additive 1

Reference substance name:

Soybean oil, epoxidized

EC Number:

232-391-0

EC Name:

Soybean oil, epoxidized

Cas Number:

8013-07-8

Molecular formula:

C57H98O12

IUPAC Name:

Epoxidized Soybean Oil

Test material form:

liquid

Details on test material:

A complex combination of chlorinated fatty acid mtethyl esters that are predominantly C18 (~ 70 – 85%) and C16 (~ 15 - 30%) in length. The chlorination levels by weight are between 35-40%. The chlorination process is largely random, though chlorination will occur first by direct addition at unsaturated sites in the unsaturated methyl esters present in the starting material.
