Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to cosmetics, and more particularly, to an object of the present invention is to provide a cosmetic which essentially contains a volatile cyclic silicone and is excellent in persistence and stability.

[0002]

2. Description of the Related Art Conventionally, in order to improve the persistence of the cosmetic effect in cosmetics, a resin having a film forming property has been dissolved in a volatile oil agent and blended into the cosmetics. That is, after the application of the cosmetic, with the volatilization of the volatile oil agent, the film-forming resin forms a film to form a continuous film, thereby improving the durability. Resins having a film-forming property are represented by vinyl resins, acrylic resins and modified cellulose resins, and are appropriately selected and used from the viewpoint of hardness, flexibility, water resistance, oil resistance and the like. .
In recent years, organosilicon-based resins have been frequently used,
A silicone resin or an acrylic silicone resin as disclosed in JP-A-2-25411 is blended.

On the other hand, in recent years, cyclic silicones such as octamethylcyclotetrasiloxane and decamethylcyclopentasiloxane have been frequently used as volatile oil agents.
This is because it is superior in safety to skin, hair and nails as compared with low molecular weight volatile hydrocarbons.

[0004]

Although the incorporation of these film-forming resins gives an effect on the improvement of the persistence of the cosmetic effect, it does not improve the stability of the cosmetic itself. As a formulation technology for obtaining long-lasting cosmetic effects, especially improved water resistance and oil resistance (sebum resistance),
It is common practice to use non-aqueous or water-in-oil emulsified cosmetic formulations.However, the dispersion stability or emulsification stability of the coloring material should be based on the viscosity of the dispersion medium, especially the yield value. is important.

However, a gelling agent that imparts viscosity to a volatile cyclic silicone so as to have a yield value is as follows:
Very few types. Although a three-dimensional cross-linked organopolysiloxane as disclosed in Japanese Patent Application Laid-Open No. 1-190757 is effective, the required compounding amount capable of securing the stability is relatively high, and sometimes the volatile oil is volatilized by volatilization. In some cases, the continuity of the formed film was impaired. Therefore, the cosmetic formulation was shaken at the time of use, and no gelling agent was used, or a solid oil was added to increase the apparent viscosity. It was not possible. Therefore, in cosmetics containing a volatile cyclic silicone oil, it has been desired to achieve both improvement in cosmetic durability and ensuring the stability of the cosmetic.

[0006]

Means for Solving the Problems In view of the above circumstances, the present inventors have conducted intensive studies and as a result, have found that specific inulin and / or
Also, by using a combination of a hydrolyzed inulin sugar fatty acid ester and an acrylic-silicone-based graft polymer, it has been found that, even in a cosmetic using a volatile cyclic silicone, it is possible to achieve both an improvement in cosmetic durability and an assurance of stability. Completed the invention.

That is, the present invention provides the following components (A) to
(C); (A) Fatty acid esterification degree per monosaccharide unit is 2.2.
The above-mentioned inulin and / or hydrolyzed inulin sugar fatty acid ester, and in the acyl group of the ester, 60 mol% or more of the total acyl group is selected from hexadecanoyl group, octadecanoyl group, eicosanoyl group, and docosanoyl group. One or two or more inulin and / or hydrolyzed inulin sugar fatty acid esters (B) an acrylic-silicone graft copolymer obtained by copolymerizing the following components (a) and (b): Component (a) : Organopolysiloxane compound having a radical polymerizable group in the molecule Component (b): a radical polymerizable monomer other than (a) (C) volatile cosmetic silicone; Furthermore, the component (A) is preferably an acyl group of an inulin and / or a hydrolyzed inulin sugar fatty acid ester having a degree of fatty acid esterification of 2.2 or more per monosaccharide unit.
The mole% or more is one or a combination of two or more selected from a hexadecanoyl group, an octadecanoyl group, an eicosanoyl group, and a docosanoyl group, and an acyl group having a branched hydrocarbon skeleton in 40 mole% of the remaining acyl groups. It is an inulin and / or a hydrolyzed inulin sugar fatty acid ester containing a group. Moreover,
Component (C) is a cosmetic, characterized in that it is octamethylcyclotetrasiloxane and / or decamethylcyclopentasiloxane. Hereinafter, the present invention will be described in detail.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION The degree of fatty acid esterification per monosaccharide unit of the component (A) used in the cosmetic of the present invention is 2.
Two or more inulin and / or hydrolyzed inulin fatty acid esters function as a volatile cyclic silicone gel structure imparting agent. Inulin and / or hydrolyzed inulin used for component (A) is a kind of polysaccharide,
-An oligosaccharide having fructose as a main constituent sugar and a hydrolyzate thereof. Inulin has a structure consisting of a chain of β-1,2 linked furanoid fructose units and having α-D-glucose linked at the reducing end by sucrose. Inulin is obtained from plants of the family Asteraceae, such as chicory and dahlias. The inulin and hydrolyzed inulin used in the present invention have two furanoid fructose units.
の も の 60 can be used. The fatty acid used for the component (A) is preferably a linear fatty acid having 16, 18, 20, or 22 carbon atoms. In component (A), the degree of substitution of fatty acid per fructose unit of inulin and / or hydrolyzed inulin is preferably 2.2 or more. When the degree of substitution is lower than 2.2, the solubility and the gel structure of the volatile cyclic silicone are not sufficiently imparted, and it is difficult to secure the stability, which is the object of the present invention.

Component (A) used in the cosmetic of the present invention
In the case of inulin and / or hydrolyzed inulin fatty acid ester having a degree of fatty acid esterification of 2.2 or more per monosaccharide unit, in the acyl groups of the ester, 60 mol% or more of the total acyl groups is hexadecanoyl. Group, an octadecanoyl group, an eicosanoyl group, and a docosanoyl group.
If the total amount of these acyl groups is less than 60 mol%, it is difficult to ensure the stability of the cosmetic. Regarding the carbon chain length of the acyl group, an acyl group having a smaller number of carbon atoms than the hexadecanoyl group does not provide sufficient gel structure, whereas an acyl group having a larger number of carbon atoms than the docosanoyl group gives a heavy feel during use. Accompanying or precipitation of the gelling agent occurs over time.

[0010] In the component (A) used in the cosmetic of the present invention, at least 60 mol% of the total acyl groups are one or two or more selected from hexadecanoyl, octadecanoyl, eicosanoyl and docosanoyl groups. If the degree of fatty acid esterification per monosaccharide unit is 2.2 or more, it may be substituted with another acyl group. Examples of other acyl groups include acetyl, propionyl, butyryl, isobutyryl, valeryl, isovaleryl, pivaloyl, hexanoyl, octanoyl, decanoyl, dodecanoyl, tetradecanoyl, and tetracosanoyl. A hexacosanoyl group, an octacosanoyl group, a triacontanoyl group, an oleoyl group, a benzoyl group, and a naphthoyl group.

[0011] The fatty acid ester of inulin and / or hydrolyzed inulin having a degree of acyl group substitution of 2.2 or more of the component (A) used in the present invention is obtained by mixing the inulin and / or hydrolyzed inulin with the fatty acid or fatty acid derivative. It is produced by reacting. Examples of the fatty acid derivative include an acid halide and an acid anhydride. The reaction between inulin and hydrolyzed inulin and a fatty acid or a fatty acid derivative can be easily performed by a conventionally known method. For example,
Inulin and hydrolyzed inulin can be obtained by dispersing inulin in dimethylformamide and pyridine, adding a fatty acid halide or a fatty acid anhydride thereto, and reacting at about 60 ° C. for about 2 hours.

In the component (A) used in the present invention, when it is desired to secure the stability and the fluidity of the cosmetic at the same time, the acyl group of the ester contains an acyl group having a branched hydrocarbon skeleton. It is desirable to do. The acyl group having a branched hydrocarbon skeleton preferably has 22 or less carbon atoms, and more preferably 18 or less carbon atoms. Examples of an acyl group having a branched hydrocarbon skeleton suitably used include an isostearoyl group, an isohexadecanoyl group, an isodecanoyl group, and an isooctanoyl group. Even in the case of the component (A) substituted with an acyl group having a branched hydrocarbon skeleton, at least 60 mol% of the total acyl groups are acyl groups having 16 to 22 carbon atoms, and the degree of acyl group substitution per unit sugar. Needs to be 2.2 or more.

The purpose of blending the component (A) in the present invention is as follows.
This is to ensure the stability of the cosmetic. The blending amount of the component (A) in the cosmetic of the present invention is not limited by the type of the cosmetic, the type of use, and the like, but is preferably 5 to 25 times the total oil amount.

The radically polymerizable monomer other than (a) in (b) means a compound having one radically polymerizable unsaturated bond in a molecule, such as methyl (meth) acrylate,
Ethyl (meth) acrylate, propyl (meth) acrylate, isopropyl (meth) acrylate, butyl (meth) acrylate, isobutyl (meth) acrylate, t-butyl (meth) acrylate, 2-ethylhexyl (meth) acrylate, cyclohexyl (meth) Alkyl (meth) acrylates such as acrylates, hydroxyalkyl (meth) acrylates such as 2-hydroxyethyl (meth) acrylate and 2-hydroxypropyl (meth) acrylate; Examples thereof include halogen-substituted alkyl (meth) acrylates all substituted with halogen atoms.

I can not get the fee. Conversely, if the ratio is 2/1 or more, and the proportion of the organopolysiloxane compound having a radical polymerizable group in the molecule is too large, the film-forming ability of the component (B) itself decreases, and the makeup also has a long lasting makeup. I can not get the fee.
