Description

AEROSOL DEVICE DELIVERING A COMPOSITION BASED ON ETHYLENE OXIDE POLYCONDENSATE AND PROPYLENE OXIDE AND FIXING POLYMER

The present invention relates to an aerosol device comprising a composition for styling keratin fibers which can be dispensed without propellant gas, by mechanical spraying.

The invention also relates to the use of the device and a method for treating keratin fibers using the device according to the invention.

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

The styling products in aerosol devices currently known, however, do not give complete satisfaction, both in terms of the distribution of the styling product and in terms of the styling product itself.

In particular, the distribution of the styling product by an aerosol device is generally not homogeneous or regular enough. In addition, the texture of the styling product is not always pleasant and the fixing power of the keratin fibers of these products is generally insufficient, particularly in terms of persistence of hair shaping.

Furthermore, more and more users of styling products are looking for aerosol devices that do not use propellant gas. In fact, most users have a negative image of propellant gases, often compared to greenhouse gases which are harmful to the environment.

There is therefore a real need to develop an aerosol device which distributes in a homogeneous and regular manner, and without the use of propellant gas, a composition giving a pleasant touch and conferring good styling properties on the keratin fibers, in particular good fixing power. keratin fibers and good persistence of the hairstyle over time.

1. une composition comprenant :
   1. un ou plusieurs polycondensat(s) d’oxyde d’éthylène et d’oxyde de propylène, de préférence de formule (A) :
      H-(O-CH₂-CH₂)_a–(O-CH(CH₃)-CH₂)_b–(O-CH₂-CH₂)_a’–OH (A)
      dans laquelle :
      a et a’, identiques ou différents, sont des nombres entiers compris entre 2 et 150, et b est un nombre entier compris entre 1 et 100,
   2. un ou plusieurs polymère(s) fixant(s), et
   3. un ou plusieurs solvants choisis parmi l’eau, les solvants organiques, et leurs mélanges ;
2. un récipient contenant ladite composition ; et
3. au moins un système de pulvérisation mécanique de ladite composition.

These aims are achieved with the present invention which particularly relates to an aerosol device, devoid of propellant, comprising:

1. a composition comprising:
   1. one or more polycondensate(s) of ethylene oxide and propylene oxide, preferably of formula (A):
      H-(O-CH ₂ -CH ₂ ) _a –(O-CH(CH ₃ )-CH ₂ ) _b –(O-CH ₂ -CH ₂ ) _a' –OH (A)
      in which :
      a and a', identical or different, are integers between 2 and 150, and b is an integer between 1 and 100,
   2. one or more fixing polymer(s), and
   3. one or more solvents chosen from water, organic solvents, and mixtures thereof;
2. a container containing said composition; And
3. at least one mechanical spraying system for said composition.

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 those obtained with an aerosol composition comprising a propellant despite a much lower pressure in the device according to the invention.

It was found that the composition delivered by the aerosol device according to the invention confers a particularly pleasant touch, in particular it does not confer a “wetting effect” on the keratin fibers.

In addition, it was found that the composition delivered by the aerosol device according to the invention confers very good styling properties. The composition makes it possible to obtain good hold of the hair over time in both wet and dry conditions, while providing volume to the hair, and without freezing the hairstyle. In the case of curly hair, the composition according to the invention makes it possible to obtain good curl definition.

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

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

Furthermore, the device according to the invention has the advantage of being able to deliver the styling composition in the form of a continuous spray with an average droplet size equivalent to that obtained with an aerosol propellant gas device, while having a reduced pressure inside the container (from approximately 2 to 5 bars for the device according to the invention compared to approximately 8 to 9 bars in an aerosol propellant gas device). This reduced pressure in the device according to the invention makes it possible in particular to reduce the wear of the parts subjected to pressure, and therefore to increase the operating time of the device, but also to reduce the risks linked to the storage of products under pressure ( for example, the risk of explosion during storage at high temperatures).

The absence of propellant also makes it easier to refill the device with styling composition, and therefore facilitates its reuse. The device according to the invention thus has a reduced environmental impact, compared to a conventional aerosol device with a propellant (which can also generally not be refilled with styling composition by the user).

The invention also relates to a process 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 devoid of propellant.

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