Abstract: The present invention relates to a liquid detergent composition comprising a surfactant, a subtilisin and a protease stabilizer that is 3-chlorobenzoic acid, 4-chlorobenzoic acid, 3-chlorophenylacetic acid, 3,5-dichlorobenzoic acid, 3-(3-chlorophenyl)propionic acid or their corresponding salts. The composition can further comprise a another enzyme that is a lipase, an amylase, a cellulase or mixtures thereof. The stabilizer can be present at a concentration of 0.001 to 20% w/w. The concentration of the subtilisin can be at least 1.5 g/L.

Abstract: Incorporation of a serine protease inhibitor such as RASI, BASI, WASI (bifunctional alpha-amylase/subtilisin inhibitors of rice, barley and wheat) into a liquid detergent which contains a serine proteasecan stabilize the serine protease and/or a second enzyme and can release the enzyme when the detergent composition is diluted.

Abstract: The present invention relates to a liquid composition comprising an enzyme and an enzyme stabilizer of the following formula: or a salt thereof, wherein R1 is selected from the group consisting of C0-C5 alkyl, substituted C1-C5 alkyl, C1-C5 alkenyl and substituted C1-C6 akenyl and R2, R3, R4, R5 and R6 is selected from the group consisting of hydrogen, C1-C6 alkyl, substituted C1 to C6 alkyl, aryl, substituted aryl, hydroxyl, hydroxyl derivative, amine, C1-C6 alkylated amine, amine derivative, halogen, nitro, thiol, thiol derivative, aldehyde, acid, acid salt, ester, sulfonate or phosphonate.

Abstract: Contact lens are cleaned and disinfected by contacting with an enzyme that functions as a cleaning agent by degrading deposits on the lens, and with an enzyme inhibitor that inhibits remaining enzyme activity and a mild disinfecting agent. If rinsing of the lens is not carried out after cleaning and disinfecting, this procedure prevents eye damage by inhibiting remaining enzyme activity and using a mild disinfectant. Preferred enzymes are proteases such as an acidic aspartic protease, a cysteine protease, a serine protease or a metalloprotease, and preferred enzyme inhibitors function both as an inhibitor and as a mild disinfectant such as chloramine-T, chloramine-B, bacitracin or aryl boronic acids. In a preferred method, the enzyme is subtilisin A and the enzyme inhibitor and disinfectant is chloramine-T.

Abstract: The present invention relates to a liquid composition comprising an enzyme and a phenyl boronic acid derivative enzyme stabilizer of the following formula: ##STR1## wherein R is selected from the group consisting of hydrogen, hydroxy, C.sub.1 -C.sub.6 alkyl, substituted C.sub.1 -C.sub.6 alkyl, C.sub.1 -C.sub.6 alkenyl and substituted C.sub.1 -C.sub.6 alkenyl.

Abstract: The invention relates to a liquid composition which comprises an enzyme and a enzyme stabilizing component. The enzyme stabilizing component is a boronic acid derivative.

Abstract: The invention relates to a detergent composition comprising an enzyme and a boronic acid or borinic acid derivative which acts as a stabilizer for the enzyme in detergent compositions. Specific boronic acid inhibiters include benzofuran substituted boronic acids.

Abstract: A liquid detergent composition comprising a surfactant, an enzyme and a naphthalene boronic acid derivative enzyme stabilizer.
