Abstract
A denture cleaner is provided which is non-abrasive and is highly effective for quickly and easily removing stains and tartar deposits from dentures embodying plastic or porcelain teeth and other materials used in dentures. The cleaner is effective for cleaning both full and removable partial dentures, as well as for polishing gold or chromium alloy clasps and removable orthodontic and other oral dental appliances, and has high stability under conditions involving both high and low temperatures. It is characterized by the inclusion therein of Hyamine 3500 and Pluronic P65, which are completely compatible with the other ingredients of the denture cleaner.

A method of removing tarter and stain from a denture with a cleaner, in parts by weight, consisting of from 20 to 24% of water, from 3.6 to 4.4% of dibasic sodium phosphate, from 22 to 26.80% of 85% strength phosphoric acid, from 0.9 to 1.1% of glycerin, from 0.45 to 0.55% of stannic oxide, from 0.03 to 0.07% of n-alkyl (50% C.sub.14, 40% C.sub.12, 10% C.sub.16) dimethyl benzyl ammonium chloride, and from 42.3 to 51.7% of condensate of ethylene oxide with hydrophobic base formed by condensing propylene oxide with propylene glycol, and having an average molecular weight of 3400, comprising applying said composition to a dry denture, immersing said denture in warm water for about 15 minutes and rinsing the denture in water.
