Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to an anti-aging cosmetic having an effect of suppressing skin aging.

[0002]

2. Description of the Related Art Skin aging characterized by wrinkle and tarmi is due to a decrease in collagen production of fibroblasts, a decrease in hyaluronic acid synthesis, an increase in collagenase activity due to ultraviolet rays, and a damage due to active oxygen generated from ultraviolet rays and the environment. Is believed to be. Retinol, retinoic acid, and the like are used to improve such wrinkles and tarmi. In addition, collagen, plant extracts and the like having a collagen production promoting action are also used.

[0003]

Retinol, retinoic acid and the like have been used to improve wrinkles and tarmi, but they also have strong side effects. In addition, collagen, plant extract, etc. having hyaluronic acid synthesis accelerating action are used. However, since each has only a weak effect, when they are individually mixed in cosmetics, sufficient anti-aging, that is, wrinkles.・ The effect of improving tarmi was not obtained.

[0004] Therefore, it has been desired to develop a highly safe cosmetic composition having no side effect with respect to an excellent effect of improving wrinkles and tarmi.

[0005]

[Means for Solving the Problems] Due to such circumstances,
As a result of intensive studies aimed at improving skin aging, the present inventors have found that one or more selected from plant extracts having a hyaluronic acid synthesis-accelerating effect and the content of fish-derived collagen suppress excellent skin aging. It has been found that it has the effect of, and has completed the present invention.

That is, the present invention provides the following components (A) and (B); (A) one or more selected from plant extracts having a hyaluronic acid synthesis promoting action, and (B) skin containing fish-derived collagen. Is an anti-aging cosmetic.

The plant extract of the component (A) used in the present invention is not particularly limited as long as it has a hyaluronic acid synthesis accelerating action, but is preferably Kidachi aloe, lavender, thyme, cabbage / legi, keraba, holy basil, Marjoram, Rumpuyan, Laemjan and so on.

The solvent to be extracted is, for example, water, lower alcohols (methanol, ethanol, 1-propanol, 2-propanol, 1-butanol, 2-butanol, etc.), liquid polyhydric alcohol (glycerin, propylene glycol, 1). , 3-butylene glycol, etc.), ketones (acetone, methyl ethyl ketone, etc.), acetonitrile, esters (ethyl acetate, butyl acetate, etc.), hydrocarbons (hexane, heptane, liquid paraffin, etc.), ethers (ethyl ether, propyl, etc.) Ether, tetrahydrofuran, etc.). Water, lower alcohols and liquid polyhydric alcohols are preferable, and water, ethanol, propylene glycol and 1,3-butylene glycol are particularly preferable. These solvents may be used alone or in combination of two or more.

The extracted solutions may be used as they are, or if necessary, they may be subjected to treatments such as concentration, dilution and filtration, and decolorization and deodorization treatment with activated carbon before use. Furthermore, the extracted solution may be concentrated to dryness, spray-dried, freeze-dried and the like and used as a dried product.

The amount of component (A) used in the present invention is not particularly limited, but is preferably 0.0001% by weight in terms of solid content based on the total amount of the cosmetic of the present invention.
The above is preferable, and 0.0005 to 10% by weight is more preferable. If it is less than 0.0001% by weight, it is difficult to exert a sufficient effect. When it is blended in an amount of more than 10% by weight, the effect is not enhanced so much and it is uneconomical. Regarding the method of addition, it may be added in advance or may be added during the production, and may be appropriately selected in consideration of workability.

Among these, the component (A) is used alone or in combination of two or more in the cosmetic of the present invention.

The fish-derived collagen which is the component (B) used in the present invention is not particularly limited, but for example, skins such as salmon, goldfish, codfish, flounder and the like or a floating bag are washed, degreased, acid filtered, treated with an enzyme, After means such as salt folding, dialysis, and heat treatment,
The thing obtained after extracting a solubilized collagen component is mentioned. These are generally commercially available as a fish-derived collagen solution and used as a raw material for cosmetics. It may or may not be atherogenic.

The solution may be used as it is, and if necessary,
Concentration, dilution, filtration, etc. and decolorization with activated carbon, etc.
It may be used after being deodorized. Furthermore, the extracted solution may be concentrated to dryness, spray-dried, freeze-dried and the like and used as a dried product.

The blending amount of the component (B) used in the present invention is not particularly limited, but is preferably 0.0001% by weight or more in terms of solid content based on the total amount of the cosmetic of the present invention, and more preferably. Is preferably 0.00001 to 10% by weight. If it is less than 0.0001% by weight, it is difficult to exert a sufficient effect. When it is blended in an amount of more than 10% by weight, the effect is not enhanced so much and it is uneconomical. Regarding the method of addition, it may be added in advance or may be added during the production,
It may be selected as appropriate in consideration of workability.

As the component (B), one kind or two or more kinds of them are blended in the cosmetic of the present invention.

Oils, waxes, hydrocarbons, fatty acids, which are components used in ordinary cosmetics and quasi drugs, within a range that does not impair the effects of the components (A) and (B).
Alcohols, esters, surfactants, metal soaps, p
Ingredients such as H-adjusting agents, preservatives, fragrances, humectants, powders, ultraviolet absorbers, thickeners, dyes, antioxidants, whitening agents and chelating agents can also be added.

The cosmetic of the present invention can be used in both cosmetics and quasi-drugs.
Examples thereof include lotions, creams, emulsions, gels, aerosols, essences, packs, detergents, bath agents, foundations, dusters, lipsticks and the like.

Experimental Example-1 Effective amount of collagen derived from fish The effective amount of collagen derived from fish against reduction in skin elasticity after ultraviolet irradiation was examined. In the experiment, the back of 6-week-old male mice was irradiated with ultraviolet A waves, and the cream of Comparative Example 1 was applied with or without the hot water extract of Kidachi aloe or with the amount of collagen mixed. Irradiation and application 30
The test was conducted continuously for a day, and the skin elasticity was measured after the test was completed.

The results are shown in Table 1. The control shows the elasticity of mouse skin not irradiated with ultraviolet rays. It was effective by adding hot water extract of Kidachi aloe to the reduction of skin elasticity. The improvement effect of fish-derived collagen depends on its amount,
An excellent effect was shown at 01% or more. However, no enhancement of the effect was observed even if the content was more than 10%.

Experimental Example-2 Hyaluronic Acid Synthesis Promoting Action On cultured skin-derived epidermal keratinocytes (NHEK), Production Example-
1, 100 μg / mL of the hot water extract of Kidachi aloe, the addition of 1,000 μg / mL of the acid-soluble atelocollagen collagen solution of Production Example-4, and the addition of both, and the hot water extract of Kidachi aloe And manufacturing example
The effect of promoting hyalonic acid synthesis in the case of adding both bovine-derived atelocollagen solutions of 6 was examined by the sandwich binding assay method. Hyaluronic acid production ability is 10% of the hyaluronic acid concentration without addition.
The evaluation was made with the ratio (%) set to 0.

As a result, as shown in Table 1, the hyaluronic acid synthesizing ability was 1 in the treatment with the hot water extract of Kidati aloe.
The treatment with the 50% acid-soluble atelocollagen solution increased 130%, and the simultaneous treatment with these increased 200%. However, the effect of the hot water extract of Kidati Aloe was not enhanced by the bovine-derived atelocollagen solution.
