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 |
20100036114 | PROCEDURE FOR THE PREPARATION OF PURIFIED CATIONIC GUAR - Procedure for the preparation of cationic guar having DS comprised between 0.01 and 3, free from boron and suitable for the use in the cosmetic field and in household cleaning products, comprising the following steps: a) 100 parts by weight of guar flour are reacted with 3-chloro-2-hydroxypropyl trimethylammonium chloride and sodium hydroxide in from 5 to 500 parts by weight of a water and alcohol mixture containing from 20 to 50% by weight of water; b) the amount of water and alcohol is regulated in order to obtain a dispersion containing from 65 to 95% by weight of a of water and alcohol mixture containing from 30 to 50% by weight of water and the dispersion is maintained under stirring at temperature comprised between 15 and 40° C. for at least 10 minutes; c) the mixture is filtered under vacuum and dried to obtain the purified cationic guar. | 02-11-2010 |
20100174062 | MODIFIED XANTHAN GUM, MODIFIED GUM ARABIC, AND MODIFIED TAMARIND SEED GUM, AND METHODS FOR CROSSLINKING XANTHAN GUM, GUM ARABIC, AND TAMARIND SEED GUM - An object is to provide a modified xanthan gum, a modified gum arabic, and a modified tamarind seed gum produced by crosslinking a naturally occurring polysaccharide such as xanthan gum, gum arabic, or tamarind seed gum, by irradiating them with radiation, and methods for crosslinking xanthan gum, gum arabic, and tamarind seed gum. | 07-08-2010 |
20110092696 | High performance low residue guar for hydraulic fracturing and other applications - A process and the guar produced thereby, the guar having superior performance in hydraulic fracturing applications. The guar is produced by first washing, soaking, and prehydrating guar gum splits in hot water. Calcium carbide which is then added to the mixture results in the production of acetylene gas, forcing the guar cells to open during shearing. Shearing the guar gum splits produces flakes, which are then ground and sieved. The fine guar particles produced are spherical in shape, with improved hydration viscosity, and better cross-linking performance than guars presently available. An operator can use twenty-percent (20%) less guar to create the same fracturing geometry, resulting in less formation damage. The improved guar can even be used at ultra low loadings. Further, it leaves less residue after break. | 04-21-2011 |
20110166341 | GLYOXAL FREE PURIFIED CATIONIC POLYGALACTOMANNAN - A glyoxal and boron free purified cationic polygalactomannan may be prepared by reacting a polygalactomannan flour, a nonionically derivatized polygalactomannan flour, or a mixture thereof, with a cationising reagent, adjusting the pH to be from about 4 to about 6; cross-linking the cationic with glyoxal, and filtering and water washing the cationic polygalactomannan to produce a glyoxalated purified cationic polygalactomannan containing not more than 70% by weight of water. In some cases it may be desirable to introduce a buffering agent to the glyoxalated purified cationic polygalactomannan to regulate the pH to from 8.0 to about 9.5, when measured at 1% (dry matter) in water. In other cases, it may be desirable to remove water to produce glyoxal free purified cationic polygalactomannan in powder form. Such compounds are particularly useful in personal care products. | 07-07-2011 |
