  • Patent number: 5789364
    Abstract: The invention provides a high water liquid enzyme prewash composition essentially free of hydrotropes, solvents, dispersants and surfactants, other than nonionic surfactants, combining: a hydrolase enzyme stabilized with a first enzyme stabilizer, wherein the first enzyme stabilizer is a soluble alkaline earth salt; a more hydrophilic, first nonionic surfactant having an HLB of greater than about 11; a more hydrophobic, second nonionic surfactant having an HLB of less than or equal to about 11; and at least about 80-99% water; wherein the difference in HLB between the first and the second nonionic surfactants is at least 2; the nonionic surfactants interact with the water to form an opalescent, structured liquid; the first and the second nonionic surfactants are selected from the group consisting of alkoxylated alcohols and alkoxylated alkylphenols; the structured liquid both suspends the hydrolase and protects the hydrolase against deactivation with water.
