Patent ID: 8367597

Claim:
A formulation used as a first component in a multi-component peracid generation system, said formulation comprising a mixture of: (a) at least one carboxylic acid ester selected from the group consisting of monoacetin, diacetin, triacetin, monopropionin, dipropionin, tripropionin, monobutyrin, dibutyrin, tributyrin, and mixtures thereof; (b) an enzyme powder comprising (i) at least one enzyme structurally classified as a CE-7 enzyme and having perhydrolysis activity and a signature motif comprising: (A) an RGQ motif at amino acid residues 118-120, (B) a GXSQG motif at amino acid residues 179-183, and (C) an HE motif at amino acid residues 298-299 when aligned to reference sequence SEQ ID NO:1 using CLUSTALW, (ii) at least one excipient, and (iii) optionally at least one surfactant; and (c) at least one buffer; wherein said at least one buffer enhances the stability of said at least one enzyme when present in said formulation as compared to the perhydrolase activity of said at least one enzyme when the at least one excipient is not present.
