  • Patent number: 5988444
    Abstract: A dental product is provided packaged in a telescopically arranged multi-cavity dispensing container having at least two cylinders in an upper body thereof. Peroxide and baking soda are placed as active ingredients in separate respective semi-solid streams, each stream being in separate ones of the cylinders. Uniform dispensing of each stream to deliver relatively equivalent ribbon length of each stream by incorporating a synthetic linear anionic polycarboxylate to adjust viscosity. Preferred polycarboxylates are homopolymers of acrylic, methacrylic and maleic acids, most especially a copolymer of vinyl methyl ether and maleic acid or anhydride.

  • Patent number: 5902568
    Abstract: A method for whitening teeth is provided which involves applying to the teeth a mixture of a peroxide and a bicarbonate salt. Advantageously, the peroxide and bicarbonate salt are stored as active ingredients in separate respective compositions of a dispensing container. Preferably the dispensing container is a pump in the form of an upper and lower body telescopically engageable one with another, the upper body including at least two hollow and separate parallel cylinders each containing one of the compositions. These compositions may then be dispensed through relative compression of the pistons within the cylinders.
