Description

The present invention relates to a cosmetic product comprising at least

  at least two compositions that can be applied successively to the skin of the face as well as the body, on the lower and upper eyelids, on the lips and on the integuments such as nails, eyebrows, eyelashes or hair. The present invention relates to

  also a process for makeup of the face and the body using these two compositions.

  Each composition can be a foundation, a blush, an anti-ring product, a blush, a loose or compacted powder, a lipstick, a lip balm, a lip gloss, a pencil lips or eyes, a mascara, an eyeliner, a nail polish or a product for body makeup or skin coloring.

  An object of the present invention is to provide a composition that is both good and bright.

  Poor behavior over time can result in particular in poor color retention and / or poor gloss performance over time. This poor performance may be characterized by a change in color (turning, paling) generally as a result of an interaction with sebum and / or sweat secreted by the skin in the case of foundation and make-up, or of an interaction with saliva in the case of lipsticks, or a decrease in gloss, in the case of a nail polish. This forces the user to remix himself very often, which can be a waste of time.

  For products of good resistance and non-transfer, it is often used volatile oils or polymers dispersed in a volatile solvent. However, these products are not bright enough. It has therefore been envisaged a cosmetic product comprising two compositions, a first containing a polymer dispersed in a volatile solvent, to which a second glossy and greasy composition is applied (FR-A-2823101). The holding of the color of the makeup obtained with these compositions is good, but the disappearance of the second composition during the day when it is worn causes a loss of gloss, desired by the consumer.

  The company Kose has also proposed in its patent application JR-A-05221 829 the use of a gel based perfluorinated materials, which is applied to a lipstick film so as to avoid its transfer to other surfaces, the gel being incompatible with the lipstick film.

  It is also possible to cite patent application WO-A-97/17057 which describes a method for increasing the holding and non-transfer properties of applying two compositions to one another. The composition to be applied has a Hildebrarid overall solubility parameter of less than 8.5 (cal / cm 3) -1, and the composition to be applied as an overlayer must contain oils whose calculated partition coefficient ClogP is at least equal to 13.

  US-A-6,001,374 proposes a makeup system consisting of using a composition containing an alcohol-soluble and water-insoluble resin, which can be applied as a basecoat or overcoat, and having the advantage of not staining an object put in contact with makeup and to resist water and friction, while having a certain brilliance. However, this composition contains a water-soluble alcohol, in particular ethanol, a compound which is irritating, desiccating for the skin and more particularly for the lips, and which is particularly uncomfortable when the skin or the lips are damaged in the WO application. 02/067877, there is described a method for improving the aesthetic properties of a non-transfer composition comprising applying a second composition to a non-transfer composition film. The second composition must not interact chemically with the non-transfer composition in order not to alter its cosmetic properties. Some products described in this document have an unpleasant smell and are sticky. Other products are not bright enough.

  The color L * pa * Ob * 0 of the support is measured using a MINOLTA CR 300 colorimeter, on the acrylic coating side.

  The support thus prepared is preheated on a heating plate maintained at a temperature of 40 ° C. so that the surface of the support is maintained at a temperature of 33 ° C.

  While leaving the support on the hot plate, the composition is applied to the entire non-adhesive surface of the support (i.e., on the surface of the acrylic coating) by spreading it with a brush to obtain a deposit of the composition of about 15 pm and then allowed to dry for 10 minutes.

  After drying, the color L * a * b * of the film thus obtained is measured.

  The color difference AE1 is then determined between the color of the film with respect to the color of the bare substrate by the following relation.

  AE1 = (L * _Lo *) 2 + (a * - ao *) 2 + (b * - bo *) 2 The support is then adhered by its adhesive side (adhesive side of the foam layer) on an anvil of a diameter of 20 mm and provided with a screw thread. A test piece of the support / deposit assembly is then cut using a punch with a diameter of 18 mm. The anvil is then screwed onto a press (MANUAL STATIF IMADA SV-2 from SOMECO) equipped with a dynamometer (IMADA DPS-20 from SOMECO).

The first mark is placed on 20 pl of water and on the second mark 10 ul of refined sunflower oil (sold by the company LESIEUR).

  The white paper is placed on the base of the press and the specimen placed on the square of the paper strip is pressed at a pressure of approximately 300 g / cm 2 exerted for 30 seconds. Then the press is raised and the test piece is placed again just after the second line (hence beside the box), a pressure of approximately 300 g / cm 2 is again made and is moved rectilinearly on contact. The paper was made at a speed of 1 cm / sec. along the entire length of the web so that the specimen passed through the water and oil deposits.

  After removal of the specimen, a portion of the deposit was transferred to the paper. The color L * ', a *', b * 'of the deposit remaining on the test piece is then measured.

  The color difference AE2 is then determined between the color of the deposit remaining on the specimen relative to the color of the bare support by the following relation.

  AE2 = (L *, _ Lo *) 2 + (a * -. Ao *) 2 + (b *, _ bo *) 2 The strength of the composition, expressed as a percentage, is equal to the ratio: 100 X AE2 / AE1 Measurement is carried out on 6 supports in succession and the value of transfer corresponds to the average of the 6 measurements obtained with the 6 supports.
