An impact resistance enhancing agent for a polylactic acid-based resin, containing a polyglycerol fatty acid ester made from a fatty acid containing at least one member selected from the group consisting of caprylic acid, capric acid, lauric acid, myristic acid, palmitic acid, stearic acid, and oleic acid, in an amount of 80% by mass or more of the constituting fatty acids, and a polyglycerol having an average degree of polymerization of from 2 to 40. The polylactic acid-based resin composition containing an impact resistance enhancing agent for a polylactic acid-based resin of the present invention has excellent impact resistance properties, so that the resin composition can be suitably used in, for example, agricultural materials, food wrapping materials, and other wrapping materials, and the like.

Agent for imparting impact resistance to polylactic acid resin

A polyglycerol fatty acid ester formed by esterifying a polyglycerol and a fatty acid, wherein the polyglycerol has a hydroxyl value of 1200 or less and primary hydroxyl groups in an amount of 50% or more of the total hydroxyl groups, and an emulsified or solubilized composition, foodstuff, and cosmetics, each containing the polyglycerol fatty acid ester.
