Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cosmetic containing a specific organopolysiloxane and a partially crosslinked polyether-modified organopolysiloxane, and provides a good feeling of use such as light spread, non-stickiness, and lack of oiliness. The present invention relates to a cosmetic composition having excellent emollient effect and long-lasting makeup while having good stability over time.

[0002]

2. Description of the Related Art In recent years, silicone oil has been widely used as an oil agent in cosmetics in order to make it fresh and non-sticky and to improve the long-lasting makeup. However, silicone oil has poor compatibility with other common cosmetic oils such as hydrocarbons and ester oils, and has no yield value as a flow property. There was a problem that it was difficult. Therefore, swelling properties are imparted to silicone oil using a partially crosslinked polyether-modified organopolysiloxane polymer, and furthermore, silicic anhydride, hydrophobized silica, and saccharides are blended to improve the feeling in use and stability over time. Attempts have been made (Japanese Unexamined Patent Publication No. 4-272932, Japanese Unexamined Patent Publication No.
0320, JP-A-6-40847, JP-A-6-40
No. 848, etc.).

[0003]

The above-mentioned partially cross-linked polyether-modified organopolysiloxane polymer is excellent in refreshing feeling and long lasting makeup.
Further improvements have been demanded for the improvement of the emollient feeling and the stability over time when a large amount of oil other than silicone oil is used. Therefore, there has been a demand for the development of cosmetics having a better feeling in use and stability over time by using a partially crosslinked polyether-modified organopolysiloxane polymer.

[0004]

Means for Solving the Problems The present inventors have made intensive studies to solve the above-mentioned problems, and as a result, in cosmetics, a specific organopolysiloxane and a partially crosslinked polyether-modified organopolysiloxane polymer It has been found that by containing, while having a good feeling of use such as light stretch, stickiness, lack of oiliness, etc., it is possible to obtain a product with excellent emollient effect, long lasting makeup, and good stability over time. Thus, the present invention has been completed.

That is, the present invention relates to the following components (A) and (B): (A) an organopolysiloxane represented by the following general formula (1):
