The present application relates to a cosmetic composition comprising at least one ester corresponding to formula (I) below:R1COOR2&#x2003;&#x2003;(I)in which R1 represents H or a linear or branched hydrocarbon-based radical, and R2 represents a linear or branched hydrocarbon-based radical, with the proviso that: This composition can be used as a product for caring for and/or making up keratin materials, in particular the skin, the lips and/or the integuments.

Cosmetic composition comprising at least one volatile ester

A composition comprising, in a physiologically acceptable medium, at least one film-forming polymer and at least one thermal transition agent which undergoes a change of state at a transition temperature Tt chosen within a temperature range from 25&#xb0; C. to 80&#xb0; C., the at least one thermal transition agent being insoluble in water maintained at a temperature below the transition temperature, Tt, the at least one film-forming polymer and the at least one thermal transition agent are present in an amount which is sufficient so that the composition is capable of forming a film at the temperature of a keratinous material to which the composition is applied, wherein the film has a resistance (Rc) to hot water (40&#xb0; C.) of less than or equal to 15 minutes and a resistance (Rf) to cold water (20&#xb0; C.) such that Rf&#x2212;Rc&#x2267;8 minutes. The invention also relates to a cosmetic care or make-up process for a keratinous material. The composition makes it possible to obtain a film which is resistant to cold water and which can be removed simply with hot water.

Film-forming cosmetic composition

A composition for coating a keratinous fiber comprising, in a cosmetically acceptable medium, at least one volatile solvent and a nonvolatile fraction comprising: The composition makes it possible to obtain good curling of keratinous fibers, such as eyelashes.

Mascara comprising solid particles

A composition for coating keratinous fibers, comprising, in a cosmetically acceptable medium comprising at least one volatile solvent, a nonvolatile fraction comprising: a) at least one polymer capable of adhering to the keratinous fibers, b) particles which are solid at 25&#xb0; C. chosen from: i) solid particles of a crystalline or semicrystalline material, ii) solid particles of an amorphous material, iii) solid particles of at least one wax having a hardness of greater than or equal to 6.5 MPa iv) and mixtures thereof. The solid particles are present in the composition in an amount such that the volume fraction of the solid particles is less than or equal to 50% of the total volume of the said nonvolatile fraction. The composition can make it possible to obtain good curling of keratinous fibers, such as eyelashes.

A composition for coating keratinous fibers, such as eyelashes or hair, comprising a wax-in-water dispersion comprising, in a cosmetically acceptable medium, a nonvolatile fraction comprising: at least one polymer capable of adhering to the keratinous fibers, particles which are solid at 25&#xb0; C. of a wax chosen from waxes having a melting point of less than 77&#xb0; C. and a hardness greater than or equal to 6.5 MPa. The solid particles are present in the composition in an amount such that the volume fraction of the solid particles of wax is greater than or equal to 50% of the total volume of the nonvolatile fraction of the composition. The composition can make it possible to obtain good curling of keratinous fibers, such as eyelashes.

The invention relates to a nail polish composition comprising at least one liquid organic phase comprising at least one volatile organic solvent, the liquid organic phase being structured by at least one polymer with a weight-average molecular mass of less than or equal to 100 000 comprising a) a polymer backbone having hydrocarbonaceous repeat units which are provided with at least one heteroatom and optionally b) optionally functionalized pendent and/or end fatty chains which have from 6 to 120 carbon atoms and which are bonded to these units. This composition is provided in particular in the form of a nail polish stick.
