Description

Technical Field

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

[0002] Ultraviolet rays are a major cause of skin aging, leading to the appearance of skin blemishes; such as scars, wrinkles, and freckles. It is desirable that daily-use cosmetics (such as foundations) prevent damage to the skin by ultraviolet rays to prevent and slow down skin aging. Known cosmetic compositions designed to resist ultraviolet rays include cosmetic compositions containing inorganic UV blockers (Korean Patent Application No. 1020160107064, International Patent Publication No. WO2019 / 98805).

[0003] For cosmetics, it is generally also preferred to have a high makeup effect, including a high covering effect, a long-lasting effect, and high stability. Summary of the Invention

[0004] Technical Problem

[0005] However, when increasing the amount of an ultraviolet ray scattering agent or an ultraviolet ray absorber in a cosmetic to improve its ultraviolet ray resistance effect, a powdery feeling of the ultraviolet ray scattering agent is brought about, and a sticky feeling is generated due to the ultraviolet ray absorber, so there are problems in terms of the skin makeup. Ultraviolet ray scattering agents and ultraviolet ray absorbers also produce undesirable results in terms of the makeup effect and stability.

[0006] An object of the present invention is to provide a cosmetic that can exhibit a high covering effect, a comfortable skin makeup, a long-lasting effect, and robust stability when containing an ultraviolet ray scattering agent or an ultraviolet ray absorber.

[0007] Means for Solving the Problem

[0008] The present invention provides a liquid water-in-oil emulsion cosmetic composition, wherein the cosmetic composition contains: 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, and the component e) contains a polyglycerol fatty acid ester surfactant and a sorbitan fatty acid ester surfactant.

[0009] One of the characteristics of the cosmetic composition is that it contains both a polyglycerol fatty acid ester surfactant and a sorbitan fatty acid ester surfactant as component e).

[0040] The cosmetic composition according to one embodiment comprises component a): a non-volatile liquid oil.

[0041] The non-volatile liquid oil is a non-volatile oil component that is liquid at normal temperature (in the range of 15 to 25 °C) and normal pressure (1 atmosphere). More specifically, the non-volatile liquid oil is an oil component having a mass loss value of less than 4% by mass (Equation (1)) after drying for 60 minutes at a temperature of 33 °C and a humidity of 55% according to the following scheme.

[0042] Component a) can be, for example, a non-volatile hydrocarbon oil, a higher alcohol, an ester oil, an ether oil, or a vegetable oil.

[0043] Examples of the non-volatile hydrocarbon oil include squalane, liquid paraffin, polybutene, polyisobutene, hydrogenated polyisobutene, hydrogenated polydecene, and olefin oligomers.

[0044] The higher alcohol is an aliphatic monohydric alcohol having 6 or more carbon atoms, preferably an aliphatic monohydric alcohol having 12 to 28 carbon atoms. Examples of the higher alcohol include octanol, dodecanol, oleyl alcohol, octyldodecanol, hexyl decanol, isostearyl alcohol, and decyltetradecanol.

[0045] Ester oils are carboxylic acid esters that are liquid and do not vaporize under normal temperature and pressure (e.g., 25 °C, 1 atmosphere), preferably alkyl carboxylic acid esters, where the carboxylic acid or alcohol of the ester has 8 to 18 carbon atoms. Examples of ester oils include propylene glycol fatty acid esters such as propylene glycol dioctanoate and propylene glycol didecanoate; fatty acid alkyl esters such as isopentyl laurate, hexyl laurate, ethylhexyl palmitate, isopropyl myristate, 2-octyldodecyl myristate, cetyl 2-ethylhexanoate, isononyl isononanoate, and isotridecyl isononanoate; carbonate esters such as dioctyl carbonate; tri- or higher fatty acid esters of polyglycerin such as polyglycerin-2 triisostearate, polyglycerin-2 tetraisostearate, and polyglycerin-10 decaisostearate; triglyceride fatty acid esters (also known as triglyceride oils) such as tri-2-ethylhexanoin, behenin, caprylic / capric triglyceride, and triheptanoin; benzoic acid derivatives such as diisostearyl malate and alkyl (C12-15) benzoate; salicylic acid derivatives such as homosalate and ethylhexyl salicylate; alkyl esters such as coco-caprylate / caprate and coco-caprylate; cinnamic acid derivatives such as octyl methoxycinnamate, isopropyl methoxycinnamate, isopentyl methoxycinnamate, cinnoxate, DEA methoxycinnamate, diisopropyl methylcinnamate, glyceryl ethylhexanoate-dimethoxycinnamate, and di-(2-ethylhexyl)-4'-methoxybenzyl malonate; and β,β-diphenylacrylate derivatives such as octocrylene.

[0048] Among the above non-volatile liquid oils, ethylhexyl salicylate, octyl methoxycinnamate, homosalate, and octocrylene function as oil-soluble organic UV filters. Specifically, 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 by itself to help prevent ultraviolet rays from reaching the skin.

[0052] When phenylbenzimidazole sulfonic acid is used as a water-soluble UV filter, for example, neutralization is necessary. Other substances other than phenylbenzimidazole sulfonic acid known to require neutralization are also preferably neutralized before use. Neutralization can be carried out by a conventional method, by mixing a neutralizing agent such that the pH of the liquid mixture of phenylbenzimidazole sulfonic acid and the neutralizing agent is 6.0 to 8.0 at room temperature. Neutralizing agents include sodium hydroxide, potassium hydroxide, triethanolamine, tromethamine and arginine.

If the content of component b) is 0.10% by mass or more, a higher UV protection effect will be exhibited, and as the content of component b) increases (at least up to 10% by mass), a further higher UV protection effect tends to be exhibited. If the content of component b) is 10% by mass or less, the refreshing feeling and skin compatibility when it is applied to the skin can be further improved, and as the content of component b) decreases (at least down to 0.10% by mass), the refreshing feeling and skin compatibility tend to further increase.

[0054] The cosmetic composition according to one embodiment further comprises component c): an inorganic UV filter. The inorganic UV filter is significantly different from pigments that do not have UV protection properties and pigments whose main purpose is for coloring.

[0068] The term "volatile oil" refers to an oil that loses 4% or more by mass after drying for 60 minutes at a temperature of 33 °C and a humidity of 55% according to the following protocol: Weigh 20 mg of the oil to be studied on a 5 cm × 5 cm polymethyl methacrylate (PMMA) plate using a micropipette and a precision balance. Spread the oil to be studied over the entire plate with a finger. Then place the plate in a fume hood with temperature and humidity controlled at 33 °C and 55% humidity. Conduct 3 tests for each oil. Measure the mass loss during drying after 60 minutes. The mass loss is expressed according to the following formula (1):

[0069] Formula (1)

[0070] [Mathematical formula 1]

[0071]

[0072] In formula (1), mtx represents the mass of the plate measured 60 minutes after the start of drying, and mt0 represents the mass of the plate measured before drying. The volatile hydrocarbon oil can also be considered to be a liquid at normal temperature and pressure and is an oily component that gradually evaporates.

[0073] Component d) may further include a volatile straight-chain hydrocarbon oil or a volatile branched-chain hydrocarbon oil. Component d) may further include a volatile hydrocarbon oil having 8 to 19 carbon atoms. Component d) may be selected from the group consisting of branched C8-C16 alkanes (such as isoparaffins, isododecane, isodecane, and isohexadecane), straight-chain C8-C16 alkanes (such as nonane, decane, undecane, dodecane, tridecane, pentadecane, and hexadecane), a mixture of C9-C17 alkanes, a mixture of C10-C14 alkanes, a mixture of undecane and tridecane, a mixture of C15-C19 alkanes, a mixture of C9-C12 alkanes, a mixture of C12-C14 alkanes, and a combination of n-dodecane and n-tetradecane. Component d) may further include a volatile straight-chain or branched-chain hydrocarbon having 9 to 12 carbon atoms, a volatile straight-chain or branched-chain hydrocarbon having 13 to 15 carbon atoms, or a mixture thereof.

[0074] An oil having a mass loss value of 4% or more but not exceeding 30% by mass can be called a "slightly volatile oil". Slightly volatile oils include isohexadecane, pentadecane, hexadecane, C13-15 alkanes, and C15-19 alkanes. If the cosmetic composition contains a slightly volatile oil, the smoothness of the cosmetic composition tends to improve.

[0075] An oil having a mass loss value of 30% or more but not exceeding 80% by mass can be called a "moderately volatile oil". Moderately volatile oils include undecane, dodecane, tridecane, and C9-12 alkanes (straight-chain). If the cosmetic composition contains a moderately volatile oil, the balance between the smoothness and skin adhesion of the cosmetic composition can be improved.

[0076] An oil having a mass loss value of 80% or more by mass can be called a "highly volatile oil". Highly volatile oils include nonane, decane, isododecane, and C9-12 alkanes (branched-chain). If the cosmetic composition contains a highly volatile oil, the skin adhesion of the cosmetic composition tends to improve.

[0077] Based on the total amount of the cosmetic composition, the content of component d) can be 1.0 to 30% by mass, 2.0 to 30% by mass, 3.0 to 30% by mass, 4.0 to 30% by mass, 5.0 to 30% by mass, 1.0 to 25% by mass, 2.0 to 25% by mass, 3.0 to 25% by mass, 4.0 to 25% by mass, 5.0 to 25% by mass, 1.0 to 20% by mass, 2.0 to 20% by mass, 3.0 to 20% by mass, 4.0 to 20% by mass, 5.0 to 20% by mass, 1.0 to 15% by mass, 2.0 to 15% by mass, 3.0 to 15% by mass, 4.0 to 15% by mass, 5.0 to 15% by mass, 1.0 to 13% by mass, 2.0 to 13% by mass, 3.0 to 13% by mass, 4.0 to 13% by mass, or 5.0 to 13% by mass. If the content of component d) is 1.0% by mass or more, the low-level viscosity of the cosmetic composition can be maintained, thereby allowing the formation of a thinner cosmetic layer, and as the content of component d) increases (up to at least 30% by mass), it tends to allow the formation of a thinner cosmetic layer. If the content of component d) is 30% by mass or less, it is easier to maintain the appropriate viscosity of the cosmetic composition and further increase the product stability, and as the content of component d) decreases (down to at least 1.0% by mass), it tends to allow a further increase in product stability. A cosmetic composition with too low viscosity tends to cause the aggregation and / or caking of pigments at the bottom of the container. Therefore, a cosmetic composition with an appropriate viscosity can maintain an ideal appearance form for a long time during the display on the product shelf or during storage, thereby contributing to an increase in commercial value.

[0078] The cosmetic composition according to one embodiment contains component e): a fatty acid ester nonionic surfactant with an HLB value of less than 8, wherein component e) contains a polyglycerol fatty acid ester surfactant and a sorbitan fatty acid ester surfactant.

[0079] The HLB value of component e) is less than 8, and can be 2 to 7, preferably 2 to 6, more preferably 3 to 6, 3 to 5, or 4 to 6. The HLB value of component e) can also be 1 or more, 2 or more, or 3 or more.

[0080] The polyglycerol fatty acid ester surfactants include monoglycerol polyglycerol fatty acid esters such as polyglycerol-2 stearate, polyglycerol-2 oleate, polyglycerol-2 isostearate, polyglycerol-4 stearate, and polyglycerol-4 oleate; diglycerol polyglycerol fatty acid esters such as polyglycerol-2 diisostearate and polyglycerol-3 diisostearate; triglycerol polyglycerol fatty acid esters such as polyglycerol-4 tristearate, polyglycerol-10 tristearate, polyglycerol-10 trioleate; pentaglycerol polyglycerol fatty acid esters such as polyglycerol-10 pentastearate, polyglycerol-10 pentaoleate, polyglycerol-10 pentahydroxystearate; and polyester polyglycerol fatty acid esters such as polyglycerol-6 polyricinoleate, polyglycerol-10 polyricinoleate, polyglycerol-5 polyricinoleate, polyglycerol-4 polyricinoleate, and polyglycerol-3 polyricinoleate.

[0081] The average degree of polymerization of the polyglycerol in the polyglycerol fatty acid ester can be from 2 to 10. This will further improve the emulsion stability of the cosmetic composition.

[0082] The polyglycerol fatty acid ester can be an ester compound of polyglycerol and 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. This will further improve the emulsion stability of the cosmetic composition.

[0083] The sorbitan fatty acid ester surfactants can be sorbitan palmitate, sorbitan stearate, sorbitan sesquisterate, sorbitan trioleate, sorbitan isostearate, sorbitan sesquiisostearate, sorbitan oleate, or sorbitan sesquioleate.

If the content of component e) is 1.0% by mass or more, a more long-lasting makeup effect will be obtained, and a further more long-lasting makeup effect tends to be obtained as the content of component e) increases (at least up to 20% by mass). If the content of component e) is 20% by mass or less, a more uniform skin makeup will be more easily obtained when the cosmetic composition is applied to the skin, and a more uniform skin makeup will be more easily obtained as the content of component e) decreases (at least down to 1.0% by mass).

If the cosmetic composition includes a gelling agent, due to the interaction between the components or colloidal particles dissolved or dispersed in the cosmetic composition, a three-dimensional higher-order structure (e.g., a network three-dimensional structure) will be formed. As a result, the fluidity of the composition will tend to be lower and the viscosity will tend to increase. In other words, the gelling agent can act as a thickening agent.

[0173] Deterioration in the emulsified state: Even when shaken by hand 10 times, the oil phase and the water phase still remain separated.

[0174] Powder aggregation: Even when shaken by hand 10 times, there is still inhomogeneous dispersion of the pigment and uneven color.

[0175] The results are summarized in Tables 5 and 6 below. For all evaluations, compositions that received an evaluation of "A to C" or "a" are considered acceptable for the purposes of the present invention. Compositions that received at least one evaluation of "D to F" or "f" are considered unacceptable for the purposes of the present invention. As shown in Table 5 below, Examples 6 and 7 received an "A" or "a" in all evaluations and had the best effects.
