Endpoint summary
Administrative data
Description of key information
Adsorption/desorption
The Koc value estimated by using structure estimation for chemical 4-Nonylphenol, ethoxylated (CAS no. 26027-38-3) method is 1300 and log Koc is 3.1139 (HSDB, 2017). This value indicate that this chemical has moderate sorption to soils and sediments, and slow migration potential to ground water.
Additional information
Adsorption/desorption
Various experimental and predicted data for the target compound 4-Nonylphenol, ethoxylated (CAS No. 26027-38-3) and supporting studies for its read across substance were reviewed for the adsorption end point which are summarized as below:
In a key study fromauthoritative database (HSDB, 2017),the Koc value estimated by using structure estimation for test chemical 4-Nonylphenol, ethoxylated (CAS no. 26027-38-3) method is 1300 and log Koc is 3.1139.
In aprediction done using theKOCWIN Program (v2.00) of Estimation Programs Interface (EPI Suite, 2017) was used to predict the soil adsorption coefficient i.e Koc value of test chemical 4-Nonylphenol, ethoxylated (CAS No. 26027 -38 -3). The estimated soil adsorption coefficient i.e Koc value of 4-Nonylphenol, ethoxylated was estimated to be 1335 L/kg (log Koc=3.1255) by means of MCI method (at 25 deg C).
For the read across chemical sodium 2-[2-(dodecyloxy)ethoxy]ethyl sulfate (CAS no. 3088-31-1), the Koc value estimated (HSDB, 2017) by using structure estimation method based on molecular connectivity indices for the read across substance sodium 2-[2-(dodecyloxy)ethoxy]ethyl sulfate is 1200 and log Koc is 3.0791.
On the basis of above results for target chemical 4-Nonylphenol, ethoxylated(from authoritative database HSDB and EPI suite, 2017) and for its read across substance from authoritative database HSDB, it can be concluded that the Koc value of test substance4-Nonylphenol, ethoxylated ranges from 1300 – 1335 indicating that the chemical 4-Nonylphenol, ethoxylatedhas amoderate sorption to soils and sediments, and slow migration potential to ground water.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
