Abstract:
1. A method for producing an oily gel composition comprising mixing components (A), (B), and (C): (A) 4 to 60% by weight of a sphingosine of formula (1): wherein R Y represents a methylene group, a methine group, or an oxygen atom; each of X each of R each R independently represents a hydrogen atom or an amidino group or represent a linear or branched, saturated or unsaturated hydrocarbon group having a total of 1 to 8 carbon atoms which optionally have a substituent selected from the group consisting of a hydroxyl group, a hydroxyalkoxy group, an alkoxy group, and an acetoxy group; a represents a number of 2 or 3; and a bond represented by a broken line and a solid line indicates a saturated bond or an unsaturated bond; (B) 0.5 to 10% by weight of a water-soluble anionic polymer having a carboxyl group; and (C) 30 to 95.5% by weight of an oil in a liquid state at 25° C. selected from the group consisting of a hydrocarbon oil, an ester oil, and an ether oil to form a mixture; and heating the mixture to a temperature equal to or more than a melting point of the component (A) to neutralize the component (B) with the component (A) to form a salt, the heated mixture containing no more than 0.5%, including 0%, by weight of water, wherein component (C) is present in a continuous oil phase.
