A weakly acidic liquid cleaning agent formulation in which a fatty acid diethanolamide and a water-soluble inorganic salt are mixed with an N-acylamino acid-based surfactant is disclosed (see Patent Document 1). According to this technology, it is possible to increase the viscosity of the cleaning agent composition without impairing the usability of the N-acylamino acid-based surfactant, but the inorganic salt concentration is the upper limit in order to build a particularly sufficient viscosity. The low temperature stability of the cleaning agent composition in the portion close to was not sufficient.
水溶性無機塩の配合量を減らして粘度構築を行う目的で、無機塩と両性界面活性剤、半極性界面活性剤およびカチオン性界面活性剤とを併用する液体洗浄剤処方が開示されている(特許文献2参照)。低温安定性の改善等が見られるが、やはり無機塩は必須成分なのでコンディショニング剤の併用が困難になる等の点があるため満足できるものではなかった。 A liquid cleaning agent formulation in which an inorganic salt is used in combination with an amphoteric surfactant, a semi-polar surfactant and a cationic surfactant is disclosed for the purpose of reducing the blending amount of the water-soluble inorganic salt to build the viscosity ( See Patent Document 2). Although improvement in low temperature stability was observed, it was not satisfactory because the inorganic salt was an essential component and it became difficult to use a conditioning agent in combination.
一方、脂肪酸アミドアミンが身体洗浄剤や台所洗剤等の洗浄剤において高い増粘性を有し、更に優れたハンドリング性、溶解性や起泡力を有すると示されている(特許文献3参照)。また、テトラステアリン酸ポリオキシエチレンペンタエリトリットは、難増粘性アニオン界面活性剤を主基剤とする液体洗浄剤に対しても高い増粘効果を有している(特許文献4参照)。 On the other hand, fatty acid amidoamine has been shown to have high viscosity in cleaning agents such as body detergents and kitchen detergents, and further to have excellent handleability, solubility and foaming power (see Patent Document 3). Further, polyoxyethylene pentaerythrit tetrastearate also has a high thickening effect on a liquid cleaning agent containing a poorly viscous anionic surfactant as a main base (see Patent Document 4).
しかし、特許文献3の実施例記載の処方は脂肪族アミドアミンとラウレス硫酸ナトリウムと両性界面活性剤を併用した系であり、難増粘性アニオン界面活性剤(特にアミノ酸系界面活性剤)での効果は確認されていない。
特許文献4のテトラステアリン酸ポリオキシエチレンペンタエリトリットを単独で使用した場合、粘度の上昇が著しく、液体洗浄剤としての適度な粘度に制御することが難しい。
However, the formulation described in the examples of Patent Document 3 is a system in which an aliphatic amidoamine, sodium laureth sulfate and an amphoteric surfactant are used in combination, and the effect of a poorly viscous anionic surfactant (particularly an amino acid surfactant) is Not confirmed.
When polyoxyethylene pentaerythrit tetrastearate of Patent Document 4 is used alone, the viscosity increases remarkably, and it is difficult to control the viscosity to an appropriate level as a liquid cleaning agent.
本発明は、N−アシルメチルタウリン塩等の難増粘性アニオン界面活性剤を主基剤として含有する液体洗浄剤に適度な粘度を付与することができる増粘剤を提供することを目的とするものである。 An object of the present invention is to provide a thickener capable of imparting an appropriate viscosity to a liquid cleaning agent containing a poorly thickening anionic surfactant such as N-acylmethyltaurine salt as a main base. It is a thing.
本発明者らは、難増粘性のアニオン界面活性剤を主基剤として含有する液体洗浄剤への粘度付与の問題を解決する増粘剤を検討した結果、ポリオキシエチレンペンタエリトリットの脂肪酸エステル、脂肪酸アルカノールアミド及び高級脂肪酸を所定の割合で組み合わせることにより、上記課題が解決できることを見出し、本発明を完成するに到った。 As a result of investigating a thickener that solves the problem of imparting viscosity to a liquid cleaning agent containing a poorly thickening anionic surfactant as a main base, the present inventors have investigated a fatty acid ester of polyoxyethylene pentaerythrit. , Fatty acid alkanolamide and higher fatty acid are combined in a predetermined ratio to solve the above-mentioned problems, and the present invention has been completed.

前記一般式(1)中のAOは炭素原子数2〜4のオキシアルキレン基であり、具体的にはオキシエチレン基、1,2−または1,3−オキシプロピレン基、1,2−、1,3−または1,4−オキシブチレン基が挙げられる。これらの中でも、好ましいのはオキシエチレン基と1,2−オキシプロピレン基であり、特に好ましいのはオキシエチレン基である。p、q、r及びsはアルキレンオキサイドの付加モル数であり、p+q+r+sが20〜300となる0又は正の整数であるが、感触やハンドリング性の観点からp+q+r+sが80〜200であれば好ましく、120〜180であればより好ましい。AOは同一でも異なっていてもよく、異なる場合はランダム付加、ブロック付加または交互付加のいずれの付加形式でもよい。 The AO in the general formula (1) is an oxyalkylene group having 2 to 4 carbon atoms, and specifically, an oxyethylene group, 1,2- or 1,3-oxypropylene group, 1,2-1,1. , 3- or 1,4-oxybutylene group. Among these, an oxyethylene group and a 1,2-oxypropylene group are preferable, and an oxyethylene group is particularly preferable. p, q, r and s are the number of moles of alkylene oxide added, and p + q + r + s is 0 to a positive integer of 20 to 300, but p + q + r + s is preferably 80 to 200 from the viewpoint of feel and handleability. More preferably, it is 120 to 180. The AOs may be the same or different, and if they are different, they may be in the form of random addition, block addition, or alternating addition.

ポリオキシアルキレンペンタエリトリットの脂肪酸エステル(A)は、難増粘性のアニオン界面活性剤を主成分とする洗浄剤組成物の全量に対し2〜5質量%程度含有させることにより液体洗浄剤を増粘させることができる。しかし、それ単独では粘度の上昇が急激であるため、実用的な粘度に制御することが難しい。すなわち、一定量配合しないと増粘効果がほとんどないが、適量を超えると急激に増粘し、ゲル化する場合があるなど、安定的に増粘効果を発現させることは極めて困難である。 The fatty acid ester (A) of polyoxyalkylene pentaerythrit increases the amount of liquid cleaning agent by containing about 2 to 5% by mass with respect to the total amount of the cleaning agent composition containing a hardly thickening anionic surfactant as a main component.

評価方法の説明
<粘度試験>
洗浄剤組成物の粘度を25℃において、B型粘度計(ビスメトロン粘度計VS−A1。芝浦システム(株)製)を用い、No.1〜4のローターにて回転数を12rpmに固定して測定した。pHはクエン酸で5.0に調整した。
Explanation of evaluation method <Viscosity test>
At 25 ° C., the viscosity of the cleaning agent composition was adjusted to No. 1 using a B-type viscometer (Bismetron viscometer VS-A1 manufactured by Shibaura System Co., Ltd.). The rotation speed was fixed at 12 rpm with rotors 1 to 4 for measurement. The pH was adjusted to 5.0 with citric acid.
各処方は界面活性剤総量(洗浄剤基剤と増粘剤成分の合計量)が洗浄剤組成物(シャンプー処方)の総質量に対して10.0〜15.0質量%に調整されている。実施例群と比較例群を比較すると、実施例群の増粘剤は、難増粘性アニオン界面活性剤であるココイルメチルタウリンNa、コカミドプロピルベタインの処方に対して、液体洗浄剤として実用的な粘度(300〜6000mPa・s)を付与する効果を示すことが分かる。なお実施例群において、増粘剤成分は速やかに均一に混合・溶解して洗浄剤組成物を調製でき、また得られた洗浄剤組成物は泡立ちがよいものとなった。すなわち実施例群の洗浄剤組成物は、起泡性や溶解性について、洗浄剤としての基本性能を有している。これに対し、増粘剤成分として(A)成分であるPETSのみを配合した比較例2〜5では、その配合量が1.5質量%以下では増粘効果がほとんどないが、2.0質量%を超えると急激に増粘する。また増粘剤成分として成分(A)〜(C)のうちのいずれか1つでも成分を欠く比較例6〜10、12〜16では、増粘効果が全くないか、十分な粘度を付与できない。さらに、増粘剤成分である成分(A)〜(C)をすべて含む場合であっても、規定の配合割合を満たさない場合、例えば(C)成分が所定量を超えた比較例11の場合、増粘性が高くなりすぎる結果となり、実用的な粘度を得ることができなかった。
In each formulation, the total amount of surfactant (total amount of cleaning agent base and thickener component) is adjusted to 10.0 to 15.0% by mass with respect to the total mass of the cleaning agent composition (shampoo formulation). .. Comparing the Example group and the Comparative Example group, the thickener of the Example group is practical as a liquid cleaning agent for the formulation of cocoyl methyl taurine Na and cocamidopropyl betaine, which are poorly viscous anionic surfactants. It can be seen that the effect of imparting a high viscosity (300 to 6000 mPa · s) is exhibited. In the example group, the thickener components could be quickly and uniformly mixed and dissolved to prepare a cleaning agent composition, and the obtained cleaning agent composition had good foaming. That is, the cleaning agent composition of the example group has basic performance as a cleaning agent in terms of foaming property and solubility. On the other hand, in Comparative Examples 2 to 5 in which only PETS, which is the component (A), was blended as the thickener component, there was almost no thickening effect when the blending amount was 1.5% by mass or less, but 2.0 mass. When it exceeds%, the viscosity increases rapidly. Further, in Comparative Examples 6 to 10 and 12 to 16 in which any one of the components (A) to (C) is lacking as a thickener component, there is no thickening effect or sufficient viscosity cannot be imparted. .. Further, even when all the components (A) to (C) which are thickener components are contained, when the specified blending ratio is not satisfied, for example, in the case of Comparative Example 11 in which the component (C) exceeds a predetermined amount. As a result, the thickening became too high, and a practical viscosity could not be obtained.
