Re: 2,2,4 trimethylpentane (Isopar C) - usage and health & safety information

Subject:  Re: 2,2,4 trimethylpentane (Isopar C) - usage and health & safety

The Scorecard (http://www.scorecard.org), an Internet database on toxic
chemicals, chemical releases, and other
environmental health hazards, has a listing on the chemical you are asking
about at the url below:
You can use Scorecard's "About the Chemicals" feature to find heath and use
 information on
thousands of toxic chemicals.  Just an fyi!

Subject:  2,2,4 trimethylpentane (Isopar C) - usage and health & safety

   I am researching usage and health & saftey information on thirty
chemicals (HAPs).  2,2,4 trimethylpentane (aka iso-octane and a key
component in Isopar C) is one of those chemicals.  This information will be
placed on IDEM's ToxWatch page which will include air monitoring data from
eighty-seven chemicals (thirty HAPs are a subset of this list) in four
Indiana counties.
   From my research into Exxon products, Isopar C is used in lithographic
inks and possibly as a cleaning agent.  What is the current usage of this
chemical?  How wide spread is the use of this chemical?  What are effective
substitutes (if any)?  Please relate any other experiences you might have
had with using this material.
   Additionally, it is my understanding that Isopar C/2,2,4
trimethylpentane might be found in pesticide formulations.  Is this true?
If yes, what formulations?  Who would manufacture the pesticide formulation
so I could obtain more information on proper usage?
   Some of the other Isopar formulations are used in every day consumer
products (deodorizers, cleaning agents, etc.).  Does anyone know of the use
of Isopar C/2,2,4 trimethylpentane in any consumer product?  I would doubt
it, but I want to check anyway.  It would be quite ironic to monitor a HAP
from an industrial source where a HAP may be emitted in greater
concentration in someone's home.
   I thank you for your assistance in this effort!
