ABSTRACT OF THE DISCLOSURE The invention pertains to enzymatic liquid detergent compositions in which the enzymes comprise a mixture of lipolytic enzymes and proteolytic enzymes. The storage stability of lipolytic enzymes in these proteolytic enzymes containing liquid detergent compositions is enhanced therein by the inclusion of a lower aliphatic alcohol such as ethanol and a salt of a lower carboxylic acid such as sodium formate and by providing for a detergent-surfactant system therein which predominantly consists of a nonionic detergent. The lipases are fungal lipases ex Humicola lanuginosa or Thermomyces lanuginosus. The proteolytic enzymes are preferably of the subtilisin type.
