Description

  The present invention relates to a cosmetic characterized by containing an extract obtained from Elaeagnus glabra Thunb.

  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 a conventional plant-derived extract.

  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 tsurugumi extract have a particularly high skin beautifying effect and complete the present invention. It came.

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

As an effect of the present invention, the Tsurugumi extract effectively eliminates pigmentation, rough skin, and the like.

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

  The blended amount of the extract of tsurugumi 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]
After immersing 0.4 kg of Tsurugumi (dry product) in 1.0 kg of 30% 1,3-butylene glycol aqueous solution and extracting it at 55 ° C. overnight, it is 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 Tsurumi extract (evaporation residue; 0.5 w / w%).

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

Radical tolerance enhancement action Rabbit cornea-derived cells were used as radical tolerance evaluation cells, seeded at 20,000 cells / well in a 96-well microplate, pre-cultured for 24 hours, and then added with tsurugumi extract of the present invention. The medium was replaced with a fetal calf serum-containing Eagle MEM medium and cultured for 24 hours. Measurement of changes in the amount of red dye neutral red taken up into cells and changes in cell activity by the MTT reduction method by contacting 200 mM t-butyl peroxide as a radical at 37 ° C. for 1 hour. The evaluation was determined.

  As a result, it was found that Tsurugumi extract enhances radical tolerance of rabbit cornea-derived cells. (Tables 1. and 2.)

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

As a result, a clear tendency to pigmentation was observed in cosmetics containing tsurugumi extract as compared with cosmetics conventionally used. (Table 4.)

(3) Skin quality improving action 10 subjects complaining of dry skin are grouped, 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 5 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.

Results of skin quality improvement effect determination As a result, the cosmetics containing tsurugumi extract showed a clear tendency to improve skin quality as compared with the cosmetics of Comparative Examples. (Table 6.)
