The following results are for the product, unless otherwise indicated.
ACUTE DERMAL TOXICITY :
Species: Rabbit
LD50: > 1,000 mg/kg
Test Descriptor: Product
SENSITIZATION :
This product is not expected to be a sensitizer.6 / 11CHRONIC TOXICITY DATA :
The principal health effects following acute exposure to 2-butoxyethanol are irritation of the eyes and respiratory
tract. 2-butoxyethanol is readily absorbed through the skin. In laboratory animals exposed to 2-butoxyethanol via
inhalation, blood(hemolysis) and secondary effects on the kidney and liver have been observed. When 2-
butoxyethaol is ingested it is metabolized to butoxyacetic acid (BAA), which can cause hemolysis. BAA is rapidly
excreted in urine in animals and humans with an urinary excretion half-life of approximately 3-6 hours in humans.
Human red blood cells have been shown to be significantly less sensitive to hemolysis than those of rodents and
rabbits. These effects are transient and when exposure is discontinued, these effects subside. 2-butoxyethanol does
not cause adverse reproductive or birth effects in animals, unless exposures occur at levels high enough to induce
significant maternal toxicity.
CARCINOGENICITY :
None of the substances in this product are listed as carcinogens by the International Agency for Research on Cancer (IARC), the National Toxicology Program (NTP) or the American Conference of Governmental Industrial Hygienists (ACGIH).

The environmental fate was estimated using a level III fugacity model embedded in the EPI (estimation program interface) Suite TM, provided by the US EPA. The model assumes a steady state condition between the total input and output. The level III model does not require equilibrium between the defined media. The information provided is intended to give the user a general estimate of the environmental fate of this product under the defined conditions of the models. If released into the environment this material is expected to distribute to the air, water and soil/sediment in the approximate respective percentages; Air Water Soil/Sediment <5% 10 - 30% 70 - 90%
The portion in water is expected to be soluble or dispersible.
BIOACCUMULATION POTENTIAL
Based on a review of the individual components, utilizing U.S. EPA models, this material is not expected to bioaccumulate.
ENVIRONMENTAL HAZARD AND EXPOSURE CHARACTERIZATION
Based on our hazard characterization, the potential environmental hazard is: Moderate
Based on our recommended product application and the product's characteristics, the potential environmental exposure is: Low
If released into the environment, see CERCLA/SUPERFUND in Section 15.13. DISPOSAL CONSIDERATIONS
