IDEA - International Dialogue for the Evaluation of Allergens

IDEA events in December 2016: the IDEA Workshop on Pre- and Pro- haptens and the meeting of the IDEA Hydroperoxides TF

Published on 10 October 2016

The 4th IDEA Workshop on pre- and prohaptens will take place on December 13th, 2016 nearby Brussels.

The workshop aims at:

 

1) Presenting the latest results from the IDEA Hydroperoxides TF
As a reminder, the purpose of the IDEA Hydroperoxides Task Force is to provide analytical data in support of interpretation of Patch Test reactions to materials containing the hydroperoxides of limonene and linalool. During the last months, the TF has performed a ring test to better understand the formation of linalool and limonene hydroperoxides within the products and to improve the methodologies to enable the confirmation and quantitative measurement for limonene and linalool hydroperoxides in complex mixtures, including certain types of consumer products. The outcome and the next steps will then be discussed among all the participants to the IDEA workshops on pre- and pro- haptens.


2) Providing a framework, to be incorporated in QRA2, on how to identify and characterise, for risk assessment purposes, the potential of fragrance ingredients to be abiotically and/or biotically converted to reactive forms that induce and/or exacerbate the induction of sensitization.
 

The previous day, on December 12th, the IDEA Hydroperoxides TF will meet to share the latest analytical results of the latest ring test within the members of the task force. This ring test has been performed to better understand the formation of linalool and limonene hydroperoxides within the products and to improve the methodologies to enable the confirmation and quantitative measurement for limonene and linalool hydroperoxides in complex mixtures, including certain types of consumer products.
