Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

ABIOTIC DEGRADATION INAIR


 


DIRECT PHOTOLYSIS in air
Sodium Lauroyl glycinate (SLG) does not absorb light >290 nm (ozone band) and therefore a direct photolysis in air will not occur.


INDIRECT PHOTOLYSIS in air


OH radical induced indirect photolysis of Sodium Lauroyl glycinate (SLG) can be estimated with US EPA AOPWIN Program resulting in a low degradation half-life of 0.3d (12h day). But as Sodium Lauroyl glycinate (SLG) has a low Henry’s Law Constant of  8*10-14 Pa*m3/mole, volatilisation is not an exposure route which has to be considered. 


 


ABIOTIC DEGRADATION IN WATER



HYDROLYSIS


The amide group ofSodium Lauroyl glycinate (SLG) cannot be hydrolyzed rapidly under environmental conditions as stated in OECD Guideline 111. In addition SLG is readily biodegradable.


 


DIRECT PHOTOLYSIS in water
Sodium Lauroyl glycinate (SLG) does not absorb light >290 nm (ozone band) and therefore a direct photolysis in water will not occur


INDIRECT PHOTOLYSIS in water


OH radical induced indirect photolysis of SSodium Lauroyl glycinate (SLG) can be estimated with US EPA AOPWIN Program resulting in a low degradation half-life of 0.3d (12h day). Sodium Lauroyl glycinate (SLG) may therefore be degraded in water by indirect photolysis if sufficient OH radicals are available. As SLG is rapidly biodegraded in surface water (see IUCLID Section 5.2.2) indirect photolysis will play a minor role in degradation.


 


ABIOTIC DEGRADATION IN SOIL


 


DIRECT PHOTOLYSIS in soil


Sodium Lauroyl glycinate (SLG) does not absorb light >290 nm (ozone band) and therefore a direct photolysis in soil will not occur.


INDIRECT PHOTOLYSIS in soil


OH radical induced indirect photolysis of Sodium Lauroyl glycinate (SLG) can be estimated with US EPA AOPWIN Program resulting in a low degradation half-life of 0.3d (12h day). Sodium Lauroyl glycinate (SLG) may therefore be degraded in soil by indirect photolysis if sufficient OH radicals are available. As SLG is rapidly biodegraded in aerobic soils (see IUCLID Section 5.2.3) indirect photolysis will play a minor role in degradation.
