Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Additional information
ABIOTIC DEGRADATION INAIR
DIRECT
PHOTOLYSIS in air
Sodium
cocoyl glycinate (SCG) 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 cocoyl glycinate (SCG) can be estimated with US EPA AOPWIN Program resulting in a low degradation half-life of 0.3d (12h day). But as Sodium cocoyl glycinate (SCG) 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 of Sodium cocoyl glycinate (SCG) cannot be hydrolyzed rapidly under environmental conditions as stated in OECD Guideline 111. In addition SCG is readily biodegradable.

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