Description

Title of the invention: COMPOSITION FOR THE REVITALIZATION OF KERATINOUS FIBERS technical field

[0001] The present invention relates to a composition for revitalizing keratinous fibers, in particular human keratinous fibers such as hair. The present invention also relates to a cosmetic process for revitalizing keratinous materials. STATE OF THE ART

[0002] Under certain circumstances, such as sun exposure, keratinous fibers, such as the skin and scalp, are likely to sweat, resulting in sebum secretion.

[0003] Excessive sebum secretion on the scalp makes hair oily and damages its appearance, particularly its voluminous appearance.

[0004] Furthermore, the presence of sebum reduces the perceived freshness of the scalp. Oily scalp is the second major concern regarding hair and scalp problems, particularly among Chinese consumers.

[0005] There are many products developed to solve the problems caused by excess sebum.

[0006] For example, US5137715A discloses a hair shampoo-conditioner composition consisting substantially of: (a) about 1% to about 20% by weight of an anionic cleansing surfactant; (b) about 0.1% to about 2.5% by weight of a substantially non-crosslinked polymeric amidoamine; and (c) a suitable carrier comprising water; wherein the composition has a pH in the range of about 2.5 to less than 7.

[0007] However, many products on the market are not effective against excess sebum, so they cannot give hair a voluminous appearance.

[0008] We therefore wish to have an effective solution for excess sebum that can reduce the problems caused by thick sebum and give hair a voluminous appearance. Summary of the invention

[0009] An object of the present invention is therefore to develop compositions to revitalize keratinous fibers, which can reduce problems caused by thick sebum and give hair a voluminous appearance.

[0010] Thus, according to a first aspect, the present invention proposes a composition of re- revitalization of keratinous fibers including: a. at least one spherical particle of lipophilically modified silica; b. at least one superabsorbent polymer selected from starches grafted with an acrylic polymer; and c. at least one cross-linked hyaluronic acid polymer.

[0011] According to a second aspect, the present invention provides a cosmetic process for the revitalization of keratinous fibers comprising the application of the composition according to the present invention on said keratinous fibers.

[0012] The inventors have discovered that the composition according to the present invention can effectively combat sebum and make hair volumized.

[0013] Other subjects and features, aspects and advantages of the present invention will become even clearer upon reading the detailed description and examples that follow. DETAILED DESCRIPTION OF THE INVENTION

[0014] In this document, unless otherwise indicated, the limits of a range of values ​​are included in that range, in particular in the expressions "between... and..." and "from... to...".

[0015] In this document, the term "including" should be interpreted as encompassing all the features specifically mentioned as well as optional, additional, unspecified features.

[0016] As used herein, the use of the term "comprising" also discloses the embodiment in which no features other than the features specifically mentioned are present (i.e., "consisting of").

[0017] Unless otherwise defined, all technical and scientific terms used in this document have the meaning commonly accepted by a person skilled in the art of the present invention. Where the definition of a term in this description conflicts with the meaning commonly accepted by a person skilled in the art of the present invention, the definition described in this document shall prevail.

[0018] Unless otherwise specified, all numerical values ​​expressing a quantity of ingredients and other substances used in the description and claims shall be understood as modified by the term "approximately". Consequently, unless otherwise indicated, the numerical values ​​and parameters described in this document are approximate values ​​that may be modified according to the desired performance as required.

[0019] As used herein, the term "keratinous fibers" includes human keratinous fibers, in particular hair.

[0020] In this document, the expression "at least one" used in this description is equivalent to the expression "one or more".

[0021] According to the first aspect, the composition of the present invention comprises: a. at least one spherical particle of lipophilically modified silica; b. at least one superabsorbent polymer selected from starches grafted with an acrylic polymer; and c. at least one cross-linked hyaluronic acid polymer.

[0022] Spherical particles of lipophilically modified silica

[0023] The composition of the present invention comprises at least one spherical particle of lipophilically modified silica.

[0024] As used herein, a "spherical particle" means a particle in the shape of a sphere or at least approximately a sphere, and / or a particle having a side ratio of about 0.9 to 1.1, for example, about 0.95 to 1.05. For example, a person skilled in the art can determine whether a particle is spherical according to conventional knowledge. In particular, with regard to a given silica, it is within the ordinary competence of persons skilled in the art to distinguish the spherical shape from other plate, rod, powder, strip, irregular or similar shapes, and similar amorphous forms.

[0025] As used herein, "lipophilically modified" silica means silica that has undergone a lipophilic modification. According to the present invention, lipophilic modification refers to any organo-modification capable of imparting a hydrophobic or lipophilic treatment to silica. For example, silica may be treated with a siloxane compound, for example, T-hydroxydimethylsiloxane (or other silanes, such as silazane, etc.), whereby the silanol group on the surface of the silica and the silanol group of the siloxane compound are condensed.

[0026] In some embodiments, the lipophilically modified silica is chosen from silica treated with a siloxane compound, preferably chosen from silica silylate, silica dimethyl silylate and mixtures thereof.

[0027] Among others, useful examples of "lipophilically modified spherical silica particle" may be those available from TOKUYAMA CORPORATION under the name AIRLICA® TL-10.

[0028] According to the present invention, when incorporated into the composition, the lipophilically modified spherical silica particles can exhibit an oil absorption capacity of 500 mL / 100 g or more, 600 mL / 100 g or more, or even 700 mL / 100 g or more.

[0029] Advantageously, the lipophilically modified spherical silica particles are present in the composition according to the present invention in an amount ranging from 0.01% by weight to 5% by weight, preferably from 0.3% by weight to 2.5% by weight, plus preferably ranging from 0.5% by weight to 1.5% by weight, relative to the total weight of the composition. Superabsorbent polymer

[0030] The composition of the present invention comprises at least one superabsorbent polymer selected from starches grafted with an acrylic polymer.

[0031] The term "superabsorbent polymer" is intended to designate a polymer that, in its dry state, is capable of spontaneously absorbing at least 20 times its own weight of aqueous fluid, in particular water, and especially distilled water. Such superabsorbent polymers are described in "Absorbent Polymer Technology, Studies in Polymer Science 8" by L. Brannon-Pappas and R. Harland, published by Elsevier, 1990.

[0032] Advantageously, said superabsorbent polymer is selected from starches grafted with a homo- or copolymer acrylic, in particular starches grafted with sodium polyacrylate. Specifically, the acrylic polymer may be a homopolymer or a copolymer, in particular sodium polyacrylate.

[0033] These polymers have a high capacity to absorb and retain water and aqueous fluids. After absorption of the aqueous liquid, the polymer particles thus saturated with aqueous liquid remain insoluble in the aqueous liquid and thus retain their individualized particulate state.

[0034] The superabsorbent polymer can have a water absorption capacity ranging from 20 to 2000 times its own weight (i.e., from 20 g to 2000 g of water absorbed per gram of absorbent polymer), preferably from 30 to 1500 times, and even better from 50 to 1000 times. These water absorption characteristics are defined under standard conditions of temperature (25 °C) and pressure (760 mmHg, i.e., 100,000 Pa) and for distilled water. The water absorption capacity of a polymer can be determined by dispersing 0.5 g of polymer(s) in 150 g of a water solution, waiting 20 minutes, filtering the unabsorbed solution through a 150 µm filter for 20 minutes, and weighing the unabsorbed water.

[0035] The superabsorbent polymer used in the composition of the invention is in the form of particles. Preferably, the superabsorbent polymer has, in the dry or non-hydrated form, an average size less than or equal to 100 pm and preferably less than or equal to 50 pm, for example ranging from 1 to 100 pm, preferably from 5 to 50 pm and even better from 7 to 30 pm.

[0036] The average particle size corresponds to the mass average diameter (D50) measured by laser particle size analysis or other equivalent method known to those skilled in the art. These particles, once hydrated, swell while forming soft particles with an average size ranging from 10 pm to 2000 pm.

[0037] These polymers are known for their gelling properties and are generally used in a pre-swollen form in aqueous phase.

[0038] According to a particular embodiment of the invention, the superabsorbent polymer(s) used comprise 85% to 95% by weight of sodium polyacrylate and 5% to 15% by weight of starch. Preferably, they consist of 90% by weight of sodium polyacrylate and 10% by weight of starch.

[0039] According to a particular embodiment of the invention, the number-average molecular weight of the superabsorbent polymer(s) used is greater than 1000 daltons.

[0040] Examples include starches grafted with an acrylic polymer and in particular with sodium polyacrylate, such as those sold under the name Sanfresh ST-100MC by Sanyo Chemical Industries or Makimousse 25, Makimousse 12 or Ma-kimousse 7 by Daito Kasei (INCI name: sodium polyacrylate starch).

[0041] The superabsorbent polymers used in the present invention may or may not be crosslinked.

[0042] The superabsorbent polymers used in the present invention are preferably starches grafted with an acrylic homo- or copolymer, in particular sodium polyacrylate, which is in particulate form.

[0043] Preferably, the superabsorbent polymer is chosen from starches grafted with an acrylic homopolymer, preferably in the form of particles having an average size (or average diameter) less than or equal to 100 microns, more preferably in the form of particles, so that the hairs will not stick together and will have a volumized appearance.

[0044] With the presence of superabsorbent polymers, the composition of the present invention can offer a non-wet and quick-drying sensation.

[0045] On the other hand, since superabsorbent polymers have a good affinity with the skin, they ensure good fixation of the absorption beads, which can offer good oil control efficiency.

[0046] Advantageously, the superabsorbent polymer is present in the composition of the present invention in an amount ranging from 0.01% by weight to 5% by weight, preferably from 0.1% by weight to 3% by weight, more preferably from 0.1% by weight to 1% by weight, most preferably from 0.2% by weight to 0.8% by weight, relative to the total weight of the composition. Cross-linked hyaluronic acid polymers

[0047] The composition of the present invention comprises at least one cross-linked hyaluronic acid polymer.

[0048] Hyaluronic acid (HA) is a natural linear carbohydrate polysaccharide found in almost all living organisms. Its chemical structure consists of alternating repeating disaccharide motifs composed of D-glucuronic acid and N-acetylglucosamine linked together by alternating β-1,4 and β-1,3 glycosidic bonds. The number of repeats can reach 10,000 with a molecular weight of approximately 102 to 104kDa.

[0049] In general, the term "hyaluronic acid" encompasses all variants and combinations of variants of hyaluronic acid or hyaluronate, with different chain lengths and charge states, as well as with various chemical modifications. Specifically, the term also encompasses the various hyaluronate salts of hyaluronic acid with various counter-ions, such as sodium hyaluronate. Hyaluronic acid (HA) is a highly hydrophilic macromolecule that plays a key role in transporting water in the skin, maintaining hydration and stabilizing the structure of the epidermis and dermis. HA plays an important role in the structural characteristics of many tissues. Due to its unique spiral structure in aqueous solutions, HA exhibits highly effective hydrating properties, as it can retain up to 1000 times its weight in water.

[0050] Hyaluronic acid can be obtained from various animal and non-animal sources. Non-animal sources include yeast and bacteria.

[0051] In the context of the present invention, the crosslinked AH polymer comprises crosslinks between the AH chains, which creates a continuous network of AH molecules that are held together by covalent crosslinks, the physical entanglement of the AH chains and various interactions, such as electrostatic interactions, hydrogen bonds and van der Waals forces.

[0052] The crosslinking of hyaluronic acid (HA) can be achieved by modification with a chemical crosslinking agent. The chemical crosslinking agent can, for example, be selected from the group consisting of divinyl sulfone, multiepoxides, and diepoxides. In particular, hyaluronic acid is crosslinked by a bifunctional or polyfunctional crosslinking agent comprising two or more glycidyl ether functional groups. More specifically, the chemical crosslinking agent is selected from the group consisting of 1,4-butanediol diglycidyl ether (BDDE), 1,2-ethanediol diglycidyl ether (EDDE), diepoxyoctane, and a mixture thereof. Preferably, the chemical crosslinking agent is 1,4-butanediol diglycidyl ether (BDDE).

[0053] The crosslinked AH polymer can be a gel or a hydrogel. In other words, it can be considered as a water-insoluble, but substantially dilute, crosslinked system of hyaluronic acid molecules when subjected to a liquid, generally an aqueous liquid.

[0054] The gel consists mainly of liquid and may, for example, contain 90-99.9% water by weight, but it behaves like a solid due to a three-dimensional cross-linked HA network within the liquid. Because of its high liquid content, the gel is structurally flexible and similar to a natural tissue.

[0055] Such a cross-linked AH polymer gives the gel high strength and a long lifespan. life and high biocompatibility.

[0056] As mentioned, the crosslinking of AH to form the crosslinked AH polymer gel can, for example, be achieved by modification with a chemical crosslinking agent, e.g., BDDE (1,4-butandiol diglycidyl ether). The concentration of AH and the extent of crosslinking affect the mechanical properties, e.g., the elastic modulus G', and the stability properties of the gel. Crosslinked AH polymers are often characterized in terms of "degree of modification," "crosslinking ratio," and "degree of crosslinking" (Keene et al., Carbohydrate Polymers, 2013, 91, 410-418).

[0057] The degree of modification (MoD) of AH is generally between 0.1 and 15 mol%. The degree of modification (mol%) describes the amount of crosslinking agent(s) that is bound to AH, i.e., the molar amount of bound crosslinking agent(s) relative to the total molar amount of repeated AH disaccharide motifs. The degree of modification reflects the extent to which AH has been chemically modified by the crosslinking agent. In a preferred embodiment, the degree of modification of the crosslinked AH polymer with a chemical crosslinking agent is less than 15 mol%, preferably less than 1.9%, and more preferably between 0.1 and 1.9 mol%.

[0058] The crosslinked AH polymer can also be characterized by the crosslinking ratio (CrR). The crosslinking ratio (CrR) describes the proportion of total bound crosslinking agent (AH-X-AH and AH-X) that has bound two or more disaccharides (AH-X-AH only). The crosslinking ratio (CrR) of AH is generally between 0.01 and 0.50. In a preferred embodiment, the CrR is less than 0.30, preferably between 0.10 and 0.20, more preferably 0.10 or 0.20.

[0059] The AH crosslinking polymer can also be characterized by the degree of crosslinking (CrD) corresponding to the stoichiometric ratio between the crosslinking agent that is doubly linked and the disaccharide motifs of AH. In a preferred embodiment, the CrD is between 0.2 and 0.8, preferably between 0.2 and 0.5, more preferably between 0.2 and 0.4, and even more preferably 0.2.

[0060] A BDDE (1,4-butandiol diglycidyl ether) crosslinked HA gel can for example be prepared according to the process described in Examples 1 and 2 of published international patent application WO 97 / 04012.

[0061] According to the invention, the crosslinked AH polymer is preferably crosslinked by a chemical crosslinking agent, and the degree of modification of said AH polymer with said chemical crosslinking agent is less than 15% by mole, preferably less than 1.9% by mole.

[0062] More preferably, the degree of modification of said crosslinked hyaluronic acid polymer with said chemical crosslinking agent being in the range of 0.1% in mole to less than 1.9% by mole.

[0063] More preferably, the degree of modification with said chemical crosslinking agent is about 1.0% by mole.

[0064] In a particular embodiment, the AH crosslinked polymer is a sodium hyaluronate crosslinked polymer, which may be available under Hyacross™ from BLOOMAGE BIOTECHNOLOGY.

[0065] When the HA cross-linked polymer is applied to the hair root, it becomes less sticky. At the same time, it can modify the hydrophobicity of the hair root surface and provide a better anti-oil migration benefit.

[0066] Advantageously, the crosslinked hyaluronic acid polymer is present in the composition according to the present invention in an amount ranging from 0.01% by weight to 5% by weight, preferably from 0.01% by weight to 3% by weight, more preferably from 0.02% by weight to 2% by weight, most preferably from 0.03% by weight to 0.8% by weight, relative to the total weight of the composition.

[0067] It is preferable that the weight ratio of the superabsorbent polymer to the crosslinked hyaluronic acid polymer be 2 to 80, preferably 2 to 50, more preferably 2 to 30, so that a preferred balance of the composition's viscosity and the preferred sensation offered by the composition can be achieved, while a preferred user experience can be achieved with the composition. Aqueous phase

[0068] The composition of the present invention may further comprise at least one continuous aqueous phase.

[0069] Said aqueous phase is preferably present in an amount ranging from 50% by weight to 99% by weight, more preferably from 70% by weight to 99% by weight, relative to the total weight of the composition.

[0070] The aqueous phase comprises water.

[0071] Water is preferably present in the composition of the present invention in an amount ranging from 50% by weight to 99% by weight, preferably from 60% by weight to 99% by weight, relative to the total weight of the composition.

[0073] In some embodiments, the aqueous phase comprises one or more miscible organic solvents chosen from monoalcohols having 2 to 6 carbon atoms; polyols having 2 to 20 carbon atoms; glycol ethers having 3 to 16 carbon atoms, and mixtures thereof, more preferably chosen from ethanol, glycerin and mixtures thereof.
