EC number: 213-067-8 | CAS number: 921-53-9
Skin sensitisation
Administrative data
- Endpoint:
- skin sensitisation: in vivo (LLNA)
- Type of information:
- migrated information: read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- key study
- Reliability:

- Rationale for reliability incl. deficiencies:
- other: Although reported GLP the information originated from a detailed review study that refers to an unpublished study. Thereby full details are nonot available for examination.

Constituent 1
In vivo test system
Test animals
- Species:
- mouse
- Strain:
- CBA
- Sex:
- female
Study design: in vivo (LLNA)
- Vehicle:
- dimethylformamide
- Concentration:
- 25 microliters of test material. According to OECD Guideline.
Concentrations used: 5.0, 10.0 and 25% tartaric acid - No. of animals per dose:

Results and discussion
In vivo (LLNA)
Results
- Parameter:
- SI
- Remarks on result:
- other: At 5.0 %: 1.0 At 10.0%: 0.9 At 25.0%: 1.5 LLNA EC3% - Not calculated
Applicant's summary and conclusion
- Interpretation of results:
- not sensitising
- Remarks:
- Migrated information
- Conclusions:
- Tartaric acid can be considered as a non-sentitiser as determined by OECD test guideloin 429. This information is fully relevant towards read across to potassium sodium tartrate as the salt dissociates in solution into the tartrate group, yielding an identical active organic group in solution.
- Executive summary:
Tartaric acid can be considered as a non-sentitiser as determined by OECD test guideline 429. This information is fully relevant towards read across to potassium sodium tartrate as the salt dissociates in solution into the tartrate group, yielding an identical active organic group in solution.
