  • Patent number: 5439690
    Abstract: A hazard-free method for controlling insects using a non-toxic composition that kills by dehydration. The invention includes a process for making the composition in the form of crystalline particles which penetrate directly through the exoskeleton of an insect. In operation, the particles work themselves between the insect's protective body plates and then pierce the exoskeleton. Once inside, the particles absorb up to four times their weight of the vital body fluids of the insect. The penetration of the body plates and exoskeleton and/or dehydration ultimately results in death of the insect.

  • Patent number: 5204087
    Abstract: A composition for foaming preparation comprising (a) an organic acid of which the crystal surface is coated with a sugar and (b) a carbonate is disclosed. In the composition, an organic acid is completely shut off from a carbonate by a sugar coating so that the acid does not react with the carbonate over a prolonged storage time. When the composition is put into mouth, the sugar which covers the acid is readily dissolved, allowing the acid and the carbonate to react and to generate carbon oxide gas. An excellent foaming calcium preparation can be produced by using calcium carbonate as the carbonate or by adding other salt of calcium to the composition. Such a calcium preparation gives a good taste and favorable feeling upon administration. It is especially suitable for regular administration of calcium over an extended period of time.
