Abstract
Abstract An antimicrobial composition consisting essentially of from about 1 ppm to about 1200 ppm of a Type II endoglycosidase and from about 0.5 ppm to about 1200 ppm of an antimicrobial agent is disclosed. The preferred Type II endoglycosidases to be used in the invention are Endo-D, Endo-H, Endo-F and PNGaseF. The preferred antimicrobial agents are bactericides, fungicides and algicides. The composition can be used in the form of personal care or household cleaning products such as liquid soap, hard surface cleaner, laundry detergent, anti-acne medication, deodorant, shampoo, face cream, mouthwash, dentifrice and denture cleaner.
