Description of key information
Sodium oleylamphopolycarboxy glycinate is an amphoteric surfactant with a very high water solubility of 630 g/L and a low measured octanol water partition coefficient indicating that this substance has a low lipofilicity and related low bioaccumulation potential.
Sodium oleylamphopolycarboxy glycinate was biodegraded by 11% at day 28 in the OECD 301D Closed Bottle test and should therefore not be classified as readily biodegradable. In the prolonged Closed Bottle test sodium oleylamphopolycarboxyglycinate was biodegraded 19% at day 60. The biodegradation curve levels off below 60% biodegradation suggesting partial degradation of the test substance. The lack of complete biodegradation in the Closed Bottle test does not mean that part of the test substance is recalcitrant in nature because the stringency of the test procedures could account for the recalcitrance in the Closed Bottle test.
Sodium oleylamphpolcarboxy glycinate is not susceptible to hydrolysis because it does not contain any hydroysable covalent bonds.Sodium oleylamphopolycarboxy glycinate is a salt with a very low vapour pressure.
A lower decrease of the concentration Sodium oleylamphopolycarboxy glycinate was observed in the algae test in a parallel vessel which was covered with aluminium foil indicating that Sodium oleylamphopolycarboxy glycinate maybe susceptible to photodegradation.
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
