Some proteins which construct human hair were solubilized in aqueous solutioons of surfactants generally applied for shampoos.
1) The aqueous solution of sodium dodecylpoly (oxyethylene) sulfate solubilized smaller amounts of proteins from the hair than that of other surfactants used in this experiment.
2) The amount of solubilized proteins had the relationship with the degree of damage in hair.
The higher damaged hair gave larger amounts of solubilized proteins.
3) Solubilization of proteins was influenced with pH of the solution. The minimum amount of solubilized proteins was obtained at pH 56 corresponding to the isoelectric point of human hair.
4) The hair of which proteins was extracted with an aqueous solution of the surfactant had poor water holding capacity and gave much splitted hair caused by combing.
These facts have provided valuable imformation on the effect of surfactants on human hair.
