Description of key information
Key information is based on weight of evidence data from acute toxicity studies performed with the two main components aminopropanol and gluconate and dated before 2009.
Key value for chemical safety assessment
Acute toxicity: via oral route
Link to relevant study records
- Endpoint:
- acute toxicity: oral
- Type of information:
- experimental study

- weight of evidence
- Reliability:

- Justification for type of information:
- 3-aminopropan-1-ol is one of the constituents of Reaction mass of 3-hydroxypropan-1-aminium D-gluconate and N-(3-hydroxypropyl)-D-gluconamide.at a molar ratio of 1:1. The process used is a pseudo acid – base reaction in water that leads always to a mixture of the “amide” and the “salt” part. Both entities are required for the applications performances. With the manufacturing process used here it is not possible to separate the amide and salt part from the water phase. The 3-aminopropan-1-ol is the kation of the salt part.

- Executive summary:
Rats were fed by gavage 3000, 3600, 4320, 5190, 6210 mg/kg bw (30% (w/v) aqueous solution) potassium gluconate and were observed for signs of toxicity during a 14-day period. One animal
died in the 5190 mg/kg bw group and four animals in the 6210 mg/kg bw group. Deaths occurred between 5 and 21 hours after treatment. Survivors recovered gradually. The LD50 was calculated
(according to the method of Weil) to be 6060 mg/kg bw. However, the effects that were observed occurred at doses that exceed the accepted limit dose of 5000 mg/kg bw and the LD50 may be
related to high dosing.

Endpoint conclusion
- Endpoint conclusion:
- no adverse effect observed
- Quality of whole database:
- No study is provided with the test article. Instead, evidence of low toxicity is based on a separate study with one of the constituents, Aminopropanol.
Acute toxicity: via dermal route
Endpoint conclusion
- Endpoint conclusion:
- no adverse effect observed
- Quality of whole database:
- No study is provided with the test article. Instead, evidence of low toxicity is based on two separate studies with one of the constituents, Aminopropanol. An SIDS report on gluconates concludes that no hazard is to be expected from dermal exposure to this substance.
Additional information
Oral exposure of rats to 3-aminopropan-1-ol showed that not more than 10% mortality was recorded at doses up to and including 1000 mg/kg, five out of 10 animals died at 1470 mg/kg and all animals died at 2150 mg/kg.
Data on acute oral toxicity for sodium gluconate in rat fed by gavage at dosages of 3000, 3600, 4320, 5190, 6210 mg/kg bw (30% (w/v) aqueous solution)potassium gluconate and observed for signs of toxicity during a 14 -day period resulted in one animal dead in the 5190 mg/kg bw group and four animals dead in the 6210 mg/kg bw group. Deaths occurred between 5 and 21 hours after treatment. Survivors recovered gradually. The LD50 was calculated (according to the method of Weil) to be 6060 mg/kg bw. However, the effects that were observed occurred at doses that exceed the accepted limit dose of 5000 mg/kg bw and thus, the LD50 may be related to high dosing. No relevant oral toxicity data were found in the literature for the other substances of the category.
Justification for classification or non-classification
As studies in rat showed a relatively low toxicity of aminopropanol with an LD50 > 1000 mg/kg and of gluconate with an LD50 value > 2000 mg/kg bw, Reaction mass of 3-hydroxypropan-1-aminium D-gluconate and N-(3-hydroxypropyl)-D-gluconamide is non-toxic with a predicted LC50 > 2000 mg/kg.
