Abstract
The present invention relates to isotropic enzymatic liquid detergent compositions 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 acrylic based copolymers. Isotropic liquids are obtained without the aid of hydrocarbon solvents. The compositions preferably also contain proteolytic enzymes.
