Endpoint summary
Administrative data
Description of key information
No in vitro skin sensitisation studies or in vivo murine LLNA were identified, or are required, as a reliable in vivo guinea pig study is already available.
The skin sensitisation potential of Anthemis nobilis, ext., (Chamomile oil) was assessed in guinea pigs in an in vivo open epicutaneous test. 0.1 mL of the test material (as a 4% solution) was applied to clipped skin on one flank of each of 6 guinea pigs, daily for 21 days. A challenge application was made on the contralateral flank on days 21 and 25. Anthemis nobilis, ext., (Chamomile oil) was not sensitising to the skin of guinea pigs in this study (Klecak, 1985).
No respiratory tract sensitisation data are available.

Skin sensitisation
Link to relevant study records
- Endpoint:
- skin sensitisation: in vivo (non-LLNA)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 1985
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:

- Principles of method if other than guideline:
- Open Epicutaneous Test: the test material was applied to 6 guinea pigs (males and females) on an 8 cm2 area of clipped flank skin, daily for 3 weeks. The test site remained uncovered. Reactions were scored at the end of the application period or the end of each week. The challenge was applied in the same way on the contralateral flank, on days 21 and 25 of the study. 10 guinea pigs served as controls.

- Executive summary:
The skin sensitisation potential of Anthemis nobilis, ext., (Chamomile oil) was assessed in guinea pigs in an open epicutaneous test. 0.1 mL of the test material (as a 4% solution) was applied to clipped skin on one flank of each of 6 guinea pigs, daily for 21 days. A challenge application was made on the contralateral flank on days 21 and 25. Anthemis nobilis, ext., (Chamomile oil) was not sensitising to the skin of guinea pigs in this study.
Reference
Endpoint conclusion
- Endpoint conclusion:
- no adverse effect observed (not sensitising)
- Additional information:
A CIR expert review (Johnson et al, 2017) summarised the results of several studies assessing the human skin sensitisation potential of Anthemis nobilis, ext. In a maximization test involving 25 subjects, a 4% solution (in petrolatum) of Anthemis nobilis “flower oil” was not a skin sensitiser. In repeated insult patch tests in humans (HRIPTs), Anthemis nobilis essential oil [concentration unspecified] did not induce skin sensitisation in 104 and 110 patients. A skin care lotion containing 3% Anthemis nobilis “flower oil” was also tested in a HRIPT and found not to have a potential for eliciting dermal sensitisation. Results were negative in 29 patients patch tested with Anthemis nobilis, ext. (1% in petrolatum), while in a provocative patch test, 2 of 14 patients displayed reactions to Anthemis nobilis (again at 1% in petrolatum) that were described as “++”. Allergic dermatitis and other sensitisation reactions to Anthemis nobilis ingredients have been reported in a small number of individual case reports.
Respiratory sensitisation
Endpoint conclusion
- Endpoint conclusion:
- no study available
- Additional information:
No respiratory tract sensitisation data are available. A new study was not conducted as no standard and validated test method is available and it is not a REACH Standard Information Requirement.
Justification for classification or non-classification
Based on the results of the available and reliable in vivo guinea pig study (Klecak, 1985), Anthemis nobilis, ext., (Chamomile oil) does not warrant classification for skin sensitisation, according to EU CLP criteria (EC 1272/2008).
