Definitions
- the present invention relates to an ultraviolet protection compound and an ultraviolet protection agent containing the compound as an active ingredient.
- UV protection agents used in this type of cosmetics are roughly classified into organic UV protection agents and inorganic UV scattering agents.
- Organic UV protection agents have conjugated double bonds in the molecule, and these molecules absorb the light energy of ultraviolet light and convert it into another form of energy, such as heat energy.
- the wavelength of the ultraviolet light at which absorption is maximum (maximum absorption wavelength) is different. Therefore, organic UV protection agents are different from UVB absorbers (maximum absorption wavelength: 280 to 32 O nm), which absorb ultraviolet light on the relatively short wavelength side due to the difference in the absorption region of the ultraviolet light to be absorbed.
- UVA absorbers maximum absorption wavelength: 320 to 400 nm that absorb ultraviolet rays on the relatively long wavelength side.
- inorganic ultraviolet scattering agents are metal oxides represented by titanium dioxide, and scatter ultraviolet light with a high refractive index.
- inorganic ultraviolet scattering agents represented by titanium dioxide are generally white or pale yellow, and have a strong effect of concealing the surface of the applied material. Therefore, for example, when applying sunscreen cream containing an inorganic ultraviolet scattering agent to the skin to prevent sunburn, the skin becomes an unnatural skin color with a white tinge. Therefore, for example, if one wants to prevent sunburn, but wants to avoid having an unnatural skin color with a white tint, it is difficult to use only a large amount of the inorganic ultraviolet scattering agent. .
- organic UV protection agents are generally colorless or only slightly colored and have no or negligible effect on the surface of the coating. small.
- an organic UV protection agent or use an organic UV protection agent. It is preferable to use a mixture of the agent and an inorganic ultraviolet scattering agent at a suitable mixing ratio.
- Organic UV protective agents also have the advantage that by varying their molecular structure, the UV protective effect can be varied according to the intended use.
- UVA absorbent p-methoxycinnyl-2-ethylhexyl is commonly used as the UVA absorbent, and 4-tert-butyl-4'-methoxydibenzoylmethyl is generally used as the UVA absorbent.
- UV protection agents generally have high skin irritation and acute toxicity. Since UV protection agents are often applied to the skin over a wide area, it is desirable that skin irritation and acute toxicity be as low as possible. Also, in view of the recent increase in the amount of ultraviolet rays from the sun, it is desired to further improve the ultraviolet protection performance of the ultraviolet protective agent. In addition, it is also important that UV protection agents have a high resistance to degradation by light and heat, since they are exposed to direct sunlight for a long time after being applied to the skin.
- UV protection agents do not yet have sufficient performance as UV protection agents. Therefore, it has low toxicity to living organisms (for example, skin irritation and acute toxicity), high safety, strong absorption in UVB and UVA regions, and high resistance to degradation by light and heat.
- New compounds There is a strong demand for the development of a novel UV protection agent containing, as an active ingredient, a compound having a UV protection effect and a compound having the UV protection effect (including the novel compound).
- the present inventors have conducted intensive studies to solve the above-mentioned problems of the prior art, and as a result, as compared with known compounds having an ultraviolet protection effect, they have lower toxicity to living organisms and higher safety, and have an ultraviolet protection effect. Found a new compound having the same or larger value, and completed the present invention.

- the UV protective agent of the present invention contains, in addition to the compound represented by the formula I ′ as an active ingredient, other compounds, mixtures, and additional materials commonly used in the field of UV protective agents in a desired mixing ratio. obtain.
- the compound is a liquid crystal nematic eutectic mixture having electro-optical properties (Japanese Patent Application Laid-Open No. 57-125281) or a liquid crystal composition (Japanese Patent Application Laid-Open No. 58-157840). Is a compound that constitutes However, there is no description that the compound has an ultraviolet protection effect or that it can be used as an ultraviolet protection agent.
- 2-Methyl-5-ditropanol 54 mg, 3.53 mmol was placed in a 5 OmL eggplant-shaped flask, and after purging with argon, dichloroethane (23 mL) was added, followed by cooling with ice while stirring. To this flask was added tritylamine (0.59 mL, 4.24 t, 1.2 eq), and cinnamo iruku mouth lid (883 mg, 5.3 t, ol, 1.5 eq, A solution of dichloroethane (5 mL) in toluene (75%) was added dropwise over 5 minutes.
- Example 7 Inhibitory effect on UV irradiation of guinea pig skin
- Each of the compounds of the present invention and commercially available 2-ethylhexyl p-methoxycinnamate used as a positive control were mixed with an ointment base (Plastibase) to give 2.5% (mass% of active ingredient). And 5% ointment were prepared.
- the abdomen of male Hartley guinea pigs aged 6 to 10 weeks after birth was shaved with an electric barrier the day before the test and further shaved with an electric shaver.
- the test animals were anesthetized by intraperitoneal administration of sodium pentovalpital (30 mg / kg), and the base, 2.5% ointment and 5% ointment were applied to the shaved abdomen from the head side.
