Description of key information
A study performed according to OECD 423, tested Phosphorous acid, tri-C12-14-alkyl esters with 6 female SD albino rats. The test item was administered pure by gavage at 2000 mg/kg bw and no mortality was observed, no effects on behaviour and body weights and no effects was seen at macroscopically examinations of necropsy.
Phosphorous acid, tri-C12-14-alkyl esters oral LD50 cutt off was > 5000 mg/kg bw
This value was supported by the LD 50 determined > 5000 mg/kg bw in a 401 study with the triisodecyl phosphite used for read across.
Two other studies were performed with inhalation and dermal routes:
- on rats (nose only) with aerosol (mass median diameter calculated to be 0.48 µm) form during 1 hour, LC50 inhalation > 12600 mg/m3 (maximum dose tested)
- a test was performed with rabbits, without vehicle and during 1 hour application. LD50 dermal > 5000mg/kg bw

- Other findings:
- no other findings
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Under the conditions of the test, a oral LD50 cutt off > 5000 mg/kg bw was considered for Phosphorous acid, tri-C12-14-alkyl esters.
- Executive summary:
Phosphorous acid, tri-C12-14-alkyl esters was tested in a acute toxicity class method, according to OECD 423 test guideline and without any deviation. The study was considered as reliable but was not performed under GLP conditions and a reliability 2 was then associated.
Six female Sprague Dawley rats were given 2000 mg/kg bw test substance by gavage and no clinical sign nor behaviour comportment were found. No mortality occured even after 14 day observation period.
Phosphorous acid, tri-C12-14-alkyl esters was then considered as not harmful if swallowed and could be not classified for this endpoint, according to the GHS classification criteria.

Additional information
Justification for classification or non-classification
Using data on Phosphorous acid, tri-C12-14-alkyl esters or read across with the analogue triisodecyl phosphite, and because the tested aerosol diameter was < 1µm (then the worst case is consider), Phosphorous acid, tri-C12-14-alkyl esters is considered to be not harmful neither by oral, inhalation nor by dermal route.
