Technical Data
ARCONATE?br>
Propylene Carbonate
CAS No. 108-32-7
Description A clear polar solvent having high boiling and flash points, a low order of toxicity and a mild
ether-like odor. It is stable under most conditions and is not hydroscopic or corrosive. is
particularly well suited for applications requiring a water white product or high purity. Examples
would be cosmetics, electronics or where recycling of spent material will occur.
Product Chemical Name Dioxolanone
Identification Chemical Family Organic Carbonate
Other Names 4-methyl-1
3-dioxolan-2-one
Chemical Formula C4H6O3
ARCONATE is a cyclic carbonate that reacts with amines to form carbamates, undergoes hydroxy
alkylation and transesterification. It can be used as an isocyanate and unsaturated polyester resin
cleanup solvent, viscosity reducer in coatings, CO2 extraction solvent, electrolyte in lithium
batteries, polar additive for clay gellants, foundry binder catalyst, and textile dye carrier and
cleaner.

ARCONATE is stable under normal storage conditions. However, in the presence of an acid, base,
metal oxide or salt, propylene carbonate may decompose liberating CO2. These materials will also
decrease thermal stability. In an aqueous solution, the decomposition products would be
propylene glycol and CO2. Either situation could potentially lead to pressure buildup in closed
containers, which may result in the container rupturing. It is therefore suggested that all such
mixtures be tested for shelf life stability.
Propylene Carbonate has a low degree of acute toxicity. Undiluted, it is slightly irritating to skin

and may cause minimal to moderate transient eye irritation. It is approved as an indirect food

additive and used in cosmetics at concentrations up to 5%.
No adverse effects were seen beyond the site of applications in subchronic dermal toxicity studies
in rats or rabbits. Additionally, no signs of toxicity have been seen in repeated inhalation studies
with rats, dogs, and guinea pigs, although some evidence of respiratory irritation has been
reported.
ARCONATE is not subject to the reporting requirements of SARA, Title III Sections 311/312 and 313;
Regulatory
is not a hazardous substance under CERCLA; is not on the HAP's list of the Clean Air Act
Status
Amendments; or subject to California Proposition 65.
ARCONATE is on the U.S. TSCA list and is included in the EEC's EINECS, Canadian DSL and
Australian Chemical Inventories.
