  • Patent number: 5804166
    Abstract: Disclosed are hair spray compositions containing non-ionic cellulosic ethers in a solvent base containing water and volatile organic solvent wherein the level of volatile organic solvent in the composition is about 80% or less, and wherein the non-ionic cellulose ether is characterized by a solution viscosity of less than about 50 cps at 25.degree. C. for an aqueous solution containing 3 wt. % solids and 55 wt. % ethanol. The preferred non-ionic cellulosic ether is methylhydroxypropyl cellulose.
    Type: Grant
    Filed: May 9, 1997
    Date of Patent: September 8, 1998
    Assignee: Hercules Incorporated
    Inventors: Anita N. Chan, Anthony B. Clayton, Jashawant J. Modi
  • Patent number: 5741482
    Abstract: Disclosed are air treatment gel compositions comprising in an aqueous medium, at least one volatile air treatment agent and a polymeric gelling agent consisting essentially of seaweed gum, guar or guar derivatives and, optionally, non-sulfated water-soluble polymer, wherein the bulk density of the composition is greater than about 0.9.
    Type: Grant
    Filed: November 6, 1996
    Date of Patent: April 21, 1998
    Assignee: Hercules Incorporated
    Inventor: Jashawant J. Modi
  • Patent number: 5480984
    Abstract: Hydroxyethylcellulose (HEC), hydrophobically modified hydroxyethylcellulose (HMHEC), hydroxypropylcellulose (HPC), methylhydroxypropylcellulose (MHPC), carboxymethylhydroxyethylcellulose (CMHEC), guar, starch, xanthan, hydroxypropylguar (HP Guar) or carboxymethylhydroxypropylguar (CMHP Guar) are stepwise or continuously reacted with hydrogen peroxide to produce aqueous compositions with a solids content greater than 5% by weight at a viscosity at 25.degree. C. below 9500 mPa.s. It is preferred to use 30 to 50% hydrogen peroxide to depolymerize the polysaccharide.
    Type: Grant
    Filed: February 11, 1992
    Date of Patent: January 2, 1996
    Assignee: Aqualon Company

  • Patent number: 5102446
    Abstract: A liquid fertilizer composition suitable for no-till farming contains a stabilizing amount of an admixture of calcium chloride and ammonium polyphosphate or similar nitrogen/phosphorous source in addition to a herbicide. As an improvement over clay suspensions, this liquid fertilizer can be used for one pass planting and herbicide application. Higher amounts of potash can be incorporated in the liquid fertilizer along with sulphur and nitrogen nutrients.
    Type: Grant
    Filed: September 10, 1990
    Date of Patent: April 7, 1992
    Assignee: Aqualon Company
    Inventors: Charles L. Burdick, Jashawant J. Modi
  • Patent number: 5006168
    Abstract: Isopropyl alcohol is partially or completely replaced in an acid fountain solution for lithographic printing by a hydroxypropylcellulose or similar polymer with a molecular weight below 100,000 where a 30% by weight solution of the polymer has a viscosity below 4000 cps at 25.degree.. Printing quality is improved and scumming is controlled when a hydrogen peroxide degraded hydroxypropylcellulose or hydrophobically modified hydroxyethylcellulose replaces alcohol in a fountain solution.
