Producer: 
Eastman
Eastman Cellulose Acetate Butyrate (CAB-381-2BP) grade ester is a slight modification of the standard CAB-381-2 cellulose acetate butyrate and has a higher hydroxyl and acetyl content and lower butyryl content. The BP grade was designed primarily to meet the needs of European formulators. When CAB-381-2BP is dissolved in appropriate solvents, a clear, colorless solution is produced.Eastman CAB-381-2BP is based on cellulose, one of the most abundant natural renewable resources. The calculated approximate bio-content value of 41% for Eastman CAB-381-2BP was determined by using six bio-based carbon atoms per anhyroglucose unit divided by the total number of carbons per anhyroglucose unit. Although the value reported is not specifically measured for bio-carbon, it can be estimated based on typical partition data.
