Description

Title of the invention: A method for making up keratinous materials comprising the application of at least one acrylic copolymer with acetoacetate groups and a hydrophobic crosslinking agent. Technical field

[0001] The present invention relates more particularly to the cosmetic field of keratinous materials, and in particular to that of makeup for the skin and / or eyelashes and / or eyebrows.

[0002] It aims to propose a process for making up keratinous materials comprising at least the application on said keratinous materials of at least two distinct compositions (A) and (B).

[0003] The invention also relates to a makeup kit for keratinous materials comprising at least two compositions (A) and (B) packaged separately. Prior art

[0004] Cosmetic products classically require the implementation of one or more film-forming polymers in order to obtain a quality deposit of these products on keratinous materials, and in particular giving satisfaction to the expectations detailed below.

[0005] Thus, in the field of skin makeup, it is particularly expected that the deposit formed will not transfer upon contact with fingers or clothing.

[0006] It must also exhibit good resistance to contact with water, particularly rain or during showering, as well as perspiration and grease, such as sebum. Furthermore, this coating must be comfortable and even glossy.

[0007] To achieve this, it is used in makeup products such as mascaras, eyeliners, eyeshadows, and more particularly in their organic and especially oily phases, dispersions of nanometric polymer particles, as a film-forming agent.

[0008] Thus, for example, document FR 2 741 530 proposes, for this purpose, for the temporary coloring of keratin fibers, the use of a dispersion of film-forming polymer particles comprising at least one acid function and at least one pigment dispersed in the continuous phase of said dispersion. The colors obtained by this coloring method are not always satisfactory in terms of permanence, particularly with shampooing. In fact, generally speaking, these polymers do not do not allow access to deposits on keratinous materials which satisfy all the aforementioned requirements, namely very good resistance to sebum and water, particularly to shampoos for hair, which allow adjustment of shine or invisibility qualities and which, in the case of hair use, provide very satisfactory hold of styling.

[0009] Document EP 3 250 177 A1 describes the use of acetoacetylated compounds in the field of keratin fibers. Keratin materials treated with said acetoacetylated compounds do not always give satisfactory results, particularly in terms of durability.

[0010] These documents do not allow for obtaining non-sticky deposits, which transfer little, are comfortable, and are persistent. Description of the invention

[0011] There therefore remains a need for cosmetic compositions intended for application to the skin and / or eyelashes and / or eyebrows which provide a non-sticky deposit, which transfers little or not at all, is shiny, comfortable, and long-lasting.

[0012] There also remains a need for compositions that are resistant to various mechanical and chemical aggressions, for example makeup-removing compositions such as two-phase waters, or sebum, and more particularly sebum.

[0013] There also remains a need for compositions that provide qualities of brilliance and color retention.

[0014] The present invention is specifically aimed at meeting all or part of these needs. Summary of the invention

[0015] These problems are solved by implementing a process for making up keratinous materials, in particular skin and / or eyelashes and / or eyebrows, comprising at least the application to said keratinous materials of at least two distinct compositions (A) and (B): - said composition (A) comprising at least: i) at least one copolymer with acetoacetate function(s) called CP, comprising repeating units derived from at least one monomer of the following formula (I):

The data are processed based on the classical Mie scattering theory. This theory is best suited for size distributions ranging from submicron to multimicron, and it allows for the determination of an "effective" particle diameter. This theory is notably described in Van de Hulst, H.C., "Light Scattering by Small Particles," Chapters 9 and 10, Wiley, New York, 1957.

[0182] [Chem.10] (I)

[0183] in which: - Ra represents a hydrogen atom or a (Ci-C4)alkyl group, linear or branched; - Rb and Rc, identical or different, represent a hydrogen atom or a (Ci-C4)alkyl group, linear or branched; - Rd represents a (Ci-C4)alkyl group, linear or branched; and - L represents a linear or branched (Ci-C6)alkylene group, or cycloalkylene, and at least one monomer, preferably at least two monomers chosen from CrC4 alkyl acrylates, CrC4 alkyl methacrylates and mixtures thereof; ii) at least one polyol; iii) at least one alkyl acetate comprising 2 to 4 carbon atoms; iv) at least one volatile oil, preferably hydrocarbon; and v) at least one monoalcohol comprising 2 to 4 carbon atoms; - at least one second compartment separate from said first compartment, and containing at least the composition (B), anhydrous, comprising: vii) a crosslinking agent selected from hydrophobic (poly)amine compounds;

[0185] Any type of applicator can be used for the deposition of the first and / or second composition.

[0186] The respective applicators of the first and second composition may be identical or distinct.

[0187] According to one embodiment of the invention, the first and second compositions can be applied by means of two separate applicator portions of the same applicator.

[0188] According to another variant, the makeup kit according to the present invention comprises one or more means of applying the first and second compositions.

[0189] The first and second cosmetic compositions included in the makeup kit of the invention can in particular be applied to the eyelashes and / or eyebrows, using a sponge, a flocked applicator, a brush, a paintbrush, a comb, a threaded rod or a pen equipped with a notched wheel. They can also be applied with a finger.

[0190] In this case, the first composition can be applied using any applicator provided that it allows localized deposition on part of the length of the keratin fiber and, when it is a lash, on no more than 2 / 3 of its length.

[0191] The threaded rod may be made of plastic or metal or any other suitable material.

[0192] The pen with a notched wheel is more particularly described in US application 5851019 or FR 2588733.

[0193] This pen allows precise dosing of product to be applied at the outlet of the pen after actuating a notched wheel or a push button which advances a piston with each rotation / pressure.

[0194] In reality, the makeup of keratinous materials can be carried out according to two methods. The first method consists of a multi-step process 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 in whole or in part over the first composition called "basecoat" and over the keratinous materials.

[0195] According to a particularly advantageous embodiment, this packaging article is provided with two separate applicators.

[0196] The second method consists of pre-mixing the two compositions, just before applying the resulting composition to the keratinous materials.

[0197] Regardless of the method chosen by the user, the packaging kit comprises two separate compartments or reservoirs for each of compositions (A) and (B), each reservoir or compartment being closed by a closure element, and optionally at least one suitable applicator, preferably two applicators. It should be noted that the packaging kit may also include means for combining the two compositions before application, such as a container and a stirrer.

[0198] The applicator may optionally be integral with the container. Advantageously, The applicator is attached to a rod which, in turn, is attached to the closing element.

[0199] The closure element can be coupled to the container by screwing. Alternatively, the coupling between the closure element and the container is achieved by means other than screwing, in particular via a bayonet mechanism, by snap-fitting, or by clamping. "Snap-fitting" refers in particular to any system involving the passage of a bead or a band of material by elastic deformation of a portion, in particular of the closure element, and then by the return of said portion to its elastically unconstrained position after passing the bead or band.

[0200] The container, advantageously comprising the compartment(s) or reservoir(s), as well as the mixing container, may be at least partially made of thermoplastic material. Examples of thermoplastic materials include polypropylene and polyethylene.

[0201] Alternatively, the containers are made of non-thermoplastic material, in particular glass or metal (or alloy).

[0202] The containers are preferably equipped with a wringer located near at least one opening of the container. Such a wringer allows the applicator and Optionally, the rod to which it may be attached. Such a wringer is described, for example, in patent FR 2792618.

[0203] Throughout the description, including the claims, the expressions "between ... and ..." and "ranging from ... to ..." shall be understood to include bounds, unless otherwise specified.

[0212] Once the reaction medium reaches a temperature of 90 °C, 338 g of a A mixture composed of 200 g of isododecane, 135 g of isobornyl acrylate, and 3 g of Trigonox 21S primer, is cast in one hour.

[0213] The reaction medium is maintained at 90 °C for 7 hours. The following day, the reaction medium is stripped with 2 x 200 mL of cold isododecane.

[0214] As a result of the reaction, an isobutyl acrylate / acetoacetoxyethyl methacrylate copolymer is obtained in solution in isododecane. Preparation of compositions A, AZ and B

[0215] Compositions A, AZ and B are prepared from the contents indicated in Tables 1 and 2 below. The contents are expressed as a percentage by weight, relative to the total weight of the composition in question.

[0216] [Tables 1] Ingredients Composition (A) according to the invention Comparative Composition (A) Compound 1: Isobutyl Acrylate / Tet-Butyl Acetyl Acetoxyethyl Methacrylate (25.76 5 / 10) copolymer in isododecane 42.7 (27.52 active material) Compound 2: Isobutyl Acrylate / Acetoxyethyl Methacrylate (90 / 10) copolymer in isododecane 42.7 (27.52 active material) Butyl Acetate 19 19 Hexylene glycol 13.72 13.72 Isododecane qs 100 qs 100 Black Iron Oxide 10 10 Ethanol 10.16 10.16

[0217] [Tables2] Ingredients Composition (B) according to the invention Bis-cetearyl Amodimethicone (Miwntiw Performance Matenoh) 60 Isododecane 40

[0218] The compositions are prepared by simply mixing 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). Formulas to apply

[0219] Each of the compositions (A) according to the invention and (AZ) comparative were mixed with composition (B) in a mass ratio 1:1, using a SpeedMixer® Hauschild DAC 150.1 FVZ) (10 grams, 1 cycle, 2 minutes 30 seconds, 2500 rpm). Application

[0220] Each formula ((A) + (B)) and ((AZ) + (B)) was applied with a spatula to a supplale® support (SOUDOTIQUE reference RLXSUPNOIR, format: 30000 X 1200 MM X 0.7 MM) of dimensions 2 cm x 5 cm, at a rate of 0.02 g / cm2.

[0221] Drying takes place at room temperature for 24 hours. Two-phase water resistance

[0222] Once dry, the Supplale® thus treated are immersed in biphasic water (La Roche Posay Respectissime waterproof eye makeup remover) for 3 minutes.

[0223] Once the immersion is finished, the Supplale® are rubbed against a towel (Chicopee® VERACLEAN™ Polish Plus 34 x 32cm) 10 times with a mass of 660 g, over a length of 34 cm.

[0224] To measure color fastness, a ΔE (delta E) is measured between the initial deposit and the deposit after immersion in two-phase water. Sebum resistance

[0225] Once dry, the Supplale® treated according to the application protocol are immersed in artificial sebum for 15 minutes.

[0226] Once the immersion is finished, the Supplale® are rubbed against a towel (Chicopee® VERACLEAN™ Polish Plus 34 x 32cm) 10 times with a mass of 660 g, over a length of 34 cm.

[0227] To measure color retention, a color difference (delta E) is measured between the initial deposit and the deposit after immersion in artificial sebum. Persistence Protocol

[0228] The persistence of the color of the deposits was evaluated in the CIE L*a*b* system, using a Minolta Konica CM 700d® Spectrophotometer (illuminant D65, angle 10°, specular component included).

[0229] In this L*a*b* system, L* represents the intensity of the color, a* indicates the green / red color axis and b* the blue / yellow color axis.

[0230] The color permanence of the deposits is evaluated by the AE color difference between Supplale® colored deposits before exposure and after exposure, i.e., immersion in two-phase water or artificial sebum, according to the protocol described above. The lower the AE value, the more resistant the color is to exposure.

[0231] The value of AE is calculated according to the following equation:

[0232] [Math.l] ae -

[0233] In this equation, L*a*b* represent the values ​​measured after staining of the Supplale® and after undergoing an attack, and Lo*ao*bo* represent the values ​​measured after staining of the Supplale® but before the attack. Results

[0234] The evaluation results are summarized in Table 3 below:

[0235] [Tables3] Properties Sebum resistance Deposit appearance AE values ​​Standard deviation Formula ((A) (B)) according to the invention 5.75 5.03 Average resistance to two-phase water, very good resistance to water and sebum Comparative formula ((AZ) F (B)) 23.70 10.44 Resistance to two-phase water, water and sebum significantly reduced compared to the formula according to the invention

[0236] It appears that the application of the formula ((A)+(B)) comprising a copolymer with acetoacetate functions according to the invention makes it possible to obtain a significantly improved sebum retention compared to the application of the comparative formula ((AZ)+(B)), comprising a copolymer with acetoacetate functions outside the invention.
