  • MIXTURES OF EPOXIDIZED FATTY ACID ESTERS
    Publication number: 20160060426
    Abstract: A mixture (1) can be prepared in a controlled manner and used as a plasticizer, the mixture contains an epoxidized fatty acid ester A; and a compound B containing a fatty acid chain and having no functional group including a multiple bond in the fatty acid chain. The proportion by mass of compound B is smaller in said mixture (1) than a proportion of compound B in a mixture (2) of compounds containing a fatty acid chain from which the mixture (1) comprising epoxidized fatty acid ester A has been prepared.
