Description

The present invention relates to an oil-based solid cosmetic containing a specific polyurethane gel composition, an oil-based gelling agent and a spherical powder. Regarding oil-based solid cosmetics that have excellent durability.

One of the features of oil-based solid cosmetics is that they are composed mainly of oil and can be made into various shapes by using a component that gels oil such as an oil-based gelling agent. Due to its characteristics, it not only enjoys the aesthetic appearance and the characteristic shape, but also the appearance, and it is widely used for eye color, cheeks, lipsticks, etc. Further, since oil-based solid cosmetics are made by gelling oil, quality such as smooth spreading and non-stickiness has been required.

On the other hand, due to the recent make-up trends and diversification of usage scenes, it is required to create a uniform and long-lasting makeup film with a soft focus effect in addition to the characteristics of conventional oil-based solid cosmetics. However, since oil-based solid cosmetics contain oil as the main component, the uniformity of the cosmetic film and the long-lasting makeup when the powder is contained may be inferior to the solid powder cosmetics, and the oil-based solid cosmetics have a soft focus effect. Various studies have been made on cosmetics. For example, 3% by weight to 15% by weight of at least one lipophilic gelling agent and a second filler different from at least 5% by weight of the first filler and at least 5% by weight of the first filler. An anhydrous composition comprising 10% by weight to 50% by weight of a filler and 40% by weight to 85% by weight of at least one fatty phase, wherein the amount by weight is the total weight of the composition. In contrast, the composition of the first filler and the second filler is selected from spherical cellulose particles, powders of N-acyl amino acids having C8-C22 acyl groups, polyamide particles and spherical porous silica particles. Depending on the material, there are compositions having an excellent soft focus effect. (See Patent Document 1)

Further, in oil-based solid cosmetics, techniques related to makeup retention are also being studied. For example, (A) (a1) powder containing titanium oxide is 40% by mass or more and 60% by mass or less based on the total amount of cosmetics, (B) film forming agent, (C) volatile oil agent, (D) 25 ° C. An oily solid cosmetic containing 2% by mass or more and 12% by mass or less based on the total amount of cosmetics has been proposed (see Patent Document 2).

However, if the technique of Patent Document 1 is used to obtain a soft focus effect, it may not be possible to obtain a quality that is satisfactory for the uniformity of the cosmetic film and the long-lasting makeup, and in order to obtain an excellent long-lasting makeup, Patent Document 2 When the above technique is used, the weight may be felt at the time of application, and it may not be possible to obtain satisfactory quality for spreading and spreading. Furthermore, it was difficult to obtain a uniform cosmetic film when the spread and spread were not satisfactory. Further, by using the techniques of Patent Documents 1 and 2 in combination, a cosmetic having an excellent soft focus effect and long-lasting makeup can be obtained, but the ease of application, which feels heavy at the time of application, cannot be sufficiently obtained and is smooth. It was difficult to obtain satisfactory quality for the spread and spread. Therefore, it is an object of the present invention to provide an oil-based solid cosmetic film that realizes a soft focus effect, a uniform and highly durable cosmetic film, and a quality that spreads smoothly.

As a result of diligent studies in view of the above circumstances, the present inventors have obtained smooth spread and spread, uniformity of the cosmetic film, and soft focus effect in the oil-based solid cosmetics containing the oil-based gelling agent and the spherical powder. However, the effect was not sufficiently satisfactory, and further improvement in makeup retention was required. Therefore, while examining various components, we focused on polyurethane, which has a hydrophilic part and a hydrophobic part and has improved cosmetic retention when combined with an oil-based gelling agent. In particular, it has been found that when it is contained in an oil-based solid cosmetic as a gel composition containing an oil agent and a polyurethane having a specific structure, it is particularly excellent in soft focus effect and long-lasting makeup. Furthermore, by containing phenyl-modified silicone, smooth spreading and spreading and uniformity of the decorative film can be further enhanced, and among phenyl-modified silicones, diphenylsiloxyphenyltrimethicone can be used to obtain a higher effect. I found it. Furthermore, they have found that the effect of the present application can be further improved by setting the polyurethane gel composition and the spherical powder in a specific ratio, and have completed the present invention.

It shall mean.

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).

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 resilience. 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.

(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.

The silicone gel of Production Comparative Example 1 lacks gloss and lacks restoring force. The polysaccharide gel of Production Comparative Example 2 has weak resilience and restoring power. The wax oil gel of Production Comparative Example 3 lacks gloss.

[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 diluted with cetyl 2-ethylhexanoate so that the pure content becomes 10.5% by mass, heated at 85 ° C., poured into a jar, and cooled to 30 ° C. to make it elastic. 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 there was 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.

As is clear from the results in Tables 2 and 3, good results were obtained in all the evaluation items in Examples 1 to 15 as compared with Comparative Examples.
On the other hand, Comparative Example 1 containing no component (A) lacks the flexibility of the cosmetic film, so that the uneven portion of the skin becomes twisted with the passage of time, and the applied portion cannot be uniformly blurred. The unevenness has been emphasized. That is, satisfactory quality was not obtained for the soft focus effect, the longevity of the makeup, and the uniformity of the makeup film. In addition, Comparative Example 2 in which a (vinyldimethicone / lauryldimethicone) crosspolymer polymer was used instead of the component (A) did not provide satisfactory quality for long-lasting makeup. Further, in Comparative Example 3 containing no component (C), rolling on the skin peculiar to the spherical powder was not felt, and satisfactory quality could not be obtained for smooth spreading and spreading. In Comparative Example 4 in which talc was used instead of the component (C), the cosmetic film derived from the amorphous powder had a tight finger stop, the cosmetic film became uneven, and the smooth spread and spread and the uniformity of the cosmetic film were satisfied. I couldn't get the quality. Further, in Comparative Example 5 which does not contain the component (B), since the oily gelling agent of the present invention is not contained, the oily solid state of the present invention cannot be obtained, and the quality satisfying the effect of the present application can be obtained. I couldn't.
