According to the present invention, a process is provided for producing an acyl group-containing composition that includes a step of reacting a long chain N-acyl acidic amino acid anhydride with one or more compounds which have, per molecule, m functional groups of one kind or more selected from the group consisting of hydroxyl, amino and thiol groups in an aqueous solvent and/or a mixed solvent of water and an organic solvent (reaction step). The process makes it possible to produce an acyl group-containing composition that is free from coloration under moderate conditions.
根据本发明,提供了一种生产含酰基组合物的工艺,该工艺包括以下步骤:将长链 N-酰基酸性氨基酸酐与一种或多种化合物在水性溶剂和/或水与有机溶剂的混合溶剂中进行反应(反应步骤),这些化合物每个分子具有 m 种官能团,这些官能团选自羟基、氨基和硫醇基组成的组中的一种或多种。该工艺可以生产出在中等条件下不着色的含酰基组合物。
