<P>PROBLEM TO BE SOLVED: To provide a sebum model for appropriately evaluating a reduction effect of sticky feeling of the head section or for evaluating washability for sebum that gives the sticky feeling to the head section by a simple operation; and to provide a method for evaluating the washability of a detergent for the hair capable of appropriately evaluating the washability for the sebum by a simple operation. <P>SOLUTION: This sebum model includes triglyceride and fatty acid, and a ratio of triglyceride to fatty acid (a mass ratio) is 0.57/1 or more. The method for evaluating the washability of the detergent for the hair includes: bringing a test object that is formed by applying the serum model to the hair, artificial hair or a keratin fiber base material, into contact with the detergent for the hair; then measuring the amount of the sebum contained in the sebum model remaining on the test object; and evaluating the washability of the detergent for the hair by the amount of the sebum. <P>COPYRIGHT: (C)2012,JPO&INPIT |
