Description

  [Technical Field] The present invention relates to a cosmetic comprising an extract obtained from polygonatum odoratum var.

  There have been many cosmetics formulated with plant extracts so far, but the actual effect has not yet been satisfactory.

The present invention provides a cosmetic having a high skin beautifying effect that could not be satisfied by a cosmetic containing other conventional plant-derived extracts.

  As a result of intensive studies on the skin beautifying effect of cosmetics formulated with plant extracts, the present inventors have found that cosmetics formulated with an extract of Amadokoroh have a particularly high skin beautifying effect and complete the present invention. It came.

  The present invention relates to a cosmetic characterized in that a high skin-beautifying effect is imparted by blending an extract of Amadocoro.

  As an effect of the present invention, pigmentation, roughness, rough skin and the like are effectively eliminated by blending an amadokoroko extract into cosmetics.

  The cosmetic of the present invention is characterized by blending an extract of Amadocoro.

  The blending amount of the Amadocoro extract in the cosmetic of the present invention is 0.0001 to 10.0% by weight, more preferably 0.001 to 1.0% by weight in terms of dry matter. If the blending amount is less than 0.0001% by weight, the effect of the present invention is poor, and if it is 10.0% by weight or more, an effect commensurate with the blending amount cannot be expected.

  As the cosmetics of the present invention, skin cleansing cosmetics such as facial cleansers, lotions, cosmetic liquids, emulsions, creams, gels, packs, haptics, makeup cosmetics such as foundation creams and foundations are used as they are, or aerosol type Various dosage forms such as cosmetics used in the pump type, extrusion type, or similar mechanism, and bath agents can be provided.

  The cosmetics of the present invention include water, alcohol, surfactants (cations, anions, nonions, amphoteric surfactants, etc.), humectants (glycerin, 1,3-butylene glycol, propylene glycol, amino acids, urea, pyrrolidonecarboxylic acid). Acid salts, nucleic acids, monosaccharides, oligosaccharides and their derivatives), thickeners (polysaccharides, polyacrylates, carboxyvinyl polymers, polyvinylpyrrolidone, polyvinyl alcohol, chitin, chitosan, alginic acid, carrageenan, xanthan gum) , Methylcellulose, etc. and their derivatives), fats and oils (waxes, petrolatum, hydrocarbons, triglycerides, ester oils, etc. and their derivatives), preservatives (oxybenzoic acid derivatives, dehydroacetate, phenoxyethanol, etc., and their derivatives, etc. ),Fungicide( Ou, triclocarbanilide, salicylic acid, hinokitiol, etc. and their derivatives), UV absorbers (paraaminobenzoic acid, methoxycinnamic acid, etc. and their derivatives), anti-inflammatory agents (allantoin, glycyrrhizic acid, etc. and their derivatives) Others), whitening agents (arbutin, ellagic acid, glutathione, kojic acid, cysteine, pantethein-S-sulfonic acid, hydroquinone, resorcin etc. and their derivatives), antioxidants (tocopherol, BHA, BHT etc. and their derivatives) Etc.), chelating agents (edetic acid, hydroxyethanediphosphonic acid, etc. and derivatives thereof), plant extracts (aloe, ugon, duck, seaweed, chamomile, licorice, kikuwa, touki, buttons, maronier, rosemary, eucalyptus, etc. and These components refined products or fermented products), animal extracts (milk, various peptides, placenta, royal jelly, etc. and these contained component purified products or fermented products), pH adjusters (inorganic acids, inorganic acid salts, organic Acids, organic acid salts, etc. and derivatives thereof), vitamins (vitamin A, vitamin B, vitamin D, etc. and derivatives thereof) within the range of achieving the object of the present invention, 0.001 to 99 .9% by weight can be blended. In addition, the component which comprises the cosmetics of this invention is not restricted above-mentioned at all, If it is a component which can be used for cosmetics, it can select arbitrarily.

  In the case of a haptic agent, in addition to the above components, a base (kaolin, bentonite, etc.) and a gelling agent (polyacrylate, polyvinyl alcohol, etc.) within the range of achieving the object of the present invention are 0.001 to 99.9. It can mix | blend in the range of weight%.

In the bath preparation, sulfate, bicarbonate, borate, pigment, moisturizer is appropriately blended in the range of 0.001 to 99.9% by weight within the range of achieving the object of the present invention, powder type, It can be prepared as a liquid type.

  EXAMPLES Hereinafter, although an Example demonstrates the structure of this invention in detail, this invention is not limited by this. Prior to examples, production examples and test methods performed in each example will be described.

[Production Example 1]
Amadokoro (dried product) 0.4 kg is immersed in 1.0 kg of 30% 1,3-butylene glycol aqueous solution, extracted at 55 ° C. overnight, and then allowed to cool at room temperature. Next, after filtering with No. 1 filter paper, the filtrate was allowed to stand in a refrigerator (4 ° C.) for 1 day. This solution was filtered again to obtain 0.9 kg of Amadocoro extract (evaporation residue; 0.5 w / w%).

[Production Example 2]
Amadokoro (dried product) (0.4 kg) was immersed in 1 liter of ethanol, extracted at room temperature for 1 week, filtered through No. 1 filter paper, and the filtrate was allowed to stand in a refrigerator (4 ° C.) for 1 day. This liquid was filtered again to obtain 0.9 kg of Amadocoro extract (evaporation residue; 0.3 w / w%).

Cell activation effect Human skin-derived fibroblasts were used as cells for cell activity evaluation, seeded in a 96-well microplate at 30,000 cells / well, pre-cultured for 24 hours, and then the amadocoro extract of the present invention was added. The eagle MEM medium containing 10% fetal calf serum was replaced and cultured for 48 hours. The cell activity was measured by the MTT reduction method and evaluated as cell activity.

As a result, Amadochoro extract promoted the activity of human skin-derived fibroblasts depending on the concentration of addition. (Table 1.)

(2) Pigmentation lightening evaluation test For Example 1 and Comparative Example 1, 20 healthy volunteers with pigmentation were recruited for each volunteer, and commercially available whitening cosmetics (contained with stabilized vitamin C derivatives) used in the past. The pigmentation lightness after 4 weeks from the start of use was evaluated on the basis of the criteria shown in Table 2. The results are shown in Table 3. There were no complaints of skin abnormalities throughout the study period.

Table 2 Judgment criteria for lightness A Very remarkably light B Remarkably light C Slightly light D No change E Exacerbation

As a result, it was found that the cosmetics containing amadocoro extract showed a clear tendency to pigmentation compared with the cosmetics conventionally used. (Table 3.)

(3) Skin quality improving action 10 subjects who complained of dry skin are treated as a group, and the cosmetics of Examples 1 to 3 and Comparative Examples 1 to 3 are applied to the entire face twice a day in the morning and evening. The cosmetics of Examples 4 to 6 and Comparative Examples 4 to 6 were applied to the entire face once every morning. For the baths of Example 7 and Comparative Example 7, the bath was 50 grams against 200 liters of hot water. Table 4 is used to bathe once a day. Based on these criteria, the skin quality improving effect was evaluated. The determination was made 4 weeks after the start of use of the cosmetic and bath preparation. No one complained of skin abnormalities throughout the study period.

Table 4. Criteria for evaluating skin quality improvement A A feeling of rustling is extremely light. B A feeling of rustling is remarkably light. C A feeling of rustling is slightly light. D No change is observed.

Results of skin quality improvement effect determination As a result, the amadocoro extract-containing cosmetics showed a clear tendency to improve the skin quality as compared with the comparative example cosmetics. (Table 5.)
