Abstract

PURPOSE:To provide a novel cosmetic containing the water-soluble extract of coconut fruits as an active ingredient, simultaneously having a beautifully whitening action, an antiinflammatory action and a water retention which are highly stable, and preferable also on safety. CONSTITUTION:Coconut fruits are ground and then extracted with water or with the water and a water-soluble solvent under heating, and the extract is concentrated. The cosmetic simultaneously having a beautifully whitening action, an inflammatory action and a water-retaining force contains the concentrated extract as a raw material. The base material is used as a raw material to provide the cosmetic such as a beauty water, a cream, an emulsion, a shampoo. a foundation, a lip cream, a lip stick. etc. The water-soluble extract of the coconut fruits is preferably used in an amount of 0.1-5.0wt.% based on the total amount of the cosmetic.

BACKGROUND OF THE INVENTION Although there are some unclear points regarding the mechanism of skin spots, freckles, etc., melanin pigments are generally formed due to hormonal abnormalities and ultraviolet rays from the sun, and this is due to the fact that the It is thought that it will be abnormally deposited. For the treatment of such stains and freckles, a substance that inhibits the thyrodinase activity present in the skin and suppresses melanin production, for example, a method in which a large amount of vitamin C is administered, glutathione is an ointment, and cream is used. , A lotion or the like and locally applying it.
In Europe and America, hydroquinone preparations are used as medicines.

[Problems to be Solved by the Invention] Vitamin C contains heat,
It has poor stability over time with respect to light, and causes discoloration and odor particularly in systems containing water. On the other hand, the use of hydroquinone type is limited because of its safety problems such as skin irritation and allergenicity. Further, there is a problem in terms of stability because it is easily oxidized by air. Thiol-based compounds such as glutathione and cysteine have a strong offensive odor and are easily oxidized and their effects are slow. In addition, 2-mercaptoethylamine salt, N- (2-mercaptoethyl) dimethylamine salt and the like are known to decolorize the skin of black guinea pigs, but since white spots easily occur after decolorization, they are generally used.

The tyrosinase activity inhibitory ability of the 5% aqueous solution was measured before and after the incubation at 37 ° C. for 2 weeks. As a comparative example, ascorbic acid, loofah water, and hot water extract of loofah fruits, which have been conventionally used as cosmetics, were similarly tested. The sample used was the extract obtained in Example 1. The hot water extract of loofah (comparative example) was prepared by extracting 10 g of the dried product with hot water (95 ° C, 3 hours, 30 hours).

The results of these tests are shown in Table 1. As is clear from Table 1, the water-soluble extract of coconut palm fruit obtained in Example-1 has a more remarkable thyrodinase activity inhibitory activity than loofah water and hot water extract of loofah. It is recognized that the product has a good thermostability and has a stronger tyrosinase activity inhibitory effect than that of vitamin C after standing for 2 weeks at 37 ° C. In addition, in these stability tests, no odor or discoloration was observed in the water-soluble extract of coconut palm fruit.

% And 1.0% of each aqueous solution, a histamine release inhibition test was carried out. As a comparative example, hot water extracts of loofah water and Kitia aloe, which have been conventionally used in cosmetics, were similarly tested. The water-soluble extract of coconut palm, loofah water and hot water extract of loofah are the same as those used in Experimental Example 1.

Method for measuring water vapor evaporation inhibition rate: 2 ml of each sample solution is placed in a standard bottle and allowed to stand at a temperature of 25 ° C. and a relative humidity of 50%. After standing for 4 days, the water evaporation amount of each sample solution was measured, and the water evaporation rate was calculated from the following equation. In the formula, A means the water evaporation amount of each sample, and B means the water evaporation amount of the blank (distilled water). Rejection rate (%) = (1-A / B) × 100

Efficacy Test Example 4 Usage Test A usage test was carried out using 30 healthy subjects. As the samples, the cosmetics of Examples 5 and 6 were used, and the weight% of the water-soluble extract of coconut palm fruit was changed. A UV-B lamp (TOSHIBA FL-20SE) was used to irradiate the site of 2 cm square on the inner side of the forearm of the subject with ultraviolet rays having an intensity of 3 mw / cm 2 for 1 minute. Each sample was applied to each site twice daily in the morning and evening for 3 days, and then the effect of suppressing inflammation was surveyed and evaluated. The effect of suppressing pigmentation after one month of use and the moist feeling of the skin are also questioned.
An evaluation was performed by conducting a survey. Incidentally, one of the sites irradiated with ultraviolet rays was a control in which nothing was applied. The evaluation criteria of the questionnaire were based on the following, and evaluated in comparison with the control.

Efficacy Test Example 5 Safety Test In order to clarify the safety of the water-soluble extract of coconut palm fruit of the present invention, a primary irritation test for humans was conducted by an occlusive patch test. That is, the fin chamber
Using EPITEST, 30 healthy people were occluded on the flexed side of the forearm for 48 hours, and after removal of the patch test plaster, the average value of the judgments made 1 hour, 24 hours, and 48 hours later. It was judged using. As the sample, the water extract obtained in Example 1 was used, and the coating concentration was 10% (W / W) aqueous solution.
Distilled water was used as a control. As a result of the determination, no erythema was observed in the water extract of coconut palm fruit, while a slight erythema was observed in 5 of the distilled water as a control. From these results, it was confirmed that the water-soluble extract of coconut palm has extremely low primary irritation and is highly safe to the skin. Also,
The water-soluble extracts of coconut palm fruits obtained in Examples 2 to 4 were also tested in the same manner, and were found to be similarly highly safe to the skin.
