Mechanical properties (mean ± standard errors) of model waxes (18% pentacosane, 68% palmityl palmitate, 14% fatty acid) with varying fatty acid compositions. Four mechanical parameters were measured: compressive yield stress (A), stiffness (B), resilience (C) and compressive stress at proportional limit (D). N = 10 samples for each column. Matching letters above columns indicate no significant difference between the columns; differing letters indicate a significant difference.
