Calculation of the RHLB in oil phase We measured saponification and acid indexes and calcu- lated the HLB of each oil phase using equation 2. Table 6 shows results of saponification and acid indexes and bal- ance lipophilic-hydrophilic (HLB) for rapeseed oil, sal- mon oil and soya lecithin. The HLB of the Miglyol 812 is 15.36 according to Macedo et al. [22].
