An oral care composition comprising zinc phosphate, sodium fluoride, stannous pyrophosphate, and an organic acid buffer system, as well as methods of using the same.

An oral care composition comprising high water oral care compositions comprising an orally acceptable carrier, zinc phosphate, a first stannous ion source (i.e., stannous fluoride), and a second stannous ion source (i.e., stannous chloride). Methods and uses for this composition are also described throughout.

[Problem] To provide a means for forming on a metal material a film for imparting sufficient corrosion resistance without pretreatment such as zinc phosphate-based conversion coatings. [Solution] A metal surface treatment composition which is used in an energization method having multiple stages in the same bath and which contains Bi ions and a resin emulsion in which at least one type of cationic resin is dispersed in water, wherein the zeta potential of the aforementioned resin emulsion in a pH5-pH9 aqueous medium is +40mV to +100mV.

The invention discloses an improved zinc phosphate cement binding material for dental department. The binding material comprises powder and liquid. The powder comprises the following components: 100 parts of zinc oxide, 10 to 15 parts of magnesium oxide, 3 to 5 parts of silicon dioxide, 1 to 2 parts of bismuth oxide, and 3 to 5 parts of sodium carbonate. The liquid comprises the following components: 100 parts of orthophosphoric acid, 4 to 20 parts of aluminum oxide, 4 to 20 parts of zinc oxide, and 40 to 60 parts of water. The powder and the liquid are blended in a ratio of every 2 grams of powder to 1 milliliter of liquid. The prepared oral binding material is paste with certain flowability before solidification, and can penetrate fine structures on the surfaces of teeth and a recoveredbody so as to play a binding role. The binding material has good mechanical property, greatly weakens the acidity, and does not bring obvious stimulating sense to a patient.

The invention relates to a method for preparing zinc phosphate by using low-grade zinc oxide ores, and belongs to the technical field of inorganic chemical industry. The method comprises the following steps of: by using the low-grade zinc oxide ores as raw materials, leaching and purifying the low-grade zinc oxide ores by using ammonia-ammonium salt to obtain an ammonia leaching purified solution, adding a precipitator for reaction to generate a zinc-ammonium compound salt intermediate precipitation, then completely dissolving the intermediate so that the intermediate solution and a trisodium phosphate solution are subjected to liquid-liquid reaction to generate a zinc phosphate solid precipitation, and obtaining a high-purify powdery zinc phosphate dehydrate product after drying the zinc phosphate solid precipitation, wherein the high-purify powdery zinc phosphate dehydrate product has larger than or equal to 45% of PO4<3->, larger than or equal to 45% of Zn<+> and more than 98% of zinc phosphate and can be used as a raw material for a high-grade anticorrosive paint. The method has the advantages that the technology is simple, the raw materials are abundant in source and low in cost, the liquid-liquid reaction mode is adopted, the reaction speed of the raw materials is fast, and the encapsulation phenomenon is avoided. The product is easy to wash and has fine particle size (+45mum is less than or equal to 0.5%); and the yield of the product is more than 92%. The method not only can be used for promoting the development and utilization of the low-grade zinc oxide ores and but also greatly reducing the production cost of the zinc phosphate product.
