Justifications and discussions
- Category definition:
- HOPA olefins are acyclic hydrocarbon molecules having six to more than 30 carbons with a double bond between two of the carbons. Alpha olefins are molecules with a double bond at the end of the chain, the alpha position, while internal olefins have the double bond within the chain.
- Category description:
- Increasing Carbon Chain Length
- Category rationale:
- The category members are all members of the same hydrocarbon class, that is, they are all predominantly high carbon number olefins. The difference between category members is the length of the hydrocarbon chain or the carbon number range and the position of the olefinic bond. With respect to environmental effects, these hydrocarbon streams will all act via non-polar narcosis. The low water solubility of the higher carbon number members is expected to limit the aquatic toxicity. The mammalian toxicity data available on the category members suggests that the linear alpha olefins are relatively non-hazardous, with dermal irritation upon prolonged and repeated contact and pulmonary aspiration reflecting the principle concerns.
