  • Patent number: 5904917
    Abstract: A skin cleansing, sunprotecting composition comprisinga. an effective sun protecting amount of a sun protecting hydrophobic agent or mixture thereof,b. a polar organic solvent of lower polarity than water,c. an oil, andd. a cleansing effective amount of a surfactant or mixture thereof wherein the oil/polar solvent ratio on a weight basis is about 1:4 to about 1:0.8.
    Type: Grant
    Filed: September 12, 1997
    Date of Patent: May 18, 1999
    Assignee: Colgate-Palmolive Company
    Inventors: Jairajh Mattai, Louis Oldenhove de Guertechin, Thomas G. Polefka
  • Patent number: 5643861
    Abstract: The present invention relates to a bleach or disinfecting aqueous cleaning composition which is useful for the removal of grease or tar without any mechanical action. In particular, the instant compositions are derived from three liquid phases which merge together at the tricritical point to form one continuum forming the aqueous cleaning composition, wherein the three phases incorporate at least a polar solvent, a non-polar solvent or weakly polar solvent and a water soluble or water low molecular weight water dispersible amphiphile and the composition contains a bleach and disinfecting agent.
    Type: Grant
    Filed: November 17, 1995
    Date of Patent: July 1, 1997
    Assignee: Colgate-Palmolive Co.
    Inventors: Louis Oldenhove de Guertechin, Michel Julemont
  • Patent number: 5639450
    Abstract: An oily single phase combination cleansing, conditioning composition comprisinga. an oil of polarity lower than component b. and having skin conditioning properties,b. a nonionic surfactant of HLB of about 3 to about 6, andc. a second nonionic surfactant of HLB of about 7 to about 15,the quantities of a, b and c selected so that there is a single phase of a, b and c with no more than 2 wt. % water and significant quantities of a is deposited on skin once water is added to the composition.
    Type: Grant

    Date of Patent: June 17, 1997
    Assignee: Colgate-Palmolive Company
    Inventor: Louis Oldenhove de Guertechin
  • Patent number: 5374372
    Abstract: The present invention relates to a liquid crystal composition which comprises approximately by weight 7 to 70% a nonionic surface active agent. 0 to 30% of an aliphatic hydrocarbon having about 6 to 16 carbon atoms, and 10 to 90% of an essentially nonaqueous polar solvent having a Hansen hydrogen bonding solubility parameter at 25.degree. C. of at least 12M Pa.sup.1/2.
