  • 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: 6319980
    Abstract: An organic silicon compound emulsion for quickly imparting excellent water-repellent properties to the surfaces of porous inorganic base materials such as concrete, mortar, and masonry. The emulsion is prepared by the steps of emulsifying a mixture consisting of (A) an organoalkoxysilane, (B) an organopolysiloxane having in its molecule at least 2 alkoxy groups or hydroxyl groups bonded to a silicon atom, (C) an anionic emulsifying agent, and (D) water, and heat aging the emulsion at a temperature below 100° C. In another embodiment, the method comprises the steps emulsifying a mixture of the components (A) to (D) and adding an acidic or alkaline substance to the emulsion. In a third embodiment, the method comprises the steps of forming a mixture consisting of the components (A) to (D), adding an acidic or alkaline substance thereto, and performing the emulsification thereafter.

  • Patent number: 6261463
    Abstract: An effective and non-toxic oil spill dispersant combines a predominately oil-soluble surfactant (eg., polyethylene glycol mono-oleate) with a predominately water-soluble surfactant (eg., cocoamide) and a co-solvent for coupling a mixture of the predominately oil-soluble surfactant and the oil spill, with the predominately water-soluble surfactant. Water is included in the combination to help advance the interaction between the predominately oil-soluble surfactant and the predominately water-soluble surfactant as well as the co-solvent. The water component also helps reduce the viscosity of the dispersant to allow it to be pumped under pressure.
