Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water-in-oil type emulsion cosmetic which has no stickiness, gives a refreshing feel, and is excellent in emulsion stability.

[0002]

2. Description of the Related Art Conventionally used water-in-oil type emulsion cosmetics prevent water evaporation by forming an oil film on the skin surface, and are characterized by excellent water repellency and little makeup loss. Have However, on the other hand, there is also a problem that the oily component and the sticky feeling when applied are strong depending on the contained oily component.

Therefore, in order to solve these problems, silicone oil is used as an oily component. This silicone oil is known as an oily component excellent in lubricity and water repellency, and can impart a refreshing feeling of use and improve oil resistance. However, when a large amount of silicone oil is used as an oil component, it becomes difficult to uniformly emulsify, the emulsion stability of the product is lowered, and problems such as separation of an aqueous phase from an oil phase and exudation of oil occur.

Therefore, in order to improve the stability of the emulsion composition containing silicone oil, an emulsion cosmetic containing a clay mineral and a polyoxyalkylene-modified silicone (JP-A-61-212321), Emulsified cosmetics containing amino acids, oxyacids, etc., polyoxyalkylene-modified silicones, polyhydric alcohols, and silicone oils have been proposed (JP-A-62-215510). However, none of the emulsified cosmetics is sufficiently satisfactory in terms of emulsion stability, particularly stability over time.

[0005]

SUMMARY OF THE INVENTION It is therefore an object of the present invention to solve the above problems and provide a water-in-oil type emulsion cosmetic having excellent emulsion stability and good feeling in use.

[0006]

Means for Solving the Problems As a result of intensive studies for achieving the above object, the present inventors have found that a silicone oil can be obtained by adding an amine derivative having a specific structure or an acid addition salt thereof together with a silicone oil and a silicone-based emulsifier. It was found that even if a large amount of is blended, a water-in-oil emulsion cosmetic having excellent emulsion stability and a refreshing feeling of use can be obtained,
The present invention has been completed.
