Description

本発明は、すすぎ時のきしみ感の大幅な低減化、優れた耐硬水性を有する低刺激性の液体洗浄剤組成物に関する。 The present invention relates to a low irritation liquid detergent composition having a significant reduction in squeakiness during rinsing and excellent hard water resistance.

従来、泡立ちが良く、洗い上がりがさっぱりとする皮膚用の洗浄用界面活性剤として、高級脂肪酸塩が広く用いられている。しかしながら、高級脂肪酸塩は洗浄中に水道水中のカルシウムイオン等の2価金属イオンと結合し金属塩(スカム)を生じる性質があり、これが皮膚に付着する。
このため、特に長鎖脂肪酸塩を用いた場合には、すすぎ時のきしみ感や洗いあがりのつっぱり感、また硬水中で用いた場合、起泡力が低下する、更に脂肪酸塩を中心基剤とする液体製剤においては、低温時における脂肪酸の析出が問題であった。
これらの安定性やスカムの発生を抑える目的で耐硬水性のある両性界面活性剤等を脂肪酸塩と同時に配合する技術が開示されている(特許文献1〜3)。
Hitherto, higher fatty acid salts have been widely used as detergents for washing skin with good foaming and a refreshing finish. However, higher fatty acid salts have the property of binding to divalent metal ions such as calcium ions in tap water during washing to produce metal salts (scum), which adhere to the skin.
For this reason, especially when long-chain fatty acid salts are used, the feeling of squeezing at the time of rinsing and the feeling of washing after washing, and when used in hard water, the foaming power is reduced. In such liquid preparations, precipitation of fatty acids at low temperatures has been a problem.
For the purpose of suppressing the occurrence of these stability and scum, a technique of blending an amphoteric surfactant having hard water resistance simultaneously with a fatty acid salt is disclosed (Patent Documents 1 to 3).

しかしながら、安定性やスカム発生抑制に十分な量の両性界面活性剤を配合するとヌルつくような感触の悪化が発生するなどして好ましくない。
一方、脂肪酸塩のアシル鎖長の分布は、製品の安定性、使用感に大きな影響を与えるものである。
通常脂肪酸石鹸を主成分とする皮膚洗浄料においては、皮膚刺激性を低減し、かつ高温での保存安定性を確保するために、脂肪酸鎖長の長い脂肪酸石鹸、特にミリスチン酸石鹸,パルミチン酸石鹸などの高級脂肪酸石鹸を配合している。
However, if an amphoteric surfactant is added in an amount sufficient for stability and suppression of scum generation, it is not preferable because it causes a feeling of nuisance that is nullified.
On the other hand, the distribution of the acyl chain length of the fatty acid salt greatly affects the stability and feel of use of the product.
In the case of skin cleansers mainly composed of fatty acid soaps, fatty acid soaps with long fatty acid chains, especially myristic acid soaps and palmitic acid soaps, in order to reduce skin irritation and ensure storage stability at high temperatures Higher fatty acid soap such as

これらの特定の脂肪酸塩組成物と先に述べた両性界面活性剤等を配合した技術も開示されている(特許文献4〜5)。また、脂肪酸塩に両性界面活性剤に加えてアミノ酸系界面活性剤を配合する技術も開示されている(特許文献6〜7)。
Techniques in which these specific fatty acid salt compositions and the amphoteric surfactants described above are blended are also disclosed (Patent Documents 4 to 5). Moreover, the technique of mix | blending an amino acid type surfactant with fatty acid salt in addition to an amphoteric surfactant is also disclosed (patent documents 6-7).

しかしながら、これら従来の耐硬水性の改善と使用感の改善を同時に改善できておらず、すすぎ時のきしみ感の大幅な低減化、優れた耐硬水性を同時に満たす、アシル鎖長14以上の脂肪酸塩を主剤として含有する液体洗浄剤組成物は得られていない。
即ち、現在に至るまで充分満足できる高級脂肪酸塩を含有する液体洗浄剤は開発されていない。
However, these conventional hard water resistance improvements and usability improvements have not been improved at the same time, a drastic reduction in squeaking feeling during rinsing, and excellent hard water resistance at the same time, fatty acids having an acyl chain length of 14 or more A liquid detergent composition containing a salt as a main ingredient has not been obtained.
That is, until now, no liquid detergent containing a higher fatty acid salt that is sufficiently satisfactory has been developed.

本発明者は、特定比率の脂肪酸塩混合物に対して、特定の両性又は双性界面活性剤と特定のアシルβアラニン塩を配合することにより、これらの問題点が解決いることを見出し本発明を完成した。 The present inventor has found that these problems are solved by blending a specific amphoteric or zwitterionic surfactant and a specific acyl β-alanine salt with a specific ratio fatty acid salt mixture. completed.

本発明の効果に関して以下の実施例によりさらに詳細に説明する。
表1、2記載の配合比率に従ってサンプルを調整した。
調製した液体洗浄剤組成物は下記各種測定法により、性能評価した。
The effects of the present invention will be described in further detail with reference to the following examples.
Samples were prepared according to the blending ratios listed in Tables 1 and 2.
The performance of the prepared liquid detergent composition was evaluated by the following various measuring methods.

(1)つっぱり感緩和効果の評価
男女パネラー計10名に各実施例及び各比較例をブラインドにて手洗い評価させ、すすぎ時のつっぱり感のなさを評価した。つっぱり感が感じられなかった場合を4点、つっぱり感がほとんど感じられた場合を3点、つっぱり感が感じられた場合を2点、つっぱり感が非常に感じられた場合を1点とし、10名の平均点を算出した
(1) Evaluation of the feeling of squeezing A total of 10 men and women panelists evaluated each example and each comparative example by hand washing with blinds, and evaluated the lack of squeezing feeling during rinsing. 4 points if you did not feel a sense of tension, 3 points if you felt almost a sense of tension, 2 points if you felt a sense of tension, and 1 point if you felt a very strong feeling. The average score of the name was calculated

(2)カルシウム石鹸分散能評価
0.3%オレイン酸ナトリウム5mlを共栓付の試験管に採取する。活性剤濃度0.25%に希釈したサンプル溶液を5gと硬水(300ppm)10mlを加えた後、蒸留水で全量を30gにする。栓をして20回逆立ちさせて振り混ぜて、試験管中の溶液を確認する。試験管中の脂肪酸塩の塊が試験管全体に均一に分散するまで0.25%サンプル溶液を加えたときのカルシウム分散能を算出した。LSDPが低いほどカルシウム分散能が良い。
カルシウム石鹸分散能(LSDP、%)=aml×0.0025/0.025×100
aml:沈殿の生じなくなるまでに加えたサンプルの容量(ml)
(2) Calcium soap dispersibility evaluation 5 ml of 0.3% sodium oleate is collected in a test tube with a stopper. After adding 5 g of a sample solution diluted to an activator concentration of 0.25% and 10 ml of hard water (300 ppm), the total amount is made 30 g with distilled water. Cap and invert 20 times and shake to check solution in test tube. The calcium dispersibility when the 0.25% sample solution was added until the fatty acid salt mass in the test tube was uniformly dispersed throughout the test tube was calculated. The lower the LSDP, the better the calcium dispersibility.
Calcium soap dispersibility (LSDP,%) = aml × 0.0025 / 0.025 × 100
aml: the volume of the sample added until no precipitation occurs (ml)

(3)硬水中での泡立ちの評価
硬度300ppm(CaCO)の水で各実施例及び比較例を界面活性剤濃度0.2wt%に希釈し40℃に温めた試料を1Lトールビーカーに200mLいれる。
回転速度1,100rpmで20秒回転させ3回反転させる。その後泡量をトールビーカーの目盛りを読み取った。
(3) Evaluation of foaming in hard water 200 mL of each sample and comparative example diluted to a surfactant concentration of 0.2 wt% with water having a hardness of 300 ppm (CaCO 3 ) and heated to 40 ° C. in a 1 L tall beaker .
Rotate at 1,100 rpm for 20 seconds and reverse 3 times. The amount of foam was then read on the tall beaker scale.

表1の性能評価に関して、本発明液体洗浄剤組成物の範囲内で調製された実施例1〜15は、目的とする「すすぎ時のきしみ感の低減」であることは官能評価のすすぎ時のつっぱり感緩和効果のスコアが比較的高い値でまとまっていることから実証できた。
また、カルシウム石鹸分散能の値が低いスコアでまとまっており、低刺激性に優れることがわかる。また、硬水中での起泡力が高いころから、硬水でも優れた性能を発揮できる処方となっており、本発明の解決課題をすべて満たしていることがわかる。
Regarding the performance evaluation in Table 1, Examples 1 to 15 prepared within the range of the liquid detergent composition of the present invention are intended to be “reduction of squeaky feeling at the time of rinsing”. This was proved by the fact that the scores of the feeling of relaxation were gathered at relatively high values.
Moreover, the value of calcium soap dispersibility is gathered with a low score, and it can be seen that it is excellent in hypoallergenicity. Moreover, since the foaming power in hard water is high, it is a prescription that can exhibit excellent performance even in hard water, and it can be seen that all the problems to be solved by the present invention are satisfied.

一方、比較例1は実施例1に対してN−アシル−N−メチル−β−アラニン塩を配合しなかった場合であるが、この場合すすぎ時のつっぱり感が強く、カルシウム石鹸分散も良くない結果となった。
比較例2は実施例1に対して、ラウリン酸アミドプロピル酢酸ベタインを配合しなかった例であるが、硬水中での起泡力に不満が残る結果となった。
比較例3は、実施例1の処方中の両性界面活性剤にイミダゾリン型両性界面活性剤を配合された例であるが、カルシウム石鹸分散能が悪い結果となった.
比較例4は本発明とは異なるアニオン性界面活性剤を配合した場合であるが、硬水中の起泡力に不満があった。
比較例5〜7は特定の両性又は双性界面活性剤とアニオン性界面活性剤が範囲外になった物であるが、カルシウム石鹸分散能や硬水中での起泡力が悪いなど、性能に不満が残るものであった。
比較例8〜10は中性無機塩が範囲外になった物であるが、起泡力やすすぎ時の感触など洗浄剤としての性能が悪かった。
On the other hand, Comparative Example 1 is a case where N-acyl-N-methyl-β-alanine salt was not added to Example 1, but in this case, the feeling of squeezing during rinsing was strong, and the calcium soap dispersion was not good. As a result.
Although the comparative example 2 is an example which did not mix | blend the lauric acid amidopropyl acetate betaine with respect to Example 1, it resulted in dissatisfaction with the foaming power in hard water.
Comparative Example 3 was an example in which an imidazoline type amphoteric surfactant was blended with the amphoteric surfactant in the formulation of Example 1, but the calcium soap dispersibility was poor.
Although the comparative example 4 is a case where the anionic surfactant different from this invention is mix | blended, there was dissatisfaction in the foaming power in hard water.
Comparative Examples 5 to 7 are products in which specific amphoteric or zwitterionic surfactants and anionic surfactants are out of the range, but the performance such as poor calcium soap dispersibility and foaming power in hard water. Dissatisfaction remained.
Comparative Examples 8 to 10 were those in which the neutral inorganic salt was out of the range, but the performance as a cleaning agent such as foaming power and feel when it was excessive was poor.

以上のように本発明は、きわめて限定された範囲内ではあるが、解決の課題としていた「すすぎ時のきしみ感の大幅な低減化、優れた耐硬水性を同時に満たす、アシル鎖長14以上の脂肪酸塩を主剤として含有する液体洗浄剤組成物」を充分に実現させていることが判明した。 As described above, although the present invention is within a very limited range, the problem to be solved is “a drastic reduction in squeaky feeling at the time of rinsing, simultaneously satisfying excellent hard water resistance, and having an acyl chain length of 14 or more. It was found that a “liquid cleaning composition containing a fatty acid salt as a main ingredient” was sufficiently realized.

更に本発明の範囲内で以下の処方を作成した。いずれもすすぎ時のつっぱり感がなく、カルシウム石鹸分散能が良い上に硬水中でも十分に起泡力を発現できる液体洗浄剤組成物であった。
Further, the following formulations were prepared within the scope of the present invention. All of them were liquid detergent compositions that had no feeling of squeezing during rinsing, had good calcium soap dispersibility, and were able to exhibit sufficient foaming power even in hard water.
