  • Compositions comprising combination of DEFI and modified DEFI and methods of making
    Patent number: 6562874
    Abstract: Composition may be prepared in a single DEFI reactor comprising mixtures of (1) DEFI (directly esterified fatty acyl isethionate) and (2) a compound produced by the reaction of (a) isethionate with a fatty acid replacement (e.g., a multicarboxylic fatty acid, a fatty acid); or (b) fatty acid with an isethionate replacement (e.g., C2-C24 alcohols, C2-C20 organic acids, amines). Such mixtures are milder than DEFI alone while retaining substantially same foaming benefit.
    Type: Grant
    Filed: December 7, 1999
    Date of Patent: May 13, 2003
    Assignee: Unilever Home & Personal Care USA division of Conopco, Inc.
    Inventors: Leonora Ilardi, Lee Ann Gallagher, Michael Massaro
  • Benefit agent compositions comprising mixtures of &agr;-hydroxy esters
    Patent number: 6322799
    Abstract: The present invention relates to skin care or personal wash cleanser compositions comprising mixtures of short and long-chain alpha-hydroxy acid esters in order to obtain long term benefit of shorter esters while masking short term drying effect of short chain esters.
    Type: Grant
    Filed: April 16, 1999
    Date of Patent: November 27, 2001
    Assignee: Unilever Home & Personal Care USA, division of Conopco, Inc.
    Inventors: Leonora Ilardi, Michael Paul Aronson, Ronni Lynn Weinkauf
  • Benefit agent compositions comprising mixtures of alpha-hydroxy esters
    Patent number: 5961992
    Abstract: The present invention relates to skin care or personal wash cleanser compositions comprising mixtures of short and long-chain alpha-hydroxy acid esters in order to obtain long term benefit of shorter esters while masking short term drying effect of short chain esters.
    Type: Grant
    Filed: July 22, 1997
    Date of Patent: October 5, 1999
    Assignee: Lever Brothers Company Inc.
    Inventors: Leonora Ilardi, Michael Paul Aronson, Ronni Weinkauf
  • Process for preparing narrow range alkoxylated isethionates
    Patent number: 5481031
    Abstract: The present invention relates to a process for preparing narrow range alkoxylated isethionates while reducing amounts of undesirable product using water levels and stir rates unappreciated in the art.
    Type: Grant
    Filed: October 19, 1994
    Date of Patent: January 2, 1996
    Assignee: Lever Brothers Company, Division of Conopco, Inc.
    Inventors: Leonora Ilardi, Christine Wenzel
  • Compositions comprising fatty acid esters of alkoxylated isethionic acid & process for making
    Patent number: 5433894
    Abstract: The present invention provides novel fatty acid esters of alkoxylated isethionic acid and compositions comprising these compounds. Using the alkoxylated isethionates, stable, concentrated (greater 10% total active) solutions can be prepared (when isethionate is primary surfactant) which would not have been possible to prepare using nonalkoxylated isethionate.
    Type: Grant
    Filed: February 2, 1994
    Date of Patent: July 18, 1995
    Assignee: Lever Brothers Company, Division of Conopco, Inc.
    Inventors: Michael Massaro, George Grudey, Leonora Ilardi
  • Fatty acid esters of polyalkoxylated isethionic acid
    Patent number: 5393466
    Abstract: The present invention provides novel fatty acid esters of alkoxylated isethionic acid and compositions comprising these compounds.
    Type: Grant
