Technical Field

The present invention relates to a moisture-releasing stick cosmetic, and more particularly, to a moisture-releasing stick cosmetic which can directly supply a large amount of moisture to give a moist feeling and a cool feeling, has a hardness suitable for stick cosmetics, has excellent formulation stability, is excellent in spreadability, is excellent in storage stability, and is also excellent in color feeling, and a method for producing the same.

Background

The following description is merely provided for background information related to the present invention and does not constitute prior art.

The stick-type cosmetic has an advantage of being advantageous in use and storage because the formulation is a solid phase as compared with general cosmetics. Due to the advantages of such stick-type cosmetics, attempts have been made in recent years to produce cosmetics in stick form for various uses.

Since the stick cosmetic is applied directly to the skin without using hands, the stick cosmetic needs to have spreadability at the time of application and appropriate hardness for maintaining the stick shape.

In addition, when moisture is contained in a cosmetic and the moisture is directly supplied to the skin, there is an advantage that sufficient moisture supply can be easily achieved and a cool feeling can be imparted during makeup, and thus attempts have been made to contain moisture in a stick-shaped cosmetic. However, when water is contained in a stick cosmetic, there is a problem that the stability of the stick formulation is remarkably lowered.

In order to solve this problem, korean laid-open patent No. 1999 0069366 provides a lipstick composition in which 5.0 to 20.0 wt% of a polar ester selected from the group consisting of diglyceryl isostearate, diglyceryl diisostearate and diglyceryl triisostearate forms a gel network with a hydrophilic humectant to give a lipstick having a suitable hardness, but has a limitation in that moisture cannot be directly supplied.

Further, korean patent laid-open No. 10-2016-.

In particular, in the case of lip cosmetics, there is also described a water-dispersible lip cosmetic composition containing sodium polyacrylate starch which can be applied to an existing lipstick after it is applied thereto in order to supply moisture. However, since the conventional water-dispersible lip cosmetic composition other than lipstick is used, there is a problem that it is inconvenient to use, and a stick-type cosmetic which can release water by using only lipstick is actually required.
