Description of key information

waxy solid

Key value for chemical safety assessment

Physical state at 20°C and 1013 hPa:
liquid

Additional information

C16 Alkylamidopropyltrimethylammonium Chloride is a white waxy solid at 20°C and 1013 hPa (visual assessment).

However, due to the substance being a waxy solid paste, the physical state "liquid" was chosen as key value for chemical safety assessment to generate more realistic exposure levels within the exposure and risk assessment.
