Description

[Technical field]

[0001] The present invention relates to a composition, preferably a cosmetic composition, more preferably a skin cosmetic composition, which is stable and capable of providing a non-sticky, non-oily and non-shiny appearance along with texture transformation. [Background technology]

[0002] Providing a pleasant texture to the skin is one of the main properties of a cosmetic product, in particular a skin care cosmetic product.

[0003] In particular, texture transformation (a change in the physical properties of the composition, e.g. a change in texture from gel or cream to liquid, corresponding to a breakdown in the structure of the composition, whereby the liquid can flow out of the composition), which can provide a fresh sensation at the initial stage of application as well as a non-sticky or reduced sticky feel after application, remains necessary for customer satisfaction during use.

[0004] It should be noted that compositions that are unstable and easily cause the composition's structure to collapse often provide a pleasant feel in use, which means that it is difficult to provide both a pleasant feel in use and good stability at the same time.

[0005] To date, several techniques have been reported for gel-like or emulsion compositions that provide improved texture and stability. For example, WO2022 / 124385 discloses a stable composition that can provide texture transformation.

[0006] However, there has not yet been sufficient research into stable compositions that can provide texture transformation during application as well as no or reduced sticky feel, no or reduced oily / greasy feel, and no or reduced glossy appearance after application.

[0025] After extensive investigation, the inventors have discovered a new approach to provide stable compositions that can provide texture transformation during application as well as no or reduced sticky feel, no or reduced oily / greasy feel, and no or reduced glossy appearance after application.

[0026] Thus, one aspect of the present invention is (a) at least one cellulose particle; (b) at least one associative polymer comprising one or more acrylic and / or methacrylic units; (c) at least one lipophilic organic UV filter, and (d) water A composition comprising:

[0027] The compositions according to the invention are stable and can provide a texture transformation during application as well as no or reduced sticky feel after application, no or reduced oily / greasy feel, and a no or reduced glossy appearance.

[0028] The composition according to the invention is stable for a long time after the composition is prepared, both immediately after the composition is prepared and even under temperature changes from cold to hot. Therefore, the composition according to the invention is stable over time and can be stored for a long period of time even under temperature changes that occur from winter to summer.

[0029] The compositions according to the present invention preferably do not produce a sticky feel or can reduce a sticky feel after application.

[0030] The term "tacky" as used herein means the property of providing a sticky feel to the skin.

[0031] The composition according to the invention comprises (c) a lipophilic organic UV filter which has properties similar to those of an oil and which as such can cause an oily or greasy feel and a shiny appearance, e.g. shiny skin, after application.

[0032] However, the composition according to the present invention, despite comprising (c) a lipophilic organic UV filter, does not result in or can reduce an oily or greasy feel and a shiny appearance, e.g. shiny skin.

[0033] The composition according to the invention can provide texture transformation during application, preferably at the initial stage of application.Texture transformation means here a change in the physical properties of the composition, for example a change in texture from gel or cream to liquid, which corresponds to a breakdown in the structure of the composition, and allows the liquid to flow out of the composition.Texture transformation can provide a refreshing sensation.

[0034] Therefore, the composition according to the present invention can provide an excellent feel to the skin, particularly during and after application of the composition.

[0035] Hereinafter, the compositions according to the present invention will be described in more detail.

[0036] [Cellulose particles] The composition according to the invention comprises (a) at least one type of cellulose particles having specific properties. When two or more types of cellulose particles are used, these may be the same or different.

[0037] (a) The particle size of the cellulose particles corresponds to the primary particle size. In addition, particle size here means the average, i.e. arithmetic mean particle size, which may be the volume-average particle size, which can be determined, for example, by a laser diffraction particle size analyzer.

[0038] The particle size of the (a) cellulose particles used in the present invention is not limited, but is preferably 50 μm or less, more preferably 30 μm or less, more preferably 15 μm or less, even more preferably 10 μm or less, and particularly preferably 2 to 5 μm.

[0039] It is preferred that 90% by volume or more of the (a) cellulose particles used for the present invention have an average primary particle size in the range of 0.1 to 10 μm, preferably 0.5 to 8 μm, more preferably 1 to 7 μm. When 90% by volume or more of the (a) cellulose particles have an average primary particle size in the range of 1 to 7 μm, optical effects attributable to the particles can also be achieved.

[0040] The (a) cellulose particles used for the present invention may be in any particulate form.

[0041] The ratio of the longest diameter to the shortest diameter of the cellulose particles (a) used in the present invention is preferably within the range of 1.0-10, more preferably 1.0-5, and even more preferably 1.0-3.

[0042] The (a) cellulose particles are spherical, and more preferably have a ratio of longest diameter to shortest diameter of 1.0 to 1.1.

[0043] The cellulose particles (a) used for the present invention are a wet point for oil of at least 40 ml / 100 g, preferably at least 50 ml / 100 g, more preferably at least 60 ml / 100 g, more preferably at least 100 ml / 100 g, even more preferably at least 250 ml / 100 g, and preferably not more than 1500 ml / 100 g; and a water wetting point of at least 100 ml / 100 g, preferably at least 200 ml / 100 g, more preferably at least 300 ml / 100 g, even more preferably at least 350 ml / 100 g, and preferably not more than 1500 ml / 100 g; may have.

[0044] The term "wetting point for oil" as used herein means the quantity or amount of oil required to completely wet a powder of interest, particularly as can be appreciated by the formation of a paste with the powder of interest.

[0045] The wetting point for oil can be determined by the following protocol. (1) 2 g of the target powder is kneaded on a glass plate using a spatula while adding oil, particularly a linear ester oil, such as isononyl isononanoate (WICKENOL 151 / ALZO). (2) Once the desired powder is completely wetted and begins to form a paste, the mass of oil added is determined as the mass at the wetting point. (3) Calculate the wetting point for oil from the following formula: Wetting point for oil (ml / 100 g) = {(mass of wetting point) / 2 g} x 100 / density of oil.

[0046] Similarly, the term "water wetting point" as used herein means the quantity or amount of water required to completely wet a powder of interest, which may be realized in particular by forming a paste with the powder of interest.

[0047] The wetting point for water can be determined by the following protocol. (1) 2 g of the desired powder is kneaded with a spatula on a glass plate while adding water having a density of 0.998 g / ml. (2) When the desired powder is completely wetted and begins to form a paste, the mass of water added is determined as the mass at the wetting point. (3) Calculate the wetting point for water using the following formula: Wetting point for water (ml / 100 g) = {(mass at wetting point) / 2 g} x 100 / density of water.

[0048] The (a) cellulose particles used for the present invention preferably have a water wetting point / oil wetting point ratio of 5 or less, preferably 4 or less, more preferably 3 or less, even more preferably 2 or less, and preferably 0.1 or more.

[0049] The (a) cellulose particles may be porous or non-porous, and are preferably porous.

[0050] (a) The porosity of cellulose particles is measured by the BET method at 0.05 m 2 / g~1,500m 2 / g, more preferably 0.1m 2 / g~1,000m 2 / g, more preferably 0.2m 2 / g~500m 2 The specific surface area may be characterized in terms of specific surface area in g / g.

[0051] In the present invention, the cellulose that can be used for (a) cellulose particles is not limited by the type of cellulose, such as cellulose I or cellulose II. As the cellulose that can be used as the material for (a) cellulose particles for the present invention, type II cellulose is preferred.

[0052] (a) Cellulose particles, preferably spherical cellulose particles, can be prepared, for example, as follows. (1) A slurry of calcium carbonate as a flocculation inhibitor is added to an aqueous solution of an alkaline water-soluble anionic polymer and stirred. (2) Viscose is mixed with the aqueous solution obtained in (1) above to form a dispersion of viscose microparticles. (3) The dispersion of viscose microparticles obtained in (2) above is heated to aggregate the viscose in the dispersion, and neutralized with an acid to form cellulose microparticles. (4) The cellulose microparticles are separated from the mother liquor obtained in (3) above, washed as necessary, and dried.

[0053] Viscose is a raw material for cellulose. It is preferable to use viscose having a gamma value of 30 to 100% by mass and an alkali concentration of 4 to 10% by mass. Examples of the water-soluble anionic polymer include sodium polyacrylate and sodium polystyrene sulfonate. The calcium carbonate is used to prevent aggregation of viscose fine particles in the dispersion and to reduce the particle size of the cellulose particles. Examples of calcium carbonate slurry include Tama Pearl TP-221GS, which is commercially available from Okutama Kogyo Co., Ltd. of Japan.

[0054] According to one embodiment, the (a) cellulose particles may or may not contain a cellulose derivative, which may be selected from cellulose esters and ethers.

[0055] The term "cellulose ester" is used above and in the following text to denote a polymer consisting of an α(1-4) sequence of partially or completely esterified anhydroglucose rings, the esterification being obtained by reacting all or only a part of the free hydroxyl functions of said anhydroglucose rings with linear or branched carboxylic acids or carboxylic acid derivatives (acid chlorides or acid anhydrides) containing 1 to 4 carbon atoms.

[0056] Preferably, the cellulose ester is obtained by reacting some of the free hydroxyl functions of said ring with a carboxylic acid containing from 1 to 4 carbon atoms.

[0057] Advantageously, the cellulose ester is chosen from cellulose acetate, cellulose propionate, cellulose butyrate, cellulose isobutyrate, cellulose acetobutyrate and cellulose acetopropionate, and mixtures thereof.

[0058] These cellulose esters may have a mass average molecular weight within the range of 3,000 to 1,000,000, preferably 10,000 to 500,000, and more preferably 15,000 to 300,000.

[0059] In the above and following text, the term "cellulose ether" means a polymer consisting of an α(1-4) sequence of partially etherified anhydroglucose rings, in which some of the free hydroxyl functions of said rings are replaced by -OR groups, R being preferably a linear or branched alkyl group containing from 1 to 4 carbon atoms.

[0060] Thus, the cellulose ether is preferably selected from cellulose alkyl ethers having an alkyl group containing from 1 to 4 carbon atoms, such as cellulose methyl, propyl, isopropyl, butyl and isobutyl ethers.

[0061] These cellulose ethers may have a mass average molecular weight within the range of 3,000 to 1,000,000, preferably 10,000 to 500,000, and more preferably 15,000 to 300,000.
