Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Any other information on results incl. tables

Maximum concentration not causing irritating effects in preliminary test: 50 %

Signs of irritation during induction:
Deutlich erkennbare Hautreizungen an den Injektionsstellen
nach intradermaler Induktion.

"ENGLISH"

Clearly identifiable skin irritation at the injection sites
after intradermal induction.

Evidence of sensitisation of each challenge concentration:
In der Testgruppe traten Hauteffekte bei 4/10 Tieren nach

48 h und bei 5/10 Tieren nach 72 h auf. Insgesamt reagierten
6/10 Tiere (60 %) in der Behandlungsgruppe. 3/10 Tiere in
der Testgruppe wiesen an beiden Beobachtungszeitpunkten
Hauteffekte auf.

"ENGLISH"

Skin effects occured in the test group at 4/10 animals 48 h
and at 5/10 animals after 72 h. 6/10 animals (60 %) of the
treatment group reacted all over. 3/10 animals of the
treatment group showed skin effects at both observation
times.

Other observations:
Aussehen und Verhalten der Tiere in der Testgruppe
unterschieden sich nicht von den Beobachtungen in der
Kontrollgruppe. Die Körpergewichtsentwicklung entsprach
derjenigen der Kontrollgruppe.

"ENGLISH"

Appearance and behaviour of the animals in the test group
did not differ from the animals in the control group.

The body weight development was the same as in the control
group.
