Description of key information
The substance did not lead to skin irritation during in-vitro testing
The severity of the results in the Eye Irritation (BCOP) study was sufficiently low to confirm that the substance was not Eye Dam 1
However, in view of signficant effects, and taking into account the potential irritancy of at least one of the main starting materials / dissociation products, a classification of Eye Irrit 2 is considered valid and no further testing has been performed.
Key value for chemical safety assessment
Skin irritation / corrosion
Link to relevant study records
- Endpoint:
- skin irritation: in vitro / ex vivo
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 15 minute exposure
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Justification for type of information:
- Guideline study 2018 to GLP.
All quality crieteria met - Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 439 (In Vitro Skin Irritation: Reconstructed Human Epidermis Test Method)
- GLP compliance:
- yes (incl. QA statement)
- Specific details on test material used for the study:
- PAH 330/132/1A
The sample had been partly concentrated up to ca 50% (repored 49.38) to prepare as concentrated form of the material as possible for testing.
Attempts to concentrate further appeared to impact on stability. - Test system:
- human skin model
- Source species:
- human
- Cell type:
- non-transformed keratinocytes
- Vehicle:
- unchanged (no vehicle)
- Control samples:
- yes, concurrent negative control
- yes, concurrent vehicle
- Amount/concentration applied:
- The test item was applied topically to the corresponding tissues ensuring uniform covering.
10 µL (26.3 µL/cm2) of the test item was applied to the epidermis surface - Duration of treatment / exposure:
- 15 minutes
- Duration of post-treatment incubation (if applicable):
- 42 hours
- Number of replicates:
- 3
- Irritation / corrosion parameter:
- % tissue viability
- Run / experiment:
- Average
- Value:
- ca. 66.6
- Vehicle controls validity:
- not applicable
- Negative controls validity:
- valid
- Positive controls validity:
- valid
- Other effects / acceptance of results:
- No other effects reported
The solution containing the test item was a yellow color. This color was attributed to the intrinsic color of the test item itself. It was therefore unnecessary to run color correction tissues - Interpretation of results:
- GHS criteria not met
- Conclusions:
- Considered non-classified
- Executive summary:
The relative mean viability of the test item treated tissues was66.6% after the 15‑Minute exposure period and 42‑Hours post‑exposure incubation period.

- Endpoint conclusion:
- no adverse effect observed (not irritating)
Eye irritation
Link to relevant study records
- Endpoint:
- eye irritation: in vitro / ex vivo
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Justification for type of information:
- Guideline study performed 2017 to GLP

- according to guideline
- Guideline:
- EU method B.47 (Bovine corneal opacity and permeability test method for identifying ocular corrosives and severe irritants)
- GLP compliance:
- yes (incl. QA statement)
- Specific details on test material used for the study:
- Identification: Dodecenyl succinic acid, compound with 2,2',2''-nitrilotriethanol (partially solvent extracted)
Batch: PAH 330/132/1A
CAS Number: 64396-12-9
Purity: ~49.38%
Physical state/Appearance: slightly opaque amber colored viscous liquid - Species:

- yes, concurrent positive control
- yes, concurrent negative control
- Amount / concentration applied:
- 0.75 mL of the test item or control items were applied to the appropriate corneas.
- Duration of treatment / exposure:
- The holders were gently tilted back and forth to ensure a uniform application of the item over the entire cornea.
Each holder was incubated, anterior chamber uppermost, at 32 ± 1 ºC for 10 minutes. - Duration of post- treatment incubation (in vitro):
- 2 hours
- Irritation parameter:
- cornea opacity score
- Run / experiment:
- 1
- Value:
- ca. 24.1
- Vehicle controls validity:
- not applicable
- Negative controls validity:
- valid
- Positive controls validity:
- valid
- Interpretation of results:
- Category 2 (irritating to eyes) based on GHS criteria
- Conclusions:
- The severity of the results was sufficiently low to confirm that the substance was not Eye Dam 1
However, in view of signficant effects, and taking into account the potential irritancy of at least one of the main starting materials / dissociation products, a classification of Eye Irrit 2 is considered valid and no further testing has been performed.
Reference
The positive control In Vitro Irritancy Score was within the range of 31.6 to 58.7.
The negative control gave opacity of ≤3.0 and permeability ≤0.077.
Endpoint conclusion
- Endpoint conclusion:
- adverse effect observed (irritating)
Respiratory irritation
Endpoint conclusion
- Endpoint conclusion:
- no study available
