Description

The present invention relates to a powder surface treatment agent, and more particularly to a powder surface treatment agent having a polycycloolefin skeleton and remarkably improving the dispersibility of the powder. Cosmetics using the powder are excellent in adhesion to skin, hair, etc., and give a finish excellent in water resistance and sebum resistance.

Various powder components are blended in cosmetics by appropriately combining oily or aqueous components. In order to improve the dispersibility of the powder in an oily or aqueous component and improve the feel of the cosmetic, surface treatment is usually applied to the powder.

Examples of surface treatment agents include metal soaps obtained by metathesis of carboxylic acids and polyvalent metals (Patent Document 1), compounds having N-acylated basic amino groups (Patent Documents 2 and 3), methyl hydrogen polysiloxane. (Patent Documents 4 and 5), perfluoroalkylsilane (Patent Document 6), silane coupling agent (Patent Document 7), one-end alkoxy-modified silicone (Patent Document 8), acidic ester oil (Patent Document 9), etc. Things are known.

Cosmetics containing metal soap-treated powder tend to have poor extensibility. A powder treated with a compound having an N-acylated basic amino group is inferior in water repellency. Powders treated with chilled hydrogen polysiloxane, silane coupling agent, and alkoxy-modified silicone organosiloxane are not sufficiently dispersible in oily components other than silicone oils, have poor compatibility with sebum, and adherence Inferior to The powder treated with perfluoroalkylsilane has high water and oil repellency, and poor adhesion to the skin and dispersibility in each medium.

On the other hand, a polycycloolefin copolymer is known (Patent Document 10). The copolymer is excellent in film forming ability and is used for gas permeable membranes, contact lenses and the like.

The amount of the catalyst used can be polymerized at a concentration of 1 to 1000 ppm, preferably 5 to 500 ppm, relative to the raw material monomer. If it is less than 5 ppm, the polymerization rate is slow and the practicality is poor, and if it exceeds 500 ppm, it may be economically undesirable.

  Hydrogenation of the obtained copolymer is performed, for example, by converting the main chain carbon-carbon double bond of the silicone-modified polycycloolefin to a saturated single bond using hydrogen gas in the presence of a hydrogenation catalyst. be able to.

Among these, noble metal complex catalysts such as rhodium and ruthenium, palladium-carbon, etc. from the point that the main chain carbon-carbon double bond of the polymer can be selectively hydrogenated without causing side reactions such as functional groups. It is preferable to use a palladium-supported catalyst, particularly a ruthenium carbene complex catalyst.

The ruthenium carbene complex catalyst can be used as both a ring-opening metathesis reaction catalyst and a hydrogenation catalyst. In this case, the ring-opening metathesis reaction and the hydrogenation reaction can be performed continuously. When the ring-opening metathesis reaction and the hydrogenation reaction are continuously performed using the ruthenium carbene complex catalyst, a catalyst modifier such as ethyl vinyl ether or a vinyl compound or α-olefin is added to activate the catalyst. Therefore, a method of starting the hydrogenation reaction is also preferably employed.

The hydrogenation reaction is preferably performed in an organic solvent. As an organic solvent, it can select conveniently by the solubility of the hydride to produce | generate, The organic solvent similar to the above-mentioned polymerization solvent can be used. Therefore, the reaction can be carried out without changing the solvent after the polymerization reaction, either directly from the reaction solution or from the reaction solution or by adding a hydrogenation catalyst.

The conditions for the hydrogenation reaction may be appropriately selected according to the type of hydrogenation catalyst used. The usage-amount of a hydrogenation catalyst is 0.01-50 weight part normally with respect to 100 weight part of ring-opening polymers, Preferably it is 0.05-10 weight part. When the reaction temperature is 100 ° C. to 200 ° C. or higher, side reactions tend to occur. The reaction pressure of hydrogen is usually 0.01 to 10.0 MPa, preferably 0.1 to 5.0 MPa. When the hydrogen pressure is 0.01 MPa or less, the hydrogenation reaction rate decreases. If it is 5.0 MPa or more, a high voltage device is required.

  By the hydrogenation reaction performed as described above, 50% or more, preferably 80% or more, and most preferably 90% or more of the main chain carbon-carbon double bonds can be hydrogenated.
