AI Technical Summary
Existing water-based cosmetics can easily lead to sticky feeling when increasing viscosity to improve skin unevenness, affecting the uniform application effect, and making it difficult to achieve smooth applications with high viscosity and low viscosity at the same time.
The aqueous cosmetic composition is formed by regulating viscosity and reducing the viscosity by combining crosslinked white alkane elastomers, hydrophobic porous powders, water-soluble thickeners and surfactants with specific HLB values.
While improving skin unevenness such as pores and fine lines, maintain good application effect and low viscosity, achieving high viscosity but non-stick water-based cosmetic applications.

Abstract
Description
[Technical field]
[0001] The present invention relates to an aqueous composition. [Background technology]
[0002] There has been a demand for cosmetics with a high unevenness correction effect that makes skin irregularities such as pores and fine wrinkles less noticeable and makes the skin look smoother. For example, Patent Document 1 describes a cosmetic composition that combines a crosslinked polysiloxane elastomer and light-scattering particles. This uses the crosslinked polysiloxane elastomer to form a film that covers the pores, making them appear flat.
[0003] Patent Document 2 describes that by using a silicone powder consisting of a crosslinked silicone-network silicone block copolymer in combination with a crosslinked polymethyl methacrylate (PMMA) powder in a silicone gel base, it is possible to produce an oil-based cosmetic that has an excellent unevenness correction effect that makes wrinkles, pores, etc. less noticeable, and also has a natural finish, a bare skin feel, and a high level of transparency. Furthermore, Patent Document 3 describes that a cosmetic composition containing an oil wax gel that contains silicone oil and wax causes diffuse reflection of light at wrinkled areas, even without using powder, and effectively fills in the wrinkled areas of the skin, making it possible to temporarily hide wrinkles.
[0004] On the other hand, compositions containing lipophilic porous powders are known as compositions that have the appearance and feel of skin care cosmetics, but can correct unevenness such as pores without using inorganic powders with high concealing power (e.g., Patent Documents 4 to 6). Cosmetics containing lipophilic porous powders have the advantage that the powder absorbs sebum secreted on the skin over time, suppressing the generation of a sticky feeling and maintaining a smooth feeling, and the spherical lipophilic porous powder has the effect of making unevenness on the skin less noticeable visually.

[0005] [Patent Document 1] Special Publication No. 2007-510691 [Patent Document 2] JP 2005-41795 A [Patent Document 3] Special Publication No. 2019-510783 [Patent Document 4] International Publication No. 2017 / 073758 [Patent Document 5] International Publication No. 2018 / 198737 [Patent Document 6] JP 2017-165675 A DISCLOSURE OF THEINVENTION [Problem to be solved by the invention]
[0006] Incidentally, the compositions described in Patent Documents 4 to 6 preferably have a low viscosity if they are to have a similar feel to skin care cosmetics such as serums or milky lotions. On the other hand, there is a demand for high viscosity in the case of makeup cosmetics and the like. Generally, in order to increase the viscosity, a thickener is added or the amount is increased, but this tends to cause stickiness. If the feel after application is sticky, it is difficult to apply the composition evenly to the skin, the effect of correcting unevenness such as pores is reduced, and the makeup tends to last less. As a result of extensive research, the present inventors discovered that by using a combination of specific components, it is possible to reduce stickiness while at the same time synergistically improving viscosity, and thus completed the present invention.
[0007] That is, an object of the present invention is to provide an aqueous composition which has a suitable viscosity but is not sticky, corrects irregularities such as pores, and provides good cosmetic wear. [Means for solving the problem]
[0008] The aqueous composition of the present invention comprises (A) a crosslinked siloxane elastomer; (B) a lipophilic porous powder; (C) an aqueous medium; It includes.
[0009] (B) The lipophilic porous powder preferably contains cross-linked polymethyl methacrylate as a main material.
[0010] The aqueous composition of the present invention preferably further contains (D) a water-soluble thickener.
[0011] The aqueous composition of the present invention further comprises (E) a surfactant, and this surfactant is preferably a polyoxyethylene-polyoxyalkylene alkyl ether block polymer having an HLB value of 9 to 17 or a polyoxyethylene fatty acid glyceryl.
[0012] The aqueous composition of the present invention may further contain (F) a polar oil.
[0013] (F) The polar oil may be an ultraviolet light absorber.
[0014] The ratio of the lipophilic porous powder (B) to the aqueous medium (C) is preferably 0.1 or more.

Furthermore, by blending the (A) component in an amount of 20 mass% or less, the stickiness can be further reduced.
[0032] The component (A) can be one or a combination of two or more selected from the above-mentioned emulsifying crosslinked siloxane elastomers and non-emulsifying crosslinked siloxane elastomers.
[0033] (B) Lipophilic porous powder Examples of lipophilic porous powders to be blended in the aqueous composition of the present invention include crosslinked polymethyl methacrylate and nylon porous powder. These powders may contain other components, such as silica, in an amount of several mass % or less. It is more preferable that the lipophilic porous powder is mainly made of crosslinked polymethyl methacrylate, and the main material means that it may contain other components, such as silica, in an amount of several mass % or less, as described above. In addition, it is preferable that the lipophilic porous powder is spherical. When the powder is spherical, the average particle size is not particularly limited, but is preferably 0.1 to 100 μm, preferably 0.5 to 50 μm, and more preferably about 1 to 20 μm.
[0034] Either a material that is itself lipophilic, or a material that is hydrophilic and coated with a lipophilic substance, such as hydrophobized silica, can be used. In the case of coating, it is preferable that the inside of the pores is also lipophilized.
[0035] The maximum oil absorption capacity of the lipophilic porous powder is preferably 100% by mass or more relative to the powder. This is because the maximum oil absorption capacity is closely related to the porous volume, and the porous form affects the light diffusion. When the maximum oil absorption capacity is 100% by mass or more, the light diffusion effect is sufficient, and a sufficient pore correction effect can be obtained.
[0036] The amount of the lipophilic porous powder is preferably 0.5 to 30% by mass, more preferably 0.5 to 20% by mass, based on the total amount of the composition. When the amount is 0.5% by mass or more, the viscosity can be more appropriately improved, and the pore correction effect and the smooth feeling sustaining effect can be more effectively obtained, while when the amount is 30% by mass or less, good dispersibility of the powder can be ensured.
[0037] (C) Aqueous medium The aqueous medium in the present invention is a medium containing water as a main component, and may be water alone or may contain a lower alcohol and / or a polyhydric alcohol. The term "main component" means that the water content in the aqueous medium is 50% by mass or more.
[0038] The water in the present invention may be ion-exchanged water, purified water, or tap water. Examples of the lower alcohol include ethanol, propanol, and isopropanol. Examples of polyhydric alcohols include dihydric alcohols such as ethylene glycol, propylene glycol, trimethylene glycol, 1,2-butylene glycol, 1,3-butylene glycol, tetramethylene glycol, and 2,3-butylene glycol, and trihydric alcohols such as glycerin.
[0039] The proportion of lower alcohols and polyhydric alcohols in the aqueous medium is preferably 30% by mass or less, and more preferably 25% by mass or less.
[0040] The blending amount of the (C) aqueous medium in the present invention is preferably 10 to 80% by mass based on the total amount of the composition. When the blending amount is 10% by mass or more, the dispersibility of the (B) component in the composition can be improved, and when the blending amount is 80% by mass or less, the cosmetic lasting power can be improved.
[0041] The ratio of the lipophilic porous powder (B) to the aqueous medium (C) is preferably 0.01 or more, more preferably in the range of 0.01-2, and even more preferably in the range of 0.1-1. 0.01 By satisfying the above, the viscosity can be further improved.
[0042] (D) Water-soluble thickener The aqueous composition of the present invention can have a high viscosity due to the components (A) and (B), but may further contain a water-soluble thickener (D) to improve dispersibility. As the water-soluble thickener (D), any thickener that can be generally used in cosmetics can be used.
[0043] Examples of water-soluble thickeners include plant-based polymers such as gum arabic, tragacanth, galactan, carob gum, guar gum, karaya gum, carrageenan, xanthan gum, pectin, agar, quince seed, and algae colloid (brown algae extract); microbial polymers such as dextran, succinoglucan, and pullulan; animal polymers such as collagen, casein, albumin, and gelatin; and starch-based polymers such as starch (rice, corn, potato, and wheat), carboxymethyl starch, and methylhydroxypropyl starch.
[0044] Other examples include cellulose-based polymers such as methyl cellulose, nitrocellulose, ethyl cellulose, methylhydroxypropyl cellulose, hydroxyethyl cellulose, sodium cellulose sulfate, hydroxypropyl cellulose, sodium carboxymethyl cellulose, crystalline cellulose, and cellulose powder; and alginic acid-based polymers such as sodium alginate and propylene glycol alginate.
[0045] Further examples include vinyl polymers such as polyvinyl methyl ether and carboxyvinyl polymers, polyoxyethylene polymers, polyoxyethylene polyoxypropylene copolymer polymers, acrylic polymers such as polyethyl acrylate and polyacrylamide, polyethyleneimine, cationic polymers, bentonite, magnesium aluminum silicate, laponite, hectorite, inorganic water-soluble polymers such as silicic anhydride, PEG-240 / decyltetradeceth-20 / hexamethylene diisocyanate copolymers, (dimethylacrylamide / Na acryloyldimethyltaurate) crosspolymers, (Na acrylate / acryloyldimethyltaurate) copolymers, (alkyl acrylate / steareth-20 methacrylate) copolymers, (ammonium acryloyldimethyltaurate / VP) copolymers, and the like.
[0046] The blending amount of the water-soluble thickener (D) is preferably 0.005 to 2% by mass based on the total amount of the composition. By blending the component (D) in an amount of 0.005% by mass or more, dispersibility and dispersion stability can be improved. In addition, by blending the component (D) in an amount of 2% by mass or less, stickiness can be suppressed.
[0047] (E) Surfactant When a surfactant is blended with the aqueous composition of the present invention (for example, when the aqueous composition is made into an oil-in-water type), it is preferable to use a polyoxyethylene-polyoxyalkylene alkyl ether block polymer or a polyoxyethylene fatty acid glyceryl having an HLB value of 9 to 17, from the viewpoint of low adsorption to component (B) and high contribution to emulsification; in other words, emulsion stability can be ensured even with a small amount of surfactant.
[0048] HLB is calculated by the Kawakami formula, which is expressed by the following formula 1 (where MW represents the molecular weight of the hydrophilic group, and MO represents the molecular weight of the lipophilic group). Additivity is recognized in HLB values, and when two or more nonionic surfactants are used in combination, the overall HLB value is expressed as the weighted average of the HLB values of each individual surfactant.
[0049]
number
[0050] (Polyoxyethylene-polyoxyalkylene alkyl ether block polymer with HLB value of 9-17) An example of the polyoxyethylene-polyoxyalkylene alkyl ether block polymer is the polyoxyethylene-polyoxyalkylene alkyl ether block polymer represented by the following general formula (1).
[0051] RO-(PO) m -(EO) n -H (1)
[0052] In the general formula (1), R1 is a hydrocarbon group having 16 to 18 carbon atoms, and is preferably a saturated or unsaturated aliphatic hydrocarbon group, such as palmityl, stearyl, isostearyl, oleyl, and linolyl. PO is an oxypropylene group, and EO is an oxyethylene group. In general formula (1), PO and EO must be bonded in a block configuration. If they are bonded randomly, sufficient formulation stability cannot be obtained. There is no particular restriction on the order in which propylene oxide and ethylene oxide are added. In addition, the block configuration includes not only two-stage blocks, but also three or more stages. m and n respectively represent the average number of moles of PO and EO added, and are 70>m>4, 70>n>10, and n>m.
[0053] The molecular weight of the block polymer of general formula (1) is preferably 800 or more, more preferably 1500 or more. If the molecular weight is less than 800, the effect is low. Although the upper limit of the molecular weight cannot be particularly specified, a sticky feeling tends to occur as the molecular weight increases. Examples of the block polymer represented by the general formula (1) include "Nikkol PBC44" (HLB=12.5), "Nikkol PBC33" (HLB=10.5), and "Nikkol PBC34" (HLB=16.5), all manufactured by Nikko Chemicals Co., Ltd.

[0055] The blending amount of the component (E) is preferably 0.01 to 5 mass % based on the total amount of the composition, and more preferably 0.5 to 3 mass %. E By making the blending amount of the ) component 0.01% by mass or more and 5% by mass or less, better emulsion stability can be ensured.
[0056] (F) Polar oil The aqueous composition of the present invention may contain a polar oil component (F). By incorporating the surfactant of the component (E) above, the emulsion stability can be further improved even when a polar oil component is incorporated.
[0057] The IOB value of the polar oil is not particularly limited, but is preferably 0.05 to 0.80. The IOB value is an abbreviation for Inorganic / Organic Balance, which is a value that represents the ratio of inorganic values to organic values, and is an index that indicates the degree of polarity of an organic compound. IOB value = inorganic value / organic value Here, for each of the "inorganic value" and "organic value", for example, the "organic value" for one carbon atom in a molecule is 20, and the "inorganic value" for one hydroxyl group in the molecule is 100, the "inorganic value" and "organic value" are set according to various atoms or functional groups, and the IOB value of an organic compound can be calculated by integrating the "inorganic value" and "organic value" of all atoms and functional groups in the organic compound (see, for example, Fujita, "Chemical Region", Vol. 11, No. 10, pp. 719-725, 1957).
