In the present invention, a fatty acid or a higher alcohol and the ionic polymer form a complex to exhibit an emulsifying action. This complex is considered to have the same action as the surfactant. In addition, since it is a polymer compound, it is considered that it also has a protective colloidal effect and exhibits the same effect as when a low-molecular surfactant and a polymer compound are used in combination.

Can be contained. As the other oil components, any of solid, paste and liquid forms at normal temperature can be used, and hydrocarbon-based polar and non-polar oils, silicone-based oils and the like can be used.

As the fatty acid, a solid or liquid fatty acid having 6 or more carbon atoms (usually 30 or less) at normal temperature (25 ° C.) can be used, but a liquid fatty acid at normal temperature is preferable. Fatty acids having less than 6 carbon atoms have insufficient lipophilicity, and the complex with the ionic polymer is less likely to be oriented in the oil phase. As fatty acids that are solid at room temperature, palmitic acid, stearic acid, 12-hydroxystearic acid, and the like can be used. In addition, as fatty acids that are liquid at ordinary temperature, linear fatty acids such as caproic acid and caprylic acid; branched fatty acids such as isopalmitic acid and isostearic acid; unsaturated fatty acids such as oleic acid, myristoleic acid, and palmitoleic acid are used. can do.

Higher alcohols having less than 6 carbon atoms have insufficient lipophilicity and the complex with the ionic polymer is less likely to be oriented in the oil phase.

If it is less than 0.1% by weight, a good emulsified composition cannot be obtained. There is no particular upper limit on the amounts of fatty acids and higher alcohols, and they can be blended in consideration of usability and the like.

分子 The molecular weight of the ionic polymer is preferably 1,000 to 15,000,000, more preferably 5,000 to 500,000. An ionic polymer having a weight-average molecular weight of less than 1000 may be absorbed transdermally, and an ionic polymer having a weight-average molecular weight of more than 1500,000 increases the viscosity of the emulsified composition and deteriorates usability in terms of stickiness and sliminess. Become.

The ionic polymer is preferably incorporated in an amount of 0.05 to 10% by weight, more preferably 0.1 to 2% by weight. If the amount is less than 0.05% by weight, the emulsifying power is insufficient.

In the present invention, by using one or more compounds selected from the group consisting of inorganic acid salts, organic acid salts, amino acids and salts thereof, one or more compounds selected from the group consisting of fatty acids and higher alcohols are used. The hydrophobicity of the complex formed by the oil component and the ionic polymer insoluble in the oil component increases. When one or more compounds selected from the group consisting of inorganic acid salts, organic acid salts, amino acids and salts thereof are not added, the resulting water-in-oil emulsion composition is converted to an oil-in-water emulsion composition. Phases are likely to occur and it is difficult to obtain a stable water-in-oil emulsion composition. However, by adding one or more compounds selected from the group consisting of inorganic acid salts, organic acid salts, amino acids and salts thereof, phase inversion is unlikely to occur, and a stable oil can be obtained without using a surfactant. A water-in-water emulsion composition can be obtained.

As an inorganic acid salt, an organic acid salt, an amino acid and a salt thereof, any water-soluble salt can be used without particular limitation.

(4) Inorganic acid salts, organic acid salts, amino acids and salts thereof are preferably added in a total amount of preferably 0.1 to 10% by weight, more preferably 0.5 to 5% by weight of the emulsified composition. If the amount is less than 0.1% by weight, the salting out effect is insufficient. If the amount exceeds 10% by weight, salt precipitation or the like occurs, and the system becomes unstable.

By blending the polyhydric alcohol, a gel is formed at the interface between the water phase and the oil phase or at the oil phase, and the stability of the water-in-oil emulsion composition is improved. As the polyhydric alcohol, trihydric or higher alcohols such as glycerin, sorbitol, diglycerin, and polyglycerin can be used. The polyhydric alcohol is preferably blended in an amount of 1 to 20% by weight, more preferably 3 to 15% by weight of the emulsified composition. If it is less than 1% by weight, no gel-like substance is formed, and if it exceeds 20% by weight, a sticky feeling is obtained.
