[PROBLEMS] To provide a method for forming a hydrogel-forming material, a premix, and a hydrogel capable of forming a hydrogel in a simpler method and at a milder temperature condition (room temperature). [MEANS FOR SOLVING PROBLEMS] A lipid peptide type compound comprising at least one of a compound represented by the following formula (1) or a pharmaceutically usable salt thereof, a dispersion phase (A) containing water and a fatty acid salt, Of the dispersed phase (B). (Wherein, R 1 is an aliphatic carbon atoms from 9 to 23, R 2 represents an alkyl group of a hydrogen atom, or carbon atoms carbon atoms which may have a branched chain of atoms 1 or 2 atoms of 1 to 4, R 3 is - (CH 2 ) n -X group, n represents a number of 1 to 4, and X represents an amino group, guanidino group, -CONH 2 group, or a 5-membered ring or 6-membered ring which may have 1 to 3 nitrogen atoms Or a condensed heterocyclic ring composed of a 5-membered ring and a 6-membered ring). |
