  • Hydrophilic modification of water insoluble polysaccharide as surface-active agents
    Patent number: 9815912
    Abstract: A surfactant produced by reacting naturally occurring polysaccharides that are not water soluble with a hydrophilic substituent on a carboxylic portion of the polysaccharide. In a second reaction, the surfactant is further substituted on a hydroxylic portion with a hydrophobic or lipophilic substituent, so as to make the reaction product both water soluble and capable of attracting oily material that is hydrophobic to be removed from a substrate by cleaning in water. Methods of making the surfactant and the follow-on reaction product are described.
    Type: Grant
    Filed: March 15, 2013
    Date of Patent: November 14, 2017
    Assignee: University of Massachusetts
