The influences of six representative surfactants on hair and the scalp were investigated under various conditions such as : irritation, protein denaturation, sorption onto commercial hide powder or keratin powder, change in turnover time of the stratum corneum, dandruff and disintegration of the cuticle.1. Influence of surfactants on scalp.Although the cumulative irritation test, 48-hour closed patch test, and immersion test were performed to assess the irritating effects of surfactants, the results did not agree with each other. The immersion test, which makes essentially the same use of surfactants, gave results in close agreement with those for sorption of sufactants or protein denaturation by surfactants.Amounts of surfactants sorbed by hide powder.Irritation score of immersion test : r=0.671.Amounts of surfactants sorbed by keratin powder.Irritation score of immersion test : r=0.930.Per cent denaturation of OVA by surfactants.Irritation score of immersion test : r=0.880.Turnover times of the stratum corneum due to the surfactants were found to follow the order, AMT≤AGS≤L-Soap≤AP<LS≤ES.Examination of the amounts of dandruff as observed when using AMT shampoo and ES shampoo, each with a different effect on the turnover time of the stratum corneum, showed the amounts to differ remarkably according to the surfactant used.2. Influence of surfactants on hair.The extent of disintegration of cuticle by a surfactant supersonic treatment was found to have the following order : AMT≤AGS≤AP≤ES<LS<L-Soap.Based on the above results, AMT can be a good surfactant as a detergent for the hair and scalp.

ちなみに、↓がmimiさん@mimitan090909にオススメした文献です。 僕ももう一度読み直します
@tenshoku7cosme @EviKazuki よく見たらかずきさんが載せていた文献に吸着量の比較もありました! https://t.co/jvtuFrAail これだとやはりアミノ酸系が有意に残留しやすいとは言えなさそうです。。 (むしろ吸着しにくいというデータになっています;) ちなみに試験法はこちらに↓詳しく載っています https://t.co/FpZLhQ6A1q https://t.co/q0g4KK0GwL
@mimitan090909 たんぱく変性ってことなので、角層バリア機能を破壊することで、皮膚刺激につながるのかなと思ってます。ズバリの文献があるようなのですが、出てこない^^; ↓は結構参考になると思います。 https://t.co/767PhaDuXG
@mimitan090909 @kazunosuke13 同じ著者の別の論文なんですが、 細かく試験条件を確認したら、モルちゃん1時間浸かってたのでかなり過激な試験でした(笑) https://t.co/X561pfACRe 出しゃばってしまいました。 かずのすけさんも補足があれば是非! https://t.co/lNIt1Cjm32
