|---|---|---|---|
| ASF | 101.4 * | 300.6/460.7 | 1.5 ± 0.2 |
| PHBH | 286.8 | 308.9 | 2.4 ± 0.3 |
| PHBH-10ASF | 253.2 | 288.1 | 2.3 ± 0.2 |
| PHBH-20ASF | 250.5 | 284.3 | 2.1 ± 0.1 |
| PHBH-30ASF | 223.6 | 279.1 | 2.0 ± 0.3 |
| PHBH-30ASF/10OLA | 258.4 | 292.0 | 2.0 ± 0.2 |
| PHBH-30ASF/20OLA | 226.3 | 283.5 | 2.0 ± 0.2 |
* Initial weight loss in ASF due to residual water evaporation.
