Characteristic of bioadhesive polymer

Bioadhesive polymers have their unique characteristic.

Following is the Characteristic of bioadhesive polymer

-bioadhesive polymer and degradation products should be non-toxic, non-irritant and free from leachable impurities.

- Bioadhesive polymer should have good spreadability, wetting, swelling and solubility, and biodegradability properties.

- Bioadhesive polymer shall adhere quickly to the mucosa and should process sufficient mechanical strength.

- Bioadhesive polymer possesses peel, tensile and shear strength at the bioadhesive range.

- Bioadhesive must be easily available and its cost should not be high.

- Bioadhesive polymer should show bioadhesive properties in both dry and liquid state.

- Bioadhesive polymer should have an acceptable shelf life.

- Bioadhesive should have optimum molecular weight.

- Bioadhesive polymer should have spatial confirmation.

- Bioadhesive should have sufficiently cross-linked but not to the degree of suppression of bond forming groups.
