SECTION 12: Ecological information
The information below may not be consistent with the material classification in Section 2 if specific ingredient classifications 
are mandated by a competent authority. Additional information leading to material classification in Section 2 is available 
upon request. In addition, environmental fate and effects data on ingredients may not be reflected in this section because an 
ingredient is present below the threshold for labelling, an ingredient is not expected to be available for exposure, or the data 
is considered not relevant to the material as a whole.
