Description

Functional mask pack and its manufacturing method {functional mask pack and method of preparing the same}

The present invention relates to a functional mask pack to which a material having antimicrobial properties is applied while emitting far infrared rays and a manufacturing method thereof.

In general, a mask pack can supply various nutrients and moisture to the skin, and is a kind of cosmetics using a sheet made to fit the shape of the face. Currently, many high-functional mask packs are being developed by companies that transcend the purpose of supplying nutrients and moisture.

The first-generation mask pack is based on applying and washing the face using natural materials, and mainly used gold, fruit, plants, grains, etc., and with the advent of the second-generation mask pack called sheet mask in the 1990s. As a mask developed from a non-woven fabric pack coated with a liquid such as a skin to a sheet of cotton was developed, the pack developed into a pack with better absorption and higher adhesion than before. The 3rd generation came out with a hydrogel mask pack using cotton and natural gum developed in 2004, and the biocellulose mask pack using natural materials, which is the 2.5th generation intermediate step between the 2nd and 3rd generation, was developed in 2007. Due to the nature of manufacturing, a lot of wastewater and pollutants appear, and it is currently dependent on imports.

On the other hand, far-infrared is a kind of electromagnetic wave, which means that it spreads as a wave in electric and magnetic fields. Infrared, to which far infrared rays belong, means rays outside the red of visible light, and electromagnetic waves with a longer wavelength than red. Of these infrared rays, the farthest from the visible ray, that is, the longer wavelength is defined as far infrared ray. The biggest feature of this far infrared ray is that it has a great thermal effect and has a strong penetrating power, giving the skin a warm feeling. Therefore, in places such as Jjimjilbang, rooms were constructed using mackbanseok or ocher, and this is the reason to emit far infrared rays. As the ultimate efficacy due to the far-infrared heat action, it helps to remove bacteria that cause various diseases, and expands capillaries to help blood circulation. In addition, it has a great effect on sweating or relieving pain, and has many effects such as removal of heavy metals, sound sleep, deodorization, prevention of mold propagation, and air purification.

Therefore, in the prior art, there are cases in which mask packs such as moisturizing skin are manufactured using ocher, mud, minerals, etc. However, since harmful substances exist in ocher or mud, they are toxic and should be used to neutralize these toxicity. Accordingly, there is a problem that it takes a lot of time and money to remove the toxicity of ocher, and the ocher has a drawback such as difficult to emit a sufficient amount of far infrared rays at room temperature because an appropriate amount of far infrared rays are emitted at a temperature of 90 ° C. However, the use of minerals is limited in application to disposable mask packs because expensive materials must be used.

Therefore, there is an urgent need for alternative materials that can exhibit far-infrared effects without toxicity.

Hereinafter, with reference to the embodiment of the present invention will be described in detail. In describing the present invention, when it is determined that a detailed description of a related known configuration or function may obscure the subject matter of the present invention, the detailed description will be omitted.

It will be described as follows through an example of a method for synthesizing polyphosphoric acid through a single process using phosphoric acid as a monomer as shown in Reaction Scheme 1 below.

<Scheme 1>

The polyphosphoric acid synthesized in Reaction Scheme 1 was dissolved in water together with oligosaccharides so that it could be coated well on the mask pack, and their properties and properties were evaluated. The coating was directly coated on the nonwoven fabric to confirm the presence or absence of coating. In addition, the far-infrared emission amount of the nonwoven fabric coated with polyphosphoric acid and oligosaccharide was measured, and antibacterial activity was confirmed. By determining the blending ratio of oligosaccharides as well as materials that can be used as other types of binders and directly coating them to confirm their morphology through SEM, it was confirmed which binder and which proportion is the most suitable blending ratio.

<Example 1> Preparation of polyphosphoric acid

4 kg phosphoric acid (75% aqueous solution) was added to the reactor and 1 kg of urea was added. The temperature of the reaction tank was maintained at 150 ° C. for 4 hours, and ammonia gas was discharged during the reaction time. After discharging all the gases, the remaining precipitate was filtered and dried to obtain polyphosphoric acid. yield; 83%

As shown in Reaction Scheme 1, the process of preparing polyphosphoric acid is very simple and has the advantage of being particularly easy for mass synthesis. 1 (a) shows the results of the elemental analysis, and it can be seen that a high far-infrared emission can be expected because the phosphorus content is very high, and FIG. 1 (b) shows the pH, viscosity, solubility, and solid content of the solution. In the case of pH, when a polyphosphoric acid solution is used as a mask pack, a pH that is too high or too low can cause serious damage to the skin, so an appropriate pH is required. .

The viscosity showed a high value of 56 cPs and the solubility showed a high solubility of 64.9 g / 100 mL. The solids content was 35%, which requires a high viscosity, solids content, and high solubility when coating polyphosphoric acid on the mask pack to effectively coat a large amount.

<Example 2>

As can be seen in Figure 2, the mask pack was prepared by coating with a solution of polyphosphoric acid and oligosaccharide. Coating was performed by simply immersing the material to be coated in the solution for 30 minutes, then taking it out and drying it.

<Example 3>

The dried mask pack was sealed after immersing a composition containing active ingredients such as skin moisturizing, wrinkle improvement, and whitening.

The mask pack prepared according to Example 2, as shown in Figure 2, it can be confirmed that it does not significantly affect any color change or physical properties after coating.

In addition, as a result of testing the far-infrared emission amount of the non-woven fabric coated with polyphosphoric acid, the far-infrared emission amount was measured by directly requesting the analysis of the non-woven fabric coated with polyphosphoric acid directly from the Korea Far Infrared Association.

In addition, the antibacterial properties of polyphosphates against bacteria ATCC 6538 and ATCC4352 were tested. The antimicrobial properties were measured by directly requesting the analysis of polyphosphoric acid from the Korea Research Institute of Standards and Standards, and as a result, as shown in FIG. 3, it can be seen that the reduction rate of bacteria is high at 99% due to the far-infrared emission effect.

In order to apply to the mask pack, materials mixed with polyphosphoric acid and used as binders were tested at different blending ratios. Table 2 below shows the types of binders that are compatible with polyphosphoric acid and the blending ratio of high compatibility.

Starch β-Cyclodextrin oligosaccharide polyphosphoric acid
(in 100 mL H ₂ O) One 0.5 g 0.5 g 0.5 g
50 g 2 1.0 g 1.0 g 1.0 g 3 1.5 g 1.5 g 1.5 g

After coating the non-woven fabric with polyphosphoric acid and a binder, the morphology thereof was observed with a scanning electron microscope (SEM). (See Fig. 4) As a result, the coated non-woven fabric showed a distinctly different morphology compared to the non-woven fabric which did not process anything. In addition, the higher the amount of the binder added, the higher the density of the coating, and the proportion of the binder was 1 to 3 parts by weight compared to 100 parts by weight of polyphosphoric acid. It was found that when the amount of the binder added was 3 parts by weight or more, the efficiency of the coating was lowered. In addition, considering that the functionality of the mask pack is further improved when the addition ratio of the polyphosphoric acid is higher than that of the binder, it is most preferable when the ratio of the binder is 1 to 2 parts by weight.

On the other hand, cosmetic ingredients were added to prepare a final mask pack, and a composition having sodium polyphosphate salt and oligosaccharide as main components was prepared as shown in the following table.
