Description

Dry sheet pack with superior moisturizing effect and preparation method thereof

The present invention relates to a dry sheet-type cosmetic pack having excellent moisturizing power, and more specifically, by using it on a hand with water instead of a towel, a dry sheet-shaped cosmetic pack capable of removing moisture on the hand and providing excellent moisturizing power to the hand. It relates to a manufacturing method.

The skin is the most externally located organ of the body, protecting the internal organs from external stimuli and playing an important role in maintaining life. Because the skin is exposed to the outside of the body, it is receiving a great deal of cosmetic attention through human history. Especially in the case of women, due to the instinctive aesthetic desire, efforts have been made to steadily clean the skin from the past, and recently, men who are interested in skin care are increasing according to this trend.

Usually, skin care is done by applying skin and lotion to the skin every day after washing or showering. In particular, in situations where higher moisturizing or nutrition is required, a mask pack in which a cosmetic composition is impregnated with a substrate such as a nonwoven fabric is sometimes used. However, since these mask packs are generally manufactured for faces, it is difficult to apply them to other body parts in the form or nutritional components of the mask pack.

Thus, the moisturizing and whitening effect on the skin is repeated by repeating the operation of dipping and removing the hand in paraffin melted at 55°C to moisturize the hand among other body parts except the face, and after waiting for a certain period of time, removing the hardened paraffin. Paraffin therapy has also been used.

However, paraffin therapy is a risk of burns, and some patients with arthritis or diabetes have side effects that worsen the disease. In addition, there is a problem that it takes a long time because you have to visit a beauty company that specializes in paraffin therapy and undergo a procedure.In the case of direct treatment, the cost of purchasing a machine and paraffin in the initial stage is small, so it is simple and cheap. It was required to develop a cosmetic pack for the hand that can be used easily.

Accordingly, as in the registered patent No. 1846384 (2018.04.02 registration notice), it has a glove shape with an opening formed on one side, and includes a supporting layer containing a cosmetic liquid inside the long job and a non-permeable outer layer on the outside of the glove, worn on the hand And after a certain period of time, a cosmetic pack for the hand has been developed to provide moisturizing power to the hand by desorption. However, such a glove-shaped cosmetic pack has a high manufacturing cost, is expensive, and has a non-permeable outer layer on the outside of the glove, causing sweat in the hand and feeling of heat in the hand while absorbing active ingredients and reducing wear. There was a problem.

If such a glove-type hand pack is not used regularly, there is a problem that the cosmetic effect is not maintained for a long period of time, but the glove-type hand pack is expensive, and it is difficult to use regularly because it requires expensive time and effort to use it. There is a need for the development of a cosmetic pack that can moisturize the hand more inexpensively and conveniently.

Registered Patent No. 1846384 (2018.04.02 registration notice)

In the present invention, in order to provide a cosmetic pack that can be conveniently used instead of a glove-type hand cosmetic pack, a cosmetic sheet composition comprising a surfactant having a specific HLB (Hydrophile-lipophile Balance) value in a specific ratio is impregnated or coated on a substrate. Provided, it is intended to provide a dry sheet type cosmetic pack and a method of manufacturing the same, which can provide moisturizing power to the skin by using instead of a towel when wiping hands with water.

The additive may include at least one or more additives selected from the group consisting of emulsifying stabilizers, preservatives, conditioning agents, and pH adjusting agents.

The dry sheet-type cosmetic pack of the present invention, unlike a conventional glove-type hand cosmetic pack that requires a certain amount of time to wear a glove-type hand cosmetic pack to provide moisturizing power to the hand, removes water from the hand after wiping the hand in everyday life To be used instead of a towel, you can easily provide moisturizing power to your hands.

Before describing in detail through preferred embodiments of the present invention, terms or words used in the present specification and claims should not be interpreted as being limited to conventional or dictionary meanings, and meanings consistent with the technical spirit of the present invention. And should be interpreted as a concept.

Throughout this specification, when a part “includes” a certain component, it means that the component may further include other components, not to exclude other components, unless specifically stated otherwise.

Throughout this specification, "%" used to indicate the concentration of a specific substance, unless otherwise specified, solids/solids (weight/weight)%, solids/liquids (weight/volume)%, and liquid /Liquid means (volume/volume)%.

Hereinafter, the dry sheet-like cosmetic pack of the present invention and a method of manufacturing the same will be described in more detail.

First, the dry sheet-shaped cosmetic pack of the present invention is a cosmetic pack composition comprising 5 to 17% by weight of a moisturizing agent, 0.8 to 9% by weight of a surfactant, 0.01 to 0.1% by weight of a polymer thickener, 0.5 to 3% by weight of an additive, and the remaining amount of purified water and the cosmetic pack It includes a substrate on which the composition is impregnated or coated.

The dry sheet-like cosmetic pack of the present invention may have a moisture content of 1 to 10% by weight, and more preferably 2 to 7% by weight. In this case, the moisture content of the dry sheet-like cosmetic pack does not occur due to bacterial or bacterial growth, the cosmetic pack composition is broken and can be adhered to the substrate without the phenomenon of peeling off the substrate.

The dry sheet-like cosmetic pack of the present invention is used instead of a towel on wet skin, for example, wet hands, so that the dry cosmetic pack composition and hand moisture are mixed to remove moisture from the hands while providing moisture. It works. The moisturizing power of the dry sheet type cosmetic pack appears when the dry sheet type cosmetic pack is applied to wet skin, and does not appear when applied to dry skin.

In general, the description of moisture in the hand includes both moisture contained in the skin and moisture attached to the outside of the skin, but in the present specification, substrates such as moisture in the hand and moisture on the hand are included in the skin. It means only excess moisture attached to the outside of the skin, not moisture.

In addition, in the present specification, the descriptions of the skin in a wet state, a wet state and a wet state are irrespective of the amount of moisture contained in the skin, and the hand is stained with water, such as after washing hands with water. It means the state.

Meanwhile, the cosmetic pack composition that can be used instead of a towel to remove water from the body such as a hand and provide moisturizing power at the same time includes 5 to 17% by weight of a moisturizer, 0.8 to 9% by weight of a surfactant, and 0.01 to 0.1% by weight of a polymer thickener. , 0.5 to 3% by weight of additives and the remaining amount of purified water.

The moisturizer serves to maintain moisture and smooth skin by forming a film to supply moisture to the skin and prevent evaporation of the supplied moisture, and the cosmetic pack composition of the present invention may be included at 5 to 17% by weight.

When the moisturizing agent is contained in less than 5% by weight, the effect of improving the moisturizing power of the skin is minimal, and when it exceeds 17% by weight, the time required to dry the cosmetic pack composition is increased after impregnating or coating the cosmetic pack composition on the substrate, When used on wet skin, it is difficult to mix with moisture on the skin, and there is a problem in that the time required to dry the skin again after using a dry sheet type cosmetic pack is increased.

Moisturizing agents include glycerin, propylene glycol, butylene glycol, dimethicone, cyclomethicone, polydimethylsiloxane, methylphenylpolysiloxane, triethylhexanoin, cetylethylhexanoate, cetyloctanoate, cetylisooctanoate, and pentaeryis. Lithyltetraethylhexanoate, caprylic/capric triglyceride, isopropylpalmitate, isopropylmyristate, tocopherol acetate, dicapryliccarbonate, tripropylene glycol alkyl ether (C1-C4) and hydrogenated poly( C6-14 olefin) may be used one or more moisturizers selected from the group consisting of.

Preferably, a mixture of glycerin, dimethicone, pentaerythryltetraethylhexanoate, hydrogenated poly(C6-14 olefin) and caprylic/capric triglyceride can be used, and such a mixture is used as a moisturizer. By minimizing the amount of moisturizer lost in the drying step of the manufacturing method of the dry sheet-shaped cosmetic pack to be described later it can secure the moisturizing power of the dry sheet-shaped cosmetic pack.

Moisturizers to exhibit these effects are glycerin 11-40% by weight, dimethicone 4-14% by weight, pentaerythryltetraethylhexanoate 8-20% by weight, hydrogenated poly(C6-C14 olefin) 10-43 Weight percent and caprylic/capric triglyceride 10-43 weight percent.

More preferably, a mixture further containing tripropylene glycol alkyl ether (C1-C4) in the aforementioned moisturizer mixture may be used, and in this case, moisture of the skin with moisture due to interaction with a surfactant to be described later. It has the advantage that the mixing of the cosmetic pack composition and the cosmetic pack composition is more effectively caused and the moisture on the skin is quickly removed and the cosmetic pack composition is more effectively applied and absorbed on the skin.

When the tripropylene glycol alkyl ether (C1-C14) is further included, the mixture may further contain 5 to 16 wt% of the tripropylene glycol alkyl ether (C1-C14) based on 100% by weight of the total moisturizer. have.

If the content of tripropylene glycol alkyl ether (C1-C14) is less than 5% by weight based on the total moisturizer, no effect is exhibited, and when it exceeds 16% by weight, absorption of the cosmetic pack composition applied to the skin is delayed. Therefore, it is preferable to be included within the above-mentioned weight range.

The surfactant functions to mix a hydrophilic component and a hydrophobic component included in the cosmetic pack composition to form a stable phase. In the present invention, as well as a role as an emulsifier, when the dry sheet-like cosmetic pack is applied to wet skin, the water on the skin is pulled toward the dry sheet-shaped cosmetic pack to quickly remove moisture from the skin, and the part of the moisture is mixed with the cosmetic pack composition. It also performs functions. The latter function is more effective when it includes tripropylene glycol alkyl ether (C1-C14) as a moisturizer as described above.

The surfactant may be included in 0.8 to 9% by weight, and when it is included in less than 0.8% by weight, it is difficult to perform the function as the surfactant described above, and when it is included in excess of 9% by weight, the phase stability is lowered. It is preferable to be included within the above-mentioned range.

Such surfactants include 52 to 66% by weight of a hydrophilic surfactant having a HLB (Hydrophile-lipophile Balance) value of 13 or more and a hydrophobic surfactant having a HLB value of 5 or less, which is a value obtained by quantifying the ratio of the hydrophilic group and the hydrophobic group included in the surfactant. It can be a mixture of 48% by weight.

At this time, the HLB value of the hydrophilic surfactant is limited to 13 or more, because when the HLB value is 13 or more, the effect of pulling water on the skin toward the dry sheet-like cosmetic pack appears, and the HLB value of the hydrophobic surfactant is 5 or less. The limit is to effectively emulsify the oil component.

When the hydrophilic surfactant having an HLB value of 13 or more is contained in an amount of less than 52% by weight, the time taken to pull the water on the skin toward the dry sheet-like cosmetic pack increases, making it difficult to use substantially. On the other hand, when it exceeds 66% by weight, the moisturizing power is lowered, and when using a dry sheet type cosmetic pack, there is a problem that a time taken to mix a part of the moisture and the cosmetic pack composition increases. In addition, since the time required for emulsification is increased when manufacturing the cosmetic pack composition, the overall process time is increased, so it is preferable to be included within the above-described composition range.

As a hydrophilic surfactant with an HLB value of 13 or higher, polysorbate 20, polysorbate 60, polysorbate 80, PEG-8 laurate, PEG-20 methylglucose sesquistearate, PEG-100 stearate, PEG-80 sorbate At least one selected from the group consisting of non-laurate, steareth-20, steareth-21, and steareth-100 may be used.

As a hydrophobic surfactant having an HLB value of 5 or less, at least one or more selected from the group consisting of glycol stearate, glyceryl stearate, sorbitan stearate, sorbitanolate, sorbitan trioleate and sorbitan sesquioleate Can be used.

At this time, preferably, a mixture of 4 to 23% by weight of PEG-100 stearate and 77 to 96% by weight of polysorbate 60 may be used as a hydrophilic surfactant, and 55 to 85% by weight of glyceryl stearate as a hydrophobic surfactant. And sorbitan sesquioleate 15 to 45% by weight of the mixture may be used.

The cosmetic pack composition contains 0.01 to 0.1% by weight of a polymer thickener relative to the total cosmetic pack composition. When the polymer thickener is contained in an amount of less than 0.01% by weight, the thickening effect is negligible, and when it exceeds 0.1% by weight, the time taken in the drying process significantly increases during the manufacturing process to be described later, and the dried dry sheet-like cosmetic pack is viscous. This is because separation is difficult.

Such polymer thickeners include polyacrylic acid, vinylpyrrolidone-acrylic acid copolymer, hydroxyethyl acrylate/sodium acryloyl dimethyl taurate copolymer, carbomer, acrylate/C10-30 alkyl acrylate cross polymer, alginic acid, One or more polymer thickeners selected from the group consisting of pectin and xanthan gum may be used, but carbomer is preferably used in terms of miscibility with other raw materials and ease of drying during the manufacturing process.

On the other hand, the cosmetic pack composition contains 0.5 to 3% by weight of additives relative to the total cosmetic pack composition. The additive is added to add an additional effect to the cosmetic pack composition, and any known material may be used as long as it does not impair the physical properties and effects of the aforementioned cosmetic pack composition and the dry sheet-like cosmetic pack.

Preferably, an emulsifying stabilizer, a preservative, a conditioning agent, and a pH adjusting agent may be included. In this case, 45 to 62% by weight of an emulsifying stabilizer, 22 to 41% by weight of a preservative, 3 to 15% by weight of a conditioning agent, pH in this case Adjuster 1 to 5% by weight may be included.

Emulsifier stabilizers are added for stabilization by preventing phase separation due to reaggregation of the emulsified components due to the surfactant, glyceryl stearate citrate, cetostearyl alcohol, potassium cetyl phosphate, cetyl alcohol, stearyl alcohol and three It may be at least one or more substances selected from the group consisting of thiaryl alcohol, but may preferably be cetearyl alcohol.

Preservatives are added to inhibit the growth of bacteria or bacteria, and to prevent rancidity of the cosmetic pack composition, selected from the group consisting of methylparaben, propylparaben, imidazolidinylurea, phenoxyethanol and 1,2-hexanediol Although at least one preservative may be used, it is preferable to use phenoxyethanol with less side effects on the human body such as skin irritation.

Conditioning agents are added to improve dry and damaged skin, reduce skin detachment, and restore skin flexibility, and various known conditioning agents that do not impair the physical properties of the dry sheet-like cosmetic pack of the present invention can be used, but preferably It is more preferable to use ethylhexylglycerin, which has both a conditioning effect and a preservative effect.

As the pH adjusting agent is added to improve the phase stability of the cosmetic pack composition by adjusting the pH of the cosmetic pack composition, an aqueous solution containing lithium hydroxide, sodium hydroxide or potassium hydroxide may be used. In particular, the use of 80 to 90% of potassium hydroxide can effectively act to alleviate the decrease in pH due to the emulsifying stabilizer cetearyl alcohol.

Meanwhile, the substrate on which the above-mentioned cosmetic pack composition is impregnated or coated may be a sheet-like fiber material, and preferably a non-woven fabric.

At this time, the thickness of the nonwoven fabric may be 0.5 mm or more, and when the thickness of the nonwoven fabric is 0.5 mm or less, when the dry sheet type cosmetic pack is used for wet skin, the nonwoven fabric may be easily broken by moisture transferred from the skin to the dry sheet type cosmetic pack. Because there is.

The nonwoven fabric is manufactured in a web shape using one or more selected from the group consisting of cotton, hemp, polyester and polypropylene, and it is preferable not to use those made of a material such as polyamide or rayon having high hydrophobicity.

When the non-woven fabric includes polyester or polypropylene, when using a non-woven fabric manufactured using a spunbond or melt-blown method of mixing these raw materials and a hydrophilic additive, the excess moisture remaining in the wet skin It can be removed more effectively. At this time, the hydrophilic additives that can be used include, for example, Techsurf ^® 15560, Unithox ^® 480, Unithox ^® 550, but are not limited thereto.

The dry sheet-like cosmetic pack of the present invention includes a cosmetic pack composition having the above-described ingredient ratio, so that it does not impart a moisturizing effect to dry skin, and is applied to wet and wet skin to remove moisture on the skin. , Some moisture is easily mixed with the cosmetic pack composition to have a moisturizing effect on the skin.

Therefore, such a dry sheet-like cosmetic pack is used instead of a towel to remove moisture in the presence of moisture on the skin, so that excess moisture attached to the skin can be removed, and a quick, simple and effective moisturizing effect can be given to the skin. have.

The dry sheet-type cosmetic pack may be provided for a single use in which one dry sheet-type cosmetic pack is drawn into a pouch, or may be provided for multiple uses in which two or more dry sheet-type cosmetic packs are inserted. In the case of a multi-layer type, it may be provided in a package such as a tissue to be pulled out.

On the other hand, another embodiment of the present invention relates to a method of manufacturing a dry sheet-like cosmetic pack, moisturizer 5 to 17% by weight, surfactant 0.8 to 9% by weight, polymer thickener 0.01 to 0.1% by weight, additives 0.5 to 3% by weight and residual amount Cosmetic pack composition manufacturing step of mixing the purified water of the temperature range of 60 ~ 90 ℃, immersing the substrate in a cosmetic pack composition having a temperature range of 70 ~ 80 ℃, immersion step of impregnating or coating the moisturizer composition on the substrate and the cosmetic pack And a drying step of drying the substrate on which the composition is impregnated or coated.

The raw materials used in the cosmetic pack composition manufacturing step are the same as described above, and thus will be omitted.

The cosmetic pack composition manufacturing step may be performed by mixing the above-described raw materials in a temperature range of 60 to 90°C. If the mixing temperature is less than the above range, there is a problem that sufficient mixing and emulsification of the raw material is not achieved, and if it exceeds the above range, the raw material component is denatured or a side reaction occurs, so that the desired physical properties and effects cannot be obtained. It is preferable to prepare a cosmetic pack composition within a range.

The deposition step is a step of impregnating or coating the cosmetic pack composition on the substrate by depositing the substrate on the cosmetic pack composition prepared above, wherein the temperature of the cosmetic pack composition may be maintained in the range of 70 to 80°C. When the temperature is lower than 70°C, the viscosity of the cosmetic pack composition increases, making it difficult to impregnate or coat the cosmetic pack composition on the substrate. On the other hand, when it exceeds 80 ℃, there is a problem that the viscosity of the cosmetic pack composition is excessively reduced so that the cosmetic pack composition flows excessively from the substrate, so that it is difficult to control the amount of the cosmetic pack composition impregnated or coated on the substrate.

The drying step is a step for adjusting the moisture content of the cosmetic pack composition to 1 to 10% by weight, preferably 2 to 7% by weight by removing moisture from the cosmetic pack composition impregnated or coated on the substrate, hot air drying, drying under reduced pressure, or It may be performed through a lyophilization method.

Hereinafter, the present invention will be described in more detail through a dry sheet-like cosmetic pack according to an embodiment of the present invention. However, the scope of the present invention is not limited to the following preferred embodiments.

[Production example]

Each raw material was quantified according to the composition ratio of Table 1 below, and mixed at a rate of 1000 rpm at 70° C. for 10 minutes to prepare cosmetic pack compositions of Examples 1 to 4 and Comparative Examples 1 to 5. Thereafter, a non-woven fabric having a thickness of 0.5 mm was immersed in each prepared cosmetic pack composition for 10 seconds, then taken out and dried by hot air at 100° C. for 2 hours to prepare a dry sheet-shaped cosmetic pack.

[Experimental Example]

After using a dry sheet-type cosmetic pack for 30 male and female subjects in their 20s and 30s, the moisture-removing power, emulsifying power, absorption time and moisturizing power of the dry sheet-shaped cosmetic pack were evaluated.

The experiment was performed after resting the subjects for 30 minutes at a constant temperature and humidity condition of 22°C and a relative humidity of 55%, and then washing hands using lukewarm water, while Examples 1 to 4 and Comparative Examples 1 to 1 were wet. After rubbing the dry sheet-like cosmetic pack of Comparative Example 20 20 times on the hand, the amount of moisture remaining in the hand (moisture removal power), the hand's moisture and the degree of emulsification of the cosmetic pack composition were visually observed and evaluated according to the following evaluation criteria. After measuring the absorption time of the applied cosmetic pack composition, the results are shown in Table 3. At this time, the absorption time was measured on the basis of the time when the lightly tapping the hands no longer sticks.

In addition, the moisture content of the hand was measured using a moisture meter Corneometer (CM820PC ^® , Courage Khazka, Germany) before, 20 minutes and 60 minutes after using the dry sheet-shaped cosmetic pack, and the measured capacitance value was arbitrary between 0 and 120. Converted to capacitance units (AU) and the average value is shown in Table 4.

<Evaluation criteria>

○: Excellent, △: Normal, X: Poor

Looking at Table 3, it can be seen that the dry sheet-like cosmetic packs of Examples 1 to 4 exhibit excellent results in terms of moisture removal power, emulsifying power and absorption time remaining in the hand.

On the other hand, it can be seen that Comparative Examples 1 to 5 show poor results in at least one item. These results included the content of the hydrophilic surfactant contained in the total surfactant or the content of tripropylene glycol methyl ether contained in the total moisturizer in an unfavorable range, so that excess moisture attached to the hand was transferred to the dry sheet-like cosmetic pack. It is believed that this is because the efficiency to be reduced decreases and the absorption power of the cosmetic pack composition into the skin decreases.

Looking at Table 4, it can be seen that the dry sheet-like cosmetic packs of Examples 1 to 4 provide superior moisturizing power compared to Comparative Examples 1 to 5.

In particular, looking at the experimental results of Comparative Example 1 and Comparative Example 2 and Examples 1 to 3, when the content of the hydrophilic surfactant exceeds 52 to 66% by weight of the total surfactant content, it can be confirmed that the moisturizing power is poor. there was.

When the hydrophilic surfactant is insufficient, the efficiency of water migration from the skin to the substrate decreases, and it is judged as a result that the moisturizing component evaporates together with evaporation of excess moisture due to the increase in excess moisture remaining on the skin. It is presumed that the result was because the moisturizing component was not properly absorbed by the skin because the excess moisture of the skin and the cosmetic pack composition were not mixed smoothly.

In addition, looking at the experimental results of Example 2, Example 4 and Comparative Examples 3 to 5, it was confirmed that the content of tripropylene glycol methyl ether is slightly lowered when the moisture content exceeds 5 to 16% by weight. These results are presumed to appear because the behavior of the interaction between the surfactant and the total moisturizer changes depending on the content of tripropylene glycol methyl ether.

Therefore, as a surfactant included in the cosmetic pack composition of the dry sheet-like cosmetic pack, a mixture of 52 to 66% by weight of a hydrophilic surfactant having an HLB value of 13 or more and 34 to 48% by weight of a hydrophobic surfactant having an HLB value of 5 or less, is used as a moisturizer. Including propylene glycol alkyl ether (C1-C4), it was found that it is preferable to use 5 to 16% by weight based on the total moisturizer composition.

When such a dry sheet-like cosmetic pack is applied to wet and wet skin, excess moisture attached to the skin can be removed, and some moisture is easily mixed with the cosmetic pack composition to have a moisturizing effect on the skin .

The dry sheet-like cosmetic pack is used in place of a towel to remove moisture from the skin, so that excess moisture attached to the skin can be removed, and a quick, simple, and effective moisturizing effect can be given to the skin.

The present invention is not limited to the specific embodiments and descriptions described above, and various modifications can be carried out by anyone having ordinary knowledge in the technical field to which the present invention pertains without departing from the gist of the present invention as claimed in the claims. And such modifications are within the protection scope of the present invention.
