• the inventor first investigated the effect of the cosmetic formulation on SPF and usability (stickiness, etc.). As a result, the inventor found that in the case of two-phase separation systems consisting of an oil phase and an aqueous phase, and emulsion systems, not only was the SPF performance insufficient, but the usability was also unsatisfactory, whereas in the case of a single-phase system containing a non-aqueous volatile component such as ethanol, although the SPF performance was insufficient, the usability was satisfactory, and that there was room for improvement in such formulations.
• the subject of this disclosure is therefore to provide a single-phase UV care cosmetic composition containing a non-aqueous volatile component that not only provides UV protection when applied, but also provides excellent UV protection after splashing water or sweating, and is also easy to use.
• a single-phase UV care cosmetic composition comprising at least one dispersant selected from the group consisting of polyhydroxystearic acid, polyglycerol fatty acid esters, and polyglycerol-modified silicones, an ultraviolet absorbing agent, hydrophobic particles, and a non-aqueous volatile component.

• the single-phase UV care cosmetic composition disclosed herein contains an ultraviolet absorbing agent, hydrophobic particles, at least one dispersant selected from the group consisting of polyhydroxystearic acid, polyglycerin fatty acid ester, and polyglycerin-modified silicone, and a non-aqueous volatile component.
• the principle of action of the single-phase UV care cosmetic composition containing the non-aqueous volatile component of the present disclosure which not only has an excellent UV protection effect when applied, but also has an excellent UV protection effect after splashing water or sweating, and is also excellent in usability, is believed to be as follows.
• UV protection effect or “UV protection performance”
• UV protection effect after splashing water or sweating may be referred to as “water-resistant UV protection effect” or “water-resistant UV protection performance”.
• UV care cosmetics are typically used during the hot summer months, and so there is a tendency for them to be non-sticky and have a refreshing feel when used.
• Cosmetics based on emulsions or two-phase separation systems consisting of an oil phase and an aqueous phase generally contain a lot of water and take a long time to dry after application to the skin, making it difficult to achieve a refreshing feel when used.
• single-phase cosmetics that contain non-aqueous volatile components typically contain less water than the above formulations and contain a lot of easily volatile non-aqueous volatile components such as ethanol, making it easier to achieve a good feel when used.
• Non-aqueous volatile components in cosmetics such as ethanol
• hydrophobic and hydrophilic properties have hydrophobic and hydrophilic properties, and are therefore thought to be compatible with the UV absorbers contained in the cosmetics. Therefore, when such cosmetics are applied to the skin, for example, it was expected that the UV absorbers would spread evenly over the skin, improving the UV protection effect, but contrary to expectations, sufficient UV protection effect could not be achieved.
• the inventors have conducted various studies on the components to be incorporated into cosmetics, and have unexpectedly discovered that in the case of single-phase cosmetics containing non-aqueous volatile components, when hydrophobic particles and a specific dispersant are selected from the various components that can be incorporated into cosmetics and incorporated into the cosmetics, the UV protection effect upon application is improved, as well as the UV protection effect after splashing water or sweating.
• the incorporation of either hydrophobic particles or a specific dispersant into single-phase cosmetics containing non-aqueous volatile components did not result in improved UV protection performance, particularly after a water resistance test.
• the non-aqueous volatile component volatilizes, and non-volatile components such as UV absorbers remain in a film on the surface of the skin.
• the UV absorbers contained in the non-volatile components after the non-aqueous volatile components volatilize are arranged in a balanced and uniformly dispersed state on the surface of the skin due to the influence of the hydrophobic particles and dispersant, and it is believed that this improves the UV protection effect when the cosmetic is applied to the skin.
• a single-phase cosmetic containing a non-aqueous volatile component typically, a large amount of the non-aqueous volatile component volatilizes, but it is believed that the combined use of hydrophobic particles and dispersants is effective in uniformly dispersing the UV absorbers in the remaining film under such conditions where evaporation is likely to occur.
• Dispersants used in cosmetics containing hydrophobic particles are typically agents used to disperse hydrophobic particles.
• the surface of hydrophobic particles is generally not uniform when viewed microscopically, and some parts are thought to be hydrophilic (for example, some parts of hydrophobized particles are not hydrophobized and the hydrophilic parts are exposed).
• the specific dispersant used in this disclosure can disperse hydrophobic particles while covering or filling such hydrophilic parts in a single-phase system containing non-aqueous volatile components. It is believed that hydrophobic particles with a reduced proportion of hydrophilic parts are applied uniformly to the skin surface, which makes it easier to repel water and improves water resistance, thereby improving the UV protection effect after water resistance evaluation.
• single phase refers to a single phase in which the continuous phase is substantially free of emulsified oil particles and is substantially composed of a non-aqueous volatile component, or a non-aqueous volatile component and an oil component that is compatible with said component. Therefore, in the present disclosure, a “single phase” may be a phase that contains any insoluble solid, such as hydrophobic particles.
• a cosmetic it is permissible for a cosmetic to contain, for example, a small amount of water or emulsified particles, or a small amount of oil component that is incompatible with the non-aqueous volatile component (for example, an oil component that is solvated (solubilized) with alcohol, etc.), to the extent that it does not affect the effects of the present disclosure.
• a cosmetic it is permissible for a cosmetic to contain, for example, a small amount of water or emulsified particles, or a small amount of oil component that is incompatible with the non-aqueous volatile component (for example, an oil component that is solvated (solubilized) with alcohol, etc.), to the extent that it does not affect the effects of the present disclosure.

• UV absorbent there are no particular limitations on the UV absorbent, and for example, an oil-based UV absorbent can be used.
