Induction
Concentration / amount:
Concentration of test material and vehicle used at induction:
a) Intradermale Induktion: Testsubstanz in 2 %-iger

Konzentration

b) Epidermale Induktion: Testsubstanz in 50 %-iger

Konzentration (0,5 ml)

Da im Vorversuch keine Anzeichen einer Hautreizung
beobachtet wurden, wurde die Haut vor der epidermalen
Induktion mit einer 10 %igen Zubereitung aus Na-Laurylsulfat
(SDS) in Vaseline vorgereizt.


Vehikel: corn oil

"ENGLISH"

a) Intradermal induction: Test substance in 2%

concentration

b) Epidermal induction: Test substance in 50%

concentration (0.5 ml).

Since no signs of skin irritation were observed in the
pretest, the skin was pretreated with a 10% preparation of
sodium lauryl sulphate (SDS) in vaseline prior to the
epidermal induction.

Concentration of test material and vehicle used for each challenge:
a) Auslösephase: Testsubstanz in 50 %-iger Konzentration

Any other information on results incl. tables

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

Signs of irritation during induction:
Sowohl bei der intradermalen als auch bei der epidermalen
Applikation wurden bei einigen Tieren der Prüf- und
Kontrollgruppe schwache Erytheme beobachtet, die auf die
Behandlung mit SDS zurückgeführt werden.

"ENGLISH"

Weakly developed erythemas, which were attributed to
treatment with SDS, were observed among some animals

from the test and the control groups in the case of both
intradermal and epidermal application.

Evidence of sensitisation of each challenge concentration:
Keine




"ENGLISH"

None

Other observations:
Es wurden keine Todesfälle und keine Anzeichen von
systemischer Toxizität beobachtet.


Im Verlauf der Studie war die Körpergewichtszunahme in der
Kontroll- und in der Prüfgruppe im selben Bereich.








"ENGLISH"

No mortalities and no signs of systemic toxicity were
observed.


In the course of the study, the body-weight gain in the
control and in the test groups was located within the same
range.
