A composition of liquid toothpaste is provided to improve shape, liquidity and dispersion stability of liquid toothpaste having low viscosity using bamboo salt. A composition of liquid toothpaste comprises 0.1-10 weight% of bamboo salt as an active ingredient. The viscosity of the toothpaste composition is 10,000-50,000cP. The toothpaste composition comprises 5-50 weight% of abrasive. The abrasive is selected from precipitated silica, silica gel, calcium monohydrogen phosphate, anhydrous phosphoric acid monohydrogen calcium, hydrated alumina, light calcium carbonate, heavy calcium carbonate, calcium Pyrophosphates, insoluble meta-phosphate, aluminum silicate and zirconium silicate.본 발명은 액상 치약 조성물에 관한 것으로, 죽염을 유효성분으로서 조성물 전체 중량에 대하여 0.1 내지 10 중량%의 양으로 함유하는 것을 특징으로 하는 점도 10,000 내지 50,000 cP의 액상 치약 조성물은, 저점도 액상 치약의 보형성, 유동성 및 분산안정성이 월등히 개선되고 치은염증 억제 효과가 우수하다.
