Abstract:
A resin composition which comprises:A. a thermoplastic resin, and, B-1. a fatty acid esters composition of a polyglycerine containing more than 70% of a fatty acid monoester represented by the general formula (1) described below: RCOâ€”[OCH2CH(OH)CH2]nâ€”OHâ€ƒâ€ƒ(1) wherein R is an alkyl group, an alkenyl group, or a hydroxyl group-substituted alkyl group which has a carbon number ranging from 6 to 21, and n is an integer of at least 4, based on a peak area ratio detected using an ultraviolet ray absorption detector in a high performance liquid chromatographic analysis method; or B-2. a highly-purified fatty acid esters composition of a polyglycerine having an oxirane oxygen concentration of below 100 ppm, said oxirane concentration is defined by the titration method defined in Cd. 9-57 of Journal of American Oil Chemists' Society, or having a ratio of below 0.01%, said ratio is a peak area value of a chemical shift between 2.7 ppm and 2.8 ppm assigned by methylene proton derived from an oxirane group with respect to a peak area value of a chemical shift between 3.4 ppm and 4.4 ppm assigned by methylene proton and methine proton derived from a polyglycerine with a proton NMR.
