Embodiment 1

[0044] Example 1: Preparation of hydrogel through phase transition temperature emulsification process

[0045] From the composition of Table 1 below, the following materials were prepared.

[0046]Put mineral oil (Mineraloil), ceteth-20 (Ceteth-20), steareth-20 (Steareth-20) and stearin into another oil phase dissolving tank Glyceryl Stearate, Cetearyl Alcohol, and preservatives were heated and dissolved to a temperature of 70-85°C, and then additionally heated purified water was added to prepare an oil-in-water type phase transition temperature emulsion. Here, the water-soluble gelling polymer, polyhydric alcohol, and other additives heated / dissolved in a separate water-phase dissolution tank are added, heated sufficiently, and then stirred. Then, after throwing the phase transition temperature emulsion into the above-mentioned water phase dissolving tank, it is cooled to 60 to 80° C., and the phase transition temperature emulsion is immersed in the gelled product (aqueou...

Embodiment 2

[0050] Example 2: According to the type and content of water-soluble gelling polymer and emulsification by phase transition temperature Procedure for the preparation of the hydrogel

[0051] The composition of the following Table 2 was prepared in the same manner as that of Example 1.

[0052] 【Table 2】

[0053] Water phase

[0054] mineral oil

[0055] As a result, it can be known that image 3 and Figure 4 As shown, a milky white and elastic dosage form is completed.

Embodiment 3

[0056] Example 3: Phases determined by the type of water-soluble gelling polymer, the type of oil, and the content of the oil phase Preparation of hydrogel by transition temperature emulsification process

[0057] The composition of the following Table 3 was prepared in the same manner as that of Example 1.

[0058] 【table 3】

[0059] Water phase

[0060] As a result, such as Figure 5 and Figure 6 As shown, depending on the type of oil and increasing the content of the oil phase, the degree of suspension changes, but emulsion-type hydrogels can be prepared.

Abstract

The invention relates to a production method for hydrogel mask having outstanding skin-improving effect while comprising a large oil fraction, and a hydrogel composition produced by means of the method. The present invention specifically relates to a hydrogel composition using a phase inversion temperature (PIT) emulsification process and to a production method for same. More specifically, the invention relates to a method wherein a water-based moiety comprising a water-soluble gelling polymer, purified water, a polyhydric alcohol and other additives is heated/stirred at between 60 and 100 DEG C and, in a separate container, an oil-based moiety comprising a nonionic surfactant and an oily skin-softening agent is heated to between 60 and 95 DEG C, and then the water-based moiety and the oil-based moiety are mixed and cooled to a temperature range at which the water-based moiety gells, namely between 60 and 80 DEG C, and at the same time a PIT emulsion is stably impregnated into the gelled article, cooling takes place via a cooler, and a hydrogel is moulded. The present invention makes it possible to achieve more effective skin penetration of active ingredients in the nano-emulsion state, and thus to enhance the effects thereof, by using the PIT emulsification method to make it easier to include oil fractions in hydrogels in which it has previously been difficult to include oil fractions.

Description

technical field [0001] The present invention relates to a hydrogel preparation method and a hydrogel composition prepared therefrom, more particularly to a hydrogel composition (Hydrogel) preparation method through a phase inversion temperature (Phaseinversiontemperature) emulsification process and a hydrogel composition prepared therethrough Gel composition. Background technique [0002] In addition to the basic aging factors, modern people are also suffering from serious skin damage due to the polluted external environment, life stress, and increased frequency of use of cosmetic products. In order to overcome the above problems, various skin care products such as lotions, creams, essences and dermatological treatments are used. However, when only skin care products are used, skin penetration is limited due to the characteristics of skin tissue, and it is difficult to expect immediate skin improvement. As a result, dangerous operations such as expensive dermatology treatm...
