Description

[0001] The present invention relates to a cream modeling mask pack for a cosmetic composition,

The present invention relates to a cream modeling mask pack cosmetic composition having excellent moisture retention.

The pack cosmetics are divided into a wash-off type which is washed out after use and a peel-off type which is peeled off. Generally, the wash-off type is a creamy type, which is applied to the skin and left to rinse with warm water. The peel-off type base material is a jelly or paste type, which is applied to the skin and dried to form a film and then peeled by hand (Korean Patent No. 10-1207556).

As an example of the peel-off type, when a powder containing an alkali metal salt and a metal salt of a bivalent or higher metal is mixed with water, gelation occurs evenly as the powders are not uniformly mixed and precipitated or precipitated due to the low viscosity of water Or the surface of the pack becomes coarse after solidification, thereby causing irritation to the skin.

In order to solve the above problem, the present inventor intends to provide a composition for a modeling pack which can be rapidly mixed, uniformly dispersed and mixed without powdering or precipitating with each other, and not easily flowing down when skin is applied.

[Relation 1]

_{1.0 ≤ W A / W B ≤} 10

(In the above relational expression 1, W _A is the weight (g) of the algin and W _B is the weight (g) of the acrylic thickener.

The cream modeling mask pack cosmetic composition according to the present invention has an advantage of being able to mix easily and quickly and to pack in the form of a creamy one-pack and two powder-packed two-packs, Compared to conventional modeling mask packs that use only water, it can give long lasting feeling to the skin.

Further, it is also possible to use one agent comprising an algin, an acrylic thickener and a polyol; And a binder containing a monosaccharide, a metal salt containing two or more metal cations, a filler and a gelation rate controlling agent, whereby the two-agent powder is uniformly dispersed and evenly dispersed in the liquid phase without aggregation or precipitation Thus, the surface of the pack can be smoothly and smoothly wrinkled without gelation, thereby preventing wrinkles of the skin and imparting elasticity to the skin.

In addition, when used on skin, it is easy to remove keratin, has excellent moisturizing effect, and has a better effect of soothing the skin because the temperature in the pack is lower than body temperature.

In particular, it is possible to have an excellent gradual effect by mixing the algin and the acrylic thickener to satisfy the relationship (1).

Hereinafter, the cream modeling mask pack cosmetic composition according to the present invention and the cream modeling mask pack prepared therefrom will be described in detail.

Here, unless otherwise defined, technical terms and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present invention belongs. In the following description, the gist of the present invention is unnecessarily blurred And a description of the known function and configuration will be omitted.

The modeling mask pack refers to a pack which is manufactured so that it can be easily detached from the skin by converting into a solid having elasticity as the time elapses through the gelation reaction of the algin and calcium ions, and is also referred to as a rubber pack.

In general, the modeling mask pack has a disadvantage in that when the powder containing the algin and the calcium salt is used in water, the water easily evaporates and the skin is easily dried.

On the other hand, according to the present invention, a cream containing an excessive amount of a polyhydric alcohol in place of water as a liquid agent can provide a long-lasting moisturizing effect to the skin as compared with a modeling mask pack using only water. In addition, the cream modeling mask pack has the advantage of providing various functions such as whitening and wrinkle improvement, including moisturizing to the skin, so that it is possible to manufacture a product group that meets different consumers' preferences.

In addition, in the case of conventional modeling mask packs, inorganic powders such as kaolin to diatomaceous earth have been used in large quantities as excipients for the stability of the powder itself during circulation. However, instead of reducing the content of inorganic powders, this product can provide superior moisture resistance compared to conventional modeling masks by using saccharides having a large amount of -OH functional groups.

Specifically, the present invention relates to a composition comprising an algin, an acrylic thickener, and a polyol; The present invention relates to a cream modeling mask pack cosmetic composition, which comprises a salt containing a metal cation, a metal salt containing a divalent or higher metal cation, a filler and a gelation rate regulator, wherein the algin and the acrylic thickener satisfy the following relational expression .

[Relation 1]

_{1.0 ≤ W A / W B ≤} 10

(In the above relational expression 1, W _A is the weight (g) of the algin and W _B is the weight (g) of the acrylic thickener.

The cream modeling mask pack cosmetic composition according to an embodiment of the present invention has the advantage of being able to mix easily and quickly when using the cream form cosmetic composition and the powder form cosmetic composition, Compared to conventional modeling mask packs that use only water, it can give a long lasting feeling to the skin.

In addition, by having the above-described composition of the first and second components, the two-component powder can be uniformly dispersed and mixed evenly with the one component which is liquid without being clumped or precipitated, whereby the surface of the pack is smoothly solidified It is possible to prevent the wrinkles of the skin and give the skin elasticity.

In addition, when used on skin, it is easy to remove keratin, has excellent moisturizing effect, and has an effect of soothing the skin because the temperature in the pack is lower than body temperature.

In particular, it is possible to have an excellent gradual effect by mixing the algin and the acrylic thickener to satisfy the relationship (1). Better than, the weight ratio of the alginate with an acrylic thickener may be to satisfy _{1.5 ≤ W A / W B ≤} 6.0. By satisfying the above range, not only does it have an excellent gradual effect, but also the viscosity can be controlled appropriately, so that the composition can have excellent applicability without falling down and aggregation during application of the skin. In addition, the powder dispersibility is improved, and the two components can be uniformly dispersed and mixed within 10 seconds upon mixing with the binder.

Hereinafter, each component will be described in detail in the cream modeling mask pack cosmetic composition according to an example of the present invention.

The first agent may include an alginate, an acrylic thickener, and a polyol, as described above. More specifically, the first agent may be an aqueous solution containing an alginate, an acrylic thickener, and a polyol.

The content of each constituent material may be varied depending on the characteristics of the desired modeling pack. Specifically, for example, 0.1 to 10% by weight of alginic acid, 0.05 to 20% by weight of acrylic incremental agent and 0.1 to 10% by weight of polyol 1 By weight to 30% by weight, and the remaining unincorporated ingredient may be water. More preferably from 0.5 to 5% by weight of algin, from 0.1 to 10% by weight of acrylic builder and from 2 to 15% by weight of polyol, more preferably from 1 to 3% by weight of algin, from 0.5 to 3% by weight of acrylic builder, And 3 to 10% by weight of polyol. Within this range, the effect of the gradual increase is excellent, and it is possible to have an appropriate viscosity. At this time, it is a matter of course that the weight ratio of the algin and the acrylic thickener must satisfy the above-mentioned relational expression 1.

More specifically, the first agent according to an embodiment of the present invention may have a viscosity of 10,000 to 50,000 cps, more preferably 25,000 to 45,000 cps. As mentioned in the above-mentioned viscosity range, when mixed with the powder form 2, 2 can be dispersed evenly without being settled. When the powder is applied to the skin, it is closely adhered to the skin, Can be greatly improved, and it can be used very easily because it does not flow well. On the other hand, when the viscosity of the first agent is too low, the sedimentation of the powder proceeds rapidly and dispersion stability can not be secured, and a dropping phenomenon may occur when applying the skin. On the other hand, when the viscosity of the one agent is too high, mixing with the two agent powder may not be easy, and it may be difficult to apply the skin because of the agglomeration phenomenon. Therefore, the viscosity of one agent having a cream phase plays a very important role in dispersing various kinds of powders and ensuring the degree of appearance.

In one embodiment of the present invention, when an algin is mixed with a binary agent, the algin is reacted with a divalent or higher metal cation provided by a metal salt containing two or more metal cations of two or more, A mixed solution can be obtained, and the one-component and two-component can be rapidly mixed and evenly dispersed and mixed. On the other hand, when the algin is not used, the surface of the mixture may be rough and the surface of the mixture may be scattered when mixed with the two agents.

Specifically, for example, the alginate may be alginic acid, alginate, or a mixture thereof. The alginate may be any one or more selected from sodium alginate (algin), potassium alginate, ammonium alginate, triethanolamine alginate, But it is preferable to use them selectively by dissolving them well in water.

In one embodiment of the present invention, the acrylic thickener is used to improve the gradual effect, and includes a homopolymer containing a repeating unit represented by the following formula (2), a repeating unit represented by the following formula (1) ≪ / RTI > In this case, the repeating unit represented by the following formula (1) and the repeating unit represented by the following formula (2) may be randomly bonded, and the molar ratio of the repeating unit of the formula (1) to the repeating unit of the formula (2) may be 1: 9 to 9: But is not limited thereto.

The nonionic aliphatic surfactant may be an alkylene oxide adduct type, an alkylene oxide adduct-polyhydric alcohol type, or a mixture thereof. More specifically, in one non-limiting embodiment, the alkylene oxide adduct type is any one or two or more selected from Laureth-7, Laureth-9 and Laureth-23, and the alkylene oxide adduct- The polyhydric alcohol type may be any one or two or more selected from polysorbate 20, polysorbate 40, polysorbate 60 and polysorbate 80, but is not limited thereto. The branched aliphatic hydrocarbon may be any one or two or more selected from isohexadecane, isooctadecane, etc., isoalkane having 14 to 18 carbon atoms, and isoparaffin having 13 to 14 carbon atoms, but is not limited thereto.

The amount of the nonionic aliphatic surfactant and the branched aliphatic hydrocarbon to be added may be 0.01 to 10% by weight, more preferably 0.1 to 5% by weight, of the total weight of the composition, The content thereof can be adjusted as needed within a range not exceeding the above range.

In addition, the first agent according to an embodiment of the present invention may further include a functional powder. The functional powder may be selected according to the intended purpose, and as a specific example, pearl powder, pigment and the like may be used. The pulp or pigment is used for improving the visual effect, and is not particularly limited as long as it is commonly used in the art.

Specifically, for example, the pulp may be any one or more selected from titanium coated mica, bismuth oxychloride coated mica, iron oxide coated titanium mica and chromium oxide coated titanium mica, but is not limited thereto.

The average particle size of the functional powder is not particularly limited, but it is preferable to use one having a size such that the dispersion is not well-dispersed and well dispersed in one agent. In one embodiment, the average particle size of the functional powder is 1 nm to 1 Mm, more preferably from 1 to 500 mu m, and even more preferably from 5 to 150 mu m. The visual effect is excellent in the above-mentioned range and can be easily dispersed in one component.

The amount of the functional powder to be added may be freely added within a range that does not impair the physical properties of the cream modeling mask pack cosmetic composition, but may be preferably 0.1 to 5% by weight, more preferably 0.5 to 5% by weight, 3% by weight. If the addition amount of the functional powder is too small, it is difficult to secure the desired physical properties. If the addition amount of the functional powder is too large, the surface of the pack may become rough after gelation.

In addition, the one agent according to one embodiment of the present invention can be added to the cream modeling mask pack cosmetic composition to the extent that the physical properties of the cream modeling mask pack cosmetic composition are not impaired by the surfactant, antioxidant, stabilizer, pH adjusting agent, preservative, Perfumes, and the like.

As described above, the second agent may include a monosaccharide, a metal salt containing two or more metal cations, a filler, and a gelation rate modifier. More specifically, the second agent may be a monosaccharide, A metal salt, a filler, and a gelation rate controlling agent.

The content of each constituent material may be varied depending on the characteristics of the desired cream modeling mask pack cosmetic composition. Specifically, for example, in the total weight of the two agents, 60 to 95% by weight monosaccharide, 2 or more metal cations 1 to 25% by weight of a metal salt, 0.5 to 15% by weight of a filler, and 0.1 to 10% by weight of a gelling rate modifier. More preferably from 70 to 90% by weight of monosaccharides, from 2 to 20% by weight of a metal salt containing at least two metal cations, from 1 to 10% by weight of a filler and from 0.5 to 5% by weight of a gelling rate modifier, From 5 to 15% by weight of a metal salt containing at least two metal cations, from 3 to 8% by weight of a filler, and from 1 to 3% by weight of a gelling rate modifier.

In one example of the present invention, the monosaccharide is added to improve the moisturizing effect and the skin protection effect, and is not particularly limited as long as it is commonly used in the art. Specifically, it may be, for example, any one or more selected from glucose, mannose, galactose, ribose, xylose and arabinose, but is not limited thereto. Thus, by using a monosaccharide having a large amount of OH functional groups, it is possible to provide an excellent moisture resistance as compared with the conventional modeling mask.

In one embodiment of the present invention, a metal salt containing two or more metal cations is added in order to allow the mixture to gel by reacting with an algin by providing a metal cation when mixed with the one agent, And is not particularly limited so long as it is not harmful. For example, the divalent or higher metal cation may be any one or two or more selected from calcium ion, magnesium ion, and aluminum ion. More specifically, for example, metal salts containing two or more metal cations can be selected from the group consisting of calcium chloride, calcium hydroxide, calcium carbonate, calcium sulfate, calcium phosphate, calcium nitrate, calcium acetate, calcium oxide, calcium stearate, calcium silicate, Calcium ascorbate, calcium lauryl sulfate, magnesium chloride, magnesium hydroxide, magnesium carbonate, magnesium sulfate, magnesium phosphate, magnesium nitrate, magnesium acetate, magnesium oxide, magnesium oxide, calcium phosphate, Magnesium stearate, magnesium stearate, magnesium stearate, stearate, magnesium silicate, magnesium thioglycolate, magnesium pantothenate, magnesium myristate, magnesium lanolate, magnesium ascorbyl phosphate, magnesium lauryl sulfate, aluminum distearate, aluminum monostearate, Aluminum chloride, aluminum chlorohydrate, and aluminum hydroxychloride, and the like.

In one embodiment of the present invention, the filler is not particularly limited as long as it is commonly used in the art. Specific examples thereof include diatomaceous earth, silica, kaolin, magnesium carbonate, talc, titanium dioxide, zinc oxide and crystalline cellulose And the like. It is preferable to use diatomaceous earth. Diatomaceous earth is a particle having a high porosity and has a property of absorbing liquid. Therefore, when it is applied to the skin after mixing the aqueous solutions 1 and 2, the water does not flow to the skin This helps prevent dryness of the pack and provides moisture to the skin. Also, diatomaceous earth can supply nutrients to the skin because it contains many minerals.

In one example of the present invention, the gelling rate controlling agent provides a time for sufficiently mixing the first agent and the second agent by controlling the rate of gelation, and allows gelation to occur rapidly after application of the skin, It can be used without particular limitation. Specifically, for example, an alkali metal salt of phosphoric acid can be used. As a non-limiting example, sodium metaphosphate, sodium orthophosphate, sodium pyrophosphate, potassium metaphosphate, potassium orthophosphate, sodium pyrophosphate and sodium hexametaphosphate And the like.

In addition, the agent according to an example of the present invention may further include a functional peptide. The functional peptide is for imparting effects such as skin whitening, skin regeneration, skin aging prevention and wrinkle prevention, and includes, for example, dipeptide, tripeptide, tetrapeptide, pentapeptide, hexapeptide, oligopeptide, nicotinoyldi But are not limited to, any one or two or more selected from peptide-2, palmitoylpentapeptide-4, copper tripentamide, acetylhexapeptide-8, collagen peptide and palmitoyl oligopeptide.

In addition, the second agent according to an embodiment of the present invention can be used as a surfactant, an antioxidant, a stabilizer, a pH adjuster, a preservative, a disinfectant, or a perfume, etc. commonly used in the art within a range that does not impair the physical properties of the composition for a modeling pack And may further include powder.

The present invention also provides a cream modeling mask pack made from the cream modeling mask pack cosmetic composition described above.

In detail, the cream modeling mask pack according to the present invention comprises one agent comprising an algin, an acrylic thickener and a polyol; And a binder comprising a monosaccharide, a metal salt containing two or more metal cations, a filler and a gelation rate regulator, wherein the algin and the acrylic thickener may satisfy the following relational expression 1 .

[Relation 1]

_{1.0 ≤ W A / W B ≤} 10

(In the above relational expression 1, W _A is the weight (g) of the algin and W _B is the weight (g) of the acrylic thickener.

Thus, by using a cream containing an excessive amount of polyhydric alcohols instead of water as the liquid agent, a moisturizing feeling can be provided for a long time on the skin as compared with a modeling mask pack using only water. In addition, since the first and second agents have the above compositions and the two-agent powder is uniformly dispersed and evenly mixed with the one agent in liquid phase without aggregation or precipitation, the surface of the pack after gelling is smoothly and smoothly wrinkled, , And can have an effect of imparting elasticity to the skin. In addition, when used on skin, it is easy to remove keratin, has excellent moisturizing effect, and has a better effect of soothing the skin because the temperature in the pack is lower than body temperature.

At this time, the above-mentioned algin, acrylic thickener, polyol, monosaccharide, metal salt containing two or more metal cations, filler, and gelation rate regulator are the same as those described above, and a duplicate explanation will be omitted.

In one embodiment of the present invention, the cream modeling mask pack is prepared by mixing a metal salt containing an alginate and a metal cation having two or more valences by the mixing of a first agent and a second agent, And may have an interpenetrating polymer network (IPN) by a gelation reaction of the alginate and a metal salt containing two or more metal cations. As a result, it is easily peeled off from the skin and can have a high moisture retention.

Hereinafter, the cream modeling mask pack cosmetic composition according to the present invention will be described in more detail by way of examples. It should be understood, however, that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the invention.

Unless otherwise defined, all technical and scientific terms have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. In addition, the unit of the additives not specifically described in the specification may be% by weight.

[Evaluation of moisture retention]

The moisture retention of the mask pack composition of Example 1 and Comparative Example 1 was measured in order to confirm the change of the moisture-holding capacity between the products over time. The results are shown in Table 3 below.

In Example 1, a mask pack was prepared by mixing 1 g of 100 g and 20 g of 2 g. In Comparative Example 1, 25 g of the mask pack composition was mixed with 50 g of water to prepare a mask pack.

In addition, the rate of increase in the moisture resistance of the mask pack cosmetic composition of Example 1 against Comparative Example 1 was calculated by the following equation.

Moisture power increase rate (%) = (A-B) / A x 100

In the above formula, A is the water retention of Comparative Example 1, and B is the water retention of Example 1. [

At this time, the water retention was evaluated in 20 subjects after the forearm was washed with water and then stabilized under constant temperature and humidity (20 to 24 ° C, 40 to 60% RH) for 30 minutes. The test site (forearm) was the frontal oyster lateral part 5 ㎝ from the wrists of the left and right arms of the subjects. Five 5 - cm square And moisture retention was measured.

The moisture content was measured by a Corneometer (CM 825, Courage & Khazaka, Germany). After 5 hours of application, 1 hour after application, 3 hours after application, 6 hours after application and 24 hours after application The moisture retention of each subject was measured, and the average value thereof is shown in Table 3 below.

Moisture retention (A.U., arbitrary unit) Moisture power increase rate
(%) Product unused A B Before Wear 36.64 36.20 36.75 - 1 hour after wearing 36.55 39.26 45.63 16.23 3 hours after wearing 36.64 37.55 43.21 15.07 6 hours after wearing 36.64 36.85 41.81 13.46 After 24 hours of wear 36.65 36.50 40.81 11.81

As shown in Table 3, the moisture retention at the time of non-use of the product was maintained at a constant level over time.

On the other hand, Example 1 showed the highest moisture retention of 45.63 A.U. after 1 hour of wearing, and a high moisture increasing rate of 16.23% higher than Comparative Example 1. Even after 24 hours of wearing, Example 1 also exhibited a moisture retention of 40 A.U. And 11.81% higher than Comparative Example 1, respectively.

On the other hand, Comparative Example 1 had low moisture retention compared to Example 1, and showed moisture retention similar to that of the product not used after about 6 hours of wearing, indicating that there is almost no persistence of moisture retention.

From this, it was confirmed that the cream modeling mask pack cosmetic composition according to the present invention is not only capable of providing excellent moisture resistance to the skin as compared with a powder-type mask pack which is generally used, but also maintaining its sustaining power effectively.

[Example 2]

A cream modeling mask pack cosmetic composition was prepared in the same manner as in Example 1 except that 3% by weight of an acrylic thickener was added so that the weight ratio of sodium alginate and acrylic thickener (W _A / W _B ) was 1.

[Example 3]

In Example 1 but preparing the same modeling cream mask pack cosmetic composition and, for the acrylic thickener in a weight ratio of sodium alginate and an acrylic thickener (W _A / W _B) to be 5 was added 0.6% by weight.

[Example 4]

A cream modeling mask pack cosmetic composition was prepared in the same manner as in Example 1 except that 0.3 weight% of an acrylic thickener was added so that the weight ratio of sodium alginate and acrylic thickener (W _A / W _B ) was 10.

[Comparative Example 2]

A cream modeling mask pack cosmetic composition was prepared in the same manner as in Example 1 except that 5% by weight of an acrylic thickener was added so that the weight ratio of sodium alginate and acrylic thickener (W _A / W _B ) was 0.6.

[Comparative Example 3]

A cream modeling mask pack cosmetic composition was prepared in the same manner as in Example 1 except that 0.25% by weight of an acrylic thickener was added so that the weight ratio of sodium alginate to acrylic thickener (W _A / W _B ) was 12.

[Property evaluation]

In order to evaluate the physical properties of the cream modeling mask pack cosmetic compositions of Examples 1 to 4 and Comparative Examples 2 to 3, the viscosity of one agent was measured and the results are shown in Table 4. At this time, the viscosity can be measured by a viscosity measuring instrument. In the present specification, the viscosity is BROOKFIELD RVDV2T, and the viscosity of the spindle NO. 06, and a speed of 5 RPM.

W _A  (weight%) W _B  (weight%) W _A / W _B Viscosity (cps) Example 1 3.0 1.5 2 32,000 Example 2 3.0 3.0 One 67,000 Example 3 3.0 0.6 5 12,800 Example 4 3.0 0.3 10 10,000 Comparative Example 2 3.0 5 0.6 130,000 Comparative Example 3 3.0 0.25 12 8,000

As a result, in the mask packs according to Examples 1 to 4, the first and second agents were uniformly dispersed and mixed uniformly, and the coating was easy to apply to the face since the wetting and aggregation phenomenon was not so severe. After the gelling reaction, .

Particularly, the mask packs of Examples 1 and 3 were uniformly mixed with the first agent and the second agent within 10 seconds, and showed excellent physical properties because there was no spilling and aggregation.

On the other hand, in Comparative Example 2, the viscosity was too high to mix the two agents uniformly in one agent, and the aggregation phenomenon was so severe that the application of the agent to the face was difficult. The viscosity of Comparative Example 3 was too low to cause the mixture of the first and second agents to flow down to the floor before being fixed to the face.
