Claims16
An enzymatic cleaning composition for use in an aqueous solution consisting of a microbial cutinase and a cleaning effective amount of a non-ionic surfactant or a combination of non-ionic surfactants compatible with said cutinase wherein said composition comprises from about 0.01 percent to about 5.0 percent by weight of cutinase based on the weight of the non-ionic surfactant wherein the weight of the cutinase employed in said composition is sufficient so that upon dilution in said aqueous solution there is sufficient cutinase so as to achieve a cutinase concentration of at least 0.05 mg/liter.
An enzymatic composition for use in an aqueous solution consisting of a microbial cutinase and one or more enzymes selected from the group consisting of lipases, amylases, cellulases, peroxidases and proteases, and a cleaning effective amount of a non-ionic surfactant or a combination of non-ionic surfactants compatible with said cutinase wherein said composition comprises from about 0.01 percent to about 5.0 percent by weight of cutinase based on the weight of the non-ionic surfactant where the weight of the cutinase employed in said composition is sufficient so that upon dilution in said aqueous solution there is sufficient cutinase so as to achieve a cutinase concentration of at least 0.05 mg/liter.
An enzymatic cleaning composition for use in an aqueous solution comprising a microbial cutinase derived from Pseudomonas mendocina, ATCC 53552, a protease and a cleaning effective amount of a non-ionic surfactant or a combination of non-ionic surfactants compatible with said cutinase, wherein said cutinase is present in said composition in an amount from about 0.01 weight percent to about 5 weight percent based on the weight of the surfactant wherein the weight of cutinase employed in said composition is sufficient so that upon dilution in said aqueous solution there is sufficient cutinase so as to achieve a cutinase concentration from about 0.05 mg/liter to about 100 mg/liter and further wherein said protease is present in said composition in an amount from about 0.001 weight percent to about 5 weight percent based on the weight of the surfactant and present in an amount such that upon dilution in said aqueous solution there is sufficient protease so as to achieve a protease concentration from about 0.05 ppm to about 5 ppm.
An improved method for enzymatically cleaning a material having a stain comprising a lipid or polymerized lipid, the method consisting of:
- (a) selecting a cutinase enzyme;
- (b) selecting a non-ionic surfactant or a combination of non-ionic surfactants compatible with said cutinase enzyme;
- (c) forming an aqueous solution with a cleaning effective amount of said non-ionic surfactant or a combination of non-ionic surfactants and said enzyme wherein said concentration of said enzyme in said solution is at lease about 0.05 mg/liter;
- (d) contacting the material with the solution of step (c);
- and
- (e) rinsing the material of step (d).
