发明名称 STABILIZED LIQUID ENZYMATIC COMPOSITIONS
摘要 A stabilizing formulation capable of enhancing the storage and shelf life of liquid enzymatic compositions as well as acting as a dispersant aid for industrial process waters. Such stabilizing formulation contains at least one water-soluble coupling agent selected from a short chain alcohol and a short chain glycol, at least one of (i) a polyethoxylated alkyl diamine and (ii) an amine oxide, and water. The polyethoxylated alkyl diamine and/or amine oxide is present in an amount effective to stabilize one or mote enzymes contained in a liquid enzymatic composition. A stabilized liquid enzymatic composition may contain one or more components of the stabilizing formulation and an enzyme. Methods for the stabilization of a liquid enzymatic composition which involve the step of adding one or more enzymes to a stabilizing formulation, or the step of combining a stabilizing formulatio n with a liquid enzymatic composition containing one or more enzymes where the diamine and/or amine oxide is present, after addition, in an amount effective to stabilize one or more of the enzymes.
