[Problem] To provide, by means of a simple composition, a hydrogel-forming material such that, even after the prepared hydrogel has been solated via shaking, the gel can re-form by standing at room temperature. [Solution] A hydrogel-forming material containing water, monopalmitin, and a lipid–peptide gelling agent comprising at least one substance from among compounds represented by formula (1) and pharmaceutically acceptable salts thereof. (In the formula, R1 represents a C9–23 aliphatic group; R2 represents a hydrogen atom or a C1–4 alkyl group that can have a C1–2 alkyl group as a branched chain; R3 represents a –(CH2)n–X group; n represents an integer from 1 to 4; and X represents an amino group, a guanidino group, a –CONH2 group, a 5- or 6-membered ring group having 1 to 3 nitrogen atoms as atoms within the ring, or a condensed heterocyclic group formed from a 5-membered ring and a 6-membered ring.) |
