Abstract
A novel dye stablized cleaning solution of trisodium phosphate and a method of cleaning with said solution is provided by the disclosure. The novelty of said solution and method consists of forming the solution with tap water filtered with an activated charcoal and admixing a specific color indicating dye therewith. The color imparted by said dye remains stable and will not fade or settle-out in said solution. The presence of the trisodium phosphate solution is thereby readily detectable.
Claims12
A method of detecting the presence of aqueous cleaning solutions of trisodium phosphate in kitchen ware comprising the steps of forming said solution with tap water having an electrical conductance and filtered with activated charcoal, and admixing a color indicating dye in said solution whereby the color imparted by said dye will not fade or settle-out of solution, said dye selected from the group consisting of:
- a. disulfonate copper phthalocyanine,
- b. Alizarine Sapphire,
- c. tetraethylrhodamine, or
- d. a mixture of approximately equal parts of Alizarine Cyanone Green G and Fast Wool Yellow.
An aqeuous cleaning solution of trisodium phosphate formed with tap water having an electrical conductance and filtered with an activated charcoal, and having a color indicating dye whereby the color imparted by said dye will not fade and will not settle-out of said solution so that the presence of said trisodium phosphate solution is readily detectable, said dye selected from the group consisting of:
- a. disulfonate copper phthalocyanine,
- b. Alizarine Sapphire,
- c. tetraethylrhodamine, or
- d. a mixture of approximately equal parts of Alizarine Cyanone Green G and Fast Wool Yellow.
