EC number: 271-807-5 | CAS number: 68608-88-8 This substance is identified by SDA Substance Name: C11-C13 branched alkyl benzene sulfonic acid and SDA Reporting Number: 25-096-00.
Endpoint summary
Administrative data
Description of key information
Studies were conducted to evaluate the skin and eye irriation potential of the source substance, Benzenesulfonic acid, 4-C10-13-sec-alkyl derivs EC 287-494-3, CAS 85536-14-7. Which is strucutrally similar to the target substance, with differences in the branching of the alkyl side chain.
Key value for chemical safety assessment
Skin irritation / corrosion
Endpoint conclusion
- Endpoint conclusion:
- adverse effect observed (irritating)
Eye irritation
Endpoint conclusion
- Endpoint conclusion:
- adverse effect observed (irritating)
Additional information
Studies were conducted to evaluate the skin and eye irriation potential of the analogue substance benzenesulfonic acid, 4 -C10 -13 -sec-alkyl derivs. For skin, the shaved backs of three male and three female rabbits were exposed for 4 hours to 0.5 ml of the test substance and observed for up to 14 days. Significant reddening was observed throughout at least day 9. Swelling was perceptible throughout and appeared to become more noticeable with time. Bloody wounds and scar formation were observed through at least observation day 9. Therefore the test substance is considered highly irritating to the skin of rabbits.
For eyes, the eyes of six rabbits were treated with the test substance and observed for six days. Results indicate that the substance was moderately irritating but because of the intensity of the necrosis formation the study was stopped at day 6.
Effects on skin irritation/corrosion: highly irritating
Effects on eye irritation: moderately irritating
