are no dermal penetration/absorption studies available for Sa 190. Dermal
penetration strongly depends on the molecular weight of a substance and
its lipophilic properties. Typically a molecular weight above 500
prevents a substance from penetrating the skin. The lipophilic
properties of a chemical are indicated by the octanol-water partition
coefficient (log Kow). Substances with a molecular weight
below 500 and log Kowvalues between +1.0 and +4.0 are assumed
to be able to penetrate the skin. Log Kowvalues below +1.0 or
above +4.0 indicate decreasing penetration ability while log Kowvalues
below -1.0 or above +6.0 suggests that a substance is not likely to
penetrate the skin*.
Sa 190 has
a molecular weight of 423.72 and a log Pow of >5.7. According to this
data it must be considered that Sa 190 might be able to penetrate the
skin, though to a limited extent. There is no information available to
predict the fate of Sa 190 after dermal penetration. However, taking
into account its physico-chemical properties it is likely to become
degraded by releasing its starting monomers.
