Primary biodegradation definition
Primary biodegradation means the structural change (transformation) of a surfactant by micro- organisms resulting in the loss of its surface-active properties due to the degradation of the parent substance and consequential loss of the surface-active property as measured by test methods listed in Annex II of the consolidated version of Regulation (EC) No 648/2004.
