- Irritant / corrosive response data:
- One drop of the undiluted test substance applied to the conjunctival sac of the eye produced very strong reddening within 10 min combined with enhanced secretion, corneal opacity, and slight chemical burning of the mucosa. The signs of mucosal irritation/corrosion were visible for at least 3 days. On day 3 ciliar injections and mucosal bleedings were observed combined with smeary secretion, slight chemosis and diffuse corneal opacity. After 6 days clear signs of irreversible corneal damage and iritis were observable including scar formation and cloudy corneal opacity. At day 8 slight reddening, slight mucosal bleedings, smeary secretion and cloudy corneal opacity were still visible.
At the end of the study period (day 24) irreversible signs of corneal damage were observed as well as ciliar injections in the lower half of the eyeball in two animals. Two animals were euthanized on day 6 of the study due to massive chemical burnings of the eye including black-brown necroses, strong bleedings/bloody secretions and foggy corneal opacity. - Interpretation of results:
- Category 1 (irreversible effects on the eye) based on GHS criteria
- Conclusions:
- 3-Aminopropan-1-ol causes severe eye damage.

Additional information
There are valid in vivo data available for the assessment of the skin and eye irritation potential of 3-aminopropan-1-ol.
Skin
A Draize test was performed with two White Vienna rabbits (BASF AG, 1979). A 1-hour exposure to 0.5 g of the unchanged test substance produced non-reversible severe erythema and edema (overall erythema score of 4 and edema score of 2.25 for the readings 24 and 48 h) and full thickness necrosis in both animals persisting at the final reading on day 8. A 3 min exposure led to strong erythema persisting till the end of the study period in 1/2 animals.
In a second report, two rabbits were exposed to the unchanged test substance for 1, 5 and 15 min under occlusive conditions (BASF AG, 1958). Slight erythema were reversible at least within 11 days, edema were not observed, while scaling was reported in one animal from day 4 on.
In a third report, 2 animals were exposed to the unchanged test substance for 1, 5, 15 min and for 20 hours under occlusive conditions (BASF AG, 1967). The test substance produced moderate to severe erythema but no edema after an exposure for 1 min under occlusive conditions. When the rabbits were exposed to 5 or 15 min under occlusive conditions also strong irritation was visible with strong erythema and no (5 min) to slight edema (15 min) in one animal. Overall erythema score was 2.0 and 2.5 respectively. After 5 min exposure soft necrosis occurred in 1/2 animals while the other animal showed desquamation from day 7 on. After 15 min of exposure necrosis were observed in both animals, one of them showing full thickness necrosis. Application of the test substance for one min under occlusive conditions resulted in moderate to strong erythema visible for at least 72 hours. In one animal strong desquamation was visible on day 7 after application.
Two other publications by Smith et al. (1962) and the American Cyanamide Co. (1954) judge 3-aminopropan-1-ol as corrosive to the skin of rabbits without showing details on the tests performed.
Eye
An in vivo test comparable to the Draize test was performed with four rabbits (BASF AG 1958). Eyes were left unwashed after application of ca. 0.1 mL 3-aminopropan-1-ol and were observed for 24 days. The test substance caused very strong reddening within 10 min combined with enhanced secretion, corneal opacity, and slight chemical burning of the mucosa. At the end of the study period (day 24) irreversible signs of corneal damage were observed as well as ciliar injections in the lower half of the eyeball in all animals. Two animals were euthanized on day 6 of the study due to massive chemical burnings of the eye including black-brown necroses, strong bleedings/bloody secretions and foggy corneal opacity.
The results of another Draize test (BASF AG, 1967) also induced severe chemical burns in rabbits within 10 min after substance application. After 8 days, at the end of the observation period, a severe ulceration and scar formation at the side of the eye lid was observed in one animal, as well as strong pus formation. In the second animal adhesions of the eye lids could be observed.
Two other publications by Smith et al. (1962) and the American Cyanamide Co. (1954) judged 3-aminopropan-1-ol as corrosive to the eyes of rabbits when applied undiluted, a 10 % dilution caused strong but reversible irritation and a 1% dilution caused only mild to moderate transient irritation. Details on the tests performed by the American Cynamide Corp. are not available.
Justification for classification or non-classification
Classification, Labeling, and Packaging Regulation (EC) No. 1272/2008
The available experimental test data are reliable and suitable for classification purposes under Regulation 1272/2008. The substance is considered to be classified as skin corrosive Category 1B (H314: “Cause severe skin burns and eye damage”) and has to be classified for serious eye damage Cat.1 (H318: “ Causes serious eye damage”) according to Regulation (EC) No 1272/2008 (CLP), as amended for the tenth time in Regulation (EU) No 2017/776.
