Guidelines (Following is our recommended protocol. This protocol only provides a guideline, and should be modified according to your specific needs).
The final concentration of PEG300 can go up to 50% in the formulations for intravenous and intramuscular injection without any toxic effects. In PEG400 based solubility-enabling formulations in oral delivery of lipophilic drugs, both the 60% and the 100% PEG-400 formulations allowed full solubilization of the dose throughout the entire gastrointestinal tract-like journey[2][3].

DMSO : 100 mg/mL (250.00 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
H2O : 100 mg/mL (250.00 mM; Need ultrasonic)
* Note: If you choose water as the stock solution, please dilute it to the working solution, then filter and sterilize it with a 0.22 μm filter before use.

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (6.25 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (6.25 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

Protocolo
Rats[1]
Fischer-344 rats (10/group/sex) are administered polyethylene glycol 400 (PEG400) by gavage at 1.0, 2.5 or 5.0 mL/kg (1. l, 2.8 and 5.6 g/kg, respectively) body weight/day 5 days/wk for 13 wk. Animals in the control group receive water by gavage (5.0 mL/kg body weight/treatment day). An additional 10 rats/sex/group are assigned to the control and high-dose groups for a 6-wk recovery period. Evaluation of potential renal toxicity is identified as a primary objective[1].
