In this skin irritation study New Zealand White rabbits were treated with the test item 1,3,5 Triisopropylbenzene. The test item was applied to the intact skin of rabbits in a single dose of 0.5 ml. The irritation symptoms were examined at 1, 24, 48 and 72 hours after patch removal.
The animals’ individual mean scores (considering readings at 24, 48 and 72 hours after patch removal) for erythema and oedema were 0.00 and 0.00 respectively. During the study the general state and behaviour of animals were normal. There were no notable body weight changes during the contact and observation period.
No primary irritation symptoms, such as erythema and oedema, or other signs occurred during the observation period.

- Executive summary:
The acute eye irritation study with test item 1,3,5-Triisopropylbenzene was performed in New Zealand White rabbits. The irritation effect of the test item was scoring according to the Draize method (Draize, 1959; OECD Guideline 405, 2012).
The test item was placed into the conjunctival sac of left eye of each animal. The untreated right eye served as control. 0.1 ml of the test item was used for the study, in a single dose. The eyes of the test animals were not washed out.
1 hour after the single application of test item into the eye of the rabbits, slight redness and chemosis occurred. 24 hours after treatment all animals was free of symptoms. The 24/48/72 hour mean cornea opacity score, iris score, and chemosis score was 0.00, 0.00, and 0.00, respectively.
During the study the control eyes of animals were symptom-free. No systemic toxicity was observed. The body weight of animals corresponded to their species and age. Sign of pain and distress as discharge was not observed in animals during the study.
The test item 1,3,5-Triisopropylbenzene applied to the rabbits' eye mucosa caused slight conjunctival irritant effects which were fully reversible within 24 hours.

Additional information
Justification for classification or non-classification
Skin corrosion/irritation:
No primary irritation symptoms, such as erythema and oedema, or other signs occurred during the observation period following exposure to 100% test item. Therefore, according to EC 1272/2008 as amended, the test substance does not meet the criteria for skin corrosion/irritation classification.
Serious eye damage/eye irritation
The 24/48/72 hour mean cornea opacity score, iris score, and chemosis score was 0.00, 0.00, and 0.00, respectively following exposure to 100% test item. Therefore, according to EC 1272/2008 as amended, the test substance does not meet the criteria for serious eye damage/eye irritation classification.
