Description

Title of the invention: Makeup composition of keratinous materials technical field

[0001] The present invention relates to the field of cosmetics, and in particular to the field of makeup compositions of keratinous materials. CONTEXT

[0002] Many consumers wish to use cosmetic and skincare compositions that enhance the appearance of keratinous materials, particularly the skin, specifically its optical cosmetic effect, such as brightening, coverage, and radiance. Cosmetic compositions capable of providing the aforementioned optical effects to the skin are known, for example, as foundation products containing emulsion-type colorants and oils, particularly water-in-oil emulsions. Furthermore, this cosmetic effect is desired to be long-lasting, due to the routine use of such products (all-day application). However, these foundation products are not always satisfactory.For example, a film-forming agent can generally offer lasting benefits to a makeup product, such as foundation, which will, however, normally provide a feeling of tight skin.

[0003] In addition to the cosmetic effect mentioned above, consumers have increasing demands regarding the sensory properties of the skin. Hydration is now one of the most demanding needs.

[0004] It is known that cosmetic products containing a large amount of aqueous phase can provide a feeling of hydration to the skin. Efforts have been made to formulate foundation products with a large amount of aqueous phase, or in particular oil-in-water emulsions, of the oil dispersion type, to meet this need. However, obtaining an aqueous texture is usually incompatible with the desired cosmetic properties as described above, and furthermore, incompatible with the stability of foundation-type cosmetic products.

[0005] Consequently, the formulation of a makeup composition of keratinous materials with a good expected skin feel as well as hydration remains a difficulty that the person skilled in the art faces. Summary of the invention

[0006] The present invention aims to solve one or more of the problems mentioned above.

[0007] Therefore, in one aspect, an object of the invention is to formulate compositions, in particular makeup foundations, which are capable, upon application, of providing a good skin sensation and also lasting hydration on keratinous materials, in particular the skin.

[0008] In another aspect, an object of the invention is to formulate compositions, in particular makeup foundations, that provide a good moisturizing effect to keratinous materials, especially the skin. In particular, the moisturizing effect is long-lasting without compromising the feel.

[0009] Through a thorough study, the inventors discovered that one or more of the aforementioned objectives can be met by proposing a composition for treating keratinous materials, particularly skin, comprising: A. at least one silicone acrylate copolymer; and B. at least one polyoxybutylene polyoxyethylene polyoxypropylene glycerol.

[0010] Another subject of the present invention is the use of the composition of the present invention in the preparation of a makeup / care product for keratinous materials, for example skin. METHODS OF IMPLEMENTING THE INVENTION

[0011] Throughout the description, including the claims, the term "comprising a" shall, unless otherwise stated, be understood as synonymous with "comprising at least one". Furthermore, the expression "at least one" used in this description is equivalent to the expression "one or more".

[0012] Throughout the description, including the claims, an embodiment defined with "comprising" or similar should be understood as encompassing a preferred embodiment defined with "consisting essentially of" and a preferred embodiment defined with "consisting of".

[0013] By "keratinous materials" we mean human keratinous materials such as skin, lips and nails, in particular skin and lips, more preferably skin, in particular facial skin.

[0014] In the application, unless specifically stated otherwise, contents, parts and percentages are expressed on a weight basis.

[0015] The present invention relates to a makeup composition of keratinous materials, comprising the following components: A. at least one silicone acrylate copolymer; and A. at least one polyoxybutylene polyoxyethylene polyoxypropylene glycerol. Component A), silicone acrylate copolymers

[0016] The composition of the present invention may contain at least one silicone acrylate copolymer as component A).

[0017] Silicone acrylate copolymers can function as film-forming agents within the meaning of the present invention. They are available as silicone acrylate copolymers with a (meth)acrylate backbone grafted with a silicone chain, or as a silicone backbone grafted with a (meth)acrylate, or as a silicone acrylate dendrimer.

[0018] Silicone acrylate dendrimers, such as those described and claimed in US Patent No. 6,280,748, may be preferred for use in the composition of the present invention. The silicone acrylate dendrimer is composed of a vinyl polymer having a carbosiloxane dendrimer structure in its side chain. It is characterized by a vinyl-type polymer that has a carbosiloxane dendrimer structure in its side chain. The term "carbosiloxane dendrimer structure" refers to a structure with high molecular weight groups branched with high regularity in a radial direction from a single nucleus.

[0019] The vinyl polymer skeleton is formed from a vinyl-type monomer containing a radically polymerizable vinyl group. In its broadest definition, there are no particular limitations as to the type of such a monomer. A particularly preferred vinyl polymer is a (meth)acrylate.

[0020] Preferably, the silicone acrylate copolymers are selected from acrylate / dimethicone copolymers, an acrylate / stearyl acrylate / dimethicone acrylate copolymer, an acrylate / behenyl acrylate / dimethicone acrylate copolymer, an acrylate / polytrimethylsiloxymethacrylate copolymer, poly(dimethylsiloxane)-γ-poly(isobutyl methacrylate), and mixtures thereof. More preferably, the silicone polymer is an acrylate / trimethyl polysiloxymethacrylate copolymer.

[0021] Non-limiting examples of these copolymers are acrylate / dimethicone copolymers such as those commercially available from Shin-Etsu, for example, products sold under the trade names KP-545 (cyclopentasiloxane (and) acrylate / dimethicone copolymer), KP-543 (butyl acetate (and) acrylate / dimethicone copolymer), KP-549 (methyl trimethicone (and) acrylate / dimethicone copolymer), KP-550 (INCI name: isododecane (and) acrylate / dimethicone copolymer), KP-561 (acrylate / stearyl acrylate / dimethicone acrylates copolymer), KP-562 (acrylate / behenyl acrylate / dimethicone acrylates copolymer), and mixtures thereof.Other examples include acrylate / dimethicone copolymers sold by Dow Corning under the trade names FA 4001 CM SILICONE ACRYLATE (cyclopentasiloxane (and) trimethyl acrylate / polysiloxymethacrylate copolymer), FA 4002 ID SILICONE ACRYLATE (isodecane (and) acrylate / polysiloxymethacrylate copolymer). trimethyl), and FA 4004 ID SILICONE ACRYLATE (isodecane (and) trimethyl acrylates / polysiloxymethacrylate copolymer), and mixtures thereof.

[0022] The number average molecular weight of the silicone acrylate dendrimers intended for use in the composition of the present invention may preferably range from about 3,000 to about 2,000,000, or from about 5,000 to about 800,000.

[0023] Component A), silicone acrylate copolymer may be present in the composition in an amount from 0.1% to 5% by weight, preferably from 0.2% to 3% by weight, and more preferably from 0.5% to 1.5% by weight, relative to the total weight of the composition.

[0024] Component B). Polyoxybutylene, polyoxyethylene, polyoxypropylene, glycerol

[0025] The composition of the present invention may contain at least one polyoxybutylene polyoxyethylene polyoxypropylene glycerol as component B).

[0026] Polyoxybutylene, polyoxyethylene, polyoxypropylene, and glycerol can be represented by the formula (I) below:

[0027] Gly-{O(PO)s(EO)t-(BO)uH}3 (I)

[0028] in which

[0029] Gly designates a residue obtained by elimination of hydroxyl groups from glycerin;

[0030] PO designates an oxypropylene group;

[0031] EO designates an oxyethylene group;

[0032] s and t denote the average number of moles of addition of PO and EO, respectively, and have a value ranging from 1 to 50;

[0033] the weight ratio PO to EO (PO / EO) goes from 1 / 5 to 5 / 1;

[0034] BO designates an oxyalkylene group comprising 4 carbon atoms; and

[0035] u denotes the average number of moles of BO addition, and ranges from 0.5 to 5.

[0036] Advantageously, in formula (I):

[0037] s goes from 2 to 15, preferably from 3 to 7;

[0038] t goes from 3 to 20, preferably from 6 to 10;

[0039] u goes from 1 to 5, preferably from 2 to 4.

[0040] The polyoxybutylene polyoxyethylene polyoxypropylene glycerol represented by formula (I) can be obtained by adding propylene oxide and ethylene oxide to glycerin, in the ratio of 3 to 150 molar equivalents of each of the propylene oxide and ethylene oxide with respect to glycerin, and then adding the alkylene oxide having 4 carbon atoms in the ratio of 1.5 to 15 molar equivalents thereof with respect to glycerin.

[0041] In the case of the addition of the aforementioned alkylene oxides to glycerin, the addition reactions are carried out with an alkali catalyst, a phase-transfer catalyst, a Lewis acid catalyst, or the like. In general, an alkali catalyst such as potassium hydroxide is preferably used.

[0042] Among the polyoxybutylene polyoxyethylene polyoxypropylene glycerol represented by formula (I), the most preferable are those obtained by adding 6 to 10 mol of ethylene oxide and 3 to 7 mol of propylene oxide to glycerin, and then adding 2 to 4 mol of butylene oxide.

[0043] Among the polyoxybutylene polyoxyethylene polyoxypropylene glycerol represented by formula (I), PEG / PPG / polybutylene glycol-8 / 5 / 3 glycerin is preferred, which is obtained by adding 8 mol of ethylene oxide and 5 mol of propylene oxide to the glycerin, and then adding 3 mol of butylene oxide.

[0044] PEG / PPG / polybutylene glycol-8 / 5 / 3 glycerin is commercially available under the trade name WILBRIDE S-753D from NOF Corporation.

[0045] Component B), polyoxybutylene polyoxyethylene polyoxypropylene glycerol, may be present in the composition in an amount from 0.1% to 10% by weight, preferably from 0.2% to 5% by weight, and more preferably from 0.5% to 2% by weight, relative to the total weight of the composition.

[0046] The polyoxybutylene, polyoxyethylene, polyoxypropylene, and glycerol of component B) can serve as a humectant according to the invention. Without limiting itself to any known theory, it is thought that the simultaneous use of specific components A) and B) can promote the formation of a more flexible and less tight film, so as to provide instant and lasting hydration while maintaining a pleasant feel.

[0047] Furthermore, without being limited to any known theory, it is estimated that an appropriate ratio between component A) and component B) can be particularly beneficial for desired hydration, especially a better balance between desired hydration and sensory effects. Specifically, it is highly preferable to use components A) and B) in similar quantities by weight. Therefore, the weight ratio of component A) to component B) is preferably 2:5-5:2, more preferably 1:2-2:1. Oils)

[0048] The composition of the present invention may be in the form of an emulsion and may therefore comprise at least one oil.

[0049] The term "oil" refers to any fat in liquid form at room temperature (20-25°C) and atmospheric pressure.

[0050] These oils may be of animal, vegetable, mineral or synthetic origin.

[0051] Oils can be volatile or non-volatile.

[0052] The term “volatile oil” refers to any non-aqueous medium capable of evaporating from the skin or lips in less than one hour at room temperature (20–25°C) and atmospheric pressure (760 mmHg). Volatile oil is a cosmetic oil that is volatile and liquid at room temperature. More specifically, a volatile oil has an evaporation rate of 0.01 to 200 mg / cm² / min.

[0053] The term "non-volatile oil" is intended to designate an oil that remains on the skin or keratinous fiber at room temperature and atmospheric pressure. More specifically, a non-volatile oil has an evaporation rate strictly less than 0.01 mg / cm² / min.

[0054] To measure this evaporation rate, 15 g of the oil or a mixture of oils under test are introduced into a 7 cm diameter crystallizing dish placed on a scale in a large 0.3 m³ chamber at a controlled temperature of 25°C and a controlled relative humidity of 50%. The liquid evaporates freely, without agitation, with ventilation provided by a fan (PAPST-MOTOREN, reference 8550 N, rotating at 2700 rpm) positioned vertically above the crystallizing dish containing the solvent, with the blades directed towards the crystallizing dish and at a distance of 20 cm from the base of the dish. The mass of oil remaining in the crystallizing dish is measured at regular intervals. The evaporation rates are expressed in mg of oil evaporated per unit area (cm²) per unit time (minute).

[0055] According to the present invention, the term “silicone oil” refers to an oil comprising at least one silicon atom, and in particular at least on the Si-O group.

[0056] The term "hydrocarbon oil" refers to an oil containing mainly hydrogen and carbon atoms.

[0057] The oils may optionally include atoms of oxygen, nitrogen, sulfur and / or phosphorus, for example in the form of hydroxyl or acid radicals.

[0063] and mixtures thereof.

[0064] Preferably, the oil is chosen from non-volatile linear or cyclic polydimethylsiloxanes, phenyl silicones, more preferably from cyclohexasiloxane, phenyl trimethicone, or a mixture of these.

[0065] The oil may be present in the composition of the invention in an amount ranging from 0.1% to 15% by weight, preferably from 0.2% to 10% by weight, or preferably from 0.5% to 5% by weight, relative to the weight of the composition. Surfactant
