A.I.S.E. / CESIO in vitro program
ERASM EDI project to address concentration related effects (SCL)
with pure and diluted surfactants for eye damage/irritation
Main project objectives:
– Develop an in vitro test strategy to set specific concentration
limits for surfactants.
– Develop a method to allow classification as Category 2 based
on in vitro data.
On-going activities
