Definitions
- the present invention relates to cosmetic compositions.
- UVB region wavelength 290-320 nm
- UVA region wavelength 320-400 nm
- UVA region wavelength 320-400 nm
- P-2-ethylhexyl p-methoxycinnamate is commonly used as a UV absorber in conventional UV protection cosmetics.
- 2-Ethylhexyl p-methoxycinnamate has the effect of absorbing ultraviolet rays in the UVB region, but there is a demand for an ultraviolet absorber having a better ability to absorb ultraviolet rays in the UVA region.
- the ultraviolet absorber disclosed in Patent Document 1 has the ability to absorb both the UVA region and the UVB region, has an ultraviolet suppression effect in a wide range of wavelengths, and with the passage of time of ultraviolet irradiation, UVA It is said to have a property that has not been seen in the past, such as an increase in the ability to absorb ultraviolet rays in the UVB region.
- UV absorber of US Pat. (wherein —OA represents an alkoxy group) as an active ingredient.
- the present invention is intended to improve the above circumstances, and the object thereof is to provide a cosmetic composition with further improved ultraviolet absorbing ability in the entire UVA and UVB regions.
- ⁇ Aspect 1> containing the following components (i) to (iii) and an oil capable of at least partially dissolving said component (i), (i) a compound I having the structure of formula (I): (Wherein, -OA represents an alkoxy group) (ii) UV scattering agent particles, and (iii) a dispersant,
- the content of the ultraviolet scattering agent particles is more than 7.0% by mass, and the dispersant is selected from the group consisting of polyhydroxystearic acid, isostearic acid, polyglyceryl-based dispersants, and sorbitan-based dispersants comprising at least one dispersing agent; cosmetic composition.
- ⁇ Aspect 6> A composition according to any one of aspects 1-5, wherein the oil comprises a polar oil.
- ⁇ Aspect 7> The composition according to any one of aspects 1 to 6, which is an oil-in-water cosmetic.
- ⁇ Aspect 8> The composition according to any one of aspects 1 to 6, which is a water-in-oil type cosmetic.
- ⁇ Aspect 9> The composition according to any one of aspects 1 to 6, which is an oily cosmetic.
- the cosmetic composition of the present invention (hereinafter also simply referred to as “the composition of the present invention”) is containing the following components (i) to (iii) and an oil capable of at least partially dissolving said component (i), (i) a compound I having the structure of formula (I): (Wherein, -OA represents an alkoxy group) (ii) UV scattering agent particles, and (iii) a dispersant,
- the content of the ultraviolet scattering agent particles is more than 7.0% by mass
- the dispersant is at least one selected from the group consisting of polyhydroxystearic acid, isostearic acid, polyglyceryl-based dispersants, and sorbitan-based dispersants. containing one dispersant, It is a cosmetic composition.
- the present inventors have unexpectedly found that when a specific dispersant is contained and the amount of UV scattering agent particles in the cosmetic is relatively large (for example, when it exceeds 7.0% by mass), , by using the compound I having the structure of the above formula (I) as an ultraviolet absorber instead of a conventional ultraviolet absorber, the integrated value of absorbance at 290 to 400 nm (that is, ultraviolet absorption in the entire UVA and UVB regions ability) was found to be greatly improved.
- Compound I > Compound I according to the invention has the structure of formula (I): (Wherein, -OA represents an alkoxy group)
- —OA represents an alkoxy group, and more specifically includes, but is not limited to, a methoxy group, an ethoxy group, or the like.
- compound I may have the same structure as the compound represented by general formula I disclosed in Patent Document 1.
- the compound I is at least partially dissolved, particularly 50% by mass or more is dissolved, more particularly 90% by mass. % is in solution, even more in particular 99% by weight or more is in solution, most especially 100% by weight is in solution.
- the content of compound I is not particularly limited. 0.5% by mass or more, 1.0% by mass or more, 1.5% by mass or more, 2.0% by mass or more, 2.5% by mass or more, 3.0% by mass or more, 3.5% by mass or more, 4 7.0% by mass or more, 4.5% by mass or more, 5.0% by mass or more, 5.5% by mass or more, 6.0% by mass or more, 6.5% by mass or more, 7.0% by mass or more; 5% by mass or more, 8.0% by mass or more, 8.5% by mass or more, 9.0% by mass or more, 9.5% by mass or more, or 10% by mass or more, and 50% by mass or less, It may be 40% by mass or less, 30% by mass or less, 20% by mass or less, 10% by mass or less, 8.0% by mass or less, 5.0% by mass or less, or 2.0% by mass or less.
- UV scattering agent particles By including the ultraviolet scattering agent particles in the composition of the present invention, the ultraviolet protection effect can be enhanced.
- the ultraviolet scattering agent particles are not particularly limited, and may be, for example, at least one kind of metal oxide particles selected from the group consisting of titanium oxide, zinc oxide, iron oxide, and cerium oxide.
- the ultraviolet scattering agent particles may be hydrophobized.
