Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a nail polish having excellent stability, gloss of a coating film, and good cosmetic durability.

[0002]

2. Description of the Related Art Conventionally, a gelling agent has been added to a nail preparation in order to stably disperse organic and inorganic powders.
However, when a large amount of the gelling agent is used in order to stably maintain the system with only the gelling agent, there is a disadvantage that the organoleptic properties such as spreadability and smoothness and the usability are significantly reduced. In order to reduce the amount of the gelling agent, attempts have been made to improve the dispersibility and sedimentation of the powder by treating the powder with a surfactant and a silicone compound, thereby stabilizing the system. However, when a powder treated with a surfactant is used, since the nail polish contains a large amount of solvent components, the surfactant is eluted into the solvent, and the action of the eluted surfactant deteriorates cosmetic durability. There was a disadvantage. When powder treated with a silicone compound was used, the ability of the powder to prevent sedimentation was not sufficient.

[0003]

Therefore, by using a powder whose surface has been treated with a compound having a fluoroalkyl group, it is possible to obtain a beautiful nail preparation having good stability such as dispersibility and sedimentation of the powder and good cosmetic durability. However, depending on the resin solution, some of the resin solutions had poor affinity with the surface-treated powder, and as a result, the gloss of the coating film was not always satisfactory. Therefore, there has been a demand for a beautiful nail material which is excellent in stability such as dispersibility and sedimentation property and has good gloss and long lasting of the coating film.

[0004]

Under such circumstances, the present inventors have conducted intensive studies and as a result, by including a compound-treated powder having a specific perfluoropolyether group, the treated powder and the resin solution were mixed. As a result, the cosmetic effect can be obtained with a small amount of powder, and the gloss of the coating film becomes more favorable. It has been found that even if it is blended, there is little effect on usability such as ease of application and the like, and it is possible to obtain a beautiful nail preparation having excellent stability and good cosmetic durability, and completed the present invention. That is, the present invention relates to a perfluoropolyether dialkyl phosphoric acid and a salt thereof, a perfluoro polyether dialkyl sulfate and a salt thereof, a perfluoro polyether dialkyl carboxylic acid and a salt thereof, and a perfluoropolyether having a molecular weight of 300 or more. An object of the present invention is to provide a beauty nail preparation containing a powder treated with a compound having an ether group.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The treated powder used in the present invention is:

These compounds contain a perfluoropolyether group and have two polar groups selected from a phosphate group, a sulfate group and a carboxyl group to have an affinity for the powder surface. Having two of these polar groups improves the affinity. Further, a perfluoropolyether group refers to a group having at least two or more ether oxygens bonded to perfluoroalkylene or perfluoroalkyl. Accordingly, the perfluoropolyether alkyl phosphoric acid and salts thereof according to the present invention include perfluorooxy compounds having only one ether oxygen as described in JP-A-5-39209 and JP-A-5-58841. Compounds containing an alkyl group are not included. The molecular weight of the perfluoropolyether group is 300 or more, preferably 500 or more, and a preferable upper limit is about 7,000. If it is less than 300, water / oil repellency cannot be sufficiently imparted.

Preferred examples of the perfluorooxyalkylene group constituting the perfluoropolyether moiety include a perfluorooxymethylene group, a perfluorooxyethylene group, a perfluorooxyisopropylene group and a perfluorooxy n-propylene group.

In the case where the perfluoropolyether group contains two or more kinds of perfluorooxyalkylene groups, it is not limited to the case where the same kind is continuously polymerized, but may be random polymerization or block polymerization.

Further, from the viewpoint of the adhesion between the compound having a perfluoropolyether group according to the present invention and the substrate powder, it is necessary that the polar group having an affinity for the powder is not easily detached from the compound. It is necessary, and therefore, the compound preferably contains at least one or more oxyalkylene groups. More preferably, it is 1-2. This is because the presence of three or more oxyalkylene groups results in poor water / oil repellency of the compound. Similarly, an alkylene group may be contained in addition to the oxyalkylene group in terms of the fixing force. The preferred carbon number of the alkylene group is 2
It is as follows.

Examples of the compound having a perfluoropolyether group include perfluoropolyether dialkyl phosphoric acid and salts thereof, perfluoropolyether dialkyl sulfate and salts thereof, and perfluoropolyether dialkyl carboxylic acid and salts thereof. Among them, preferred are perfluoropolyether dialkyl phosphoric acids or salts thereof, and more preferred are compounds represented by the following formulas (3) and (4).
