Description of key information
Adsorption/desorption:
The Soil Adsorption Coefficient i.e. Koc value of test chemical Xanthylium, 9-[2-(ethoxycarbonyl)phenyl]-3,6-bis(ethylamino)-2,7-dimethyl-, molybdatesilicate (CAS No. 63022-06-0) was estimated using EPI suite KOCWIN Program (v2.00) as 16080000 L/kg (log Koc= 7.2062) by means of MCI method at 25 deg. C. This log Koc value indicates that test chemical Xanthylium, 9-[2-(ethoxycarbonyl)phenyl]-3,6-bis(ethylamino)-2,7-dimethyl-, molybdatesilicate has very strong sorption to soil and therefore have negligible migration potential to ground water.
Additional information
Adsorption/desorption:
Results of two different predicted data for the target compound of Xanthylium, 9-[2-(ethoxycarbonyl)phenyl]-3,6-bis(ethylamino)-2,7-dimethyl-, molybdatesilicate (CAS No. 63022-06-0) were reviewed for the Adsorption end points which are summarized as below.
The Soil Adsorption Coefficient i.e. Koc value of test chemical Xanthylium, 9-[2-(ethoxycarbonyl)phenyl]-3,6-bis(ethylamino)-2,7-dimethyl-, molybdatesilicate (CAS No. 63022-06-0) was estimated using EPI suite KOCWIN Program (v2.00) as 16080000 L/kg (log Koc= 7.2062) by means of MCI method at 25 deg. C. This log Koc value indicates that test chemical Xanthylium, 9-[2-(ethoxycarbonyl)phenyl]-3,6-bis(ethylamino)-2,7-dimethyl-, molybdatesilicate has very strong sorption to soil and therefore have negligible migration potential to ground water.
Another supporting study was done by using Chemspider-ACD/Phy chem suite of Royal Society of Chemistry, 2017 the soil adsorption co-efficient i.e., Koc value of test substance Xanthylium, 9-[2-(ethoxycarbonyl)phenyl]-3,6-bis(ethylamino)-2,7-dimethyl-, molybdatesilicate (CAS no. 63022-06-0) was estimated to be 1148.83 dimensionless (log Koc= 3.060) at pH 5.5 and 5626.57 dimensionless (log koc= 3.7502) at 7.4 and temperature 25 deg.C Based on log koc value at pH 7.4 indicates that the chemical Xanthylium, 9-[2-(ethoxycarbonyl)phenyl]-3,6-bis(ethylamino)-2,7-dimethyl-, molybdatesilicate has strong sorption to soil and sediments therefore negligible to slow migration potential to ground water.
On the basis of above results for target chemical Xanthylium, 9-[2-(ethoxycarbonyl)phenyl]-3,6-bis(ethylamino)-2,7-dimethyl-, molybdatesilicate (CAS No. 63022-06-0) from EPI suite and Chemspider, 2017) it can be concluded that the log Koc value of test substance Xanthylium, 9-[2-(ethoxycarbonyl)phenyl]-3,6-bis(ethylamino)-2,7-dimethyl-, molybdatesilicate ranges from 3.7502 to 7.2062 indicating that the chemical has very strong sorption to soil and sediment and therefore have negligible to slow migration potential to ground water.
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.
