Description

  The present invention relates to a cosmetic suitable for massage, and more particularly to a cosmetic excellent in use feeling and exfoliation feel.

In addition to the effect of improving the swelling and promoting a feeling of relaxation by promoting blood circulation, the massage has the effect of removing the excess keratin and plaque on the skin and providing a smooth skin feel. In the case of such a massage, in order to improve the slip of fingers and instruments to be massaged and to make the massage easier, usually a massage cosmetic with excellent lubricity is often used. At this time, as cosmetics for scraping off the excess keratin, the skin exfoliating keratin called gonage cosmetics is entangled with spilling scum (Patent Documents 1 to 3), and scrub cosmetics. There is a cleaning cosmetic with a granule composition called (Patent Documents 4 to 6).
Of these, gorge cosmetics do not contain granules, but are blended with clay minerals, resin powders, fibrous powders, etc. with an average particle size of about 40 μm to remove unnecessary keratin, etc. Although it is characterized by an effective feeling due to the residue, the exfoliating effect is weak. On the other hand, the scrub cosmetic is a scrub granule having an average particle size of about 300 μm, which removes unnecessary keratin, and has a feeling of particles and high effectiveness, but there is a feeling of irritation due to the scrub granules, and the granules are gradually washed with water. However, it has the disadvantage that the actual feeling of exfoliating effect does not last.
In recent years, dermabrasion cosmetics have been studied as products that can achieve both a mild feeling of use and a high keratin exfoliation effect as an alternative to the above-mentioned gorgeous cosmetics and scrub cosmetics. This is close to the crystal peeling that has been done in beauty salons in the past, but it is intended to be more gentle to the skin and provide an effective feeling of use. Therefore, there is a need for an optimal powder formulation.

JP 2001-089332 A JP 2000-219618 A JP 2000-169355 A JP 2001-278778 A JP 2000-247860 A JP-A-5-221822

  The present invention has been made in view of such problems of the prior art, and its purpose is to maintain the effective keratin exfoliation effect due to the powder, and to have an appropriate viscosity, spread and slip, and a feeling of use on the skin. An object of the present invention is to provide an optimal cosmetic for a massage that is good and that provides a smooth and transparent skin feel after use.

  As a result of intensive studies to achieve the above-mentioned object, the inventors of the present invention used a specific fibrous powder, a water-resistant powder component that does not disintegrate in a specific water, and a thickener in combination. To obtain a massage cosmetic that maintains the feel of particles obtained, has an appropriate viscosity, has a good spread and a good feeling on the skin, and has an effect of exfoliating exfoliation that was not possible with conventional massage cosmetics The present invention has been completed.

  In the present invention, 0.1 to 20% by mass of silica powder having an average particle size of 75 to 150 μm, 1 to 20% by mass of fibrous powder having an average particle size of 10 to 200 μm, and 0.01% of a thickener. It is cosmetics characterized by mix | blending -2.0 mass%.

  According to the present invention, makeup that is suitable for a massage that feels the exfoliation effect due to the feel of particles obtained from silica powder, has a sustained effect, has an appropriate viscosity, and has good stretchability on the skin. You can get a fee. Moreover, the cosmetics of the present invention have a fresh and good feeling of use without stickiness.

The best mode of the present invention will be described below.
The silica powder having an average particle size of 75 to 150 μm used in the present invention is a water-resistant powder having an exfoliating effect and does not dissolve or swell in cosmetics. The shape of the silica powder is not particularly limited, but is preferably from a spherical shape to a lump shape, and particularly preferably a lump shape. The average particle diameter of 75 to 150 μm is based on the laser diffraction scattering method. When the average particle size is less than 75 μm, the particle feel at the time of application is lacking, and when it exceeds 150 μm, pain is felt during massage.

  As the silica powder used in the present invention, either a commercial product or a synthetic product can be used. Commercially available products include Tokuseal PR (average particle size 100 μm, Tokuyama brand name), Tokuseal UR (average particle size 150 μm, Tokuyama brand name), MS GEL (Dokai Chemicals brand name). Etc. Moreover, what is obtained by neutralization reaction, such as water glass, can be used as a synthetic product.

  Silica powder is blended in the cosmetic material in an amount of 0.1 to 20% by mass, preferably 5 to 15% by mass. If it is less than 0.1% by mass, it is difficult to feel the exfoliation effect because the particle feel of the blended powder cannot be obtained, and the blending significance is lost. Moreover, when it mix | blends exceeding 20 mass%, fluidity | liquidity will be impaired and, in an extreme case, a cream-like property cannot be maintained. There may also be problems with product stability, such as excessive drying of the product.

  As the fibrous powder having an average particle size of 10 to 200 μm used in the present invention, those which swell in the cosmetic and give the cosmetic an appropriate viscosity and good elongation are suitable. The average particle size of 10 to 200 μm is based on the laser diffraction scattering method. Furthermore, the average particle diameter is preferably in the range of 20 to 90 μm. If the average particle size is less than 10 μm, swelling in the cosmetic is weak, that is, good spreading cannot be obtained. On the other hand, if it exceeds 200 μm, the feel of the fibrous powder becomes strong, that is, the feeling on the skin is not good.

  Examples of the fibrous powder include those obtained by processing plant proteins such as crystalline cellulose, powdered cellulose, and grains into fibers. Examples of commercially available fibrous powders having an average particle diameter of 10 to 200 μm used in the present invention include Theolas KG-802 (average particle diameter 50 μm, trade name manufactured by Asahi Kasei Co., Ltd.), Theolas PH-F20JP (average particle diameter 20 μm, Asahi Kasei Co., Ltd. trade name), Theolas PH-30 (average particle size 90 μm, Asahi Kasei trade name).

  The blending amount of the fibrous powder in the cosmetic is 1 to 20% by mass, preferably 2 to 10% by mass. If it is less than 1% by mass, good stretching cannot be obtained. Moreover, when it mix | blends exceeding 20 mass%, fluidity | liquidity will be impaired and, in an extreme case, a cream-like property cannot be maintained. It may also cause problems with product stability such as excessive drying of the product.

  In the present invention, the mass ratio of the silica powder to the fibrous powder is preferably silica powder / fibrous powder = 4/1 to 1/2. By blending the silica powder and the fibrous powder within the above range, the rough particle feeling of the silica powder and the sharp feel of the fibrous powder are moderately mixed to provide a dermabrasion cosmetic. Good particle feeling can be obtained.

The following are mentioned as a thickener used for this invention.
Examples of natural thickeners include, for example, xanthan gum, arabia gum, tragacanth gum, galactan, guar gum, carob gum, caraya gum, carrageenan, pectin, agar, quince seed (malmello), alge colloid (gypsum extract), starch (rice, corn, potato, Wheat), vegetable polymers such as glycyrrhizic acid, and animal polymers such as collagen, casein, albumin and gelatin. Of these, xanthan gum is particularly preferable.

  In addition, the cosmetic of the present invention can obtain a moderate viscosity, good stretch, and slip even without blending an oil, but the slip is further improved by blending a small amount of oil that does not cause stickiness. And a preparation having a better skin feel can be obtained. Also, by blending the oil, compatibility can be enhanced when blending other oil-soluble components. In order to acquire such an effect, it is preferable to mix | blend 1 mass% or more of oil components. In addition, since a sticky feeling will be produced when the amount of oil increases, it is preferable that the amount of oil shall be 10 mass% or less in cosmetics.

Usability when various ingredients are blended into cosmetics [ease of application, spread (goodness of spread), degree of particle feeling at the time of application, richness (when applied on skin and spread with fingers, The cream-like properties are not crushed, that is, the feeling that the cream is uniformly spread). Various ingredients were blended into a typical massage gel formulation, and this was subjected to sensory evaluation of the feel of use by 20 professional panelists. The evaluation is indicated by symbols “」 ”to“ x ”based on the average score obtained according to the following criteria.

4 points: Excellent 3 points: Excellent 2 points: Neither one point: Inferior

(Evaluation criteria)
◎: Average score is 3.5 or more ○: Average score is 3 or more and less than 3.5 △: Average score is 2 or more and less than 3 ×: Average score is less than 2

Example 1 and Comparative Examples 1 to 4
The massage gel formulation shown in Table 1 was prepared, and usability was evaluated for three items of “ease of application”, “navi”, and “degree of particle feel during application”. The results are shown in Table 1 together with the prescription.

According to the results of Table 1, in Example 1 of the cosmetic of the present invention, a thickener for obtaining the viscosity of the product, a fibrous powder for obtaining the spread, and a silica powder for obtaining the particle feel are used. Good results were obtained.
On the other hand, in Comparative Example 1 and Comparative Example 2, since no thickener was blended, an appropriate viscosity was not obtained, and the composition could not be applied on the skin and could not be massaged. Further, in Comparative Example 3, since a thickener was blended, although a certain degree of viscosity was obtained, good “spread” obtained from crystalline cellulose was not obtained, which was incompatible. Moreover, in the comparative example 4, since there was no particle | grain feel of a powder, the effect of exfoliation was not able to be felt. From the above, it was found that a thickener, fibrous powder, and silica powder are essential as components to be blended in the present invention.

Examples 2 to 6, Comparative Examples 5 and 6
The compounding amount of the silica powder of the massage gel cream shown in Table 2 was changed, and sensory evaluation of the feeling of use was performed by 20 professional panels. The evaluation was performed based on the above criteria for three items of “degree of particle feeling at the time of application”, “nob”, and “ease of application”.

(Production method)
In accordance with the manufacturing method shown in Table 1.

From the results of Table 2, it was found that a particle feel can be obtained during coating at a silica powder content of 0.1 to 20.0 mass%. Particularly preferred was a good particle feel when the blending amount of silica powder was 5.0 to 15% by mass.
On the other hand, as in Comparative Example 5, when the blending amount of the silica powder is 0.05% by mass, a sufficient particle feel cannot be obtained, that is, the effect of exfoliation of the keratin is obtained to obtain a particle feel during coating. The amount of silica powder is insufficient. Further, as in Comparative Example 6, when the blending amount of the silica powder was 45% by mass, the fluidity of the product was impaired, and the feel of the particles was excessive, and good evaluation was not obtained.

  In view of the above, the silica powder should be blended in an amount of not less than 0.1% by mass, preferably not less than 2.0% by mass in order to obtain a particle feel of the powder. It was found that the upper limit amount is 20.0% by mass or less, preferably 15.0% by mass or less.

Examples 7 to 11 and Comparative Examples 7 and 8
The blending amount of the fibrous powder of the massage gel cream shown in Table 3 was changed, and the sensory evaluation of the feeling of use was performed by 20 professional panels. The evaluation was performed based on the above criteria for three items of “degree of particle feeling at the time of application”, “nob”, and “ease of application”.

(Production method)
In accordance with the manufacturing method shown in Table 1.

From the results of Table 3, as shown in Examples 7 to 11 of the cosmetics of the present invention, it is good as a massage cosmetic by blending in the range of 1.0 to 20.0% by mass as the blending amount of the fibrous powder. Became a prescription. More preferably, as shown in Examples 8 to 10, by adding 2.0 to 10.0% by mass of the fibrous powder, an appropriate “particle feel”, “navi”, “ease of application” ”Became a good prescription as a massage cosmetic that is compatible.
On the other hand, when the fibrous powder is 0.1% by mass as shown in Comparative Example 7, not only “swelling” on the skin is deteriorated but also “particle feel” of the silica powder becomes stronger than necessary, and the massage cosmetic. As unsuitable. Further, as shown in Comparative Example 8, when the fibrous powder is 30.0% by mass, not only the fluidity is impaired, but also the “particle feel” obtained with the blended silica powder is impaired. The feeling was not obtained and it was unsuitable.

  In view of the above, in order to obtain an appropriate “navi”, “ease of application”, and an appropriate “particle feel” as the massage material of the present invention, the blending amount of the fibrous powder is 1.0% by mass or more. It was found that 2.0% by mass or more is preferably blended, and the upper limit is 20.0% by mass or less, preferably 10.0% by mass or less.

Examples 12-16
The blending ratio of the silica powder and the fibrous powder of the massage gel cream shown in Table 4 was changed, and the sensory evaluation of the feeling of use was performed by 20 professional panels. The evaluation was performed based on the above-mentioned criteria for two items of “degree of particle feeling at the time of application” and “navi”.

(Production method)
In accordance with the manufacturing method shown in Table 1.

From the results of Table 4, as shown in Examples 12 to 14, silica powder and fibrous powder for obtaining a good “particle feel at the time of application” and a good “navi” for the cosmetics of the present invention. The mixing ratio of 4: 1 to 1: 2 is suitable.
As in Example 15, when the ratio of silica powder to fibrous powder is 6/1, since there is little fibrous powder, good “spread” is impaired, particle feeling becomes stronger, and the skin burden becomes stronger. Tend. Further, when the ratio of the silica powder to the fibrous powder is 1/3 as in Example 16, it is difficult to obtain a sufficient “particle feel”, and it is difficult to obtain an actual feeling of exfoliation effect. From the above, the silica powder / fibrous powder = 4: 1 to 1: 2 is preferable as the blending mass ratio of the silica powder and the fibrous powder.

Examples 17 and 18, Comparative Examples 9 and 10
The particle size of the silica powder of the massage gel cream shown in Table 5 was changed, and the sensory evaluation of the feeling of use was performed by 20 professional panels. The evaluation was performed based on the above criteria for two items of “degree of particle feeling at the time of application” and “ease of application”.

  According to the results of Table 5, as shown in Examples 17 and 18, by selecting an average particle diameter of the bulk silica to be blended having an average particle diameter of 75 μm to 150 μm, a favorable “particle feel” and suitable It was possible to make the massage cosmetics compatible with “easy to apply”. As shown in Comparative Example 9, when a particle having an average particle diameter of 14 μm was selected, the degree of particle feeling was too weak, meaning that the blending significance was lost, which was inappropriate. On the other hand, as shown in Comparative Example 10, when a particle having an average particle size of 230 μm was selected, the particle feel was too strong, and the skin was excessively stimulated. From the above, it was found that 75 μm to 150 μm is suitable as the average particle size of the massive silica to be blended.

Examples 19-21, Comparative Example 11
The particle diameter of the fibrous powder of the massage gel cream shown in Table 6 was changed, and this was subjected to sensory evaluation of the feeling of use with 20 professional panels. The evaluation was performed based on the above-mentioned criteria for two items of “degree of particle feeling” and “nobori”.

(Production method)
In accordance with the manufacturing method shown in Table 1.

  According to the result of Table 6, as shown in Example 19, as the average particle diameter of the fibrous powder to be blended, an average particle diameter of 20 μm or more gives a good particle feel and good spread. As shown in Example 21, it became more suitable by selecting a particle having an average particle diameter of 50 μm or 90 μm. On the other hand, as shown in Comparative Example 11, when the average particle size greatly exceeds 200 μm as the particle size range is 300 μm, it is not suitable because the particle feel is too strong and an excessive load is applied to the skin. From the above, it was found that the average particle diameter of the fibrous powder blended in the present invention is 10 to 200 μm, preferably 20 to 90 μm.

Examples 22 to 27, Comparative Example 12
The thickener of the massage gel cream shown in Table 7 was changed, and the sensory evaluation of the feeling of use was performed by 20 professional panels. The evaluation was performed based on the above criteria for three items of “ease of application”, “nob”, and “feel”. Examples 22 to 25 are reference examples not included in the present invention.

  According to the results in Table 7, as shown in Examples 22 to 27, the viscosity and the spread are good for massage use by blending the thickener to 0.01% by mass or more, preferably 0.05% by mass or more. Goodness is obtained. By selecting a cross-linked N, N-dimethylacrylamide-2-acrylamido-2-methylpropanesulfonic acid sodium copolymer, which is a water-swellable microgel thickener, it is especially good for massage use. "Is obtained. On the other hand, if the blending amount of the thickener is less than 0.01% by mass, a sufficient viscosity cannot be obtained, which is unsuitable for practical use. From the above, it can be said that a water-swellable microgel thickener is suitable as a thickener to be blended.
