20090098262 | Optionally Modified/Insoluble Vegetable Gums for Removing Natural or Synthetic Organic Impurities from Liquid Media Contaminated Therewith - Unwanted natural and synthetic organic impurities are removed from liquid media contaminated therewith, e.g., liquids and beverages intended for human consumption, or industrial/wastewaters, by introducing into such media a thus effective amount of an optionally modified/insoluble cationic vegetable gum containing one or more cationic or cationizable substituents, maintaining the cationic vegetable gum in such liquid medium until the organic impurities are sorbed thereon, and thence recovering the vegetable gum/sorbed impurities therefrom, whereby purifying the liquid medium. | 04-16-2009 |
20090197829 | Crosslinked polysaccharides and methods of production thereof - A substantially boron-free method for making a cationic guar comprises reacting particles of polysaccharide with a derivatizing agent to produce derivatized polysaccharide particles, washing the derivatized polysaccharide particles, and contacting, prior to or after the washing step, the particles with a glyoxal compound in order to crosslink the derivatized polysaccharide particles. Also disclosed are methods for making crosslinked derivatized polysaccharides, comprising (a) contacting particles of a polysaccharide with a titanium compound in an aqueous medium having an alkaline pH under conditions appropriate to intra-particulately crosslink the particles; (b) reacting, prior to or after the step of contacting the particles of polysaccharide with the titanium compound, the particles of polysaccharide with a derivatizing agent under conditions appropriate to produce derivatized polysaccharide particles; (c) washing the titanium crosslinked and derivatized particles; (d) contacting, concurrently with or after the step of washing the titanium crosslinked and derivatized particles, such particles with an aqueous medium having an acidic pH under conditions appropriate to substantially de-crosslink the particles; and (e) contacting, concurrently with or after step (d), the de-crosslinked particles with a glyoxal compound under conditions appropriate to intra-particulately crosslink the particles. The crosslinked cationic guar of the present invention is especially useful in home and personal care formulations, especially formulations comprising silicone since it improves silicone deposition. | 08-06-2009 |
20090253599 | Crosslinking method and crosslinked polysaccharide made thereby - A method for crosslinking a polysaccharide, includes the step of contacting particles of the polysaccharide with a titanium compound in an aqueous medium under conditions appropriate to intra-particulately crosslink the discrete particles. | 10-08-2009 |
20100029929 | Method of producing cross-linked polysaccharide particles - A substantially boron-free method for making a cationic guar comprising: reacting particles of polysaccharide with a derivatizing agent to produce derivatized polysaccharide particles, washing the particles, and contacting, prior to or after the step of washing, the particles with a crosslinking agent compound. Also disclosed are methods for making crosslinked derivatized polysaccharides that include contacting particles of a polysaccharide with a first crosslinking agent and/or second cross-linking agent in an aqueous medium under conditions appropriate to intra-particulately crosslink the particles. The first and/or second crosslinking agent can include a copper compound, a magnesium compound, a calcium compound, an aluminum compound, p-benzoquinone, glyoxal, a titanium compound, a dicarboxylic acid, a dicarboxylic acid salt, a phosphite compound or a phosphate compound. The crosslinked polysaccharide of the present invention is especially useful in personal care formulations, especially formulations comprising silicone since it improves silicone deposition. | 02-04-2010 |
