Two animals were treated for 1, 5, 15 min using occlusive conditions with 3-aminopropyldiethylamine. An application site of 2.5x2.5 cm was covered with the liquid test substance. After the application time (1, 5, 15 min) the skin was washed with Lutrol (conc.) and Lutrol/water (1:1). The animals were observed for 8 days and skin changes were recorded daily. The report describes findings after 24 hours and at the end of the observation period (8 days). For a final evaluation, the findings after 48 and 72 hours from the raw data were taken into account. Twenty-four hours after the 1, 5 or 15-min exposure, leather-like brown-reddish necrosis with partly reddish partly anaemic surroundings was observed. Eight days post application hard, almost black necrosis was observed.
Reference
The application of the test substance caused necrosis to the exposes tissues and therefore a precise evaluation of erythema and edema scores was not possible.
Major findings after 1, 5 or 15 min exposure: After 24 h leather-like brown-reddish necrosis with partly reddish partly anaemic surroundings was observed. 8 days post application hard, almost black necrosis was observed.

- Executive summary:
Fifty µL of 3-aminopropyldiethylamine were applied to the conjunctival sac of one eye in 2 animals. The animals were observed after 10 min, 1 and 3h on the day of treatment and up to 8 days afterwards. Findings were recorded daily. The eyes were not washed out after 24 hours.The application of the test substance caused necrosis and suppuration to the eyes and therefore a precise evaluation of edema and iritis scores was not possible. Shortly after exposure (10 min) animals showed bloody eye discharge and corrosion was noted. After 2 days, swelling of the eyelids was observed. Five days post application vessel ingrow (animal 1) and suppuration (animal 2) was noted. Animal 1 was sacrificed ahead of schedule on day 5 (complete leakage of eye).

Additional information
Skin Irritation-Corrosion
In vitro studies
To evaluate the potential skin corrosivity of 3-aminopropyldiethylamine, the pH and acidic/alkaline reserve was measured according to the method described by Regnier and Imbert (ATLA, 1992, 20, 457-465) and Froment (Arkema unpublished data, 1993). Under the test conditions, the results are as follow:
Test item |
pH |
log R (acidic/alkaline reserve |
Physical-chemical index (I) I = pH + log R, for pH =7 I = (14 -pH) + log R, for pH < 7 |
3-aminopropyldiethylamine |
11.9 |
1.6 |
13.5 |
According to the method, a substance is considered as potentially corrosive to the skin if at least 2 of the 3 following criteria are fulfilled:
pH= 2.5 or pH =9.5; log R = 0 and/ot I= 10.
3-aminopropyldiethylamine is considered as potentially corrosive to the skin.
In vivo studies
In a key study (BASF, 1961), two animals were treated for 1, 5, 15 min using occlusive conditions with 3-aminopropyldiethylamine. An application site of 2.5x2.5 cm was covered with the liquid test substance. After the application time (1, 5, 15 min) the skin was washed with Lutrol (conc.) and Lutrol/water (1:1). The animals were observed for 8 days and skin changes were recorded daily. The report describes findings after 24 hours and at the end of the observation period (8 days). For a final evaluation, the findings after 48 and 72 hours from the raw data were taken into account. Twenty-four hours after the 1, 5 or 15-min exposure, leather-like brown-reddish necrosis with partly reddish partly anaemic surroundings was observed. Eight days post application hard, almost black necrosis was observed.
In a suporting study (Clouzeau, 1988), the acute dermal irritation of 3-aminopropyldiethylamine was evaluated inalbino rabbits. 0.5 mL of the test substance was applied during 4 hours in 1 rabbit on the right clipped flank. The left untreated flank was used as negative control. The cutaneous reaction was observed one hour, 24, 48, 72 hours after removal of the dressing. After 1 hour, 24, 48 and 72 hours, a tissular necrosis was noted on the site of the cutaneous application. The rabbit has been sacrificed for ethical reasons 72 hours after the end of exposition.

3-aminopropyldiethylamine is considered as potentially severely irritating to the eye.
