Glycol chitosan is a kind of chitosan derivative with hydrophilic glycol-branched. Glycol-chitosan enhances membrane permeability and lead in glycine Max Harosoy 63W cells. Glycol-chitosan has water solubility, biocompatibility and biodegradability. The inhibitory MIC values of ethylene glycol chitosan against Escherichia coli, Staphylococcus aureus and Salmonella enteritidis were 4 μg/mL, 32 μg/mL and <0.5 μg/mL, respectively.

| Molecular Weight | 633.64 |
| Formula | C24H47N3O16 |
| CAS Number | 123938-86-3 |
| Solubility (25°C) | DMSO ≥ 40 mg/mL Water 7.5 mg/mL |
| Storage |
Powder -20°C 3 years ; 4°C 2 years In solvent -80°C 6 months ; -20°C 1 month |
| Species | Mouse | Rat | Rabbit | Guinea pig | Hamster | Dog |
| Weight (kg) | 0.02 | 0.15 | 1.8 | 0.4 | 0.08 | 10 |
| Body Surface Area (m2) | 0.007 | 0.025 | 0.15 | 0.05 | 0.02 | 0.5 |
| Km factor | 3 | 6 | 12 | 8 | 5 | 20 |
| Animal A (mg/kg) = Animal B (mg/kg) multiplied by | Animal B Km |
| Animal A Km |
For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.
