  • Toilet bar compositions containing glycolipid surfactants and a process for manufacturing such surfactants
    Patent number: 5501812
    Abstract: The present invention relates to toilet bar soap compositions comprising 1 to 45% by wt. of specified alkali metal (alkyl glycosid) uronates and to processes for making them.
    Type: Grant
    Filed: October 12, 1993
    Date of Patent: March 26, 1996
    Assignee: Lever Brothers Company, Division of Conopco, Inc.
    Inventors: Robert Vermeer, Bijan Harichian, John Gormley, Michael Massaro, George Grudev
  • Toilet bar compositions comprising nonionic glycolipid surfactants and polyalkylene glycol structurant
    Patent number: 5433883
    Abstract: The present invention relates to toilet bar compositions comprising aldobionamides and an amount of polyalkylene glycol sufficient to structure the bar. Unexpectedly it has been found that this polyalkylene glycol structures the bar without simultaneously inhibiting lather formation.
    Type: Grant
    Filed: November 4, 1993
    Date of Patent: July 18, 1995
    Assignee: Lever Brothers Company, Division of Conopco, Inc.
    Inventors: Michael Massaro, George Grudev, Gail B. Rattinger
  • Compositions comprising nonionic glycolipid surfactants
    Patent number: 5389279
    Abstract: The present invention relates to personal product compositions which comprise aldobionamide (i.e. amide of an aldobionic acid or aldobionalactone) as a surfactant in the compositions. The aldobionamide compounds are based on compounds comprising two or more saccharide units. It is believed that such compounds pack less closely, are more water soluble than linear saccharides and thereby allow stable compositions to form more readily.
