Administrative data
- Endpoint:
- additional toxicological information
- Adequacy of study:
- weight of evidence
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: see 'Remark'
- Remarks:
- Scientifically acceptable. Update of earlier (1980) Safety Assessment. Special emphasis on potential reactions with other ingredients, i.e. triethanolamine, which might lead to nitroso compounds, and toxicological findings related to such nitroso compounds.

Results and discussion
Any other information on results incl. tables
Twenty out of fifty bronopol exposed workers suffered from skin irritation and/or superficial burns. In 8 cases a second occurrence, in 6 cases, a third occurrence and in 3 cases, a fourth occurrence were reported. The reported findings were described as irritant reaction rather than contact allergy.
The earlier conclusion is reaffirmed that Bronopol is safe as a cosmetic ingredient at concentrations up to 0.1% except from circumstances where reactions with amines or amides can result in nitrosamine or nitrosamide formation.
Applicant's summary and conclusion
- Conclusions:
- The earlier conclusion is reaffirmed that Bronopol is safe as a cosmetic ingredient at concentrations up to 0.1% except from circumstances where reactions with amines or amides can result in nitrosamine or nitrosamide formation.
- Executive summary:
In a safety assessment (Anonymous, 1984), data on occupational exposure of 50 workers to Bronopol were reported.The skin of 20/50 Bronopol exposed workers showed signs of skin irritation and/or superficial burns following exposure to saturated aqueous solutions or powder of Bronopol on at least one occasion. In 8 cases a second occurrence, in 6 cases, a third occurrence and in 3 cases, a fourth occurrence were reported. None of the concerned workers had quit the job because of these injuries. Conclusively, the reported findings were described as irritant reaction rather than contact allergy.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
