Description

  The present invention relates to a cosmetic, and more particularly to a cosmetic comprising a specific organopolysiloxane, having a light and smooth feel during use, and having an excellent dry-feel suppressing effect.

  Conventionally, cyclic polysiloxanes such as octamethylcyclotetrasiloxane (hereinafter referred to as “D4”) have been used as volatile components (oil agents) constituting cosmetics.

  However, since the freezing point of D4 is as high as 17 ° C., cosmetics containing this have poor storage stability because the D4 crystallizes and separates in a low temperature environment (in winter). Furthermore, when manufacturing cosmetics, the manufacturing process was complicated, for example, the process of heating D4 to mix | blend was needed.

  In order to solve this problem, decamethylcyclopentasiloxane (freezing point = −40 ° C., hereinafter referred to as “D5”), which is a cyclic polysiloxane having a low freezing point, is mixed (combined) with D4. It has been practiced to use the mixture as a volatile component of cosmetics.

  However, cosmetics containing cyclic polysiloxanes such as D4 and D5 have a heavy feel during use and feel sticky, and D4 and D5 have a relatively large latent heat of vaporization. There is a problem that dry feel (unpleasant cooling feeling due to volatilization of components) occurs in the skin and hair to which the cosmetic is applied, and thus a good feeling of use cannot be obtained.

To solve such a problem, an organopolysiloxane represented by the general formula: [(CH ₃ ) ₃ SiO] ₃ Si (CH ₃ ) (freezing point = −82.8 ° C., boiling point = 190 ° C., hereinafter referred to as “ Cosmetics containing “M3T”) as a volatile component have been proposed (see, for example, Patent Document 1 below).

However, even the cosmetics described in Patent Document 1 cannot sufficiently reduce the feel during use, and cannot sufficiently suppress dry feel. For this reason, cosmetics are required to further reduce the feel during use and to further suppress dry feel.
Republication gazette related to International Publication Number WO01 / 015658

  The present invention has been made based on the circumstances as described above, and the object of the present invention is to provide a cosmetic that has a light and smooth feel during use and is more effective in suppressing dry feel than conventionally known ones. It is to provide. Another object of the present invention is to provide a cosmetic having excellent storage stability. Another object of the present invention is to provide a cosmetic in which a non-volatile organopolysiloxane is uniformly dissolved and dispersed by a specific volatile component.

  As a result of intensive studies by the present inventors in order to solve the above problems, the branched organopolysiloxane having a specific structure has practically sufficient volatility, and contains this as a volatile component. Thus, the present inventors have found that a cosmetic material that is light and smooth during use, excellent in the effect of suppressing dry feel, and excellent in storage stability can be obtained, and the present invention has been completed based on such knowledge.

That is, the cosmetic of the present invention is characterized by containing an organopolysiloxane represented by the general formula (1): [(CH ₃ ) ₃ SiO] ₄ Si (hereinafter referred to as “M4Q”).

  The cosmetic of the present invention preferably further contains a non-volatile organopolysiloxane. In this case, it is preferable to contain M4Q at a ratio of 1 to 10000 parts by mass with respect to 100 parts by mass of the non-volatile organopolysiloxane.

(1) Since M4Q having a low latent heat of vaporization is contained as a volatile component, it is superior in the effect of suppressing dry feel and more suitable than conventionally known cosmetics (cosmetics containing D4, D5, M3T, etc.). A feeling of use can be obtained.
(2) The touch when used is light and smooth.
(3) Even in a low temperature environment, M4Q does not separate and is excellent in storage stability.
(4) A refreshing feel can be imparted without causing an oily feeling to the skin and hair.

  The cosmetic of the present invention is characterized in that it contains M4Q as a volatile component.

  Since the freezing point of M4Q is as low as −60 ° C., the cosmetic of the present invention containing the same can maintain homogeneity even in a low temperature environment (in winter) without the M4Q crystallizing and separating. Excellent stability. Moreover, M4Q has practically sufficient volatility as a volatile component of cosmetics.

  The latent heat of vaporization of M4Q is much smaller than the latent heat of vaporization of D4 and D5, and is also small compared to the latent heat of vaporization of M3T. For this reason, the cosmetics of this invention containing M4Q can suppress dry feeling reliably, and can obtain a favorable usability | use_condition.

  Further, as apparent from the results of Examples described later, the cosmetic of the present invention containing M4Q is light and smooth when used (for example, when applied).

  The content ratio of M4Q in the cosmetic of the present invention is usually 0.1 to 99.9% by mass, preferably 1 to 90% by mass, and more preferably 1 to 50% by mass. The content ratio of M4Q is determined according to the type and amount of other components used together (for example, different types of organopolysiloxane) and the dosage form of cosmetics.

  As a method for producing M4Q, known methods can be mentioned. For example, it can be obtained by cohydrolyzing tetrachlorosilane (1 mol) and trimethylchlorosilane (4 mol or more).

  The cosmetic of the present invention preferably contains a non-volatile organopolysiloxane (hereinafter also referred to as “non-volatile silicone compound”). By using a non-volatile silicone compound in combination, the effects of M4Q (such as the effect of suppressing dry feel and the effect of making the feel light and smooth during use) become particularly remarkable.

  Since the non-volatile silicone compound is excellent in compatibility with M4Q, it can constitute a homogeneous cosmetic (the cosmetic of the present invention). In addition, since the freezing point of M4Q is low, they are not separated even in a low temperature environment, and the homogeneity is maintained. And when this cosmetic is applied to the surface of the skin or hair, M4Q volatilizes quickly without any dry feel, and forms a highly durable film comprising an active ingredient containing a non-volatile silicone compound. Can do.

[Preparation Example 1]
1800 g of water and 200 g of methanol were charged into the reactor, and the reactor was stirred while cooling with ice. A mixture of 420 g of trimethylchlorosilane and 150 g of tetrachlorosilane was added dropwise to carry out the hydrolysis reaction. After completion of the dropwise addition of the mixture, the mixture was aged for 2 hours. After cooling, the waste acid was separated and removed, washed with water and neutralized. After drying by adding anhydrous sodium sulfate, M4Q was obtained by distillation. The boiling point was 103 to 106 ° C./2 mmHg, and the yield was 290 g (yield 85%).
[Preparation Example 2]
152 g of tetramethoxysilane, 324 g of hexamethyldisiloxane and 64 g of methanol are charged into a reactor, and 10 g of concentrated sulfuric acid is added as a catalyst while stirring the reactor, and 32.4 g of water and 32.4 g of methanol are stirred. The mixture was added dropwise to perform a hydrolysis reaction. After completion of the dropwise addition of the mixture, the mixture was aged for 30 minutes and washed with water to remove the catalyst and methanol. M4Q was obtained by adding anhydrous sodium sulfate and drying, followed by distillation. The yield was 280 g (73% yield).
[Preparation Example 3]
A reactor was charged with 75 g of tetraethoxysilane, 130 g of hexamethyldisiloxane and 90 g of acetic acid. While cooling the reactor with ice, 5 g of concentrated sulfuric acid was added and stirred. After aging for 120 minutes and neutralizing with 50 g of sodium bicarbonate, the neutralized salt was removed by filtration. Subsequently, M4Q was obtained by performing distillation. The yield was 99 g (yield 71%).

As a result of analyzing each of M4Q obtained by Preparation Examples 1 to 3 by gas chromatography, the purity of each was 99%. Further, the structure was confirmed using ²⁹ Si-NMR (3Si at δ5-10 ppm, 1Si at δ-60--70, but TMS standard) and mass spectrum (molecular ion peak 310).
