Abstract
The inactivation in a laundry solution of a hydrolase enzyme by surfactant is prevented by the presence in the laundry solution of an amount of a non-charged enzyme activating means selected from oily hydrocarbons, hydrolyzable fatty acid ester substrates for the enzyme, e.g., triglycerides, essentially lipophilic organic compounds which are not substrates for the enzyme and which bear a polar substituent, and non-ionic surfactants which lower the oil to enzyme critical minimum molar ratio required to activate the enzyme.
