【BETA-CYCLODEXTRIN】Product performance:
1. Solubilization:
Neutral, vague and pasty APIs can be effectively combined with butyl betacycline, so that compounds with different solubility in the API can be increased by 10 to 25,000 times.
2. Convenience:
Sodium butyl beta cyclodextrin has a good biological seam, which can be injected, exposed, externally used and throat, throat and so on.
3. Good safety:
Normally, after an emergency occurs, it can be quickly and completely removed from the accident. In experiments and automobiles, subacute use and toxicity studies provide safe data and are used for drug therapy.
4. Good stability:
The absorption of cyclodextrin sodium bromide and beta-cyclodextrin can provide a more beneficial protective environment for the crude drug in its lipophilic cavity, while the hydrophilic surface provides good solubility and solubility.
