Abstract (en)
[origin: EP0359087A2] 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 structure R min (Z) @(CH2)- @-O-R, wherein R = C1-11-alkyl, R min = C1-10-alkyl or H, Z = O or a polyalkoxy residue of the formula (CH2CH2O)m or <CHEM> wherein m = 0-10, r = 0 or 1; R and R min 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.
