EC number: 266-028-2
CAS number: 65996-93-2
The residue from the distillation of high temperature coal tar. A black solid with an approximate softening point from 30°C to 180°C (86°F to 356°F). Composed primarily of a complex mixture of three or more membered condensed ring aromatic hydrocarbons.
No particular irritation to skin and eye was noted in experimental standard studies. In the presence of UV-light (UVA), photo-induced human skin irritation was observed under working (bright sunlight) and experimental (artificial UV irradiation) conditions.
No particular irritation to skin and eye was
noted in experimental standard studies.
However, in the presence of UV-light
(UVA), photo-induced human skin irritation was observed under working
and experimental conditions (Crow et al. 1961).Human
exposure to pitch (identity not specified) within a working environment
under bright sunlight resulted in skin irritation. In addition, the same
pitch experimentally applied on the skin of human volunteers as
chloroform solution caused pronounced skin irritation after radiation
with UV-light (UVA).The composition of
the pitch utilised may be somewhat different from the registration
substance due to differences in production conditions and distillation
temperature. Basic constituents and consequentially basic effects will
be the same for both substances. Thus, it is justified to use this study
(Crow et al 1961) to indicate possible irritation effects of coal tar
pitch, high temp. under UV-light irradiation.
No irritating effects have been observed after exposure to pitch,
coal tar, high-temp. under standard test conditions. Classification for
irritation/corrosion is not required.
Potential UV-light induced skin irritating effects (see above) are
not taken into account for classification as conditions causing this
effect do not correlate to standard test procedures.
