Abstract
Disclosed are a fatty acid esters composition of a polyglycerine containing more than 70% of a fatty acid monoester which is defined by a specified analysis method, a process for the preparation thereof, a process for the preparation of a highly-purified fatty acid esters composition of a polyglycerine, and a highly-purified fatty acid esters composition of a polyglycerine having an oxirane oxygen concentration of below 100 ppm which is defined by a specified analysis method. The fatty acid esters compositions of a polyglycerine are useful as additives for a variety of food-stuffs, additives for a variety of thermoplastic resins, and as additives for a variety of cosmetics or detergents.
Claims24
A fatty acid esters composition of a polyglycerine containing more than 70% of a fatty acid monoester represented by general formula [1] described below;
- RCO—[OCH2CH(OH)CH2]n—OH [1]
- wherein R is an alkyl group, an alkenyl group, or a hydroxyl group-substituted alkyl group which have 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.
A highly-purified fatty acid esters composition of a polyglycerine having an oxirane oxygen concentration of below 100 ppm, said oxirane oxygen 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.
