Cleansers, cleaning system, bleaching agents and compositions for environmental conservation

Abstract

The present invention provides a cleansing, bleaching, and sterilizing agent and a cleansing method for the oral cavity, dental prosthetics, and so forth, and a method for manufacturing said agent, a dental prosthetic cleansing system, a bleaching agent for discolored teeth and a method for manufacturing said agent, a bleaching system, a composition for environmental purification containing a photoactive compound composed of phosphorus and calcium, and a paint using the same.

What is claimed is:  
     
         1 . A cleansing.bleaching.sterilizing agent comprising titanium dioxide with a photocatalytic function and an acid typified by phosphoric acid and pyrophosphoric acid.  
     
     
         2 . The cleansing.bleaching.sterilizing agent according to  claim 1 , wherein the agent is a cleansing.bleaching.sterilizing agent for the oral cavity and dental prosthetics, a cleanser for semiconductors and other such electronic components, a cleanser for mechanical parts, a sterilizing cleanser for foods, a sterilizing cleanser for food containers, or a sterilizing cleanser for articles made of cloth, fiber, or metal.  
     
     
         3 . The cleansing.bleaching.sterilizing agent according to  claim 1 , wherein the titanium dioxide is added as a sol solution; 
 the titanium dioxide content in the sol solution is from 0.01 to 80%;    the particle size of the titanium dioxide is from 0.1 to 70 nm;    the titanium dioxide produces photocatalytic activity upon optical irradiation of rutile, anatase, or the like; and
