Description

[Technical Field]

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

[0002] The UV protection effect of sunscreen cosmetics is quantified by the SPF value, and the higher the UV protection effect, the higher the SPF value. There are products with a variety of SPFs on the market, but consumers tend to prefer products with a high SPF. UV protection agents that provide UV protection can be broadly divided into UV absorbers, such as ethylhexyl methoxycinnamate, and UV scattering agents, such as titanium dioxide, and a high concentration of these is required to achieve a high SPF.

[0003] However, a high content of UV absorbers can lead to stickiness and a poor feel when used. Furthermore, a high content of UV scattering agents can cause a rough, dry feeling. To solve these problems, incorporating an SPF improver that enhances the effectiveness of the UV protection agent can provide sufficient UV protection while reducing the amount of UV protection agent incorporated. For example, Patent Document 1 proposes a sunscreen cosmetic containing an inorganic UV protection agent consisting of a carboxylic acid-modified silicone, a vinyl polymer emulsion, a basic compound, and hydrophobic metal oxide fine particles, and describes that the SPF is improved by using the carboxylic acid-modified silicone and the vinyl polymer emulsion in combination.

[0004] Typical situations in which sunscreen cosmetics are used include outdoor summer sports, swimming in the sea, and other leisure activities. In these situations, sunscreen cosmetics applied to the skin must be water-resistant so that they will not be washed away by sweat, seawater, etc. To impart water resistance, many water-in-oil sunscreen cosmetics have been developed. For example, Patent Document 2 proposes a water-in-oil sunscreen cosmetic composed of polyhydroxystearic acid, a volatile hydrocarbon oil, a hydrophobized metal oxide, an organically modified clay mineral, and a nonionic surfactant.

[0005] Furthermore, among the aforementioned usage scenarios, it is also envisioned that sunscreen cosmetics will be applied to skin that is already wet with sweat, seawater, etc. Patent Document 3 proposes an oil-in-water skin cosmetic containing an oil, a hydrocarbon oil, isostearic acid, and a nonionic surfactant as a cosmetic that blends well even when applied to wet skin. However, water-in-oil sunscreen cosmetics such as those disclosed in Patent Document 2 tend to contain a large amount of oils that are poorly soluble in water or UV scattering agents whose particle surfaces have been hydrophobized, and therefore do not blend well when applied to wet skin.

[0006] Furthermore, with consumers becoming increasingly aware of skin care, sunscreen cosmetics are being sought that not only provide UV protection but also offer various other added values. For example, the sense of adhesion when applied to the skin is one in which the skin is coated and highly moisturizing. To achieve this sense of adhesion, Patent Document 4 proposes a water-in-oil sunscreen cosmetic that combines an organically modified clay mineral, a specific form of hydrophobic titanium oxide, oil, and water. Furthermore, to maintain this sense of adhesion, Patent Document 5 proposes an oil-in-water sunscreen cosmetic that contains an oil-soluble UV absorber, a liquid oil, a dextrin fatty acid ester, hydrophobic silica, and a water-soluble polymer having structural units derived from (meth)acrylic acid or sulfonic acid. However, water-in-oil sunscreen cosmetics have been insufficient in maintaining this sense of adhesion.

[0007] Therefore, there is a need for the development of a water-in-oil sunscreen cosmetic that has a high UV protection effect while reducing the amount of UV protection agent by using an SPF improver, that is easily absorbed even when applied to wet skin, that has an excellent adhesion feeling, and that has excellent durability of adhesion feeling.

[Means for solving the problem]

[0010] As a result of extensive research into solving the above-mentioned problems, the present inventors have found that a water-in-oil sunscreen cosmetic that can solve the above-mentioned problems can be obtained by incorporating a combination of at least one member selected from the group consisting of titanium oxide and zinc oxide, a divalent metal salt of a fatty acid having 12 to 18 carbon atoms, a dextrin fatty acid ester, and a silicone oil in amounts each within a specific range, and have thus completed the present invention.

Each component will be described below.

[0014] [(A) At least one selected from the group consisting of titanium oxide and zinc oxide] The at least one member selected from the group consisting of titanium oxide and zinc oxide (component (A)) used in the water-in-oil sunscreen cosmetic of the present invention is not particularly limited, and any oxide commonly used in the cosmetic field can be used. Component (A) corresponds to an ultraviolet protection agent.

[0015] In addition, titanium oxide or zinc oxide may be untreated or may be subjected to various surface treatments, but preferably is subjected to surface treatments that have excellent dispersibility.Surface treatment agents that can be used include, for example, inorganic minerals such as aluminum hydroxide and hydrated silica, silicones such as dimethicone and alkyl-modified silicone, alkoxysilanes such as octyltriethoxysilane, dextrin fatty acid esters such as dextrin palmitate, and fatty acids such as stearic acid.In addition, titanium oxide and zinc oxide may be in the form of fine particles, and preferably have an average primary particle size of 50 nm or less. The water-in-oil sunscreen cosmetic of the present invention may contain titanium oxide or zinc oxide as component (A) either singly or in combination, with a combination of two being preferred.

[0016] The content of the component (A) in the water-in-oil sunscreen cosmetic of the present invention is 1 to 30% by mass, preferably 3 to 25% by mass, and more preferably 5 to 20% by mass. If the content of component (A) is less than 1% by mass, the SPF and adhesion may decrease, and if the content of component (A) exceeds 30% by mass, the adhesion may decrease.

[0017] [(B) Divalent metal salt of fatty acid having 12 to 18 carbon atoms] Examples of divalent metal salts of fatty acids having 12 to 18 carbon atoms (component (B)) used in the water-in-oil sunscreen cosmetic of the present invention include zinc laurate, calcium laurate, magnesium laurate, zinc myristate, calcium myristate, magnesium myristate, zinc palmitate, calcium palmitate, magnesium palmitate, zinc stearate, calcium stearate, magnesium stearate, etc., with zinc stearate being preferred. Component (B) corresponds to an SPF improver.

[0018] The component (B) in the water-in-oil sunscreen cosmetic of the present invention is not particularly limited and any component commonly used in the cosmetics field can be used, but from the standpoints of SPF boost effect and adhesion, those with an average particle size of 1 to 50 μm are preferred. The water-in-oil sunscreen cosmetic of the present invention can contain, as component (B), one or a combination of two or more of zinc, calcium, or magnesium fatty acids having 12 to 18 carbon atoms. Furthermore, from the viewpoint of SPF-boosting effect, it is preferable that component (B) contains a combination of a divalent metal salt of a fatty acid having an average particle size of 1 to 5 μm and a divalent metal salt of a fatty acid having an average particle size of 10 to 50 μm. It is preferable that these two types of divalent metal salts of fatty acids with different average particle sizes are divalent metal salts of the same type of fatty acid. Of these, it is particularly preferable that component (B) contains a combination of zinc stearate having an average particle size of 1 to 5 μm and zinc stearate having an average particle size of 10 to 50 μm. In this specification, the average particle size is the average particle size (D50) measured using a laser scattering particle size distribution analyzer. The average particle size (D50) means the cumulative 50% particle size on a volume basis.

[0019] The content of the component (B) in the water-in-oil sunscreen cosmetic of the present invention is 0.1 to 5% by mass, preferably 0.2 to 4.5% by mass, and more preferably 0.3 to 3.5% by mass. If the content of component (B) is less than 0.1% by mass, the SPF boost effect may be reduced, and the feeling of adhesion and the durability of the feeling of adhesion may be poor. If the content of component (B) is more than 5% by mass, the ease of absorption into wet skin may be reduced.

[0020] [(C) Dextrin fatty acid ester] The dextrin fatty acid ester (component (C)) used in the water-in-oil sunscreen cosmetic of the present invention is an ester of dextrin or reduced dextrin with a higher fatty acid, and any ester commonly used in cosmetics can be used without any particular limitation. Furthermore, as the higher fatty acid used to obtain the dextrin fatty acid ester, it is preferable to use a saturated fatty acid having 8 to 22 carbon atoms. Specific examples of the dextrin fatty acid ester of the present invention include dextrin myristate, dextrin palmitate, dextrin stearate, dextrin oleate, and dextrin (palmitate / 2-ethylhexanoate), with dextrin palmitate being preferred. The content of the component (C) in the water-in-oil sunscreen cosmetic of the present invention is 0.1 to 5% by mass, preferably 0.2 to 4.5% by mass, and more preferably 0.3 to 3.5% by mass. If the content of component (C) is less than 0.1% by mass, the cosmetic may not blend well with wet skin, and if the content of component (C) is more than 5% by mass, the cosmetic may not adhere well to wet skin.

[0021] [(D) Silicone oil] The silicone oil (component (D)) used in the water-in-oil sunscreen cosmetic of the present invention can be any oil that is commonly used in cosmetics, without any particular limitations.

[0022] Examples of component (D) in the water-in-oil sunscreen cosmetic of the present invention include linear polysiloxanes, branched polysiloxanes, cyclic siloxanes, phenyl-modified silicones, polyether-modified silicones, higher fatty acid ester-modified silicones, higher alkoxy-modified silicones, fluorine-modified silicones, and crosslinked organopolysiloxanes, with linear polysiloxanes, branched polysiloxanes, and cyclic siloxanes being preferred, and linear polysiloxanes and cyclic siloxanes being more preferred.

[0023] Examples of linear polysiloxanes include dimethylpolysiloxane, examples of branched polysiloxanes include ethyltrisiloxane, methyltrimethicone, and tetrakis(trimethylsilyl)silane, and examples of cyclic siloxanes include octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane, and dodecamethylcyclohexasiloxane.

[0024] The component (D) in the water-in-oil sunscreen cosmetic of the present invention is preferably a low-viscosity silicone oil, where low viscosity means that the kinematic viscosity at 25°C is 20 cSt or less. Of these, component (D) is preferably a mixture of a first low-viscosity silicone oil having a kinematic viscosity at 25°C of less than 8 cSt and a second low-viscosity silicone oil having a kinematic viscosity at 25°C of 8 to 20 cSt.

[0025] The content of the component (D) in the water-in-oil sunscreen cosmetic of the present invention is 5% to 30% by mass, preferably 7% to 25% by mass, and more preferably 10% to 20% by mass. If the content of component (D) is less than 5% by mass, the compatibility with wet skin and the durability of the adhesive feeling may decrease, and if the content of component (D) is more than 30% by mass, the compatibility with wet skin may decrease. Furthermore, as described above, component (D) is preferably a mixture of a first low-viscosity silicone oil having a kinematic viscosity of less than 8 cSt at 25° C. and a second low-viscosity silicone oil having a kinematic viscosity of 8 to 20 cSt at 25° C. In this case, from the viewpoints of SPF boost effect, ease of blending into wet skin, and durability of adhesion, the mass ratio of the first low-viscosity silicone oil to the second low-viscosity silicone oil (first low-viscosity silicone oil / second low-viscosity silicone oil) is preferably 0.5 to 20, and more preferably 3 to 15.
