Zusammenfassung: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 an enzyme stabilizer, wherein the enzyme stabilizer is a boron compound, a reducing agent, a short chain inorganic or organic acid, or a mixture thereof; 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 being selected from the group consisting of alkoxylated alcohols and alkoxylated alkylphenols; the structured liquid both suspending the hydrolase and protecting the hydrolase against deactivation with the water. The inventive high water liquid enzyme prewash compositions may also contain a second hydrolase enzyme and a second enzyme stabilizer. Suitable adjuncts, such as mildewstats/bacteristats, fragrances and dyes can also be included.
