  • Publication number: 20240065950
    Abstract: The present invention relates to an aerosol device containing a composition, notably a cosmetic hair composition, comprising at least 5% by weight of one or more fatty alcohols, at least 20% by weight of one or more C2-C6 monoalcohols, a compressed gas and optionally one or more liquid fatty substances. The invention also relates to the use of the composition according to the invention for shaping and/or conditioning keratin fibres, in particular human keratin fibres such as the hair, and notably for defining the hair curls.

  • Publication number: 20230056796
    Abstract: The present invention relates to a composition, which is preferably aqueous, comprising at least one cationic cellulose-based polymer, at least one sulfonic anionic polymer and at least one fixing polymer. The present invention also relates to a cosmetic treatment process, in particular a process for styling keratin fibers, in particular human keratin fibers such as the hair, using this composition. Finally, the present invention relates to the use of this composition for the cosmetic treatment of keratin fibers, in particular human keratin fibers such as the hair, and in particular for hair styling, i.e. shaping and/or fixing the head of hair.

  • Patent number: 11510861
    Abstract: The present invention relates to a process for treating keratin fibres, especially the hair, comprising the following steps: —application to the keratin fibres of a composition comprising one or more cationic acrylic copolymers comprising at least the units obtained from the following monomers: a) monomer derived from acrylic or methacrylic esters or amides and comprising at least one cationic group, and b) alkyl acrylate or methacrylate monomer, and—application of heat to the keratin fibres using a heating tool, the application of heat possibly taking place before, during or after the application of the composition, preferably during or after.

  • Patent number: 11400042
    Abstract: The present invention relates to a process for treating keratin fibres, in particular human keratin fibres such as the hair, comprising: 1) a step of applying to the keratin fibres a composition comprising: a) one or more compounds chosen from urea and/or urea derivatives, b) one or more polyols, c) one or more amino silicones, 2) a step of heat treatment of the keratin fibres, the heat treatment step 2) preferably being after step 1). The present invention also relates to a composition that may be used in the process according to the invention.
