Description of key information
Adsorption / desorption
The Soil Adsorption Coefficient i.e Koc value of test substance 1-methyl-3-phenylpropylamine (CAS no. 22374 -89 -6) was estimated using Adsorption Coefficient module program as Koc 1, 1.13, 8.52, 68.6, 254, 349, 362 and 364 at pH range 1-7, 8, 9, 10, 11, 12, 13 and 14 respectively (log Koc value ranges from 0 to 2.6 ± 1.0). The Koc value (at pH 7.0) indicates that the substance 1-methyl-3-phenylpropylamine has a negligible sorption to soil and sediment and therefore have rapid migration potential to ground water.
Additional information
Adsorption / desorption
Various predicted data for the target compound 1-methyl-3-phenylpropylamine (CAS No. 22374-89-6) were reviewed for the adsorption end point which are summarized as below:
The Soil Adsorption Coefficient i.e Koc value of test substance 1-methyl-3-phenylpropylamine (CAS no. 22374 -89 -6) was estimated using Adsorption Coefficient module program as Koc 1, 1.13, 8.52, 68.6, 254, 349, 362 and 364 at pH range 1-7, 8, 9, 10, 11, 12, 13 and 14 respectively (log Koc value ranges from 0 to 2.6 ± 1.0)(2017). The Koc value (at pH 7.0) indicates that the substance 1-methyl-3-phenylpropylamine has a negligible sorption to soil and sediment and therefore have rapid migration potential to ground water.
In an another prediction done by using ChemSpider Database (2017),the Soil Adsorption Coefficient i.e Koc value of test substance 1-methyl-3-phenylpropylamine (CAS no. 22374 -89 -6) was estimated. The adsorption coefficient (Koc) value of test substance 1-methyl-3-phenylpropylamine was estimated to be 1 (Log Koc = 0) at both pH 5.5 and 7.4, respectively. This Koc value indicates that the substance 1-methyl-3-phenylpropylamine has a negligible sorption to soil and sediment and therefore have rapid migration potential to ground water.
Additional soil adsorption coefficient i.e Koc value of test chemical1-methyl-3-phenylpropylamine (CAS No. 22374 -89 -6) was estimated using the SciFinder database (2017).The soil adsorption coefficient i.e Koc value of 1-methyl-3-phenylpropylamine was estimated to be 1, 1.26, 9.50 and 76.6 at pH range 1-7, 8, 9 & 10, respectively (at 25 deg C) (log Koc value ranges from 0 to 1.884). The Koc value (at pH 7.0) indicates that the substance 1-methyl-3-phenylpropylamine has a negligible sorption to soil and sediment and therefore have rapid migration potential to ground water.
On the basis of above overall results for target chemical1-methyl-3-phenylpropylamine (from modelling databases,2017), it can be concluded that the Koc value of test substance 1 -methyl-3 -phenylpropylamine was estimated to be 1 (Log Koc = 0) (at pH 7.0) indicating that the test chemical 1 -methyl-3 -phenylpropylamine has a negligible sorption to soil and sediment and therefore have rapid 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).
