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.
