* Formulations: F1 (CS: PVA:ox-CNO 30.00:70.00:0); F2 (CS:PVA:ox-CNO 29.50:70.00:0.50); F3 (CS:PVA:ox-CNO 29.00:70.00:1.00); F4 (CS:PVA:CS-g-CNO 29.50:70.00:0.50); F5 (CS:PVA:CS-g-CNO 29.00:70.00:1.00). ** Values correspond to means ± standard deviation. Different superscript letters in the same column indicate significant differences (p < 0.05).
