A method for formation of micro-prilled poloxamer particles is disclosed. The particles find special use in pharmaceutical formulations. The process involves use of atomizing nozzles at higher than normal pressure atomizing gas, high atomizing gas temperature, use of high feed temperatures to reduce the viscosity of the poloxamer and optionally sieving after prill formation in prilling towers. The poloxamer particles are spherical and preferably have an average nominal diameter of less than or equal to 106 microns. The process is very cost effective and rapid.

An index filtration method is disclosed for filtering graft polyol dispersions. The method allows for the rapid filtration of large volumes of graft polyol dispersion in an economical manner. The process can be highly automated. The resulting filtered graft polyol dispersion mainly has particles of 25 microns or smaller and is stable under a variety of conditions for at least 9 weeks.

The present invention is a method of producing dry, alkali metal or ammonium carboxylic acid salt particles. In accordance with the invention, a molten carboxylic acid is mixed with a solution of an alkali metal-containing or ammonium-containing alkaline compound and the carboxylic acid and alkaline compound are reacted to form the carboxylic acid salt. Water is then removed from the carboxylic acid salt to produce dry, carboxylic acid salt particles. The feed ratio of the molten carboxylic acid and the alkaline compound is controlled to neutralize the carboxylic acid in the process.

A method for producing a granulated riboflavin product comprises making a specific mixture of riboflavin, binder and water, followed by homogenizing the mixture and thereafter spray-drying the homogenized mixture so that granules are produced. The mixture has a relatively high vitamin and binder content but is reduced to a relatively low viscosity (via homogenization) so that spray drying can be performed.

The subject invention relates to a process for preparing lubricated water-soluble vitamin powders. The water-soluble vitamin powders are lubricated by combining them with a lubricant at a temperature sufficient to melt the lubricant. The powders are directly compressible into tablets and are resistant to demixing.
