Description

The present disclosure relates to solid cosmetic compositions.

One example of solid cosmetics is lipstick. There are various types of lipstick, depending on the user's taste and fashion, ranging from lustrous lipstick to matte lipstick.

For example, Patent Literature 1 describes a matte lipstick cosmetic. The stick-shaped lipstick cosmetic described in Patent Document 1 contains 20 to 50% by weight of powder and 20 to 50% by weight of chain dimethylpolysiloxane having a viscosity of 5 to 8 cs, and candelilla wax is used as a polar wax. , containing 25 to 30% by weight of kaolin as an extender.

Japanese Patent Publication No. 7-20850

The following analysis is given in light of this disclosure.

In order to make the lipstick applied to the lips look matte, it is generally necessary to increase the content of powders other than color pigments, as in the stick-type lipstick cosmetic described in Patent Document 1, or to solidify the lipstick. For example, the content of the agent is increased. However, if the content of the powder other than the coloring pigment and the solidifying agent is increased, the smooth feeling of application is lost.

Therefore, there is a demand for a solid cosmetic composition that achieves both a smooth application feel and a matte feel.

A first aspect of the present disclosure provides a solid cosmetic composition containing (A) a nonpolar wax having a melting point of 80° C. or higher, (B) a polar wax, and (C) a liquid oil. The total amount of non-polar wax and polar wax is 23% by mass to 40% by mass based on the mass of the cosmetic composition. The polar wax is 20% to 60% by weight with respect to the total amount of non-polar wax and polar wax. The non-coloring pigment is 15% by mass or less based on the mass of the cosmetic composition. A mixture obtained by melting and mixing a non-polar wax, a polar wax, and a liquid oil and then solidifying it is defined as a first mixture, and a mixture obtained by melting and mixing a non-polar wax and a liquid oil and then solidifying is defined as a second mixture. When the type and content of liquid oil are the same in the mixture of and the second mixture, and the mass ratio of the non-polar wax and the polar wax in the first mixture is 3: 2, the first mixture at 30 ° C. The penetration hardness is lower than the penetration hardness at 30° C. of the second mixture.

According to the oil-based solid cosmetic composition of the present disclosure, it is possible to give a matte feeling to the application area. In addition, it is possible to realize a smooth application feeling while giving a matte feeling.

In the following description, POE is an abbreviation for polyoxyethylene, POP is an abbreviation for polyoxypropylene, and the number in parentheses after POE or POP represents the average added mole number of POE or POP groups in the compound.

In the present disclosure, the term "substantial amount" refers to an amount that can produce an effect by adding the compound.

A solid cosmetic composition according to a first embodiment of the present disclosure will be described.

In the present disclosure, "solid" refers to a substance that can maintain a solid state at 25°C under atmospheric pressure. In the present disclosure, the term “liquid” means fluidity at 25° C. under atmospheric pressure.

The solid cosmetic composition of the present disclosure includes (A) nonpolar wax, (B) polar wax, and (C) liquid oil.

[(A) non-polar wax]
Apolar waxes can be, for example, hydrocarbon waxes having branched chains. Examples of such hydrocarbon wax include microcrystalline wax and polyethylene wax. The non-polar wax can be a mixture of two or more non-polar waxes. A non-polar wax can be, for example, a mixture of microcrystalline wax and polyethylene wax.

The non-polar wax preferably has a melting point of 80° C. or higher. If the melting point of the non-polar wax is less than 80°C, it is not possible to obtain a matt feeling when the solid cosmetic is applied. The melting point of the non-polar wax can be 100° C. or lower. If the non-polar wax is a mixture, the melting point given above is the melting point of the mixture. The melting point of wax can be measured using a differential scanning calorimeter (DSC).

The non-polar wax can be 5% by mass or more, 8% by mass or more, 10% by mass or more, 12% by mass or more, or 15% by mass or more with respect to the mass of the solid cosmetic composition. The non-polar wax can be 35% by mass or less, 30% by mass or less, 25% by mass or less, 20% by mass or less, or 15% by mass or less with respect to the mass of the solid cosmetic composition.

[(B) Polar wax]
A polar wax can be, for example, a wax other than a hydrocarbon wax.

Preferably, the polar wax can reduce the hardness of the non-polar wax when mixed with the non-polar wax. For example, the first mixture is a mixture obtained by melting and mixing a nonpolar wax, a polar wax, and a liquid oil and then solidifying the mixture. A second mixture is obtained by melting and mixing the non-polar wax and the liquid oil and then solidifying the mixture. The non-polar wax is the component (A) described above. The mass ratio of the total amount of the non-polar wax and the polar wax in the first mixture is the same as the mass ratio of the non-polar wax in the second mixture. The mass proportion can be, for example, 25% by mass with respect to the mass of the mixture. It is assumed that the first mixture and the second mixture have the same type and content of liquid oil. Liquid oil is, for example, component (C) described later. The mass ratio of non-polar wax to polar wax in the first mixture is non-polar wax:polar wax=3:2. The hardness of the first mixture and the second mixture is measured using a rheometer at a pressure-sensitive axis of 1φ, a penetration speed of 2 cm/min, a penetration of 10 mm, and 30°C. The polar waxes are preferably selected such that the penetration hardness at 30° C. of the first mixture is lower than the penetration hardness at 30° C. of the second mixture.

The polar wax can be, for example, at least one selected from the group consisting of beeswax, Japanese wax, hydrogenated castor oil, and sucrose triacetate tetrastearate.

Candelilla wax is 5% by mass or less, preferably 3% by mass or less, more preferably 2% by mass or less, more preferably 1% by mass or less, more preferably 0% by mass, based on the mass of the solid cosmetic composition. is preferable. If it contains a lot of candelilla wax, it will lose its smooth application feeling.

The melting point of the polar wax is preferably 45° C. or higher. When the melting point of the polar wax is less than 45°C, it becomes difficult to give a matte feeling to the coated area. The melting point of the polar wax is preferably 90° C. or lower. If the melting point of the polar wax exceeds 90° C., it becomes difficult to obtain a smooth application feeling.

The polar wax can be, for example, 2% by mass or more, 5% by mass or more, 8% by mass or more, 10% by mass or more, or 12% by mass or more with respect to the mass of the solid cosmetic composition. The polar wax is, for example, 30% by mass or less, 25% by mass or less, 22% by mass or less, 20% by mass or less, 18% by mass or less, 15% by mass or less, or 12% by mass with respect to the mass of the solid cosmetic composition. % or less.

The total amount of non-polar wax and polar wax is preferably 23% by mass or more relative to the mass of the cosmetic composition. The total amount of non-polar wax and polar wax can be, for example, 25% by mass or more, 27% by mass or more, or 30% by mass or more relative to the mass of the cosmetic composition. If the total amount of the non-polar wax and the polar wax is less than 23% by mass, the coated area cannot have a matte feel, and the hardness is insufficient, making it impossible to mold. The total amount of non-polar wax and polar wax is preferably 40% by mass or less with respect to the mass of the cosmetic composition. The total amount of nonpolar wax and polar wax can be, for example, 35% by mass or less, 30% by mass or less, or 27% by mass or less based on the mass of the cosmetic composition. If the total amount of the non-polar wax and the polar wax exceeds 40% by mass, the smooth feeling of application is lost.

The polar wax is preferably 20% by mass or more with respect to the total amount of the non-polar wax and the polar wax. The polar wax can be, for example, 25% by mass or more, 30% by mass or more, or 35% by mass or more with respect to the total amount of the non-polar wax and the polar wax. If the polar wax is less than 20% by mass with respect to the total amount of the non-polar wax and the polar wax, smoothness during application cannot be obtained. The polar wax is preferably 60% by mass or less with respect to the total amount of the non-polar wax and the polar wax. The polar wax can be 55% by mass or less, 50% by mass or less, 45% by mass or less, or 40% by mass or less with respect to the total amount of the non-polar wax and the polar wax. If the polar wax exceeds 60% by mass based on the total amount of the non-polar wax and the polar wax, it becomes difficult to give a matte feeling to the application area, and the solid cosmetic composition tends to break during application.

According to the solid cosmetic composition of the present disclosure, it is possible to give a matte feeling to the area to which the solid cosmetic composition of the present disclosure is applied without giving gloss. In addition, even with a cosmetic composition that can give a matte feel, a smooth feeling of application can be obtained without giving a heavy feeling of application.

The solid cosmetic composition of the present disclosure can be applied to, for example, lipstick, lip balm, base makeup, foundation, and the like.

The solid cosmetic composition of the present disclosure will be described below with examples. However, the solid cosmetic composition of the present disclosure is not limited to the following examples. The unit of the content of each component shown in each table is % by mass.

[Test Examples 1 to 37]
A stick-shaped solid cosmetic was prepared. For each solid cosmetic, hardness was measured, and the presence or absence of matte feeling and smoothness during application were evaluated. The evaluation method and evaluation criteria for each test item are shown below.

Evaluation 1: Hardness Hardness is a value obtained by measuring a sample left at 30° C. for 1 hour using a rheometer manufactured by Rheotech, with a pressure-sensitive axis of 1φ, a penetration speed of 2 cm/min, and a penetration of 10 mm. do.

Evaluation 2: Matte feeling and smoothness of spread during application For each sample, a use test was conducted by 10 expert panels, and the matte texture of the finish when applied (indicated as “matte feeling” in the table) and the application The smoothness of spreading over time (indicated as "smoothness at the time of application" in the table) was evaluated in the following 5 stages, scored, and evaluated by calculating the average value.

[Matte feeling]
5: Matte finish;
4: Slightly matte finish;
3: Neither matte nor glossy;
2: It has a slightly glossy finish;
1: Glossy finish.

[Smoothness when applied]
5: very smooth;
4: Slightly smooth;
3: Neutral;
2: not smooth;
1: Not smooth at all.

(Evaluation criteria)
A: Average score of 4.5 or more B: Average score of 3.5 or more and less than 4.5 C: Average score of 2.5 or more and less than 3.5 D: Average score of 1.5 or more Less than 2.5 points E: Average score less than 1.5 points

[Test Examples 1 to 24]
Solid cosmetics were prepared by changing the types and amounts of the non-polar wax and the polar wax, with the total amount of wax set to 25% by mass. Tables 1 to 5 show the composition and evaluation of each solid cosmetic. FIG. 1 shows a graph showing the relationship between the polar wax content and the hardness of the composition in Test Examples 1-20.

Smoothness was not obtained in Test Example 24, which did not contain the polar wax of component (B). In Test Example 23, in which the amount of the non-polar wax of component (A) was reduced and the amount of liquid oil was increased as compared with Test Example 24, the smoothness could be improved, but the matte feeling could not be obtained.

In Test Examples 1 to 20, at least part of component (A) in Test Example 24 was replaced with polar wax. In Test Examples 6 to 20 using candelilla wax, carnauba wax, and rice bran wax as polar waxes, the matte feeling could be improved more than in Test Example 25, but the hardness was also increased, and smoothness could not be obtained. could not. In addition, it was observed that the higher the polar wax content, the higher the hardness. On the other hand, in Test Examples 1 to 3 using beeswax corresponding to the component (B), the matte feeling could be enhanced, the hardness could be lowered, and smoothness could be obtained. Moreover, unlike Test Examples 6 to 20, it was confirmed that the hardness tends to decrease as the beeswax content increases. In Test Examples 4 and 5, the hardness decreased and the matte feeling decreased. From this, when the beeswax is 20 to 60% (= mass of (B) / {mass of (A) + mass of (B)} × 100) in the total amount of wax, both matte feeling and smoothness can be achieved. it is conceivable that.

In Test Example 21, in which petroleum jelly having a melting point of 48 to 60° C., which is a non-polar semi-solid oil, was used as a part of component (A) instead of component (B), no matte feeling was obtained. Similarly, in Test Example 22, in which dimer dilinoleic acid (phytosteryl/behenyl), which is a polar semi-solid oil and has a melting point of 33 to 34° C., was used instead of the component (B), no matte feeling was obtained. rice field. As a result, it is considered that a polar wax is necessary in order to increase the matte feeling and obtain a smooth application feeling by means of an oily component without using a powder raw material.

Looking at FIG. 1, when the total amount of non-polar wax and polar wax is kept constant, the hardness of the solid cosmetic tends to stay the same or increase as the content of candelilla wax, carnauba wax, and rice bran wax increases. On the other hand, when the content of beeswax increases, the hardness of the solid cosmetic composition tends to decrease. For example, when comparing Test Examples 2, 7, 12 and 17 in which the mass ratio of non-polar wax to polar wax is 3:2, Test Example 2 using beeswax is the only test example in which polar wax is not added. It is lower than the hardness of 25. Therefore, it is preferable that the polar wax, when mixed with the non-polar wax, lowers the hardness of the mixture of the polar wax and the non-polar wax more than the hardness of the non-polar wax alone. In Test Examples 1 to 20, the solid cosmetics also contained non-polar waxes and components other than polar waxes, but the types and content rates were the same. It does not seem to affect the change.

[Test Examples 25 to 31]
The same tests as in Test Examples 1-24 were conducted with the total amount of wax reduced from that in Test Examples 1-24. Table 6 shows the composition and evaluation of each solid cosmetic.

In Test Examples 25 and 26, in which the total amount of wax was 20% by mass, a sufficient matte feeling could not be obtained. Moreover, in Test Examples 27 and 28, the hardness was too low, and it was impossible to form into a stick shape. In Test Examples 29 to 31, in which the total amount of wax was 15% by mass, the hardness was too low, and it was impossible to form a stick shape. From this, it is considered that the total amount of wax is preferably 23% by mass or more.

[Test Examples 32 to 37]
The same tests as in Test Examples 1 to 24 were performed by changing the type of component (B). Table 7 shows the composition and evaluation of each solid cosmetic.

When Japanese wax, hydrogenated castor oil and sucrose triacetate tetrastearate were used as the component (B), both matte feeling and smoothness could be achieved. However, the use of myristyl myristate, jojoba esters and hydroxystearic acid resulted in high hardness and lubricity could not be achieved.
