The present invention relates to a composition in the foam form comprising a continuous liquid fatty phase.
The compositions according to the invention can be compositions for making up or caring for keratinous substances, in particular the skin, lips, eyelashes, eyebrows or nails. The- composition may or tnay not be
coloured.
Bach composition can be a foundation, a face powder, an eye shadow, a concealer, a blusher, a lipstick, a lip balm, a lip gloss, a mascara, an eyeliner or a product for making up the body or colouring the skin.
The care composition can be a product for caring for the eyelashes, lips or akin of the body and face, in particular an antisun product.
Compositions in the foam form which are oil-in-water or wax-in-water emulsions comprising a continuous aqueous phase are known.
However, these compoaitions do not always exhibit the gloss desired by consumers, in particular in the case of lipsticks.
The document US 200S/147390 also teaches compositions comprising oils, waxes and a gas in a minimum amount of 2 0%. However, these compositions do not exhibit a satisfactory foam texture.
A search is chus underway to obtain compositions which exhibit a normal texture, in the foam form, and which exhibit a satisfactory gloss, via the incorporation of a certain amount of oils which make it possible to contribute chese gloss properties.
A search is also underway to formulate compositions comprising a high concent of volatile or nonvolatile

oils ox~ organic 'solvents, BO as to improve the hold and/or the reaistahce to water or to sebum and/or the transfer-free properties of the said compositions.
In addition, the compositions in the foam form must exhibit good stability over time, in particular in terms of homogeneity and appearance of the product.
It is an aim of the present invention to provide another formulation route tor a composition for coating keratinous substances which exhibits a foam texture.
More specifically, a subject-matter of the invention is a cosmetic composition in the foam form comprising a continuous oily phase and at least one structuring agent for the oily phase chosen from polymeric structuring agents.
The term "composition in the foam form" is understood to raeari a composition comprising a gae phase (for example air) in the form of bubbles; another certn is "composition expanded in volume".
The composition in the foam form exhibits a light cextura and is easy to withdraw and to spread over keratinous substances.
Another subject-matter of the invention is a method for coating keratinous substances, comprising the application, to the said keratinous substances, of at least one layer of at least one cosmetic composition in the foam form comprising a continuous oily phase and at least one structuring agent for the oily phase chosen from polymeric structuring agents.
The method for coating keratinous substances according to the invention consists in applying the composition in the foam form to keratinous substances; it differs from the processes of the prior art in that the foam is

not formed in situ on the keratinous substances, that is to say that the foam is not created after application of the said composition. In particular, a delayed-expansion composition, which is a system in which a "volatile" agent is released or formed in the composition after the latter has been applied Co the keratinous substances, is not involved. Specifically, delayed-expanaion compositions are created after exposure of a gel to atmospheric pressure and/or to shearing and/or to a temperature greater than ambient temperature,
Another subject-matter of the invention is a kit for making up and/or for a non therapeutic care of keratinous substances, comprising:
a composition in the foam form comprising a continuous oily phase and at least one structuring agent for the oily phase chosen from polymeric structuring agents, and
an applicator comprising at least one application-component configured in order to apply the composition to the keratinous substances.
D«n.sitv
The composition in the foam form exhibits in particular a density (dEoara) of leas than or equal to 0.95, preferably of less than or equal to 0,9, better still of lass than or equal to 0,8. The density is preferably greater than or equal to 0.2 and better still greater than or equal to 0.3.
The density is measured according to the following protocol: a container, the volume Vo (cm3) of which is known with an accuracy- of ±0.005 cm3 (Vo being of the order of 10 cm3} , is weighed by means of a precision balance to ± 0.00005 g. Its weight is recorded as Wo (g) . This container is carefully filled with the foam until the container overflows. The surface! of the

container is Chen levelled with a. straight blade in order to obtain a perfectly flat foam surface, The weight w Cg) of the container filled with foam is then measured.
The density' corresponds to the ratio of the density of the composition, calculated as follows:

The degree of expansion in volume corresponds to the amount of gas incorporated in the composition.
The composition in the foam form advantageously exhibits a degree of expansion in volume of greater than or equal to 10% and preferably of lass than 350%.
The degree of expansion in volume can range, for example, from 10% to 300%, preferably from 30% to 250% ar.d better still from 40% to 200%.
It can in particular be defined by the following formula: ,
Degree of expansion in volume =
(Formula Removed)

The density of the composition before expansion in volume is measured according to the method described above for the foam.
Size of the bubble)?;

A3 the composition according to the invention is in the foam form, it comprises gas bubbles, advantageously air bubbles.
In particular, the air bubbles of the composition exhibit a number-average diameter of less than or equal to 5 ram, for example ranging from 0.1 jun to 5 mm, preferably of less than or- equal to 1 ram and better still of less than or equal to 0,8 trail.
The number-average diameter is determined in the following way: the foam is packaged in a pot as soon as it has finished being prepared, while it is still fluid. The size of the bubbles is observed by taking a 'digital photograph of the surface of the pot 24 h after manufacture or, after opening the packaging, after having levelled the surface, by then counting, over a surface area -of approximately 1 cm2, the number of bubbles using the "Saisara" image processing software-ana by determining their number-average diameter.
Solids content
The compositions according to the invention can advantageously exhibit a content of dry matter (or solids content) of greater than or equal to 60% by weight, with respect to the total weight of the composition, preferably of greater than or equal to 6 5% by weight and better still of greater than or equal to 70% by weight, it being possible for the solids content to range up to 100% by weight, with respect to the total weight of the composition.
The concent of dry matter, that is to say the content of nonvolatile matter, can be measured in various ways. .Mention may be made, for example, of the methods by drying in an oven, the methods by drying by .exposure to infrared radiation and the chemical methods by assaying the water accox~d±ng to the Karl Fischer method.

Preferably, the amount of dry matter, commonly referred to as "solids content", of the compositions according co the invention is measured by heating the sample by infrared rays with a wavelength of 2 \m to 3.5 fan. The substances present in the said compositions which have a high vapour pressure evaporate under the effect of this radiation. The measurement of the loss in weight of the sample makes it possible to determine "the solids content" of the composition. Thesa measurements are carried out by means of a Mettler LP16 commercial infrared dryer. This technique is fully described in che documentation of the device supplied by Mettler.
The measurement protocol is as follows:
Approximately 1 g of the composition is spread over a metal dish. The latter, after introduction into the dryer, is subjected to a set temperature of 1206C for one hour. The wet weight of the* sample, corresponding to the starting weight, and the dry weight of the sample, corresponding- to the weight after exposure to the radiation, are measured by means of a precision balance.
The content of dry matter is calculated in the
following way:
Solids content = 100 x (dry weight/wet weight).
Preferably, the composition employed in the method according to the invention, is a leave-in composition.
