Moisturizing base material containing lipid peptide compound

A premix for a moisturizing base material, the premix comprising:

• a lipid peptide compound including at least one of compounds of Formulae (1) to (3) below or pharmaceutically usable salts thereof;
• a surfactant;
• 1,2-alkanediol or glycerin;
• and
• at least one fatty acid.
• (wherein R1 is a C9-23 aliphatic group;
• R2 is a hydrogen atom or a C1-4 alkyl group that optionally has a branched chain having a carbon atom number of 1 or 2;
• R3 is a —(CH2)n—X group;
• n is a number of 1 to 4;
• and X is amino group, guanidino group, —CONH2 group, or a 5-membered cyclic group optionally having 1 to 3 nitrogen atoms, a 6-membered cyclic group optionally having 1 to 3 nitrogen atoms or a condensed heterocyclic group constituted by a 5-membered cyclic group and a 6-membered cyclic group which optionally have 1 to 3 nitrogen atoms.)
• (wherein R4 is a C9-23 aliphatic group;
• R5 to R7 are each independently a hydrogen atom, a C1-4 alkyl group that optionally has a branched chain having a carbon atom number of 1 or 2, or —(CH2)n—X group;
• n is a number of 1 to 4;
• and X is amino group, guanidino group, —CONH2 group, or a 5-membered cyclic group optionally having 1 to 3 nitrogen atoms, a 6-membered cyclic group optionally having 1 to 3 nitrogen atoms or a condensed heterocyclic group constituted by a 5-membered cyclic group and a 6-membered cyclic group which optionally have 1 to 3 nitrogen atoms.)
• (wherein R8 is a C9-23 aliphatic group;
• R9 to R12 are each independently a hydrogen atom, a C1-4 alkyl group that optionally has a branched chain having a carbon atom number of 1 or 2, or —(CH2)n—X group;
• n is a number of 1 to 4;
• and X is amino group, guanidino group, —CONH2 group, or a 5-membered cyclic group optionally having 1 to 3 nitrogen atoms, a 6-membered cyclic group optionally having 1 to 3 nitrogen atoms or a condensed heterocyclic group constituted by a 5-membered cyclic group and a 6-membered cyclic group which optionally have 1 to 3 nitrogen atoms.)
