Characterization and evaluation of novel sustainable polymers derived from renewable rosin

This study aims to prepare low-cost biomaterials from renewable natural resources (rosin).

Preparation of different biomaterials, ethylene glycol maleic rosin (EGMR), glycerol maleic rosin, pentaerythritol maleic rosin and sorbitol maleic rosin (SMR) esters, then evaluated by stability studies, moisture absorption, swelling index parameters, thermogravimetric analysis and skin irritation studies.

The prepared rosin derivatives had excellent moisture safety, according to the results. From EGMR to SMR, the swelling indices increase.

These rosin biomaterials were used in coating, especially in the field of pharmaceutical coating, and good results were obtained in this study.

As these biomaterials rosin derivatives have excellent moisture resistance, they are recommended for use as coating materials for moisture-sensitive drugs.

There has recently been a lot of interest in researching the effects of rosin derivatives in various drug delivery systems.
