Description

Title of the invention: cleansing and / or makeup-removing composition for keratinous materials technical field

[0001] The present invention relates to a cosmetic composition, in particular, a composition for cleansing and / or removing makeup from keratinous materials. The present invention also relates to a process for cleansing and / or removing makeup from keratinous materials using said composition. CONTEXT

[0002] Cleansing the skin or removing makeup is very important for skin care. It must be as effective as possible because oily residues, such as excess sebum, remnants of cosmetics used daily, and makeup products, especially waterproof products, accumulate in skin folds and can clog pores and lead to the appearance of pimples.

[0003] Several types of skin cleansing or makeup removal products are known, for example rinse-off anhydrous oils and gels, foaming creams and lotions.

[0004] The soap is well-received by the consumer because of its good lather, the feeling of freshness it provides, and the squeaking sensation it produces when all the oily sebum is removed. The squeaking sensation of the soap comes from the metallic soap (soap lather).

[0005] Metallic soap is insoluble in water and can settle on the skin, causing a grinding sensation because the water-insoluble compound can prevent fingers from moving easily on the face during washing. It removes all sebum and viscous cleansing surfactants from the skin.

[0006] However, the soap is somewhat hard due to the dryness resulting from the rapid evaporation of water. Reasons for the deterioration of the skin barrier include a high pH and the removal of excessive amounts of surface lipids from the skin, which have an occlusive effect on the skin to prevent water loss.

[0007] On the other hand, amino acid surfactants are increasingly popular due to their gentleness. They can produce foams at a lower pH than soap. They are less damaging to the skin barrier. However, cleansers based on amino acid surfactants do not produce as much metallic soap; therefore, consumers do not experience a squeaking sensation on their skin and consider amino acid surfactants ineffective for cleansing.

[0008] Moreover, compared to soap, it is difficult to stabilize the cleaner obtained with An amine surfactant alone. Thus, polymers and / or fillers, nonionic surfactants, and amphoteric surfactants are usually added to stabilize the cleaner. However, the presence of polymers and / or fillers, nonionic surfactants, and amphoteric surfactants also causes a non-squeaking sensation.

[0009] Thus, there remains a need for a soap-free cleanser that can cause a squeaking sensation and does not dry out the skin. Summary of the invention

[0010] The inventors have found that such a need can be satisfied by the present invention.

[0011] Thus, according to one aspect, the present invention provides a soap-free composition for cleansing and / or removing makeup from keratinous materials comprising:

[0012] a) at least one hydrophobic silica aerogel particle;

[0013] b) at least one cellulose particle; and

[0014] c) at least one surfactant.

[0015] When the composition according to the present invention is used to wash the skin, a very strong squeaking sensation can be quickly obtained.

[0016] In addition, the composition according to the present invention also makes it possible to obtain a good finish on the skin (i.e. a feeling of non-dry skin) after application.

[0017] The composition according to the present invention can be used to cleanse and / or remove makeup from keratinous materials, in particular, the skin, especially the face, lips and / or eyes.

[0018] According to another aspect, the present invention proposes a process for cleaning and / or removing makeup from keratinous materials, in particular from the skin, comprising applying the composition according to the present invention to the keratinous materials, in particular the skin, and rinsing off said composition after a period of massage.

[0021] In what follows and unless otherwise indicated, the limits of a range of values ​​are included in this range, in particular in the expressions "between ... and ..." and "ranging from ... to ...".

[0022] Furthermore, the expression "at least one" used in this description is equivalent to the expression "one or more".

[0023] Throughout this application, the term "comprising" shall be interpreted as encompassing all the specifically mentioned features as well as any optional, additional, and unspecified features. As used herein, the use of the term "comprising" also discloses the embodiment in which no features other than the specifically mentioned features are present (i.e., "consisting of").

[0024] Unless otherwise stated, all numerical values ​​expressing the quantity of ingredients and the like used in the description and claims shall be understood as modified by the term "approximately". Consequently, unless otherwise stated, the numerical values ​​and parameters described in this document are approximate values ​​that may be modified as needed for the intended purpose.

[0025] For the purposes of the present invention, the term "keratinous material" is intended to cover human skin. The face, lips, and eyes are considered more particularly according to the present invention.

[0026] All percentages in the present invention refer to a percentage by weight, unless otherwise indicated.

[0027] According to one aspect, the present invention relates to a soap-free composition for cleansing and / or removing makeup from keratinous materials comprising:

[0028] a) at least one hydrophobic silica aerogel particle;

[0029] b) at least one cellulose particle; and

[0030] c) at least one surfactant. Hydrophobic silica aerogel particles

[0031] The composition according to the present invention comprises at least one hydrophobic silica aerogel particle.

[0032] As used in this document, silica aerogels are porous materials obtained by replacing (by drying) the liquid component of a silica gel with air.

[0033] They are generally synthesized by a sol-gel process in a liquid medium, then dried, most often by extraction from a supercritical fluid, the most commonly used being supercritical CO2. This type of drying prevents shrinkage of the pores and the material. The sol-gel process and the various drying processes are described in detail in Brinker C J., and Scherer GW, Sol-Gel Science: New York: Academie Press, 1990.

[0034] Preferably, the hydrophobic silica aerogel particles that can be used in the present invention have a specific surface area per unit mass (SM) of 500 to 1500 m2 / g, preferably 600 to 1200 m2 / g and even better 600 to 800 m2 / g.

[0035] The specific surface area per unit mass can be determined by the BET (Brunauer-Emmett-Teller) nitrogen absorption process described in the Journal of the American Chemical Society, vol. 60, page 309, February 1938, and corresponding to the international standard ISO 5794 / 1 (Annex D). The BET specific surface area corresponds to the total specific surface area of ​​the particles considered.

[0036] Preferably, the hydrophobic silica aerogel particles usable in the present invention have a size expressed in average volume diameter (D[0.5]), ranging from 0.1 to 150 µm, preferably from 1 to 50 µm, in particular from 3 to 30 µm, more preferably from 5 to 20 µm, and even better from 5 to 15 µm.

[0037] The particle size of hydrophobic silica aerogel can be measured by static light scattering using a commercial particle size analyzer such as the Malvern MasterSizer 2000. The data are processed based on Mie scattering theory. This theory, which is accurate for isotropic particles, allows the determination of an "effective" particle diameter in the case of non-spherical particles. This theory is described in particular in the publication by Van de Hulst, H.C., "Light Scattering by Small Particles," Chapters 9 and 10, Wiley, New York, 1957.

[0038] According to an advantageous embodiment, the hydrophobic silica aerogel particles used in the present invention have a specific surface area per unit mass (SM) ranging from 600 to 800 m2 / g and a size expressed by the average volumetric diameter (D[0,5]) ranging from 5 to 20 qm and even better from 5 to 15 qm.

[0039] The hydrophobic silica aerogel particles used in the present invention may advantageously have a packed density p ranging from 0.04 g / cm3 to 0.10 g / cm3 and preferably from 0.05 g / cm3 to 0.08 g / cm3.

[0040] In the context of the present invention, this density, referred to as packed density, can be evaluated according to the following protocol:

[0041] 40 g of powder are poured into a measuring cylinder; the measuring cylinder is The measuring cylinder is then placed on a Stampf Volumeter Stay 2003 machine; it is then subjected to a series of 2500 compaction movements (this operation is repeated until the volume difference between two consecutive tests is less than 2%); the final volume Vf of compacted powder is then measured directly on the measuring cylinder. The compacted density is determined by the ratio m / Vf, in this case 40 / Vf (Vf being expressed in cm³ and m in g).

[0042] According to one embodiment, the hydrophobic silica aerogel particles that can be used in the present invention have a specific surface area per SV volume unit ranging from 5 to 60 m2 / cm3, preferably from 10 to 50 m2 / cm3 and even better from 15 to 40 m2 / cm3.

[0043] The specific surface area per unit volume is given by the relation: SV=SM. p ; where p is the packed density expressed in g / cm3 and SM is the specific surface area per unit mass expressed in m2 / g, as defined above.

[0044] Preferably, the hydrophobic silica aerogel particles according to the invention have an oil absorption capacity, measured at the wet point, ranging from 5 to 18 mL / g, preferably from 6 to 15 mL / g and even better from 8 to 12 mL / g.

[0045] The oil absorption capacity measured at the wet point, denoted Wp, corresponds to the amount of water that must be added to 100 g of particles to obtain a homogeneous paste.

[0046] It is measured according to the wet point method or the method for determining the oil absorption of a powder described in standard NF T 30-022. It corresponds to the quantity of oil adsorbed on the available surface of the powder and / or absorbed by the powder by the wet point measurement, described below:

[0047] A quantity m = 2 g of powder is placed on a glass plate, and then the oil (isononyl isononanoate) is added drop by drop. After adding 4 to 5 drops of oil to the powder, the mixture is stirred with a spatula, and the addition of oil is continued until a conglomerate of oil and powder has formed. At this stage, the oil is added one drop at a time, and the mixture is then triturated with the spatula. The addition of oil is stopped when a firm, smooth paste is obtained. This paste must be able to be spread on the glass plate without cracking or forming lumps. The volume Vs (expressed in mL) of oil used is then recorded.

[0048] Oil absorption corresponds to the ratio Vs / m.

[0049] By "hydrophobic silica" is meant any silica whose surface is treated with silylation agents, for example halogenated silanes such as alkylchlorosilanes, alkylsiloxanes, in particular dimethylsiloxanes or hexamethyldisiloxane, or silazanes, so as to functionalize the OH groups with Si-Rn silyl groups, for example trimethylsilyl groups.

[0056] As used in this document, the term "cellulose" refers to any polysaccharide compound having in its structure sequences of glucose residues linked together by β-1,4 bonds, and in addition to unsubstituted celluloses, a derivative thereof may be used. For example, cellulose ethers, cellulose esters, and cellulose ester ethers (such as carboxymethylcellulose, hydroxyethylcellulose, and hydroxypropylmethylcellulose) may be used.

[0057] Preferably, the cellulose is microcrystalline cellulose.

[0058] Microcrystalline cellulose is a purified and partially depolymerized cellulose obtained from fibrous plant material in the form of a paste.

[0059] Cellulose preferably has an average particle size of 10 µm to 150 µm, preferably 30 µm to 100 µm, and more preferably 50 µm to 80 µm. The average particle size means the average particle size by volume.

[0073] The carboxylate salts of these amino acids can be formed by conventional means such as the neutralization of the respective amino acid with a base. The amino group located on the α-carbon or the [3]-carbon of the neutralized amino acid is acylated with a fatty acid halide (acyl halide) in the presence of a base by the well-known Schotten-Baumann reaction, yielding the amide, thus forming the desired surfactant reaction product, i.e., the amino acid surfactant. Suitable acyl halides for the acylation of the amino acid carboxylate salt include acyl chlorides, bromides, fluorides, and iodides.
