Low foaming cleaner

摘要

Liquid compositions for cleaning, in particular medical instruments and air conditioning surfaces, said composition excluding surfactants and comprising one or more enzymes including a protease and optionally a hydrolase, a solvent system including a water soluble glycol ether solvent, at least one anionic hydrotrope, and wherein the molar ratio of said at least one hydrotrope to said glycol ether in the composition is selected to preserve the activity of said one or more enzymes. The hydrotrope is advantageously an anionic hydrotrope selected from the group consisting of water soluble anionic hydrotropes of the formula (I) and having no alkyl side chain greater than six carbons in length, for example a xylene sulfonate or cumene sulfonate salt.;

主权项

1. A liquid non-foaming composition for cleaning, consisting essentially of:
one or more enzymes including a protease; a non-foaming solvent system including a water soluble glycol ether solvent; and at least one anionic hydrotrope, wherein the molar ratio of the at least one hydrotrope to the glycol ether in the composition is selected to preserve the activity of the one or more enzymes, wherein the non-foaming composition is surfactant free, and wherein the liquid non-foaming composition can be stored as a concentrate for at least 18 months at 25° C.
