Cypermethrin 169 CYPERMETHRINS (118) INCLUDES CYPERMETHRIN (118), ALPHA-CYPERMETHRIN AND ZETA-CYPERMETHRIN RESIDUE AND ANALYTICAL ASPECTS Cypermethrin was first evaluated by the 1979 JMPR and a number of times subsequently. It was reviewed for toxicology by the 2006 JMPR within the periodic review programme of the CCPR; the review included alpha-cypermethrin and zeta-cypermethrin, which had not previously been considered by the JMPR. The periodic review for residues was scheduled for 2008. CCPR, at its 39th Session in 2007, noted that three manufacturers would submit residue data to JMPR on CYPERMETHRINS (including alpha and zeta cypermethrin) for consideration by the 2008 JMPR.
Cypermethrin 171 DCVA and 3-phenoxybenzoic acid (and related degradation products) were identified in the residue as well as 4'-hydroxy-cypermethrin and cyperamide (-CN converted to –CONH2).
