  • Cleaning compositions having enhanced enzyme activity
    Patent number: 6060441
    Abstract: A cleaning composition containing: (a) from about 1 to about 60% by weight of a surfactant component consisting essentially of: (i) a fatty alkyl ether sulfate; (ii) a linear alcohol ethoxylate; and (iii) a nonionic sugar surfactant, having a ratio by-weight of (i):(ii):(iii) in a range of about 0.5 to 1.0:1.5 to 2.5:0.5 to 1.5; and (b) from about 0.1 to about 10% by weight of an enzyme component selected from the group consisting of proteases, amylases, lipases, cellulases, peroxidases, and mixtures thereof, all weights being based on the weight of the composition.
