The water phase of the W/O emulsions that were investigated
by both high and low resolution NMR contained 800 mM TMACl
in a mixture of D2O/H2O (50:50, wt%) and the oil phase consisted
of 2.5 wt% PGPR in Hoso. Both phases were heated to 60 C and
the W/O emulsions (40 g of 50:50, w/w) were mixed at 60 C with
an Ultra-Turrax (type S25KV – 25G, IKA-Werke, Germany) at
6500 rpm for 4 min.
