As shown in Table 5, Comparative Example 3 and Comparative Example 4, which does not contain isopropyl myristate or isononylisononanoate and hyaluronic acid having excellent compatibility with silicone oil, even if the amount of the emulsifier is increased over time. As a result, the viscosity decline was remarkable, and the emulsified particles felt the unity of the water droplets, and the absolute value of the zeta potential was low.

In contrast, Examples 4 to 6 to which isopropyl myristate, isononyl isonanoate, or hyaluronic acid were added did not change the viscosity, emulsified particles, and zeta potential values over time. In Example 4 and Example 5, the union of the water droplets was not observed, but in Example 6, in which the hyaluronic acid was not included, it was found that the union of the water droplets was somewhat observed, and the absolute value of the zeta potential was somewhat lower. In addition, when comparing the results of Example 4 and Example 5, it was found that isopropyl myristate is more effective in stability than isononylisononanoate. From these results, it was found that the deterioration in stability over time was not solved by an increase in emulsifier, and when hyaluronic acid and isopropyl myristate were further included, stability problems, such as preventing unity of particles and a decrease in viscosity, were solved.

As a result of the synthesis of the above embodiments, it can be confirmed that by using erythritol or betaine as a moisturizing agent and further including hyaluronic acid and isopropyl myristate, it is possible to obtain a make-up cosmetic composition having excellent moisture stability and excellent product stability. have.

Therefore, according to the present invention, excellent moisturizing properties and excellent stability of the product can simultaneously produce a base make-up makeup without a basic makeup by having both a skincare function and a base make-up function as a moisturizing combination. There is an effect of obtaining a cosmetic composition for make-up of silicone water-in-oil emulsion formulations with improved properties.
