- Interpretation of results:
- GHS criteria not met
- Conclusions:
- not sensitising
- Executive summary:
The skin sensitisation potential of the test item was investigated in the Guinea-Pig Maximisation Test with the Dunkin Hartley albino strain, whose sensitivity to Benzocaine had been demonstrated.
The choice of doses for the main experiment based on the results of the pilot study. The animals showed a very homogeneous reaction to the administration of the test item.
No clinical signs were observed in the course of testing. The body weights and the body weight gain were not affected by the treatment.
The intracutaneous injection of the 5 % (w/v) suspension of the test item in arachis oil induced slight oedema and slight erythema (grade 1). In combination with sensitisation potentiating FCA slight to moderate erythema and oedema were observed.
The pretreatment with 10 % sodium lauryl sulphate in vaseline caused the intended slight to moderate erythema in all animals on day 7.
The epicutaneous administration of the 25 % (w/w) mixture of the test item with vaseline did not cause any irritation.
The challenge with the 25 % (w/v) mixture of the test item with vaseline did not cause any irritation signs in all animals. The skin fold thickness was not affected by the treatment.

Endpoint conclusion
- Endpoint conclusion:
- no adverse effect observed (not sensitising)
Respiratory sensitisation
Endpoint conclusion
- Endpoint conclusion:
- no study available
Justification for classification or non-classification
Considering results of the structural similar compound Iodotris(triphenylphosphino)copper,
Iodo(triphenylphosphino)copper has not to be classified as "sensitising to skin", since the classification criteria according to (EU) No. 1272/2008 are not fulfilled.
