Polyglycerol, polyglycerol/fatty acid ester, and processes for producing these |
摘要 |
The present invention relates to a polyglycerol significantly reduced in content of a polyglycerol having a cyclic structure formed by removal of a water molecule from a polyglycerol molecule, and to a fatty acid ester of a polyglycerol having excellent surface activity. 2 mole or more of glycidol and a catalyst are successively added to 1 mole of glycerol for a reaction to obtain a polyglycerol, in which a ratio of [total polyglycerol (1)] to [total polyglycerol (2) having a cyclic structure] is [70% or more]/[30% or less] (the total of both is 100% by weight) in terms of an intensity ratio determined by liquid chromatography/mass spectrometry; and an average polymerization degree "n" is 2 or more. A reaction of a polyglycerol with a fatty acid provides the corresponding a fatty acid ester of the polyglycerol.
