Abstract:
A method for determining the percent of a solid material dissolved into a liquid medium is disclosed. The method comprises the steps of combining the solid material and the liquid medium; determining the initial solid concentration (i); determining the dynamic solid concentration (d) using a light scattering technique; and calculating the percent dissolved material according to the formula: [(i - d)/i] x 100 . Methods for determining dissolution rate and particle size using turbidity measurements are also disclosed.
Abstract:
This invention is for di-substituted surfactant precursors, surfactants prepared from them, methods of making the di-substituted surfactant precursors and derived surfactants, and to surfactants having the properties of the described surfactants. The di-substituted surfactant precursors and surfactants are derived from admixing water, surfactant, a hydrolysis catalyst, and an initial quantity of a substituted three-membered heterocycle (a substituted l-oxacyclopropane, a substituted 1-thiacyclopropane, or a substituted l-azacyclopropane) and sustaining an emulsion admixture of the di-substituted surfactant precursor, the water, the heterocycle, the surfactant, and the catalyst to yield the di-substituted surfactant precursor. The di-substituted surfactant precursor is further functionalized to achieve desired hydrophilic properties. A new surfactant product is ultimately provided affording a new combination of (in aqueous admixture) critical micelle concentration, viscosity, and clarity properties.

The disclosure is directed to a thermally-stable dielectric fluid. The dielectric fluid includes (a) an oil, (b) a substituted, hindered phenolic antioxidant having at least two substituted cresol groups being covalently bonded to each other through a methylene bridge, and (c) a substituted, diphenyl amine antioxidant having at least two substituted phenyl groups being covalently bonded to each other through an amine bridge.
Abstract:
Drug particles which are essentially crystalline and have a mean particle size below 2 microns, when dispersed in water, are described. When added to an aqueous medium at 25-95% of the equilibrium solubility of the drug substance, the drug particles show complete dissolution, as characterized by a 95% reduction in turbidity, in less than 5 minutes. Using a controlled precipitation process to prepare such drug particles is also described. Such drug particles exhibit an enhanced dissolution rate and better stability as compared to particles prepared according to processes described in the prior art.
Abstract:
The present invention meets one or more of the above needs and is a composition comprising plurality of capsules wherein the capsules comprise: a core of one or more highly polar liquids; one or more polar active materials dissolved in or dispersed in one or more highly polar liquids; a mixture of one or more polymers and one of more highly polar liquids; or a mixture of one or more polymers, one or more highly polar liquids and one or more polar active materials, and a shell comprising, particles in a polymer matrix or particles; wherein the thickness of the shell is sufficient to prevent passage of the highly polar liquid or the active material through the shell or to control the rate passage of the highly polar liquid or the active material through the shell with the proviso that the one or more polymers may be located in the core, in the polymer matrix of the shell or both.
