Description

The present invention relates to an oil-dispersed cosmetic composition.

The cosmetic composition is variously formulated into an aqueous dispersion formulation using an aqueous phase part and an oil phase part, an oil dispersion formulation, an emulsion formulation, a solubilization formulation, and the like, and is implemented in various forms such as skin, toner, lotion, and cream. On the other hand, skin, toner, etc. are formed in a thin liquid formulation as light spreadability and skin absorption are important.

Accordingly, the use of oil-dispersed cosmetic compositions in which the oil phase is uniformly dispersed in the water phase in the form of granules is increasing in order to mix the aqueous phase and the oil phase, but to achieve a refreshing feeling of use and excellent skin moisturizing feeling. In particular, when the oil phase is uniformly dispersed in the water phase in the form of granules, it is possible to provide a feeling of moisture, nutrition, and skin gloss by the oil while realizing a refreshing feeling of use, and its utility is high. For example, Korean Patent Application Laid-Open No. 10-2014-0073902 discloses an oil drop cosmetic composition comprising a composition comprising an oil phase part having an oil drop property containing caprylic/capric/succinic triglyceride, have.

However, the conventional oil-dispersion cosmetic composition including the above-mentioned publication patent only considers the temporary oil dispersion effect, but does not sufficiently consider the oil dispersion stably maintained for a long time. In particular, the cosmetic composition is exposed to various environments such as low temperature and high temperature as well as room temperature, and the conventional oil-dispersed cosmetic composition including the above patent mainly considers only stability at room temperature, low temperature environment, high temperature environment or There was a problem that the stability of oil dispersion was not sufficiently considered in an environment where low and high temperatures were repeated.

Accordingly, it is an oil-dispersed cosmetic composition that can provide a feeling of moisture, nutrition, and skin gloss by oil while implementing a refreshing feeling of use. The development of a cosmetic composition that can maintain a dispersed state is required.

Experimental Example 3: Evaluation of moisturizing power

The cosmetic compositions of Examples and Comparative Examples were applied to the skin to evaluate moisturizing power, and the results are shown in Table 11. At this time, the moisturizing power was evaluated by measuring the skin moisture improvement effect using the 'Aramo TS-II (model name)' device of Aram Huvis Co., Ltd.

At this time, in Table 11, the case of 39 or less means insufficient moisture, and about 45 to 55 means that the moisture state is good.

Referring to Table 11, when the cosmetic composition of the present embodiment is applied, it can be seen that the appropriate level of moisture is measured, thereby realizing the skin moisturizing effect.
