Molecular Weight Requirements Yes Functional Group Equivalent Weight (FGEW) Requirements Yes Low Charge Density Yes Approved Elements Only Yes Stable Under Conditions of Use Yes Not Water Absorbing Yes Not a Hazard Substance or Dangerous Good Yes The notified polymer meets the PLC criteria. PHYSICAL AND CHEMICAL PROPERTIES Appearance at 20 °C and 101.3 kPa Yellowish to brown powder with characteristic odour Not determined (showing a softening effect starting at approx. 40 oC) Density 300-600 kg/m3 Water Solubility Not determined. Expected to be water soluble based on the presence of hydrophilic functional groups in the chemical structure. Dissociation Constant Not determined. The notified polymer is a salt and is expected to be ionised under environmental conditions. Particle Size D(0.5) =127 m Reactivity Stable under normal environmental conditions Degradation Products None under normal conditions of use INTRODUCTION AND USE INFORMATION Maximum Introduction Volume of Notified Chemical (100%) Over Next 5 Years Year 1 2 3 4 5 Tonnes < 1 < 1 < 1 < 1 < 1 Use The notified polymer will be imported at a concentration < 0.2% as a component of grout (plasticiser) and mixed with water at the construction site to be used for the base of onshore wind turbines (wind farms) or grouting pile connections on offshore structures such as wharves and ship berthing facilities. HUMAN HEALTH RISK ASSESSMENT ENVIRONMENTAL RISK ASSESSMENT No ecotoxicological data were submitted. Anionic polymers are known to be moderately toxic to algae. The mode of toxic action is overchelation of nutrient elements needed by algae for growth. The highest toxicity is when the acid is on alternating carbons of the polymer backbone. This is not likely to apply to the notified polymer. However, the toxicity to algae is likely to be further reduced due to the presence of calcium ions, which will bind to the functional groups. The notified polymer will not be manufactured, reformulated or repackaged in Australia. Therefore, release of the notified polymer from these activities is not expected. Spills of the notified polymer from grout mixing are expected to be minimal. Spills are expected to be collected and disposed of with to a licensed waste facility. The empty containers are expected to be recycled.
