Description

Title of the invention: STABLE, NON-STICKY, AND NON-OILY COMPOSITION WITH TRANSFORMATION PROPERTY TEXTURE FORMATION technical field

[0001] The present invention relates to a composition, preferably a cosmetic composition and, even better, a cosmetic composition for the skin, which is stable and can provide a texture transformation as well as a non-sticky, non-greasy and non-shiny appearance. CONTEXT OF ART

[0002] Giving the skin a comfortable texture is one of the key characteristics of cosmetic products, especially skin care cosmetic products.

[0003] In particular, the transformation of texture (change of texture of a gel or cream, for example, into a liquid, which corresponds to the change in the physical properties of a composition, such as a collapse of the structure of the composition which could allow the liquid to flow out of the composition) which could provide a feeling of freshness at the beginning of application, as well as a non-sticky or reduced sticky feeling after application, are always necessary for consumer satisfaction during use.

[0004] It should be noted that a composition that is unstable and easily causes the structure of the composition to collapse often provides a feeling of comfort during use. This means that it is difficult to offer both a feeling of comfort during use and good stability.

[0005] To date, several technologies relating to gel-type compositions or emulsion compositions that provide improved texture and stability have been reported. For example, WO2022 / 124385 discloses a stable composition that can provide a textural transformation. DISCLOSURE OF THE INVENTION

[0006] However, sufficient research has not yet been carried out for stable compositions which can provide zero or reduced stickiness, as well as a non-greasy / oily or reduced greasy / oily feel, and zero or reduced shine, after application, in addition to texture transformation during application.

[0007] An objective of the present invention is to provide a stable composition that can offer a zero or reduced stickiness, as well as a zero or reduced greasy / oily feel, and a zero or reduced glossy appearance, after application, in addition to the texture transformation during application.

[0008] The above objective can be achieved by a composition, preferably a cosmetic composition and, even better, a cosmetic composition for the skin, comprising:

[0009] (a) at least one cellulose particle;

[0010] (b) at least one associative polymer comprising one or more acrylic motifs and / or methacrylics;

[0011] (c) at least one lipophilic organic UV filter and

[0012] (d) of water.

[0013] The particle size of the (a) cellulose particle may be 50 qm or less, preferably 30 qm or less, and more preferably 10 qm or less.

[0014] The (a) cellulose particle may have

[0015] a wetting point for the oil of at least 40 ml / 100 g, preferably at least 50 ml / 100 g and, even better, at least 60 ml / 100 g, and

[0016] a wetting point for water of at least 100 ml / 100 g, preferably of at least 200 ml / 100 g and, even better, of at least 300 ml / 100 g.

[0017] The ratio between the wetting point for water and the wetting point for oil of the (a) cellulose particle may be less than or equal to 5, preferably less than or equal to 4 and, even better, less than or equal to 2.

[0018] The (a) cellulose particle can be spherical.

[0019] The quantity of (c) cellulose particle in the composition according to the present invention may be between 0.1% and 20% by weight, preferably between 0.5% and 15% by weight and, even better, between 1% and 10% by weight, relative to the total weight of the composition.

[0020] The (b) associative polymer may comprise one or more (C1-C12) alkyl ester motifs of (meth)acrylic acid.

[0021] The (b) associative polymer may comprise one or more motifs derived from polyoxyalkylated fatty alcohols.

[0022] The quantity of the (b) associative polymer(s) in the composition according to the present invention can be from 0.01% to 10% by weight, preferably from 0.05% to 5% by weight and, even better, from 0.1% to 1% by weight, relative to the total weight of the composition.

[0023] The (c) lipophilic organic UV filter may be selected from the group consisting of dro-metrizole trisiloxane, bis(ethylhexyloxyphenol)methoxyphenyltriazine, ethylhexyl triazone, diethylamino hydroxybenzoyl hexyl benzoate, butyl methoxyben-zoylmethane, ethylhexyl methoxycinnamate, ethylhexyl salicylate, octocrylene, ho-mosalate and a mixture thereof.

[0024] The quantity of (c) lipophilic organic UV filters in the composition according to the the present invention can be from 1% to 30% by weight, preferably from 3% to 25% by weight and, better still, from 5% to 20% by weight, relative to the total weight of the composition.

[0025] The composition according to the present invention may further comprise (e) at least one non-ionic surfactant, preferably selected from fatty acid polyglyceryl esters and, even better, fatty acid polyglyceryl monoesters.

[0026] The quantity of (e) nonionic surfactant(s) in the composition according to the present invention can be from 0.01% to 5% by weight, preferably from 0.05% to 3% by weight and, even better, from 0.1% to 1% by weight, relative to the total weight of the composition.

[0027] The composition according to the present invention may further comprise (f) at least one oil other than (c) the lipophilic organic UV filter.

[0028] The present invention also relates to a cosmetic process for treating a keratinous substance, comprising the step of applying the composition according to the present invention to the keratinous substance. Best embodiment of the invention

[0029] After careful research, the inventors discovered a new approach to providing a stable composition that can provide a non-sticky or reduced stickiness, as well as a non-greasy / oily or reduced greasy / oily feel, and a non-existent or reduced glossy appearance, after application, in addition to the transformation of the texture during application.

[0030] Thus, one aspect of the present invention is a composition, comprising:

[0031] (a) at least one cellulose particle;

[0032] (b) at least one associative polymer comprising one or more acrylic motifs and / or methacrylics;

[0033] (c) at least one lipophilic organic UV filter and

[0034] (d) of water.

[0035] The composition according to the present invention is stable and can provide a zero or reduced stickiness, as well as a zero or reduced oily / greasy feel, and a zero or reduced glossy appearance, after application, in addition to the transformation of the texture during application.

[0036] The composition according to the present invention is stable immediately after preparation and for a long period after preparation, even when subject to temperature changes from cold to hot. Therefore, the composition according to the present invention is stable over time and can be stored for extended periods even with temperature fluctuations between winter and summer.

[0037] The composition according to the present invention may not provide any sticky sensation or a reduced sticky feeling, preferably after application.

[0038] The term “sticky” here means a property which gives a sticky sensation to the skin.

[0039] The composition according to the present invention includes the (c) lipophilic organic UV filter which has properties similar to those of oil and the (c) lipophilic organic UV filter itself can, after application, cause a greasy or oily feeling and a shiny appearance such as shiny skin.

[0040] However, the composition according to the present invention can provide a non-greasy or oily or reduced greasy or oily feel, and a non-existent or reduced glossy appearance, such as shiny skin, although the composition includes the (c) lipophilic organic UV filter.

[0041] The composition according to the present invention can bring about a textural transformation during application, preferably at an early stage of application. Textural transformation here means a change in the texture of a gel or cream, for example, into a liquid, which corresponds to a change in the physical properties of a composition, such as a breakdown of the composition's structure that could allow the liquid to flow from the composition. The textural transformation can provide a sensation of freshness.

[0042] Therefore, the composition according to the present invention can provide an excellent tactile sensation, in particular for the sensation of the skin during and after the application of the composition.

[0043] The composition according to the present invention and similar will be explained in more detail below.

[0044] [Cellulose particle]

[0045] The composition according to the present invention includes (a) at least one cellulose particle with specific properties. If two or more cellulose particles are used, they may be identical or different.

[0046] The particle size of (a) cellulose particle corresponds to a primary particle size. Furthermore, particle size here refers to an average size or particle average, which may be a volume average size, which can be determined, for example, by a laser diffraction particle size analyzer.

[0047] The particle size of the cellulose particle (a) used for the present invention is not limited. However, it is preferable that the particle size of the cellulose (a) be 50 µm or less, preferably 30 µm or less, better still 15 µm or less, even better 10 µm or less, and particularly 2 to 5 µm.

[0048] It is preferable that 90% or more of the vol. of the (a) cellulose particles used for the present invention have an average primary particle size ranging from 0.1 to 10 pm, preferably from 0.5 to 8 pm and, even better, from 1 to 7 pm. If 90% or more by volume of (a) the cellulose particles have an average primary particle size ranging from 1 to 7 pm, optical effects due to the particles can also be obtained.

[0049] The (a) cellulose particle used for the present invention can be in any particle form.

[0050] It is preferable that the ratio between the longest diameter / shortest diameter of the (a) cellulose particle used for the present invention be in the range of 1.0 to 10, preferably 1.0 to 5 and, even better, 1.0 to 3.

[0051] It is preferable that the (a) cellulose particle be spherical, preferably with a ratio of longest diameter / shortest diameter of 1.0 to 1.1.

[0052] The (a) cellulose particle used for the present invention may have

[0053] a wetting point for the oil of at least 40 ml / 100 g, preferably at least 50 ml / 100 g, better still at least 60 ml / 100 g, better still at least 100 ml / 100 g, and even better still at least 250 ml / 100 g, and preferably at least 1500 ml / 100 g; and

[0055] The expression "oil wetting point" in the specification refers to an amount of oil required to make a target powder completely wet, which can be recognized, in particular, by the formation of a paste with the target powder.

[0056] The wetting point for the oil can be determined by the following protocol. 1. 2 g of a target powder are mixed using a spatula on a plate of glass while adding oil, especially linear ester oil, such as isononyl isononanoate (WICKENOL 151 / ALZO). 2. When the target powder becomes completely wet and begins to form a paste, the weight of the added oil is determined as the weight at the wetting point. 3. The wetting point for the oil is calculated from the following equation: wetting point for the oil (ml / 100 g) = {(weight at the wetting point) / 2 g]X100 / density of the oil.

[0057] Similarly, the expression "wetting point for water" in the specification refers to an amount of water required to make a target powder completely wet, which can be recognized, in particular, by the formation of a paste with the target powder.

[0058] The mooring point for the water can be determined by the following protocol. 1. 2 g of a target powder are mixed using a spatula on a plate of glass while adding water with a density of 0.998 g / ml. 2. When the target powder becomes completely wet and begins to form a paste, the weight of the added water is determined as the weight at the wetting point. 3. The wetting point for water is calculated from the following equation: Wetting point for water (ml / 100 g) = {(weight at wetting point) / 2 g}X100 / density of water.

[0059] It is preferable that the ratio of the water wetting point / oil wetting point of the (a) cellulose particle used for the present invention be 5 or less, preferably 4 or less, better still 3 or less, and even better still 2 or less, and preferably 0.1 or more.

[0060] The (a) cellulose particle may be porous or non-porous, preferably porous.

[0061] The porosity of the (a) cellulose particle can be characterized by a specific surface area of ​​0.05 m2 / g to 1,500 m2 / g, better still of 0.1 m2 / g to 1,000 m2 / g, and even better still of 0.2 m2 / g to 500 m2 / g according to the BET method.

[0062] In the present invention, the cellulose that can be used for the (a) cellulose particle is not limited by types of cellulose such as cellulose I, cellulose II, or the like. As a cellulose that can be used as a material for the (a) cellulose particle for the present invention, type II cellulose is preferable.

[0063] The (a) cellulose particle, preferably a spherical cellulose particle, can be prepared, for example, as follows. 1. A suspension of calcium carbonate, as an aggregation inhibitor, is added to an alkaline aqueous solution of water-soluble anionic polymer, and then stirred. 2. The viscose and the aqueous solution obtained in the preceding (1) are mixed to form a dispersion of fine viscose particles. 3. The dispersion of fine viscose particles obtained in the preceding (2) is heated to aggregate the viscose in the dispersion, and neutralized with acid, to form fine cellulose particles. 4. The fine cellulose particles are separated from the mother liquid obtained in point 3 above and washed and dried, if necessary.

[0064] Viscose is a raw material for cellulose. It is preferable to use viscose with a gamma value of 30 to 100% by mass and an alkaline concentration of 4 to 10% by mass. Examples of the above-mentioned water-soluble anionic polymer include the sodium salt of polyacrylic acid, the sodium salt of polystyrene sulfonic acid, and the like. The above-mentioned calcium carbonate is used to prevent the aggregation of fine viscose particles in the dispersion and to reduce the size of the cellulose particles. Examples of calcium carbonate paste include Tama Pearl TP-221GS marketed by Okutama Kogyo Co., Ltd. in Japan.

[0065] According to one embodiment, the (a) cellulose particle may or may not include a cellulose derivative. The cellulose derivative may be selected from cellulose esters and ethers.

[0066] It is indicated that the term "cellulose ester" designates, in the text above and below, a polymer consisting of an a (1-4) sequence of partially or totally esterified anhydroglucose rings, the esterification being obtained by reaction of all or part of the free hydroxyl functions of said anhydroglucose rings with a linear or branched carboxylic acid or a carboxylic acid derivative (acid chloride or acid anhydride) containing 1 to 4 carbon atoms.

[0067] Preferably, the cellulosic ester results from the reaction of some of the free hydroxyl functions of said rings with a carboxylic acid containing 1 to 4 carbon atoms.

[0068] Advantageously, the cellulose esters are selected from cellulose acetates, propionates, butyrates, isobutyrates, acetobutyrates and acetopropionates and mixtures thereof.

[0069] These cellulosic esters can have an average molecular mass by weight ranging from 3,000 to 1,000,000, preferably from 10,000 to 500,000 and, even better, from 15,000 to 300,000.

[0071] Cellulose ethers are therefore preferably chosen from cellulose alkyl ethers with an alkyl group containing 1 to 4 carbon atoms, such as cellulose methyl, propyl, isopropyl, butyl and isobutyl ethers.

[0072] These cellulose ethers can have a weight average molecular mass ranging from 3,000 to 1,000,000, preferably from 10,000 to 500,000 and even better from 15,000 to 300,000.

Silicones belonging to this category are also described in the article published in Cosmetics and Toiletries, Vol. 91, Jan. 76, pp. 27–32, Todd & Byers, Volatile Silicone Fluids for Cosmetics. The viscosity of the silicones is measured at 25 °C in accordance with ASTM 445 Annex C.

[0345] Non-volatile polydialkylsiloxanes can also be used. These non-volatile silicones are more particularly chosen from among the polydialkylsiloxanes, among which the main examples are polydimethylsiloxanes containing trimethylsilyl terminal groups.

Thus, the composition according to the present invention can provide, in particular, an excellent feel and stability over a long period, even under temperature changes.

[0512] The composition according to example 2 is more preferable than the composition according to example 1, due to the presence of the ingredient (g) (silica particles), in terms of non-sticky feeling, non-greasy / oily feeling and non-shiny appearance, after application.

[0513] On the other hand, compositions according to comparative example 1 which did not include ingredient (a) (cellulose particles) showed inferior texture transformation, a sticky, oily / greasy feel and a shiny appearance as well as instability.

[0514] The composition according to comparative example 2 which did not include ingredient (b) (beheneth-25 acrylates / methacrylate copolymer) could not be thickened well and showed inferior texture transformation and instability.
