Abstract
The present invention provides a stable liquid, aqueous enzyme detergent comprising a mixture of nonionic and anionic surfactants, enzymes and a calcium ion source as an enzyme stabilizer, wherein phase instability is prevented by the use of an alkyl ether carboxylate as a phase stabilizer. This material also surprisingly enhances enzyme stability and imparts additional detergency performance to the liquid detergents. Standard adjuncts may be added to the compositions of this invention.
