Abstract: Method for preparing an active-containing nonwoven article involving fixing active ingredients on the surface of non-woven webs and cellulosic mats. The active ingredients can be released (deposited) onto a surface by normal triggering mechanisms, which include the action of a liquid or by friction or rubbing. The fixative systems described herein provide the ability to control high load levels while not interfering with wettability of the fabric or paper. Additionally, ingredients incompatible and reactive with each other can be treated onto the same web and kept as separate particles fixed to the surface until released.

Abstract: A steam-stripping process suitable for the removal of impurities from polysaccharides, including soluble starch hydrolysates, is disclosed herein. This process may be used in combination with other purification processes, such as ultrafiltration, ion exchange, treatment with activated carbon, as well as bleaching process. Soluble starch hydrolysates may also be purified by a combination of ultrafiltration or activated carbon treatment and bleaching. In these processes, the polysaccharide or the soluble starch hydrolysate produced is bland in flavor, free of off-odor, optionally, lighter or white in color and suitable for use in systems requiring these characteristics.

Abstract: Rapidly immobilizing paper coating compositions may be prepared by formulating an aqueous coating composition comprising a cationic starch, pigment and sufficient base to obtain a pH above the pK of the starch derivative so that the starch is no longer cationic; coating the paper substrate; and lowering the pH of the coating such that the starch becomes cationic.
