## Background
TECHNICAL FIELD
The present invention relates to a novel organopolysiloxane having a specified structure, as well as a cosmetic containing the aforementioned organopolysiloxane.
This application claims priority to and all the advantages of International Patent Application No. PCT/JP2010/072067, filed on Dec. 2, 2010, which claims priority to Japanese Patent Application No. JP 2009-275675, filed on Dec. 3, 2009.
BACKGROUND ART
Conventionally, as volatile components (oil agents) composing a cosmetic, cyclic polysiloxanes such as octamethylcyclotetrasiloxane (hereinafter, referred to as “D4”), decamethylcyclopentasiloxane (hereinafter, referred to as “D5”) and the like have been used. However, while D4 exhibits superior volatility, in the case of storing a cosmetic containing D4 at low temperature, D4 is crystallized, and for this reason, there is a problem in that the sensation during use is remarkably impaired. On the other hand, D5 has no problems in storage stability at low temperature, but the volatility thereof is insufficient, and for this reason, there is a problem in that good sensation during use in a cosmetic containing D5 cannot be obtained, such that feeling to touch is heavy during use, stickiness is exhibited, and a dry feeling occurs on skin or hair to which it is applied, and the like.
Considering the aforementioned problems, WO 01/15658 proposes a cosmetic containing an organopolysiloxane represented by {(CH3)3SiO}3SiCH3 (hereinafter, referred to as “methyltrimethicone”) as a volatile component.
However, while the cosmetic blending the organopolysiloxane described in WO 01/15658 exhibits superior volatility, feeling to the touch during use cannot be sufficiently improved, and in particular, the problem of a dry feeling cannot be sufficiently prevented. In addition, the compounds described in WO 01/15658 have a low miscibility with respect to a UV-ray absorber, and for this reason, a large amount of other oil agents must be blended in the cosmetic in order to dissolve the UV-ray absorber, thereby causing many restrictions with respect to components and compositions of cosmetics. Therefore, further improvements with respect to the aforementioned points are needed.

The obtained mixture was washed with water until the wash liquid exhibited neutrality. The resultant mixture was distilled. Thereby, a large cyclic compound represented by the following formula:




(wherein n=2) was obtained. The boiling point thereof was 125° C./20 torr, and the yield was 17.2 g (yield=35%).

Evaluation 1

Miscibility between 1,2-bis(pentamethyldisiloxy)ethane obtained in Example 1, 1,1,3,3,6,6,8,8-octamethyl-2,7-dioxy-1,3,6,8-tetrasilacyclodecane, dimethylpolysiloxane (SH200-2cs: viscosity=2 cs, manufactured by Dow Corning Toray Co., Ltd.), cyclopentasiloxane, or methyltrimethicone (hereinafter, simply referred to as “silicone component”) and octyl paramethoxycinnamate as a representative UV-ray absorber was evaluated. The silicone component and octyl paramethoxycinnamate were mixed by varying the ratios of the silicone component/octyl paramethoxycinnamate=10/90, 50/50 and 90/10. The mixture was allowed to stand for 6 hours at room temperature. The outer appearance thereof was visually observed. The results are shown in Table 1.

Evaluation 4
Using the antiperspirant of Example 3 and a comparative antiperspirant prepared by replacing the entire amount of 1,2-bis(pentamethyldisiloxy)ethane in the antiperspirant of Example 3 with cyclomethicone, the sensation during use of the cosmetics was evaluated by 20 panelists in view of a property of spreading on skin during use and a property of controlling a dry feeling after application.
The comparison evaluation was carried out on the basis of the following two points:

    (1) whether or not a property of spreading the antiperspirant on the skin during use was good.
    (2) whether or not a dry feeling was felt after application.


“Dry feeling” means that a panelist feels a negative sensation during use such as a dry feeling to the touch (sometimes expressed by “dryness”) a dry sensation or de-sebum sensation on the skin, immediately after application or some time after application. When dry feeling is controlled, a more preferable sensation during use is realized. In the following table, the results of comparison evaluation carried out by 20 panelists are shown.

As shown in Table 4, the antiperspirant of Example 3 was evaluated as having better spreading properties on the skin, compared with the comparative antiperspirant by the most panelists. In addition, the antiperspirant of Example 3 was evaluated as having a more preferable sensation during use such as moisturizingly spreading on the skin without a dry feeling, compared with the comparative antiperspirant.
As described above, it was confirmed that the antiperspirant of Example 3 was remarkably superior to the comparative antiperspirant in view of both a property of spreading during use and a property of controlling a dry feeling after application.
