Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improved enamel remover composition, and more specifically, it dissolves and removes nail enamel while exhibiting a disinfecting and sterilizing effect without damaging or bleaching nails during use. , relates to a non-flammable enamel remover composition capable of imparting a good glass-like gloss to nails.

Conventionally, enamel removers (nail enamel removers) include those based on organic solvents such as alcohol and lower alcohol esters, and those made of a combination of these hydrophilic organic solvents and water (water-miscible organic solvents). -water-based) is well known.

However, organic solvent-based glue movers can cause ignition, combustion, explosion, etc., as well as dissolving the pigments in clothing, damaging the surface of the nails by directly dissolving the moisture in the nails excessively and damaging the nail surfaces, and causing the nails to become white. There are fatal flaws such as posing risks such as

On the other hand, while the above-mentioned water-miscible organic solvent-water-based removers have little risk of ignition or explosion, many of them tend to combust when brought close to a flame or when brought into direct contact.
Further, drawbacks such as damage to nails and easy whitening have not been sufficiently improved. As a result of intensive research aimed at improving the shortcomings of the prior art, the present inventors have discovered that a composition in which phenoxyalkanol represented by the general formula shown below, an aliphatic lower alcohol, and water are melted together in appropriate amounts overcomes all the shortcomings of the above-mentioned enamel remover. The present invention was completed by discovering that an improved cage can also exhibit a disinfecting and sterilizing effect during use. The object of the present invention is to provide a novel, non-flammable product that can dissolve and remove nail enamel while exhibiting disinfecting and sterilizing effects without damaging nails or causing whitening during use, and that can impart a good glass-like luster to nails. Enamel remover compositions may also be provided.

That is, the present invention general formula (R is an alkyl group having 2 to 4 carbon atoms.

This is an improved enamel remover composition characterized in that the phenoxyalkanol represented by (), the aliphatic lower alcohol, and water are dissolved in water. Examples of the phenoxyalkanol represented by the above general formula used in the present invention include 2-phenoxyethyl alcohol, 3-phenoxypropyl alcohol, 2-phenoxypropyl alcohol, and 4-phenoxybutyl alcohol. can. Among them, 2-phenoxyethyl alcohol is most preferred. The phenoxyalkanol is
One or more may be used in combination. The above-mentioned phenoxyalkanol is a mucilage liquid with a light aroma that is sparingly soluble in water and easily soluble in alcohol, and is non-irritating or toxic to the human body, and has high disinfecting and sterilizing properties.
The amount (content) of the phenoxyalkanol used is 30 to 65% by weight, preferably 35 to 6% by weight, based on the total amount of the composition.

If it is less than 3% by weight, the effect of imparting a glass-like luster to nails during use, as well as the disinfection and sterilization effects, will likely decrease, and the nails will become white, and if it exceeds 65% by weight, the non-flammability will decrease (easily flammable). It is easy to cause deterioration in texture and feel.

Although phenoxyalkanol dissolves in water and has low hydrophilicity as described above, the coexistence of an aliphatic lower alcohol allows a relatively large amount of phenoxyalkanol to be stably mixed in to maintain a homogeneous system. Examples of the aliphatic lower alcohol used in the present invention include ethyl alcohol, n-butyl alcohol, and isobutyl alcohol.

One or more aliphatic lower alcohols are used in combination, and the amount (content) used is 15 to 4% by weight, preferably 20 to 35% by weight, based on the total amount of the composition. If it is less than 15% by weight, the solubility (falling) and feel of the nail enamel will be poor, and it will tend to form a non-uniform system, and if it is more than 4% by weight, it will be more likely to burn and the nails will be more likely to whiten during use. .

The amount of water used is 10 to 40% by weight based on the total amount of the composition,
Preferably it is 15 to 35% by weight. If it is less than 10% by weight, it becomes easily flammable, and if it is more than 4% by weight, the solubility of the nail enamel decreases, and the composition tends to form a heterogeneous system.

The enamel remover composition of the present invention may contain fragrances, colorants such as dyes, ultraviolet absorbers, and the like, if necessary. The enamel remover composition of the present invention is prepared by adding and mixing the above-mentioned phenoxyalkanol, aliphatic lower alcohol and water, or, if necessary, conventional additives such as fragrances, colorants, and ultraviolet absorbers in an appropriate order. Manufactured by

The enamel remover composition of the present invention is a novel composition in which the three components described above are mixed together, and it is a substantially transparent, uniform, nonflammable liquid, and has an appropriate degreasing power, so it can be used to remove nails. It does not cause harmful effects such as damaging nails or whitening, and while exhibiting a disinfecting and sterilizing effect, it can dissolve and remove nail enamel and at the same time give a good glass-like gloss.

In particular, aliphatic lower alcohols can be stably mixed with the phenoxyalkanol, which has low water miscibility, and by mixing an appropriate amount of phenoxyalkanol, all the above-mentioned drawbacks of organic solvent-based and aliphatic lower alcohol water-based removers can be improved. However, at the same time, the specificity of the effects of the present invention is remarkable, as it can impart a disinfecting and sterilizing effect and a good glass-like luster to melons, which are not seen in the above-mentioned removers.

Examples of the present invention will be described in detail below. In the examples, parts mean parts by weight, and % means weight %.

The performance test of the enamel remover sample was conducted using a specific nail enamel, and the results are shown in which 20 female panelists conducted the test every day for 3 weeks, and 3 professional technicians conducted the test every day for 3 weeks. The flammability of enamel remover is determined by the flame of a lighter (
Those that burned were placed in direct contact with the remover, and those that did not burn were considered non-flammable. Example 1 48 parts of 2-phenoxyethyl alcohol, 31 parts of ethyl alcohol, and 21 parts of water were placed in a mixer, and the three powders were mixed to obtain a transparent and uniform enamel remover of the present invention.

Next, they were mixed in the same manner as described above to obtain a remover of Comparative Example 1 consisting of 7 parts of ethyl alcohol and 21 parts of water, and a remover of Comparative Example 2 consisting of 21 parts of ethyl alcohol and 7 parts of water.

Furthermore, a remover of Comparative Example 3 was obtained using the same machine as the present invention except that diethylene glycol monophenyl ether was used as a related compound instead of 2-phenoxyethyl alcohol.

Table 1 shows the results of a practical test conducted by a panel of 20 women on the remover of the present invention and the removers of Comparative Examples 1 to 3.

Table 1 also shows the results of the flammability test of the mover, which was conducted by a professional engineer. Table 1 Test Item Inventive product Comparative example 1 Comparative example 2 Comparative example 3 Disinfection/sterilization effect
