Description

Nail makeup composition

The present invention relates to a nail makeup composition, and more particularly, to a nail makeup composition containing an arylsulfonamide epoxy resin and sucrose benzoate / suscrose acetate isobutylate butylbenzyl phthalate. It relates to a nail makeup composition having excellent physical properties and physiologically safe for skin and nails.

Generally, nail makeup products are made of nitrocellulose as the main film forming agent, and are composed of resins, plasticizers, solvents, and pigments. However, the physical properties of the resins among these components have a great influence on the coating properties of the nail lacquer products. Therefore, the selection of these resins is a big factor in determining the quality of nail makeup products. For these resins, the compatibility with nitrocellulose, the main film-forming agent, should be good and excellent gloss, appropriate hardness, adhesion to nails and water resistance In general, chemical stability, no change over time, and no harm to skin and nails are required.

However, conventionally used resins could not satisfy all of these requirements. For example, arylsulfonamide formaldehyde resin, which is widely used as a resin for nail lacquer, has relatively excellent properties in terms of physical properties, but is chemically unstable and decomposes in the presence of water or in a high humidity environment to formaldehyde, a strong skin irritant component. Or form over time form paraformaldehyde, which is a polymer of formaldehyde, and have a problem such as causing irritation and reducing the glossiness of the resin itself. In fact, commercially available nail makeup products containing formaldehyde-based resins contain formaldehyde, which is hundreds to thousands of ppm of toxic substances. In addition, phthalic acid-based alkyd resins are concerned about toxicity due to free phthalic acid, and when applied to products, they are not excellent in plasticity, glossiness, and nail makeup products with acrylic resins. A phenomenon in which a part of the applied coating film falls off is likely to occur.

Accordingly, the present inventors have conducted numerous experiments to improve the problems of the conventional resin, and when the arylsulfonamide epoxy resin and the sucrose benzoate / sucrose acetate isobutylate butylbenzyl phthalate copolymer are blended into the nail makeup composition, , Pigment dispersibility, abrasion resistance, adhesion, gloss, water resistance, heat resistance, light resistance, etc., compared to the case of using any conventional synthetic resin alone or in combination to form a nail makeup composition with higher physical properties and higher physiological safety The invention was completed.

In other words, the present invention is a nail makeup composition consisting of a film forming agent, a plasticizer, a solvent, a pigment, a resin, the arylsulfonamide epoxy resin and sucrose benzoate / sucrose acetate isobutylate butylbenzyl phthalate as a resin By using in combination, the object of the present invention is to form a coating film having excellent physical properties such as wear resistance, gloss and water resistance, and at the same time provide a physiologically safe nail makeup composition for skin and nails.

Hereinafter, the present invention will be described in detail.

The use amount of the arylsulfonamide epoxy resin used in the nail makeup composition of the present invention is preferably 5 to 25% by weight of the nail makeup composition, when the compounding amount is 7% by weight or less, sufficient adhesion, wear resistance, gloss It is difficult to obtain such effects, and when it is 20% or more, it has an undesirable effect on the dryness of the coating film and the wear resistance due to the decrease in the coating film hardness. Therefore, it is recommended to use 7 to 20% by weight to obtain proper gloss, adhesion, and water resistance. desirable.

In addition, when the content of sucrose benzoate / suscrose acetate isobutylate butylbenzyl phthalate copolymer is less than 0.5% by weight, it does not sufficiently exhibit the effect of sugar resin, and when it is more than 5% by weight, the dryness and water resistance of nail makeup products are inferior. , Since there is a risk of keratinization of the coating film, the content of 0.5 to 5% by weight is preferable, and in order to give effective adhesion, glossiness, and wear property to the nail makeup composition, the content of 1 to 4% by weight is more preferable.

Nitrocellulose used as a film-forming material in the present invention is RS 1/2 sec, RS 1/4 sec, RS 1/8 sec, etc., depending on the viscosity type, these may be used alone or in combination, but are generally commercially available Preference is given to using nitrocellulose in the wet state with 30% by weight of isopropyl alcohol in the range of 8-25% by weight. Too small amounts of nitrocellulose do not provide adequate viscosity and coating strength for nail lacquer products, and the coating is likely to be worn or scratched with little friction. On the contrary, when too much nitrocellulose is used, the coating film lacks flexibility, and even if a small impact is applied to the nails coated with nail lacquer, a part of the coating film easily falls off, and the drying speed is delayed and the viscosity is increased. The usability worsens due to the increase, making it difficult to form a preferred coating film.

In the present invention, as the plasticizer used to impart the flexibility of the coating film, citrate such as acetyl citrate, triethyl acetyl citrate, phosphate such as tricresyl phosphate and tributyl phosphate, dioctyl phthalate, etc. It is possible to use mixed, and it is preferable to use 1.5-8 weight% with respect to the whole nail lacquer composition.

As the solvent used in the nail makeup composition, lower ester solvents such as ethyl acetate, butyl acetate and amyl acetate, alcohols such as ethyl alcohol, butyl alcohol and isopropyl alcohol, toluene and the like can be used. The content is determined in consideration of the dissolving power, drying rate, usability, etc. to nitrocellulose, but it is usually preferred to use 50-80% by weight based on the total amount of nail lacquer.

In addition, red No. 201, red No. 202, red No. 220 Yellow No. 4 aluminum lake, titanium dioxide, bismuth oxychloride, mica titanium, guanine, discoloration inhibitor, stealconium hectorite, etc., which are commonly used as nail lacquer ingredients It can be used in addition to the nail makeup composition of the present invention for the purpose of preventing, discoloration prevention, pigmentation prevention and the like.

The nail makeup composition of the present invention composed of the composition as described above is an arylsulfonamide epoxy resin and sucrose benzoate / sucrose acetate isobutylate butylbenzyl phthalate copolymer as shown in Table 3 and Table 6 of the following examples By using the mixture, it has superior characteristics in all the functions to be provided as nail makeup, such as the durability of the film, the wear resistance, the compatibility with the solvent and the nitrocellulose, the gloss, the light resistance, the heat resistance and the usability. In addition, it is a nail makeup composition having high physiological stability to skin and nails because it does not contain any toxic substances such as glass formaldehyde contained in the conventional nail makeup resin.

Hereinafter, the present invention will be described in more detail with reference to Examples and Comparative Examples.
