Description

Title of the invention: AEROSOL DEVICE DELIVERING A COMPOSITION BASED ON ETHYLENE OXIDE AND PROPYLENE OXIDE POLYCONDENSATE AND FIXING POLYMER

[0001] The present invention relates to an aerosol device comprising a keratin fiber coating composition which can be dispensed without propellant gas, by mechanical spraying.

[0002] The invention also relates to the use of the device and a method for treating keratin fibers implementing the device according to the invention.

[0003] Styling products are usually used to build, structure, and hold a hairstyle. They typically come in the form of lotions, gels, mousses, creams, sprays, etc., and are generally applied to hair, which is then styled before blow-drying or blow-drying.

[0004] However, currently known aerosol styling products do not give complete satisfaction, both in terms of the distribution of the styling product and the styling product itself.

[0005] In particular, the distribution of the styling product by an aerosol device is generally not sufficiently homogeneous or even. Furthermore, the texture of the styling product is not always pleasant, and the fixing power of the keratin fibers in these products is generally insufficient, particularly in terms of the longevity of the hair styling.

[0006] Furthermore, an increasing number of users of hair styling products are specifically looking for aerosol devices that do not use propellant gas. Indeed, most users have a negative image of propellant gases, often associating them with greenhouse gases that are harmful to the environment.

[0007] There is therefore a real need to develop an aerosol device that distributes homogeneously and regularly, without the use of propellant gas, a composition that gives a pleasant feel and provides good styling properties to keratin fibers, in particular good fixing power of keratin fibers and good persistence of the hairstyle over time.

[0008] These objectives are achieved with the present invention, which relates in particular to an aerosol device, devoid of a propellant, comprising: i. a composition comprising: a. one or more polycondensates of ethylene oxide and propylene oxide, preferably of formula (A): H-(O-CH2-CH2)a-(O-CH(CH3)-CH2)b-(O-CH2-CH2)a-OH (A) in which: a and a', whether identical or different, are integers between 2 and 150, and b is an integer between 1 and 100, b. one or more fixing polymer(s), and c. one or more solvents chosen from water, organic solvents, and their mixtures; ii. a container containing said composition; and iii. at least one mechanical spraying system for said composition.

[0009] The aerosol device according to the invention makes it possible to deliver the styling composition in the form of a continuous spray in a homogeneous and regular manner. The particle size of the spray is as small as that obtained with an aerosol composition comprising a propellant, despite a much lower pressure in the device according to the invention.

[0010] It has been observed that the composition delivered by the aerosol device according to the invention gives a particularly pleasant feel, in particular it does not give a "wetting effect" to the keratin fibers.

[0011] Furthermore, it has been observed that the composition delivered by the aerosol device according to the invention provides very good styling properties. In particular, the composition allows for good hold of the hair over time, both in wet and dry conditions, while adding volume to the hair, and without stiffening the style. In the case of curly hair, the composition according to the invention provides good curl definition.

[0012] In particular, the composition delivered by the aerosol device gives the hairstyle a natural appearance and allows for fluid movement. It also provides a particularly soft and pleasant feel to the hair.

[0013] The styling composition is delivered without the aid of a propellant agent, by the aerosol device according to the invention, which includes a mechanical pumping means. This means advantageously makes it possible to increase the pressure inside the container.

[0014] Furthermore, the device according to the invention has the advantage of being able to deliver the styling product in the form of a continuous spray with an average droplet size equivalent to that obtained with a propellant gas aerosol device, while having a reduced pressure inside the container (approximately 2 to 5 bar for the device according to the invention versus approximately 8 to 9 bar in a propellant gas aerosol device). This reduced pressure in the device according to the invention makes it possible, in particular, to reduce wear on the parts subjected to pressure, and therefore to increase the operating time of the device, but also to reduce the risks associated with storing products under pressure (for example, the risk of explosion during high-temperature storage).

[0015] The absence of a propellant also allows for easier refilling of the device with styling product, thus facilitating its reuse. The device according to the invention therefore has a reduced environmental impact compared to a conventional aerosol device with a propellant (which, moreover, generally cannot be refilled with styling product by the user).

[0016] The invention also relates to a method for treating keratin fibers comprising at least one step of spraying said keratin fibers with a composition, preferably cosmetic, by means of an aerosol device without a propellant agent.

[0017] The invention also relates to the use of the device according to the invention for the treatment, preferably the styling, of keratin fibers.
