Description

The present invention relates to a solid powder cosmetic, and more particularly to a solid powder cosmetic having excellent impact resistance, a moist feeling, a make-up, and a light spread.

Solid powder cosmetics typified by eye color and powder foundation are cosmetics containing powder as the main component and appropriately mixed with pigments and oils, and are widely used by consumers because they are easy to use and have excellent portability. It is supported. However, since the solid powder cosmetic contains powder as the main component, the light spread and spread on the skin at the time of application may be impaired. Therefore, a spherical powder may be contained in order to obtain a light spread and spread, but if the spherical powder is contained, the bonding force between the powders tends to be weakened, and the cosmetic is damaged by an external impact such as dropping. There was a case. Furthermore, since the main component is powder, we have not been able to obtain satisfactory cosmetics and moisturizing feeling.

In order to solve the above problems, various studies have been conducted. For example, as a technique for improving impact resistance while containing spherical powder, a technique for using a combination of plate-shaped powder and magnesium carbonate, and powder containing spherical powder as a main component and solid oil has been proposed. (Patent Document 1). Further, as a technique for improving the moist feeling while containing spherical powder, a technique for using tris (ethoxyethoxyethyl) phosphate in combination with a silicone elastomer spherical powder has been proposed (Patent Document 2).

Japanese Unexamined Patent Publication No. 2012-02982 Japanese Patent No. 5349867

However, although the impact resistance is improved by the technique using a combination of plate-shaped powder and magnesium carbonate, and spherical powder and solid oil (Patent Document 1), when magnesium carbonate is contained, a feeling of stain on the skin is felt. I was not satisfied with the light spread. On the other hand, in the technique (Patent Document 2) that uses a combination of Tris (ethoxyethoxyethyl) phosphate, which has improved light spread and moist feeling, and silicone elastomer spherical powder, Tris (ethoxyethoxyethyl) phosphate, which is a water-soluble moisturizer, is used. It was used, and it was easy to remove from sweat, etc., and I could not obtain a satisfactory one with regard to makeup retention.

Therefore, there has been a demand for a solid powder cosmetic having excellent impact resistance, a moist feeling, a make-up, and a light spread.

In such a situation, the present inventor has been enthusiastically studying whether it is possible to develop a solid powder cosmetic that combines spherical powder and other materials to improve impact resistance, moist feeling, and make-up lasting in addition to light spreading and spreading. rice field. As a result, we focused on polyurethane having an isocyanate group that has excellent affinity with the skin, and when a specific polyurethane gel composition and spherical powder were combined, surprisingly, in addition to a light improvement in spreading and spreading resistance, We have found that the impact resistance and cosmetic durability are significantly improved, and have completed the present invention.

Hereinafter, the present invention will be described in detail. In addition, in this specification, "-" shall mean the range including the numerical values before and after it. In the present specification, the percentage is expressed by mass unless otherwise specified.

The component (A) polyurethane gel composition used in the present invention is a polyurethane gel composition containing the component (A-1) polyurethane and the component (A-2) oil. The polyurethane gel composition can be obtained by producing the polyurethane gel composition by using the raw material of the polyurethane component (A-1) in the presence of the oil component (A-2).

Here, the component (A-1) polyurethane is represented by HO-R ³ -OH (in the formula, R ³ represents a linear or branched C2-C6 alkylene group which may have an ether bond). It is a polyurethane that uses glycol.
Further, the polyurethane component (A-1) preferably contains at least the following polyurethane (i) or (ii).
More preferably, the component (A-1) polyurethane has (i) a hydrogenated polybutadiene having an isocyanate group at the terminal and (b) HO-R ³ -OH (in the formula, R ³ has an ether bond. It may be a polyurethane obtained by reaction with a glycol represented by a linear or branched C2-C6 alkylene group), or (ii) (c) with a hydrogenated polybutadiene having a hydroxyl group at the terminal. d) Reaction of the diisocyanate compound with (b) a glycol represented by HO-R ³ -OH (where R ³ in the formula represents a linear or branched C2-C6 alkylene group which may have an ether bond).

The novel polyurethane gel composition used in the present invention has been found as a result of intensive research and development on gel materials by the inventors in order to obtain a cosmetic film of an oil-soluble gel having high gloss, elasticity and restoring force. It is a gel composition that has been put out.

The inventors have been conducting research using silicone rubber, polysaccharides, and water-based polyurethane as restorative materials. However, these materials had advantages as well as drawbacks to be solved. Specifically, silicone rubber has the disadvantage of lacking luster and lacking restoring force; polysaccharides have the disadvantage of having weak restoring and restoring force; water-based polyurethane has a limited color gamut because it is water-based, and has sufficient luster. It had the serious drawback of not being;
However, as a result of diligent studies, the inventors have found that in the presence of an oil agent, HO-R ³ -OH (in the formula, R ³ may have an ether bond is a linear or branched C2-C6 alkylene). Polyurethane synthesis was carried out using glycol represented by (representing a group), and a novel gel material was obtained by chance. The novel gel material had a special function of high gloss, elasticity, and restoring force, as shown in Examples described later. This was an unpredictable effect for the inventors.
It is known that polyurethane is obtained by reacting diisocyanate with a polyol. However, there is no example of using polyurethane as an oil-soluble gelling agent, and the polyurethane gel composition of the present invention was found by a new idea of producing in the presence of an oil agent.

The concept of the polyurethane gel composition used in the present invention is still under intense study, but at the present time, the inventors think as follows.

The inventors believe that it has a hydrophilic group-associative thickening mechanism. (2) The polyurethane imparts flexibility and oil solubility because the hydrophobic portion in the molecule is a low crystalline hydrocarbon; the polar groups of the hydrophilic portion in the molecule interact with each other. The inventors think that it imparts gelling power and restoring power. (3) The inventors think that a three-dimensional structure is formed into a transparent gel by finely taking a three-dimensional structure by a hydrophilic group-associating thickening mechanism.

[Evaluation of gel]
From the polyurethane gels obtained by the above-mentioned production method, the polyurethane gel composition of Production Example 2 was evaluated with respect to the gel load value for various oils commonly used in cosmetics and the transparency of the gel (Test Example 1). ~ 6). The results are shown in Table 1. In addition, various evaluation methods are as follows. The gel load value of the component (A) polyurethane gel composition of Production Examples 1 to 5 was 2.5 to 7.5 N, and the weight average molecular weight was 10,000 to 100,000.

[Measurement of load value and evaluation of gel strength]
The polyurethane gel composition of Production Example 2 and various oils shown in Table 1 were heated and dissolved at 85 ° C. and cooled to 30 ° C. to prepare an elastic gel (Test Examples 1 to 6). The load value of the gel was measured using a load measuring machine (manufactured by FUDOH) under the conditions of a 2 cmφ spherical adapter, 2 cm / min, and a 10 mm needle. The gel strength was evaluated by this. As a result of Test Examples 1 to 4, it was confirmed that the load value tends to be higher as the oil agent has a smaller number of hydroxyl groups in the molecule. It is considered that this is because the hydroxyl group in the oil agent affects the hydrophilic group portion in the hydrophilic group-associating thickening mechanism of the polyurethane gel, resulting in a decrease in thickening.

[Measurement and evaluation of transparency]
For the transparency of various gels (Test Examples 1 to 6) shown in Table 1, the transmittance at 700 nm was measured using a transmittance measuring machine (manufactured by Shimadzu Corporation). As a result, in all the gels of Test Examples 1 to 6, 90% or more showed good transparency (⊚).

[Measurement and evaluation of self-restoring force]
The self-restoring force was evaluated using the polyurethane gel composition of Production Example 2 and the dextrin fatty acid ester gel of Production Comparative Example 2. Each measurement sample is elastic by diluting it with cetyl 2-ethylhexanoate so that the pure content becomes 10.5%, heating it at 85 ° C, pouring it into a jar, and cooling it to 30 ° C. A gel was prepared. From the time when a load of 5 g was applied to the prepared sample using a texture analyzer (manufactured by Ei Seiki Co., Ltd.) with a 2 cmφ spherical adapter, 7 times at a speed of 1 mm / min and under the condition of inserting a 5 mm needle. By repeating the same operation, it was confirmed that the gel structure was not destroyed by the load and that it had a restoring force. A schematic diagram of the measurement is shown in FIG.
As a result, in the dextrin fatty acid ester gel of Production Comparative Example 2, the gel structure was destroyed by repeated loading and the same curve was not obtained, whereas in the polyurethane gel composition of Production Example 2, the gel was formed by repeated loading. By following the same curve without collapsing, it was found that the gel has high resilience. Further, since the value of the load value itself was also higher than that of the dextrin fatty acid ester gel of Production Comparative Example 2, it was found that the elasticity was excellent.

From the above studies, it was found that the component (A) polyurethane gel composition used in the present invention is a highly novel gel having excellent transparency, high elasticity, and excellent self-restoring force.
