Abstract
A hydrolytic enzyme is to be stabilized in a liquid surfactant preparation. This is achieved by using a component that stabilizes the hydrolytic enzyme and encompasses a multiply substituted benzenecarboxylic acid that has a carboxyl group on at least two carbon atoms of the benzene residue.
Claims8
A liquid surfactant preparation comprising a hydrolytic enzyme and a component stabilizing the hydrolytic enzyme, wherein the component stabilizing the hydrolytic enzyme comprises a multiply substituted benzenecarboxylic acid that has a carboxyl group on at least two carbon atoms of the benzene residue, and wherein the preparation is free of boron.
A washing or cleaning method, in which a hydrolytic enzyme selected from the group consisting of protease, amylase, cellulase, glycosidase, hemicellulase, mannanase, xylanase, xyloglucanase, xanthanase, pectinase, β-glucosidase, carrageenase, lipase, or mixtures thereof, is stabilized in a washing bath by a component comprising a multiply substituted benzenecarboxylic acid that has a carboxyl group on at least two carbon atoms of the benzene residue, and wherein the preparation is free of boron.
A liquid enzyme preparation comprising a hydrolytic enzyme and a component stabilizing the hydrolytic enzyme, wherein the component stabilizing the hydrolytic enzyme comprises a multiply substituted benzenecarboxylic acid that has a carboxyl group on at least two carbon atoms of the benzene residue, and wherein the preparation is free of boron.
