DESCRIPTION

[0001] 1. Technical Field

[0002] The present invention relates to a cosmetic material using silicone-modified wax, specifically carboxyl group-and/or carboxylic acid anhydride-containing polyethylene wax and/or polypropylene wax modified with a silicone. More specifically, the invention is concerned with a cosmetic material in which the wax specified above is incorporated to impart thereto a good spread capability, high possibility of giving a feeling of refreshment to users and strong repellencies to sweat and water. When applied to skin, the present cosmetic material can therefore ensure elasticity, smoothness, emollient effect, natural luster and good keeping qualities.

[0003] 2. Background of the Invention

[0004] Hitherto, cosmetic materials containing liquid unctuous agents, such as paraffin, ester, higher alcohol, glyceride and the like, have been used for the purpose of adding elasticity, smoothness, emollient effect and so on. However, these cosmetic materials have drawbacks of producing a greasy feeling, a tacky feeling and a feeling of being covered with an oil film. So it has also been known to mix silicone oils, such as dimethylpolysiloxane, in the cosmetic materials of the aforementioned compositions with the intention of reducing those greasy, tacky and filmy feels.

[0005] Although silicone oils have good spread capability, high smoothness and strong repellency, they have a disadvantage of being inferior in compatibility with liquid oils of hydrocarbon type. In addition, silicone oils have low surface tension, so they spread quickly and have short residence time. Such being the case, attempts to solidify silicone oils have been made.

[0006] As materials capable of providing silicone oils in a solid state, the compound having a silicone chain to which alkyl groups are introduced (Japanese Patent Laid-Open (hereinafter referred to as “Tokkai”) Hei 2-64115), the compound having a silicone chain to which 21-30C aliphatic alcohol or acid ester groups are introduced (Tokkai Hei 10-500431), the acrylate silicone (Tokkai Hei 2-132141) and so on have been reported. With the compounds having silicone chains to which alkyl groups and long chain fatty acid ester groups are introduced respectively, however, it is hard to smoothly solidify silicone oils themselves. In general, therefore, solidification of those compounds are made in the presence of liquid oil, such as ester oil, triglyceride oil, paraffin oil or so on, because their affinities for waxes are enhanced under such a condition. In the case of the acrylate silicone, on the other hand, the silicone oil by itself can form a solidified matter. However, this solidified matter is resinous and lacking in smoothness suitable for cosmetics. Under these circumstances, solid substances capable of bringing silicone oil characteristics into full play, and that with highly satisfactory smoothness, still haven't been found.

[0007] As a result of our intensive studies of solidified silicone oils suitable for cosmetic materials, it has been found that silicone oil can be made into a smooth solid by mixing with silicone-modified wax containing an ester linkage in a molecule which is produced by reacting carboxyl group- and/or carboxylic anhydride-containing polyethylene and/or polypropylene wax with a silicone compound, preferably a silicone compound containing only one epoxy group in a molecule or a silicone compound containing both only one carbon-carbon double bond and only one epoxy group in a molecule, and then subjecting the resultant reaction product to hydrosilylation reaction with a silicone compound, preferably a silicone compound containing only one silicon-hydrogen bond in a molecule, thereby achieving the invention.

[0008] Therefore, an object of the present invention is to provide a cosmetic material having excellent usability and high * stability over a long term, specifically a cosmetic material which can be spread lightly, easily and smoothly without tackiness when applied to skin and arouse dry, smooth and refreshing feelings in users, and further has not only strong repellency to sweat and water but also properties of imparting elasticity, smoothness, emollient effect and natural luster to skin without impairing skin's moderate transpiration by application thereof.

Disclosure of the Invention

[0009] The present invention is a cosmetic material containing silicone-modified wax as Component (A), characterized in that the silicone-modified wax is wax in which low-molecular-weight polyethylene and/or low-molecular-weight polypropylene is linked to a silicone via an ester linkage.

[0010] The present cosmetic material can be spread lightly and produce a feeling of refreshment when applied to skin. More specifically, it can be spread easily and smoothly without tackiness when applied to skin and arouse dry, smooth and refreshing feelings in users. Further, the present cosmetic material has good long-term stability as well as excellent usability since it has not only strong repellency to sweat and water but also properties of imparting elasticity, smoothness, emollient effect and natural luster to skin without impairing skin's moderate transpiration by application thereof.

Best Mode for Carrying out the Invention

[0011] It is appropriate that the low-molecular-weight, carboxyl group- and/or carboxylic anhydride-containing polyethylene and/or polypropylene used as a starting material of the present silicone-modified wax has a molecular weight of 1,000 to 50,000. In particular, maleic anhydride-grafted polyethylene and polypropylene having an acid value of 10 to 100 KOH mg/g are advantageously used as such a starting material. Although these polyethylene and polypropylene are marketed by, e.g., Mitsui Chemicals and Sanyo Chemical Industries, Ltd. under the trade names of Mitsui Hiwax and Yumex, respectively, there have been no cases of using such high-melting-point silicone wax in cosmetic materials. However, the present invention enables smooth solidification of silicone oils themselves by taking advantage of their high-melting-point characteristics.

[0012] Methods for synthesizing the aforesaid silicone-modified wax used in the invention fall into two broad categories. The methods in the first category involve reaction of carboxyl group- and/or carboxylic anhydride-containing polyethylene (or polypropylene) wax with an epoxy group-containing dimethylsilicone, preferably a dimethylsilicone having an epoxy group at only one end of its chain. Therein, a silicone compound having two or more epoxy groups at both ends or/and in the interior of its molecule may be also used so far as it causes gelling in the reaction product. In carrying out the reaction, solvents may be used or not, and it is appropriate that the reaction temperature be adjusted to 100° C. or higher, especially 140° C. or higher.

[0013] When no solvent is used in the reaction, it is preferable to adjust the reaction temperature so as to be higher than the melting point of the wax used. The reaction may be conducted in the absence or presence of a catalyst. In the case of using a catalyst, tertiary amines, metal soaps, imidazole compounds and so on are suitable as the catalyst. As to the proportion of the silicone compound to the wax in the reaction, it is appropriate that the silicone compound be used in an amount of 0.2 to 5 equivalents, particularly 0.5 to 2 equivalents, in terms of epoxy group when the wax is used in an amount of 1 equivalent in terms of carboxyl group. In respect of reactivity, cyclic epoxy groups are preferred to linear epoxy groups. Although the reaction time depends on the reaction temperature, it usually takes 5 to 10 hours to complete the reaction.

[0014] The methods in the second category involve, as the first step, reaction of a compound containing an epoxy group and a double bond in its molecule, e.g., Celoxide 2,000 (trade name of vinylcyclohexene epoxide produced by DaiCel Chemical Industries, Ltd.), with carboxyl group and/or carboxylic anhydride-containing polyethylene (or polypropylene) wax. Since the compound, such as Celoxide 2,000, can be removed by heating under reduced pressure after the reaction, it is advantageous from the viewpoint of enhancing reaction efficiency to use 1.2 to 5 equivalents of Celoxide 2,000 or the like with respect to 1 equivalent of carboxyl group in the wax. The suitable reaction conditions are the same as in the former case of using an epoxysilicone compound.

[0015] By distilling off Celoxide 2,000 or the like through heating under reduced pressure, double bond-introduced polyethylene (or polypropylene) wax can be obtained. It is appropriate that addition reaction between this wax and a Si—H bond-containing silicone be carried out at the melting temperature of the wax or-higher when conducted in the absence of a solvent. When the addition reaction is conducted in the presence of a solvent, on the other hand, the suitable reaction temperature is in the range of 80° C. to 140° C. As a catalyst for the addition reaction, precious metal catalysts, such as chloroplatinic acid, can be used. Therein, it is appropriate that the silicone compound be used in an amount of 0.1 to 5 equivalnets, particularly 0.2 to 1 equivalent, in terms of Si—H group when the wax is present in an amount of one equivalent in terms of double bond. In the case of using a solvent, the intended silicone-modified wax can be obtained by distilling off the solvent through heating under reduced pressure.

[0016] The present silicone compound can be used for a wide variety of purposes. Specifically, it is highly suitable as an ingredient in every kind of cosmetic material externally applied to skin or hair, including skin-care cosmetics, makeup cosmetics, hair-care cosmetics, antiperspirant cosmetics, UV protective cosmetics and so on. In such cosmetics, it is possible to mix the silicone-modified wax of Component (A) in a proportion of 0.1 to 95 weight % to total cosmetic material. In a special case of solid-state or stick-shaped cosmetic materials wherein powdery ingredients account for at most 25 % of total formulation, the suitable proportion of the present silicone-modified wax compounded is from 5 to 95 weight % to total cosmetic material. In another case of solid cosmetics wherein powdery ingredients are contained in a proportion of at least 80 weight % to total formulation, it is appropriate to mix the present silicone-modified wax in a proportion of 0.1 to 10 weight % to total cosmetic material.

[0017] The present cosmetic materials can further contain as Component (B) one or more kinds of unctuous agents depending on the desired purposes thereof.

Synthesis Example 1

[0061] In a flask were placed 280 g of maleic anhydride-modified low-molecular-weight polyethylene wax (Mitsui Hiwax 3202A, trade name, a product of Mitsui Chemical) having a molecular weight of 4,400, an acid value of 20, a carboxyl equivalent of 2,800 and a melting point of 102° C. (wherein 0.1 mole of carboxyl groups were contained), 37.2 g (0.3 mole) of vinylcyclohexene epoxide and 640 g of xylene. Reaction was run for 5 hours in the flask while refluxing the xylene. After the conclusion of the reaction, both xylene and excess vinylcyclohexene epoxide were distilled off by heating under reduced pressure, and polyethylene wax having a vinyl group in individual molecules thereof was obtained. Then, 200 g of the thus obtained polyethylene wax was weighed out, mixed with 200 g of one-end hydrogensiloxane having the following average structural formula, 800 g of xylene and 0.2 g of a 3 % isopropanol solution of chloroplatinic acid in a flask, and therein the reactants underwent 5-hour reaction under reflux of xylene.

[0062] By heating and distilling off the solvent under reduced pressure, silicone-modified Wax (I) having a melting point of 98° C. was obtained.

Synthesis Example 2

[0063] In a flask were placed 280 g of maleic anhydride-modified low-molecular-weight polypropylene wax (Mitsui Hiwax NP0555A, trade name, a product of Mitsui Chemical) having a molecular weight of 17,400, an acid value of 47, a carboxyl equivalent of 1,190 and a melting point of 140° C. (wherein 0.1 mole of carboxyl groups were contained), 119 g (0.047 mole in terms of epoxy group) of silicone having an epoxy group at one molecular-chain end and an average structural formula illustrated below (epoxy equivalent: 2,500), 0.5 g of dimethylethanolamine as a catalyst and 400 g of xylene as a solvent.

[0064] And in the flask, reaction was run for 5 hours while refluxing the xylene. By heating and distilling off the solvent under reduced pressure, silicone-modified Wax (II) having a melting point of 127° C. was obtained.
