2 Claims. (Cl. 252-99) This invention relates to chlorinated trisodium phosphate and particularly to improved chlorinated trisodium phosphate compositions.
Chlorinated trisodium phosphate, a hydrated mixed salt of trisodium phosphate and sodium hypochlorite, which may be represented by the formula Na PO AiNaOCl- 121-1 0 finds wide application as a component in many cleaning compounds where effective destaining, bleaching or free rinsing properties are a requisite. It is particularly useful as a cleaner-sanitizer in breweries, dairies and other installations in which sterile conditions are necessary. While chlorinated trisodium phosphate has enjoyed wide usage as an industrial cleaner, disinfectant, deodorant and bleaching agent, it possesses objectionable inherent characteristics. For example, the commercially available product is exceedingly dusty, has a strong chlorine odor and is deficient in detergency and wetting properties.
It is, therefore, an object of this invention to provide a novel chlorinated trisodium phosphate overcoming the disadvantages of the prior art. Another object of this invention is to provide chlorinated trisodium phosphate compositions having increased wetting and detergent properties. Still another object of this invention is to provide chlorinated trisodium phosphate compositions in which the chlorine odor is ellectively masked. A further object of this invention is to provide free flowing chlorinated trisodium phosphate compositions not subject to dusting.
In accordance with this invention, chlorinated trisodium phosphate is rendered substantially dustless While the chlo rine odor is masked and its detergency power increased by treating it with polyethylene oxide nonionic detergents. It has been found that the objects of this invention are achieved when the chlorinated trisodium phosphate-detergent compositions contain between about /4% and about 4% by weight of a polyethylene oxide nonionic detergent. Such chlorinated trisodium phosphate compositions exhibit no chlorine odor, are substantially stable for at least six months, and are effectively dedusted. The majority of the compositions of this invention have only a pleasant odor reminiscent of the nonionic agent employed. The effectiveness of the detergent is negligible when the amount of the detergent in the composition is substantially less than about A by weight whereas compositions containing more than 4% detergent are unsatisfactory because of loss of free flowing characteristics and impaired stability.
The polyethylene oxide nonionic detergents used in accordance with this invention are polyethylene oxide adducts or condensates of hydrophobes and contain suiiicient ethylene oxide units to render them water-soluble or water dispersible. Detergent compounds particularly well suited are the polyethylene oxide adducts of tridecyl ether, octylphenol, nonylphenol, tall oil, octylphenyl benzyl ether, sorbitol, sorbitan and the lil.
In order to illustrate the present invention, portions of chlorinated trisodium phosphate were thoroughly blended with a number of polyethylene oxide nonionic detergents in a dough type mixer. Samples of each of the various mixtures were stored at room temperature in closed containers and maintained under surveillance for a period of 7 weeks. Two series of compositions were prepared, one series containing 4% by weight and the other series containing /2% by weight detergent. The detergents employed were the polyethylene oxide adducts of tall oil, octylphenol, nonylphenol and tridecyl ether. The percentage of available chlorine retained by each of these compositions after storage at room temperature for 7 weeks is set forth in the following table.
The percentage of available chlorine indicated in the above table was determined by dissolving the chlorinated trisodium phosphate compositions in water, adding potassium iodide thereto and acidifying with glacial acetic acid. The free chlorine in the resultant solution was titrated to a colorless end point with N/10 sodium thiosulfate solution. It will be noted that in each instance that the chlorinated trisodium phosphate retained Well over of the theoretically available chlorine. Also, each of the compositions was relatively tree-flowing and showed definitely reduced dusting tendencies. These compositions had no chlorine odor and possessed only a pleasant bland scent which varied depending upon the detergent employed.
From the above, it is clear that the present invention accomplishes its objects in providing stable chlorinated trisodium phosphate compositions which are substantially dustless, which have improved detergency and wetting properties and in which the objectionable chlorine odor is effectively masked.
What is claimed is:
1. A substantially dry, solid cleaner-sanitizer composition devoid of the odor of chlorine consisting essentially of from about 99.75% to about 96% of a hydrated mixed salt of trisodium phosphate and sodium hypochlorite, and from about 0.25% to about 4% of a water dispersible nonionic detergent which is a polyethylene oxide condensate of a hydrophobe selected from the group consisting of tridecyl alcohol, octylphenol, nonylphenol, tall oil, sorbitol, and sorbitan.
2. The composition of claim 1 in which the polyethylene oxide nonionic detergent is a polyethylene oxide condensate of tridecyl alcohol.
