Description

Composition of Peel-off type aqueous Nail Polish}

It relates to a peel-off type aqueous nail polish composition having excellent lasting power.

Nail polish is used to beautifully decorate intrinsic dead skin cells such as hands and toenails, or for therapeutic treatment of hands and toenails.Acetone, alcohol as a solvent, camphor, ethyl benzoate as a plasticizer, etc. are added to the nitrocellulose or vinyl synthetic resin as a pigment. It is made by adding

Oil-based nail polish, which has been mainly used in the past, is not environmentally friendly because an organic solvent such as acetone is used as a solvent, and when applied to nails, it is not preferable because of the smell of organic solvents. In addition, since the nail polish using acetone has a risk of explosion and is vulnerable to heat, there is a risk of fire when the user carries it, so there are many restrictions on the place of use. In addition, acetone, which is used to remove oily nail polish, is classified as a dangerous material, and has a risk of fire and explosion. Due to this problem, interest in water-based nail polish having the same functions and effects as oil-based nail polish has increased without the need to use a remover.

On the other hand, since the water-based nail polish does not use an organic solvent, the above problems do not occur, and since it is a water-soluble composition, it is easy to remove and has the advantage of being hypoallergenic, and thus, interest in recent years is increasing. However, since the water-based nail polish product of the remover type is mainly composed of a product that simply mixes only a pigment and a thickener in a water-soluble PVA (polyvinyl acetic acid) emulsion solution, the color development power decrease due to the problem of pigment precipitation is a problem. Since the water resistance is weak by using the same single water-soluble resin, there is a problem that it is easily peeled off or damaged when water is repeatedly applied to the hand such as washing dishes or washing faces. In addition, in order to improve the feeling of use and drying speed, a low viscosity is required, so there is a problem of stability due to separation at high temperature.

One aspect is a first film forming agent (Film Forming Agent) comprising a polyurethane and an acrylate-based copolymer; And it is to provide a peel-off type aqueous nail polish composition comprising a second film forming agent (Film Forming Agent).

One aspect is a first film forming agent (Film Forming Agent) comprising a polyurethane and an acrylate-based copolymer; And it provides a peel-off type aqueous nail polish composition comprising a second film forming agent (Film Forming Agent).

As used herein, the term "nail polish" refers to an enamel-like liquid that is painted to add gloss or color to nails or toenails, and may be classified into water-based nail polish and oil-based nail polish. "Oil-based nail polish" is a nail polish based on an organic solvent and has a relatively excellent lasting power, but has a disadvantage in that it has a strong scent using an organic solvent and a remover such as acetone is required. In contrast, "aqueous nail polish" is a water-based nail polish and does not have the stimulating scent peculiar to oil-based nail polish.

As used herein, the term "peel off" is applied to nails and/or toenails to form a thin film, and while the film is formed, pigments bind to proteins that are constituents of nails and toenails to be colored. There is an advantage that it can be removed cleanly while minimizing irritation to nails and toenails without using a remover.

The acrylate-based copolymer may include all copolymers formed by polymerization of two or more acrylate-based monomers. The acrylate-based monomer may include, for example, acrylic acid, methacrylic acid, and salts, esters, and conjugate bases of derivatives thereof. Types of acrylate monomers include Acrylates, Methacrylates, Methyl acrylate, Ethyl acrylate, and 2-Chloroethyl vinyl ether. , 2-ethylhexyl acrylate (2-Ethylhexyl acrylate), hydroxyethyl methacrylate (Hydroxyethyl methacrylate), butyl acrylate (Butyl acrylate), butyl methacrylate (Butyl methacrylate), trimethylolpropane triacrylate (Trimethylolpropane triacrylate: TMPTA), and the like. The type of the salt may include, for example, sodium salt, ammonium salt, calcium salt, magnesium salt, and the like.

The acrylate-based copolymer may include not only an acrylate copolymer formed by polymerization of two or more monomers composed of acrylic acid, methacrylic acid or a simple ester thereof, but also various types of copolymers composed of acrylic acid and other monomers. . Copolymers of acrylic acid and other monomers include, for example, ammonium acrylate copolymer (Ammonium Acrylates Copolymer), ammonium VA/acrylate copolymer (Ammonium VA/Acrylates Copolymer), sodium acrylate copolymer (Sodium Acrylates Copolymer), Ethylene/Acrylic Acid Copolymer, Ethylene/Calcium Acrylate Copolymer, Ethylene/Magnesium Acrylate Copolymer, Ethylene/Sodium Acrylate Copolymer (Ethylene/Sodium Acrylate Copolymer), Ethylene/Zinc Acrylate Copolymer, Ethylene/Acrylic Acid/VA Copolymer, Acrylate/VP Copolymer (Acrylates/ VP Copolymer), Acrylates/VA Copolymer, Steareth-10 Allyl Ether/Acrylates Copolymer, Acrylates/ Steareth-50 Acrylic Rate copolymer (Acrylates/Steareth-50 Acrylate Copolymer), acrylate/Steareth-20 Methacrylate Copolymer (Acrylates/Steareth-20 Methacrylate Copolymer), acrylate/ammonium methacrylate copolymer (Acrylates/Ammonium Methacrylate) Copolymer), styrene/acrylate copolymer (Styrene/Acrylates Copolymer), styrene/acrylate/ammonium methacrylate copolymer (Styrene/Acrylates/Ammonium Methacrylate) Copolymer), ammonium styrene/acrylate copolymer (Ammonium Styrene/Acrylates Copolymer), sodium styrene/acrylate copolymer (Sodium Styrene/Acrylates Copolymer), acrylate/hydroxyester acrylate copolymer (Acrylates/Hydroxyesters Acrylates Copolymer) , Methacryloyl Ethyl Betaine/Acrylates Copolymer, Lauryl Acrylate/VA Copolymer, VA/Butyl Maleate/Isobornyl Acryl Rate Copolymer (VA/Butyl Maleate/Isobornyl Acrylate Copolymer), Ethylene/Methacrylate Copolymer, Vinyl Caprolactam/VP/Dimethylaminoethyl Methacrylate Copolymer (Vinyl Caprolactam/VP/Dimethylaminoethyl Methacrylate) Copolymer), Sodium Acrylates/Acrolein Copolymer, VP/Dimethylaminoethylmethacrylate Copolymer, and AMP-Acrylates Copolymer. Can include.

The acrylate-based copolymer may also include a polymer of acrylic acid and a salt thereof in a broad sense. Polymers of acrylic acid and its salts are, for example, polyacrylic acid, ammonium polyacrylate, potassium aluminum polyacrylate, potassium polyacrylate, sodium polyacrylate. (Sodium Polyacrylate), etc. may be included.

One or a combination of two or more of the acrylate-based copolymers may be used.

The acrylate-based copolymer is 0.5 to 10.0 wt%, 0.5 to 6.5 wt%, 0.5 to 9.0 wt%, 0.5 to 8.5 wt%, 0.5 to 7.0 wt%, 0.5 to 6.5 wt%, 0.5 to 5.0 wt%, 1.0 to 10.0 wt%, 1.0 to 9.5 wt%, 1.0 to 8.5 wt%, 1.0 to 7.0 wt%, 1.0 to 6.5 wt%, 1.0 to 6.0 wt%, or about 5.0 wt%. At this time, when the content of the acrylate-based copolymer is less than the above range, there may be a problem that the effect of improving the persistence of the nail polish decreases, and when it exceeds the above range, the gloss persistence may decrease as the content increases. Accordingly, the content of the acrylate-based copolymer may be appropriately selected in consideration of the lasting power and gloss lasting power of the nail polish.

The polyurethane and acrylate-based copolymer may be mixed in a ratio of 1:9 to 9:1. The polyurethane and acrylate-based copolymers are, for example, 1:9 to 9:1, 2:8 to 8:2, 7:3 to 3:7, 6:4 to 4:6, 1.5:8.5 to It may be mixed in a ratio of 8.5:1.5, 2.5:7.5 to 7.5:2.5, or 3.5:6.5 to 6.5:3.5. At this time, if the mixing ratio of the polyurethane and the acrylate copolymer is less than or exceeds the above range, the gloss retention of the nails decreases, the feeling of use is poor due to the increase in viscosity, and the peel-off power decreases. There is a problem in that the applied nail polish must be removed.

The film forming agent may be a water-soluble film forming agent. The water-soluble film forming agent may include all water-soluble components that form a film on the nail or toenail, for example, polyurethane (eg, polyurethane-10, polyurethane-11, polyurethane 15, polyurethane-40, etc.) ), polyvinylpyrrolidone, polyvinyl acetate, acrylamide copolymer, and the like. In one embodiment, the water-soluble film forming agent may be polyurethane. The water-soluble film forming agent may be included in 15 to 35% by weight, 20 to 30% by weight, 23 to 29% by weight, 25 to 27% by weight, or about 26% by weight based on the total weight of the composition.

The second film forming agent may be a mixture of a PPG-17/IPDI/DMPA copolymer and a diethylene glycol adipate IDPI (Diethylene glycol Adipate IPDI) copolymer. The PPG-17/IPDI/DMPA copolymer and the diethylene glycol adipate IDPI (Diethylene glycol Adipate IPDI) copolymer may be mixed in a ratio of 10:1 to 1:10. At this time, when the mixing ratio of the PPG-17/IPDI/DMPA copolymer and the Diethylene glycol Adipate IPDI (IDPI) copolymer is less than the above range, the adhesion between the nail polish and the nail decreases, resulting in a decrease in persistence. And if it exceeds the above range, there is a problem in that the initial glossiness is deteriorated and transformed into a matte phase.

The first film forming agent and the second film forming agent may be mixed in a ratio of 1:10 to 10:1. At this time, when the mixing ratio of the first film-forming agent and the second film-forming agent is less than the above range, the durability of the nail to the nail polish decreases, so that the front of the nail is abraded. When it exceeds the above range, the initial glossiness is reduced. There is a problem that the quality of the nail polish falls off.

In one embodiment, the composition may further include a thickener, a dispersant, an anti-settling agent, a film forming aid, and an antifoaming agent commonly used in cosmetics.

The thickener may include an inorganic thickener, a polysaccharide thickener, an anionic thickener, and the like, and the types thereof include Lithium Magnesium Sodium Silicate, Magnesium Aluminum Silicate, and aluminum silicate ( Aluminum Silicate), Calcium Silicate, Magnesium Silicate, Magnesium Trisilicate, Sodium Magnesium Silicate, Zirconium Silicate, and Lithium Magnesium Silicate ) Such as silicate inorganic thickener, Montmorillonite, Attapulgite, Bentonite, Fuller's Earth, Hectorite, Kaolin, Pyrophyllite ), zeolite, hyaluronic acid, xanthan gum, carrageenan, carbomer, and the like. In one embodiment, the thickener may be an inorganic thickener. In another embodiment, the thickener may be a silicate-based inorganic thickener. In another embodiment, the thickener may be maltodextrin.

The thickener may be included in an amount of 0.5 to 3.0% by weight, 0.5 to 2.5% by weight, 0.5 to 2.0% by weight, 0.5 to 1.5% by weight, 0.5 to 1.0% by weight, or about 0.7% by weight based on the total weight of the composition. If the content of the thickener is less than the above range, there may be a problem in that the pigment layer is separated, and if it exceeds the above range, the viscosity increases and the flowability disappears.

The dispersant is present between the pigment particles due to the interaction with the pigment due to the physicochemical molecular structure, thereby preventing agglomeration and re-aggregation between the pigment particles, and plays a role of ring mixing in the oil. The dispersant is, for example, polysorbate 60, vinylpyrrolidone / hexadecene copolymer (Vinylpyrrolidone / Hexadecene Copolymer), vinyl pyrrolidone / eicosine copolymer (Vinylpyrrolidone / Eicosene Copolymer), vinyl pi Rolidone/Vinylacetate Copolymer, Lauryl Polyglyceryl-3 Polydimethylsiloxyethyl Dimethicone, Polyhydroxystearic Acid, Dipenta Dipentaerythrityl Tri-Polydroxystearate, Dimer Dilinoleyl Hydrogenated Roginate, Dimer Dilinoleyl Dimer Dilinolate or Dimer Dilinol Rail diisostearate (Dimer Dilinoleyl Diisosteartae) may be included. In one embodiment, the dispersant may be polysorbate 60.

The dispersant may be included in an amount of 1.5 to 20% by weight and 3 to 15% by weight based on the total weight. If the content of the dispersant is less than the above range, there is a problem that the effect of improving dispersion stability is small, and if it exceeds the above range, the effect of improving dispersion stability is not significantly increased, and thus it may be inefficient.

The antifoaming agent serves to prevent or reduce the amount of foam formed on the surface of the liquid formulation, and the types include simethicone, dimethicone, polysiloxane, polydimethylsiloxane, polymethylphenylsiloxane, etc. It can, but is not limited thereto. In one embodiment, the antifoaming agent may be a silicone antifoaming agent. In another embodiment, the antifoaming agent may be simethicone.

The film forming aid functions to control drying and flow properties of the composition and to facilitate film formation. In addition, the film-forming aid helps the formation of the coating film and evaporates relatively quickly after the coating film is formed, thereby improving the strength of the coating film. The film forming aid is, for example, ethylene glycol monomethyl ether, ethylene glycol monobutyl ether, ethyl ene glycol monopropyl ether, diethylene glycol monomethyl ether, diethylene glycol monoethyl ether, diethylene glycol monobutyl ether, diethylene Glycol monopropyl ether, diethylene glycol monohexyl ether, propylene glycol monomethyl ether, propylene glycol monobutyl ether, propylene glycol monopropyl ether, propylene glycol phenyl ether, dipropylene glycol monomethyl ether, dipropylene glycol monobutyl ether or It may be dipropylene glycol monopropyl ether or the like.

The anti-settling agent is for preventing precipitation of pigment powder, etc., and may include lithium magnesium sodium silicate or tetra sodium Pyrophosphate.

The antifoaming agent is 0.01 to 0.2 wt%, 0.01 to 0.05 wt%, 0.03 to 0.1 wt%, 0.03 to 0.07 wt%, 0.03 to 0.05 wt%, 0.04 to 0.1 wt%, 0.04 to 0.06 wt%, based on the total weight of the composition, Alternatively, it may be included in about 0.05% by weight. If the content of the antifoaming agent is less than the above range, the degassing time may increase and the viscosity may increase, resulting in a problem of changing the formulation. If the amount of the antifoaming agent exceeds the above range, cratering or pinholes may occur, thereby deteriorating application properties.

The composition according to an embodiment may further include purified water. The purified water may mean water from which impurities have been removed through a filter or distillation, but is not limited thereto. The purified water is the main solvent used in the preparation of an aqueous nail polish composition, and can control viscosity and dryness. Unlike oil-based nail polish that uses organic solvents such as esters, ketones, alcohols, and hydrocarbons as the main solvent, the aqueous nail polish composition uses purified water as the main solvent, so it does not have a harsh scent, A nail polish composition that is harmless to can be prepared.

The purified water is 40 to 80 wt%, 40 to 75 wt%, 45 to 80 wt%, 45 to 75 wt%, 45 to 70 wt%, 50 to 80 wt%, 50 to 75 wt%, based on the total weight of the composition, 50 to 70 wt%, 55 to 80 wt%, 55 to 75 wt%, 55 to 70 wt%, 60 to 80 wt%, 60 to 75 wt%, 60 to 70 wt%, 65 to 80 wt%, or 65 It may be included in to 75% by weight. When the content of purified water is less than the above range, the viscosity of the aqueous nail polish composition becomes more than the appropriate viscosity, resulting in lower application properties, and when the content of the aqueous nail polish composition exceeds the above range, the viscosity of the aqueous nail polish composition is too low, making use difficult and storage stability may decrease. have.

The composition according to one embodiment may also contain additional ingredients commonly used in cosmetics, such as preservatives, colorants, fragrances, fillers, preservatives, neutralizing agents, sunscreens, sweeteners, vitamins, free-radical scavengers, sequestering agents, and Any conventional cosmetic ingredients that may be selected from mixtures thereof may further be included.

The composition according to one aspect contains a water-soluble acrylate film forming agent with excellent adhesion and durability, so that it can exhibit excellent lasting power and long-lasting effect with only one application, and when removed, it is in the form of a peel-off type film. Can be removed. In addition, the soft and light texture enables easy display, excellent color development and gloss, and evenly and evenly adheres without stickiness, so it can be quickly and firmly displayed.

[Experimental Example]

Sustainability Assessment

An experiment was conducted to evaluate the persistence of the nail polish compositions of Example 1 and Comparative Example 1. Specifically, each nail polish composition was provided to 10 consumers in their 20s to 30s. Before applying the nail polish, the test site (nail) was photographed with VISIA-CR (Canfield Scientific, Inc., U.S.A). After the application of the nail polish, immediately after (starting point), 1 day, 2 days, 4 days, 7 days after the same photo was taken. In addition, subjective efficacy evaluation was conducted through a questionnaire on persistence, and the results are shown in Table 3 below.

The evaluation for each item is based on a three-point method of maintaining persistence for 0 to 1 days (1 point), maintaining persistence for 2 to 3 days (2 points), and maintaining the formulation and persistence for 4 to 5 days (3 points). It was performed according to, and the lower the score, the lower the persistence.

Example 1 Comparative Example 1 vitality 3 One

As a result, as shown in Table 3, in the case of Comparative Example 1, the formulation was unstable, a separation phenomenon occurred, the drying speed was slow, and the problem of poor durability was confirmed. On the other hand, in the case of Example 1, it was confirmed that the persistence was maintained for 3 to 5 days. That is, the nail composition according to an embodiment includes PPG-17/IPDI/DMPA copolymer and diethylene glycol adipate IPDI corolimer, thereby improving adhesion to nails, and thus can last for a long time.

Adhesion and durability evaluation

The nail polish compositions of Example 1 and Comparative Example 2 were tested for adhesion and durability evaluation. The nail polish compositions of Example 1 and Comparative Example 2 were provided to five women in their 20s to 30s to apply them to nails. Thereafter, subjective efficacy evaluation was conducted through a questionnaire on adhesion and durability, and the results are shown in Table 4 below.

The evaluation of each item is to check whether the feeling of close contact is not felt or the scratch phenomenon (durability evaluation) appears after drying, or when it is scratched with a fingernail after drying (1 point). It was performed based on the three-point method of confirming (2 points), confirming the feeling of use and no scratch after drying (3 points), and the lower the score, the lower the durability.

Example 1 Comparative Example 2 Adhesion 3 One durability 3 2

As a result, as shown in Table 4, in the case of Comparative Example 2, it was confirmed that not only the feeling of use was reduced due to the decrease in the spreadability, but also the durability due to the occurrence of scratching occurred. On the other hand, in the case of Example 1, it was confirmed that adhesion was improved and durability was excellent. That is, the nail composition according to an exemplary embodiment can improve adhesion by containing an oily component, and increase durability by forming a hard film film by forming a network of polyurethane and acrylic copolymers.

Evaluation of gloss and peel off power

An experiment was conducted to evaluate the persistence of the nail polish compositions of Examples 1 to 5 and Comparative Example 1. Specifically, each nail polish composition was provided to 10 women in their 20s to 30s to apply the nail polish composition. Thereafter, subjective efficacy evaluation was conducted through a questionnaire on gloss and peel-off power, and the results are shown in Table 5 below.

Evaluation of each item is based on the three-point method: formulation is not maintained and gloss power is low (1 point), formulation is maintained but gloss power is low (2 points), and formulation and gloss power is maintained (3 points). It was performed, and the lower the score, the lower the glossiness.

Comparative Example 1 Example 1 Example 2 Example 3 Example 4 Example 5 Gloss 3 3 3 One 3 One Peel-off force 2 3 2 3 2 2

As a result, as shown in Table 5, in the case of Comparative Example 1, it was confirmed that the gloss power was good, but the peel-off power was poor. Examples 2 and 3 are according to the difference in the content of the PPG-17/IPDI/DMPA copolymer, and in the case of Example 3 in which the content of the composition is 10%, it was confirmed that the gloss decreased and the viscosity increased, thereby reducing the feeling of use. . On the other hand, in the case of Example 2, it was confirmed that the peel-off force was lower than that of Example 3. In addition, in the case of Examples 4 and 5, it was confirmed that the difference in the content of the Diethylene glycol Adipate IPDI copolymer, and when the composition was applied at 0.1%, the gloss and peel-off power were good, but the adhesion was lowered and the lasting power was poor. In the case, it was confirmed that the glossiness was significantly lowered. In the case of Example 1, it can be seen that the gloss and peel-off properties have an appropriate balance.

Adhesion evaluation

An experiment was conducted to evaluate the adhesion of the nail polish composition according to Example 2. First, after applying the composition of Example 2 to a glass plate substrate and drying it sufficiently for 1 hour, 11 parallel lines were drawn at intervals of parallel lines using a crosscutter device, and 11 parallel lines at equal intervals were drawn so as to intersect the parallel lines to make 100 squares. Thereafter, the composition was completely in close contact with the 3M transparent tape for 5 minutes, and then peeled off with a constant force. At this time, a peeling test was performed to investigate the number of peelings of 50% or more of the square inner coating film. At this time, other companies' products were used as a control.

2 is a photograph showing a result of comparing the adhesion of the nail polish composition according to Example 2 with other products and existing products of the company. As shown in FIG. 2, it was confirmed that the entire contents of the products of other companies and the company's existing products were peeled off. On the other hand, in the case of Example 2, it was confirmed that there was no peeling. That is, the composition according to the present invention has improved adhesion compared to the control group, so that the nail color may adhere for a long time.

Water resistance evaluation

An experiment was conducted to evaluate the water resistance of the nail polish composition according to Example 2. First, the composition was applied twice to the artificial nail, dried sufficiently for 1 hour, and then filled with water at about 25° C. to a height of 150 mm of the beaker and fixed. Thereafter, it was immersed at a height of about 120 mm for 1 hour and maintained for 8 hours to confirm swelling, cracking, peeling, etc. At this time, the products of other companies and the company's existing products were used as controls.

3 is a photograph showing a result of comparing the water resistance of the nail polish composition according to Example 2 with other products. As shown in FIG. 3, in the case of the company's existing products, peeling phenomenon was confirmed after 1 hour, and in the case of other products, swelling occurred after 8 hours, and it was confirmed that the surface condition was poor. On the other hand, in the case of Example 2, a phenomenon of peeling off from the tip of the artificial nail after 8 hours was observed, but it was confirmed that the difference was insufficient from immediately after application. That is, it can be seen that the composition according to the present invention has excellent water resistance compared to the control group.

The above description of the present invention is for illustrative purposes only, and those of ordinary skill in the art to which the present invention pertains will be able to understand that other specific forms can be easily modified without changing the technical spirit or essential features of the present invention will be. Therefore, it should be understood that the embodiments described above are illustrative in all respects and not limiting.
