Conclusions:

The registered substance is considered to be skin irritating.

Executive summary:

The skin irritating potential of tripropenyl succinic anhydride was investigated according to test guidline OECD 404. Very slight to well-defined erythema and very slightly to moderate edema were seen on during the observation period. All the effects were fully reversible. The average values of erythema and edema scores at time points of 12, 48 and 72 h after treatment are 1.6 and 1.1, respectively. In addition, Skin dry, brittle and scaly were observed after 14d. Based on these findings, the registered substance is considered to be skin irritating.

Remarks on result:

other: see Irritant/corrosive response data in the following

Irritant / corrosive response data:

100% group: Light corneal cloudiness was observed. The conjunctiva showed a diffuse carmine to fleshy redness and a marked swelling with partial retraction of eyelids. The treated eye had severe discharge.
10% group: Light corneal cloudiness was observed. The blood vessels of the conjunctiva were injected. Severe discharge was observed. All the effects were reversible exept for the light redness and swelling.
1% group: The treated animal showed significantly injected blood vessels and slight discharge. These findings were reversible in 48 hours.

Interpretation of results:

corrosive

Remarks:

Migrated information Criteria used for interpretation of results: EU

Conclusions:

It is concluded that the test substance may cause serious eye damage.

Executive summary:

The eye irritation/corrosion potential of the test item was investigated using Albino Himalaya rabbits. The test item of 1, 10 and 100% was applied by instillation of 0.1 ml into the left eyes of each 2 animals. The effects were observed after 1, 7, 24, 48 and 72 hours after application. After 24 hours, the treated eyes were washed with physiological saline solution. Light to severe effects were observed in all the treated groups. In the 100% group light corneal cloudiness was observed. The conjunctiva showed a diffuse carmine to fleshy redness and a marked swelling with partial retraction of eyelids. The treated eye had severe discharge. All the effects were irreversible during the observation period. In the 10% group, light corneal cloudiness was observed. The blood vessels of the conjunctiva were injected. Severe discharge was observed. All the effects were reversible exept for the light redness and swelling. In the 1% group, the treated animal showed significantly injected blood vessels and slight discharge. These findings were reversible in 48 hours. Based on the effects observed, it is concluded that the test substance may cause serious eye damage.

Justification for classification or non-classification

Based on the available data, it is concluded that tripropenyl succinic anhydride is subject to classification and labeling according to Directive 67/548/EECand Regulation 1272/2008/EC regarding skin/eye irritation/corrosion. The registered substance is classified as R38 and Cat. 2 (H315: cause skin irritation) for skin irritation, R41 and Cat. 1 (H318: causes serious eye damage) for eye irritation/corrosion.
