Description of key information
THis substance gave a positive result (>60% degradation relative to the ThCO2 value) with a maximum of 85% recorded on day 29. It may therefore, be concluded that there is a potential for biodegradation under environmental conditions.
The test protocol requires that a 10 day window is applied to the degradation results (60% degradation to be reached within 10 days of 10% of the theoretical carbon dioxide produced).
10% degradation was achieved between day 2 and day 5, and 60% was reached by day 9, ColaTeric LAB-70UP therefore achieved the 10-day window.
The mean result of duplicate testing for biodegradability by OECD 301B (CO2 evolution test) is 60% biodegraded at 9 days, and 85% biodegraded at 29 days.
The final conclusion of this study is therefore that lauryl betaine is readily biodegradable in an aerobic aqueous environment.
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
