Abstract

The present invention relates to an aerosol device comprising: —a container containing: —one or more propellants, and—a composition comprising one or more sebum-absorbing powders with a sebum uptake of greater than or equal to 35 ml/100 g, the propellant(s) possibly being present in the composition or, in the container, separate from the composition, —a means for dispensing the said aerosol composition, comprising a diffuser equipped with at least two, and better three, spray orifices ( 22 ). The invention also relates to a process for the dry-washing and cosmetic treatment of keratin materials, comprising a step of applying to the hair the cosmetic composition, sprayed from the particular aerosol device.

First claim

1 .- 19 . (canceled)

20 . An aerosol device comprising:
(a) a container, said container comprising:
at least one propellant, and
a composition, said composition comprising:
at least one sebum-absorbing powder with a sebum uptake of greater than or equal to 35 ml/100 g;

wherein the at least one propellant is present in the composition and/or in the container, separate from the composition; and
(b) at least one diffuser comprising at least two spray orifices.

21 . The device according to claim 20 , wherein the at least one sebum-absorbing powder is chosen from modified starches.

22 . The device according to claim 20 , wherein the at least one propellant is present in the composition, and the at least one sebum-absorbing powder is present in an amount ranging from about 0.1% to about 90% by weight, relative to the total weight of the composition.

23 . The device according to claim 20 , wherein the composition further comprises at least one styling powder comprising at least one water-insoluble mineral compound, chosen from metal carbonates, oxides, sulfates, and silicates containing magnesium.

24 . The device according to claim 20 , wherein the at least one water-insoluble mineral compound is chosen from calcium carbonate, magnesium carbonate, alumina, barium sulfate, and magnesium oxide.

25 . The device according to claim 23 , wherein the at least one propellant is present in the composition, and the at least one water-insoluble mineral compound is present in an amount ranging from about 0.1% to about 30% by weight, relative to the total weight of the composition.

26 . The device according to claim 20 , wherein the composition further comprises at least one C 2-4 monoalcohol.

27 . The device according to claim 26 , wherein the at least one propellant is present in the composition, and the at least one C 2-4 monoalcohol is present in an amount ranging from about 1% to about 70% by weight, relative to the total weight of the composition.

28 . The device according to claim 20 , wherein the at least one propellant is chosen from air, nitrogen, carbon dioxide, dimethyl ether, C 3-5 alkanes, 1,1-difluoroethane, and mixtures thereof.

29 . The device according to claim 20 , wherein the at least one propellant is present in the composition in an amount ranging from about 10% to about 90% by weight, relative to the total weight of the composition.

30 . The device according to claim 20 , wherein the composition further comprises at least one non-elastomeric silicone.

31 . The device according to claim 30 , wherein the at least one non-elastomeric silicone is chosen from silicone gums having a viscosity greater than 0.5×10 −3 m 2 /s (500 cSt).

32 . The device according to claim 20 , wherein the composition further comprises at least one fatty ester.

33 . The device according to claim 20 , wherein the composition further comprises at least one additive chosen from conditioning or fixing anionic, cationic, nonionic, amphoteric or zwitterionic polymers, fragrances, dyes, protective screening agents, acids, bases, nacres, and glitter flakes.

34 . The device according to claim 20 , wherein the at least one diffuser comprises at least three spray orifices arranged at 120° relative to each other around the spraying direction.

35 . The device according to claim 20 , wherein the at least two spray orifices are fixed on a single nozzle.

36 . The device according to claim 20 , wherein each of the at least two spray orifices is connected to a feed channel that is inclined obliquely relative to the spraying direction.

37 . A process for the dry-washing and cosmetic treatment of keratin materials, comprising:
(I) spraying a cosmetic composition from an aerosol device, comprising:
(a) a container, said container comprising:
at least one propellant, and
a composition, said composition comprising: c
at least one sebum-absorbing powder with a sebum uptake of greater than or equal to 35 ml/100 g;

wherein the at least one propellant is present in the composition and/or in the container, separate from the composition; and
(b) at least one diffuser comprising at least two spray orifices;
(II) applying said composition to wet or dry hair; and (III) optionally, rinsing the hair after an optional leave-on time.
