(Industrial Application Field) The present invention relates to a gel composition, particularly a gel composition based on silicone oil, which is useful as a non-fluidized cosmetic base material without using a filler such as silica. The present invention relates to a composition. (Prior Art) It is already well known that silicone oil is used as an ingredient in cosmetic and medical pastes, creams, pressed compositions, etc., but silicone oil is also used as an inorganic filler. Gel-like products containing hydrophobic silica fine powder have poor transparency, and when applied to the skin, the silica remains on the surface, impairing the aesthetic appearance. The gel-like materials used in this study were considered unsuitable as base materials for cosmetics and medical products. (Structure of the Invention) The present invention relates to a gel-like composition containing silicone oil as a main ingredient, which can be used for cosmetics and medical products.

That is, the present inventors have conducted various studies on gel compositions based on silicone oil, which is highly transparent and has low toxicity, and is particularly useful for cosmetics and medical products. We discovered that the desired gel-like composition could be easily obtained by adding dextrin fatty acid ester as a dextrin fatty acid ester, and conducted research on the types and amounts of silicone oil and dextrin fatty acid ester to be used. The present invention was completed. The silicone oil as the first component constituting the gel composition of the present invention has the general formula (A)

したところ、均質なゲル状組成物が得られた。A methylphenylpolysiloxane containing at least one phenyl group in one molecule, represented by [Formula], where R is a methyl group, a phenyl group and a is 2 to 3, formula (B) Cyclic dimethylpolysiloxane, where n is an integer of 3 to 6, formula (C) , where Q is a hydrogen atom or a trimethylsilyl group, and m is composed of dimethylpolysiloxane, where m is 1 to 650, and when the component (A) is 20% by weight or less, it can be used as the second component described later. Since the compatibility with the dextrin fatty acid ester decreases and it becomes impossible to obtain a homogeneous composition at room temperature, it is necessary to make this component (A) 20% by weight or more, but this is not the case if it consists only of component (A). Good too. In addition, this silicone oil (A) is an essential component, but if the viscosity at 25°C is lower than 4cS, it becomes necessary to increase the amount added to the dextrin fatty acid ester as the second component. A gel composition with good extensibility cannot be obtained, and if the extensibility is greater than 1000 cS, the resulting gel composition will become sticky, resulting in poor extensibility. However, this preferable range is 100 cS or less, more preferably 50 cS or less. In addition, the dextrin fatty acid ester as the second component constituting this composition formula has, for example, the following structural formula: In the formula, A is a hydrogen atom or an acyl group having 12 to 18 carbon atoms, and 50% or more of the total number of moles of A is an acyl group, and l is 20 to 30. If the silicone oil as one component is 100 parts by weight, if it is less than 2 parts by weight, the gelation of this composition will not proceed, and if it is more than 30 parts by weight, the resulting gel composition will become too hard when used as a cosmetic. However, the preferred range is 5 to 20 parts by weight, since the spreadability on the skin becomes poor. The gel composition of the present invention has the above-mentioned first component and second component.
It can be obtained by uniformly mixing a predetermined amount of the dextrin fatty ester with silicone oil, but this mixing is preferably done at 50 to 100°C. The desired homogeneous gel-like composition can be obtained by uniformly dissolving the composition and then allowing it to cool. Next, examples of the present invention will be given, in which parts are parts by weight, and viscosity is a value measured at 25°C. Example 1 Dextrin fatty acid ester Leopard was added to 100 parts of methylphenyl silicone oil KF56 (trade name manufactured by Shin-Etsu Chemical Co., Ltd.) with a viscosity of 20 cS.
Add 10 parts of KL [trade name manufactured by Chiba Flour Milling Co., Ltd.] and heat at 65℃.
After heating and stirring at 200 rpm for 15 minutes to dissolve the dextrin fatty ester in silicone oil, the heating bath was removed and the mixture was allowed to cool.
A homogeneous gel-like composition was obtained. Example 2 70 parts by weight of the methylphenyl silicone oil KF56 (trade name manufactured by Shin-Etsu Chemical Co., Ltd.) used in Example 1 and cyclic dimethylpolysiloxane (n = 5).
In a mixture with 30 parts of KF995 [trade name manufactured by Shin-Etsu Chemical Co., Ltd.], add dextrin fatty acid ester Leopard.
When 20 parts of KL (supra) was added and treated in the same manner as in Example 1, a homogeneous gel-like composition was obtained.
