Silicone polymer, silicone composition, and cosmetic preparation containing the same

FIELD OF THE INVENTION

This invention relates to a silicone polymer which is insoluble in organic solvents because it has a three-dimensional crosslinked structure which swells up relative to fluorosilicone oils, to a paste-like composition formed by making the silicone compounds swell up in silicone oil, and to a cosmetic material.

BACKGROUND OF THE INVENTION

In various fields including that of cosmetic products, silicone oils have long been used as base oils on account of their safety.

In particular, with regard to skin care and make up, low viscosity silicone oils of 100 mm

2

/s are very popular on account of their excellent spreading properties, clean feel and high safety.

However, when for example a paste composition without fluidity is made up with a low viscosity silicone oil as base oil, the addition amount of thickener has to be increased, and consequently it is difficult to obtain a smooth, even composition. Moreover, the low viscosity silicone oil tends to separate and leak from the composition obtained, so stability was low. To solve this problem, organic materials such as dextrin fatty acid esters (Japanese Patent Laid-Open Sho 62-121764, 62-143971, 62-143970, 63-159489), cane sugar fatty acid esters (Japanese Patent Laid-Open Sho 63-235366), trimethylsilyl polyvinyl alcohol or trimethyl silyl oligosaccharides (Japanese Patent Laid-Open Sho 62-240335) and fatty acid ester group-containing cellulose ethers (Japanese Patent Laid-Open Sho 63-260955), or inorganic materials such as organically modified clay minerals (Japanese Patent Laid-Open Sho 62-45656, 62-54759, 63-72779), have been used as thickeners for low viscosity silicone oils.

However, when these organic or inorganic materials were used as thickeners, there was a problem in that the clean feel and high extendibility of the low viscosity silicone oil decline.

In this connection, a method was proposed obtain a uniform paste-like composition by using a specific silicone polymer as a thickener, and treating the low viscosity silicone oil under a shear force (Japanese Patent Laid-Open 2-43263).

However, in the field of cosmetic products, not only oil but also water must be blended with the composition as an essential component. In this case, surfactants are used according to the normal procedure, but it is difficult to disperse the silicone oil and water in a homogeneous, stable state. Also, although the silicone thickener disclosed in the aforesaid Japanese Patent Laid-Open 2-43263 has excellent thickening properties relative to the silicone oil, it does not disperse evenly when water is also blended in the composition. Moreover, some surfactants irritate the skin, and their use is therefore undesirable.

To solve this disadvantage, in Japanese Patent Laid-Open Hei 4-272932, and 5-140320, it was proposed to introduce a polyoxyalkylene group in the molecule of the silicone thickener.

At the same time, to improve the staying powers of the cosmetic material, it has been proposed to blend a silicone oil having excellent water repellence and oil repellence and a high fluorine content with the silicone oil. However, although these oils have a high water repellence and oil repellence, water and oil tend to separate from them in storage. Consequently, it was difficult to obtain a cosmetic material having excellent storage stability, and excellent functional properties when it was used on the skin.

Problems Which This Invention Attempts to Solve

It is therefore an object of this invention to provide a silicone polymer having a fluorine-modified oil with excellent water repellence and oil repellence as base oil, and which swells up relative to these oils, to a homogeneous paste-like composition using this silicone polymer, and to a cosmetic material comprising this composition.

are alkyl groups such as methyl, ethyl, propyl, butyl, pentyl, hexyl, heptyl, octyl, nonyl and decyl; saturated alicyclic hydrocarbons such as cyclopentyl and cyclohexyl; aryl groups such as phenyl and tolyl; and fluorine-substituted alkyl groups such as trifluoropropyl, nonafluorohexyl and heptadecylfluorodecyl, but methyl and trifluoropropyl are particularly to be preferred.

Of the organic groups R

1

, it is required that 11-60 mol % are fluorine-substituted monofunctional hydrocarbon groups. If the proportion is less than 11 mole %, swelling properties in the fluorine-substituted silicone oil which is component (C) become poorer, and if it exceeds 60 mol %, manufacture of the component (A1) is difficult. Preferably, the range is 20-50 mole %.

a is 1.0-2.3, but preferably 1.2-2.1. b is 0.001-1.0, but preferably 0.005-0.5. c is 0.001-1.0, but preferably 0.005-0.5. When a is less than 1.0, the degree of crosslinking is too high, so the polymer cannot contain its own weight or more of penta-3,3,3-trifluoropropyl pentamethyl cyclopentasiloxane, and when it is larger than 2.3, the degree of crosslinking is too low, so it is difficult to form the three-dimensional crosslinked structure. When b is less than 0.001, the hydrophilic properties are low, so it is difficult to form a water-in-oil (W/O) composition, and when it is larger than 1.0, hydrophilic properties are too high so it is again difficult to form a water-in-oil emulsion composition. When c is less than 0.001, the degree of crosslinking is low, so it is difficult to form a three-dimensional crosslinked structure, and when it is larger than 1.0, the degree of crosslinking is too high, so the polymer can no longer contain its own weight or more of penta-3,3,3-trifluoropropyl pentamethyl cyclopentasiloxane.

a+b+c is in the range 1.51-2.6, but preferably 1.8-2.2. f is in the range 2-6, but preferably 3-6. g is 2 and/or 3, and/or 4. At least one unit is selected from ethylene oxide, propylene oxide and butylene oxide, but ethylene oxide or a copolymer of ethylene oxide and propylene oxide is preferred. h is an integer in the range 1-200, but preferably 3-100. Examples of R

6

are hydrogen, methyl, heptyl, propyl, butyl, pentyl, hexyl, heptyl, octyl, nonyl, decyl and acetyl, but hydrogen or methyl are particularly preferred.

This organopolysiloxane may be straight chain, branched or cyclic, but to make the polymerization reaction proceed smoothly, it is preferred that it is straight chain or essentially straight chain, and partly contains branch units.

d is 1.0-2.3, but preferably 1.2-2.1, and e is 0.001-1.0, but preferably 0.005-0.5. When d is less than 1.0, the degree of crosslinking is too high, so the polymer cannot contain its own weight or more of penta-3,3, 3-trifluoropropyl pentamethylcyclopentasiloxane. When it is larger than 2.3, the degree of crosslinking is too low, so it is difficult to form the three-dimensional crosslinked structure. When e is less than 0.001, the degree of crosslinking is too low, so it is difficult to form the three-dimensional crosslinked structure, and when it is larger than 1.0, the degree of crosslinking is too high, so the polymer can no longer contain its own weight or more of penta-3,3,3-trifluoropropyl pentamethylcyclopentasiloxane.

The component. (B2) may be obtained for example using glycerine or trimethyloylpropane as starting material by alkenyl etheration of the terminal groups.

All three polyoxyalkylene terminal groups are alkenyl etherated, but only two may be blocked by alkenyl ether, and and the remaining one left as a hydroxyl group.

If the component (B2) is obtained using glycerine monoallyl ether or trimethyloylpropane monoallyl ether as starting material by adding an alkenyl oxide and performing alkenyl etheration of the terminal groups, a structure is obtained containing two polyoxyalkylene units in the molecule and three terminal alkenyl groups in the molecule.

When j is less than 1.0, the degree of crosslinking is too high, so the polymer can no longer contain its own weight or more of penta-3,3,3-trifluoropropyl pentamethyl cyclopentasiloxane. When it is larger than 2.3, the degree of crosslinking is too low, so it is difficult to form a three-dimensional crosslinked structure.

This organopolysiloxane may be straight chain, branched or cyclic, but it is preferred that it is straight chain or essentially straight chain, and partly comprises a branch unit. It is particularly preferred that it is a fluorine-modified cyclic silicone represented by the formula:

This fluorine-modified silicone oil has a viscosity at 25 degree C. of 200 mm

The silicone polymer of this invention may be obtained by polymerizing the organohydrogen polysiloxanes represented by (A1) and/or (A2); the polyoxy alkylenes represented by (B1) and/or (B2), and/or (B3), and/or the organopolysiloxane represented by (B4). By kneading this silicone polymer with the fluoride-modified silicone oil (C), a paste-like composition can be obtained. Alternatively, a paste-like composition can be obtained by manufacturing a silicone polymer by polymerizing a mixture comprising the organohydrogen polysiloxanes represented by (A1) and/or (A2), the polyoxy alkylenes represented by (B1) and/or (B2), and/or (B3), and/or the organopolysiloxane represented by (Be), and part of the fluorine-modified silicone oil (C), and kneading this silicone polymer with the remainder of the fluoride-modified silicone oil (C).

To obtain the silicone polymer of this invention, the reaction is performed at room temperature or higher temperature (approx. 50-120 degree C.) in the presence of a platinum compound (e.g., platinic chloride, alcohol-modified platinic chloride or platinic acid chloride-vinyl siloxane complex), or a rhodium compound.

When the reaction is performed, it may be in the absence of a solvent or an organic solvent may be used if necessary. Examples of organic solvents are aliphatic alcohols such as methanol, ethanol, 2-propanol and butanol; aromatic hydrocarbons such as benzene, toluene and xylene; aliphatic or alicyclic hydrocarbons such as n-pentane, n-hexane and cyclohexane; halogenated hydrocarbons such as dichloromethane, chloroform and carbon tetrachloride; and ketone-type solvents such as acetone and methyl ketone. However, due to the intended use in cosmetic products, it is preferred to conduct the reaction in the absence of a solvent, or in ethanol or 2-propanol.

The silicone compound of this invention comprises a three-dimensional crosslinked structure which is insoluble in organic solvents, i.e., it is insoluble in organic solvents comprising aliphatic organic solvents such as straight chain or branched pentanes, hexane, decane, dodecane, hexadecane and octadecane; aromatic organic solvents such as benzene, toluene and xylene; alcohol-type organic solvents such as methanol, ethanol, propanol, butanol, hexanol and decanol; halogenated organic solvents such as chloroform and carbon tetrachloride; ketone-type organic solvents such as acetone and methylethyl ketone, and silicone solvents such as low viscosity dimethyl polysiloxane, methylphenyl polysiloxane and cyclic dimethyl polysiloxane.

The silicone polymer of this invention can also contain at least its own weight pentane-3,3,3-trifluoropropyl pentamethylcyclopentasiloxane, and a method of confirming this will be described later.

In the manufacture of the silicone composition of this invention, when the silicone polymer (C) is kneaded with the fluorine-modified silicone oil, this may be accomplished by an ordinary stirrer, but it is preferably performed under a shear force. This is because the silicone polymer has a three-dimensional crosslinked structure insoluble in solvents and the silicone polymer and the component (C) do not blend together homogeneously, so a paste-like composition of smooth appearance must be obtained by supplying sufficient dispersion.

The kneading may be performed for example by a three roller roll mill, two roller mill, side grinder, colloid mill, Gowling homogeniser or Disper, but a three roller roll mill or a D spur are preferred.

The proportion of the silicone composition a) in the cosmetic material of this invention is in the range 0.1-70.0 wt %, but preferably 1.0 to 50.0 wt %. If it is less than 0.1%, the cosmetic material obtained using it does not have good storage stability, and if it exceeds 70.0%, it no longer has a clean feel when spread on the skin.

Solubility of Silicone Polymer, and Swelling Properties of Penta-3,3,3-trifluoropropyl pentamethylcyclopentas

10 wt parts of the polymer obtained were mixed with 90 weight parts of an organic solvent shown in Table 1, and the solubility after stirring for 2 hours was examined. The amount of penta-3,3,3-trifluoropropyl pentamethyl cyclopentasiloxane which could be contained is shown in Table 2.

Herein, the amount of penta-3,3,3-trifluoropropyl pentamethyl cyclopentasiloxane which can be contained was measured by the following method.

Firstly, a fixed amount of the silicone polymer was taken in a vessel, penta-3,3,3-trifluoropropyl pentamethyl cyclopentasiloxane was added, and the mixture left at room temperature without stirring for 10 hours. After leaving, the sample was placed on a 100 mesh net, and it was examined whether or not penta-3,3,3-trifluoropropyl pentamethyl cyclopentasiloxane had separated. The measurement criterion was that the amount of penta-3,3,3-trifluoropropyl pentamethyl cyclopentasiloxane which separated after leaving for five minutes was less than 10%. When the separation amount was less than 10%, confirmation tests were performed by adding more penta-3,3,3-trifluoropropyl pentamethyl cyclopentasiloxane until the separation amount was at least 10%.

From the above results, it is seen that, as the silicone polymers of the comparative examples also have a three-dimensional crosslinked structure, they are insoluble in organic solvents, but they do not have swelling properties relative to fluorine-modified silicone oils having a high fluoroalkyl group content, i.e., a high water repellence and oil repellence. On the other hand, the silicone polymer of this invention is insoluble in organic solvents, and does have excellent swelling properties relative to high fluorine-modified silicone oils.

A semi-transparent paste-like composition having thixotropic properties was obtained. Even after leaving this paste-like composition at 50 degree C. for one month, no separation of the oil component was observed.
