  • Foam stabilization and oily soil removal with associative thickeners
    Patent number: 8759277
    Abstract: The invention involves foam stabilization compositions that rely upon anonionic/hydrophobic interaction. According to the invention, an associative thickener is used to provide long range nonionic/hydrophobic interaction with the hydrophobic groups of the surfactants present in the same. The interaction must be of sufficient character so that the components can maintain long range intermolecular networking, causing longer lasting and increased foam production, even in the presence of hydrophobic/oily soils. The system provides an environmentally friendly alternative for traditional foaming enhancers such as cocamide DEA.

  • Method for the emulsification of ASA with polyamidoamine epihalohydrin (PAE)
    Patent number: 8747616
    Abstract: The invention is directed towards methods and compositions for improving the sizing of paper using PAE. Proper sizing of paper requires that a sizing agent adequately disperse so as to evenly distribute on the paper. Proper sizing also requires that the agent not cause runnability or chemical problems with other materials or equipment used in the papermaking process. PAE displays unexpected attributes that allow it to disperse sizing agents. Best of all it is not subject to the same overdose effect of typical emulsifiers such as cationic starch. As a result PAE is an excellent option for use in sizing paper.
