  • Patent number: 5631217

  • Patent number: 5520839
    Abstract: A detergent composition contains a combination of two different surfactants, one micellar phase and one lamellar phase, at least one of the surfactants being a glycolipid biosurfactant. Preferred micellar phase biosurfactants are rhamnolipids, sophoroselipids and cellobioselipids, advantageously used in combination with non-glycolipid anionic or nonionic surfactants; while preferred lameilar biosurfactants are trehaloselipids, glucoselipids, and rhamnolipids, advantageously used in combination with micellar biosurfactants. The detergent compositions show enhanced oily soil detergency in fabric washing even when the glycolipid biosurfactants used individually are poor detergents.

  • Patent number: 4824599
    Abstract: The inclusion of proteases with an isoelectric point of less than 10.0 in a detergent composition which comprises a certain, immunologically defined, class of lipases causes a significantly reduced effect of proteases on lipases in comparison with other proteases. The overall performance of the lipase-containing detergent compositions is substantially less affected by these proteases with a pI of less than 10.0.
