DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a powder cosmetic containing a polyglycerin-modified silicone compound having polyglycerin as a hydrophilic group.

[0002]

2. Description of the Related Art Silicone oils are used in a wide range of fields, including cosmetics, because of their excellent extensibility, freshness and high safety.

[0003]

However, when silicone oil is blended into cosmetics, there is also a problem that the skin does not fit well, lacks a moist feeling, and is negatively functional such as squeaking. Therefore, while having good organoleptic properties such as silicone oil's spreadability and refreshing feeling, the development of a material that has a high moist feeling, excellent adhesion to the skin, and a long-lasting makeup, and a cosmetic that incorporates it, has been developed. Was desired.

[0004]

Means for Solving the Problems In view of the above circumstances, as a result of diligent research, the use of a polyglycerin-modified silicone compound has good adhesion to the skin, excellent usability such as moistness, and a long lasting makeup. It has been found that a very good powder cosmetic can be obtained, and the present invention has been completed.

That is, the present invention relates to a powder cosmetic containing a polyglycerin-modified silicone compound represented by the following general formula (1).
