Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a gel cosmetic,
More specifically, the present invention relates to a gel cosmetic which has a light spread, does not have a sticky feeling upon application, and is excellent in freshness and makeup retention after application.

[0002]

2. Description of the Related Art Silicone oil has a light feel and a refreshing feel, so that it can be used in makeup cosmetics,
It is used in various cosmetics such as hair cosmetics and quasi drugs. In particular, gel cosmetics are used in liquid foundations, sunscreen gels, moisture creams, hair gels, antiperspirant creams and the like. Examples of the gel composition containing silicone oil include a gel composition containing 100 parts by weight of silicone oil and 2 to 30 parts by weight of dextrin fatty acid ester (Japanese Patent Publication No. 3-6179), and an organohydrogenpolysiloxane crosslinked polymer. And a gel-like composition comprising a low-viscosity silicone oil and a cosmetic composition containing the same (Japanese Patent Laid-Open No. Sho 63-63)
No. -152308) has been proposed. However, these conventional silicone oil-containing gel cosmetics have a problem that the stability with time is poor and the silicone oil is separated. In order to solve such a problem, a gel composition obtained by mixing silicone oil with one or more polyoxyalkylene-modified organopolysiloxane, an organically modified montmorillonite clay mineral and water (Japanese Patent Publication No.
19269) has been proposed. However, this gel composition has a problem in that it lacks refreshing properties and makeup retention after being applied to the skin.

[0003]

In view of the above circumstances, the present inventors have proposed a silicone-containing gel cosmetic composition which is light in spreadability, has no sticky feeling during application, and is excellent in freshness and longevity after application. As a result of earnest research,
It has been found that this problem can be solved by blending a specific silicone compound and a hydrophobized powder, and has completed the present invention.

[0004]

That is, the present invention is as follows.
(I) one or more silicone oils, (ii) one or more polyether modified silicones represented by the following general formula 2, (iii) water, (iv) one or two hydrophobized powders It is a gel cosmetic containing at least one kind.

The silicone oil used in the present invention is not particularly limited, but specifically, it has a low viscosity such as dimethylpolysiloxane, methylphenylpolysiloxane, dimethylpolysiloxane / methylphenylpolysiloxane copolymer and the like. To high viscosity diorganopolysiloxanes; cyclic siloxanes such as octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane, tetramethyltetraphenyltetracyclosiloxane; high degree of polymerization gum-like dimethylpolysiloxane, gum-like dimethylsiloxane. Examples include methylphenylsiloxane copolymer, cyclic siloxane solution of gum-like dimethylpolysiloxane; trimethylsiloxysilicic acid and the like, cyclic siloxane solution of trimethylsiloxysilicic acid, and the like, further having 6 to 6 carbon atoms.
A diorganopolysiloxane having 50 alkyl groups,
Examples include amino-modified silicone, higher alkoxy-modified silicone, higher fatty acid-modified silicone, alkyl-modified silicone, fluorine-modified silicone and the like. Among these, the gel cosmetics have high stability when cyclic polysiloxanes, particularly cyclic dimethyl polysiloxanes are used.

In the gel cosmetic of the present invention, the blending amount of silicone oil is not particularly limited, but is preferably 80% by weight or less.

The polyether-modified silicone used in the present invention is the polyoxyalkylene group-containing organopolysiloxane represented by the general formula (2).
Specific examples of the acyl group represented by R ^′ include a formyl group, an acetyl group, a propionyl group, a butyryl group, an acryloyl group, a benzoyl group, and a toluoyl group. Specific examples of the alkyl group having 1 to 4 carbon atoms include: Are exemplified by a methyl group, an ethyl group, an i-propyl group, an n-propyl group, a t-butyl group and an n-butyl group.

In the polyoxyalkylene group,
When a or b is less than 5, the polyether-modified silicone does not show a sufficient thickening effect, and when a or b exceeds 50, the obtained gel cosmetic has a sticky feeling. Like Further, the content of the polyoxyalkylene group is not particularly limited, but the content of the polyoxyalkylene group is 20 to 70% by weight (however, 2
0% by weight is not included). this is,
This is because when the content of the polyoxyalkylene group is 20% by weight or less, the thickening effect of the polyether-modified silicone is significantly reduced, and when it exceeds 70% by weight, the compatibility with silicone oil is low. This is because it will decrease.

Further, m is an integer of 50 to 1000,
n is an integer of 1 to 40, and preferably m is 200 to
600 and n are 5-20. This is because when m is less than 50 and n is less than 1, the thickening effect is insufficient, and when m is more than 1000 and n is more than 40, the gel obtained is This is because the cosmetic cosmetics have a sticky feeling.

The molecular weight of the polyether-modified silicone used in the present invention is not particularly limited.
Although the viscosity at 0 ° C. is not particularly limited, the viscosity when the polyether-modified silicone used in the present invention is a 50 wt% solution of octamethyltetrasiloxane because it forms a particularly stable gel and has a dry feel. Is preferably in the range of 1000 to 100000 cst.

The amount of the polyether modified silicone used in the present invention is 2 to 30% by weight, preferably 5 to 15% by weight. This is because in the gel cosmetic of the present invention, if the amount of the polyether-modified silicone is less than 2% by weight, a stable gel cosmetic cannot be obtained, and if it exceeds 30% by weight. This is because the gel cosmetic has a sticky feeling.

The amount of water used in the present invention is preferably 0.2 to 80% by weight, and most preferably 2 to 6% by weight based on the total amount of the cosmetic. When the content of water is 0.2% by weight or less, a stable gel-like cosmetic cannot be obtained, and when it exceeds 80% by weight, water is separated from the gel-like cosmetic and a stable gel-like cosmetic is obtained. This is because cosmetics cannot be obtained.

The hydrophobized powder used in the present invention is not particularly limited, but fatty acid dextrin treated powder, trimethylsiloxysilicic acid treated powder, fluorine modified trimethylsiloxysilicic acid treated powder, methylphenylsiloxysilicic acid treated powder, fluorine modified.

Among these hydrophobized powders, those obtained by hydrophobizing silicic acid anhydride are preferable, and among the hydrophobized powders, dimethylsilylated silicic anhydride and trimethylchlorosilane obtained by treating with dimethylchlorosilane or dimethyldialkoxysilane. Silane, trimethylalkoxysilane, and trimethylsilylated silicic acid anhydride obtained by treatment with hexamethyldisilazane are the most effective in terms of improving stickiness and keeping makeup.

The amount of the hydrophobized powder used in the present invention is not particularly limited, but is preferably 1 to 60% by weight, more preferably 10 to 50% by weight, based on the total amount of the cosmetic of the present invention.
