Exposure Guidelines
A: General Product Information
Due to acute aquatic toxicity, prevent spillage and disposal of product into natural waters. Spilled product in
contact with water or moisture causes surfaces to become extremely slippery.
When dust is formed ensure sufficient workplace ventilation.
B: Component Exposure Limits
No information is available.
Engineering Controls
Provide adequate ventilation to minimize worker exposure.
PERSONAL PROTECTIVE EQUIPMENT
Personal Protective Equipment: Eyes/Face
Safety glasses
Personal Protective Equipment: Skin
Skin contact should be minimized. Impervious gloves (rubber or neoprene) are recommended.
Personal Protective Equipment: Respiratory
Use a nuisance dust mask for dusty conditions.
Personal Protective Equipment: General
CAUTION: Extreme slipping hazard when wet.
Obey reasonable safety precautions and practice and practice good housekeeping.

Biodegradability: Method: OECD 111 (EU C 7)
Abiotic degradation: Hydrolysis >70% (28 d), equivalent to ready
Biodegradability according to 67/54/EEC Annex VI.
Physico-chemical Because of its specific substantivity the product can be eliminated well in
removability biological waste effluent treatment plants.
Toxicity to daphniae:
Daphnia magna
EC50~35 mg/L
Exposure time 48 hours
Method: OECD Nr. 202
Further information: Acute earthworm toxicity.
LC50>1000 mg/l
Further information: Effects on aquatic organisms are due to an external (non-systemic) mode of action.
In addition the effects on aquatic organisms are attributable to the cationic charge of
the polymer. In natural surface waters this is neutralized by irreversible adsorption
to particles and dissolved organic carbon. This reduces the toxicity in surface waters
by more than 10-fold.
Further information: Data reported in sections 11 and 12: have been determined on a comparable product in the
Laboratory for Toxicology and Ecology, Stockhausen GmbH & Co. KG, Krefeld, Germany
B: Component Analysis - Ecotoxicity - Aquatic Toxicity
Citric acid (77-92-9)
96 Hr LC50 Lepomis macrochirus: 1516 mg/L [static]; 96 Hr LC50 Leuciscus idus: 440 mg/L [static]
Environmental Fate
Biodegradation is negligible, possibly due to the highly polymerized structure of the polyacrylamides. However,
the substance is removed from waste water effluent due to flocculation with the bio-sludge.
