Section 12 - Ecological Information

Ecotoxicity: No data available. Estimated Koc value = 109.1. This value suggests that episolon-Caprolactone will show high mobility in soil. Estimated BCF value = 4.94. This values indicates that bioconcentration of this product in aquatic organisms and sediment should not be important. Epsilon-Caprolactone exists in the vapor phase in the ambient atmosphere and will be degraded slowly by the reaction with photochemically produced hydroxyl radicals.
Environmental: No information available.
Physical: No information available.
Other: Do not empty into drains.

Section 13 - Disposal Considerations

Chemical waste generators must determine whether a discarded chemical is classified as a hazardous waste. US EPA guidelines for the classification determination are listed in 40 CFR Parts 261.3. Additionally, waste generators must consult state and local hazardous waste regulations to ensure complete and accurate classification.
