Description

Technical Field

[0001] This invention relates to compositions for conditioning hair. It also relates to cosmetic methods for conditioning hair. Background Technology

[0002] In certain situations, such as under sunlight exposure, keratinous materials, such as skin and scalp, may sweat, leading to sebum production.

[0003] Excessive sebum production on the scalp makes hair greasy and damages its appearance, such as its volumized look.

[0004] In addition, the presence of sebum reduces the perceived freshness of the scalp. Oily scalp is the second most common hair and scalp problem, especially among Chinese consumers.

[0005] Many products have been developed to address problems caused by excess sebum.

[0006] For example, US5137715A discloses a hair shampoo-conditioner composition comprising essentially the following: (a) about 1% to about 20% by weight of an anionic cleaning surfactant; (b) about 0.1% to about 2.5% by weight of a substantially uncrosslinked polymeric amide amine; and (c) a suitable carrier containing 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 ineffective against excess sebum, making them unable to give hair a fuller look.

[0008] Therefore, it is desirable to have a solution that is effective against excess sebum, which can reduce the problems caused by thick sebum and give hair a fuller appearance. Summary of the Invention

[0009] Therefore, one object of the present invention is to develop compositions for conditioning hair that reduce problems caused by thick sebum and give hair a fuller appearance.

[0010] Therefore, according to a first aspect, the present invention provides a composition for conditioning hair, comprising: a) At least one spherical particle of lipophilic modified silica; b) at least one superabsorbent polymer selected from starch grafted with an acrylic polymer; and c) At least one hair conditioner.

[0011] According to a second aspect, the present invention provides a cosmetic method for conditioning hair, comprising applying a composition according to the invention to hair.

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

[0013] Other subjects, features, aspects, and advantages of the invention will become even clearer after reading the following detailed description and examples. Invention Details As used herein, unless otherwise stated, the limits of a numerical range are included within that range, particularly in expressions “between … and …” and “… to …”.

[0015] As used herein, the term “includes / comprising” should be interpreted as covering all specifically mentioned features as well as optional, additional, or unspecified features.

[0016] As used herein, the use of the term “comprising / including” also discloses an implementation in which no features other than those specifically mentioned (i.e., “composed of”) are present.

[0017] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. Where a definition of a term in this specification conflicts with the meaning commonly understood by one of ordinary skill in the art to which this invention pertains, the definition set forth herein shall prevail.

[0018] Unless otherwise stated, all numerical values ​​representing quantities of ingredients, etc., used in the specification and claims should be understood to be modified by the term "about". Therefore, unless indicated otherwise, the numerical values ​​and parameters described herein are approximate values ​​that can be varied as needed to obtain the desired performance.

[0019] As used herein, the expression "at least one" is equivalent to the expression "one or more".

[0020] According to a first aspect, the composition of the present invention comprises: a) At least one spherical particle of lipophilic modified silica; b) at least one superabsorbent polymer selected from starch grafted with an acrylic polymer; and c) At least one hair conditioner.

[0021] Spherical particles of lipophilic modified silica The compositions of the present invention comprise at least one spherical particle of lipophilic modified silica.

[0022] As used herein, "spherical particles" means particles that are spherical or at least approximately spherical in shape, and / or particles having an aspect ratio of about 0.9 to 1.1, for example, about 0.95 to 1.05. For example, those skilled in the art can determine whether a particle is spherical based on conventional knowledge. In particular, with respect to a given silica, distinguishing a spherical shape from the shapes of other plates, rods, powders, strips, irregular shapes, etc., and from amorphous analogues, is within the conventional skill of those skilled in the art.

[0023] As used herein, "lipophilic modified" silica refers to silica that has undergone lipophilic modification. According to the invention, lipophilic modification refers to any organic modification capable of hydrophobic or lipophilic treatment of silica. For example, silica can be treated with siloxane compounds, such as hydroxydimethylsiloxane (or other silanes, such as silazanes), whereby the silanol groups on the silica surface undergo condensation with the silanol groups of the siloxane compound.

[0024] In some embodiments, the lipophilic modified silica is selected from silica treated with siloxane compounds, preferably from silyl alkyl silica, dimethyl silyl silica, and mixtures thereof.

[0025] In particular, a useful example of "spherical particles" of "lipophilic modified" silica can be found in the AIRLICA product of TOKUYA MACORPORATION. ® The kind of name obtained from TL-10.

[0026] According to the present invention, when incorporated into a composition, spherical particles of lipophilic modified silica can exhibit an oil absorption capacity of 500 ml / 100 g or higher, 600 ml / 100 g or higher, or even 700 ml / 100 g or higher.

[0027] Advantageously, spherical particles of lipophilic modified silica are present in the composition in an amount ranging from 0.01% to 5% by weight, preferably from 0.3% to 2.5% by weight, and more preferably from 0.5% to 1.5% by weight, relative to the total weight of the composition according to the invention.

[0028] Superabsorbent polymers The compositions of the present invention comprise at least one superabsorbent polymer selected from starch grafted with an acrylic polymer.

[0029] The term "superabsorbent polymer" is intended to refer to polymers capable of spontaneously absorbing at least 20 times their own weight in aqueous fluids, particularly water, and especially distilled water, in their dry form. Such superabsorbent polymers are described in L. Brannon-Peppas and R. Harland's book "Absorbent polymer technology, Studies in polymer science 8" (published by Elsevier, 1990).

[0030] Advantageously, the superabsorbent polymer is selected from starch grafted with acrylic homopolymers or copolymers, particularly starch grafted with sodium polyacrylate. Specifically, the acrylic polymer can be a homopolymer or copolymer, particularly sodium polyacrylate.

[0031] These polymers have a large capacity to absorb and retain water and aqueous fluids. After absorbing aqueous liquids, the polymer particles thus filled with aqueous fluids remain insoluble in the aqueous fluids and therefore retain their individual particle state.

[0032] Superabsorbent polymers can have water absorption capacities ranging from 20 to 2000 times their own weight (i.e., 20 g to 2000 g of water absorbed per gram of absorbent polymer), preferably 30 to 1500 times, and even more preferably 50 to 1000 times. These water absorption characteristics are defined for distilled water under standard temperature (25°C) and pressure (760 mmHg, i.e., 100,000 Pa). The water absorption capacity of the polymer can be determined by dispersing 0.5 g of the polymer in 150 g of aqueous solution, waiting 20 minutes, filtering the unabsorbed solution through a 150 μm filter for 20 minutes, and weighing the unabsorbed water.

[0033] The superabsorbent polymer used in the compositions of the present invention is in particulate form. Preferably, the superabsorbent polymer has an average size in its dry or unhydrated form that is less than or equal to 100 μm, and more preferably less than or equal to 50 μm, for example, from 1 to 100 μm, more preferably from 5 to 50 μm, and even more preferably from 7 to 30 μm.

[0034] The average size of the particles corresponds to the mass-average diameter (D50), which is measured by laser particle size analysis or another equivalent method known to those skilled in the art. These particles swell upon hydration, forming soft particles with an average size ranging from 10 μm to 2000 μm.

[0035] These polymers are known for their gelling properties and are typically used in a pre-swelled form in an aqueous phase.

[0036] According to a particular embodiment of the invention, the superabsorbent polymers 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.

[0037] According to a particular embodiment of the invention, the number-average molecular weight of the superabsorbent polymer used is greater than 1000 Daltons.

[0038] In particular, mention may be made of starch grafted with acrylic polymers, and especially with sodium polyacrylate, such as those sold by Sanyo Chemical Industries under the name Sanfresh ST-100MC, or those sold by Daito Kasei under the names Makimousse 25, Makimousse 12, or Makimousse 7 (INCI name: sodium polyacrylate grafted starch).

[0039] The superabsorbent polymer used in this invention can be cross-linked or non-cross-linked.

[0040] The superabsorbent polymer used in this invention is preferably an acrylic homopolymer or copolymer, especially starch grafted with sodium polyacrylate, in granular form.

[0041] Preferably, the superabsorbent polymer is selected from starch grafted with an acrylic homopolymer, preferably in granular form with an average size (or average diameter) of less than or equal to 100 micrometers, more preferably in granular form so that the hair does not become stuck together and will have a full appearance.

[0042] In the presence of superabsorbent polymers, the compositions of the present invention can provide a non-wetting and fast-drying feel.

[0043] At the same time, due to the good affinity of the superabsorbent polymer to the skin, the absorbent beads are well fixed, which can bring good oil control effect.

[0044] Advantageously, the superabsorbent polymer is present in the composition in an amount ranging from 0.01% to 5% by weight, preferably from 0.1% to 3% by weight, more preferably from 0.1% to 1% by weight, and most preferably from 0.2% to 0.8% by weight, relative to the total weight of the composition according to the invention.
