Disinfectant compositions include 0.001 to 10% by weight of hydrogen peroxide or a hydrogen peroxide source based on the total weight of the composition; 0.001 to 20% by weight of at least one amphoteric surfactant based on the total weight of the composition; and 0.001 to 15% by weight of at least one alkali metal or alkaline earth metal salt of a cyclic or heterocyclic aromatic compound comprising at least one hydroxyl group, carboxylic group, or combination thereof based on the total weight of the composition. The disinfectant compositions are particularly effective at treating surfaces contaminated with resistant bacteria, such asat a fast killing rate.

Disinfectant compositions with hydrogen peroxide

Disinfectant compositions include 0.001 to 10% by weight of hydrogen peroxide or a hydrogen peroxide source based on the total weight of the composition; 0.001 to 20% by weight of at least one amphoteric surfactant based on the total weight of the composition; and 0.001 to 0.8% by weight of at least one alkali metal or alkaline earth metal salt of a cyclic or heterocyclic aromatic compound comprising at least one hydroxyl group, carboxylic group, or combination thereof based on the total weight of the composition. The disinfectant compositions are particularly effective at treating surfaces contaminated with resistant bacteria, such asat a fast killing rate.

The present invention relates to a liquid cleaning composition comprising a peroxygen bleach, a sulfonated anionic surfactant and an amphoteric/zwitterionic surfactant where the sulfonated anionic surfactant and the amphoteric/zwitterionic surfactants are in a ratio of from 0.1:1 to 13:1. The combination of the sulfonated anionic surfactant and the amphoteric/zwitterionic surfactants provides for high viscosities and improved cleaning performance.

The invention relates to the use of polycyclic aromatic hydrocarbons (PAHs) such as naphthalene and its alkyl, aryl, or heteroatom substituted analogs, that act as catalysts in the presence of an alkali metal (Li, K, Na) for the reduction of electron-deficient and electron-rich triaryl phosphines to their corresponding alkali metal diaryl phosphide salts. The process is also useful for the catalysis of triaryl phosphine chalcogen adducts such as the sulfides, oxides, and selenides, diaryl(halo)phosphines, triaryl phosphine-borane adducts, and tetra-aryl bis(phosphines) that can also be reduced to their corresponding alkali metal diaryl phosphide salts. The invention also relates to small molecule PAHs and polymer tethered PAHs naphthenics.
