Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a hypoallergenic cosmetic composition comprising a plant extract having a blood circulation promoting effect and a water-soluble film-forming polymer.

[0002]

2. Description of the Related Art Conventionally, cosmetics containing a plant extract having a blood circulation promoting effect for the purpose of improving skin condition and preventing skin aging have been developed. However, a plant extract having a blood circulation promoting effect may give a stimulating feeling to sensitive skin, and cannot be incorporated in cosmetics for such skin, or can be incorporated only at a low concentration.

[0003]

That is, an object of the present invention is to provide a hypoallergenic cosmetic composition containing a plant extract having a blood circulation promoting effect.

[0004]

Means for Solving the Problems In view of the above circumstances, the present inventors have conducted intensive studies and as a result, have found that a cosmetic composition comprising a plant extract having a blood circulation promoting effect and a water-soluble film-forming polymer has been described. The inventors have found that the object can be solved, and have completed the present invention. That is, the present invention is characterized by containing (A) a plant extract having a blood circulation promoting effect and (B) a water-soluble film-forming polymer (excluding a carboxyvinyl polymer and an alkyl-modified carboxyvinyl polymer). And a cosmetic composition.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION The plant extract having a blood circulation promoting effect of the component (A) used in the present invention includes, for example, Ashitaba, Arnica, Ginkgo, Emmeso, Dutch mustard, chamomile, Clara, Gentian, burdock, rice,
Hawthorn, Atlantic hawthorn, Atlantic shrew, Sansha, Shiitake, Shobu, Senkyu, Assemble, Thyme, Chimpanzee, Touki, Tonin, Spruce, Carrot, Butcher Bloom, Fudo leaf, Button, Malonier, Melissa, Yuzu, Yokuinin, Rosehip, Rose Marie and the like.

[0006] The method for preparing the plant extract is not particularly limited, but is usually any part of the plant, for example, whole plant, root,
Stems, flowers, fruits are dried, cut, etc., and then water, methanol, ethanol, flopanol, propylene glycol, 1,3-butylene glycol, tityl acetate, ether, liquid paraffin, soybean oil, lower fatty acid glyceride, or a mixture thereof It is obtained by extraction with a mixed solvent. The obtained extract may be provided in any form of a liquid or a dry extract.

[0007] The above-mentioned plant extracts are used alone or in combination. The amount of the plant extract is preferably 0.0001 to 5% by mass in terms of dry residue based on the total amount of the cosmetic composition.

The water-soluble film-forming polymer of the component (B) used in the present invention is a water-soluble film-forming polymer other than the carboxyvinyl polymer and the alkyl-modified carboxyvinyl polymer. Gum arabic, alginic acid or salt thereof, carrageenan, agar, guar gum, quinceed, tamarind gum, dextrin, dextran, starch, locust bean gum, karaya gum, tragacanth gum, pectin, quince, chitosan, xanthan gum, gellan gum, hyaluronic acid or salt thereof , Pullulan, methylcellulose, ethylcellulose, hydroxyethylcellulose, hydroxypropylcellulose, hydroxypropylmethylcellulose, carboxymethylcellulose, cationized cellulose, polyacrylamide, Polyvinyl alcohol, polyvinyl pyrrolidone, and the like. Here, the carboxyvinyl polymer is a water-soluble polymer having a main chain of acrylic acid and a carboxyl group containing allyl sucrose or pentaerythritol as a cross-linking agent. For example, commercially available products such as Carbopol 940, 941, 980, 981 (B
F Goodrichi). Also,
An alkyl-modified carboxyvinyl polymer is a compound having 1 carbon atom.
A copolymer of a long-chain alkyl acrylate monomer and an olefinically unsaturated carboxylic acid monomer in the range of 0 to 30;
And a water-soluble polymer obtained by copolymerizing 50 to 99% by mass of an olefinically unsaturated carboxylic acid monomer. In some cases, in order to adjust the properties of the copolymer, an olefinic polyfunctional monomer was blended and polymerized. It is a copolymer having a crosslinked structure. Specific examples of the copolymer include those commercially available under the trade names of PEMULEN and Carbopol 1342 (both manufactured by BF Goodrich Chemical Co., Ltd.).

The water-soluble film-forming polymer of the component (B) is used alone or in combination with the cosmetic composition. The compounding amount is preferably 0.01 to 5.0% by mass based on the total amount of the cosmetic composition.

In the cosmetic composition of the present invention, in addition to the above-mentioned components, various components such as an oil agent, a surfactant, a humectant, a preservative, a fragrance, a coloring agent, a solvent and the like which are usually used in cosmetics are used. It can be appropriately blended within the range for achieving the object.

Specific uses of the cosmetic of the present invention include:
Skin care products, hair products, makeup products, UV protection products, fragrance products, cleaning products and the like. In particular, from the viewpoint of low irritation, which is the effect of the present invention, cosmetics for improving rough skin for sensitive skin or for preventing aging for sensitive skin are preferred. In addition, the form of the product, transparent liquid, emulsion,
It can be applied to cream, gel, multi-layer liquid, foam, spray, etc.

[0012]

The present invention will be described below in more detail with reference to examples, but the present invention is not limited to these examples. The unit of the following compounding amount is% by mass. The plant extract used was an extract extracted with a hydrophilic solvent. In addition, the evaluation of the stimulus sensitivity in the examples was performed by using a sample using 20 sensitive skin panelists, and was evaluated based on a questionnaire response. The evaluation criteria are as follows. The evaluation was made based on the total score of the scores of the 20 participants.

[Stimulus] +++: A considerable sense of irritation (score 3) ++: A sense of irritation (Score 2) +: A slight irritation (Score 1) −: No irritation (Score) 0)

Example 1 Each plant extract (commercially available extract extracted with a hydrophilic solvent)
The stimulus sensitivity test was performed on the 10% by mass aqueous solution of the above and the liquid of Table 1 in which the film-forming polymer (0.2% by mass) was combined with the 10% by mass aqueous solution, and the results of Table 1 were obtained.

[Table 1]

Example 2 (Lotion) A lotion was prepared according to the formulation shown in Table 2 below, and the obtained product was tested for the above-mentioned irritation sensitivity. Table 4 shows the results.

[Table 2]

Example 2 (Cream) A cream was prepared according to the formulation shown in Table 3 below, and the obtained product was tested for the above-mentioned irritation sensitivity. Table 4 shows the results.
Shown in

[Table 3]

[Table 4]

From the above results, it was found that a cosmetic composition comprising a plant extract having a blood circulation promoting effect and a water-soluble film-forming polymer did not give a stimulating feeling to sensitive skin. The reason for this effect is considered to be that, by incorporating the film-forming polymer, the plant extract is gradually released from the polymer film when applied to the skin, and the irritating feeling is reduced. In addition, the cosmetic composition of the present invention was evaluated as having improved skin condition after use.

[0022]

EFFECT OF THE INVENTION It is clear that the cosmetic composition of the present invention comprising a plant extract having a blood circulation promoting effect and a water-soluble film-forming polymer is hypoallergenic.
