2.1. Materials.
The vegetable oil (VO) used was a refined, bleached, and deodorized high oleic safflower oil obtained from a local distributor (Coral Internacional, San Luis Potosi, Mexico). Previous characterization indicated that the major triacylglycerides (TAGS) in the VO used were OOO (65.65% ± 0.15%), LOO (16.26% ± 0.04), and POO (8.58% ± 0.04), and as minor TAGS components: StOO (2.64% ± 0.01%), LLO (2.25% ± 0.02%), POL (1.70% ± 0.11), StLL (0.87% ± 0.05%), and LLL (0.46% ± 0.01%) (O = oleic acid; L = linoleic acid; St = stearic acid; P = palmitic acid) (Alvarez-Mitre et al., 2012). The micronized refined candelilla wax (CW), supplied by Multiceras (Monterrey, Mexico) was previously characterized by gas chromatography coupled with mass spectrophotometry after derivatization of the CW with N,O-Bis(trimethylsilyl)trifluoroacetamide following the procedure described by Ortega-Salazar (2012). The results indicated that the main component of the CW were n -alkanes (45.75% ± 1.01),n -aliphatic alcohols (5.27 ± 1.40),n -fatty acids (15.17% ± 2.03), long chain esters (7.45% ± 0.61), triterpenic alcohols (23.41% ± 1.55), and esters of triterpenic alcohols (7.45% ± 0.17).
