영문 초록

Anion surfactant, sodium lauryl sulfate (SLS) has been used in shampoo for cleaning. Virgin hair which was not chemically treated was collected from the scalp at the back of the head of an 18-year-old woman. The hair damage of the sample hair was measured by putting the sample in the 1% SLS shampoo solution. The measuring areas were chromaticity, tensile strength and activation energy in protein isothermal curve. The brightness L of the sample hair was (22.2±0.51) before being put in the 1% SLS shampoo solution. But after being in the solution, the figure became significantly higher at (23.5±0.54), (p＜0.05). This implies that anion surfactant SLS causes hair damage and influences brightness L. The tensile strength of the sample hair was (137.5±4.36 g) before being in the 1% SLS shampoo solution. But the figure became low, (148.3±3.16 g), after being in the solution (p＜0.05). This indicates that anion surfactant SLS causes modification in keratin protein and lowers tensile strength. Finally, the activation energy of the sample hair in the 1% SLS shampoo solution was (59.2±4.61 kJ/㏖) 21% lower than that of the sample in the aqueous solution (55.5±3.40 kJ/㏖), (p＜0.05). By measuring brightness, tensile strength and activation energy of the sample hair in the 1% shampoo solution to check hair damage, it has been determined that anion surfactant SLS causes damage to virgin hair. Rinsing hair thoroughly after shampooing, not leaving any residue on hair and using hair protection products including rinses and treatments are recommended.
