  • Patent number: 9561166
    Abstract: A personal or household care product includes cationic, nonionic or cationic/nonionic derivatized polysaccharide in combination with a phosphate ester surfactant. The derivatized polysaccharide polymer is formed by reacting the polysaccharide ester surfactant 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.

  • Publication number: 20140328533
    Abstract: A product testing apparatus is described as having one or more imager configured to capture one or more images of a sample having a substrate coating applied to a substrate, a processor in communication with the imager, and a non-transitory processor readable medium, in communication with the processor. The non-transitory processor readable medium stores processor executable instructions that when executed cause the processor to receive the one or more images from the one or more imager. The processor then processes the one or more image by filtering lighting variations in the pixels of the one or more images to identify one or more objects of interest in the one or more images of the cured/uncured substrate coating. The processor quantifies one or more property of the one or more objects of interest. The processor executable instructions then cause the processor to generate one or more signal indicative of the quantification of the one or more objects of interest.
