About This Product
Soy methyl ester, also called soya methyl ester, is the fatty acid methyl ester of soybean oil (CAS 68919-53-9). The biodiesel grade is specified against IS 15607:2022, whose limits include an ester content of 97.0% by mass min, a PMCC flash point of 150 °C min, sulphur at 10.0 mg/kg max, water at 750 mg/kg max, and iodine value no higher than 120 g I₂/100 g. On a tested batch, kinematic viscosity at 40 °C measured 4.85–5.10 cSt and the cold filter plugging point was 2 °C. Its main outlet is as biodiesel, blended into mineral diesel or burned neat where engines and local rules permit. An acid value capped at 0.50 mg KOH/g and an oxidation stability at 110 °C of at least 8 h are the limits that matter most for storage and fuel-system care. The same ester can also act as a bio-based solvent or an oleochemical feedstock. Before ordering, agree which limits of the standard apply, the test methods, the cold-flow performance needed for the climate of use and the packaging. Ask for the up-to-date specification sheet, an SDS and a lot-specific analysis certificate, then check that the fuel satisfies the blending rules and engine requirements where it will be used.
