Abstract
Hairstyling products have evolved with the changes in fashion and hairstyling trends. Generally, hairstyling products are evaluated by their hair-holding and hair-arranging abilities. However, since these two factors are contradictory, it is difficult to improve these functions concurrently. For giving the dual function to hairstyling products, we have developed polyacrylate crosspolymer-3 as a new hairstyling polymer having an adhesive ability as a unique character. Conventional hairstyling-polymers (for example, acrylic polymers or vinyl polymers) are designed in order to maintain hair-styles. Those polymers are good at holding hairstyle, but suitable for neither hair-arranging nor re-arranging. In order to give a hair-styling polymer good hair-arranging and strong hair-holding abilities, we ventured to take advantage of the “adhesive ability” which is recognized as an uncomfortable sticky property in conventional hairstyling products. By designing the molecular structure to have crosslinks and low glass transition temperature, we succeeded in achieving an adequate adhesive ability. This unique polymer allows us to develop new hairstyling products for post hair waxes.
