| abstract |
A perhydrolysis system or activated oxidant system for in situ generation of peracid in aqueous solutions is disclosed, including: (a) a protease enzyme; (b) an ester substrate having the structuren n wherein R = C 1-11 -alkyl, R = C 1-10 -alkyl or H, Z = 0 or na polyalkoxy residue of the formula (CH 2 CH 2 0) m orn n wherein m = 0-10, r=0 or 1; R and R optionally having OH-substituents pendant on or terminating the hydrocarbyl chains, and (c) a source of peroxygen capable of reacting with the protease (a) and the ester substrate (b) to result in proteolytic production of of peracid. |
