However, it is extremely difficult to design a makeup cosmetic that satisfies these requirements, and it has not yet been commercially available.

As a result of intensive research in view of the current situation, the present inventors found that the essential components of the oil base material are lactic acid nistert, a saturated side chain alcohol, triglyceride, a saturated fatty acid having 8 to 10 carbon atoms, squalane, and cholesterin stearate. It was discovered that when used together, the above-mentioned effects can be achieved due to synergistic effects, and the present invention has been completed.

That is, the present invention is characterized in that a lactic acid ester of a saturated side chain alcohol, a triglyceride of a saturated fatty acid having 8 to 10 carbon atoms, squalane, cholestearin stearate, and a pigment are blended as essential components. It is a non-aqueous makeup amplifier cosmetic.

The lactic acid ester of a saturated side chain alcohol in the present invention is preferably a lactic acid ester of a saturated side chain alcohol having 3 to 2 carbon atoms. For example, inglovir lactate, inbutyl lactate, 2-ethylhexyl lactate, octyldodecyl Lactate, isononyl lactate, 2-hexyldecyl lactate, instearyl lactate, intridecyl lactate, 2-hebutyl undecyl lactate, 5,7.7-6-trimethyl-2-(1,3,5-)limethylbutyl )
-Octyl lactate and the like are preferred.

The lactic acid esters of saturated side chain alcohols are used alone or in combination of two or more, and the blending amount is 6.0 to 90.0% by weight based on the total amount of the oily base material in the formulation.
Preferably it is 30 to 60% by weight.

Examples of triglycerides of saturated fatty acids having 8 to 10 carbon atoms in the present invention include triglyceryl caprylate, triglyceryl pelargonate, triglyceryl caprylate, and triglyceryl caprylate. Examples include acid) glycerylite and the like.

These triglycerides are used singly or in combination, and the blending amount is 6.0 to 90.0% by weight, preferably 60 to 60% by weight, based on the total amount of oily base material in the formulation. .

The amount of squalane blended is 3.0 to 90.0% by weight, preferably 4 to 5.0 to 30% by weight, based on the total amount of oily base material in the formulation.

The amount of cholesterin stearate blended is 1.0 to 20.0% by weight, preferably 5.0 to 10.0% by weight, based on the total amount of oily base material in the formulation.

In addition, the total amount of oily base materials in the above formulation refers to the total amount of oily base materials blended in the makeup cosmetic when the above-mentioned lactic acid ester, triglyceride, squalane, and cholesterin stearate are surrounded. means the total amount,
In addition, the oil-based base material may be a combination of the above-mentioned enclosure and other conventional oil-based base materials (
When used together, it means the total amount of them.

If necessary, use together with the oil-based base material of the above-mentioned enclosure (blending)

The useful and remarkable effects are due to the synergistic effect of the surrounding oily substances.

Its uniqueness is remarkable.

The present invention will be explained in detail below.

Note that the parts shown in the examples are parts by weight.

The sensory tests for make-up cosmetics and their evaluation methods are as follows.

○Sensory test 50 girls (25 in Hokkaido, 25 in Okinawa) between the ages of 18 and 45 tried it for four months (February to May).

○Results of sensory test (evaluation) The results of the sensory test are calculated by summing up the evaluation scores according to Table 1.
The average score is displayed.

Table 1 Note: Changes over time are the results 6 hours after application. Example 1 (oil-based foundation) Red iron oxide 1.4 parts, yellow iron oxide 4 parts, black iron oxide 0.4 parts,
After uniformly mixing 20 parts of titanium oxide, 10 parts of mica, and 3 parts of talc, this pigment mixture was added with 3 parts of microcrystalline wax, 5 parts of sevinyl wax, 3 parts of ganderilla wax, and 1 part of carnauba wax. , 5 parts petrolatum, 8.7 parts liquid paraffin, 18 parts cholesterin stearate, 10 parts.

A molten homogeneous mixture of an oily base consisting of 5 parts of Stuff 9F, 10 parts of imbrovir lactate, and 10 parts of triglyceryl verarbinate was added to obtain a gel.

As a result of the sensory test of this oil-based foundation as described above, the average evaluation score was 92.3 for elongation, 96.5 for fit, 94.2 for touch, 90.1 for force-ring, and average overall evaluation. The score was 95, all of which were extremely good.Furthermore, the feeling of stickiness/unnaturalness after application was 96.2, the color fading over time was 95.8, and the makeup discoloration was 94.
．． 5. The feeling of flatness and discomfort over time was 100, and neither was observed at all.

As described above, the oil-based foundation of the present invention is extremely superior.

Comparative Example 1 (When cholesterin stearate is not used in combination) A control (comparison) oil-based foundation was made by ALS in the same manner except that cholesterin stearate was not blended and 18.7 parts of liquid paraffin was blended. . The average evaluation score of the obtained oil-based foundation was 95 for elongation.
, fit is 65.2, touch is 69.2%, coverage is 72. The sticky feeling after application-unnatural feeling was 80.4, and the color fading over time was 58.5. Makeup deterioration: 70.0
Feeling of discomfort/unnaturalness is 67.2, average overall evaluation score is 71
．． It was 9.

In this way, foundations that do not use 1tF (1 cholesterin stearate) have poor fit and touch,
If the color fades over time, it will cause makeup to fade and give a greasy or strange feeling, which is not desirable.

Ratio M Example 2 (When squalane is not used together) A control oil-based foundation was prepared in the same manner as in Example 1, except that squalane was not blended and 16.7 parts of liquid paraffin was blended.

The average evaluation score of the obtained oil-based foundation was 91 for elongation and 8. Fit: 94.7 - Touch: 65.4
゜Covering is 88.5. Sticky feeling after heavy cloth
The discomfort was 70, the color fading over time was d5.2, makeup fading was 88.9, the feeling of flatness and discomfort over time was 74.8, and the average overall evaluation score was 82.4.

If you use squalane in combination with this type of fan, it will be difficult to touch and give a sticky or strange feeling.
I don't like it.

Comparative Example 1 (without using lactate) A control oil-based foundation was prepared in the same manner as in Example 1, except that 1'-sopropyl lactate was not blended and 18.7 parts of isopropyl palmitate was used. did. The average evaluation scores for the oil-based foundations were: 91.4 for spread, 69.2 for fit, 65.8 for touch, 84.4 for cover/ring, and 9 for sticky/unnatural feeling after application.
, 5. Color fading over time was 74.6, make-up fading was 65.4, feeling of flatness/unnaturalness over time was 70.2, and average overall evaluation score was 77.

In this way, the foundation and Silon that do not contain the above-mentioned lactate (isopropyl lactate) have a poor fit and touch, cause discoloration and makeup deterioration over time, and give a dull or strange feeling. Undesirable.

Comparative Example 4 (When the above-mentioned triglyceride is not used in combination) The same procedure as in Example 1 was carried out except that triglyceryl pelargonate was not blended and 18.7 parts of liquid paraffin was blended, and 1 liter of control oil-based fan boots was prepared. 1SilJa. The average evaluation score of the obtained oil-based foundation was 95 for elongation and 5. Fit is 69.5, touch is 65
．． 2. Covering is 81.8. Smooth feeling/unnatural feeling is 95. 75.7 for discoloration over time, 5 for fading of makeup
8.8, the feeling of stiffness/unnaturalness over time was 75.2, and the average overall evaluation score was 76.7. In this way, the oil-based foundation that does not contain the above triglyceride,
It is undesirable because it has a poor fit and touch, causes discoloration and makeup fading over time, and gives a flat and strange feeling.

Comparative Example 5 (In the case where the oily substance of the above-mentioned surround in the present invention is not blended) The surround of cholesterin star L/-)-squaun, ear fat and triglyceryl velargonate was blended. and liquid paraffin at 43.
A control oil-based foundation was prepared in the same manner as in Example 1, except that 7 parts were added. The average evaluation score of the obtained oil-based foundation was 95.5 for elongation, 51.2° for fit, 42.5 for touch, and 43 for coverage.
．． 8. Stickiness/unnatural feeling after application: 68.8, color fading over time: 42.5, makeup (-1'): 38.8, dull/unnatural feeling over time: 62.1 , with an average overall score of 5. Oil-based foundations that do not contain the above-mentioned triglyceride surrounds have poor fit, touch, and coverage, feel sticky and strange, and can cause the color to fade and makeup to fade over time. This is not good for women, as it gives a feeling of stickiness or discomfort over time.

Example 2 (Cage type foundation) (2) Manufacturing method ■ The pigments of the above prescription ingredients are mixed and passed through a pulverizer for the first time.

(2) Separately, mix the remaining oily substance (oily base material), preservative, and 1st pigment, and add the homogenized mixture to the pigment mixture, mix, and rub evenly. After pulverizing this to a uniform particle size, it is compressed into whole blood.

(3) Performance of K-4M Foundation Through the above-mentioned sensory test (same as Example 1), we investigated its performance and practicality. The results are shown in Table 5 below.

(1) The cake-type foundation wrapper of the present invention spreads similarly to Example 1 (the present invention), has extremely good fit, touch, and coverage, and has a flat and strange feeling after application. It is extremely excellent, with no color fading over time, no makeup smearing, and no unpleasant feeling of flatness.

(2) If cholesterin stearate is not used in combination, the fit, touch, and coverage will be relatively poor, and the color will fade and makeup will fade over time.

A feeling of stiffness and discomfort was observed to a large extent, which was not desirable.

(3) If the above-mentioned lactic acid ester is not used in combination, there is a feeling of fit (C) and the touch is relatively poor.

Unfavorable feeling after application: undesirable feeling (unnatural feeling, fading of color over time, fading of makeup, sticky/unnatural feeling).

(4) If the above triglyceride is not used together.

The fit and touch are relatively poor, and the color fades over time.
Makeup may come off (1D), which is not desirable.

(5) If squalane is not used in combination, the touch is relatively poor, the color fades over time, and there is a considerable feeling of flatness and strangeness, which is not desirable.

(6) If cholesterin stearate, the above lactic acid ester, the above triglyceride and squalane (surroundings) are not blended, the fit (stickiness), the touch is relatively poor, the color fades over time, the makeup smudges, the feeling of stickiness, etc.
It may cause a strange feeling, which is not desirable.
