DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to an oily solid cosmetic which is excellent in gloss, usability, finish, long-lasting and high-temperature stability of a cosmetic film.

[0002]

2. Description of the Related Art Conventionally, oil-based solid cosmetics such as lipstick, eyeshadow, eye cream and the like have difficulty in simultaneously satisfying good gloss of cosmetic film, long-lasting makeup, usability and high-temperature stability of the system. If you want a gloss, glyceride or
This has been dealt with by blending a liquid oil such as an ester type. However, this method has poor makeup durability and tends to cause a sweat on the surface of the cosmetic material in a high temperature state (so-called “sweating” state). However, the lipstick has a drawback that bleeding easily occurs.

[0003]

Accordingly, there has been a demand for the development of an oily solid cosmetic which has good luster, usability, and finish, has long-lasting makeup, and simultaneously satisfies the high-temperature stability of the system.

[0004]

Under these circumstances, the present inventors have conducted intensive studies, and as a result, have found that oil-based solid cosmetics containing polyoxypropylene alkyl ether, and further, that polyoxypropylene alkyl ether and IOB value have been improved. The present inventors have found that an oil-based solid cosmetic blended with a liquid oil of 0.2 or more is excellent in luster, usability, finish, cosmetic durability, and high-temperature stability of the system, and have completed the present invention.

[0005] The polyoxypropylene alkyl ether used in the present invention is not particularly limited as long as it is a viscous liquid or semi-solid at room temperature represented by the following chemical formula. , Polyoxypropylene butyl ether, polyoxypropylene lauryl ether, etc., and commercially available products are Unilube MB370 and MB700 (Nippon Oil & Fats)
Etc.

Wherein R is an alkyl group having 1 to 15 carbon atoms, and n is an integer of 15 to 75.

[0008] One or more of these polyoxypropylene alkyl ethers can be used as necessary. The polyoxypropylene alkyl ether of the present invention accounts for 1 to 20% by weight of the oily solid cosmetic of the present invention.
(Hereinafter, simply indicated by “%”). Within this range, particularly good luster, long-lasting makeup, and high-temperature stability can be obtained.

Further, the IOB value used in the present invention is 0.2
Examples of the above liquid oil include diglyceryl triisostearate, glyceryl trioctanoate, glyceryl tri-2-ethylhexanoate, propylene glycol dicaprate, oleyl alcohol, castor oil, and the like. The above can be used.

Further, in the oil-based solid cosmetic of the present invention, the above polyoxypropylene alkyl ether and IO
The mixing ratio with a liquid oil having a B value of 0.2 or more is 1/80 to 1 /
If it is in the range of 1, gloss, usability, finish, makeup lasting,
High temperature stability is remarkable and more preferable.

The oily solid cosmetic of the present invention contains, in addition to the above components, an oily base for producing an oily solid cosmetic. The oily base includes, for example, solid, semi-solid and liquid oils which are generally used, and is not particularly limited, and includes animal oils, vegetable oils, mineral oils, hydrocarbons, waxes, esters, regardless of synthetic oils.
Fatty acids, higher alcohols, silicone oils, fluorinated oils, surfactants and the like can be mentioned. For example, polybutene, vaseline, paraffin wax, ceresin wax, microcrystalline wax, synthetic hydrocarbon wax, mokuro, beeswax, carnauba wax, candelilla wax, dimethylpolysiloxane, methylphenylpolysiloxane, methylhydrogenpolysiloxane,
A dimethylpolysiloxane polymer having a three-dimensional crosslinked structure can be used, and one or two or more of them can be used as needed, and are appropriately selected depending on the product form.

Further, the oil-based solid cosmetic of the present invention includes, in addition to polyoxypropylene alkyl ether, a liquid oil having an IOB value of 0.2 or more, and the above-mentioned oil-based base, in addition to a range that does not impair the effects of the present invention. Powders, pigments, antioxidants, polymer compounds, fragrances, preservatives, ultraviolet absorbers, humectants, cosmetic ingredients and the like generally used in cosmetics can be blended.

[0013]

BEST MODE FOR CARRYING OUT THE INVENTION The oil-based solid cosmetic of the present invention is not particularly limited in use, but is preferably used for skin, for example,
It is applied to eye shadow, eye cream, etc. The oil-based solid cosmetic of the present invention is substantially free of water,
The manifestation of the effect is remarkable and more preferable.

EXAMPLES The present invention will be described in more detail with reference to the following Examples, but it should not be construed that the present invention is limited thereto. Examples 1-2 and Comparative Examples 1-3 <stick type lipstick>

[0015]

[Table 1]

(Preparation method) Components (1) to (9) are heated to 110 ° C.
After heating and dissolving at 120 ° C., (10) was added, mixed uniformly, poured into a mold for molding, and cooled and solidified to produce a lipstick.

For Examples 1 and 2 and Comparative Examples 1 to 3, gloss, usability (lightness of spreading), finish (uniformity of the decorative film), and long-lasting (hardness of bleeding, long-lasting color) (Goodness, difficulty in color transfer), and the high-temperature stability of the system were evaluated. Table 1 also shows the results. (Test method and evaluation method) a) Gloss of the makeup film Each sample was applied to the lips, and the gloss of the makeup film was visually evaluated. b) Lightness of spreadability (usability) The lightness of spread when applying each sample to the lips was evaluated. c) Uniformity of the makeup film (finish) Each sample was applied to the lips, and the uniformity of the makeup film was evaluated. d) Difficulty of bleeding (make-up) Each sample was applied to the lips, the panel was allowed to live a normal life, and the bleeding after 2 hours was evaluated. e) Good color retention (cosmetic retention) Each sample was applied to the lips, the panel was allowed to live a normal life, and the color retention after half a day was evaluated. f) Difficulty of color transfer (holding makeup) Apply each sample to the lips, let the panel live a normal life, hold the lips with tissue paper after 2 hours and evaluate the difficulty of the color transfer of the lipstick did. g) High-temperature stability of the system Each sample was left in a thermostat at 50 ° C. for 1 hour, and then the state of perspiration on the sample surface was visually evaluated.

For each evaluation item, an absolute evaluation of the following 7 grades (0 to 6) was performed by a sensory test panel of 10 persons.
Further, the average score was evaluated in four stages. (1) Absolute evaluation 6: Very good 5: Good 4: Somewhat good 3: Normal 2: Somewhat bad 1: Bad 0: Very bad (2) Four-point rating 5 or more: ◎ 4 or more and less than 5: ○ 3 or more and less than 4 points: △ Less than 3 points: ×
