Latest Patents
DeLeeuw holds a patent for a "High water liquid enzyme prewash composition." This invention provides a high water liquid enzyme prewash composition that is essentially free of hydrotropes, solvents, dispersants, and surfactants, other than nonionic surfactants. The composition combines a hydrolase enzyme stabilized with a first enzyme stabilizer, which is a soluble alkaline earth salt. It also includes a more hydrophilic first nonionic surfactant with an HLB greater than about 11, a more hydrophobic second nonionic surfactant with an HLB less than or equal to about 11, and at least about 80-99% water. The structured liquid formed by the nonionic surfactants interacts with water to suspend the hydrolase and protect it against deactivation.
