A method for producing a polyvalent alcohol ester compound, characterized in that a polyvalent alcohol compound and a carboxylic acid compound are allowed to react in the presence of an acidic solid catalyst swollen with the polyvalent alcohol compound or the carboxylic acid compound without using a solvent to selectively produce a monocarboxylic acid ester or a polycarboxylic acid ester of a polyvalent alcohol. In this manner, a mono-fatty acid ester and a poly-fatty acid ester (e.g., di-fatty acid ester) of a polyvalent alcohol can be selectively and effectively produced from a polyvalent alcohol compound and a fatty acid compound.

A composition having a recycle content value is obtained by reacting a recycle content feedstock to make a recycle content glycol ester by deducting from a recycle inventory a recycle content value applied to a glycol ester composition. At least a portion of the recycle content value in the feedstock or in an allotment obtained by a glycol ester manufacturer has its origin in recycled waste and/or pyrolysis of recycled waste and/or in thermal steam cracking of recycle content pyoil.

which are useful in maintaining, enhancing, and expanding of hematopoietic stem cells.

A method for producing diglycerides is provided. The method includes combining (i) an oil comprising at least one polyunsaturated fatty acid in the form of ethyl esters, free fatty acids, and/or combinations thereof, (ii) lipase, and (iii) glycerol in water to produce diglycerides with a high level of purity. Highly pure diglycerides obtained according to the method are also provided.
