Colloid systems and wetting agents; subcombinations thereof; processes of inventions 06/06

20060142399 - Process for defoaming a composition: The present invention describes a process for defoaming a composition using a wax, primarily of natural origin, where the wax is added to the composition that is heated to the melting temperature of the wax....

20060135626 - Mechanical inversion process for marking silicone oil-in-water emulsions: High viscosity silicone compositions such as silicone gums, silicone rubbers, silicone elastomers, and silicone resins, are emulsified by mechanical inversion in which silicone water-in-oil (W/O) emulsions are inverted to silicone oil-in-water (O/W) emulsions. Silicone resins with a viscosity of about one billion centistoke (mm2/s), i.e., 1,000,000,000 centistoke (mm2/s) have been...

20060135627 - Structured surfactant compositions: An aqueous structured surfactant composition, contains water, one or more anionic surfactants, and one or more amine oxides, and exhibits shear-thinning viscosity, is capable of suspending water insoluble or partially water soluble components, and uses a low relative amount of structuring agent and/or surfactant....

20060135628 - Environmentally friendly demulsifiers for crude oil emulsions: The present invention provides environmentally friendly demulsifiers for the break down of petroleum oil applications. The demulsification formulations of the present invention are biodegradable and are low in toxicity. The demulsifiers include a poly(tetramethylene glycol) and an alkylene glycol copolymer linked to the poly(tetramethylene glycol) by a difunctional coupling agent....

20060128815 - Method for controlling droplet size of an emulsion when mixing two immiscible fluids: The invention relates to a method for preparing an emulsion by membrane emulsification enabling control of the dispersed phase size and size distribution by interrupting extrusion of the dispersed phase....

20060128816 - Defoamer emulsion compositions for pulp mill applications: An oil-in-water emulsion useful as a defoamer for pulp and paper mill applications is described. The defoamer has an oil blend (of a triglyceride oil or a mixture of triglyceride oils and silicone), a stabilizing agent (to make the oil blend stable in the emulsion), hydrophobic silica particles, surfactants, dispersants,...

20060128817 - Process for producing acidic aqueous alumina sol: A process for producing a stable acidic aqueous alumina sol containing columnar secondary particles having a length of 50 to 400 nm which are formed by face-to-face coagulation of rectangular plate-like primary particles having a length of one side of 10 to 40 nm and a thickness of 2.5 to...

20060116429 - Process for producing modified stannic oxide sol and stannic oxide/zirconium oxide composite sol: To provide a process for producing a stable modified sol to be used for a component of a hard coat agent to be applied to the surface of plastic lenses or for other applications. It is a sol containing modified metal oxide particles which have a particle size of from...
