To obtain the subject composition having excellent stability at a high temperature near a specific temperature such as bodily temperature and useful for pharmaceuticals, cosmetics, foods, etc., by including a benzyloxycarbonylamino acid derivative.
A compound expressed by the formula (R1 is benzyl; R2 is a 6-22C alkylamino, a 6-22C alkenylcarbonylphenoxy, etc.; R3 is a 1-4C alkyl; (n) is 1-4) is produced by benzyloxycarbonylating the amino group of an amino acid, etc., with benzyl chloroformate, etc., and condensing the product to a corresponding alkylcarbonylphenol, etc., using an esterifying agent as a catalyst. The objective composition can be produced by using the compound as a component in an amount of 0.1-100 pts.wt., preferably 0.5-90 pts.wt. based on 1 pt.wt. of an oily component.
