    Type: Grant
    Filed: February 25, 1997
    Date of Patent: December 29, 1998
    Assignee: Elf Atochem North America, Inc.
    Inventors: John Distaso, Azucena G. De Guzman

    Type: Grant
    Filed: February 25, 1997
    Date of Patent: December 22, 1998
    Assignee: Elf Atochem North America, Inc.
    Inventors: John Distaso, Azucena G. De Guzman
  • Patent number: 5821209
    Abstract: Improvements in the retardation of water evaporation from benzyl alcohol containing water-in-oil emulsions by incorporating in the organic phase thereof an effective amount of a terpene.
    Type: Grant
    Filed: February 25, 1997
    Date of Patent: October 13, 1998
    Assignee: Elf Atochem North America, Inc.
    Inventors: John Distaso, Azucena G. De Guzman
  • Patent number: 5817612
    Abstract: Aqueous paint stripper formulations containing a solvent system comprised of an ester such as benzyl formate and methods for using the same to strip paint.
    Type: Grant
    Filed: December 23, 1996
    Date of Patent: October 6, 1998
    Assignee: Elf Atochem North America, Inc.
    Inventor: John Distaso
  • Patent number: 5780409
    Abstract: Natural or synthetic wax dissolved in the continuous organic phase of an water-in-oil emulsion retards evaporation of water from a dispersed aqueous phase. An in situ prepared equilibrium mixture of benzyl alcohol, formic acid and benzyl formate emulsified with oleic hydroxyethyl imidazoline or similar oil soluble emulsifying agent is thickened with hydroxypropyl cellulose or hydroxypropyl methylcellulose and contains 0.1 to 1.0% by weight paraffin wax with a melting point of 47.degree. to 65.degree. C. Wax dissolved in the organic phase retards evaporation of water, and formic acid or ammonia which are very volatile in comparison with benzyl alcohol forming the major component of the organic phase. A petroleum distillate is used to pre-wet a hydroxypropyl cellulose thickener and dissolve the wax.
    Type: Grant
    Filed: September 3, 1996
    Date of Patent: July 14, 1998
    Assignee: Elf Atochem North America, Inc.
    Inventor: John Distaso
  • Patent number: 5744438
    Abstract: Stripping action of an alkaline paint stripper is improved when ammonia is partially or completely replaced with ammonium bicarbonate or chemical equivalent thereof which decomposes into ammonia and carbon dioxide. A benzyl alcohol solvent system containing at least ammonium bicarbonate is preferably a water-in-oil emulsion emulsified with oleic hydroxyethyl imidazoline and thickened with hydroxypropyl cellulose or hydroxypropyl methylcellulose. A mixture of ammonium carbamate and ammonium bicarbonate identified as ammonium carbonate is the preferred activator for this alkaline paint stripper. Improved stripping can also be provided by reacting ammonium bicarbonate and ammonia in situ within the water-in-oil emulsion.
