- 1-chloro-1,1-difluoroethane is identified as:
"Dangerous
for the ozone layer."
The report, entitled Examples
of substances requiring particular attention, was
issued by the Swedish National Chemicals Inspectorate in collaboration
with the Swedish Environmental Protection Agency and the Swedish
National Board of Occupational Safety and Health. NATIONAL CHEMICALS
INSPECTORATE. Order No 510 622. Second, revised edition, 1998.

EPA List of Inerts. This substance
is on List
2
Note:
US EPA allows so-called "Inert" ingredients to be commonly
mixed with the "active" pesticidal ingredient to
create a formulated pesticide product. According
to EPA, "The term `inert' is not intended to imply
nontoxicity; the ingredient may or may not be chemically active."
"Inert" ingredients include solvents, emulsifiers,
spreaders, and other substances mixed into pesticide products
to increase the effectiveness of the active ingredients, make
the product easier to apply, or to allow several active ingredients
to mix in one solution. Both US EPA and California Department
of Pesticide Regulation require pesticide manufacturers to
identify inert ingredients in their products but do not disclose
this information to the general public because the pesticide
industry considers product formulations trade secrets, protected
by law and by the US EPA. The US EPA category of Inerts (as
of September 2003):
List 1 - Of Toxicological
Concern
List 2 -
Potentially Toxic / High Priority for Testing
List
3 - Of Unknown Toxicity
List 4A - Generally Regarded as Safe
List 4B - EPA states it has Sufficient Information to Reasonably
Conclude that the Current Use Pattern in Pesticide Products
will not Adversely Affect Public Health or the Environment
