Structural assessment


The substance is a complex UVCB which contains a variety of esters, alcohols, ethers and paraffins.


Different components and functional groups within this substance could undergo a variety of Phase I metabolism reactions, for example oxidation of alcohol groups to aldehydes and/or carboxylic acids, followed by Phase II conjugation reactions. The ester components might also undergo some degree of hydrolysis to the corresponding carboxylic acid and alcohol moieties.


The Molecular Weight of the component substances would indicate that some degree of absorption is possible. Furthermore any hydrolysis of the ester components will create lower MW species which would be more easily absorbed.




The substance is relatively poorly soluble in water (<10.8 mg/l). The Log Pow is high (>7.71, range from 3.79 to > 7.87). The high lipophilicity will tend to limit absorption.



The substance did not give rise to any signs of toxicity in any of the available toxicology studies at doses of up to 2000 mg/kg and hence provides no direct evidence regarding its toxicokinetic behaviour.




Based on the available structural data, phys-chem properties and toxicology data,  it is likely that the substance is very poorly absorbed.
