  • Patent number: 7378380
    Abstract: A dilutable cleaning composition comprises a pH-elevating component and a pH-lowering component, the composition being such that when it is mixed with water the pH-elevating component dissolves or disperses in the water thereby elevating the pH of the water to at least 8.5 and subsequently the pH-lowering component dissolves or disperses in the water, thereby lowering the pH of the water from at least 8.5 to not more than 4. When the water is at the raised pH, the cleaning composition is effective in removing proteinaceous or fatty soiling, and when the composition is at the lowered pH, the composition is effective at removing alkaline waste materials such as limescale. The cleaning composition is particularly suitable for use as a lavatory or hard surface cleaner.

  • Patent number: 6825155
    Abstract: A dental resin material mixed with a composition containing, as a maincomponent, titanium dioxide whose surface has been partly coated with apatite. In the dental resin material, it is preferable that anatase-, rutile-, brookit-type titanium dioxide or a mixture of these components is used as the titanium dioxide. The apatite for partial coating of titanium dioxide is produced by immersing powdery titanium dioxide in a pseudo body fluid and stirring the immersed titanium dioxide approximately at the same temperature as a human body temperature, i.e., 36° C. In this instance, it is important that the apatite is deposited in the form of platy crystals of less than 2 mm in thickness to cover 0.001-10% of the surface of titanium dioxide.

Further, the cleaned inorganic filler is subjected to a silane coupling processing, thereby the inorganic filler being processed.

  • Patent number: 6300295
    Abstract: A denture cleansing composition for dissolution in water to form a cleansing bath with a initial pH of not more than 4.5. The composition contains at least one bleaching agent, at least one tartar removal agent, and at least one carbonate or bicarbonate. A combination of citric acid and malic acid as tartar removal agents results in increased tartar removal compared to citric acid or malic acid alone. The bleaching agent is an alkali metal or alkaline earth persulfate, perborate, percarbonate, or perphosphate. Preferably, the active agents are present as visually discrete particles. The composition is more stable than compositions having bisulfate as a tartar removal agent and avoids the unpleasant taste due to bisulfate. Potassium monopersulfate is an effective bleaching agent. Sodium bicarbonate and carbonate act as pH regulators and as effervescence agents to avoid gradient formation in the bath and to help remove particles from the dentures.
