ALKALINE LIQUID HARD-SURFACE CLEANING COMPOSITION CONTAINING A QUATERNARY AMMONIUM DISINFECTANT AND SELECTED DICARBOXYLATE SEQUESTRANTS

摘要

Disclosed is an alkaline liquid hard-surface cleaning and disinfecting composition. The composition comprises from about 0.001 % to about 15 % by weight of a C4-C7 dicarboxylate or hydroxydicarboxylate, from about 0.005 % to about 10 % by weight of a quaternary ammonium disinfectant, from about 0.001 % to about 15 % by weight of a detergent surfactant, a pH of from about 8.5 to about 13, from about 15 % to 98 % by weight of water, and from 0 to about 20 % by weight of an organic solvent having a hydrogen bonding parameter of less than about 7.7. The composition can be used to provide streak-free cleaning and disinfecting of hard surfaces. Moreover, in the presence of the selected dicarboxylates, the quaternary ammonium disinfectant retains its disinfectancy properties and does not precipitate out of solution. The composition can be prepared as a dry formulation.
