Title: Dentifrice
Inventor: KAWAHATA AKIO
IPC: A61K8/9761
Filed: 2019-04-29
Abstract: To provide a dentifrice that comprises naturally derived extracts, has a high antibacterial effect, and is also stable for long-term storage, from a perspective of Chinese herbal medicine.SOLUTION: A dentifrice comprises hinokitiol and persimmon tannin as components, and at least one of hinokitiol and persimmon tannin is selected from naturally occurring extracts including hinokitiol and persimmon tannin.EFFECT: A combination of hinokitiol and persimmon tannin exerts high antibacterial activity and is stable for long-term storage due to its synergistic effect. Furthermore, since hinokitiol and persimmon tannin are extracted from naturally occurring materials, they comprise not only hinokitiol and persimmon tannin but also various components contained in naturally occurring materials. Therefore, the dentifrice effectively exhibits antibacterial action, anti-inflammatory action, and astringent action by a further synergistic action with various components contained in the naturally derived materials, and also exhibits a stable storage performance in an extended period of time.SELECTED DRAWING: Figure 7
