ABSTRACT:
The invention provides a high water liquid enzyme prewash composition essentially free of hydrotropes, solvents and dispersants other than nonionic surfactants, and combines: a) effective amounts of a hydrolase enzyme stabilized with a soluble alkaline earth salt; b) a more hydrophilic, first nonionic surfactant having an HLB of greater than about 11; c) a more hydrophobic, second nonionic surfactant having an HLB of less than or equal to about 11; d) at least 80% or greater water; wherein the difference in HLB between said first and second nonionic surfactants is at least about 2, and said nonionic surfactants interact with said water to form an opalescent, structured liquid, said structured liquid both suspending said hydrolase and protecting said hydrolase against deactivation with said water. Suitable adjuncts, such as mildewstats/bacteristats, fragrances and dyes can be included.
