Coke formed by cooling, to approximately 1500°C, hot acetylene containing split gases from aromatic residual oil produced from ethylene production by naphtha cracking at 800°C to 900°C (427°F to 482°F) (coal derived).
Since irritation data are recommended for a 4 h skin exposition,
results of the available 20 h and the 15 min exposition will serve as
approximation. Descriptive scores of the raw
data have been converted to Draize numerical scores.
This study meets scientific standards with acceptable restrictions
(limited documentation). Skin irritation was tested using an internal
standard method (BASF test). White Vienna rabbits were used. 2 animals
were treated for 1, 5 and 15 minutes and for 20 hours using occlusive
conditions. An application site of 2.5 x 2.5 cm was covered with the
The test substance induced erythema after 20 h occlusive exposure
(reversibel within 7 d) in 1/2 animals; 15 min exposure did not cause
any irritation effects.
Acetylene coke has to be evaluated as minimal irritating to the skin
