Description

 Description Dibenzoylmethane derivatives, their production methods and applications

 TECHNICAL FIELD The present invention relates to a dibenzoylmethane derivative having excellent ultraviolet absorbing ability and high light stability and hardly causing a coloring reaction even in the presence of metal ion, a method for producing the same, an ultraviolet absorber containing the same, and a cosmetic. Background art

 Ultraviolet rays that reach the surface of the earth are classified into UV-B having a wavelength of 290 to 320 nm and UV-A having a wavelength of 320 to 400 nm. Ultraviolet light in the UV-A region has higher energy than UV-B region and is known to cause skin browning, burns, and aging. For example, Japanese Patent Application Laid-Open Publication Nos. 11-2822734, 11-1-2563, and 11-292748 disclose that dibenzoyl is used as a cosmetic for preventing ultraviolet rays. Just like the use of methane derivatives, cosmetics and the like containing UV absorbers such as dibenzoylmethane, benzophenone, and triazole have been developed and used to address such problems.

A dibenzoylmethane derivative, for example, 4-tert-butyl-14'-methoxydibenzoylmethane, is a light shielding agent described in Japanese Patent Application Laid-Open No. Effectively absorbs UV light in the A region. However, the dibenzoylmethane derivative is not only degraded and decomposed, but also colored due to interaction with metal ions. There is a problem. Particularly when used as cosmetics, the appearance is impaired by this coloring, which is not preferable.

 When preparing a light shielding agent containing the above-mentioned 4-tert-butynolene 4'-methoxydibenzoynolemethan, as in the case of using a sequestering agent, generally for the purpose of preventing coloring. Complexes represented by sodium ethylenediaminetetraacetate and sodium hydroxyethanesulfonate are used.

 However, it is not preferable to use a sequestering agent or the like in cosmetics or the like that directly touch the skin. Therefore, the development of a compound that effectively absorbs UV light in the UV-A region and has an excellent function of preventing coloring is desired. Purpose of the invention

 A first object of the present invention is to have a function of effectively absorbing ultraviolet rays in the UV-A region (having a large molecular extinction coefficient) and a function of preventing coloring due to interaction with metal ions. Another object of the present invention is to provide a novel dibenzoylmethane derivative excellent in water resistance and a method for producing the same.

 A second object of the present invention is to provide an ultraviolet absorber containing the novel dibenzoylmethane derivative utilizing the ultraviolet absorption ability and a cosmetic containing the same. Disclosure of the invention

UV—A dibenzoylmethane derivative that effectively absorbs UV light in the A region, such as 4-tert-butyl-1-4'-methoxydibenzoylmethane One possible cause is that the metal ion coordinates and binds to the lone pair of carbonyl groups. Therefore, as a result of intensive studies on the method of suppressing coloring by metal ions, it was found that compounds in which a substituent was introduced at the ortho-position to the carbonyl group bonded to the aromatic ring of the dibenzoylmethane derivative could suppress coloring by metal ions. And completed the present invention.

 In the first aspect of the present invention, general formula (1)

(In the formula, R ¹ is a group selected from the group consisting of a hydrogen atom, a linear or branched alkyl group and an alkoxy group, and R ² is a hydrogen atom, a linear or branched alkyl group and an alkoxy group. R ³ is a group selected from the group consisting of a hydrogen atom, a linear or branched alkyl group and an alkoxy group, and R ⁴ is a hydrogen atom or a hydrogen atom.

And a dibenzoylmethane derivative represented by the formula:

In the dibenzoylmethane derivative, steric hindrance due to either of R ² and R ⁵ not being a hydrogen atom is important in preventing coloring based on a reaction with a metal ion. In addition, when any one of R ³ , R ⁴ and R ⁶ is hydrogen, it is a preferable compound because it has excellent solubility when mixed with a cosmetic component. In addition to these conditions, a compound in which both R ³ and R ⁶ are hydrogen atoms is a particularly preferred compound because it has even better solubility when mixed with cosmetic ingredients. In the second aspect of the present invention, general formula (1)

(Wherein, R ¹ is a group selected from the group consisting of a hydrogen atom, a linear or branched alkyl group and an alkoxy group, and R ² is a hydrogen atom, a linear or branched alkyl group and an alkoxy group. R ³ is a group selected from the group consisting of a hydrogen atom, a linear or branched alkyl group and an alkoxy group, and R ⁴ is a hydrogen atom or a hydrogen atom. Is a group selected from the group consisting of a linear or branched alkyl group and an alkoxy group, and R ⁴ is an alkoxy group when R ¹ is a linear or branched alkyl group; When R ¹ is an alkoxy group, it is a linear or branched alkyl group, and R ⁵ is a hydrogen atom, a linear or branched alkyl group or an alkoxy group. R ⁶ is a group selected from the group consisting of a hydrogen atom, a linear or branched alkyl group and an alkoxy group, and ^one of R ¹ and R ⁴ , and R ² and R Any of ⁵ is selected from groups that are not hydrogen atoms. )
