TOOTHBRUSH BRISTLE HAVING WATER-REPELLENT PROPERTIES, AND TOOTHBRUSH COMPRISING SAME

摘要

The present invention relates to a toothbrush bristle having water-repellent properties and to a toothbrush comprising same. A toothbrush bristle comprising a water-repellent component, and preferably a perfluorocarbon, has water-repellent properties whereby water absorbency is markedly reduced, and thus can suppress the ability of microbes to propagate and consequently can prevent microbial infection within the mouth as not only is there a substantial reduction in the amount of water remaining in the toothbrush bristles but also there is a very fast water evaporation rate after tooth brushing. Also, the present invention provides a water-repellent toothbrush comprising such water-repellent toothbrush bristles.
