Referenceopen allclose all
Potassium sodium tartrate tetrahydrate (0.1 g) applied into the conjuntival sac of the right eye of two White New Zealand rabbits for 1 h according to EU test guideline B.5. revealed that the substance produced a mild conjuntival irritation in 1 of the two animals, which was fully reversible after 48h. Corneal, iris and conjunctival reddening scores were all zero at all observation periods and the substance is not classified as irritating although it may cause fully reversible slight edema of the conjunctiva and will cause discomfort of exposed individuals. Workplace experience supports this conclusion.
Endpoint conclusion
- Endpoint conclusion:
- no adverse effect observed (not irritating)
Respiratory irritation

Additional information
Irritation/Corrosion
Justification for read-across
There are no data on Irritation/Corrosion available for diammonium tartrate (CAS 3164 -29-2). To fulfil the standard data requirements defined in Regulation (EC) No. 1907/2006, Annex VII, 8.1 and 8.2., read-across from an appropriate substance is conducted in accordance with Regulation (EC) No. 1907/2006, Annex XI.
According to Article 13 (1) of Regulation (EC) No 1907/2006, "information on intrinsic properties of substances may be generated by means other than tests, provided that the conditions set out in Annex XI are met”. In particular for human toxicity, information shall be generated whenever possible by means other than vertebrate animal tests, which includes the use of information from structurally related substances (grouping or read-across) “to avoid the need to test every substance for every endpoint”.
For each specific endpoint the source substance(s) structurally closest to the target substance is/are chosen for read across, with regard to the requirements of adequacy and reliability of the available data. Structural similarities and similarities in properties and/or activities of the source and target substances are the basis of read-across. A detailed justification for the analogue read- across approach is provided in the technical dossier (see IUCLID Section 13).
As no experimental/measured data are available on Skin and Eye Irritation/Corrosion of diammonium tartrate (CAS 3164-29-2), read-across to reliable data on the analogue substance potassium sodium tartrate tetrahydrate (CAS 6381-59-5) was conducted.
Skin Irritation
The skin irritation properties of the test substance were tested in a study in rabbits according to EU Method B.4 (reference 7.3.1-1). They were exposed to 0.5 g of the unchanged test substance for 4 hours leading to an erythema and edema score of 0. Therefore, potassium sodium tartrate is not regarded as skin irritant.
Eye irritation
The eye irritation properties of the test substance were tested in a study in rabbits according to EU Method B.5 (reference 7.3.2-1). They were exposed to 0.1 g of the unchanged test substance for 1 h resulting in a cornea opacity/ iris/ conjunctivae score of 0 and an chemosis score of 0 in one animal and in the other a score of 1, which was fully reversible within 48 h. Based on the obtained results, potassium sodium tartrate is not eye irritating.
Justification for classification or non-classification
Based on the analogue read-across approach, the available data on irritation do not meet the classification criteria according to Regulation (EC) 1272/2008, and are therefore conclusive but not sufficient for classification.
