Abstract:
An oily material composition which comprises, as effective components, both an alkyl or alkenyl ester of an N-long chain acyl neutral amino acid represented by the following formula (1) and a sterol ester of an N-long chain acyl neutral amino acid represented by the following formula (2): where, in the formulae (1) and (2), R1s each independently represent a branched-chain or straight-chain alkyl or alkenyl group having 5-21 carbon atoms; in the formulae (1) and (2), R2s each independently represent a hydrogen atom or an alkyl group having 1-3 carbon atom(s); in the formulae (1) and (2), R3s each independently represent a hydrogen atom, a methyl group, an ethyl group, a branched-chain or straight-chain alkyl group having 3-4 carbon(s), a hydroxymethyl group or a hydroxyethyl group; R4 represents a branched-chain or straight-chain alkyl or alkenyl group having 1-30 carbon atom(s); R5 represents a sterol residue; and, in the formulae (1) and (2), n's each independently represent an integer of 0-2.
