抄録
A variety of natural polymers such as biologically derived proteins, lipids, and functional polysaccharides are blended as materials for functionality and safety in beauty products. Of these natural polymers, we developed the polysaccharide curdlan (β-1, 3-glucan), which forms an irreversible gel through heating at a certain temperature or higher, as a beauty product material that has a hairstyling function of memorizing a hairstyle when heat from a dryer is applied. We also used a curdlan gel obtained by heating and appropriately molding this curdlan as a substitute for conductive adhesive paste that is generally used to secure electrodes for measuring brain waves to the scalp. On the other hand, in the research and development of beauty products, efforts are also actively underway to develop a technique to objectively evaluate the effectiveness and functionality of beauty products. We also realized a simple, high precision method that uses keratin film fabricated from a protein solution extracted from hair to detect initial hair degradation, which is ordinarily difficult to measure with high precision due to variations such as individual differences and damage history.
