表１〜表３に、本発明の実施例及び比較例にかかる皮膚洗浄料の処方を示す。洗浄料は定法に従い調製し、ポンプタイプの泡吐出容器に充填し、評価に供した。 Tables 1 to 3 show the formulations of skin cleansers according to Examples and Comparative Examples of the present invention. The cleaning agent was prepared according to a conventional method, filled in a pump-type foam discharge container, and used for evaluation.
表１に示した通り、アシルメチルタウリン塩を用いた比較例は皮膚刺激性が高かったが、本発明のアシルグルタミン酸塩を用いた実施例は、洗浄力と低刺激性を兼ね備えた、量な洗浄料であった。 As shown in Table 1, the comparative example using the acylmethyltaurine salt was highly irritating to the skin, but the example using the acylglutamic acid salt of the present invention was an amount having both detergency and low irritation. It was a cleaning fee.
表２に示した通り、界面活性剤の純分濃度の合計が１４．２質量％の比較例３は皮膚刺激性が認められたが、界面活性剤の純分濃度の合計が３．６〜１２．４８質量％の実施例２〜４は、皮膚刺激性が低いものであった。 As shown in Table 2, in Comparative Example 3 in which the total net concentration of the surfactant was 14.2% by mass, skin irritation was observed, but the total net concentration of the surfactant was 3.6 to 3.6. 12.48% by mass of Examples 2 to 4 had low skin irritation.
表３に示した通り、界面活性剤の純分濃度の合計が０．９２質量％の比較例４は、洗浄力に劣る結果であった。 As shown in Table 3, Comparative Example 4 in which the total pure concentration of the surfactant was 0.92% by mass was inferior in detergency.
