Description
CROSS-REFERENCE TO RELATED APPLICATION

This non-provisional application claims priority under 35 U.S.C. §119(a) on Patent Application No. 2010-130784 filed in Japan on Jun. 8, 2010, the entire contents of which are hereby incorporated by reference.


TECHNICAL FIELD

The present invention relates to a cosmetic product and, more particularly, to the one containing a film-forming polymer composed of building blocks with cycloolefin skeletons. Said polymer has good compatibility with a variety of oils, especially silicone oil, readily spreads on the skin and hair without sticky feeling, and prevents the cosmetic product from staining clothes.


BACKGROUND ART

Cosmetic products are usually incorporated with a film-forming polymer so that they keep long. There is much need for development of make-up cosmetic products and sun care cosmetic product superior in water resistance and perspiration resistance. This need has been met by incorporation with trimethylsiloxy silicic acid or silicone-modified acrylic resin. However, when added sufficiently, the former gives a squeaking feel after application on account of a hard film it produces. It also produces a brittle film which easily peels off when pressed or stretched. Moreover, cosmetic products containing it easily stick to clothes when scratched by clothes after application. (This phenomenon will be referred to as “secondary sticking” hereinafter.) By contrast, said silicone-modified acrylic resin gives a soft good feel but has a bit of problem in secondary sticking due to its weak film.


Another known additive is a polycycloolefin polymer (as disclosed in JP-A 2007-291150). This polymer is superior in film-forming performance and finds use as gas-permeable film and contact lenses.


For more information, refer to JP-A 2010-24154.


SUMMARY OF INVENTION

The present inventors found that the foregoing problems with film-forming polymers in related art are solved by using a polycycloolefin polymer whose skeleton has specific functional groups. This finding led to the present invention.


The present invention, therefore, provides the following cosmetic product containing Film-Forming Polymer:

The addition polymerization for the compounds represented by the formulas (6), (7), and (10) may be accomplished in the usual way under normal pressure at 20 to 80° C. in the presence of a polymerization catalyst and cocatalyst with stirring in an inert gas atmosphere, with said compounds (as monomers) dissolved in an aromatic hydrocarbon solvent such as toluene and xylene. The polymerization catalyst may be any of metal complexes containing an element selected from the 8th, 9th, and 10th groups of the periodic table. Such elements include iron (Fe), cobalt (Co), nickel (Ni), ruthenium (Ru), rhodium (Rh), palladium (Pd), and platinum (Pt). Preferred metal complexes include metallocene compounds and β-diketone compounds of nickel (Ni) or palladium (Pd). The cocatalyst includes organoaluminum compounds and ionic boron compounds. Preferred organoaluminum compounds include methylaluminoxane and preferred ionic boron compounds include triphenylcarbenium tetrakis(pentafluorophenyl) borate.


The amount of the catalyst and cocatalyst mentioned above should preferably be 0.001 to 100 mmol atom for 1 mol of the total amount of the monomers represented by the formulas (1), (2), and (3).


The polymerization system may be incorporated with a molecular weight modifier according to need. The molecular weight modifier includes, for example, hydrogen, α-olefins (such as ethylene, butene, hexene, and octene), aromatic vinyl compounds such as styrene, 3-methylstyrene, and divinyl benzene, unsaturated ethers such as ethyl vinyl ether, and vinyl silicon compounds such as tris(trimethylmethoxy)vinylsilane, divinyldihydrosilane, and vinylcyclotetrasiloxane.


The ratio of solvent to monomer, the polymerization temperature, the polymerization time, and the amount of the molecular weight modifier widely vary depending on the catalyst employed and the structure of the monomers. Hence, they cannot be established unconditionally. They should be properly specified according to the structure of the intended polymer. The molecular weight of the polymer may be adjusted by the amount of the polymerization catalyst, the amount of the molecular weight modifier, the ratio of conversion from monomer to polymer, and the polymerization temperature.


The polymerization is suspended by adding any compound selected from water, alcohol, ketone, and organic acid. The polymerization solution may be given a mixture of alcohol and aqueous solution of acid such as lactic acid, malic acid, and oxalic acid to separate and remove catalyst residues from it. It is also possible to remove catalyst residues by adsorption with activated carbon, diatomaceous earth, alumina, or silica, or by filtration.


The resulting polymer coagulates as the polymerization solution is put in an alcohol such as methanol and ethanol or ketone such as acetone and methyl ethyl ketone. The resulting coagulation is separated by drying under reduced pressure at 60 to 150° C. for 6 to 48 hours. This step also removes catalyst residues and unreacted monomers from the polymerization solution. Unreacted monomers containing the above-mentioned siloxane can be easily removed by using a solvent composed of alcohol or ketone and cyclic polysiloxane such as octamethylcyclotetrasiloxane and decamethylcyclopentasiloxane.

Production (1) of Polymer (I-1)
Synthesis of tris(trimethylsiloxy)silylnorbornene-co-norbornene addition copolymer

A glass container with its atmosphere replaced by nitrogen was charged with 140 mL of toluene. In this toluene were dissolved 44.8 g (0.115 mol) of monomer-A, 5.8 g (0.062 mol) of monomer-C (norbornene), and 37 mg (40 μmol) of trityltetra(pentafluorophenyl)borate [Ph3C][B(C6F5)4].


To the container were further added a catalyst solution prepared separately including 9 mg (40 μmol) of cyclopentadienyl(aryl)palladium [C5H5PdC3H5] and 12 mg (40 μmol) of tricyclohexylphosphine (PCy3), which are dissolved in 15 mL of toluene. Polymerization reaction was carried out at room temperature (25° C.) for five hours.


After the completion of reaction, the reaction product was poured into a large amount of methanol so that the polymer separated out. After filtration and washing, the separated solids were dried under reduced pressure at 60° C. for five hours. Thus there was obtained the desired polymer (I-1) in an amount of 31.8 g (yields: 63%).


The thus obtained polymer was found to have a molecular weight (Mn) of 601,000 (measured by GPC) and a molecular weight distribution (Mw/Mn) of 1.49. Analysis by 1H-NMR spectrum indicated that the polymer is composed of monomer-A and monomer-C in a ratio of A/C=67/33 (mol/mol).


Production (2) of Polymer (I-2)
Synthesis of tris(trimethylsiloxy)silylnorbornene-co-norbornene addition copolymer (with a low molecular weight)

A glass container with its atmosphere replaced by nitrogen was charged with 400 mL of toluene. In this toluene were dissolved 202.4 g (0.52 mol) of monomer-A, 26.4 g (0.28 mol) of monomer-C (norbornene), and 1.1 g (0.01 mol) of 1-octene.


To the container were further added a catalyst solution prepared separately containing 6 mg (20 μmmol) of bis(acetylacetonate)palladium [Pd(C5H7O2)2], 3 mg (10 μmol) of tricyclohexylphosphine (PCy3), and 22 mg (24 μmol) of trityltetra(pentafluorophenyl)borate {[Ph3C][B(C6F5)4]}, which are dissolved in 15 mL of toluene. Polymerization reaction was carried out at 60° C. for ten hours.


After the completion of reaction, the reaction product was poured into a large amount of methanol so that the polymer separated out. After filtration and washing, the separated solids were dried under reduced pressure at 120° C. for eight hours. Thus there was obtained the desired polymer (I-2) in an amount of 160.2 g (yields: 70%).


The thus obtained polymer was found to have a molecular weight (Mn) of 230,000 (measured by GPC) and a molecular weight distribution (Mw/Mn) of 2.56. Analysis by 1H-NMR spectrum indicated that the polymer is composed of monomer-A and monomer-C in a ratio of A/C=67/33 (mol/mol).


Production (3) of Polymer (II)
Synthesis of bis(trimethylsiloxy)methylsilylnorbornene-co-norbornene addition copolymer

The same procedure as in Production (1) of polymer was repeated except that monomer-A was replaced by 36.2 g (0.115 mol) of monomer-B. There was obtained the polymer (II) in an amount of 29.4 g (yields: 70%). This polymer was found to have a molecular weight (Mn) of 724,000 and a molecular weight distribution (Mw/Mn) of 1.38 and was also found to be composed of monomer-B and monomer-C in a ratio of 68/32 (mol/mol).


Production (4) of Polymer (III)
Synthesis of bis(trimethylsiloxy)methylsilylnorbornene polymer

The same procedure as in Production (2) of polymer was repeated except that monomer-B alone was used in an amount of 55.7 g (0.177 mol). There was obtained the polymer (III) in an amount of 30.6 g (yields: 55%). This polymer was found to have a molecular weight (Mn) of 632,000 and a molecular weight distribution (Mw/Mn) of 1.39.


Solution of Polymer (I-1) in Methyltrimethicone (M3T)

Polymer (I-1) and M3T were placed in a separable flask, with its atmosphere replaced by nitrogen. After dissolution at 80° C. by a glass stirrer, there was obtained a 30 wt % homogeneous solution.


Solution of Polymer (I-1) in Isododecane

The same procedure as above was repeated to give a 30% solution except that the solvent was replaced by isododecane. The resulting solution was found to have a viscosity of 700 Pas at 25° C.


For the purpose of comparison, polymer (I-1) and isododecane were mixed in a separable flask with its atmosphere replaced by nitrogen at 80° C. by a glass stirrer to give a 30 wt % solution. However, the resulting product was found to lack fluidity at 25° C. The procedure was modified to give a 20 wt % solution and a 10 wt % solution. However, these solutions were found to have a viscosity of 1,500 Pa·s and 6.5 Pa·s, respectively.


Solution of Polymer (I-2) in Dimethicone


Polymer (I-2) and dimethicone (KF-96L-2 cs, made by Shin-Etsu Chemical Co., Ltd.) were placed in a separable flask, with its atmosphere replaced by nitrogen. After dissolution at 80° C. by a glass stirrer, there was obtained a 30 wt % homogeneous solution.


Solution of Polymer (I-2) in Decamethylcyclopentasiloxane (D5)

Polymer (I-2) and D5 were placed in a separable flask, with its atmosphere replaced by nitrogen. After dissolution at 80° C. by a glass stirrer, there was obtained a 10 wt % homogeneous solution.


Solution of Polymer (II) in M3T

Polymer (II) and M3T were placed in a separable flask, with its atmosphere replaced by nitrogen. After dissolution at 80° C. by a glass stirrer, there was obtained a 10 wt % homogeneous solution.


Solution of Polymer (III) in D5

Polymer (III) and D5 were placed in a separable flask, with its atmosphere replaced by nitrogen. After dissolution at 80° C. by a glass stirrer, there was obtained a 10% homogeneous solution.


Those polymers obtained as mentioned above are soluble in volatile solvents, such as isododecane, D5, dimethicone (2 cs), and M3T, which are used for cosmetic products. The resulting solutions vary in viscosity depending on the composition and molecular weight of the polymer. Consequently, the polymers of the present invention can be used as a thickener for cosmetic products. For example, the solution in D5 has a much higher viscosity than the solution in isododecane. Thus, the solution in D5 can be used to increase the viscosity of the solution of polymer (I-1) or (I-2) in isododecane.


As mentioned above, when dissolved in a volatile solvent, the polymer of the present invention gives a solution that forms a flexible tough film. Therefore, the cosmetic product incorporated with the solution of the polymer, even in small quantities, will exhibit improved rubbing resistance and transfer resistance. Moreover, the polymer of the present invention greatly shrinks when it forms film. Thus, it is expected to find use as antiwrinkle preparations and hair and eyelash preparations. In addition, the polymer (I-1), which has a high molecular weight, easily forms strings and becomes sticky when dried; therefore, it will be used for an improved mascara that forms thicker and longer eyelashes.
