Description

  The present invention relates to a cosmetic material that has an effect of restoring the barrier function of the skin stratum corneum, and further has an antioxidant action and an anti-inflammatory action, maintains or improves the skin in a healthy and fresh state, and is effective in preventing skin aging, and The present invention relates to a cosmetic compounding agent for imparting effects on cosmetics.

The stratum corneum, the outermost skin layer, protects the living body from contact and penetration of foreign matter such as microorganisms and harmful substances, and prevents the evaporation of moisture from the skin surface to keep the skin healthy and fresh. It performs a so-called barrier function.
When this barrier function is reduced due to aging, excessive water work, etc., the water evaporation from the skin surface (Transepidermal Water Loss; TEWL) increases, the water content of the stratum corneum decreases and the dry skin phenomenon occurs. Exhibits rough skin.
In order to prevent this skin barrier function from decreasing and to prevent or improve moisture transpiration from the skin surface, and thus dry skin and rough skin, transepidermal moisture transpiration has been conventionally used using occlusive agents such as petroleum jelly, squalane and ester oil. (TEWL) deterrent method, glycerin, NMF related ingredients (sodium pyrrolidonecarboxylate, sodium lactate, etc.), hydrolyzed collagen, collagen derivatives and other moisturizing ingredients are added to the skin to enhance the water retention capacity of the skin, placenta Methods for promoting keratinization of epidermal cells using cell activation components such as extracts and vitamins have been proposed, but in the case of these conventional methods, the effect is temporary or effective. However, if the amount is increased to obtain a satisfactory effect, it may cause stickiness when applied to the skin, resulting in a decreased feeling of use or safety. There is a drawback such as may occur with in the surface problem.

  In view of the above-mentioned problems in the method and agent for recovering the skin barrier function and maintaining and improving the skin in a healthy, fresh and firm state, both the effectiveness and safety are considered. A new skin barrier function recovery agent with excellent usability and the like, as well as prevention of rough skin, effective improvement of symptoms, high biological safety, good usability, and feeling after use. As a result of earnest research to provide the prepared cosmetics, the extract of the plant belonging to the genus Hydrangea, which is a seed plant belonging to the family Chenopodiaceae, has an excellent skin barrier function recovery action, and the moisture transpiration from the skin It has a remarkable effect on prevention or improvement of skin moisture retention ability, and since it is derived from a natural product, it is highly safe for the living body and has a good feeling of use and meets the above purpose. It led to the issue.

In addition, as a result of further studies by the present inventors, the extract of the plant belonging to the genus Acanthaceae also has an anti-inflammatory action based on an antioxidant action and a cyclooxygenase activity-inhibiting action in addition to an action to restore the skin barrier function. It became clear to have both.
Therefore, according to the cosmetic containing the extract of the plant belonging to the genus Rhizoaceae, the transpiration of moisture from the skin is prevented or the ability to retain the moisture of the skin is improved based on the skin barrier function recovery action of the extract. In addition to preventing rough skin and improving symptoms, it also prevents or improves skin aging by eliminating radicals generated by ultraviolet rays and stress and suppressing inflammation, keeping the skin youthful In addition, the skin aging preventing effect of recovery can be exhibited.

JP 63-192705 A

That is, the present invention first relates to a cosmetic characterized by containing an extract of a plant belonging to the genus Acanthaceae.

  Extraction conditions such as bath ratio, extraction temperature, and extraction time vary depending on the type and pH of the solvent used, or the extraction site and shredding degree of the plant, but for example, in the case of the immersion method using water as the extraction solvent The bath ratio is a weight ratio, and the solvent is in the range of 1 to 50 times, preferably 1 to 20 times the amount of the plant, and the extraction temperature is generally 4 to 100 ° C, preferably 4 to 80 ° C. It is a range. The extraction time is 8 hours to 50 days in the case of cold extraction at 4 ° C., particularly 24 hours to 20 days, 4 hours to 20 days in the case of medium temperature extraction at 40 ° C., particularly 8 hours to 5 days, 80 ° C. In the case of high temperature extraction, the time is preferably 10 minutes to 8 hours, particularly 30 minutes to 3 hours.

The extract solution thus obtained is generally adjusted to a pH of 4 to 8, and may be used as it is as a cosmetic compounding agent, or may be used at an appropriate concentration by vacuum concentration or the like if necessary. . Further, depending on the case, it can be pulverized according to a conventional method such as spray drying or freeze drying.

[Test method]
Ten adult males aged 20 to 50 years were used as subjects, and two test sites were provided on the inner forearm of each subject, and the sites were treated with SDS to artificially cause rough skin.
The control antiseptic water is applied to one of the test sites, and the sample of the present invention is applied to the other side twice a day (morning and evening) for 3 days for 3 days, and the morning after 1 day, 2 days and 3 days after the start of application. Before the sample application, the TEWL of the test site was measured using a barometer (manufactured by Keystone, model SWL2001N). The measurement was repeated three times for each test site, and the average value was taken.
The degree of recovery of the skin barrier function (barrier function recovery rate%) is defined as 100 from the value after 1 day of application when TEWL showed the highest value, and the relative value of TEWL after 2 days and 3 days after application according to the following formula: Asked.
Barrier function recovery rate (%) = TEWL (relative value) after 100-2 days or 3 days

[result]
The results are shown in FIG. In FIG. 1, the barrier function recovery rate (%) is an average value of 10 subjects.
From the result of FIG. 1, it is clear that the extract of the plant of the genus Rhododendron according to the present invention has an excellent barrier function restoring action.

Test Example 3 Anti-inflammatory action based on suppression of cyclooxygenase activity [Sample]
1. 10% aqueous solution of the extract solution of Example 3 (sample of the present invention)
2. Purified water (control)
[Test method]
To 2.52 ml of 20 mM tryptophan / 0.2 MTris-HCl buffer (pH 8.0), 0.03 ml of 40 mM hemoglobin / 0.2 MTris-HCL buffer (pH 8.0) and 0.15 ml of a sample were mixed. After heating to 37 ° C, 0.1 ml of 2 mM arachidonic acid / 0.2 mM Tris-HCL buffer (pH 8.0) and 0.2 ml of 250 unit / ml cyclooxygenase are mixed, and arachidonic acid is used as a substrate for 10 minutes while stirring in a sealed state. A cyclooxygenase enzyme reaction was carried out.
During the course of the reaction, the dissolved oxygen concentration was measured every specified time using a biological oxygen monitor (YSI MODEL 5300), and the oxygen consumption rate over time was calculated with the dissolved oxygen concentration immediately before the reaction as 100%.
When the oxygen consumption rate at each time is χ%, the oxygen consumption amount in 3 ml of the sample solution is obtained by the following equation.
Oxygen consumption in sample solution (μl) = χ / 100 × 5.02 × 3

[result]
The change in oxygen consumption over time is shown in FIG.
As is apparent from the results of FIG. 3, the plant extract of the genus Hydrangea of the present invention has a remarkable cyclooxygenase activity inhibitory effect and is useful as an anti-inflammatory agent.
In addition, the cosmetic of the present invention, which is obtained by blending this genus plant extract, exhibits an excellent effect in preventing skin aging due to the anti-inflammatory action of the extract.
