Cetane Improver 2-Ethylhexyl Nitrate 2EHN 99% CAS 27247-96-7

Uses and Advantages
2-Ethylhexyl Nitrate has been used for decades to enhance the quality of petrodiesel and biodiesel fuels by raising the
cetane number. This additive may be used to improve ignition quality to give reduced noise, reduced emissions, better
cold startability, and improved fuel economy. Cetane Improver is recognized as a US EPA “Verified Retrofit
Technology” for NOx Reduction. In addition to reducing NOx, the use of Cetane Improver causes a reduction in other
diesel pollutants such as carbon monoxide hydrocarbons and particulate

Health Effects
Acute Health Effects
2EHN has undergone significant testing both internally as well as through the United States Environmental Protection
High Production Volume (HPV) program to determine the health and environmental effects. 2EHN has a low acute oral
and dermal toxicity when tested in animals. However, ingestion, dermal absorption, or inhalation of 2EHN can result in
enlargement of the blood vessels causing reduced blood pressure, known as vasodilation. Therefore, 2EHN is
classified as “Harmful if swallowed, in contact with the skin, or inhaled.” 2EHN is not considered a skin or eye irritant nor
is it considered a skin sensitizer. Based on the available data, 2EHN is not expected to cause reproductive,
developmental, mutagenic, or carcinogenic effects.

Environmental Effects
2EHN has been studied in vertebrate and invertebrate species, where some toxicity was seen. 2EHN is expected to
partition into the soil and has a low to moderate potential to bioaccumulate. The substance is classified as Toxic to
aquatic life with long lasting effects.

Exposure
The exposure guideline for 2EHN set by suppliers and manufacturers is 1ppm based on an 8-hour time weighted
average. In light of the potential temporary effects of overexposure, it is suggested that appropriate Personal Protective
Equipment (PPE) be used as reference standard for short-term exposure limits averaged over 15 minutes.
The appropriate PPE for 2EHN is:
• Level 1– Minimal Potential for Overexposure: requires the basic PPE to be used.
• Level 2– Moderate Potential for Overexposure: requires the use of chemical goggles, gloves and boots made
of nitrile or butyl rubber, coverall disposable Tyvek suit, a face shield and an organic vapor cartridge respirator.
• Level 3– High Potential for overexposure: requires a self-contained breathing apparatus, glove and boots
made of nitrile or butyl rubber, and an impervious suit made of nitrile or butyl rubber secured with tape at the
wrists.
