Properties of the three materials tested in this study. The concentration of CMHA-S or HA was determined usin a carbazole assay (n = 6). Viscosity and shear moduli are averages of 8 samples.

| Viscosity at 0.25 s−1 (Pa·s) | 2.82 ± 0.50 | 0.09 ± 0.03 | 0.14 ± 0.03 |
| Viscosity at 2.5 s−1 (Pa·s) | 0.66 ± 0.06 | 0.17 ± 0.01 | 0.21 ± 0.01 |
| G′ at 2.5 Hz (Pa) | 4.14 ± 1.23 | 4.46 ± 1.47 | 3.25 ± 1.19 |
| G′′ at 2.5 Hz (Pa) | 8.75 ± 1.21 | 4.37 ± 0.70 | 6.39 ± 1.80 |
| tan δ at 0.25 Hz | 0.7 | 2.4 | 1.6 |
