The recent reclassification of C12–C14 glycidyl ether as a Category 1B reproductive toxicant requires full CMR labeling at concentrations above 0.3%, prompting many formulators to seek alternatives. Our Mergisol range of epoxidized fatty acid esters offers a 95% bio‑based option without hazard labeling. In the March issue of the German journal Farbe und Lack, these esters were benchmarked against C12–C14 glycidyl ether. The article is available to subscribers here.

The results in short:
– You will need roughly 2% higher concentration to reach the same target viscosity.
– Final properties like Shore D hardness and chemical resistance are not affected.
– Pot life and initial curing are slightly extended.

The study evaluated viscosity reduction, reactivity, cure development, pot life, and chemical resistance. The findings confirm that Mergisol meets the functional requirements of reactive diluents in epoxy formulations while offering a non‑CMR alternative. An English version of the article will also appear in the European Coatings Journal (ECJ) in May.
