Description

Title of the invention: HAIR REVITALIZING COMPOSITION technical field

[0001] The present invention relates to a hair revitalizing composition. The present invention also relates to a cosmetic hair revitalizing process. STATE OF THE ART

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

[0003] Excessive sebum secretion on the scalp makes hair oily and alters its appearance, such as its voluminous appearance.

[0004] Furthermore, the presence of sebum reduces the perceived freshness of the scalp. An oily scalp is the second biggest 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 polymer 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] It is therefore desirable to have an effective solution against excess sebum, capable of reducing the problems caused by abundant sebum and giving hair a voluminous appearance. Summary of the invention

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

[0010] Thus, according to a first aspect, the present invention proposes a hair revitalizing composition comprising: 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 hair conditioning agent.

[0011] According to a second aspect, the present invention proposes a cosmetic process for revitalizing hair comprising the application of the composition according to the present invention to the hair.

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

[0015] 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 hair conditioning agent.

[0016] Spherical particles of lipophilically modified silica

[0017] The composition of the present invention comprises at least one spherical particle of lipophilically modified silica.

[0018] As used herein, a "spherical particle" means a particle in the shape of a sphere or at least an approximate sphere, and / or a particle having a height-to-width 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 shapes such as plate, rod, powder, strip, irregular or similar shapes, and from similar amorphous forms.

[0019] As used herein, "lipophilically modified" silica means silica that has undergone lipophilic modification. According to the present invention, lipophilic modification means 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, 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 compounds are condensed.

[0020] 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.

[0021] Among others, useful examples of "lipophilically modified spherical silica particle" may be that available from TOKUYAMA CORPORATION under the name AIRLICA® TL-10.

[0022] 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.

[0023] 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 ranging from 0.3% by weight to 2.5% by weight, more preferably ranging from 0.5% by weight to 1.5% by weight, relative to the total weight of the composition. Superabsorbent polymer

[0024] The composition of the present invention comprises at least one superabsorbent polymer selected from starches grafted with an acrylic polymer.

[0025] The term "superabsorbent polymer" is intended to designate a polymer capable, in its dry form, 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-Peppas and R. Harland, published by Elsevier, 1990.

[0026] 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.

[0027] These polymers have a high capacity for absorbing and retaining 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.

[0028] 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 value of 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 for 20 minutes, filtering the unabsorbed solution through a 150 µm filter for 20 minutes and weighing the unabsorbed water.

[0029] The superabsorbent polymer used in the composition of the invention is in the form of particles. Preferably, the superabsorbent polymer has, in 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.

[0030] 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.

[0031] Such polymers are known for their gelling properties and are generally used in pre-swollen form in aqueous phase.

[0032] According to a particular embodiment of the invention, the super-absorbent polymer(s) used comprises 85% to 95% by weight of sodium polyacrylate and 5% to 15% by weight of starch. Preferably, it / they is / are composed of 90% by weight of sodium polyacrylate and 10% by weight of starch.

[0033] According to a particular embodiment of the invention, the number average molecular weight of the superabsorbent polymer(s) used is greater than 1000 daltons.

[0034] In particular, we can mention 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 Makhnousse 25, Makhnousse 12 or Ma-kimousse 7 by Daito Kasei (INCI name: Sodium polyacrylate starch).

[0035] The superabsorbent polymers used in the present invention may be crosslinked or non-crosslinked.

[0036] 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.

[0037] 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.

[0038] With the presence of superabsorbent polymers, the composition of the present invention can give a non-wet and quick-drying sensation.

[0039] On the other hand, since superabsorbent polymers have a good affinity with the skin, this results in good fixation of the absorption beads, which can give good sebum control efficiency.

[0040] Advantageously, the superabsorbent 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 ranging from 0.1% by weight to 3% by weight, more preferably ranging from 0.1% by weight to 1% by weight, most preferably ranging from 0.2% by weight to 0.8% by weight, relative to the total weight of the composition.
