Definitions

• foundations require the use of an applicator such as a sponge, which rapidly becomes contaminated and must be cleaned very regularly, especially after each application.
• an applicator such as a sponge
• users of foundations are increasingly on the lookout for solid forms in stick, in order to dispense with the sponge-type applicator.
• Such a foundation is easy to use, hygienic and can be applied until all of the product has been used up, unlike a conventional foundation applied with a sponge.
• the surface of the foundation remains smooth, whereas the surface of a product compacted in a case becomes deformed under the pressure of the successive uptakes onto the applicator. Finally, it allows a uniform make-up effect to be obtained.
• the polymer in the composition of the invention advantageously comprises a number of fatty chains which represents from 40% to 98% of the total number of units containing a hetero " atom and of fatty chains, and better still from 50% to 95%.
• the nature and proportion of the units containing a hetero atom depends on the nature of the liquid fatty phase and is, in particular, similar to the nature of the fatty phase.
• the fibres may or may not be surface-treated and may or may not be coated, in particular with a view to making them hydrophobic.
• coated fibres which can be used in the invention, mention may be made of polyamide fibres coated with copper sulphide for an antistatic effect (for example the R-STAT fibres from Rhodia) or another polymer allowing a particular organization of the fibres (specific surface treatment) or a surface treatment which induces colour/hologram effects ("Lurex" fibre from Sildorex, for example).
• Flat multilayer fibres having goniochromatic properties may also be used.
• Such fibres are disclosed in particular in the document EP-A- 921217. They are formed from alternating layers of polyamide and polyester, in particular polyester terephthalate.
• the hardness of the composition according to the invention is such that the composition is advantageously self-supporting and can disintegrate easily to form a satisfactory deposit on the skin and/or the lips and/or superficial body growths.
• the 5 composition of the invention has good impact strength.
• the hardness of the composition in stick form, together with its shear strength, increases as the amount of fibre increases.
• the amphiphilic compound(s) which can be used in the composition of the invention comprise a lipophilic part linked to a polar part, the lipophilic part comprising a carbon-based chain containing at least 8 5 carbon atoms, in particular from 18 to 32 carbon atoms and better still from 18 to 28 carbon atoms.
• the polar part of this or these amphiphilic compound(s) is preferably the residue of a compound chosen from alcohols and polyols containing from 1 to 12 hydroxyl groups, and polyoxyalkylenes comprising at least 2 oxyalkylene units and containing from 0 to 20 o oxypropylene units and/or from 0 to 20 oxyethyiene units.
• the liquid fatty phase of the composition advantageously contains more than 30% and better still more than 40% of liquid oil(s) having a chemical nature close to the one of the skeleton of the structurant polymer, and for example from 50% to 100%.
• the liquid fatty phase structured with a polyamide-type skeleton contains a high quantity, i.e. greater than 30% and better still greater than 40% relative to the total weight of the liquid fatty phase and for example from 50% to 100%, of apolar and more especially hydrocarbon-based oil or mixture of oils.
• hydrocarbon-based oil means an oil essentially comprising carbon and hydrogen atoms, optionally with one or more hydroxyl, ester or ether groups.
• the structured oils are preferably apolar oils and more especially an oil or a mixture of oils of the hydrocarbon-based type of mineral or synthetic origin, chosen in particular from hydrocarbons, especially alkanes such as sesam oil, isoparaffins including isododecane, and squalane, and mixtures thereof. These oils are advantageously combined with one or more phenylsilicone oils.
• these volatile solvents improve, in particular, the staying power or long wearing over time of the composition on the skin, the lips or superficial body growths.
• the composition advantageously contains at least one volatile solvent, and better still a volatile oil.
• This solvent may be chosen from hydrocarbon-based solvents, silicone solvents optionally comprising alkyl or alkoxy groups that are pendent or at the end of a silicone chain, fluoro solvents and mixtures thereof.
• volatile solvents which can be used in the invention, mention may be made of linear or cyclic silicone oils having a viscosity at room temperature of less than 8 cSt and in particular containing from 2 to 7 silicon atoms, these silicones optionally comprising alkyl or alkoxy groups containing from 1 to 10 carbon atoms.
• composition according to the invention can be in the form of a tinted dermatological composition or a care composition for keratin materials such as the skin, the lips and/or superficial body growths, in the form of an antisun composition or body hygiene composition in particular in the form of a deodorant product or make-up-removing product in stick form. It can be used in particular as a care base for the skin, superficial body growths or the lips (lip balms, for protecting the lips against cold and/or sunlight and/or the wind, or care cream for the skin, the nails or the hair).
• the nacreous pigments may be chosen from white nacreous pigments such as mica coated with titanium or with bismuth oxychloride, coloured nacreous pigments such as titanium mica with iron oxides, titanium mica with, in particular, ferric blue or chromium oxide, titanium 5 mica with an organic pigment of the type mentioned above, as well as nacreous pigments based on bismuth oxychloride. They can represent from 0.1% to 20% relative to the total weight of the composition, and better still from 0.1% to 15%, if they are present, and may or may not be surface-treated. 0
• the composition can optionally contain one or more waxes to improve the structuring in stick form, although this rigid form can be . obtained in the absence of wax.
