Description

Manufacturing method of hydrogel composition for shower beauty filter having skin moisturizing effect

The present invention relates to a method for preparing a beauty filter hydrogel composition for a shower having a skin moisturizing effect, after preparing a hydrogel bead mainly composed of alginate, a carrier oil and an emulsifier, and filling it into a liquid hydrogel and UV curing It relates to a method for producing a cosmetic filter hydrogel composition for.

In recent years, the use of a cartridge filled with a cosmetic composition such as an emulsion, a moisturizer, a fragrance, and a bath in a shower or a faucet provided in a bathroom or a washbasin for skin moisturization is increasing. Such cosmetic composition components are eluted in cold water or hot water in the cartridge and discharged from the shower head or faucet, which are usually filled into the cartridge as solid or powder. However, these compositions are too easily dissolved in cold water or hot water, resulting in over-eluting, and the disadvantage of maintaining the solid shape or sustaining the effects thereof is also disadvantageous. For this reason, there is a need for frequent filling of the cosmetic composition in the cartridge, and an unnecessary cost may be generated, and thus, a technology for controlling the solubility of the cosmetic composition for filling such a cartridge is required.

In addition, the sour cartridge filling composition used in the past contains vitamins such as dextrin as an address material, and these compositions are manufactured to produce a water softening effect for improving water quality rather than improving moisturizing function. Although included in such compositions, it was also difficult to expect the moisturizing component to elute evenly in a constant amount.

Accordingly, the present inventors have completed the present invention by establishing a condition in which a moisturizing oil such as a carrier oil is contained in a hydrogel containing alginate as a main material and can be discharged at a constant elution concentration with the shower water.

More preferably ammonium sulfate can be used.

The present invention provides a cosmetic filter hydrogel composition or a cartridge filled with the same for a shower prepared in the above method. Carrier oil may be eluted at 2.5 to 4.0 mg / L in the shower water from the cosmetic filter hydrogel composition or a cartridge filled with the cosmetic filter.

Hereinafter, the present invention will be described in detail.

In the first step of the preparation method of the present invention, polysorbate may be used as the emulsifier used in the preparation of the hydrogel beads or the liquid hydrogel, and may be selected from polysorbate 20, 40, 60, 65, 80, 85. Can be. The weight average molecular weight of the polysorbate is 1500 or less, preferably 500 to 1500, more preferably 1000 to 1500, the viscosity is preferably 100 ~ 600 mPa.s (25 ℃), more preferably Can be used is 250 ~ 450 mPa.s (25 ℃).

The first oil-and-water dispersion composition for preparing hydrogel beads may be prepared by mixing 10 to 30 wt% of an emulsifier, 1 to 5 wt% of an ionic crosslinked polymer, and 10 to 30 wt% of a carrier oil in purified water. In this case, when the content of the emulsifier is less than 10% by weight, the carrier oil may not be mixed with the oil-and-water dispersion composition, and when the emulsifier exceeds 30% by weight, the formation of beads is not preferable, which is not preferable. When the ionic crosslinked polymer is also mixed at less than 1% by weight, the formation of beads may be difficult, and when it is more than 5% by weight, carrier oil may not be easily eluted from the beads. Even when the carrier oil is less than 10% by weight, less moisturizing component is eluted from the beauty filter for shower, and when it is more than 30% by weight, separation of the oil-and-water dispersion composition may result in poor bead formation.

Hydrogel beads may be prepared by dropping the mixed first oil-dispersed dispersion composition in an aqueous solution of 1 to 5% by weight of calcium chloride. If the concentration of calcium chloride in the aqueous solution of calcium chloride is less than 1% by weight, beads may not be formed well. And, if it exceeds 5% by weight, it is not preferable because the carrier oil in the bead of the final cosmetic cosmetic filter for the shower may not be well dissolved.

The oil- and water-dispersion composition for preparing the hydrogel beads may be added dropwise into the aqueous calcium chloride solution through an outlet having a diameter of 0.4-1.5 mm (more preferably 1.0-1.5 mm) at a rate of 0.05-0.4 mL / min. However, when the dropping speed and the size of the discharge portion are different, the carrier oil is excessively eluted or is too small in the final cosmetic filter hydrogel composition, which is not appropriate.

In addition, in the first step, the oil-and-water dispersion composition for preparing the liquid hydrogel may be 30 to 60% by weight of the emulsifier, 1 to 5% by weight of the ionic crosslinked polymer and 10 to 30% by weight of the carrier oil in purified water. When the content of the emulsifier is less than 30% by weight, the carrier oil may not be mixed in the oil-and-water dispersion composition, and when the emulsifier exceeds 60% by weight, the formation of the liquid hydrogel is not preferable, which is not preferable.

If the ion crosslinked polymer is also mixed at less than 1% by weight, the formation of the liquid hydrogel may not be good, and if it exceeds 5% by weight, the carrier oil may not be easily eluted from the final cosmetic filter for shower. . Even when the carrier oil is less than 10% by weight, less moisturizing component is eluted from the final cosmetic filter for shower, and when it exceeds 30% by weight, liquid separation does not form well due to layer separation in the oil-and-water dispersion composition. Can be.

5 to 20 parts by weight of acrylamide-based monomers, 10 to 20 parts by weight of a chemical crosslinking agent, 0.5 to 3 parts by weight of an ion crosslinker, and 0.5 to 3 parts by weight of a photoinitiator may be mixed based on 100 parts by weight of the oil-and-water dispersion composition for preparing a liquid hydrogel. If the acrylamide monomer is less than 5 parts by weight, the chemical crosslinking agent is less than 10 parts by weight, the ion crosslinking agent is less than 0.5 part by weight, and the photoinitiator is less than 0.5 part by weight, the curing of the hydrogel using ultraviolet rays may be difficult and the elution of the carrier oil may occur. This may be too excessive and undesirable. In addition, when the acrylamide-based monomer exceeds 20 parts by weight, even if the chemical crosslinking agent exceeds 20 parts by weight, the ion crosslinking agent 3 parts by weight, the photoinitiator exceeds 3 parts by weight, the viscosity or strength of the hydrogel inhibits the elution of the carrier oil It may not be desirable.

When the hydrogel beads and the hydrogel are mixed in the second step, the hydrogel beads may be mixed in an amount of 5 to 12 wt%. Only when the hydrogel beads and the hydrogel are mixed within such a range, the carrier oil may be eluted in an appropriate amount to increase the life of the filter composition, while maintaining a constant skin moisturizing effect due to the carrier oil.

The hydrogel bead is characterized in that the spherical bead having a particle size of 1.0 ~ 3.0 mm radius. If the radius is less than 1.0 mm, dissolution of the moisturizing component such as carrier oil may occur excessively, and even if it exceeds 3.0 mm, the eluting of the moisturizing component may not be well performed.

When the hydrogel beads and the hydrogel are mixed in the second step, the hydrogel beads may be mixed in an amount of 5 to 12 wt%.

The ion-crosslinked polymer, which is a water-soluble polymer used in the present invention, includes a carboxylic acid functional group and enables the production of a hydrogel that is insoluble in water (ion crosslinking) by using a polyvalent cation such as Ca ²⁺ or Fe ³⁺ as a crosslinking agent. .

Hydrogel beads prepared in the present invention can be prepared in a state containing a carrier oil using an external gelation method. In the external gelation method, a salt containing a polyvalent cation is dissolved in water, and then a volume of ionic crosslinked polymer solution is added dropwise to cause ion crosslinking from the surface to form beads, and then calcium ions are diffused into the beads, thereby causing crosslinking reaction to the inside of the beads. That's how it happens. Therefore, a dense structure of hydrogel matrix is formed on the surface, and a relatively loose structure is formed on the center portion. When the solution containing the ionic crosslinked polymer is dropped, the size of the hydrogel beads is controlled by controlling the diameter size and the ejection speed of the nozzle for discharging the ionic crosslinked polymer solution. This can have the greatest impact on speed control.

The composition of the liquid hydrogel constituting the filter composition in the present invention is similar to the hydrogel beads, but covalent bonds (chemical crosslinking) are present at the same time, ie, having a physicochemically stable interpenetrating polymer network structure Have This can be explained through the hydrogel schematic diagram of the alginate and acrylamide and calcium ions in the upper part of FIG. 1. 1 discloses that the final filter composition is prepared by mixing the hydrogel and the hydrogel beads thus prepared.

By using the method of the present invention, the cosmetic filter composition for a shower is manufactured in a state in which a hydrogel bead and a hydrogel are mixed, so that the breakdown and abrasion of the hydrogel constituting the filter composition are less likely to be used. The ability to continuously elute the carrier oil in the shower or faucet for a period of time.

The present invention relates to a method for preparing a hydrogel composition for a shower having a skin moisturizing effect. According to the present invention, a hydrogel bead mainly composed of alginate, a carrier oil, and an emulsifier is prepared, and then filled into a liquid hydrogel to prepare a cosmetic filter hydrogel composition for a shower, and thus various skin such as carrier oil included in the composition. It is possible to provide a beauty filter for a shower that can be eluted at a uniform concentration for a moisturizing substance.

Hereinafter, a preferred embodiment of the present invention will be described in detail. However, the present invention is not limited to the embodiments described herein and may be embodied in other forms. Rather, it is provided to fully convey the spirit of the present invention to those skilled in the art so that the contents introduced herein are thoroughly and completely.

<Example 1. Confirmation of manufacturing conditions of hydrogel beads for each type of emulsifier>

Olive emulsifiers (olive oil PEG-7 esters), solubilizers (polysorbate 80 [Tween 80]), cetyl alcohol, montanwax-68 (cetiarylglucoside), carbomer pregel (carbomer 980, Carboxyvinyl polymer) was prepared, and a mixed solution (oil-water dispersion composition) in which 2wt% alginate, 20wt% jojoba oil golden, and 20wt% emulsifier was mixed for each emulsifier was prepared. The state of the mixed solution for each emulsifier is shown in FIG.

A syringe pump was used to disperse the mixed solution droplets in a 1.5 wt% aqueous solution of CaCl ₂ through a nozzle at a constant discharge rate. The speed of the syringe pump was fixed at 0.4 mL / min, the diameter of the discharge nozzle (syringe needle) was 1.27 mm, and the CaCl ₂ aqueous solution in which the mixed solution was added was stirred at a speed of 200 rpm.

In the mixed solution, a hydrogel membrane was formed by ion bonding from the surface thereof, and calcium ions penetrated into the inside to diffuse ionic bonds to form hydrogel beads.

The resulting hydrogel beads were collected to measure the radius of the hydrogel beads prepared for each emulsifier and are shown in Table 1 below, and the shape immediately after the preparation was shown in FIG. 3.

Emulsifier Bead size (radius, mm) 30 minutes after manufacture Olive Liquid (from Olive) 1.166 ± 0.025 Good Solubilizer (from castor oil) 1.312 ± 0.038 Good Cetyl Alcohol (from Coconut) 1.181 ± 0.043 Good Montanov Wax 68 (from Palm and Coconut) 1.350 ± 0.033 Good Carbomer Freegel 1.354 ± 0.075 Phase separation of jojoba oil, carbomer pregel and hydrogel

Referring to Table 1 and FIG. 3, it can be seen that all five types of beads have a uniform size of hydrogel beads, regardless of the type of emulsifier. However, in the case of beads containing carbomer freegel, after about 30 minutes, the cracks in the beads, phase separation of jojoba oil, carbomer pregel, hydrogel occurred. In the mixed solution before the bead preparation, the solution containing the carbomer freegel was clearly formed after 30 minutes of solution preparation, resulting in phase separation, and the carbomer freegel did not play an appropriate role as an emulsifier.

Meanwhile, in the case of cetyl alcohol and Montanowax 68, it has the disadvantage of having to be heated for more than 1 hour at a temperature of 80 ° C. or more when preparing a mixed solution as a solid emulsifier. Was also confirmed.

Therefore, it was determined that olive liquid and solubilizer emulsifiers in general are easy to use and suitable for producing uniform hydrogel beads.

<Example 2. Confirmation of formation conditions of hydrogel beads according to the dropping rate>

Hydrogel beads were prepared using the olive liquid and the solubilizer emulsifier in the same manner as in Example 1 except that the nozzle discharge rate of the mixed solution was changed. The discharge rate of the pump to which the nozzle is connected was adjusted to 0.4 (Example 1 condition), 0.1, 0.05, and 0.01 ml / min, respectively, and the size of beads generated according to the discharge rate (dripping speed) is shown in Table 2.

Emulsifier Discharge Rate (ml / min) Bead size (radius, mm) Olive Liquid 0.40 1.166 0.10 0.987 0.05 0.743 0.01 0.654 Solubilizer 0.40 1.312 0.10 1.123 0.05 1.098 0.01 0.954

Referring to Table 2, it can be seen that as the syringe discharge speed decreases, the dropping speed of the mixed solution decreases and the size of the hydrogel beads decreases.

In addition, the elution experiment of jojoba oil was carried out using the hydrogel beads thus prepared, and the results thereof are shown in FIGS. 4 (olibriquid-containing beads) and FIG. 5 (beads containing solubilizer). The elution characteristics of the hydrogel beads were 5 g hydrogel beads in 100 mL distilled water and the solution was sampled every 15 minutes while stirring at a constant speed of about 100 rpm. Then, the absorbance was measured by UV-Vis spectrometer to measure the concentration of the released components. The dissolution experiment was performed for a total of 120 minutes.

Referring to Fig. 4 (beads containing oligoquidide) and Fig. 5 (beads with solubilizer), the results of the experiment at the same total weight of the beads, the dissolution rate due to the increase in the surface area as the size is smaller in the case of using the solubilizer It was confirmed that the phenomenon of constant increase, and a sudden change in the dissolution rate, without showing a pattern of the carrier oil is eluted at a constant rate, it was confirmed that the use of a solubilizer is more stable.

These results determined that the most preferred emulsifier for the preparation of hydrogel beads is the use of a solubilizer.

<Example 3. Confirmation of formation conditions of hydrogel beads according to the size of the discharge port>

Hydrogel beads were prepared using an olive liquid and a solubilizer emulsifier in the same manner as in Example 1 except that nozzles of various diameters were used. The discharge rate of the syringe pump was fixed at 0.4 ml / min, and injection needles having internal diameters of 0.42, 0.63 0.83, and 1.27 mm were used as nozzles.

Pictures and sizes of the beads generated by the nozzles are shown in FIG. 6 (beads containing oligoquidide) and FIG. 7 (beads containing solution). 6 and 7 it can be seen that as the diameter of the nozzle discharge port is smaller, the diameter of the hydrogel beads decreases due to the reduction of the discharge amount.

Example 4 Preparation of Ultraviolet Cured Hydrogel

Olive oil (olive oil PEG-7 esters) and a solubilizer (polysorbate, Tween 80) are prepared as an emulsifier, and for each emulsifier, 2wt% alginate, 20wt% jojoba oil golden and an emulsifier are mixed. A mixed solution (oil-water dispersion composition) on a gel to form a micelle was prepared. The emulsifiers were comprised of 20 wt%, 40 wt% or 60 wt%, respectively. At this time, alginate was first mixed with water, and jojoba oil and emulsifier were mixed sequentially.

Also, 14.2 g of acrylamide monomer, 1.4 g of N, N-methylenebisacrylamide as a chemical crosslinking agent, 0.3 g of CaSO ₄ as a crosslinking agent for ionic crosslinking, and 0.8 g of ammonium persulphate as a photoinitiator were added to 100 g of the composition mixed up to the emulsifier.

After the photoinitiator was added, the prepared solution (liquid hydrogel) was filled in a transparent filter case (cartridge) and subjected to chemical crosslinking reaction through UV irradiation (lamp power = 1 kW) for 15 minutes, and the hydrogel filter prepared after the crosslinking reaction. The dissolution test was carried out for 30 minutes at 0.5 L / min flow rate conditions were inserted into a sour specification experimental apparatus as shown in FIG. The amount of oil eluted was quantitatively analyzed using UV / Vis spectroscopy, and the results are shown in FIG. 9.

As shown in FIG. 9, the oil dissolution rate showed a tendency to decrease as the proportion of the emulsifier was increased. When olive liquid was used, the dissolution rate was too high compared to the use of the solubilizer. The change in dissolution rate according to the type of emulsifier can be considered to be affected by the viscosity of the emulsifier and the affinity with the hydrogel component. Therefore, when olive liquid is used as an emulsifier, it is expected that the use time of the filter will be shortened by greatly exceeding the required dissolution rate.

On the other hand, when the weight ratio of the carrier oil and the solubilizer is 1: 1, the initial dissolution rates were similar to 1: 2 and 1: 3, but the phase separation occurred over time. It was found not to be appropriate.

Therefore, it can be seen that the solubilizer is also preferable as an emulsifier for preparing UV-cured hydrogel, and the weight ratio of the carrier oil and the emulsifier is preferably determined in the range of 1: 2 to 1: 3.

<Example 5. Preparation of UV cured filter composition after mixing hydrogel and hydrogel beads>

It can be assumed that the average amount of water used by a person in a single shower is 50 liters on average and the use time is 10 minutes on average. At this time, if the moisturizing oil content of the filter is 20 ~ 30 wt%, the amount of elution required when the filter is used by two people for at least five months is in the range of about 2.5 ~ 4.0 mg / L. Therefore, to more effectively control the dissolution rate, the following experiment was performed.

In the method of Example 4, the weight ratio of jojoba oil and solubilizer emulsifier was adjusted to 1: 2.5 (20wt%: 50wt%) to prepare a liquid hydrogel (performed immediately before UV irradiation).

The hydrogel beads were prepared under the conditions shown in Example 3 using the solubilizer as an emulsifier (jojoba oil: emulsifier = 1: 1 weight ratio), and the discharge rate of the syringe pump was fixed at 0.4 ml / min, and the discharge port diameter was 1.27. A hydrogel bead having a radius of 1.02 mm and a hydrogel bead having a radius of 0.95 mm, respectively, were prepared using a needle of mm and a needle of 0.42 mm.

Next, the liquid hydrogel and the hydrogel beads thus prepared were mixed at a predetermined ratio, and the cartridge was filled into a cartridge to prepare a cured filter composition in which the hydrogel beads were mixed (bonded) in the hydrogel through UV irradiation. The radius of the hydrogel beads in the composition first used was about 1.02 mm, the bead content was adjusted to 5, 7, 10, 12, 15% by weight.

The final filter composition was inserted into an experimental apparatus of a sour specification as in Example 4, and the dissolution experiment was performed for 120 minutes at a flow rate of 0.5 L / min. The amount of oil eluted was quantitatively analyzed using UV / Vis spectroscopy.

Bead content, total oil content and average elution amount contained in the filter composition are shown in Table 3.

Bead content (wt%) Total Jojoba Oil Content (wt%) Average elution amount (mg / L) 5 21.1 2.79 7 23.3 2.72 10 25.4 2.66 12 27.5 2.58 15 29.7 2.41

Referring to Table 3, the oil content of the filter increases as the content of the hydrogel beads increases, but the average elution tends to decrease as the content of the beads increases. By combining, the total content of the moisturizing oil (jojoba oil) of the filter can be increased and at the same time, the moisturizing oil component can be adjusted to a proper dissolution rate range while double-passing the hydrogel barrier of the beads and the matrix.

As a result, when the hydrogel bead content is 5 to 12% by weight, it can be confirmed that the elution amount between 2.5 and 4.0 mg / L, which is a proper dissolution rate when the minimum daily usage is based on the average daily water usage, is 5 months. have.

Next, the same experiment was performed, but after the beads and gels were filled in the filter using a hydrogel bead having a radius of 0.95 mm, the elution rate of jojoba oil was found to exceed 5.0 mg / L. Therefore, it was found that the elution amount of the carrier oil component was controlled only when the radius of the hydrogel beads was at least 1.0 mm. The radius of the hydrogel bead is more than 1.0mm when using the solution of the emulsifier, when referring to Table 2 and Figure 5, the discharge rate 0.05 ~ 0.4ml / min, when referring to Figure 7, manufactured under the conditions of the nozzle diameter 1.27mm It is confirmed when it is done.

<Experimental Example 1 Experiment to Check Skin Moisture Condition (Moisturizing Effect) by Using Filter>

The filter composition was prepared by UV curing under the conditions mixed with the liquid hydrogel so that the hydrogel beads contained 12% by weight, as shown in Table 4, and each filter product was used in five households per group (two households, averaged over three months). The water usage, the number of showers, and the shower time were similar, and the test was performed for 8 weeks, and the skin condition before and after each filter product was checked.

Skin moisture measurement was confirmed using a Corneometer (CM825, Courage and Khazaka Electronic Co., Germany). Measured before and after 8 weeks of product use, the average value was calculated using three values measured by Corneometer. The higher the moisture content, the higher the measured value, and the measured coefficient is Arbitrary unit (A.U.). In addition, the results thus obtained were confirmed in terms of skin moisture improvement effect (fold).

* The results in Table 4 are shown as fold values based on 1.0 of skin moisture state before filter use.

In addition to the experimental skin moisturizing condition, the degree of skin improvement felt by the user is calculated by a 5-point RBI method (5 points: very good, 4 points: good, 3 points: normal, 2 points: bad, 1 point: very bad). Checked after weeks and the results are shown in Table 5 below.

The results of Table 4 and Table 5 showed that the bead prepared using the solubilizer emulsifier had a better moisturizing effect than the olive liquid as an emulsifier, in addition to the moisturizing effect promoted by jojoba oil. The type also affected the skin moisturizing. This is because the solubilizer instead of olive liquid maintains the state of the hydrogel beads more stable.

Meanwhile, in addition to this experiment, the same experiment was performed by replacing the emulsifier with olive liquid instead of the solubilizer when preparing the liquid hydrogel, but the hydrogel composition was rapidly exhausted within 1 month, and the result was not described thereafter. The use of olive liquid in the preparation did not carry out additional experiments.

Experimental Example 2. Confirming the Filter Composition Exhaust Period

The filters described in Table 5 were used continuously after checking the skin condition to confirm the period until the filter composition was completely exhausted (the content of the composition filled in each filter was the same).

Referring to the results of Table 6, it was found that the filter composition used as the solubilizer as the emulsifier satisfies the target filter exhaustion period of 5 months, and it can be confirmed that the filter can be used for a long period of time while providing an excellent moisturizing effect.

According to the user's explanation, the filter composition using olive liquid as an emulsifier of hydrogel beads through the touch after showering felt a lot of moisturizing ingredients eluted immediately after use, but it was confirmed that the elution of the moisturizing ingredients decreased significantly as it flowed. It became. However, it has been explained that, for a filter user using a solubilizer as an emulsifier, it is possible to use a shower water in which the same moisturizing component is eluted.

In addition, it can be seen that the mixture of the hydrogel beads and the liquid hydrogel increases the service life than when the hydrogel beads or the liquid hydrogel are used alone.

It was confirmed that the initial dissolution rate of the oil was similar to that of the mixed state when the liquid hydrogel was used alone, but the sustainability of the gel phase composition with the long term use was the best in the hydrogel beads or the liquid hydrogel mixing conditions. It became.

Therefore, when using the filter composition mixed under the conditions of the present invention, it can be seen that the most suitable condition is that the moisturizing substance such as jojoba oil is sustained-release to the shower water.
