Description

EXAMPLES

[0268] A composition according to the invention with a pasty fat (C1) as defined above and a comparative composition without this pasty fat (example 2), as well as a comparative composition without this pasty fat but with another kind of pasty fat (example 3) were prepared and tested for the black intensity thereof.

[0269] Preparation Protocol for Said Compositions

[0270] In a tank, at ambient temperature, all the ingredients below were introduced, with the exception of the acrylic film-forming polymer (DAITOSOL 5000 AD), in a volume of water corresponding to 20% of the total water.

[0271] The mixture obtained was heated to 95 C. and stirred for 20 minutes. The rest of the water was then added and the mixture was homogenized and emulsified for 15 minutes with mechanical stirring (blades+turbine).

[0272] The mixture was then allowed to cool with stirring up to 40 C. The acrylic film-forming polymer (DAITOSOL 5000 AD) was then added.

[0273] The final mixture was homogenized with the blades and allowed to cool to 20 C.

[0274] Cosmetic compositions with and without pasty fat (C1) according to the invention were prepared according to the tables hereinbelow.

[0275] Example 1 according to the invention comprises a pasty fat (C1) as described above, while the comparative example 2 does not comprise a pasty fat (C1) according to the invention, and the comparative example 3 comprises a pasty fat other than the pasty fat (C1) according to the invention.

[0276] It is understood that, within the scope of the present invention, the weight percentages given, for a compound or a family of compounds, are always expressed by weight of dry matter of the compound in question (unless specified otherwise).

[0277] Protocols and Results Relating to Black Intensity

[0278] The mascara composition in example 1 according to the invention and the mascara composition in examples 2 and 3 outside the invention were tested according to a black intensity measurement protocol.

[0279] Black Measurement Protocol

[0280] The apparatus used to measure the black value is Spectro-guide Sphere Gloss/BYK. The apparatus was set to measure the color without the gloss (Gloss OFF and D65/10).

[0281] A film is applied on a glass slide with a 150 m deposit thickness. The mascara deposit is allowed to dry for 24 hours at ambient temperature. Finally, measurement is made with the colorimeter on a dry film with the plastic support of the colorimeter.

[0282] The results obtained are as follows:

TABLE-US-00002 Example 1 Example 2 Example 3 (invention) (comparative) (comparative) L 22.23 22.97 23.43 a 0.24 0.21 0.13 b 0.76 0.82 1.08

[0283] The blackness of the composition comprising the compound C1 (example 1), namely Glyceryl behenate (and) tribehenin (and) glyceryl behenate (Compritol 888 CG ATO (GATTEFOSSE)), is much higher (lower L value) than example 2 which does not contain it.

[0284] The blackness of the composition comprising the compound C1 (example 1) is also much higher (lower L value) than example 3 which does not contain it but contains another kind of pasty fat (Emulium 22).

[0285] The difference in blackness is also visually perceptible.

[0286] Indeed, it can be seen that the composition of example 1 (according to the invention) has a higher blackness in mass in a recipient and also between two glass plates, in comparison with the composition of example 3 (with Emulium 22).
