Abstract: The present invention relates to a two-compartment aerosol device, comprising a styling composition in a first compartment and a compressed gas chosen from air, nitrogen and carbon dioxide, and mixtures thereof, in a second compartment. Said styling composition comprises at least one compound (A) chosen from an anionic carboxylic polymer free of urethane units, a linear sulfonic polyester and a cellulose-based compound in an alcoholic or aqueous-alcoholic medium which comprises at least 5% by weight, relative to the weight of said composition, of a C1-C4 monohydric alcohol. This aerosol device may constitute a hair lacquer. The invention also relates to a styling process using the device of the invention.

Abstract: The present invention relates to a two-compartment aerosol device containing a hair treatment composition in a first compartment and a compressed gas chosen from air, nitrogen and carbon dioxide, and mixtures thereof, in a second compartment, where the hair treatment composition contains, in an alcoholic or aqueous-alcoholic cosmetically acceptable medium, at least one hair sheen agent and/or conditioner in a concentration of greater than 0.4% by weight relative to the total weight of the composition.

Abstract: The present invention relates to a pressurized device for hair fiber styling and to its use for hair fiber styling and/or care. The pressurized device, especially an aerosol, comprises a container, the wall of which is made at least partly of a mixture comprising at least one polyethylene naphthalate and at least one polyethylene terephthalate, a cosmetic composition comprising an aqueous phase comprising at least one foaming agent; and an organic phase comprising at least one propellant selected from halogenated or not halogenated hydrocarbons and mixtures thereof, said device being able to withstand high temperatures.

Abstract: The invention relates to aerosol devices comprising a container which contains, in a cosmetically acceptable medium, a multiblock polymer comprising at least one polyurethane and/or polyurea unit, these devices being suitable for obtaining an initial flow rate of aerosol composition of less than or equal to 0.75 gram per second. The invention is also directed towards a process for shaping or maintaining the hairstyle, comprising the use of these devices, as well as their use for the manufacture of a lacquer or an aerosol spray.
