Abstract: A denture adhesive base composition comprising a multi-carboxylic acid or salt, or mixtures thereof, and ethylene oxide polymer. A denture adhesive composition including this base composition is also provided with other optional adhesive components. Also provided is a method for formulating a novel denture adhesive base composition comprising a multi-carboxylic acid or salt, or mixures thereof, and ethylene oxide polymer.

Abstract: A dental product composition for the treatment of sensitive teeth contains an amorphous bioactive particulate material consisting essentially of calcium, silicon and oxygen in an amount sufficient to alleviate tooth sensitivity by causing the formation of calcium containing mineral within the dentinal tubules of sensitive teeth.

Abstract: A denture adhesive base composition consisting essentially of polyvinyl pyrrolidone and ethylene oxide polymer. A denture adhesive composition including this base composition is also provided with other optional adhesive components. Also is provided a method for formulating a novel denture adhesive base composition consisting essentially of polyvinyl pyrrolidone and ethylene oxide polymer.

Abstract: A superabsorbent acrylic polymer is used to impart desensitizing properties to an oral composition for the treatment of hypersensitive teeth. The mouth feel of the composition is improved by incorporating therein a low molecular weight polyacrylic acid and a divalent salt such as zinc sulfate.

Abstract: The present invention comprises a concentrated solid or semi-solid disinfectant or sterilant composition for use in an aqueous disinfecting or sterilizing solution, comprising an oxidant and a protected glutaraldehyde such as a glutaraldehyde bisulfite addition compound (GBS): ##STR1## or a glutaraldehyde dioxime compound (GDO): ##STR2## The present invention further provides a method for disinfecting or sterilizing a surface or apparatus comprising the steps of mixing a concentrated solid or semi-solid glutaraldehyde sterilant composition comprising an oxidizing compound and a protected sterilant with water to form a solution and bringing the solution into contact with the surface or apparatus.

Abstract: Electroless gold plating baths for plating metallized ceramics wherein the bath comprises (a) alkali metal gold cyanide, (b) alkali metal fluoride, and (c) alkali metal hydroxide. The baths may optionally contain a buffering agent and/or ammonium hydroxide and/or an organic chelating agent. The metallized ceramics contain tungsten, molybdenum, electroless nickel, copper and the like. The gold constituent in the alkali metal gold cyanide may be monovalent, trivalent or mixtures thereof. The method of utilizing such electroless or autocatalytic plating baths is also described and claimed.
