External composition for skin or hair care

Abstract

Skin aging is caused by various causes other than aging, and photoaging due to ultraviolet rays is also known in recent years. Among ultraviolet rays, UVA causes a blackening phenomenon and promotes production of reactive oxygen species (ROS) through activation of NADPH oxygenase and the like. ROS causes photoaging of the skin such as causing DNA damage. In such a background, studies on components having an inhibitory effect on ROS production induced by ultraviolet rays have been advanced, and external preparation compositions for skin or hair care have been developed, but the effects thereof are not necessarily satisfactory.SOLUTION: To provide a new external preparation composition for skin or hair care, suppressing ROS production by NADPH oxidase activity inhibition and preventing photoaging by formulating trimethoxybenzylidene pentanedione.SELECTED DRAWING: Figure 1

Description

[Technical Field]

[0001] The present invention relates to a topical skin or hair care composition containing trimethoxybenzylidene pentanedione. Here, the topical skin or hair care composition refers to skin care cosmetics such as face washes, lotions, creams, and packs; makeup cosmetics such as foundations, lipsticks, and mascaras; hair care cosmetics such as shampoos, conditioners, hair styling agents, hair growth agents, hair colorants, and permanent wave agents; body care cosmetics such as body soaps, slimming agents, UV protection agents, bath agents, and antiperspirants; and fragrance cosmetics such as perfumes and colognes, including legal cosmetics, quasi-drugs, and pharmaceuticals. [Background technology]

[0002] Skin aging occurs due to various factors other than aging, and in recent years, photoaging caused by ultraviolet rays has also become known.

[0003] Among ultraviolet rays, UVB causes inflammation of the epidermis, while UVA not only causes darkening but also penetrates the dermis and produces reactive oxygen species (ROS), which cause DNA damage and contribute to photoaging of the skin. UVA activates NADPH oxygenase in cells, promoting the production of ROS.

[0004] To prevent damage caused by UV rays, it is common to apply sunscreen preparations containing UV protection agents to the skin to block UV rays. It is also thought that ingredients with antioxidant activity can be effective against photoaging caused by UVA rays.

[0005] As a means of preventing the production of ROS that causes DNA damage, Patent Document 1 discloses the effect of a vegetable oil containing an α-linolenic acid derivative as an active ingredient in suppressing the increase in ROS caused by UV irradiation, while Patent Document 2 discloses the effect of a topical composition containing γ-oryzanol in suppressing ROS production caused by UVA.

[0006] [Patent Document 1] Japanese Patent Application Publication No. 2019-202990 [Patent Document 2] Japanese Patent Application Publication No. 2020-180070 DISCLOSURE OF THE INVENTION [Problem to be solved by the invention]

[0007] Against this background, research has been conducted into ingredients that have the effect of suppressing UV-induced ROS production, and topical skin or hair care compositions have been developed, but the effects have not necessarily been satisfactory. [Means for solving the problem]

[0008] The present invention was made under the above circumstances, and provides a novel topical skin or hair care composition that suppresses ROS production by inhibiting NADPH oxidase activity and prevents photoaging by incorporating trimethoxybenzylidene pentanedione.

[0009] The present invention relates to a skin or hair care composition containing trimethoxybenzylidene pentanedione.

[0010] Claim 2 of the present invention is the external preparation composition for skin or hair according to claim 1, wherein the trimethoxybenzylidene pentanedione is contained in an amount of 0.01 to 5.0% by mass. [Effects of the Invention]

[0011] The trimethoxybenzylidene pentanedione of the present invention inhibits the activation of NADPH oxidase by UVA irradiation, thereby suppressing ROS production, thereby preventing photoaging caused by UV rays and maintaining youthful skin. [Brief explanation of the drawings]

[0012] [Figure 1] Figure 1 shows the inhibitory effect of the trimethoxybenzylidene pentanedione of the present invention on intracellular ROS production caused by UVA irradiation. It can be seen that when commercially available trimethoxybenzylidene pentanedione was added, the ROS level was lower than when it was not added. DETAILED DESCRIPTION OF THE INVENTION

[0013] The present invention will be described in detail below. The method for producing trimethoxybenzylidenepentanedione used in the present invention is not particularly limited, but a synthetic product is available as a commercial raw material "Synoxyl HSS" from Sytheon Ltd. in the United States.

[0014] The amount of trimethoxybenzylidene pentanedione of the present invention is 0.01 to 5.0% by mass, preferably 0.1 to 2.5% by mass, based on the total amount of the topical skin composition using the commercially available raw materials. When preparing a typical topical skin or hair care composition, if the amount is less than 0.01% by mass, the effect of suppressing ROS production and preventing photoaging is not achieved. Although it is possible to incorporate more than 2.5% by mass, up to 5.0% by mass, this is not preferred because the effect commensurate with the amount incorporated gradually saturates.

[0015] The effect of the topical skin or hair care composition of the present invention is to suppress UV-induced ROS production and prevent photoaging. Therefore, when the topical skin or hair care composition of the present invention is used in combination with an ingredient with antioxidant and UV protection effects, further photoaging protection effects can be expected.
