Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a pasty oil composition and a cosmetic composition containing the same, and more specifically, a silicone polymer having a specific structure and a liquid oil are kneaded at a specific ratio under shearing force. The present invention relates to a paste-like oil composition obtained by treatment, and a cosmetic containing the paste-like oil composition.

[0002]

2. Description of the Related Art Liquid oils such as hydrocarbon oils, ester oils, triglyceride oils, higher fatty acid oils, and higher alcohol oils are used in the form of pastes or gels in the form of pastes or gels, which are conventionally used in the fields of medicine and cosmetics. It is more widely practiced. To make these liquid oils into a paste or gel,
Conventionally, metal soap, sucrose fatty acid ester, organic bentonite, dextrin fatty acid ester and the like have been used alone or in combination.

[0003]

However, since metal soap has poor solubility in liquid oil and requires a high temperature of about 100 ° C. to dissolve it, it affects other mixed oil agents, pigments, etc. and deteriorates in quality. In addition, the paste-like or gel-like composition obtained here is prone to change over time such as cracking, oil bleeding, or sweating, and moreover, there are many unsatisfactory points regarding gloss and elongation. . The sucrose fatty acid ester has a problem in that it has poor thickening and gelling properties for liquid oil, and the obtained paste-like or gel-like composition does not have good transparency and lacks stability at low temperatures. Further, the dextrin fatty acid ester is inferior in stability because the gel formed is hard, lacks thixotropic properties, and causes problems such as oil separation over time.

By the way, in the fields of medical treatment and cosmetics, in addition to oil, water is often added as a necessary component in the prepared composition. In such a case, it is difficult to disperse the oil and water in a uniform and stable state without using a surfactant according to a conventional method. However, many surfactants are irritating to the skin, so it is not preferable to use a large amount of them.

The present invention solves the problems when the above-mentioned conventional metal soap, sucrose fatty acid ester, organic bentonite, dextrin fatty acid ester and the like are used as a thickener and has excellent physical properties. An object of the present invention is to provide a paste-like oil composition capable of stably and uniformly dispersing water without using a surfactant, and a cosmetic containing the paste-like oil composition.

[0006]

Means for Solving the Problems The present inventor has conducted diligent research in view of the above circumstances, and as a result, a silicone polymer having a specific structure and a hydrocarbon oil, an ester oil, a triglyceride oil,

It was found that a paste-like oil composition having thixotropy and capable of stably and uniformly dispersing water can be obtained, and a cosmetic containing this paste-like oil composition has good temperature stability and is used. The present invention has been completed by finding that it has excellent properties. Taking advantage of the fact that a silicone polymer having a specific structure has the property of swelling with low-viscosity silicone oil, the low-viscosity silicone oil can be blended with the low-viscosity silicone oil to form a paste or grease. Has been proposed (Japanese Patent Laid-Open No. 4-27293).

In the present invention, a is 1.0 to 2.5, preferably 1.0 to 2.0. When a is less than 1.0, the obtained polymer does not swell sufficiently in liquid oil, and when it is greater than 2.5, the obtained polymer is kneaded with liquid oil under shearing force. Water cannot be sufficiently dispersed in the pasty oil composition.

B is 0.001 to 1.0, preferably 0.005 to 1.0. If b is less than 0.001, water cannot be sufficiently dispersed in the pasty oil composition prepared by kneading the obtained polymer with liquid oil under shearing force, and if b is more than 1.0. The obtained polymer does not swell sufficiently in liquid oil.

C is 0.001 to 1.0, preferably 0.005 to 1.0. When c is less than 0.001, it becomes difficult to form a three-dimensional structure in the polymer obtained by addition polymerization, and the viscosity of the liquid oil is poor. On the other hand, when it is larger than 1.0, the cross-linking density of the three-dimensional structure formed by addition polymerization becomes too high, and the liquid oil cannot be stably held.

D is 1.0 to 3.0, preferably 1.0 to 2.5. When d is less than 1.0, the crosslink density of the three-dimensional structure formed by addition polymerization becomes too high, and a polymer that can stably hold the liquid oil cannot be obtained. On the other hand, when it is more than 3.0, the formation of the three-dimensional structure in the polymer obtained by the addition polymerization becomes insufficient and the viscosity increase of the liquid oil becomes poor.

Further, e is 0.001 to 1.5,
It is preferably 0.005 to 1.0. e is 0.001
If it is smaller, it becomes difficult to form a three-dimensional structure in the intended polymer, and the viscosity of the liquid oil is poor, and if it is larger than 1.5, it is formed by addition polymerization.
The cross-linking density of the dimensional structure becomes too high, and a polymer that can stably hold the liquid oil cannot be obtained.

F and p are 2 to 200, preferably 5 to 100. g and q are 0 to 200,
It is preferably 0 to 100. Further, in order to sufficiently disperse water in the pasty oil composition obtained by kneading the obtained polymer with liquid oil under shearing force, f / g ≧ 1
And / or p / q ≧ 1 is desirable.

J is 1.0 to 3.0, preferably 1.0 to 2.5. When j is less than 1.0, the swelling property of the obtained polymer to liquid oil cannot be sufficiently obtained,
When it is more than 3.0, it becomes difficult to form a three-dimensional structure obtained by addition polymerization, and the viscosity of the liquid oil is poor.

The value of k is 0.001 to 1.5, preferably 0.005 to 1.0. When k is less than 0.001, it becomes difficult to form a three-dimensional structure in the polymer obtained by addition polymerization, and the viscosity increase of the liquid oil is poor. On the other hand, when it is larger than 1.5, the cross-linking density of the three-dimensional structure formed by addition polymerization becomes too high, and the obtained polymer cannot stably hold the liquid oil. m and n are from 2 to 6, but m is from 3 to 3 especially in the case of reacting with the organohydrogenpolysiloxane of the general formula (2).
6 is preferable.

The addition polymerization of the organohydrogenpolysiloxane of the general formulas (1) and (2) with the polyoxyalkylene of the general formula (A) and / or the organopolysiloxane of the general formula (B) is carried out by using a platinum compound. (For example, chloroplatinic acid, alcohol-modified chloroplatinic acid, chloroplatinic acid-vinylsiloxane complex, etc.), or in the presence of a rhodium compound,
The reaction may be performed at room temperature or under heating (about 50 to 150 ° C).

Examples of the organic solvent include aliphatic alcohols such as methanol, ethanol, 2-propanol and butanol; aromatic hydrocarbons such as benzene, toluene and xylene; aliphatic or fats such as n-pentane, n-hexane and cyclohexane. Cyclic hydrocarbons include halogenated hydrocarbons such as dichloromethane, chloroform, carbon tetrachloride, trichloroethane, trichloroethylene, fluorinated chlorohydrocarbons and the like, but ethanol is particularly preferable from the viewpoint of use for medical and cosmetics.

The silicone polymer used in the present invention can be obtained, for example, by addition-polymerizing the organohydrogenpolysiloxane represented by the general formula (2) and the polyoxyalkylene dialkenyl ether represented by the general formula (A). . The organohydrogenpolysiloxane of the general formula (2) is synthesized by the following method.

In addition, the desired silicone polymer can also be obtained by subjecting the organohydrogenpolysiloxane represented by the general formula (2) to an addition reaction of α-olefin and polyoxyalkylene dialkenyl ether at once. Further, the polymer obtained by reacting the compound represented by the general formula (1) is an organohydrogenpolysiloxane containing no polyoxyalkylene organic group, an α-olefin and an aliphatic monomer at one end. It can be produced by subjecting a polyoxyalkylene having a saturated group to a partial addition reaction and then carrying out addition polymerization with an organovinylpolysiloxane without isolation.

The liquid oil used in the present invention is a hydrocarbon oil such as liquid paraffin oil, squalane or pristane; ester oil such as cetyl isooctanoate, octyldodecyl myristate, isopropyl palmitate, isocetyl stearate or octyldodecyl oleate. Triglyceride oils such as glyceryl trioctanoate and glyceryl triisostearate; higher fatty acid oils such as isostearic acid, oleic acid, hexanoic acid and heptanoic acid; higher alcohol oils such as isostearyl alcohol and oleyl alcohol. These may be used alone or as a mixture of two or more.

In the present invention, the above silicone polymer is used in an amount of 10 to 1,000 per 100 parts by weight of the polymer.
By kneading with the above-mentioned liquid oil in an amount of 20 parts by weight, preferably 20 to 500 parts by weight under a shearing force, a paste-like uniform composition is obtained. In this case, if the amount of the liquid oil used is less than 10 parts by weight, the paste will not be formed, and if it exceeds 1,000 parts by weight, sufficient thickening cannot be obtained, so that a good paste will be obtained. I won't.

The kneading treatment under shearing force is indispensable for obtaining a paste-like composition having a smooth appearance. If the shearing force is not applied or is insufficient, the swelling of the silicone polymer with the liquid oil is insufficient and the two components are present without being mixed with each other, so that the composition obtained is non-uniform and swelling is not observed in the composition. Since a sufficient amount of the silicone polymer remains, the composition does not have smooth feel and appearance.
The kneading treatment performed under shearing force can be performed with, for example, a three-roll mill, a two-roll mill, a sand grinder, a colloid mill, a Gaulin homogenizer, or the like,
A method using a three-roll mill is particularly preferable.

The silicone polymer having a good swelling property with respect to liquid oil was obtained by subjecting it to kneading treatment with liquid oil under shearing force to obtain a paste-like uniform composition. The pasty oil composition can stably disperse powders and pigments having a specific gravity different from that of liquid oil without settling, and can easily disperse water without using a surfactant. Since it is possible, it can be used as a compounding base for drugs, cosmetics (including quasi drugs), and the like.

When the paste-like oil composition is blended with cosmetics, the blending amount is not particularly limited, but is preferably 0.01 to 90% by weight, more preferably 0.1 to 60% by weight.
%. In the present invention, since a paste-like oil composition can be prepared from the above-mentioned general liquid oil, when applied to cosmetics, the degree of freedom of feel, sensory properties, etc. is limited as in the case of using silicone oil. It is easy to proceed with prescription development because it has a wider range.
