Abstract

PROBLEM TO BE SOLVED: To obtain a safe ultraviolet ray absorber excellent in UV-A and UV B absorbing actions without any irritation to the skin. SOLUTION: This ultraviolet ray absorber contains a pentadienoyl derivative of the formula (R<1> and R<2> are each H, OH, a lower alkoxy, a lower alkyl, a lower alkylcarbonyloxy or a halogen; R is a lower alkoxy, amino, a mono- or a di-lower alkyl-substituted amino or an amino acid residue) and its salt as active ingredients. The resultant ultraviolet ray absorber in an amount of 0.1-20wt.% is blended to afford a cosmetic such as a foundation, a cream, a milky lotion, a skin lotion, an antisuntan product, a hairdressing, a lotion or a hair treatment. When the ultraviolet ray absorber is applied, the occurrence of an erythema and pigmentation caused by ultraviolet rays are effectively suppressed.

2. Description of the Related Art Ultraviolet rays range from 400 to 320 depending on the wavelength of action.
Long wavelength UV (UV-A) of 320 nm, medium wavelength UV of 320 to 290 nm (U
VB) and short wavelength ultraviolet rays (UV-C) of 290 nm or less. Of these, UV-A and UV-B are known to cause harmful effects on human skin, except for UV-C, which is absorbed in the ozone layer and does not reach the ground. That is, chronic UV-B irradiation forms erythema and blisters, promotes melanogenesis, and causes pigmentation. On the other hand, UV-A has an action called immediate blackening that blackens the skin immediately after its irradiation, and unlike UV-B, its energy reaches the dermis and It causes a change in elastic fibers. The action of both UV-A and UV-B is
It is known to promote the generation of spots, wrinkles, freckles, and aging of the skin. Many compounds have been developed and are known so far for UV-B absorbers.
The UV-A absorption capacity is very low, and UV-A absorbers have been developed to compensate for it. Furthermore, by using a UV-A absorber and a UV-B absorber together, UV rays in both regions can be absorbed. UV absorbers that absorb light are also being developed.

However, under the condition of being exposed to sunlight, the presence of two or more active ingredients causes the decomposition of compounds by photoreaction, the influence of reaction products on the skin, and inevitably the drug. Since the total amount of the drug is increased, the stability and safety of the drug itself may be a problem. Therefore, it is desirable that one agent can absorb ultraviolet rays in a wide range, and ultraviolet absorbers having a wide absorption range have been developed.

Test Example 2 (Inhibition of melanocyte production by UV-B ultraviolet rays) Five C57BL / 6 mice were treated as one group, 10 μl of the test solution shown below was applied to the right auricle, and ethanol was applied to the left auricle. Only the same amount was applied. Similarly, the right auricle was covered with aluminum foil and the left auricle was left untreated as a UV cut group. Next, the FL20SE lamp manufactured by Toshiba was used as a light source, the auricle was placed directly under the light source, and irradiation was performed at 0.07 J / cm 2 (33 μW / cm 2 for 20 seconds). The application of the sample to the auricle of the mouse was performed once a day, and the irradiation of ultraviolet rays was once after the application and was repeated continuously for 3 days. Then, after left for 7 days, the left and right auricles were collected, and subsequently treated with NaBr to separate the epidermis. The epidermis was stained with Dopa to prepare a tissue sample, and the number of melanocytes was counted under a microscope. The test solution was 0.1 W / V% in a solvent composed of castor oil: ethanol = 1: 2,
Inventive product 5- (4-hydroxy-3-methoxyphenyl) -2E, 4E-pentadienoic acid obtained in Reference Example 1 at a ratio of 0.5 W / V% and 1.0 W / V%, and a comparative compound. 2- (2-benzotriazole)-
