시판 Shampoo의 성분과 세척성
A study on the Components and Detergency of Commercial Shampoos
General components and detergency of commercial shampoos have been investigated and the results are summerized in the following. Shampoos were analyzed for surfactants and additives by KS method and surfactants were confirmed by T.L.C. Considerable differences in amounts of non volatiles and surfactants were found. Three of them contain either lanoline or sterols as additives and in the three. propylene glycol was found in their liquid part. It was shown that predominant sufactant was anionic and in all, except one. a little ampholytic surfactant was detected. But, contrary to forecast, in only one a little of non ionic surfactant was detected. Detergency of shampoos was examined using artificially soiled wool muslin. Considerable difference was found, and all shampoos showed higher detergency than a synthetic powder type detergent for textiles. There were no significant correlation between detergency and amount of surfactants or suspending power of detergents.
