Description

Composition for enhancing gloss of aqueous nail polish

Technical Field

The present disclosure relates to a composition for enhancing the gloss of aqueous nail polishes.

Background

Nail polish is used for fine decoration of real cutin such as fingernails and toenails, or for treatment in treatment of fingernails and toenails, and is made by putting acetone, ethanol, and camphor and ethyl benzoate, etc. as solvents, and adding pigments, in nitrocellulose or vinyl synthetic resin.

The currently mainly used oil-based nail polish is not preferable because it is not environment-friendly using an organic solvent such as acetone, and gives off much odor of the organic solvent when applied on fingernails. In addition, since the nail polish using acetone has a risk of explosion and is easily heated, the user has a risk of fire when carrying it, thus having many restrictions on the use place.

On the one hand, since the aqueous nail polish does not cause the above problems without using an organic solvent and is a water-soluble composition, it is easy to remove and has an advantage of low irritation, and has received increasing attention in recent years. However, although gloss and physical properties are excellent when the resin is used alone in the aqueous nail polish, there is a problem that gloss is reduced when additives other than the resin or inorganic/organic pigments are added.

Therefore, there is a need to develop a gloss agent for maintaining and improving gloss when using other additives than resin and inorganic/organic pigments in aqueous nail enamel.

Disclosure of Invention

Technical problem

In one aspect, a composition for enhancing the gloss of an aqueous nail polish is provided, comprising a polysaccharide as a gloss agent.

Another aspect provides an aqueous nail polish composition including the composition for enhancing the gloss of aqueous nail polish.

Technical scheme

In one aspect, a composition for enhancing the gloss of an aqueous nail polish is provided, which comprises a saccharide, specifically, a polysaccharide as a gloss agent.

The term "nail polish (nail polish)" refers to an enamel-like liquid used to add gloss or color to nails or toenails, and may be classified into aqueous nail polishes and oil nail polishes. An "oil nail polish" is a nail polish based on an organic solvent, which has relatively excellent staying power, however, it has the disadvantages of emitting a strong odor using an organic solvent and requiring a remover such as acetone. In contrast, "aqueous nail polish" is a water-based nail polish that is free of the pungent odor characteristic of oil nail polishes and can be easily removed without the use of a remover such as acetone. Although the existing aqueous nail polish has these advantages, it has a problem that gloss is reduced when other additives and pigments, etc. other than the resin are added. Thus, a composition using saccharides, particularly polysaccharides, as a gloss agent is provided to enhance the gloss of an aqueous nail polish.

In the present disclosure, "enhancing the gloss of the aqueous nail polish" means not only enhancing the gloss of the aqueous nail polish, but also may include maintaining the gloss of the aqueous nail polish reduced by adding additives, inorganic pigments, organic pigments, etc. before the reduction or improving the gloss.

The saccharide may include a compound used as a sweetener (sweeener). The "sweetener" refers to a flavoring or additive that produces a sweet taste. Sweeteners are commonly used for addition to food to increase the sweetness of food, but a new use as a gloss agent when added to an aqueous nail polish is identified to complete the present disclosure.

The "saccharide (saccharide)" refers to a saccharide in a broad sense and includes all of monosaccharides, disaccharides, oligosaccharides, polysaccharides, sugar derivatives, sugar alcohols (sugar alcohols), and the like. The saccharides may include all carbohydrate-based saccharides and non-carbohydrate-based saccharides. Among the carbohydrate-based saccharides, recent progress in enzyme production technology using starch as a raw material has led to the continuous emergence of new species. The non-carbohydrate based saccharide may include all glycosides (glycosides) produced by combining a sugar (sugar) with a non-carbohydrate ingredient or enzyme-treated products thereof, amino acid based saccharides, and the like. The non-carbohydrate based saccharides may be naturally derived or synthetic.

The monosaccharide is the smallest unit of sugar that can no longer be decomposed by hydrolysis, which includes an aldehyde group (-CHO) or ketone (-CO-) having a hydroxyl group and a carbonyl group, or a derivative thereof, and is generally in a cyclic arrangement. The monosaccharide may include 3 to 7 carbon atoms. The monosaccharides may include glucose, fructose, and the like.

The disaccharide is a compound synthesized by dehydrating two monosaccharides. The disaccharides may include lactose, maltose, sucrose, and the like. The oligosaccharide may include galacto-oligosaccharide, maltoheptaose, isomaltheptaose, cyclodextrin, oligo-saccharide, fructo-oligosaccharide, soy oligosaccharide, and the like.

The sugar derivative may include a coupling sugar, isomaltulose, and the like.

The sugar alcohol may include sorbitol (sorbitol), erythritol (erythritol), mannitol (mannitol), xylitol (xylitol), and the like.

The "polysaccharide (polysaccharide)" is a general term for saccharides in which three or more monosaccharides form macromolecules via glycosidic bonds. The polysaccharides may include all of carbohydrate-based polysaccharides, non-carbohydrate-based polysaccharides, and the like.

The naturally derived non-carbohydrate based polysaccharides may include stevioside (stevia), rubusoside, curculin (curculin), phyllodulcin (phylloducin), glycyrrhetinic acid (glycyrrhetic acid), monellin (monellin), thaumatin (thaumatin), and the like.

The synthetic non-carbohydrate based polysaccharides may include saccharin (saccharorin), sucralose (sucralose), cyclamate (cyclamate), aspartame (asparatam), Alitame (Alitame), and acesulfame potassium (acesulfame).

According to one embodiment, the composition for enhancing the gloss of an aqueous nail polish may include saccharides, specifically, one or two or more polysaccharides.

According to another example, the polysaccharide may use maltodextrin and stevioside, but is not limited thereto. The case of using maltodextrin and stevioside together can more improve glossiness than the case of using maltodextrin alone. In addition, the case of using maltodextrin and stevioside together may have a faster drying speed than the case of using maltodextrin alone. Therefore, the simultaneous use of maltodextrin and stevioside may have more excellent characteristics in gloss enhancing effect and drying speed than the case of using maltodextrin or stevioside alone.

The "maltodextrin (maltodextrine)" is a generic name of low-molecular dextrin which has a lower degree of polymerization than that of achromatic dextrin and is between before becoming maltose among dextrins produced by decomposing starch with dilute acid or amylase, and has various structures and properties according to the production method, and the degree of polymerization is generally about 3 to 6 degrees. In other words, it may refer to maltose, maltotriose and the polymeric homologous series thereof. A polymerization degree of 3 is called maltotriose, a polymerization degree of 4 is called maltotetraose, a polymerization degree of 5 is called maltopentaose, and a polymerization degree of 6 is called maltohexaose.

The "stevioside" is a glycoside contained in the leaf or stem of Stevia rebaudiana (Stevia rebaudiana) which is a perennial plant of the family Compositae, and is a natural sweetener having a sweetness of about 300 times that of sugar with a low calorie.

The polysaccharides are included, for example, in an amount of 1 to 50 wt%, 1 to 45 wt%, 1 to 40 wt%, 1 to 35 wt%, 1 to 30 wt%, 1 to 25 wt%, 1 to 20 wt%, 5 to 50 wt%, 4 to 45 wt%, 5 to 40 wt%, 5 to 35 wt%, 5 to 30 wt%, 5 to 25 wt%, 5 to 20 wt%, 10 to 45 wt%, 10 to 40 wt%, 10 to 35 wt%, 10 to 20 wt%, 15 to 50 wt%, 15 to 45 wt%, 15 to 40 wt%, 15 to 35 wt%, 15 to 30 wt%, 15 to 25 wt%, or a combination thereof, based on the total weight of the composition, 15 to 20 weight percent, 20 to 50 weight percent, 20 to 45 weight percent, 20 to 40 weight percent, 20 to 35 weight percent, 20 to 30 weight percent, 20 to 25 weight percent, 25 to 50 weight percent, 25 to 45 weight percent, 25 to 40 weight percent, 25 to 35 weight percent, 25 to 30 weight percent, 30 to 50 weight percent, 30 to 45 weight percent, 30 to 40 weight percent, 30 to 35 weight percent, 35 to 50 weight percent, 35 to 45 weight percent, 35 to 40 weight percent, or about 40 weight percent, but is not limited thereto. When the content of the polysaccharide is 10 to 20% by weight, a significant effect is exhibited in terms of drying speed and gloss, and this value may be smaller than that when the content of the polysaccharide is 35 to 45% by weight. When the content of the polysaccharide is 20 to 35% by weight, low values of gloss and drying speed are shown, and when the content of the polysaccharide is more than 45% by weight, too high viscosity affects the feeling in use. Therefore, when the content of the polysaccharide is 35 to 45% by weight, it is preferable because it has excellent gloss and drying speed and appropriate viscosity.

The weight ratio of maltodextrin to stevioside can be from 1:10 to 10:1, 1:5 to 5:1, or 1:4 to 4:1, specifically, about 1:10, about 1:9, about 1:8, about 1:7, about 1:6, about 1:5, about 1:4, about 1:3, about 1:2, about 1:1, about 2:1, about 3:1, about 4:1, about 5:1, about 6:1, about 7:1, about 8:1, about 9: 1, or about 10:1, but is not limited thereto. According to an embodiment, the weight ratio of maltodextrin to stevioside may be about 1:1. When the weight ratio of maltodextrin to stevioside is about 1:1, an aqueous nail polish excellent in gloss, fast in drying speed, and appropriate in viscosity to have excellent physical properties can be manufactured.

Another aspect provides an aqueous nail polish composition including the composition for enhancing the gloss of an aqueous nail polish.

The composition for enhancing the gloss of an aqueous nail polish may be included in an amount such as, but not limited to, 1 to 20 wt%, 1 to 15 wt%, 1 to 10 wt%, 2 to 20 wt%, 2 to 15 wt%, 2 to 10 wt%, 5 to 20 wt%, 5 to 15 wt%, 5 to 10 wt%, or about 7 wt%, based on the total weight of the composition. When the content of the composition for enhancing the gloss of an aqueous nail polish is low beyond the above range, there may be a small effect of enhancing the gloss, and when the content of the composition for enhancing the gloss of an aqueous nail polish is high beyond the above range, the drying speed is slow and the viscosity is high, which may not be suitable for use as a nail polish.

The aqueous nail polish composition may have a gloss of the following gloss units, such as 70 or greater, 70 to 99, 70 to 90, 75 to 90, or 80 to 90. The gloss can be measured by the bick Gardner (BYK Gardner) gloss agent.

The drying speed of the aqueous nail polish composition may be a time such as, but not limited to, 10 minutes or less, seconds or more to 10 minutes or less, 1 minute to 10 minutes, 1 minute to 8 minutes, minutes to 10 minutes, or 5 minutes to 8 minutes. The "drying speed" may refer to a time from a time point based on application to the fingernail or toenail until completely dried and not stuck.

The aqueous nail polish composition may have a viscosity of 4000cps or less, 2000cps to 4000cps, or 2000cps to 3500cps, but is not limited thereto. The viscosity can be measured by means of a Bohler fly (Brookfield) viscometer at a speed of 60 rpm.

The aqueous nail polish composition according to an embodiment may further include ingredients generally used in aqueous nail polish compositions, for example, may further include a water-soluble resin, a water-soluble film forming agent, purified water, and the like.

The water-soluble resin is not limited in kind as long as it is a water-soluble resin generally used in an aqueous nail polish composition, and specifically, a water-soluble acrylic resin, for example, ammonium acrylate copolymer (ammonium acrylate copolymer) may be used.

The aqueous nail polish composition according to an embodiment may further comprise a dispersant and a defoamer.

The kind of the dispersant is not limited as long as it is a dispersant generally used in an aqueous nail polish composition, and specifically, polysorbate-60, polysorbate-80, polysorbate-85, PEG-7 olive oleate, PEG-8 oleate, polyglycerol-3 methylglucdistearate, oleyl-10/10 polyethylene glycol oleyl ether, PEG-8 laurate, isostearyl-20, PEG-60 almond oil glycerides, methylgluco-hemistearate, ceteareth-20, oleyl-20, steareth-21, ceteth-20, and isocetylpolyether-20, etc., for example, polysorbate-60 may be used.

The type of the defoaming agent is not limited as long as it is a defoaming agent generally used in an aqueous nail polish composition, and specifically, a silicon-based defoaming agent such as Simethicone (Simethicone), Dimethicone (Dimethicone), Octoxynol (Octoxynol), polysiloxane, polydimethylsiloxane, polyphenylmethylsiloxane, and fluoropolysiloxane may be used, and for example, Simethicone may be used.

The purified water may refer to water from which impurities are removed by a filter or distillation, but is not limited thereto. The purified water is a main solvent for preparing the aqueous nail polish composition, and can control viscosity and dryness. In the case of an oil-based nail polish, organic solvents such as ester-based, ketone-based, alcohol-based, and hydrocarbon-based solvents are used as main solvents, whereas in contrast, since the aqueous nail polish composition uses purified water as a main solvent, not only does it not emit unpleasant odor, but also it is possible to manufacture a nail polish composition that is not harmful to humans and the environment.

The aqueous nail polish composition according to an embodiment may be used for various purposes such as, but not limited to, a nail primer and a nail top coat.

The composition according to an embodiment may further comprise additional ingredients commonly used in cosmetics, for example, any conventional cosmetic ingredients selected from preservatives, pigments, fragrances, fillers, preservatives, neutralizers, uv blockers, vitamins, free-radical scavengers, metal ion chelators, and mixtures thereof.

In some embodiments, the value may change by 5%, 2%, or 1%. For example, "about 5(about 5)" is meant to include any value between 4.5 and 5.5, between 4.75 and 5.25, between 4.9 and 5.1, or between 4.95 and 5.05.

Expressions such as "having," "may have," "include," or "may include," etc., may indicate the presence of corresponding features (e.g., numerical values or components such as components), but do not preclude the presence of additional features.

Detailed Description

Hereinafter, the present disclosure will be described in more detail by examples. However, these examples are merely illustrative of the present disclosure, and the scope of the present disclosure is not limited to these examples.

Comparative examples 1 to 5 preparation of brightener compositions for aqueous nail polishes

As for the ingredients shown in table 1 below, purified water was first weighed in a beaker (80 ℃ to 90 ℃), and then stirred at 100rpm using a fixed mixer (agimizer), and glucosyl steviol glycoside, stevioside, or maltodextrin was put therein, and then uniformly mixed for 3 minutes. After mixing, the thickener was sprayed and dropped, stirred while increasing the rpm at 200 to 300rpm as the viscosity increased, and uniformly mixed for 5 minutes. Thereafter, the preservative was set down and stirred for 5 minutes to produce a gloss composition. As a result, in comparative example 1, a deep yellow gel-like composition was obtained. In comparative examples 2 and 3, pale yellow transparent gel-like compositions were obtained. In comparative examples 4 and 5, transparent gel-like compositions were obtained. Table 1 below shows specific ingredients and contents of the gloss agent compositions according to comparative examples 1 to 5. Unless otherwise indicated herein, the ingredient content is in weight percent.

Test example 1 evaluation of viscosity, drying speed and gloss

Tests for evaluating viscosity, drying speed, and gloss were performed on the aqueous nail polish compositions of comparative manufacturing examples 1 to 5.

Specifically, the viscosity was measured by a Bohler fly (Brookfield) viscometer No. two needle at 60 rpm. The drying speed is a measure of the time (seconds) after application of the aqueous nail polish composition on a fingernail until complete drying. Gloss is measured using a BYK (BYK) garner gloss meter.

In comparative example 1, a Gloss value of 74 to 78 Gloss units (Gloss units) was shown, and a drying speed of about 7 minutes to 8 minutes and a viscosity of 2500cps to 4000cps were measured. This is similar to the physical properties of existing aqueous nail sticker formulations.

In comparative examples 2 and 3, in which stevioside was used alone, the drying rate was measured to be about 10 minutes, there was a problem in that the drying rate was increased compared to the existing dosage forms.

In comparative examples 4 and 5 using maltodextrin alone, there was a problem that the gloss was lower than that of the existing dosage form.

Examples 1 to 9 preparation of gloss agent composition for aqueous nail enamel

The ingredients described in the following table 3 were weighed out in a beaker for purified water (80 to 90 ℃) first, and then stirred at 100rpm using a dispersant (disper), and mixed uniformly for 3 minutes after maltodextrin and stevioside were sequentially added. At this time, the weight ratio of maltodextrin to stevioside was 1:1. Then, a thickener was sprayed and dropped, and stirring was performed while gradually increasing the rpm at 200 to 300rpm as the viscosity increased, and the mixture was uniformly mixed for 5 minutes. Thereafter, after simethicone and a preservative were sequentially added, the gloss agent composition was manufactured by continuously using a dispersant and uniformly mixing for 5 minutes. Table 3 below shows the specific components and contents of the aqueous nail polish composition according to examples 1 to 9. As a result, in the case of examples 1 to 4, light yellow transparent gel-like compositions were obtained. In the case of examples 5 to 9, yellowish turbid, gel-like compositions were obtained.

[ Table 3]

Production examples 1 to 9 production of aqueous nail polish composition

An aqueous nail polish composition was manufactured in the same manner as in comparative examples except that examples 1 to 9 were used as the gloss agent in table 2 instead of comparative examples 1 to 5. Toning was performed using 96 wt% of the manufactured aqueous nail polish composition and 4 wt% of the color.

Examples 10 to 17 manufacture of gloss compositions for aqueous nail polishes

Gloss agent compositions were manufactured in the same manner as in examples 1 to 9, except that the weight ratio of maltodextrin to stevioside was set to 4:1, 3:1, 2:1, 1.5:1, 1:1.5, 1:2, 1:3, and 1: 4. Table 4 below shows the specific ingredients and contents of the aqueous nail polish compositions according to examples 10 to 17. As a result, in the case of examples 10 to 17, the same pale yellow gel-like compositions as in examples 1 to 9 were obtained.

[ Table 4]

Preparation examples 10 to 17 preparation of aqueous nail enamel composition

Aqueous nail polish compositions were manufactured in the same manner as in the comparative examples, except that the examples 10 to 17 were used as the gloss agents in the table 2 instead of the comparative examples 1 to 5. Toning was performed using 96 wt% of the manufactured aqueous nail polish composition and 4 wt% of the color.

Test example 2 evaluation of gloss, drying speed, and viscosity according to the amount of polysaccharide

For the aqueous nail polish compositions according to the manufacturing examples 1 to 9, tests for evaluating gloss, drying speed, and viscosity were performed. In the case of the aqueous nail enamel, it is judged that the higher the gloss, the lower the drying speed, i.e., excellent physical properties, and the standard viscosity is 2000cps to 3500 cps.

As shown in fig. 1 to 3, the aqueous nail polish compositions of manufacturing examples 1 to 9 exhibited gloss levels of 80 to 90 gloss units, measured at a drying speed of about 5 minutes to 8 minutes, and viscosities of 2000cps to 4000 cps. In particular, in manufacturing example 7 using the gloss agent of example 7 including maltodextrin and stevioside in an amount of 40 wt%, the gloss was excellent, the drying speed was low, and the viscosity was within an appropriate range, and the physical properties were most excellent.

Test example 3 evaluation of gloss, drying speed, and viscosity according to the weight ratio of polysaccharides

For the aqueous nail polish compositions according to the manufacturing examples 10 to 17, tests for evaluating gloss, drying speed, and viscosity were performed. The test method was the same as in test example 2.

As shown in fig. 4 to 6, manufacturing examples 10 to 17 using maltodextrin and stevioside at various weight ratios showed a gloss of about 85 gloss units, and measured drying speeds of 5 minutes to 8 minutes and viscosities of 2000cps to 3500 cps. Thus, the gloss enhancement effect was excellent and the drying speed and viscosity were found to be suitable for use as a water-based nail polish.
