Description

Water soluble nail polish composition comprising soap base

It relates to an aqueous nail polish composition comprising a film forming agent and a saponifying base.

In recent years, nail polish has become more common than face makeup and has become a basic makeup framework that anyone can easily access. In other words, nail polish is available in a variety of colors, making nails beautiful, and has become an essential item that makes women's appearance stand out as if they were touching skin care products on the skin.

Conventional nail polishes use nitrocellulose and plasticizers as film-forming agents, and various organic solvents such as toluene are mainly used. However, these organic solvents are treated as a product group that causes environmental hormones, and may cause physical problems such as headaches in an enclosed space as well as safety problems such as fire or explosion. In addition, the product that removes it also has the disadvantage of indispensably using an organic solvent such as acetone. Therefore, it is urgent to develop a manicure that is harmless to the human body and is hygienic and eco-friendly, and the most common acrylic polymer has been grafted to replace the film effect of nitrocellulose. However, since it may not be readily acceptable to certain consumers that bases made of acrylic polymers should be removed with components such as ethanol, the need to develop a base that can be removed without using a solvent during cleansing has been raised. come.

Therefore, it is necessary to develop a water-dispersible nail polish that uses an acrylic polymer having water resistance at the level of water resistance in daily life as a main polymer, and is easily removed when reacting to cleansing products such as soap.

One aspect relates to an aqueous nail polish composition comprising a film-forming agent and a saponifying base.

One aspect provides an aqueous nail polish composition comprising a film former and a saponifying base.

As used herein, the term "nail polish" refers to an enamel-like liquid applied to add gloss or color to nails or toenails, and may be classified into aqueous nail polish and oil 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. However, among the water-soluble nail polish formulations, the peel-off type has a disadvantage in that the film is hard, but can be separated if left in water for a long time, and can be removed according to a certain level of friction during daily life. In addition, the wash-off type has a disadvantage in that it melts easily when friction occurs under water conditions, so the long lasting effect is inferior.

Therefore, the composition maintains the effect as a nail polish under a certain level of water conditions, and reacts to a cleansing product such as soap by including a saponification base, which is a mixture of a fatty acid and an alkali neutralizing agent, so that it can be easily removed without a separate remover. There is an advantage.

In one embodiment, the saponification base may be a mixture of a fatty acid and a neutralizing agent. The fatty acid may be stearic acid, lauric acid, myristic acid, palmitic acid, or a combination thereof. The fatty acid may have 14 to 22 carbon atoms. The number of carbon atoms may be, for example, 14 to 22, 14 to 20, 14 to 18, 15 to 21, 15 to 19, or 16 to 18. At this time, when the number of carbon atoms of the fatty acid is less than or exceeds the above range, there is a problem that the properties or state of the soap may change. In addition, the neutralizing agent is a material capable of supplying counter ions (cations) that neutralize anions of fatty acids, and may be inorganic salts, organic salts, cationic polymers, etc. that can be blended into cosmetics. The neutralizing agent may be, for example, tromethamine, triethanolamine, AMPD, arginine, potassium hydroxide (KOH), and sodium hydroxide (NaOH), or a combination thereof.

In the present specification, the term "neutralization ratio" or "neutralization rate" refers to a ratio of a fatty acid neutralized by a neutralizing agent, and the saponification base may be a neutralization reaction by adding a neutralizing agent in a certain content ratio to the fatty acid. In one embodiment, the neutralization rate may be 30 to 100%. The neutralization rate may be, for example, 30 to 100%, 40 to 100%, 50 to 100%, 60 to 100%, 70 to 100%, 80 to 100%, or 90 to 100%. At this time, when the neutralization rate is less than the above range, there is a problem that the fatty acid may precipitate or the surface may become unstable after application of the nail polish due to the presence of residual fatty acids, and when it exceeds the above range, the water resistance of the nail polish composition decreases. have.

The saponification base may be included in an amount of 0.01 to 30% by weight of the total composition. The saponification base is, for example, 0.01 to 30% by weight, 0.01 to 25% by weight, 0.01 to 20% by weight, 0.01 to 15% by weight, 1 to 15% by weight, 1 to 10% by weight, 5 to 20% by weight, It may be included in 5 to 15% by weight, 5 to 10% by weight, 7 to 13% by weight, or 10 to 20% by weight. At this time, if the content of the saponification base is less than the above range, there is a problem that the nail polish composition cannot be sufficiently removed by a cleansing product such as soap, and if it exceeds the above range, the drying speed of the nail polish is slowed down or under daily living conditions. There is a problem that it cannot last for a long time because it is removed too easily.

In one embodiment, the film forming agent may be an acrylate-based copolymer. The acrylate-based copolymer is, for example, an ammonium acrylate copolymer, an ammonium acrylate copolymer, an ammonium VA/acrylate copolymer, a sodium acrylate copolymer, an ethylene/acrylic acid copolymer, an ethylene/calcium acrylate copolymer Coalescence, ethylene/magnesium acrylate copolymer, ethylene/sodium acrylate copolymer, ethylene/zinc acrylate copolymer, ethylene/acrylic acid/VA copolymer, acrylate/VP copolymer, acrylate/VA copolymer, Steareth-10 allyl ether/acrylate copolymer, acrylate/steareth-50 acrylate copolymer, acrylate/steareth-20 methacrylate copolymer, acrylate/ammonium methacrylate copolymer, Styrene/acrylate copolymer, styrene/acrylate/ammonium methacrylate copolymer, ammonium styrene/acrylate copolymer, sodium styrene/acrylate copolymer, acrylate/hydroxyester acrylate copolymer, methacryloyl Ethyl betaine/acrylate copolymer, lauryl acrylate/VA copolymer, VA/butyl maleate/isobornyl acrylate copolymer, ethylene/methacrylate copolymer, vinyl caprolactam/VP/dimethylamino It may be an ethyl methacrylate copolymer, a sodium acrylate/acrolein copolymer, a VP/dimethylaminoethyl methacrylate copolymer, an AMP-acrylate copolymer, or a combination thereof. In one embodiment, the acrylate-based copolymer may be a dispersion type or an emulsion type, and may include a water-soluble film forming agent for differentiation in usability or effect. 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 film forming agent may be included in an amount of 10 to 40% by weight of the total composition. The content of the film forming agent is, for example, 10 to 40% by weight, 10 to 35% by weight, 10 to 30% by weight, 10 to 25% by weight, 10 to 20% by weight, 15 to 40% by weight, 15 to 30 It may be weight percent, 20 to 40 weight percent, or 20 to 30 weight percent. At this time, when the content of the film forming agent is less than the above range, there is a problem in that the effect of improving the persistence of the nail polish decreases, and when it exceeds the above range, the nail polish composition dries too quickly, which may cause problems in application or storage stability.

The composition according to an embodiment may further include any one or more components selected from the group consisting of a dispersant, a thickener, and an antifoam. The dispersant improves the dispersibility of the composition and increases dispersion stability to prevent re-aggregation after dispersion, and any commonly available anionic, nonionic or amphoteric surfactant may be used. . The HLB (Hydrophile-Lipophile Balance) value of the dispersant is not particularly limited, but may be 8 or more, specifically 10 or more. The types include polysorbate-60, polysorbate-80, polysorbate-85, PEG-7 olivate, PEG-8 oleate, polyglyceryl-3 methylglucose distearate, oleth-10, Oleth-10/polyoxyl 10 oleyl ester, PEG-8 laurate, isosteareth-20, PEG-60 almond glyceride, PEG-20 methyl glucose sesquistearate, ceteareth-20, oleth- 20, steareth-20, steareth-21, cereth-20, isoseteth-20, and the like. The dispersant is 0.5 to 5.0 wt%, 0.5 to 4.0 wt%, 0.5 to 3.0 wt%, 1.0 to 5.0 wt%, 1.0 to 4.0 wt%, 1.0 to 3.0 wt%, 1.5 to 2.5 wt%, based on the total weight of the composition, Or it may be included in about 2.0% by weight.

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, 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. 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. When the content of the thickener is less than 0.5% by weight, a problem of layer separation may occur, and when the content of the thickener is more than 3.0% by weight, the viscosity increases and flowability disappears.

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 antifoaming agent is 0.01 to 0.1 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. When the content of the antifoaming agent is less than 0.01% by weight, the degassing time increases and the viscosity increases, resulting in a problem of changing the formulation, and when it exceeds 0.1% by weight, cratering or pinholes may occur, resulting in deterioration of spreadability.

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. 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. At this time, when the content of the purified water is less than the above range, the viscosity of the aqueous nail polish composition is higher than the appropriate viscosity, resulting in lower application properties, and when the content exceeds the above range, the viscosity of the aqueous nail polish composition is too low, making use difficult and storage stability may decrease. I can.

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 aqueous nail polish composition may be commercialized as an aqueous nail polish product, and the preparation of the aqueous nail polish may be performed according to a conventional method.

[Production Example]

Manufacturing Examples 1-5. Preparation of saponification base

A saponification base was prepared with the ingredients and contents shown in Table 1 below. Specifically, a saponification base was prepared by adding and dissolving a fatty acid in purified water at 80° C., and then adding a neutralizing agent previously dissolved in purified water. At this time, the neutralization ratio of the neutralizing agent for saponification was set to 55%, 70%, 85%, 100% and 115%, respectively. Unless stated otherwise herein, component content is in weight percent.

ingredient Content (% by weight) Manufacturing Example 1 Manufacturing Example 2 Manufacturing Example 3 Manufacturing Example 4 Manufacturing Example 5 water 87.66 87.02 86.38 85.75 85.1 Stearic Acid 10 10 10 10 10 Tromethamine 2.34 2.98 3.62 4.25 4.9

As a result, Preparation Examples 1 and 2 showed a thin or low viscosity state, and it could be observed that the pearly feeling of fatty acids floated. This was excluded from subsequent experiments because it may precipitate as crystals or precipitation may occur over time. In addition, Preparation Example 5 was excluded from the experiment since there was a problem in that it was difficult to base the reaction due to no reaction after a certain amount of addition of the neutralizing agent.

On the other hand, it was confirmed that Preparation Examples 3 and 4 exhibited a creamy viscosity at a convenient level. However, about a week after preparing the saponification base, crystals that appeared to be residual fatty acids in Preparation Example 3 could be confirmed. Therefore, the experiment was performed on the basis of Preparation Example 4 in which crystals were not precipitated while showing a convenient creamy viscosity.

Manufacturing Examples 6-10. Preparation of saponification base

In order to prepare a nail polish composition, the saponification base content of Preparation Example 4 was determined. The components and contents shown in Table 2 below were prepared by varying the content of stearic acid so that the neutralization ratio was 100%.

As a result, in the case of Preparation Examples 6 and 7, the low-viscosity dilute saponification base was shown, and in the case of Preparation Examples 9 and 10, it was confirmed that the high viscosity or a part of the crystallization was already formed during the addition of tromethaamine. Therefore, it was determined that the saponification base of Preparation Example 8 was most suitable.

Example 1 and Comparative Examples 1 to 4. Preparation of nail polish composition

The nail polish compositions of Example 1 and Comparative Examples 1 to 4 were prepared with the components and contents shown in Table 3 below. First, the viscosity was increased by adding montmorillonite, an inorganic thickener, to a dispersion-type acrylate copolymer film forming agent having a transparent property. Thereafter, the saponification base of Preparation Example 8 was added and stirred, a dispersing agent, an antifoaming agent, and a preservative were added and sufficiently stirred, and then filtered through a degassing process.

[Experimental Example]

Check viscosity properties

The viscosity characteristics of the nail polish compositions prepared in Example 1 and Comparative Examples 1 to 4 were confirmed. Specifically, the nail polish compositions prepared in Example 1 and Comparative Examples 1 to 4 were stored in a 100 ml sample container, and then left in a constant temperature bath at 25° C. for about 1 hour. Thereafter, a Rheometer LVT viscometer was used, and the viscosity was measured for 1 minute at a rotation speed of 30 rpm using a #3 Pin.

Example 1 Comparative Example 1 Comparative Example 2 Comparative Example 3 Comparative Example 4 Viscosity 1,500 cps 4,000 cps 2,360 cps 720 cps 470 cps

As a result, as shown in Table 4, in the case of Comparative Example 1, the viscosity itself was very high, and the phenomenon of grain formation occurred when applied to the nail, and in Comparative Examples 3 and 4, which had low viscosity, the coating power was weak and the nail surface was reflected The phenomenon appeared. On the other hand, in the case of Example 1 and Comparative Example 2, it was confirmed that the viscosity of an appropriate level was measured to have excellent application properties as an aqueous nail polish composition.

Detergency check

The cleaning power of the nail polish compositions prepared in Example 1 and Comparative Examples 1 to 4 was confirmed. Specifically, each nail polish composition was provided to 10 female consumers in their 20s to 30s, and then applied to the test site (nail). After drying for 12 hours, water was applied. After that, rubbing it like a massage with soap, and after about 30 seconds, rinsed with running water. Subjective evaluation of efficacy was conducted through a questionnaire on cleaning power.

Example 1 Comparative Example 1 Comparative Example 2 Comparative Example 3 Comparative Example 4 Cleaning power ○ × △ ◎ ◎

◎: Very good

○: Excellent

△: Normal

×: weak

As a result, as shown in Table 5, in the case of Comparative Example 1, the nail composition was hardly removed, and in the case of Comparative Example 2, it was confirmed that the color oozes out from the time of rubbing with soap, but not all of them.

On the other hand, in the case of Example 1, as shown in FIG. 1B, a phenomenon in which the color oozes from when rubbed with soap appeared. In addition, as shown in Fig. 1c, it was confirmed that all of them were removed when rubbed with flowing water. In the case of Comparative Examples 3 to 4, after applying the nail polish, the color gradually oozes out even though only water was applied in a dried state. It seems that the water resistance of Comparative Examples 3 to 4 is weak because the content of the saponification base is excessively contained in the compositions of Comparative Examples 3 to 4 compared to the composition of Example 1. That is, it can be seen that the saponification base included in the composition meets with the surfactant included in the soap or cleansing product and becomes a state in which it can be easily dissolved, and dissociates from the moment it contacts water. In addition, when the saponification base is excessively included, the water resistance is deteriorated, and thus the water resistance in daily life such as light hand washing is poor, and thus the persistence of the nail polish may decrease. Accordingly, the composition according to an aspect can be waterproofed to life by including a saponification base of a certain level, thus exhibiting persistence, and can be easily removed by reacting with a cleansing product such as soap without a separate remover.

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 it can be easily modified into other specific forms 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.
