  • Patent number: 6177100
    Abstract: A cosmetic or pharmaceutical composition for the treatment of the hair and scalp contains nonionic lipids capable of forming a lipidic lamellar phase in combination with an aqueous solution containing at least one cationic surface active agent and/or a quaternized protein.
    Type: Grant
    Filed: March 29, 1999
    Date of Patent: January 23, 2001
    Assignee: L'Oreal
    Inventors: Jean-François Grollier, Isabelle Hansenne-Richoux
  • Patent number: 5660853
    Abstract: The invention relates to a process for manufacturing a cosmetics composition for application to hair, which contains at least one lipid, at least one silicone and water, characterized in that at least one ionic amphiphilic lipid capable of forming vesicles with at least one silicone is mixed with water, in that this mixture is subjected to a process for forming vesicles which encapsulate an aqueous phase, and in that a dispersion of the product obtained is carried out in an aqueous dispersion phase. The invention also relates to a composition obtained by the process and to a process for cosmetic treatment of hair by means of the said composition.

  • Patent number: 5610201
    Abstract: Cosmetic or pharmaceutical composition for the treatment of hair and of the scalp, obtained by using an aqueous solution containing at least one cationic surface-active agent and/or a quaternized protein, in combination with ionic lipids capable of forming a lipidic lamellar phase.
    Type: Grant
    Filed: May 31, 1991
    Date of Patent: March 11, 1997

  • Patent number: 5330758
    Abstract: Cosmetic composition containing at least one silicone, a lipid and water, in which the lipid is a nonionic amphiphilic lipid. The composition is prepared with the aid of a known process for producing nonionic vesicles, in which the nonionic amphiphilic lipid and the silicone are mixed before the process for forming the nonionic vesicles. At least one cationic surface-active agent is preferably introduced into the aqueous dispersion phase after formation of the vesicles.
