Description of key information

Additional information

Several studies on ready biodegradability of tertiary butyl alcohol have been conducted with results varying from little or no degradation to 99% degradation. A subsequent inherent biodegradability study designed to prevent test material loss from volatilisation and using adapted inoculum proved that tertiary butyl alcohol is inherently biodegradable
