Description of key information
Short description of key information on bioaccumulation potential result:
The evaluation of toxic-kinetic properties of the substance. Dusantox L is viscious liquid, dark-brown colour,with characteristic aromatic smell. It is the mixture of Dusantox 6PPD and cumyl derivates of Dusantox 6PPD.
Key value for chemical safety assessment
Additional information
The complete toxicological profile of the substance cannot
be relevantly assessed.
The study was performed in two experiments.
In experiment I, Dusantox L was orally administered to the
animals and the parent compound and the metabolites were
analysed by HPLC and LC-MS.
In experiment II Dusantox L spiked with 14C -Dusantox 6PPD
was administered and the distribution of 14C Dusantox 6PPD
in biological materials (plasma, bile, urine and faeces) was
studied by TLC followed by radiometry.
As only one of the components was radio labelled, the
toxicokinetic information is available only for that
component (6PPD). Very limited toxico-kinetic data for the
second component are presented.
Identification of metabolites in biological samples is
missing. For the HPLC method with MS/UV detection no
detection and quantification limits are given. The
justification by an inadequately sensitive detector is
understandable but not acceptable.
Identification of metabolites based on the mass spectra
would be very important as there is a possibility of
degradation to primary and secondary amines, which can react
in vivo to form nitrosamines.
The evaluation of toxic-kinetic properties of the substance.
Dusantox L is viscious liquid, dark-brown colour,with
characteristic aromatic smell. It is the mixture of cumyl
derivates of Dusantox 6PPD which is the main component of
the product with alphamethylstyrene.
At the evaluation of the properties of the chemical
substance the tests were done from the point of view of :
a)physico-chemical properties (A1, A2, A3, A4, A5, A6,
A6.1,A8.1, A9, A15, A19) and for Dusantox L resulted :
- freezing temperature : -12-C
- boiling range starts at approx. 141- and ends at 466-C
- relative density : 1,0269 kg.m-3 at 20-C
- well soluble in acetone, toluene and methanol
- water solubility < 0,001g/l at 20-C
- flash-point : 164,5-C
- without explosive and oxidizing properties
- auto-ignition temperature : 520-C
- there is no reaction between the substance and the water,
the substance is undissolved in water
- partition coefficient (n-octanol/water) : log Pow is 4,6
(6PPD) and log Pow is 6,5 (cumylderivate).
b) toxicologic properties (B1, B3, B4, B5, B6, B7, B10,
B12,B14) and for Dusantox L is resulted :
- oral toxicity - after one-shot peroral application the
irreparabil changes in the organism do not be registered -
after 14-days testing period - without toxic effects at the
defined value >2000 mg/kg of live weight, it means the
substance is not toxic.
- dermal toxicity - the test of acute dermal toxicity with
the limit test after 14-days testing period for the rat
LD50 >2000 mg/kg of live weight. For the both sexes of
testing animals - LD50 >2037 mg/kg, it means without the
symptomps of intoxication.
- dermal irritation - the mild irritation for the rabbit
skin with irritation index IKI=1,16, was shown by the test
of the acute dermal irritation, it means the substance is
mild irritating.
- eye irritation - the acute index of the eye irritation
IOI=4, it means the substance is not irritating for the eyes.
-dermal senzibility - the maximizable test for the dermal
senzitizing potential for albinotic hamsters with the
positive dermal reaction of 35% from the 20 of
experimental animals, it means Dusantox L is the mid-strong allergen.
- subacute oral toxicity - 28-days repeated application for
the rats. The dose of 40 mg/kg - without harmful effects
(NOAEL). The dose 80 mg/kg - mild reversible health
troubles.At the dose of 120 mg/kg - the big exposure of health troubles.
-mutagenity test -in vitro ( mammalian chromosome
aberration test in chinese hamster lug cells) - after the
test of tribal cells of chinese hamsters fibroblastes, the
result - the substance is clastogenic. Post control test -
bacterial test of reverse mutations at the organism of
Salmonella typhimurium for 4 indication trunks in the dose
0,01; 0,05; 0,1; 0,25 at 0,5 volume % of the basic sample in
the doses 0,1 ml to the boat.The experimets without
metabolic activation and with metabolic activation trough
the supernatante of rat liver homogenates and by the mix of
co-factors - the result is negative.
- mutagenity test -in vivo test of erythrocyte at the rats
of the both sexes with the dose of 1000 mg/kg live weight -
the result was negative.
c)ecotoxicologic properties (C1, C2, C3, C4.C, C7, C11) and for Dusantox L is resulted :
- acute fish toxicity test - semi-static test of the acute lethal toxicity for Cyprinus carpio in fresh water with the
result LC50(96h) = 1 mg/l, it means Dusantox L is hardly decomposable and toxic for envinonment.
- acute immobilisation test and reproduction test with Daphnia magna in fresh water with the result of decrease
more than 2,3 mg/l per 24 hours and ca. 1,3 mg/l per 48 hours, it meas Dusantox L is toxic for environment.
- toxicity for the qrowth of the green algae - algal Scenedesmus subspicatus growth inhibition test - the grouth
does not be effected by pH -increasing.
- biodegradability - determination of biodegradability in the modified Sturm test - degradation of 46% in the course
of 28 days, it means Dusantox L is not readily biodegradable.
- solubility in water - hydrolysis test as at function of pH - not measurable because of poor solubility in aqueous buffer.
