Abstract
The present invention relates to enzymatic liquid detergent compositons comprising lipolytic enzymes. The stability of the lipolytic enzymes is significantly improved therein by inclusion of particular nonionic ethylene glycol containing copolymers therein. These polymers comprise ethylene oxide or ethylene glycol, copolymerized with difunctional acids or vinylic based copolymers. The liquids are obtained without the aid of hydrocarbon solvents.
