EC number: 940-783-4
CAS number: -
There is no information available for the multiconsituent substance itself. For one of the of the two major consituents, 40% is bis(2-chloroethoxy)methane CAS 111 -91 -1 + homologues, adme has been has been studied. These data are included here. Bis(2-chloroethoxy)methaneis rapidly absorbed, distributed and excreted after oral, dermal and IV exposure (Black 2007). Therfore 100% absorprion is assumed as the worst case.
The test substance is not readily biodegradable in the closed bottle test. 111-91-1: The low kow is 1.6 and further bioaccumulation testing is not required. An oral adme study with 111-91-1 shows that the majority was excreted <24 hours in the urine, only 1.5 % remained in the carcass of rats and mice after 72 hours. Therefore the test substance has low bioaccumulation potential.

ADME bis(2-chloroethoxy)methane, CAS 111
concentration was found in the kidneys 15 minutes after doing. A
peak of elimination was observed at or before the 15 minute time
point.In the thymus the 14C concentration increased threefold between 15
minutes and 4 hours and remained constant through 8 hours post
dosing. The majority was excreted <24 hours in the urine, only 1.5 %
remained in the carcass of rats and mice after 72 hours (Black 2007) .
dermal exposure to 10 mg/kg bw total dose absorption ranged from 12% to
18% for rats and 14% to 22% for mice in one study (Black 2007) and in
another study (RTI 2002) it ranged from 33% to 55% for rats and 17% to
25% for mice. These results indicated that rats, but not mice, ingested
a significant amount of bis(2-chloroethoxy)methane from grooming at the
administration site. Most of the absorbed dose was excreted in the
urine. Up to 50% of the total dose volatilized from the skin of some
animals during these 24-hour experiments (Black 2007).
substance was rapidly metabolized after IV administration, within 4
hours after dosing the parent chemical was near the limit of detection
in blood and not detected in urine.The major metabolite (about 40% of
the dose) of BCM in rat and mice was isolated and identified as
thiodiglycolic acid. Thiodiglycolic acid is cleared fairly slowly and is
highly concentrated in the liver (Black 2007).
