[Solution] A cosmetic base material is formed from an acylpeptide aliphatic acid amide-amine salt in which a portion or all of an acylpeptide acidic functional group in which a substituent represented by general formula (I) is bound to a peptide active amino group is neutralized in an aliphatic acid amide-amine represented by general formula (II). (In formula (I), R1 represents -CH2CH2-, -CH=CH-, or -C6H4-.) (In formula (II), R2 represents a C11-25 saturated or unsaturated chain hydrocarbon or a C11-25 saturated or unsaturated cyclic hydrocarbon, R3 represents a C1-3 alkylene group, and R4 and R5 each represent a C1-3 alkyl group.) A cosmetic is formed by containing said cosmetic base material.
