METHOD FOR PREPARING HIGH-WATER-CONTENT EMULSION GEL USING OIL GEL-FORMING AGENT

摘要

[Problem] To provide a stable high-water-content W/O-type emulsion gel. [Solution] A W/O-type emulsion gel which comprises a gel-forming agent comprising a compound represented by formula (1) or (2) (wherein R1 and R3 independently represent a linear or branched alkyl group having 1 to 20 carbon atoms, a cyclic alkyl group having 3 to 20 carbon atoms, or a linear or branched alkenyl group having 2 to 20 carbon atoms; n represents an integer of 0 or 1 to 4; R2 represents a hydrogen atom, a linear or branched alkyl group having 1 to 10 carbon atoms, or an aryl group which may have a substituent; and R4 and R5 independently represent a hydroxy group), a surfactant, and a solvent mixture comprising a hydrophobic organic solvent and water, wherein the gel-forming agent is contained in an amount of 0.1 to 20% by mass relative to the mass of the solvent mixture.
