Document Type and Number:
WIPO Patent Application WO/2022/249985
Kind Code:
A1
Abstract:
An oil gelling agent that is a copolymer comprising, as constituting units: (a) a hydrophilic (meth)acrylic monomer selected from general formulae (1) and (2) [in formula (1), R1 represents a hydrogen atom or a methyl group, and R2 represents an alkylene group] [in formula (2), R1 represents a hydrogen atom or a methyl group, and R3 represents a group selected from among a hydrogen atom, an alkyl group and a hydroxyalkyl group]; (b) a hydrophobic (meth)acrylic monomer represented by general formula (3) [in formula (3), R1 represents a hydrogen atom or a methyl group, and R4 represents a straight-chain alkyl group having 1-24 carbon atoms]; and (c) a crosslinker monomer having two or more radical polymerizable functional groups per molecule. The ratio by mass of (b) to (a) [(b)/(a)] is 0.8-4.0 and the content of monomer (c) in all monomers is 0.05-5 mass%. This oil gelling agent forms a gel having high temperature stability.
