TOXICOLOGICAL INFORMATION

ANIMAL ROUTES COMPONENTS
>7,940 mg/kg Rabbit Acute Dermal Phenol, 4,4'-butylidenebis [2-(1,1-dimethylethyl)- 5-methyl-]
> 7,940 mg/kg Rat Acute Oral Phenol, 4,4'-butylidenebis [2-(1,1-dimethylethyl)-5-methyl-]
Toxicological Information:
The toxicological properties of this material have not been fully determined.

An LDLo in rats for this material has been established at 17 g/kg.

The eye irritation data in rabbits has been judged slightly irritating (3 of 110). The skin irritation data in rabbits has been judged non-irritating (0 of 110). A human patch test using 51 subjects did not produce sensitization.

This material did not produce an increase in unscheduled DNA syntheses (UDS) in rat hepatocytes, did not produce chromosomal aberrations in Chinese hamster ovary (CHO) cells in the presence or absence of S-9 metabolic activation, and did not produce mutagenicity in the Ames assay using Salmonella and Saccharomyces indicator organisms either in the presence or absence of metabolic activation.

Dietary levels of 0, 1,000, 2,500, 5,000 or 10,000 ppm administered to male and female rats for 4 weeks produced no deaths or significant clinical signs. Decreased food consumption and body weights were observed at 2,500, 5,000 and 10,000 ppm. Gross histopathological evaluation revealed discolored livers and increased liver weights in both sexes at all dose levels.

Microscopic evaluation revealed hepatocellular vacuolation (lipid accumulation). Hepatocellular necrosis was also observed at the three highest dose levels. A no-observed-effect-level (NOEL) was not identified in this study.

No deaths were observed in a subchronic 90-day feeding study at dose levels of 0, 100, 500 and 1,000 ppm in male and female rats. At the highest dose, reduced body weights, food consumption, altered liver enzyme levels, increased liver weighs, and microscopic liver and lymph node changes were observed. The mid-dose level produced similar changes in serum liver enzyme levels, liver weights, and in live and lymph node tissue. The no-observed-adverse-effect-level (NOAEL) was considered to be 100 ppm.

Other acute and chronic health hazards, as well as target organs, are unknown.
As with all dusts, inhalation of air concentration levels above the PNOR may cause irritation and adverse lung effects.
