Description of key information

The substance is a reaction mass of N-glycyl-L-tyrosine hydrochloride and potassium chloride. As the individual components have different logKow values the results for the the relevant components are presented rather that the mixture being treated as a single component.

The only relevant organic compounds of the substance are N-glycyl-L-tyrosine (typical concentration of N-glycyl-L-tyrosine hydrochloride: 39%) and glycine (typical concentration of glycine: 3%).

The partition coefficient of the substance N-glycl-L-tyrosine was calculated with a valid QSAR modell (KOWWIN). The resulting logKow is -0.45

The partition coefficient of the substance glycine was retrieved from peer-reviewed handbook data. The resulting logKow is -3.21

The worst case value was determined as key value for chemical safety assessment.
