Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a sunscreen cosmetic, and more particularly to a sunscreen cosmetic excellent in usability.

[0002]

BACKGROUND OF THE INVENTION Since sunscreen cosmetics are used on the whole body, they have poor spreadability.
There was a problem that it was difficult to apply because of its usability such as being light and not sticky. Conventionally, in order to improve this usability, low molecular weight silicones have been used in sunscreen cosmetics. However, only by blending the silicone oil, it has not been possible to completely satisfy the feeling of use such as the spreadability and the freshness as a sunscreen cosmetic.

[0003]

Means for Solving the Problems The inventors of the present invention have made earnest studies as to whether or not it is possible to further improve the feeling of use of sunscreen cosmetics, and as a result, as a base using a specific silicone compound, an ultraviolet absorber and It was found that a sunscreen cosmetic having good spreadability and excellent usability can be obtained by adding an ester oil, and the present invention has been completed.

That is, the present invention comprises (i) one or more silicone oils, (ii) one or more polyether-modified silicones represented by the following general formula (1), and (iii) ultraviolet rays. One or more absorbents, (iv)
A sunscreen cosmetic comprising one or more ester oils.

[Wherein A is a methyl group, a phenyl group and the general formula: -C ₃ H ₆ O (C ₂ H ₄ O) a (C ₃ H ₆ O) bR '.
(Wherein R ′ represents a hydrogen atom, an acyl group, and
A group selected from the group consisting of 4 alkyl groups,
Is an integer of 5 to 50, and b is an integer of 5 to 50. ) Is a group selected from the group consisting of polyoxyalkylene groups, R is a methyl group or a phenyl group, m is an integer of 50 to 1000, and n is 1 to 4
It is an integer of 0. However, at least one has a polyoxyalkylene group in the molecule. ]

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 diorganopolysiloxane, octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane, tetramethyltetraphenyltetracyclosiloxane, and other cyclic siloxanes; high degree of polymerization gum-like dimethylpolysiloxane, gum-like dimethylsiloxane. Examples include methylphenylsiloxane copolymers, gum-like dimethylpolysiloxane cyclic siloxane solutions; trimethylsiloxysilicic acid and the like, trimethylsiloxysilicic acid cyclic siloxane solutions, and the like, with 6 to 50 carbon atoms.
Examples thereof include diorganopolysiloxane having an alkyl group, amino-modified silicone, higher alkoxy-modified silicone, higher fatty acid-modified silicone, alkyl-modified silicone, fluorine-modified silicone and the like. The silicone oil is used as a solvent for the polyether-modified silicone, and its compounding amount is an appropriate amount as a solvent for the polyether-modified silicone.

Further, the polyether-modified silicone used in the present invention is an organopolysiloxane having a polyoxyalkylene group represented by the above general formula (1). As the acyl group of R ′, specifically, a formyl group,
Examples thereof include 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 a methyl group,
Examples thereof include an ethyl group, i-propyl group, n-propyl group, t-butyl group and 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 a
Alternatively, when b exceeds 50, the obtained cosmetic has a sticky feeling.

[0010] The content of the polyoxyalkylene group is not particularly limited.
It is desirably about 70% by weight (however, not including 20% by weight). 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 remarkably reduced. This is because the compatibility is reduced.

M is an integer of 50 to 1000;
n is an integer of 1 to 40, and preferably m is 200 to
600, n is 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 obtained makeup is This is because the material becomes sticky.

The molecular weight of the polyether-modified silicone used in the present invention is not particularly limited, and its viscosity at 25 ° C. is not particularly limited, but from the viewpoint of stability and usability, the molecular weight is 50,000 or more, preferably 50.
The viscosity is in the range of 1,000 to 80,000, and the viscosity when the polyether-modified silicone is a 50 wt% solution of octamethyltetrasiloxane is 1000 to 100.
It is preferably in the range of 000 cst. Such a polyether-modified silicone is known as a gelling agent, and is described, for example, in JP-A-5-311076.

The amount of the polyether-modified silicone used in the present invention is 2.0 to 30.0% by weight, preferably 5.0 to 15.0% by weight. This is because in the sunscreen cosmetic of the present invention, the content of the polyether-modified silicone is less than 2.0% by weight,
This is because the stability is poor, and if it exceeds 30.0% by weight, a sticky feeling is obtained.

The amount of the ultraviolet absorber used in the present invention is 0.01 to 40.0% by weight, preferably 0.05 to 2
5.0% by weight. If it is less than 0.01% by weight, the sunscreen effect is poor, and if the compounding amount exceeds 40.0% by weight, the ultraviolet protection effect is not actually required and it is uneconomical.
