LIVING BODY SURFACE STATE MODEL SUBSTRATE, ITS MANUFACTURING METHOD, SIMPLIFIED EVALUATION METHOD OF LIVING BODY SURFACE STATE USING SUBSTRATE, DAMAGED HAIR REFORMING EFFECT SCREENING METHOD, CATIONIC AGGREGATE ACQUIRED BY SCREENING METHOD, AND HAIR COSMETIC INCLUDING CATIONIC AGGREGATE

摘要

PROBLEM TO BE SOLVED: To provide a living body surface state model substrate used as a simplified damaged hair model suitable for evaluating the surface state of a living tissue, especially damaged hair such as colored damage hair, its manufacturing method, a simplified evaluation method of the living body surface state using the substrate, a damaged hair reforming effect screening method using the substrate, a cationic aggregate acquired by the screening method, and hair cosmetics including the cationic aggregate.;SOLUTION: This living body surface state model substrate comprises at least the substrate 1 and a coating for covering the substrate. The living body surface state model substrate is constituted so as to have characteristics described as follows: the coating comprises at least one or a plurality of first coating domains 2 and one or a plurality of second coating domains 3; phase separation is performed between the first coating domains and the second coating domains mutually; and the first coating domains are hydrophobic and the second coating domains are hydrophilic.;COPYRIGHT: (C)2006,JPO&NCIPI
