The original internal reported values for lot 6B308 and 16715 are 51.86
mN/m and 64.6 mN/m. The low value for lot 6B308 is most likely
influenced by contamination or run incorrectly and can be excluded
statistically. The other lots of JEFFAMINE® D-230 amine all measure
around 63 mN/M, ranging from approximately 61 to 65 mN/m. The newly
collected data, with statistical exclusion of the lot in question,
resets the reported 1 g/L surface tension average to 62.95 mN/m (see
table below). Since the average result using reliable data is above the
regulatory limit of 60 mN/m, the material is not a surfactant according
to that regulation and guidance.
the average surface tensions for each lot number results are deliberately displayed in order from lowest to highest.
The surface tension of the test item is 62.95 mN/m and therefore
considered to be not surface active (O'Connell, 2018).
