Key value for chemical safety assessment

Boiling point at 101 325 Pa:
500 °C

Additional information

According to different model calculations, the boiling point of Chlorhexidine base is predicted to be >500°C. However, salts of Chlorhexidine decompose before boiling, Chlorhexidine digluconate starts to decompose at approximately 157°C and decomposition of the dihydrochloride is beginning at approx. 280°C. Therefore, it is expected that Chlorhexidine base will also decompose before boiling.
