Anion exchange was achieved by mixing 5 g of ZCA HDS with 500 mL of 0.1 M sodium stearate solution in chloroform for 24 h at room temperature with frequent shaking. The supernatant was decanted and replaced by a fresh solution for another 24 h with this process repeated for the third time. The exchanged HDS product, zinc copper hydroxy stearate (ZCHS) was recovered by filtration, washed with 500 mL of methanol, followed by 500 mL of acetone and plentiful amounts of water before drying at 100°C overnight to drive off residual solvents. 

An HDS additive, zinc/copper hydroxy stearate, was melt-blended with low density poly(ethylene). X-ray diffraction analysis of the composite materials was similar to that found with copper hydroxy dodecyl sulfate combined with poly(vinyl ester), where nanocomposite formation was observed, but additional work is necessary for full characterization of the dispersion. The (nano) composites were found to have better thermal stability via TGA and improvement in PHRR in cone calorimetry. However, smoke production was observed to increase. The 5% loading had better overall performance than 10% in terms of thermal stability and most fire properties.

Some of the more common calcium soaps are the stearate, sulfonate, phenate, myristate, arachidate, 12-hydroxy-stearate, laurate, oleate, 2-ethyl-hexanoate, ricinoleate and naphthenate. They are produced either by double decomposition or direct reaction with slaked lime or calcium chloride.

Column chromatography on silicic acid has also been used to isolate polar fatty acid esters, and as examples, methyl 9- and 13-hydroxy-stearate [224] and the acetate derivatives of methyl 9,10-dihydroxy-myristate and 9,10-dihydroxy-palmitate [178] have been resolved by this technique. A small-scale column procedure, with Florisil as adsorbent, has been described for separating normal from 2-hydroxy fatty acid esters, i.e. the component fatty acids of sphingoglycolipids [122].
