Description

[0001] Description

[0002] Title: Process for making up keratin materials, comprising the application of at least one acetoacetate-functional acrylic copolymer and a hydrophobic crosslinking agent

[0003] Technical field

[0004] The present invention relates more particularly to the cosmetic field of keratin materials, and especially to that of making up the skin and / or eyelashes and / or eyebrows.

[0005] It thus aims to provide a process for making up keratin materials, comprising at least the application to said keratin materials of at least two distinct compositions (A) and (B).

[0006] Another subject of the invention is a kit for making up keratin materials, comprising at least two separately packaged compositions (A) and (B).

[0007] Prior art

[0008] Cosmetic products conventionally require the use of one or more film-forming polymers in order to obtain a quality deposit of these products on keratin materials, and in particular to satisfy the expectations detailed below.

[0009] Thus, in the field of skin makeup, it is especially expected that the deposit formed will not transfer on contact with the fingers or clothing.

[0010] It must also exhibit good stability on contact with water, especially rain or when showering or else perspiration, and also on contact with fats, such as sebum, for example. Moreover, this deposit must be comfortable and even glossy.

[0011] For this purpose, dispersions of polymer particles of nanometric size are used as a filmforming agent in makeup products such as mascaras, eyeliners and eyeshadows, and more particularly in their organic and, especially, oily phases.

[0012] Thus, FR 2 741 530, for example, proposes for this purpose, for the temporary dyeing of keratin fibres, the use of a dispersion of film-forming polymer particles including at least one acidic function and at least one pigment dispersed in the continuous phase of said dispersion. The colourings obtained via this dyeing method are not always satisfactory in terms of persistence, notably with respect to shampoo washing. Specifically, in general, these polymers do not afford deposits on keratin materials that satisfy all the abovementioned requirements, namely very good resistance to sebum and to water, in particular to hairshampoos, which make it possible to adjust the gloss or invisibility qualities and which, in the case of haircare use, provide a very satisfactory styling hold.

[0013] EP 3 250 177 Al describes the use of acetoacetyl compounds in the field of keratin fibres. The keratin materials treated with said acetoacetyl compounds do not always give satisfactory results, especially in terms of persistence.

[0014] These documents do not make it possible to obtain deposits that are non-sticky, transfer little, are comfortable, and are long-lasting.

[0015] Disclosure of the invention

[0016] There is thus still a need for cosmetic compositions intended for application to the skin and / or eyelashes and / or eyebrows which make it possible to obtain a deposit that is non-sticky, which transfers little, if at all, and which is glossy, comfortable and long-lasting. There is also still a need for compositions which are resistant to various mechanical and chemical challenges, for example makeup-removing compositions such as biphasic waters, or to sebum, and more particularly to sebum.

[0017] There also remains a need for compositions that afford qualities of gloss and of colour persistence.

[0018] The present invention is specifically directed to meeting some or all of these needs.

[0019] Summary of the invention

[0020] These problems are solved by the implementation of a process for making up keratin materials, especially the skin and / or eyelashes and / or eyebrows, comprising at least the application to said keratin materials of at least two distinct compositions (A) and (B):

[0021] said composition (A) comprising at least:

[0022] i) at least one acetoacetate-functional copolymer, called CP, comprising repeating units derived from at least one monomer of formula (I) below:

[0023] [Chem 1]

[0024]

[0025] in which:

[0026] - Rarepresents a hydrogen atom or a linear or branched (Ci-C4)alkyl group;

[0027] - Rband Rc, which are identical or different, represent a hydrogen atom or a linear or branched (Ci-C4)alkyl group;

[0028] - Rdrepresents a linear or branched (Ci-C4)alkyl group; and

[0029] - L represents a linear or branched (Ci-Ce)alkylene group or a cycloalkylene group, and at least one monomer, preferably at least two monomers chosen from C1-C4 alkyl acrylates, C1-C4 alkyl methacrylates and mixtures thereof;

[0030] ii) at least one polyol;

[0031] iii) at least one alkyl acetate comprising from 2 to 4 carbon atoms;

[0032] iv) at least one volatile oil, preferably a hydrocarbon and / or silicone oil;

[0033] v) at least one monoalcohol comprising from 2 to 4 carbon atoms; and

[0034] said composition (B), which is anhydrous and comprises at least:

[0035] vii) a crosslinking agent chosen from hydrophobic (poly)amine compounds;

[0036] said composition (A) and / or said composition (B) comprising vi) at least one particulate colourant.

[0037] The inventors have thus found, surprisingly, that the application to the keratin materials of the ingredients i) to vii) makes it possible to improve the stability of the coloured deposit on the keratin materials treated with this combination.

[0184] The sizes are measured by static light scattering using a commercial MasterSizer 3000® particle size analyzer from Malvern, which makes it possible to determine the particle size distribution of all of the particles over a wide range which may extend from 0.01 pm to 1000 pm. The data are processed on the basis of the standard Mie scattering theory. This theory is the most suitable for size distributions ranging from the submicronic to the multimicronic;it makes it possible to determine an “effective” particle diameter. This theory is notably described in the publication by Van de Hulst, H.C., Light Scattering by Small Particles, Chapters 9 and 10, Wiley, New York, 1957.

[0272] The first and second cosmetic compositions included in the makeup kit of the invention may be applied in particular to the eyelashes and / or the eyebrows, using a sponge, a flocked applicator, a coarse brush, a fine brush, a comb, a threaded stem or a pen equipped with a notched wheel. They can also be applied with the fingers.

[0273] In the present case, the first composition may be applied using any applicator provided that it allows a deposit localized on a portion of the length of the keratin fibre and, when it is an eyelash, over at most 2 / 3 of its length.

[0274] The threaded stem may be made of plastic or metal or any other suitable material.

[0275] The pen equipped with a notched wheel is more particularly described in patent application US 5851019 or FR 2588733.

[0276] This pen allows precise metering of the product to be applied at the outlet of the pen after actuation of a notched wheel or of a push-button which advances a piston with each rotation / press.

[0277] In actual fact, the keratin materials can be made up according to two processes. The first route involves multiple actions by the user, namely at least two steps, the first consisting of the application of the "basecoat" composition and the second consisting of the application of the "topcoat" composition completely or partially on the first "basecoat" composition and on the keratin materials.

[0278] According to a particularly advantageous embodiment, this packaging article is provided with two distinct applicators.

[0279] The second route involves premixing the two compositions, just before applying the resulting composition on the keratin materials.

[0280] Whatever the route chosen by the user, the packaging kit comprises two separate compartments or reservoirs for each of the compositions (A) and (B), each reservoir or compartment being closed by a closing member, and optionally at least one suitableapplicator, preferably two applicators. It should be noted that the packaging kit may also comprise means for combining the two compositions before application, such as a container and a stirrer.

[0281] The applicator may optionally be rigidly connected to the container. Advantageously, the applicator is rigidly connected to a stem which, itself, is rigidly connected to the closing member.

[0282] The closing member can be coupled to the container by screwing. Alternatively, the coupling between the closing member and the container is done other than by screwing, in particular via a bayonet mechanism, by click-fastening or by gripping. The term “click-fastening” is understood in particular to mean any system involving the crossing of a bead or cord of material by elastic deformation of a portion, in particular of the closing member, followed by return to the elastically unconstrained position of said portion after the crossing of the bead or cord.

[0283] The container, advantageously comprising the compartment(s) or reservoir(s), and also the mixing container, may be at least partly made of thermoplastic material. Mention may be made, as examples of thermoplastic materials, of polypropylene or polyethylene.

[0284] Alternatively, the containers are made of non-thermoplastic material, notably of glass or metal (or alloy).

[0285] The containers are preferably equipped with a wiper positioned in the vicinity of at least one opening of the container. Such a wiper makes it possible to wipe the applicator and optionally the stem to which it may be rigidly connected. Such a wiper is described, for example, in patent FR 2792618.

[0286] Throughout the description, including the claims, the terms “between ... and ...”, and “ranging from ... to ...” should be understood as meaning with endpoints included, unless otherwise specified.

[0287] The invention is illustrated in greater detail in the examples that follow. The amounts are indicated as weight percentages.

[0288] ExampleCompound 1: Preparation of isobutyl acrylate / tert-butyl acrylate / acetoacetoxy ethyl methacrylate (25 / 65 / 10) copolymer

[0289] 62.5 g of isobutyl acrylate, 162.5 g of tert-butyl acrylate,

[0290] 25 g of acetoacetoxyethyl methacrylate, 2.5 g of the radical initiator Trigonox T21S and 360 g of an isododecane / ethyl acetate solvent (50 / 50) are introduced into a 1 L pilot reactor. The medium is degassed with argon and then heated to 90°C with stirring. The reaction medium is kept for 7 hours at 90°C, then stripping with 300 mL of isododecane is performed to remove the residual monomers.

[0291] At the end of the reaction, an isobutyl acrylate / tert-butyl acrylate / acetoacetoxyethyl methacrylate copolymer is obtained in solution in isododecane.

[0292] Compound 2: Preparation of isobornyl acrylate / acetoacetoxyethyl methacrylate (90 / 10) copolymer

[0293] 135 g of isobornyl acrylate, 30 g of acetoacetoxyethyl methacrylate, 100 g of an isododecane / ethyl acetate (70 / 30) solvent and 100 g of isododecane alone are introduced into a 1 L pilot reactor.

[0294] The medium is degassed with argon and then heated to 90°C with stirring (100 rpm).

[0295] Once the reaction medium reaches the temperature of 90°C, 338 g of a mixture composed of 200 g of isododecane, 135 g of isobornyl acrylate and 3 g of Trigonox 21 S initiator are poured in over one hour.

[0296] The reaction medium is kept for 7 hours at 90°C. The next day, the reaction medium is stripped with 2 x 200 mL of cold isododecane.

[0297] At the end of the reaction, an isobutyl acrylate / acetoacetoxyethyl methacrylate copolymer is obtained in solution in isododecane.

[0298] Preparation of compositions A, AZ and B

[0299] Compositions A, AZ and B are prepared on the basis of the contents indicated in Tables 1 and 2 below. The contents are expressed as weight percentages relative to the total weight of the composition under consideration.

[0300] [Table 1]

[0301]

[0302]

[0303] [Table 2]

[0304]

[0305] The compositions are prepared by simple mixing of the ingredients detailed in the tables above using a SpeedMixer® (Hauschild DAC 150.1 FVZ) (10 grams, 1 cycle, 2 minutes 30 seconds, 2500 rpm).

[0306] Formulations to be applied

[0307] Each of composition (A) according to the invention and comparative composition (AZ) were mixed with composition (B) in a 1 : 1 mass ratio using a SpeedMixer® (Hauschild DAC 150.1 FVZ) (10 grams, 1 cycle, 2 minutes 30 seconds, 2500 rpm).

[0308] Application

[0309] Each formula ((A) + (B) and (AZ) + (B)) was applied with a spatula to a Supplale® support (SOUDOTIQUE reference RLXSUPNOIR, format: 30 000 x 1200 mm x 0.7 mm) with dimensions of 2 cm x 5 cm, at a rate of 0.02 g / cm2

[0310] Drying takes place at room temperature for 24 hours.

[0311] Resistance to biphasic water

[0312] Once dry, the SUPPLALE® supports thus treated are immersed in biphasic water (La Roche Posay Respectissime waterproof eye makeup remover) for 3 minutes.At the end of immersion, the SUPPLALE® supports were rubbed against a towel (Chicopee® VERACLEAN™ Polish Plus 34><32cm) 10 times with a mass of 660 g, over a length of 34 cm.

[0313] In order to measure the stability of the colour, a colour difference (delta E) is measured between the initial deposit and the deposit after immersion in biphasic water.

[0314] Sebum resistance

[0315] Once dry, the SUPPLALE® supports treated according to the application protocol are immersed in artificial sebum for 15 minutes.

[0316] At the end of immersion, the SUPPLALE® supports were rubbed against a towel (Chicopee® VERACLEAN™ Polish Plus 34><32cm) 10 times with a mass of 660 g, over a length of 34 cm.

[0317] In order to measure the stability of the colour, a colour difference (delta E) is measured between the initial deposit and the deposit after immersion in artificial sebum.

[0318] Persistence protocol

[0319] The persistence of the colour of the deposits was evaluated in the CIE L*a*b* system, using a Konica CM 700d® Spectrophotometer from Minolta (illuminant D65, angle 10°, specular component included).

[0320] In this L*a*b* system, L* represents the intensity of the colour, a* indicates the green / red colour axis and b* the blue / yellow colour axis.

[0321] The persistence of the colour of the deposits is evaluated by the colour difference AE between the coloured Supplale® supports before challenge, then after undergoing challenge, that is to say immersion in biphasic water or in artificial sebum, according to the protocol described above. The lower the AE value, the more persistent the colour with respect to the challenges.

[0322] The AE value is calculated according to the following equation:

[0323] [Math 1]

[0324]

[0325] In this equation, L*a*b* represent the values measured after colouring the SUPPLALE® supports and after having undergone a challenge, and Lo*ao*bo* represent the values measured after colouring the SUPPLALE® supports but before challenge.

[0326] Results

[0327] The evaluation results are summarized in Table 3 below:

[0328] [Table 3]

[0329]

[0330] It is apparent that the application of formula ((A)+(B)) comprising an acetoacetate-functional copolymer according to the invention makes it possible to obtain a significantly improved sebum persistence relative to the application of comparative formula ((AZ)+(B)) comprising an acetoacetate-functional copolymer outside the invention.
