SECTION 6 TOXICOLOGY INFORMATION
{ CONTINUED )
COMMENTS: Redness, swelling, and blanching of the skin were noted. Scab formation was due to the corrosive action of the product. However, no systemic signs of toxicity were observed.
SKIN SENSITIZATION: Cyclohexylamine can cause sensitization in susceptible individuals.
* * *
*
PRIMARY EYE IRRITATION TEST (ALBINO RABBITS):
*
EYE IRRITATION INDEX DRAIZE RATING: Corrosive
*
COMMENTS: Severe redness, swelling, and blistering of the conjunctiva were observed. Opacification of the cornea was also noted. Due to the extreme corrosive action of the test material, no Draize index rating could be assigned.
*
*
OTHER TOXICITY RESULTS: Cyclohexylamine. A battery of tests including the
*
Ames test, sister chromatid exchange, cell transformation, mouse lymphoma and *
rat hepatocyte/DNA repair provided inconclusive evidence of mutagenic activity.*
