Abstract: A process for producing anionic, nonionic, amphoteric or cationic derivatized polysaccharide products which demonstrate high clarity in surfactant-based compositions. The polysaccharide polymer is reacted for a sufficient time and at a sufficient temperature in the presence of water, caustic, and at least one surfactant. The polysaccharide polymer may optionally be reacted with an oxidizing agent, hydrolytic or proteolytic enzymes, molecular weight reducing agents and a cationizing agent and nonionic agent. The formed derivatized polysaccharide has a lower clarity in water than in an aqueous surfactant system. The derivatized polysaccharide product can be used in personal care and or household care products.

Abstract: Latent dispersants were made by the hydrogenation of an alkyl ketene dimer, alkenyl ketene dimer, or ketene multimer. Adding the latent dispersant to paper or paperboard increased its resistance to water and water vapor while maintaining recyclability and repulpability. Additionally, provided is a method for increasing the repulpability of a wax coated paper or paperboard. Dispersants made by the hydrolysis of the alkyl ketene dimer, alkenyl ketene dimer, and ketene multimer are also described.
Abstract: Disclosed herein are cellulase compositions useful as papermaking performance additives for improving paper dry strength of a paper product and reducing refining energy in papermaking processes, and improving paper production. These cellulase compositions are formulated using cellulase, papermaking contaminant control polymers, protein stabilizers and cellulase enhancers. These cellulase compositions measure higher in endo-cellulase activity with better stability than conventional cellulase, and have shown differentiating performance in improving paper dry strength properties versus cellulase alone.
Abstract: Scale deposition on a heat transfer surface in a liquid system such as a heat exchanger is estimated by directing of small portion of the liquid flow through a test cell, consisting of a sensor positioned on and projecting through a conduit wall. The sensor consists of a conductive block containing a heater and having a heated wetted test surface that is flush with the inside of the conduit wall and in contact with the flow through the conduit. Within the conductive block are two temperature sensors which are at different distances from the heated wetted test surface and the heater. The periphery of the apparatus is designed to reduce heat flow through the periphery and allow greater heat flow through the heated wetted test surface. By comparing the temperature differential between the two temperature sensors to the differential when no scale is present, the presence of and amount of scale can be determined, based on reduced heat transfer through the heated wetted surface caused by the accumulated scale.
