Results and discussion
Toxicokinetic / pharmacokinetic studies
- Details on absorption:
- The majority (>90% )of the orally administered dose was excreted very likely unabsorbed via the faeces. From the amount excreted in urine (<3%) and tissue residues (<1%), the report authors concluded that the oral absorption was <10%.
- Details on excretion:
- Excretion primarily via feces (89-99%) and urine (2.5%); an insignificant amount was expired.
Metabolite characterisation studies
- Details on metabolites:
- The majority (>90% )of the orally administered dose was excreted very likely unabsorbed via the faeces. From the amount excreted in urine (<3%) and tissue residues (<1%), the report authors concluded that the oral absorption was <10%.
Excretion primarily via feces (89-99%) and urine (2.5%); an insignificant amount was expired.
Metabolites were characterised from dose group c) using TLC, HPLC and MS. Females metabolised the parent compound more than males. Metabolism, which may be by microbial activity, comprised the oxidation of the two decyl side chains to form hydroxy and hydroxyketo derivatives; metabolism of methyl side chains was not found.
Applicant's summary and conclusion
- Conclusions:
- In a toxicokinetic study, rats received a single oral gavage dose of 14C-labelled didecyldimethyl ammonium chloride. The majority (>90% )of the administered dose was excreted via the faeces. From the amount excreted in urine (<3%) and tissue residues (<1%), the report authors concluded that the oral absorption was less than 10%.
Under the test conditions, the test material (containing carbon 14 labelled DDAC) showed a low absorption after oral administration. It is excreted in the urine and faeces and a negligible amount is retained in the body after 1 wk
