Description of key information
Additional information
Butyl glycollate is ready biodegradable under the conditions of the test on ready biodegradability, reaching the 10-day window criterion and ending up in a degradation rate of more than 80% at the end of the test, which can be considered as completely biodegraded. According to Level III Mackay Fugacity Model, the main environmental compartments where butyl glycollate is distributed, are water and soil. The distribution in the sediment fraction is negligible and only a small amount reaches the air. Although the vapour pressure of butyl glycollate is high, and its ability to volatilize from the water fraction is moderate. A relatively high mobility in the soil fraction can be expected, based on the log Koc of 0.66. However, it can be assumed that it is relatively fast degraded during the soil passage.
The atmospheric half-life of butyl glycollate based on the Atkinson calculation is about 5.61 days at 25°C, under annual averaged conditions of the northern hemisphere and assuming a 12-hour day. But due to its low log Koc, a sorption to particles in the air is unlikely, indicating a low potential for long-range transport.
In the biotic compartments of the environment, a bioaccumulation of butyl glycollate cannot be assumed. The low log Pow of 0.38 would result in a low BCF value and a low potential for bioaccumulation.
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.
