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.

Abstract: The present disclosure relates to a cosmetic composition for treating keratin materials, such as the hair, comprising, in a cosmetically acceptable aqueous medium, at least one water-dispersible sulfonic polyester and at least one polyurethane. This composition may be used for shaping and/or holding the hairstyle. The present disclosure also relates to a device comprising the composition as disclosed herein.

Abstract: The invention concerns aerosol devices comprising a container which contains, in a cosmetically acceptable medium, a multiple block polymer including at least a polyurethane and/or polyurea unit and at least a fixing polymer whereof the glass transition temperature is not less than 40° C., said devices being suitable for obtaining an initial aerosol flow rate not less than 0.55 grams per second. The invention also concerns a method for hair styling or hair setting comprising the use of said devices and their use for making an aerosol lacquer or spray.

Abstract: The invention relates to hair compositions packaged in aerosol form and comprising, in a cosmetically acceptable medium, a polycondensate, such as a multiblock polymer, comprising at least one polyurethane and/or polyurea unit, at least one polyol, an organic solvent, and a propellant gas. The invention is also directed towards a process for shaping or maintaining the hairstyle, comprising the use of these compositions, as well as to their use for the manufacture of hair products, in order to maintain or shape the hairstyle.

Abstract: The invention relates to hair compositions comprising, in a cosmetically acceptable medium, a polycondensate comprising at least one polyurethane and/or polyurea unit and a silicone comprising at least one carboxylic function. The invention is also directed towards a process for shaping or maintaining the hairstyle, comprising the use of these compositions, and to their use for the manufacture of hair products, in order to maintain or shape the hairstyle.
