EC number: 218-664-7
CAS number: 2212-81-9
Based on log Kow and on water solubility, it
is assumed that the read-across substance, CAS 25155 -25 -3
is not completely absorbed by
inhalation exposure and that inhalation absorption factor doesn’t exceed
oral absorption factor.
Dermal absorption is supposed very low for
several reasons: i) The substance is dry and practically non soluble in
water (<0.62 mg/l, if water solubility is < 1 mg/l, dermal uptake is
likely to be low); the experimental log Kow is > 5.5 and the calculated
log Kow is 7.3; therefore very few of the substance goes from the
stratum corneum to the epidermidis. ii) The molecular weight is 338.5
g/mol, so not really in favour of dermal absorption (below 100: in
favour of dermal absorption, above 500, not in favour of absorption).
iii) the substance is not a skin irritant, therefore no increase of skin
absorption is expected. Therefore, dermal absorption can be reasonably
estimated to be lower than 10%. No data is available on absorption by
oral route, which is therefore assumed to be 100%.
