Revision Date: 09/23/2003 MSDS : QCHEM0001
lights, welding equipment, and electrical motors and switches.
General Handling Information: Avoid work practices that may release volatile components in the
atmosphere. Local air pollution regulations should be consulted to determine if the release of volatile
components is regulated or restricted in the area in which this material is used. Avoid contaminating soil
or releasing this material into sewage and drainage systems and bodies of water.
Static Hazard: Electrostatic charge may accumulate and create a hazardous condition when handling
this material. To minimize this hazard, bonding and grounding may be necessary but may not, by
themselves, be sufficient. Review all operations, which have the potential of generating an accumulation
of electrostatic charge and/or a flammable atmosphere (including tank and container filling, splash filling,
tank cleaning, sampling, gauging, switch loading, filtering, mixing, agitation, and vacuum truck operations)
and use appropriate mitigating procedures. For more information, refer to OSHA Standard 29 CFR
1910.106, 'Flammable and Combustible Liquids', National Fire Protection Association (NFPA 77),
'Recommended Practice on Static Electricity' (liquids, powders and dusts), and/or the American
Petroleum Institute (API) Recommended Practice 2003, 'Protection Against Ignitions Arising Out of Static,
Lightning, and Stray Currents' (liquids).

Revision Number: 1 1-Hexene (QCHEM)
5of 9
Revision Date: 09/23/2003 MSDS : QCHEM0001
ADDITIONAL TOXICOLOGY INFORMATION:
This product contains 1-HEXENE.
1-Hexene gave negative results in the following mutagenicity assays:
Ovary (CHO) Cell HGPRT Gene Mutation Assay>
Synthesis (UDS) in Rat Primary Hepatocytes Assay>
Mutation Assay>
Assay>
Cells Assay>
BALB/c-3T3 Cells Assay>Results of a reproduction/developmental toxicity screening test of 1-hexene in
rats showed no reproductive or developmental toxicity when tested at 100, 500, and 1000 mg/kg/day
administered by oral gavage. Microscopic kidney changes were seen in males at all dose levels. This
effect is consistent with alpha 2u-globulin associated hydrocarbon nephropathy, which is specific to young
adult male rats and is not considered a potential risk to humans. Results of a 9-day inhalation toxicity
study showed that inhalation of10,000 ppm 1-HEXENE (C6 H12) vapor in air for six hours a day caused
no observable adverse effects in rats. Results of a 90-day inhalation toxicity study showed that inhalation
of up to 3,000 ppm 1-hexene vapor for six hours a day for 13 weeks caused no mortality or clinical signs
of toxicity in rats.
This product contains N-HEXANE.
TARGET ORGAN TOXICITY: Prolonged or repeated ingestion, skin contact or breathing of vapors of n-
hexane has been shown to cause peripheral neuropathy. Recovery ranges from no recovery to complete
recovery depending upon the severity of the nerve damage. Exposure to 1000 ppm n-hexane for 18
hr/day for 61 days has been shown to cause testicular damage in rats. However, when rats were exposed
to higher concentrations for shorter daily periods(10,000 ppm for 6 h/day, 5 days/wk for 13 weeks), no
testicular lesions were seen. CARCINOGENICITY: Chronic exposure to commercial hexane (52% n-
hexane) at a concentration of 9000ppm was not carcingogenic to rats or to male mice, but did result in an
increased incidence of liver tumors in female mice. No carcinogenic effects were observed in female mice
exposed to 900 or 3000 ppm hexane or in male mice. The relevance for humans of these hexane-induced
mouse liver tumors is questionable. GENETIC TOXICITY: n-Hexane caused chromosome aberrations in
bone marrow of rats, but was negative in the AMES and mouse lymphoma tests.
This product contains CYCLOHEXANE.
Cyclohexane primarily affects the central nervous systems of laboratory animals and humans. Acute or
prolonged inhalation of cyclohexane at levels below the recommended exposure limits does not result in
toxic effects while acute exposures to levels above these recommended limits can cause reversible
central nervous system depression. Prolonged exposures of laboratory animals to high levels (up to low
thousands of parts per million) have also caused reversible effects which included hyperactivity,
diminished response to stimuli, and adaptive liver changes while very high levels (high thousands of parts
per million) were fatal. No developmental effects were seen in rats or rabbits following exposures of up to
7000 ppm cyclohexane. No reproductive effects occurred in rats, although postnatal pup growth was
reduced at 7000 ppm in a similar manner as observed in the parental animals. Cyclohexane has not
been shown to be mutagenic in several in vitro and in vivo assays and has not produced tumors in
several dermal application long-term bioassays. Based on these results and the lack of any mutagenic or
genotoxic metabolites, cyclohexane is not expected to be mutagenic or genotoxic. Following dermal
exposure, cyclohexane is rapidly absorbed, metabolized,and excreted.
SECTION 12 ECOLOGICAL INFORMATION
