Description

[Technical Field]

[0001] The present invention relates to a liquid water-in-oil emulsion cosmetic composition. [Background technology]

[0002] Ultraviolet rays are the main cause of skin aging, causing the appearance of skin imperfections such as age spots, wrinkles, and freckles. Daily cosmetics such as foundation are expected to prevent UV-induced skin damage in order to prevent and delay skin aging. Known cosmetic compositions designed for UV protection include those containing inorganic UV blockers (Korean Patent Application No. 1020160107064, International Patent Publication No. WO2019 / 98805).

[0003] Furthermore, cosmetics generally require high makeup effects such as excellent coverage, long-lasting effect, and high stability. Summary of the Invention [Problem to be solved by the invention]

[0004] However, when the amount of UV scattering agent or UV absorber in a cosmetic product is increased to enhance the UV protection effect, the powdery feeling of the UV scattering agent is emphasized, or the stickiness caused by the UV absorber occurs, resulting in problems in terms of finish. UV scattering agents and UV absorbers have also brought about undesirable results in terms of makeup effect and stability.

[0005] An object of the present invention is to provide a cosmetic product that contains an ultraviolet scattering agent or an ultraviolet absorbing agent and yet exhibits excellent covering power, a comfortable finish, long-lasting effects, and high stability. [Means for solving the problem]

[0006] The present invention provides a water-in-liquid oil emulsion cosmetic composition comprising: a) a non-volatile liquid oil, b) a water-soluble UV filter, c) an inorganic UV filter, d) a volatile hydrocarbon oil, and e) a fatty acid ester nonionic surfactant having an HLB value of less than 8, wherein component e) comprises a polyglycerin fatty acid ester surfactant and a sorbitan fatty acid ester surfactant.

[0007] One of the features of the present cosmetic composition is that it contains both a polyglycerin fatty acid ester surfactant and a sorbitan fatty acid ester surfactant as component e). The effects of the present invention, i.e., excellent coverage, comfortable finish, long-lasting effect, and high stability, are believed to be due to the inclusion of component e) and its combination with other ingredients. As used herein, "stability" refers to the uniform appearance of the composition. The polyglycerin fatty acid ester surfactant is important for the cosmetic composition to form an emulsified state. The sorbitan fatty acid ester surfactant is important for achieving a comfortable finish and maintaining the emulsion stability of the cosmetic composition. The present cosmetic composition can be formulated without the addition of a silicone-based surfactant, resulting in a more comfortable finish when applied to the skin.

[0008] The cosmetic composition also contains component d). The cosmetic composition exhibits excellent coverage, long-lasting effect, and a light finish when applied to the skin, and these effects are believed to be due to the inclusion of component d) and the combination of component d) with other ingredients. The cosmetic composition may not contain a volatile silicone oil, which can further enhance the stability of the cosmetic composition.

[0009] This cosmetic composition exhibits excellent coverage and excellent UV protection when applied to the skin. The presence of component c) is believed to contribute to the superior coverage, and the presence of both component b) and component c) is believed to contribute to the higher UV protection effect.

[0035] A cosmetic composition according to one embodiment comprises component a) a non-volatile liquid oil.

[0036] A non-volatile liquid oil is a non-evaporative oil component that is liquid at room temperature (15 to 25°C) and atmospheric pressure (1 atmosphere). More specifically, a non-volatile liquid oil is an oil component that exhibits a mass loss value (Equation (1)) of less than 4% by mass after drying for 60 minutes at 33°C and 55% humidity according to the following protocol.

[0037] Component a) may be, for example, a non-volatile hydrocarbon oil, a higher alcohol, an ester oil, an ether oil or a vegetable oil.

[0038] Examples of non-volatile hydrocarbon oils include squalane, liquid paraffin, polybutene, polyisobutene, hydrogenated polyisobutene, hydrogenated polydecene, and olefin oligomers.

[0039] The higher alcohol is an aliphatic monoalcohol having 6 or more carbon atoms, and preferably an aliphatic monoalcohol having 12 to 28 carbon atoms. Examples of the higher alcohol include octyl alcohol, dodecyl alcohol, oleyl alcohol, octyldodecanol, hexyldecanol, isostearyl alcohol, and decyltetradecanol.

[0040] Ester oils are carboxylic acid esters that are liquid and do not vaporize under normal temperature and pressure conditions (e.g., 25°C, 1 atmosphere), and are preferably carboxylic acid alkyl esters in which the carboxylic acid or alcohol constituting the ester has 8 to 18 carbon atoms. Examples of ester oils include propylene glycol fatty acid esters such as propylene glycol dicaprylate and propylene glycol dicaprate; fatty acid alkyl esters such as isoamyl laurate, hexyl laurate, ethylhexyl palmitate, isopropyl myristate, 2-octyldodecyl myristate, cetyl 2-ethylhexanoate, isononyl isononanoate, and isotridecyl isononanoate; carbonates such as dicaprylyl carbonate; tri- or higher fatty acid esters of polyglycerin such as polyglyceryl-2 triisostearate, polyglyceryl-2 tetraisostearate, and polyglyceryl-10 decaisostearate; glyceryl tri-2-ethylhexanoate, glyceryl tribehenate, and tri(caprylic / capric)glyceryl; Examples include glycerin tri-fatty acid esters (also known as triglyceride oils) such as triheptanoin; benzoic acid derivatives such as diisostearyl malate and C12-15 alkyl benzoate; salicylic acid derivatives such as homosalate and ethylhexyl salicylate; alkyl esters such as coco-caprylate / coco-caprate; cinnamic acid derivatives such as octyl methoxycinnamate, isopropyl methoxycinnamate, isoamyl methoxycinnamate, cinnoxate, DEA methoxycinnamate, diisopropyl methylcinnamate, glyceryl ethylhexanoate-dimethoxycinnamate, and di-(2-ethylhexyl)-4'-methoxybenzalmalonate; and beta, beta-diphenylacrylate derivatives such as octocrylene.

[0043] Among the non-volatile liquid oils described above, ethylhexyl salicylate, octyl methoxycinnamate, homosalate, octocrylene, etc. function as oil-soluble organic UV filters. That is, a cosmetic composition according to one embodiment may contain an oil-soluble organic UV filter. The oil-soluble organic UV filter has the effect of absorbing ultraviolet rays and thereby preventing them from reaching the skin.

[0044] The content of component a) may be, based on the total mass of the cosmetic composition, 1 to 45 mass%, 3 to 45 mass%, 5 to 45 mass%, 10 to 45 mass%, 1 to 40 mass%, 3 to 40 mass%, 5 to 40 mass%, 10 to 40 mass%, 1 to 35 mass%, 3 to 35 mass%, 5 to 35 mass%, 10 to 35 mass%, 1 to 30 mass%, 3 to 30 mass%, 5 to 30 mass%, 10 to 30 mass%, 1 to 25 mass%, 3 to 25 mass%, 5 to 25 mass%, 10 to 25 mass%, 1 to 20 mass%, 3 to 20 mass%, 5 to 20 mass%, or 10 to 20 mass%. When the content of component a) is 1 mass% or more, a higher moisturizing effect is exhibited, and as the content of component a) increases, up to at least 45 mass%, an even higher moisturizing effect tends to be exhibited. If the content of component a) is 45% by mass or less, the cosmetic layer formed is less likely to plasticize, resulting in a longer-lasting effect. As the content of component a) decreases, the longer-lasting effect tends to increase further, at least up to 1% by mass.

[0045] The cosmetic composition according to one embodiment also contains component b) a water-soluble UV filter.

[0046] Examples of water-soluble UV filters include benzophenone-based ultraviolet absorbers such as 2-hydroxy-4-methoxybenzophenone-5-sulfonate; benzylidene camphor-based ultraviolet absorbers such as benzylidene camphorsulfonic acid and terephthalidene discamphorsulfonic acid; and phenylbenzimidazole-based ultraviolet absorbers such as phenylbenzimidazolesulfonic acid.

[0047] Among water-soluble UV filters, for example, phenylbenzimidazole sulfonic acid and the like must be neutralized before use. Even if the filter is not phenylbenzimidazole sulfonic acid, substances known to require neutralization before use are preferably neutralized before use. Neutralization can be carried out according to a conventional method, and the neutralizer may be added so that the pH of the mixture of phenylbenzimidazole sulfonic acid and the neutralizer is 6.0 to 8.0 at room temperature.

When the content of component b) is 0.10 mass% or more, a higher UV protection effect is exhibited, and as the content of component b) increases, up to at least 10 mass%, an even higher UV protection effect tends to be exhibited. If the content of component b) is 10% by mass or less, the freshness and compatibility with the skin when applied to the skin are further improved, and as the content of component b) decreases, the freshness and compatibility with the skin tend to further increase up to at least 0.10% by mass.

[0049] The cosmetic composition according to one embodiment also contains component c) an inorganic UV filter. Inorganic UV filters are clearly distinguished from pigments that do not have UV protection properties and pigments whose primary purpose is coloring.

[0059] When the surface and / or interior of component c) is subjected to a hydrophobic treatment, in addition to the above-mentioned hydrophobic treatment, it may be treated with a surface treatment agent such as aluminum hydroxide, alumina, or silica. When the inorganic UV filter has catalytic activity, aluminum hydroxide is particularly effective for blocking the catalytic activity.

[0061] The content of component c) may be 1.0 to 40 mass%, 5.0 to 40 mass%, 7.0 to 40 mass%, 9.0 to 40 mass%, 10 to 40 mass%, 15 to 40 mass%, 1.0 to 35 mass%, 5.0 to 35 mass%, 7.0 to 35 mass%, 9.0 to 35 mass%, 10 to 35 mass%, 15 to 35 mass%, 1.0 to 30 mass%, 5.0 to 30 mass%, 7.0 to 30 mass%, 9.0 to 30 mass%, 10 to 30 mass%, 15 to 30 mass%, 1.0 to 25 mass%, 5.0 to 25 mass%, 7.0 to 25 mass%, 9.0 to 25 mass%, 10 to 25 mass%, or 15 to 25 mass%, based on the total mass of the cosmetic composition. If the content of component c) is 1.0% by mass or more, a higher UV protection effect is exhibited, and as the content of component c) increases, an even higher UV protection effect tends to be exhibited up to at least 40% by mass. If the content of component c) is 40% by mass or less, the powdery feeling when applied to the skin can be further reduced, and as the content of component c) decreases, the powdery feeling tends to be further reduced up to at least 1.0% by mass.

[0062] The cosmetic composition according to one embodiment contains component d) a volatile hydrocarbon oil.

[0063] "Volatile oil" refers to an oil that loses 4% or more of its mass after drying for 60 minutes at 33°C and 55% humidity according to the following protocol: 20 mg of the oil under investigation is weighed onto a 5 cm x 5 cm polymethyl methacrylate (PMMA) plate using a micropipette and precision balance. The oil under investigation is spread over the entire plate with a finger. The plate is then placed in a thermostatically controlled ventilation system at 33°C and 55% humidity. Three tests are performed for each oil. The mass loss during drying is measured after 60 minutes. The mass loss value is expressed according to the following equation (1): Mass loss value (%) = (m t0 -m tx )×100 / m t0 ...Equation (1)

[0064] In formula (1), m tx represents the mass of the plate measured 60 minutes after the start of drying, and m t0 represents the mass of the plate measured before drying. Volatile hydrocarbon oils are liquid at room temperature and pressure and can also be considered as oily components that gradually evaporate.

[0065] Component d) may contain a volatile linear hydrocarbon oil or a volatile branched hydrocarbon oil. Component d) may further contain a volatile hydrocarbon oil having 8 to 19 carbon atoms. Component d) may be one or more selected from branched C8-C16 alkanes (isoparaffin, isododecane, isodecane, isohexadecane, etc.), linear C8-C16 alkanes (nonane, decane, undecane, dodecane, tridecane, pentadecane, hexadecane, etc.), C9-C17 alkane mixtures, C10-C14 alkane mixtures, mixtures of undecane and tridecane, C15-C19 alkane mixtures, C9-C12 alkane mixtures, C12-C14 alkane mixtures, n-dodecane, and n-tetradecane. Component d) may contain a volatile linear or branched hydrocarbon having 9 to 12 carbon atoms, a volatile linear or branched hydrocarbon having 13 to 15 carbon atoms, or a mixture thereof.

[0066] Oils with a mass loss value of 4% or more and 30% or less can be called "slightly volatile oils." Slightly volatile oils include isohexadecane, pentadecane, hexadecane, C13-15 alkanes, and C15-19 alkanes. When a cosmetic composition contains a slightly volatile oil, the smoothness of the cosmetic composition tends to be improved.

[0067] Oils with a mass loss value of 30% or more and 80% or less can be called "medium-volatile oils." Medium-volatile oils include undecane, dodecane, tridecane, and C9-12 alkanes (straight-chain). When a cosmetic composition contains a medium-volatile oil, the balance between the smoothness of the cosmetic composition and its adhesion to the skin is improved.

[0068] Oils with a mass loss value of 80% or more can be called "highly volatile oils." Highly volatile oils include nonane, decane, isododecane, and C9-12 alkanes (branched). When a cosmetic composition contains a highly volatile oil, the cosmetic composition tends to have improved adhesion to the skin.

[0069] The content of component d) may be 1.0 to 30 mass%, 2.0 to 30 mass%, 3.0 to 30 mass%, 4.0 to 30 mass%, 5.0 to 30 mass%, 1.0 to 25 mass%, 2.0 to 25 mass%, 3.0 to 25 mass%, 4.0 to 25 mass%, 5.0 to 25 mass%, 1.0 to 20 mass%, 2.0 to 20 mass%, 3.0 to 20 mass%, 4.0 to 20 mass%, 5.0 to 20 mass%, 1.0 to 15 mass%, 2.0 to 15 mass%, 3.0 to 15 mass%, 4.0 to 15 mass%, 5.0 to 15 mass%, 1.0 to 13 mass%, 2.0 to 13 mass%, 3.0 to 13 mass%, 4.0 to 13 mass%, or 5.0 to 13 mass%, based on the total amount of the cosmetic composition. When the content of component d) is 1.0% by mass or more, the viscosity of the cosmetic composition can be maintained low, making it possible to form a thinner cosmetic layer. As the content of component d) increases, the formation of a thinner cosmetic layer tends to become possible up to at least 30% by mass. When the content of component d) is 30% by mass or less, it becomes easier to maintain the appropriate viscosity of the cosmetic composition, making it possible to further improve product stability. As the content of component d) decreases, product stability tends to further improve up to at least 1.0% by mass. Cosmetic compositions with excessively low viscosity are prone to pigment aggregation and / or caking at the bottom of the container. Therefore, cosmetic compositions with appropriate viscosity can maintain a desirable appearance for long periods of time during shelf display and storage, contributing to improved commercial value.

[0070] A cosmetic composition according to one embodiment comprises component e): a fatty acid ester nonionic surfactant with an HLB value of less than 8, and component e) includes a polyglycerin fatty acid ester surfactant and a sorbitan fatty acid ester surfactant.

[0071] The HLB value of component e) is less than 8, and may be 2 to 7, 2 to 4, 3 to 7, 3 to 6, or 4 to 6. The HLB value of component e) may also be 1 or more, 2 or more, or 3 or more.

[0072] Polyglycerin fatty acid ester surfactants include polyglycerin fatty acid monoesters such as diglyceryl stearate, diglyceryl oleate, diglyceryl isostearate (polyglyceryl-2 isostearate), tetraglyceryl stearate, and tetraglyceryl oleate; polyglycerin fatty acid diesters such as polyglyceryl-2 diisostearate and polyglyceryl-3 diisostearate; tetraglyceryl tristearate, decaglyceryl tristearate, and decaglyceryl trioleate. polyglycerol fatty acid triesters such as decaglyceryl pentastearate, decaglyceryl pentaoleate, decaglyceryl pentastearate, and decaglyceryl pentaoleate; and polyglycerol fatty acid polyesters such as polyglyceryl-6 polyricinoleate, polyglyceryl-10 polyricinoleate, polyglyceryl-5 polyricinoleate, polyglyceryl-4 polyricinoleate, and polyglyceryl-3 polyricinoleate.

[0073] The average degree of polymerization of polyglycerin in the polyglycerin fatty acid ester may be from 2 to 10. This further improves the emulsion stability of the cosmetic composition.

[0074] The polyglycerol fatty acid ester may be an esterification product of polyglycerol with a fatty acid having 8 to 24 carbon atoms, a fatty acid having 10 to 20 carbon atoms, or a fatty acid having 12 to 18 carbon atoms.
