Endpoint:
appearance / physical state / colour
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: accepted laboratory method
Principles of method if other than guideline:
visual observation during a study on determination of melting and boiling point
GLP compliance:
no
Physical state at 20°C and 1013 hPa:
solid
Form:
other: paste
Colour:
white
Odour:
other: not reported
Substance type:
organic
Conclusions:
C12-18 alkyldimethyl ammonium chloride is described to be solid.
Executive summary:

For the determination of physico-chemical properties, the solvent was almost completely removed by lyophilisation. The dried test item Di-C12-18 alkyldimethyl ammonium chloride at 20 °C and 101.3 kPa is a white, a little pasty, solid.

Description of key information

solid

Key value for chemical safety assessment

Physical state at 20°C and 1013 hPa:
liquid

Additional information

For the determination of physico-chemical properties, the solvent was almost completely removed by lyophilisation. The physical state of the dried test item Di-C12-18 alkyldimethyl ammonium chloride at 20 °C and 101.3 kPa is white, a little pasty, solid. However, the substance is manufactured and marketed only in solution, thus, 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.
