Description

EXAMPLES

[0288] A composition according to the invention with a polyester such as defined hereinabove as well as a comparative composition without this polyester were prepared and tested for their volume effect, as well as their properties for application, stability and makeup.

[0289] Preparation Protocol for Said Compositions

[0290] The compositions were prepared according to a method with the rotor stator.

[0291] In a first step, a bentone gel was prepared according to the following protocol: Isododecane was weighed in a beaker then placed in the Rayneri stirrer with dispersing (speed=400 to 600 rpm according to the quantity of solvent) at ambient temperature. Then, the modified hectorite was added by sprinkling into the isododecane, under stirring, still at ambient temperature.

[0292] Then, the propylene carbonate was added and the whole was allowed to stand for about 45 minutes at ambient temperature.

[0293] Then, the waxy mixture was prepared by melting the waxes in a double-shell skillet by connecting with the oil bath until melting of the waxes (bath setting 120° C.). The whole was placed under Rayneri stirring with the rotor stator as soon as the waxes were melted in order to homogenize.

[0294] The pigments were then added to the waxy mixture, still under stirring with the rotor stator, at about 1500-1700 rpm. The oil bath setting was lowered in order to obtain 95° C. in the skillet and the whole was allowed to stand for 20 to 30 minutes.

[0295] The bentone gel (prepared as indicated hereinabove) was added, under rotor stator stirring, and the stirring was increased to 2000 rpm. The temperature of the mixture dropped and was left until homogenization of the temperature at 85° C.

[0296] The setting of the oil bath was then lowered to 25° C. and the rotor stator stirring was removed and switching to “step by step” blade with the speed reducing adapter (Rayneri setting 400 rpm).

[0297] Starting at 40° C., the additives (micro dispersion of waxes, alcohol, active materials, etc.), were added under Rayneri by switching to stirring with dispersing in order to correctly homogenize (Rayneri speed 700 to 1000 rpm). Finally, the whole was again placed under “step by step” blade in order to continue cooling to 25° C.

[0298] Cosmetic compositions with and without polyester according to the invention were prepared according to the tables hereinbelow.

[0299] Example 1 according to the invention comprises a polyester, while the comparative example 2 does not comprise polyester according to the invention.

[0300] Makeup Tests

[0301] The compositions 1 (invention) and 2 (comparative) were then tested for their makeup properties.

[0302] In particular, it was observed that the composition according to the invention is significantly more charging and that the progression of the deposit is better compared to the comparative composition without polyester.

[0303] As such, the adding of the polyester according to the invention makes it possible to improve the volume effect on the eyelashes compared to a composition without polyester.

[0304] Moreover, additional tests were carried out with regards to the stability to friction, stability to water and stability to squalene, as well as the removal of the is mascara.

[0305] It was observed that the composition according to the invention has characteristics similar to a conventional waterproof mascara. In particular, the composition of the invention has stability properties that are identical to those of a conventional waterproof mascara and, likewise, the composition of the invention has makeup removal properties that are identical to those of a conventional waterproof mascara.
