Studies have shown that normal alpha olefins have little or no toxic effect on animals except in very severe inhalation conditions. Based on the high oral and dermal LD50 values, these materials are considered to be relatively nontoxic. They produce minimal skin and eye irritation, and are not skin sensitizers. Laboratory exposures to very high airborne concentrations of C6-C16 normal alpha olefin vapors or mists produced central nervous system effects including anesthesia. Although not all products have been tested in genetic toxicity assays, the available data indicate normal alpha olefins are not mutagenic.

Ecotoxicity studies conducted with a wide range of products have shown little potential for toxicity to aquatic organisms under expected conditions of use or in the event of an accidental release. Not all alpha olefins are readily biodegradable, however they will ultimately biodegrade.  While the octanol/water partition coefficients of alpha olefins suggest a potential for bioaccumulation of these materials in aquatic organisms, the volatility of these materials (especially for the liquid alpha olefins) and the low-water solubility (indicative of limited bioavailability), would indicate that bioaccumulation will not occur.  Under most environmental scenarios, extensive evaporation and subsequent degradation in the atmosphere would preclude bioaccumulation.  Therefore, alpha olefins are not expected to be toxic to aquatic organisms, will biodegrade, and will not bioaccumulate.

Handling & Personal Protection

Chevron Phillips Chemical is committed to Product Stewardship and doing business responsibly. We endeavor to provide sufficient information for the safe use and handling of all our products. It is important to safeguard against excessive and prolonged exposures to normal alpha olefin vapors and mists. Unsafe vapor concentrations may not only be harmful to workers’ health, they may also constitute fire or explosion hazards.

No exposure limits have been established for these materials by the Occupational Safety and Health Administration (OSHA) or the American Conference of Governmental Industrial Hygienists (ACGIH).

Adequate local or general exhaust ventilation should be used to prevent the accumulation of high vapor concentrations. National Institute for Occupational Safety and Health (NIOSH)-certified organic vapor respirators or supplied air breathing apparatus should be used in the absence of reliable detection and warning devices.

Good industrial hygiene practices should always be followed. Avoid contact of normal alpha olefins with eyes and skin. Splashes in the eye should be treated by thoroughly flushing with water. Contaminated skin areas should be carefully washed with soap and water, and contaminated clothing should be laundered before reuse.
