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 hydrophilic crosslinking agent technical field

[0001] The present invention relates more particularly to the cosmetic field of keratinous materials, and especially to that of makeup for the skin and / or eyelashes and / or eyebrows. It aims to provide a method for applying makeup to keratinous materials comprising at least the application to said keratinous materials of at least two distinct compositions (A) and (B). The invention also relates to a makeup kit for keratinous materials comprising at least two compositions (A) and (B) packaged separately. Previous technique

[0002] 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.

[0003] Thus, in the field of skin makeup, it is particularly expected that the deposit formed will not transfer upon contact with fingers or clothing.

[0004] It must also exhibit good resistance to contact with water, particularly rain or during showering, as well as perspiration and oils, such as sebum, especially when in contact with water. Furthermore, this coating must be comfortable and even glossy.

[0005] 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.

[0006] 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 shampoo. In fact, generally speaking, these polymers do not allow for deposits on keratin materials that meet all the aforementioned requirements, namely very good water resistance, particularly to hair shampoos, which allows for the adjustment of qualities of shine or invisibility and which, in the case of hair use, provide a very satisfactory hold of the hairstyle.

[0007] 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 resistance to water and shampoos.

[0008] These documents do not allow for obtaining non-sticky deposits, which transfer little, are comfortable, and are persistent. Description of the invention

[0009] 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.

[0010] There also remains a need for compositions that are resistant to various mechanical and chemical aggressions, for example water, makeup-removing compositions such as two-phase waters, or sebum.

[0011] There also remains a need for compositions that provide qualities of brilliance and color retention.

[0012] The present invention is specifically aimed at meeting all or part of these needs. Summary of the invention

[0013] 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):

[0014] [Chem.l] (I)

[0015] 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 selected 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 / or silicone; v) at least one monoalcohol comprising 2 to 4 carbon atoms; and - said composition (B) comprising at least: vii) a crosslinking agent selected from hydrophilic (poly)amine compounds selected from a) aminoalkoxysilanes; b) polyamine compounds comprising 2 to 20 carbon atoms, linear or branched, acyclic or cyclic, saturated or unsaturated, conjugated or non-conjugated, aromatic or non-aromatic, optionally substituted by at least one hydroxyl (-OH) and / or carboxylic (-C(=O)OH) radical and / or optionally interrupted by one or more heteroatoms or groups selected from -S-, -SS-, -N(R”)- preferably -N(R”)-, with R” representing a hydrogen atom or a (Ci-C4)alkyl group, preferably a hydrogen atom; c) chitosans;d) compounds of formula (III): ALK[(O-ALK')m-NH2]2 (III), e) triamine polyethers, in particular of formula (IV): ALK”'[(O-ALK')m-NH2]3, f) α, co-diamine polybutadienes, g) hyperbranched polymers comprising at least one amino group and dendrimers bearing at least one amino group, such as PAMAM polyamidoamine dendrimers with an ethylenediamine core and a terminal amine function, as well as mixtures thereof; viii) an organic or mineral acid; and ix) water; - said composition (A) and / or said composition (B) comprising vi) at least one particulate colouring material.

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 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.

[0205] Any type of applicator can be used for the deposition of the first and / or second composition.

[0206] The respective applicators of the first and second composition may be identical or distinct.

[0207] 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.

[0208] According to another variant, the makeup kit according to the present invention comprises one or more means of applying the first and second compositions.

[0209] 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.

[0210] 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.

[0211] The threaded rod may be made of plastic or metal or any other suitable material.

[0212] The pen with a notched wheel is more particularly described in US application 5851019 or FR 2588733.

[0213] 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.

[0214] 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.

[0215] According to a particularly advantageous embodiment, this packaging article is provided with two separate applicators.

[0216] The second method consists of pre-mixing the two compositions, just before applying the resulting composition to the keratinous materials.

[0217] 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 prior to application, such as a container and a stirrer.

[0218] 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.

[0219] 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.

[0220] 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.

[0221] Alternatively, the containers are made of non-thermoplastic material, in particular glass or metal (or alloy).

[0222] 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, to be wiped. Such a wringer is described, for example, in French patent FR 2792618.

[0223] Throughout the description, including the claims, the expressions "between ... and ..." and "ranging from ... to ..." shall be understood to include bounds, unless otherwise specified.

[0224] The invention is illustrated in more detail in the following examples. Quantities are indicated as a percentage by weight. Examples

[0225] Compound 1: Preparation of the copolymer Isobutyl Acrylate / Tertiobutyl Acrylate / Acetoxyethyl Methacrylate (25 / 65 / 10)

[0226] In a 1 L controlled reactor, 62.5 g of isobutyl acrylate, 162.5 g of tert-butyl acrylate,

[0227] 25 g of acetoacetoxyethyl methacrylate, 2.5 g of the radical initiator Trigonox T21S and 360 g of a 50 / 50 isododecane / ethyl acetate solvent are introduced. The mixture is degassed with argon and then heated to 90 °C with stirring. The reaction mixture is maintained at 90 °C for 7 hours, and then stripping is performed with 300 mL of isododecane to remove residual monomers.

[0228] As a result of the reaction, a copolymer of isobutyl acrylate / tert-butyl acrylate / acetoacetoxyethyl methacrylate is obtained in solution in isododecane.

[0229] Compound 2: Preparation of the copolymer Isobornyl acrylate / Acetoacetoxyethyl methacrylate (90 / 10)

[0230] In a 1 L controlled reactor, 135 g of isobornyl acrylate, 30 g of acetoacetoxyethyl methacrylate, 100 g of an isododecane / ethyl acetate solvent (70 / 30), and 100 g of isododecane alone are introduced.

[0231] The medium is degassed with argon and then heated to 90 °C under stirring (100 revolutions / minute).

[0232] 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.

[0233] 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.

[0234] As a result of the reaction, an isobutyl acrylate / acetoacetoxyethyl methacrylate copolymer is obtained in solution in isododecane. Preparation of compositions A, AZ, Bl, B2 and B2'

[0235] Compositions A, AZ, Bl, B2 and B2' 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.

[0236] [Tables 1] Ingredients Composition (A) according to the invention Comparative composition (AZ) Compound 1: Isobutyl acrylate / tert-butyl acrylate / acetoacetoxyethyl methacrylate (25 / 65 / 10) copolymer in isododecane 42.7 (27.52 active material) - Compound 2: Isobornyl acrylate / acetoacetoxyethyl methacrylate (90 / 10) copolymer in isododecane - 42.7 (27.52 active material) Butyl acetate 19 19 Hexyene glycol 13.72 13.72 Isododecane qs 100 qs 100 Black iron oxide 10 10 Ethanol 10.16 10.16

[0238] 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

[0239] Each of the compositions (A) according to the invention and (AZ) comparative were mixed with each of the compositions (B 1), (B2), (B 1 ') and (B2') in a mass ratio of 1:1, using a SpeedMixer® Hauschild DAC 150.1 FVZ) (10 grams, 1 cycle, 2 minutes 30 seconds, 2500 rpm). Application

[0240] Each formula ((A) + (Bl)), ((A) + (Bl')), ((A) + (B2)), ((A) + (B2')), ((AZ) + (Bl)), or ((AZ) + (B2)) was applied with a spatula to a supplale® support (SOUDOTIQUE reference RLXSUPNOIR, format: 30000 X 1200 MM X 0.7 MM) measuring 2 cm x 5 cm, at a rate of 0.02 g / cm2.

[0241] Drying takes place at room temperature for 24 hours. Water resistance

[0242] Once dry, the Supplale® thus treated are immersed in water for 3 minutes.

[0243] 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.

[0244] To measure color fastness, a color difference (delta E) is measured between the initial deposit and the deposit after immersion in water. Persistence Protocol

[0245] 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).

[0246] 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.

[0247] The color permanence of the deposits is evaluated by the color difference AE between the Supplale® colored before and after exposure to water, i.e., immersion in water according to the protocol described above. The lower the AE value, the more persistent the color.

[0248] The value of AE is calculated according to the following equation:

[0249] [Math.l] AE =

[0250] In this equation, L*a*b* represent the values ​​measured after staining the Supplale® and after having undergone an aggression, and Lo*ao*bo* represent the values ​​measured after staining the Supplale® but before aggression. Results

[0251] Evaluation of the presence of a copolymer with acetoacetate function according to the invention

[0252] The results of the water resistance assessments are summarized in Table 3 below:

[0253] [Tables3] Mixtures AE Standard deviation Formula ((A) + (B1)) according to invention 1.86 1.58 Comparative formula ((AZ) * (B1)) 25.13 17.06 Formula ((A) + (B2)) according to the invention 2.49 1.15 Comparative formula ((AZ) * (B2)) 31.25 6.17

[0254] It appears that the application of the formulas ((A) + (B 1)), ((A) + (B2)), comprising a copolymer with acetoacetate function according to the invention makes it possible in particular to obtain a significantly improved water resistance of the deposit compared with the application of the respective comparative formulas ((AZ) + (Bl)), ((AZ) + (B2)), comprising a copolymer with acetoacetate function outside the invention.

[0255] Evaluation of the presence of a mineral or organic acid

[0256] The results of the evaluations of the compositions according to the invention are summarized in Table 4 below:
