Claims8
A tubed toothpaste composition comprising a vehicle containing about 45-80% by weight of liquid phase, consisting essentially of from about 15% up to about 35% by weight of the toothpaste of sorbitol and at least about 25% by weight of the toothpaste of water and a solid phase including about 3-10% by weight of the toothpaste of gelling agent wherein drying readily occurs and a hard plug forms at the cap end of a toothpaste tube particularly when the tube is permitted to remain open, typically within about 7 hours of being left open, making it very difficult to effectively extract the paste from the tube, the improvement comprising said toothpaste containing in said gelling agent at least about 3% by weight of the toothpaste of polyvinyl pyrrolidone.
