Technical Field

The present invention relates to a cosmetic.

Background

Conventional makeup cosmetics have a problem of secondary adhesion caused by transfer of lipstick to a cup or the like after the lipstick is applied to the lips, for example. In addition, the foundation also has a problem that the applied cosmetic adheres to clothes and the like to cause secondary adhesion, which is called makeup removal along with a phenomenon that the cosmetic is mottled due to perspiration, grease, and the like.

Therefore, as makeup cosmetics which are less likely to cause secondary adhesion, that is, which are excellent in transfer resistance and less likely to cause makeup removal, there have been proposed cosmetics blended with various combinations of volatile and/or nonvolatile silicone oils and hydrocarbon oils.

For example, patent document 1 discloses a makeup cosmetic containing a silicone resin having a specific structure, a volatile silicone oil, and a powder, which is excellent in makeup removal prevention effect, has good extensibility, and can provide a refreshing feeling in use. However, the film formed of the silicone resin is hard, and sometimes feels a tight or stiff feeling, resulting in a dry feeling.

Further, patent document 2 discloses a cosmetic containing a methylphenylpolysiloxane, which has glossiness, good cosmetic durability and little possibility of cosmetic blurring by allowing the methylphenylpolysiloxane to be present on the surface. However, since the methylphenylpolysiloxane is a liquid, it is transferred by several times of eating and drinking, and the color is transferred.

Further, studies on the use of a silicone-grafted acrylic polymer as a film-forming agent have been made in patent documents 3, 4, and 5. Such a silicone-grafted acrylic polymer has a weak film and thus has a problem in secondary adhesion.

Further, patent document 6 describes a silicone-grafted acrylic polymer having a monomer unit derived from a long-chain alkyl monomer and a hydrophilic monomer, and although improvements in touch, compatibility, and smoothness are mentioned, these points are still insufficient.

Therefore, there is a need for a makeup cosmetic containing a film-forming agent, which is less likely to cause secondary adhesion, has good film flexibility and conformability, is excellent in use feeling, and imparts high gloss to a cosmetic film to improve a makeup effect.

Detailed Description

The present invention will be described in more detail below.

As described above, there has been a demand for a novel cosmetic having gloss, which is free from the tight feeling or stiff feeling of the conventional silicone resin film, has excellent feeling in use, conformability, and flexibility, and has a good effect of preventing color migration.

The present inventors have conducted extensive studies to achieve the above object and, as a result, have found that a cosmetic composition containing an acrylic silicone copolymer containing a monomer unit derived from a silicone macromonomer containing a phenyl group and a monovalent alkyl group having 1 to 6 carbon atoms in a specific ratio has glossiness, is free from a tight feeling or a stiff feeling, is excellent in a feeling in use, a conformability, and a softness, and has a good effect of preventing color transfer. In particular, it has been found that, in order to further enhance the above effects, the acrylic silicone copolymer preferably contains a monomer unit derived from an alicyclic (meth) acrylic monomer, and the present invention has been completed. There has been no prior case of actually synthesizing such an acrylic silicone copolymer and adding it to cosmetics.

That is, the present invention is a cosmetic characterized by having a structure containing at least a silicone macromonomer represented by the following general formula (1) as a monomer unit, and containing an acrylic silicone copolymer having a (meth) acrylic chain in the main chain (wherein the refractive index of the acrylic silicone copolymer is 1.47 or more).

The present invention will be described in more detail below, but the present invention is not limited thereto.

An organosilicon macromonomer represented by the general formula (1)

[ chemical formula 3]

In the formula (1), X is a divalent aromatic group having 6 to 12 carbon atoms or-COOR 4-, wherein R4 is a divalent aliphatic group which may contain an oxygen atom bonded to Si, R1 is a hydrogen atom or a methyl group, R2 is the same or different unsubstituted monovalent alkyl group having 1 to 6 carbon atoms, R3 is a phenyl group, n is 1 to 100, m is an integer of 1 to 100, and the composition ratio n/m is 1/2 to 4/1.

R1 in the silicone macromonomer represented by formula (1) is a hydrogen atom or a methyl group, preferably a methyl group.

R2 are each independently an unsubstituted monovalent alkyl group having 1 to 6 carbon atoms, preferably a methyl group, an ethyl group, a propyl group, a butyl group, a pentyl group, or a hexyl group, and more preferably a methyl group.

R3 is a phenyl group, and the silicone macromonomer represented by the above formula (1) contains a phenyl group in order to exhibit gloss of the resin.

X is a divalent aromatic group having 6 to 12 carbon atoms or-COOR 4-, preferably a divalent aromatic group having 6 to 8 carbon atoms or-COOR 4-. Examples of the divalent aromatic group include phenylene, tolylene, xylylene, mesitylene, and the like, and phenylene is preferable. In addition, -COOR4-, R4 is a divalent aliphatic group which may contain an oxygen atom bonded to Si, and a carbonyl group is bonded to a carbon atom of the main chain of the copolymer. R4 is, for example, - (CH2) a-, where a is an integer of 1 to 9, preferably an integer of 2 to 7, and more preferably an integer of 3 to 5.

n is 1 to 100, preferably 1 to 80, m is 1 to 100, preferably m is 1 to 80, and the composition ratio n/m is 1/2 to 4/1, preferably 1/2 to 3/1. It is difficult to prepare silicone macromers having n/m less than 1/2. When n/m is more than 4/1, the refractive index decreases, and when incorporated into a cosmetic, gloss cannot be sufficiently imparted, and the cosmetic effect decreases. In addition, the flexibility and touch of the film are reduced, and the secondary adhesiveness is also reduced.

Acrylic silicone copolymer

The refractive index of the acrylic silicone copolymer is 1.47 or more, preferably 1.48 or more and 1.54 or less. When the refractive index is less than 1.47, sufficient gloss cannot be imparted to the cosmetic, and the cosmetic effect is reduced.

The acrylic silicone copolymer preferably contains an alicyclic (meth) acrylic monomer as a monomer unit. Examples of the alicyclic (meth) acrylic monomer include adamantyl (meth) acrylate, isobornyl (meth) acrylate, dicyclopentenyl (meth) acrylate, dicyclopentenyloxyethyl (meth) acrylate, and dicyclopentanyl (meth) acrylate, and adamantyl (meth) acrylate, isobornyl (meth) acrylate, dicyclopentenyl (meth) acrylate, and dicyclopentanyl (meth) acrylate are preferable, and adamantyl (meth) acrylate and dicyclopentanyl (meth) acrylate are more preferable. The alicyclic (meth) acrylic monomer has a high refractive index and can impart high gloss. Further, since the acrylic silicone macromonomer of formula (1) has a high phenyl group content, the solubility in a volatile silicone oil or a volatile organic oil tends to be low, and therefore, the solubility can be improved by containing a hydrocarbon moiety derived from a monomer unit of an alicyclic (meth) acrylic monomer. In addition, adamantyl (meth) acrylate and dicyclopentanyl (meth) acrylate have relatively high glass transition temperatures, and can form a strong film, and therefore, the secondary adhesion can be improved.

Preferably, the acrylic silicone copolymer contains 30 to 70 mass% of a silicone macromonomer represented by the general formula (1) as a monomer unit and 30 to 70 mass% of an alicyclic (meth) acrylic monomer as a monomer unit. The silicone macromonomer represented by the general formula (1) is preferably 40 to 60 mass%, and the alicyclic (meth) acrylic monomer is preferably 30 to 60 mass%.

The polymerization for preparing the acrylic silicone copolymer of the present invention can be carried out in the presence of the above-mentioned monomers and radical polymerization initiators such as benzoyl peroxide, lauroyl peroxide, azobisisobutyronitrile, and the like. The polymerization method may be any of solution polymerization, emulsion polymerization, suspension polymerization, and bulk polymerization. Among these, the solution polymerization method is a preferred method because the dispersion of the Gel Permeation Chromatography (GPC) spectrum and the weight average molecular weight of the copolymer can be easily adjusted as appropriate when the obtained weight average molecular weight is checked. Examples of the solvent used in the polymerization include aliphatic organic solvents such as pentane, hexane, decane, dodecane, hexadecane and octadecane, and aromatic organic solvents such as benzene, toluene and xylene. The polymerization reaction may be carried out in an organic solvent such as an alcohol organic solvent such as methanol, ethanol, propanol, butanol, hexanol, decanol, a halogenated organic solvent such as chloroform or carbon tetrachloride, or a ketone organic solvent such as acetone or methyl ethyl ketone.

The acrylic silicone copolymer produced in this way preferably has a weight average molecular weight in terms of polystyrene calculated by GPC of 700 to 500,000, particularly preferably 5000 to 400,000, and further preferably 8000 to 200,000.

Further, it is preferable that the acrylic silicone copolymer of the present invention is not precipitated or separated at 25 ℃ when it is mixed with a volatile silicone oil or a volatile organic oil at a mass ratio of 7: 3. Such a condition can be satisfied if the composition of the acrylic silicone copolymer is as described above.
