Endpoint conclusion
Endpoint conclusion:
no adverse effect observed (not sensitising)
Additional information:

In a dermal sensitization study (Manciaux, 1999) with Esterol C (batch No. 99.06.501) in corn oil, Hartley guinea-pigs were tested using the method of Guinea pig maximisation test. No clinical signs and no deaths were noted during the study. No cutaneous reactions were observed after the challenge application. Under the experimental conditions of the study, Esterol C does not induce delayed contact hypersensitivity in guinea pig.

Many other studies on different members of the category are reported in secondary literature and they are all negative. It can be concluded that no concern is raised for sensitisation of fatty acid C16 -C18 and C18 insatd. methyl esters.
