  • Patent number: 9506001
    Abstract: The invention provides an emulsification technique which permits the formation of functional oil/water or functional granules/water emulsion systems excellent in thermal stability and long-term stability and which can attain the emulsification independent of required HLB of the functional oils, and the dispersion independent of surface properties of the functional granules. In the technique is used an emulsifying dispersant comprising, as the main component, vesicles formed from an amphiphilic substance capable of self-assembly or an emulsifying dispersant comprising single particles of a biopolymer as the main component. The particles made from amphiphilic substances capable of self-assembly are used.

  • Patent number: 6340662
    Abstract: The problem addressed by the invention was to provide a foam regulator system containing silicone and/or paraffin and bis-fatty acid amide which would have a low viscosity, which could be handled at low temperatures and which would have a low percentage content of non-foam-regulating ingredients. This problem was largely solved by an aqueous foam regulator emulsion containing 16% by weight to 70% by weight of active foam regulator based on paraffin wax and/or silicone oil, 2% by weight to 15% by weight of nonionic and/or anionic emulsifier and no more than 80% by weight of water. The foam regulator emulsion is preferably used for the production of partiulate foam regulator granules for use in detergents.

  • Patent number: 5993660
    Abstract: A method for controlling vertical migration of contaminants in an aquifer includes introduction of a solubilizing solution having a surfactant and an alcohol or other light co-solvent. The surfactant is selected to solubilize the contaminant. The alcohol or other solvent is selected to provide the microemulsion with a substantially neutral buoyancy with respect to groundwater. The neutral buoyancy of the microemulsion prevents the normal downward movement which is typical of the solubilized dense non-aqueous phase liquid in surfactant-enhanced aquifer remediation. Thus, the risk that any significant amount of the solubilized dense non-aqueous contaminants will migrate vertically can be controlled. The relative tendency for vertical migration may also be reduced by increasing the injection rate or injected fluid viscosity (by adding polymer), or by reducing the well spacing.
