[0001] The present invention relates to an aerosol device for containing a composition comprising one or more fatty alcohols, including at least 5% by mass of at least one solid fatty alcohol; one or more C2-C6 monoalcohols, at least 20% by mass of compressed gas; and at least one propellant optionally selected from one or more liquid fatty substances other than liquid fatty alcohols, particularly a cosmetic composition, particularly a hair composition.

[0002] The present invention relates to a method for arranging and / or conditioning keratin fibers, particularly human keratin fibers such as hair, comprising at least one step of applying a composition according to the present invention to the fibers.

[0003] The present invention ultimately relates to the use of a composition sprayed from an aerosol device for arranging and / or conditioning keratin fibers, particularly human keratin fibers such as hair, especially to provide softness, a smooth, non-greasy feel and shine, to facilitate detangling hair, to set hair curls, and to control hair frizz and volume. The aerosol format allows for the delivery of a light mist that does not weigh down the hair and is easy to spray onto the hair. [Background technology]

[0004] Many people are dissatisfied with the appearance of their hair, and those with curly hair in particular may wish to maintain their curls while achieving better curl retention, greater regularity, better movement, and less volume and frizz even in wet conditions. Furthermore, some people find it difficult to control, maintain, and / or style their curly hair.

[0005] Also, some people want their hair to be soft and shiny.

[0006] In particular, for people with curly hair, there is a need to provide a composition that can simplify their styling routine.

[0007] In particular, there is a need to provide a hair care product that can maintain hair curls, simultaneously give curls good fixation and regularity, effectively control hair frizz and volume, withstand humidity, and provide lasting results even after several shampoos.

[0008] In fact, the applicant has surprisingly discovered that an aerosol device comprising a composition containing a combination of one or more solubilized fatty alcohols, at least one C2-C4 monoalcohol, and at least one compressed gas can solve the above problem.

In addition, the composition according to the invention gives a hair conditioning effect and, in particular, a pleasant cosmetic feel, in particular a smooth and non-greasy feel, makes it easier to untangle the hair and makes it possible to give shine. This composition does not give a greasy effect or a waxy effect, does not transfer to the hand when passing the hand through the hair and provides good volume control. The use of an aerosol device makes it possible to distribute the composition well on the hair.

[0012] In addition, the composition according to the invention is advantageously clear or transparent and thus has a unique visual effect for this type of hair product in a transparent container.

[0013] Furthermore, the composition according to the invention is easily distributed on the hair, particularly dry hair, in order to obtain conditioning and / or styling care.
