Applicant's summary and conclusion
- Interpretation of results:
- Category 2 (irritant) based on GHS criteria
- Conclusions:
- Acute dermal irritation study was carried out to assess the irritation potential of Diethylene Glycol Bis(3-aminopropyl) Ether. Primary Irritation score after 24 hours for Diethylene Glycol Bis(3-aminopropyl) Ether was Grade 6.
Based on this grade, Diethylene Glycol Bis(3-aminopropyl) Ether can be considered moderately irritating to rabbit skin. - Executive summary:
Acute dermal irritation study was carried out to assess the irritation potential of Diethylene Glycol Bis(3-aminopropyl) Ether. Primary skin irritation on rabbits was recorded in a 10-grade ordinal series and was based upon the severest reaction that develops on the clipped abdominal skin of each of five albino rabbits within 24 hours of the uncovered application of 0.01 ml of undiluted sample or of solutions in water, propylene glycol, or acetone.
Grade 1 indicates no irritation and Grade 2 the least visible capillary injection from the undiluted chemical. Grade 6 indicates necrosis when undiluted and Grade 10 indicates necrosis from a 0.01% solution. Primary Irritation score after 24 hours for Diethylene Glycol Bis(3-aminopropyl) Ether was Grade 6.
Based on this grade,Diethylene Glycol Bis(3-aminopropyl) Ether can be considered moderately irritating to rabbit skin.
