Applicant's summary and conclusion
- Interpretation of results:
- not irritating
- Remarks:
- Migrated information Criteria used for interpretation of results: OECD GHS
- Conclusions:
- The results of this study indicate that the test material may have little irritant effect in the eye. The composition of the test material is estimated to be 40% active ingredient (incl NaCl) and 60 % water. The active ingredient is Amines, N-[3-[(3-aminopropyl)amino]propyl]-N’-(C16-18 and C18-unsatd. alkyl)trimethylenedi-, N-(carboxymethyl) derivs., sodium salts (CAS no 2060541-47-9). The response observed appears to have been in an unusually sensitive animal. The animals were only observed for 72 hours and therefore it can not be judges if the effects are reversible within 21 days. However after 72 hours compared with the 24 reading the severity of the effects had decreased some in the affected animal. The active ingredient Amines, N-[3-[(3-aminopropyl)amino]propyl]-N’-(C16-18 and C18-unsatd. alkyl)trimethylenedi-, N-(carboxymethyl) derivs., sodium salts (CAS no 2060541-47-9) may not be classified as an irritant to the eye according to GHS.
- Executive summary:
According to methods similar to OECD and under GLP 0.1 ml aliquots of the test material were instilled into the right eye of each of six rabbits, the other eye remaining untreated as a control. The irritation produced in the treated eye of all rabbits was assessed 24, 48 and 72 hours after dosing. 24 hours after dosing iris inflammation and severe conjunctival irritation were apparent in one rabbit of the group, no response to treatment being observed in other , animals o f the group. Moderate conjunctival irritation was maintained by the one rabbit throughout the study.
