Ecological information (reference: 4, 5) |
| The
product should not get into any kind of water without treatment. Dissolved
in water, the material is easily biodegradeable (90 per cent) and
will not cause any disturbance in waste water treatment plants. Due
to its insolubility in water, larger amounts need to be eliminated
by separators, such as those typically used for fats and oils. Ecotoxicity:
none reported. |
| 13.
Waste disposal (reference: 4, 5) |
| Leak-and-spill
procedures |
: |
Sweep
up and store in closed containers. |
| Disposal |
: |
Stored
waste / recovered material used for recycling along with crude oils. |
| 14.
Transport recommendations (reference: 4, 5) |
| No
special conditions since it is not a regulated product. However, one
should observe the usual precautionary measures for transporting chemicals. |
| 15.
Regulatory requirements (reference: 4, 5) |
| According
to the data available, the product is not regulated. However, one
should observe prescribed federal, state and local measures for
dealing with chemicals. Listed on EINECS (EU), TSCA (USA), DSL (Canada
), AICS (Australia ), MITI (Japan), Korea and the Phillipines.
