  • 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.

  • Patent number: 9815949
    Abstract: In the present invention, biodegradable nanocomposites are introduced which include nanoclay particles, titanium dioxide nanoparticles, polyethylene, polypropylene, starch as a biopolymer, maleic anhydride and glycerol. The obtained nanocomposites have very high physical, mechanical and antimicrobial properties. Proper dispersion and distribution of nanoparticles in composite substrate would help in improving the quality of the product to a great extent. The presence of polypropylene next to polyethylene would eliminate the weak points of polyethylene/biopolymer composite as polypropylene helps to modify the physical and engineering properties of nanocomposites in the presence of nanoclay. Titanium dioxide nanoparticles have antimicrobial properties and would result in products which are useful for food and pharmaceutical industries. Another important aspect of this invention is the production of samples in one step by reaction extrusion method.

  • Patent number: 9815958
    Abstract: Polymeric porous particles have a continuous organic solid phase and at least two sets of discrete pores that are isolated from each other within the continuous phase and that have different average sizes. One set of discrete pores has a larger average size than another set of discrete pores by at least 50%. At least one set of discrete pores is free of detectably different marker materials. There porous particles can be prepared using evaporative limited coalescence techniques with especially chosen discrete pore stabilizing hydrocolloids to protect the pores during formation and to provide the different average sizes.

  • Patent number: 9815961
    Abstract: The invention relates to colorant compositions, and aqueous latex paints or other water-borne coatings made from them, which have a mitigated environmental impact. Levels of solvents, additives and impurities comprising volatile non-aqueous constituents, alkylphenol ethoxylates (and derivatives thereof), crystalline silica, and/or formaldehyde are decreased relative to those typical of preceding generations of colorants and tinted aqueous latex paints and other water-borne coatings. On the other hand, paint-performance as indicated by any of Stormer viscosity stabilization, rheological profile flow/leveling and sag resistance, water sensitivity and color transfer resistance is comparable to a paint in which the aforementioned solvents, additives and impurities are still present.
