Not available.

12. Ecological Information

Ecotoxicity

No further relevant information available.

Persistence and degradability

No further relevant information available.

Bioaccumulative potential

No further relevant information available.

Other adverse effects

• Water hazard class 1: slightly hazardous for water.
• Do not allow undiluted product or large quantities of it to reach ground water, water course or sewage system.
• Must not reach sewage water or drainage ditch undiluted or unneutralised.
• Rinse off of bigger amounts into drains or the aquatic environment may lead to increased pH-values. A high pH-value harms aquatic organisms. In the dilution of the use-level the pH-value is considerably reduced, so that after the use of the product the aqueous waste, emptied into drains, is only low water-dangerous.
