Reference
Endpoint:
appearance / physical state / colour
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
test procedure in accordance with generally accepted scientific standards and described in sufficient detail
Justification for type of information:
Company report on attempts to remove water
Qualifier:
no guideline followed
Principles of method if other than guideline:
FT-IR performed on a sample, before and after rotary evaporation of water, to investigate whether the identity of the MK310K remains unchanged on drying
GLP compliance:
no
Specific details on test material used for the study:
Sample Ref 91602-001; starting at ca 40% in water
Physical state at 20°C and 1013 hPa:
liquid
Form:
liquid: viscous
Colour:
Amber
Odour:
ammonia-like
Substance type:
organic

The water-free material produced was a gel-like consistency, but in the form manufactured and supplied, it is a mobile liquid in water.

Conclusions:
Not possible to remove water without decomposition. Report attached (using IR to demonstrate chemical changes on drying)
Supplied as a mobile solution in water.

Description of key information

Key value for chemical safety assessment

Physical state at 20°C and 1013 hPa:
liquid

Additional information

Considered likely to be solid if possible to isolate from water.

Liquid form is used for CSR
