Description of key information
The partition coefficient n-octanol/water (log Pow) of ITC 826 Concentrate was determined according to the EEC Directive 92/69, part A.8, to the OECD Guidelines 107 (GLP).
The partition coefficient of ITC 826 Concentrate was estimated to be = -1.70 using the ratio of the solubility data in n-octanol and in water.
Based on this result, ITC 826 Concentrate is considered to have a low potential of bioaccumulation.
Key value for chemical safety assessment
- Log Kow (Log Pow):
- -1.7
- at the temperature of:
- 25 °C
Additional information
It is proposed to use this data for the assessment of the bioaccumulation potential for Perform STi. The main assumption to justify the read-across approach is that both substances have a similar chemical structure.
Both substances are Perform STi, one being a Tetrakis-hydroxymethylphosphonium chloride (THPC), urea and 1-tetradecylamine (C14 amine), and the second one being a ITC 826 (i.e. Tetrakis-hydroxymethylphosphonium chloride (THPC), urea and 1-tetradecylamine (C16 – C18 amine).
Therefore, both substances have the same functional groups in their chemical structure, and the addition of an alkyl (ethyl to butyl) for ITC 826 Concentrate compared to Perform STi is not expected to have a significant impact on the biological and physico-chemical properties of the substance.
In conclusion, based on the LogKow measured for ITC 826 Concentrate, the registered reaction product is not expected to have bioaccumulation potential.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
