[0013] As described above, the method for producing Epsom salt cream containing Epsom salt according to the present invention allows for the highly efficient production of Epsom salt cream. Therefore, this offers the advantage of being able to manufacture Epsom salt cream containing Epsom salt that can maintain its quality over a long period of time while significantly reducing costs. Moreover, by manufacturing an Epsom salt cream containing the Epsom salt of the present invention, it becomes possible to incorporate the Epsom salt not only at a low concentration of 0.1% to less than 5%, but also up to a high concentration of about 5% to 25%.

[0014] The Epsom salt cream obtained by the method for producing an Epsom salt cream containing the Epsom salt of the present invention exhibited the following effects as a cosmetic product. (a) It can keep the skin healthy. (b) It can supplement and retain moisture and oil. (c) It can prevent dryness.

Embodiments for Carrying Out the Invention

[0015] Hereinafter, embodiments of the method for producing an Epsom salt cream containing the Epsom salt of the present invention will be described in detail based on examples.

[0016] An example of the steps of the method for producing an Epsom salt cream containing the Epsom salt of the present invention is as follows. 1) First, a preparation A containing shea butter as the main component, olive oil, petrolatum, beeswax, and an emulsifier, and a preparation B obtained by dissolving magnesium sulfate (Epsom salt) in water and adding BG (1,3 - butylene glycol) and sodium ascorbate are prepared. At this time, in the preparation A, as the emulsifier, cetearyl olive oil fatty acid and sorbitan olive oil fatty acid (manufactured by Matsumoto Trading Co., Ltd., trade name "Oleum 1000") can be preferably used. Also, in the preparation B, as the magnesium sulfate, "Epsom Salt Seakrystal" (registered trademark) manufactured by Hirose Co., Ltd. can be preferably used.

[0017] 2) Next, in the production, first, the preparation A is completely dissolved and mixed at 80°C or higher. 3) Separately, stir and mix agent B at room temperature until it is completely dissolved. Furthermore, if the above-mentioned Agent B contains a high concentration of magnesium sulfate (5% to 25%), it is preferable to raise the temperature to 60°C or higher and stir-fry the mixture in step 3) above. 4) While keeping the dissolved agent A in step 2) above at 75°C or higher, add the agent B in step 3) above in small amounts and emulsify and mix. 5) After that, the material obtained in step 4) is cooled to 40°C to 50°C, and then emulsified by stirring at 600 revolutions per minute for 20 seconds, followed by stirring at 2000 revolutions per minute for 2 minutes. 6) Finally, add the preservative, thickener, and antioxidant and stir. Furthermore, phenoxyethanol can be suitably used as the preservative, xanthan gum as the thickening agent, and tocopherol as the antioxidant.

[0018] Thus, the method for producing Epsom salt cream containing Epsom salt according to the present invention allows for the highly efficient production of Epsom salt cream, resulting in significant cost reductions and enabling the production of Epsom salt cream that maintains its quality over a long period of time.

[0019] Furthermore, in the aforementioned Agent B, even at a low concentration of 0.1% to less than 5% relative to the total amount of Epsom salt cream obtained by the manufacturing method of the present invention, a certain degree of effect and noticeable results can be obtained. However, by using a high concentration of 5% to 25%, the following effects and noticeable results can be obtained more significantly than in the low concentration range. (a) It can keep the skin healthy. (b) It can replenish and retain moisture and oil. (c) It can prevent drying.

[0020] It has been found that if the magnesium sulfate content exceeds 25%, the cream's smoothness and other usability issues are impaired. Furthermore, if the content is increased to over 30%, a white powder precipitates when applied to the user's skin, which is undesirable.

[0021] The following are specific examples of formulations for the aforementioned Agent A and Agent B. [Table 1]

[0022] The combination of sodium ascorbate, BG (1,3-butylene glycol), and the divalent metal salt magnesium sulfate (Epsom salt) improves storage stability while maintaining its effectiveness as a cosmetic. In other words, (a) It can keep the skin healthy. (b) It can replenish and retain moisture and oil. (c) It can prevent drying. While these effects can be felt even when magnesium sulfate (Epsom salt) is incorporated at low concentrations of 0.1% to less than 5%, the effects can be fully felt by incorporating high concentrations of magnesium sulfate, particularly 12% to 18%, using the method for producing Epsom salt cream containing Epsom salt according to the present invention.

[0023] As mentioned above, the above-mentioned effects can be fully obtained and felt when the magnesium sulfate content is in the high concentration range of 5% to 25%. However, according to the inventor's survey, 70% of users responded that they were able to fully obtain and feel the above-mentioned effects when the magnesium sulfate content was in the high concentration range of 12% to 18%. Therefore, it is considered that setting the magnesium sulfate content in the high concentration range of 12% to 18% is preferable. Furthermore, among the user responses, the magnesium sulfate concentration that received the most positive feedback was 14.9%. It was found that when the magnesium sulfate concentration was 14.9%, the Epsom salt cream, in particular, performed well, and when applied to the skin, the magnesium sulfate did not precipitate, resulting in a smooth application. Therefore, by setting the magnesium sulfate content to 14.9%, even within the high concentration range of 5% to 25% magnesium sulfate content, (a) It can keep the skin healthy. (b) It can replenish and retain moisture and oil. (c) It can prevent drying. This is a remarkable effect and a noticeable result, This method allows for the optimal balance of factors such as the cream's storage stability, smoothness, ease of application to the skin, and skin penetration. [Industrial applicability]

[0024] As can be understood from the above explanation, the method for producing Epsom salt cream containing Epsom salt according to the present invention was obtained as a result of diligent research on cosmetic applications, and it was found that the above-mentioned conditions are optimal for such applications. Therefore, a method for producing an Epsom salt cream containing Epsom salt that is efficient and safe can be obtained.
