Stick-shaped base material containing lipid peptide compound

A solid base material for skin external application, the solid base material comprising:

• at least one surfactant selected from the group consisting of ethylene glycol alkyl ether, phospholipid, polyglycerol fatty acid esters, and polyoxyethylene polyoxypropylene alkyl ether;
• one selected from a 1,2-alkanediol or glycerol;
• at least one fatty acid;
• water;
• and
• a lipid peptide compound including at least one of compounds of Formulae (1) to (3) or pharmaceutically usable salts of the compound:
• where R1 is a C9-23 aliphatic group;
• R2 is a hydrogen atom, or a C1-4 alkyl group that may have a C1 or C2 branched chain;
• and R3 is a —(CH2)n—X group, where n is a number from 1 to 4, and X is amino group, guanidino group, —CONH2 group, or a 5-membered or 6-membered ring that may have 1 to 3 nitrogen atoms or a condensed heterocycle composed of 5-membered and 6-membered rings that may have 1 to 3 nitrogen atoms,
• where R4 is a C9-23 aliphatic group;
• R5 to R7 are each independently a hydrogen atom, a C1-4 alkyl group that may have a C1 or C2 branched chain, or a —(CH2)n—X group, where n is a number from 1 to 4, and X is amino group, guanidino group, —CONH2 group, or a 5-membered or 6-membered ring that may have 1 to 3 nitrogen atoms or a condensed heterocycle composed of 5-membered and 6-membered rings that may have 1 to 3 nitrogen atoms,
• where R8 is a C9-23 aliphatic group;
• R9 to R12 are each independently a hydrogen atom, a C1-4 alkyl group that may have a C1 or C2 branched chain, or a —(CH2)n—X group, where n is a number from 1 to 4, and X is amino group, guanidino group, —CONH2 group, or a 5-membered or 6-membered ring that may have 1 to 3 nitrogen atoms or a condensed heterocycle composed of 5-membered and 6-membered rings that may have 1 to 3 nitrogen atoms.
