Phenolic synthetic detergent-disinfectant

Abstract

Unique and novel phenolic synthetic detergent-disinfectant compositions are provided wherein the detergent component is an anionic detergent and the phenolic components thereof consist essentially of ortho phenylphenol in admixture with high activity and intermediate activity phenolics, the ratio of ortho phenylphenol to the high and intermediate activity phenolics being from about 4:1-1.1:1. When prepared as a use dilution, the ortho phenylphenol is present in an amount of at least about 450 p.p.m. When the ortho phenylphenol is employed only with the high activity phenolics, the preferred minimum amount of ortho phenylphenol should be at least about 600 p.p.m. and the ratio of the ortho phenylphenol to the high activity phenolics can then be from about 2.5:1-1.5:1 and, when used with intermediate activity phenolics at the same preferred minimum level, the ratio of the ortho phenylphenol to the intermediate activity phenolics can be from about 2.1:1-1.25:1. The novel phenolic synthetic detergent-disinfectant compositions of the invention are effective not only against Staphylococcus and Salmonella but also against the troublesome Pseudomonas species in hard water.
