A hydrogel-forming material, a premix, and a method for forming a hydrogel through a simple process at room temperature. The material including: a disperse phase (A) including a lipid peptide-based gelator including at least one of a compound of Formula (1) or pharmaceutically usable salt thereof, water, and a fatty acid salt; and a phase (B) that includes a water-soluble acidic polymer: n n n n n n n n n n (where R 1 is a C 9-23 aliphatic group, R 2 is a hydrogen atom or a C 1-4 alkyl group that optionally has a C 1-2 branched chain, R 3 is a —(CH 2 ) n —X group, n is a number of 1 to 4, X is an amino group, a guanidino group, a —CONH 2 group, a 5-membered ring optionally containing 1 to 3 nitrogen atom(s), a 6-membered ring optionally containing 1 to 3 nitrogen atom(s), or a condensed heterocycle that contains a 5-membered ring and a 6-membered ring optionally containing 1 to 3 nitrogen atom(s)). |
