The study w2,s performed on Octo6er the 21st and the 22nd 1992, accordi:~g 

to the experimental protocol deseribed below ; 

3.1. PRItiCIPLE 

:'he technique zs proposed as an alternative to the 'JRr1TZE test End allows 

to assess the irritancy power of a product after singie application on 

the chorzoallantoic membrane of tlze hen's egg.
