Description

This application claims the priority of Japanese Patent Application No. 2000-55846 filed on Mar. 1, 2000, Japanese Patent Application No. 2000-333784 filed on Oct. 31, 2000 and Japanese Patent Application No. 2000-333785 filed on Oct. 31, 2000 which are incorporated herein by references.

TECHNICAL FIELD

The present invention relates to a film composition which is solidified in water, a manicure using the same and a manicuring method. In particular, the present invention relates to an improvement of a solvent of a composition of which the film is rapidly solidified in water.

BACKGROUND ART

Film compositions used as a nail enamel, a nail enamel base coat, a nail enamel over coat or the like are composed of water insoluble film materials, such as nitrocellulose, which is dissolved in organic solvents, such as ethyl acetate, butyl acetate or acetone.

A manicure is also a film composition. Some properties are needed for a manicure in relation to a film appearance and a film forming process. For example, a proper color tone and a proper gloss of a film are needed. Further, properties such as

(1) a proper viscosity for applying a nail with ease

(2) a rapid drying speed of a film after it is applied on a nail and a formation of an uniform film surface on the nail, and

(3) a sufficient adhesion to the nail

are also needed. In these properties a rapid drying speed after applying on a nail and a formation of an uniform film surface are closely related to each other. Namely, if a drying speed of a manicure after applying on a nail is too rapid, a viscosity of the applied film may become too high or the applied film may be dried and hardened while the manicure is applied. As a result, forming an uniform film surface may be difficult. On the other hand, if a drying speed of a manicure after applied on a nail is too slow, a proper usability may not be obtained. To balance these two properties the drying time is normally adjusted to be 3 to 8 minutes.

However, more rapid drying time has been required.

A solvent in a manicure applied on a nail is normally removed by a volatilization in the air. But a method to remove a solvent from a manicure applied on a nail by a concentration gradation of the solvent has also been considered. For example, it was disclosed that after a manicure is applied on a nail the applied portion was dipped in water and a solvent in the film formed on the nail was released into water to obtain a rapid drying speed (Japanese Patent Laid Open Shou No. 47-43348).

However this manicure tends to form a whitened film, and it leaves a trace of blushing on a film. Thus it does not satisfy the properties needed for a manicure.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1

shows explanatory drawing of use of a film composition of the present invention and the mechanism of film formation, and

FIG. 2

shows explanatory drawing of a change according to time of a solvent composition in a film formed by applying the composition of the present invention on a nail measured by a gas chromatography when the film is dipped in water.

BEST MODE FOR CARRYING OUT THE INVENTION

Preferable embodiments of the invention will be explained in the following.

FIG. 1

illustrates use of a film composition of the present invention and mechanism of film solidification.

A film of the composition can be dried in the air, but when the film is dipped in water after applied on a nail (FIG.

1

(A)) more rapid film drying is realized (FIGS.

1

(B), (C)). This rapid drying by dipping in water is thought to be caused by the reason that when the film is dipped in water a solvent in the film dissolves into the water and minute amounts of water penetrates into the film. Thus the composition of solvent ingredients in the film would be changed and it promotes a precipitation of the film materials.

FIG. 2

illustrates a change according to time of a solvent composition in a film formed by applying the composition of the present invention on a nail measured by a gas chromatography when the film is dipped in water. It is obvious from

FIG. 2

that a solvent in the film dissolves into water rapidly and minute amounts of water is simultaneously penetrates into the film. If dipping time is required to be less than 2 minutes for utility it is required that film materials precipitate in a mixed solvent of water and the solvent ingredients of the composition within that time range. On the other hand, when film materials are precipitated in water, the film surface tends to be whitened by some solvent compositions. In this case manicuring effect may be lost. From these point of view applicants found the compounds (I), (II) and (III) are preferable as solvent ingredients of a film composition of the present invention.

In Table 7 butyl acetate, which is a generally used solvent for a manicure, was mixed with diethylene glycol diethyl ether of the compounds (I). From Table 7 it is recognized that sufficient durability was maintained when the amount of butyl acetate was less than 50 weight percent per solvent On the other hand, when the amount of butyl acetate exceeded 50 weight percent per solvent the durability became worse.

Next, combinations of the compounds (I) as a main solvent ingredient and other solvent ingredients consisting of the compounds (II) and (III) were investigated. The results are shown in Table 8.

It is recognized from Table 8 that when diethylene glycol diethylether, which is one of the compound (I), was mixed with acetone, which is one of the compound (II), or ethylene glycol monobutyl ether, which is one of the compounds (III), and the mixture was used as a solvent, the durability is more superior to the case where butyl acetate, which is generally used as a solvent of manicure, was mixed with diethylene glycol diethylether and used the mixture as a solvent.

Next, the case where acetone and methylethylketone were used as main solvent ingredients was examined. In this case the evaluation shown in the following was also conducted.

Fine Finish

A sample was applied on a nail of each women panels. The applied portion was dried by dipping the nail in water. An appearance of the solidified film on the nail was observed and evaluated according to the following standard.

⊚: The finish was fine and no trace of brush was observed. Fine finish was obtained for all of the cases.

◯: The finish was fine and traces of brush were little observed. Fine finish was obtained for most of the cases.

Δ: Traces of brush were observed for some cases.

×: Fine finish was not obtained for most of the cases.

The results are shown in Table 9 and Table 10.

From Table 9 it is recognized that when a compound which has b.p. (boiling point) of more than 100° was mixed with acetone as a solvent ingredient the good drying speed and uniform film surface with no whitening were obtained. Further, Application was easy and finish of the applied nail was fine.

On the other hand, when only acetone or a mixture of acetone and a relatively volatile compound (b.p. of less than 100° C.) was used as a solvent, application was difficult because of fast volatilization of acetone. And traces of brush remained on the film surface. Thus fine finish was not sufficiently obtained.

From Table 10 it is recognized that when a compound which has b.p. (boiling point) of more than 100° C. was mixed with methyl ethyl ketone as a solvent ingredient good drying speed and uniform film surface with no whitening were obtained. Further, application was easy and finish of the applied nail was fine.

On the other hand, when only methyl ethyl ketone or a mixture of methyl ethyl ketone and a relatively volatile compound (b.p. of less than 100° C.) was used as a solvent, application was difficult because of fast volatilization of methyl ethyl ketone. And traces of brush remained on the film surface. Thus fine finish was not sufficiently obtained.

Next, the relationships between combination amount of a compound which has b.p. of more than 100° C. in a solvent of a sample, and ease of application and fine finish were examined. The results are shown in Table 11 and Table 12.

It is recognized from the results in Table 11 that when the combination amount of a compound which has b.p. of more than 100° C. (4-methyl-2-pentanone: b.p. of 117 to 118° C.) in the solvent was more than 15 weight percent per solvent good drying speed and uniform film surface with no whitening were obtained. Further, application was easy and finish of the applied nail was fine.

On the other hand, when the combination amount of 4-methyl-2-pentanone was less than 15 weight percent per solvent, application was not necessarily easy and finish of the applied nail was not sufficiently fine.

It is recognized from the results in Table 12 that when the combination amount of a compound which has b.p. of more than 100° C. (2-hexanone: b.p. of 127° C.) in the solvent was more than 15 weight percent per solvent good drying speed and uniform film surface with no whitening were obtained. Further, application was easy and finish of the applied nail was fine.

On the other band, when the combination amount of 2-hexanone was less than 15 weight percent per solvent, application was not necessarily easy and finish of the applied nail was not sufficiently fine.

Further the film properties were examined for samples which use the compounds (II) and (III) with a boiling point of more than 100° C. as solvent ingredients. The results are shown in Table 13.

It is recognized from Table 13 that the samples which use the compounds (II), (III) with a boiling point of more than 100° C. showed good properties.

B. Preferable Compositions When Used as a Manicure

To obtain more preferable film properties for use as a manicure further investigation was done about a resin and a composition of a solvent of samples. In the following the new evaluation standards were used for the in detail evaluation of ease of application and an uniformity of a film surface to investigate more preferable compositions for use as a manicure. The new evaluation standards are as follows. The evaluation standards of the dying time in the following are the same as the above-described evaluation standards.

Ease of Application on a Nail

The new evaluation standard is as follows.

Each sample was filled in a 10 ml glass bottle equipped with an application brush. Then ease of application on a nail was evaluated based on the following evaluation standard.

The Symbol ⊚: Very Good (The feeling of application was smooth and it was easy to finely apply on a nail.)

The Symbol ◯: Good

The Symbol Δ: A little Bad (The application was a little difficult.)

The Symbol ×: Bad (The application was difficult.)

Uniformity of a Film Surface

A sample was applied on a nail with brushing the nail once and the film formed on the nail by applying the sample was dipped in water. Then a surface appearance of the solidified film was evaluated based on the following evaluation standard.

The Symbol ⊚: Very Good (The surface of the film was fine and smooth.)

The Symbol ◯: Good

The Symbol Δ: A little Bad (The surface appearance of the film was a little cloudy.)

The Symbol ×: Bad (The film surface was whitened.)

At first, sucrose ester resin was selected and samples containing sucrose resin were examined in the following.

Film properties of each samples with different solvent were examined. The results are shown in Table 14.

It is recognized from Table 14 that when a mixture of diethylene glycol diethyl ether, which is one of the compounds (I), and acetone, which is one of the compounds (II) was used as a solvent the drying speed in water was rapid and fine film surface with no whitening was obtained.

On the other band, when butyl acetate, which has been commonly used as a solvent of a manicure, was used as a solvent the film was not dried by dipping in water. When ethylene glycol monoethylether was used as well as the prior art, though film drying was performed, the film surface was whitened and an appearance of the film lacked uniformity.

Further film properties of samples containing a solvent consisting of the compounds (I) and the compounds (II) were examined. The results are shown in Table 15.

It is recognized from Table 15 that, when a mixture of the compounds (I) and the compounds (II) was used as a solvent, the drying speed in water was rapid and fine film surface was obtained.

Next, the samples which use resins of the following (1) to (5) as one of the film materials were evaluated. Further, adhesion to a nail, which is one of the important properties for manicure, was also evaluated according to the following procedure. The results are shown in Table 16.

Resin (1) Sucrose Acetate Isobutylate (Sucrose ester resin)

Resin (2) Sucrose benzoate (Sucrose ester resin)

Resin (3) Phthalic acid/Glycerin/Glycidyl Versatate (Alkyd resin)

Resin (4) Alkyl Acrylate/Alkyl Methacrylate Copolymer (Acrylic resin)

Resin (5) Methacrylic acid/Acrylic acid 12-Hydroxyethyl Methacrylate Copolymer (Acrylic resin)

The Adhesion Test

A sample was extended onto a glass board by an applicator, and a film of the sample with a constant thickness formed on the glass board was dried by dipping in water. Then the film was separated to 100 square sections. These sections were made according to the procedure in which the film was mechanically scratched by a sharpened needle to give 11 linear traces and the other 11 linear traces crossed at right angles to said 11 linear traces to form 100 separated square sections (1 mm×1 mm). Then the adhesion to a nail was evaluated according to the following evaluation standard in consideration of the ratio of the number of the remained square film sections on the glass board. Namely, A higher number of the remained square film sections on the glass board means better adhesion to a nail (Peeling off the film from a nail is relatively difficult). On the other hand, a lower number of the remained square film sections on the glass board means worse adhesion to a nail (Peeling off the film from a nail is relatively easy).

The evaluation Standard

The symbol ⊚: A ratio of a number of remained square films on the glass board was more than 80 percent.

The symbol ◯: A ratio of a number of remained square films on the glass board was more than 60 percent and smaller than 80 percent.

The symbol Δ: A ratio of a number of remained square films on the glass board was more than 40 percent and smaller than 60 percent.

The symbol ×: A ratio of a number of remained square films on the glass board was more than 40 percent.

It is recognized that from Table 16 that when sucrose ester resins (Resin(1), (2) in Table 16) were used as a film material good properties were obtained.

On the other hand, when alkyd resin or acrylic resin (Resin (3), (4), (5) in Table 16) were used as a film material, though the drying speed were rapid, the film surface was a little whitened and uniformity of the film appearance were a little inferior to that of the case where sucrose ester resins were used.

From the above results it is recognized that a combination of a specified resin (sucrose ester resin) and a specified solvent composition (the compounds (I) and the compounds (a)) is needed to obtain excellent film properties.

Next, the case where a solvent consisting of the compounds (I) and the compounds (II) was mixed with the other solvent ingredients was examined. The results are shown in Table 17, Table 18 and Table 19.

In Table 17 butyl acetate, which is a generally used solvent for a manicure, was mixed with a solvent consisting of diethylene glycol diethyl ether, which is one of the compounds (I) and acetone, which is one of the compounds (II). From Table 17 it is recognized that sufficient film properties were maintained when the amount of butyl acetate was less than 50 weight percent per solvent. On the other hand, when the amount of butyl acetate exceeded 50 weight percent per solvent the film properties became worse.

In Table 18 and Table 19 alkylene glycol monoethers such as ethylene glycol monoethyl ether or ethylene glycol monobutyl ether were mixed with a solvent consisting of diethylene glycol diethyl ether, which is one of the compounds (I) and acetone, which is one of the compounds (II). From Table 18 and Table 19 it is recognized that sufficient film properties were maintained even when the amount of alkylene glycol monoether was twice of the total amount of diethylene glycol diethyl ether and acetone, and that was different from the results of the above-described case where butyl acetate was used.

Next, a mixed solvent consisting of the compounds (I), (II) and (III) was mixed with a generally used solvent for a manicure, and film properties were examined. The results are shown in Table 20.

In Table 20 butyl acetate, which is a generally used solvent for a manicure, was mixed with a solvent consisting of diethylene glycol diethyl ether which is one of the compounds (I), acetone which is one of the compounds (II) and ethylene glycol monobutyl ether which is one of the compounds (III). From Table 20 it is recognized that sufficient film properties were maintained when the amount of butyl acetate was less than 50 weight percent per solvent. On the other band, when the amount of butyl acetate exceed 50 weight percent per solvent the film properties became worse.

Next, the combination amounts of the compounds (I) and the compounds (I) were varied and the relations between the combination amounts and the properties of the drying speed, ease of application and uniformity of the film surface were examined. The results are shown in Table 21.

It is recognized from Table 21 that when a combination amount of diethylene glycol diethyl ether, which is one of the compound (I), is 1 to 60 weight percent per the total amount of a sample and a combination amount acetone, which is one of the compound (II), is 1 to 60 weight percent per the total amount of a sample good properties were obtained.

On the other hand, when a combination amount of diethylene glycol diethyl ether and acetone is outside the above-mentioned range, deterioration of some properties were recognized.

Next, the combination amounts of the compounds (I) and the compounds (II) were varied and the relations between the combination amounts and the adhesion were examined. The results are shown in Table 22.

It is recognized from Table 22 that when a combination amount of diethylene glycol diethyl ether, which is one of the compounds (I), is 5 to 40 weight percent per the total amount of a sample and a combination amount acetone, which is one of the compounds (II), is 20 to 60 weight percent per the total amount of a sample the good adhesion was obtained.

On the other hand, when a combination amount of these ingredients was outside the above-mentioned range, the adhesion was inferior to the adhesion obtained by the above-mentioned condition.

In the following sulfonamide resin was selected and samples containing sulfonamide resin were examined.

Film properties of each samples with different solvent were examined. The results are shown in Table 23.

It is recognized from Table 23 that when a mixture of diethylene glycol diethyl ether, which is one of the compounds (I), and acetone, which is one of the compounds (II) was used as a solvent the drying speed in water was rapid and fine film surface with no whitening was obtained.

On the other hand, when butyl acetate, which has been commonly used as a solvent of a manicure, was used as a solvent the film was not dried by dipping in water. When ethylene glycol monoethylether was used as well as the prior art, though film drying was performed, the film surface was whitened and an appearance of the film lacked uniformity.

Further film properties of samples containing a solvent consisting of the compounds (I) and the compounds (II) were examined. The results are shown in Table 24.

It is recognized that from Table 25 that when sulfonamide resins (Resin (1), (2) in Table 25) were used as a film material good properties were obtained.

On the other hand, when alkyd resin or acrylic resin (Resin (3), (4), (5) in Table 25) were used, though the drying speed were rapid, the film surface was a little whitened and uniformity of the film appearance were a little inferior to that of the case where sulfonamide resins were used.

From the above results it is recognized that a combination of a specified resin (sulfonamide resin) and a specified solvent composition (the compounds (I) and the compounds (II)) is needed to obtain excellent film properties.

Next, the case where a solvent consisting of the compounds (I and the compounds (II) was mixed with the other solvent ingredients was examined. The results are shown in Table 26, Table 27 and Table 28.

In Table 26 butyl acetate, which is a generally used solvent for a manicure, was mixed with a solvent consisting of diethylene glycol diethyl ether, which is one of the compounds (I) and acetone, which is one of the compounds (II). From Table 26 it is recognized that sufficient film properties were maintained when the amount of butyl acetate was less than 50 weight percent per solvent. On the other hand, when the amount of butyl acetate exceeded 50 weight percent per solvent the film properties became worse.

In Table 27 and Table 28 alkylene glycol monoethers such as ethylene glycol monoethyl ether or ethylene glycol monobutyl ether were mixed with a solvent consisting of diethylene glycol diethyl ether, which is one of the compounds (I) and acetone, which is one of the compounds (II). From Table 27 and Table 28 it is recognized that sufficient film properties were maintained even when the amount of alkylene glycol monoether was twice of the total amount of diethylene glycol diethyl ether and acetone, and that was different from the results of the above-described case where butyl acetate was used.

Next, a mixed solvent consisting of the compounds (I), (II) and (III) was mixed with a generally used solvent for a manicure, and film properties were examined. The results are shown in Table 29.
