Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information

The biodegradation is the biologically mediated degradation or transformation of chemicals usually carried out by microorganisms; Lysozyme is an enzyme, i.e. biological material and therefore it can be considered ready biodegradable.

Nevertheless, lysozyme, as enzyme, is a protein class; the general degradation pathway of proteins is a stepwise process starting with the splitting of peptide bonds in the protein polymer by proteolytic enzymes (proteases) forming lower-molecular oligopeptides, which are subsequently degraded by peptidases to the monomeric amino acids.

In some cases enzymes that are derived from new technologies might have increased stability and therefore altered biodegradability potential; nevertheless, this is not the case for the lysozyme hydrochloride. Lysozyme hydrochloride preserves the functionality and the reactivity potential of the precursor lysozyme, thus the substance characterization is not significantly altered and the environmental fate and pathway is not significantly impacted.

There are no specific data about the anaerobic biodegradation potential of lysozyme hydrochloride.
