  • Lipophilic hydroxylated acid, its use in cosmetics and pharmacy, and its process of preparation
    Patent number: 6039961
    Abstract: The invention relates to new lipophilic hydroxylated acids wherein said lipophilic hydroxylated acid comprises a hydrophobic hydrocarbon chain having from 7 to 30 carbon atoms grafted onto the hydroxyl functional group and/or the acid functional group of the lipophilic hydroxylated acid via a covalent bond chosen from the group consisting of an ester bond on the hydroxyl functional group, an anhydride bond on the acid functional group and an amide bond on the acid functional group, provided that, in the case of an amide bond, this hydrophobic hydrocarbon chain consists of an alkyl radical having from 10 to 30 carbon atoms resulting from a monoamine, or a combination of these bonds. These new derivatives are useful as active ingredient of cosmetic or pharmaceutical compositions and as emulsifying agents.
    Type: Grant
    Filed: April 27, 1998
    Date of Patent: March 21, 2000
    Assignee: Coletica

  • Polyose/fatty acid complex product with a high fatty acid content, use as an emulsifier or moisturizer and emulsifying or moisturizing composition in which it is present
    Patent number: 5422111
    Abstract: The invention relates to a polyose/fatty acid complex product. This complex product is the reaction product of at least one polyose with at least one fatty acid, in particular in the form of a halide or the anhydride. The fatty acid can be saturated or unsaturated and can comprise from 8 to 28 carbon atoms. This complex product has a high moisturizing capacity and, surprisingly, an emulsifying capacity and can be used to prepare valuable cosmetic or pharmaceutical compositions.
