Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Viscosity
Administrative data
- Endpoint:
- viscosity
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 11.12.2003
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Justification for type of information:
- Purified K-HDO is a powder. Therefore no viscosity can be determined for the purified active substance. However because K-HDO is only manufactured as a 30 % aqueous formulation - Xyligen 30F - the viscosity has been determined for Xyligen 30F.
