Latest Patents

One of Hsu's latest patents is for a multilayer bicarbonate/peroxide dentifrice. This invention features an extrudable composite multilayer dentifrice composition designed for cleaning teeth. It contains reactive bicarbonate and peroxide ingredients that do not interact during storage or when extruded together from a container onto a toothbrush. However, they react in the oral cavity when mixed during tooth brushing. The composition comprises two separate dentifrice components, one containing a peroxide ingredient and the other containing a colorant reactive with the peroxide ingredient. These components maintain stable discrete layered phases in interfacial contact without interaction prior to extrusion.

Another significant patent by Hsu involves stabilized dentifrice compositions containing reactive ingredients. This dentifrice composition includes peroxide and bicarbonate compounds that are stabilized to prevent decomposition during storage. The stabilization is achieved by incorporating about 1.0 to about 5.0% by weight of polyethylene glycol 2000 into the composition.
