AICIS listing: Searched for but not found

DISCLAIMER: Downloaded AIIC Inventory records searched were supplied by AICIS, dated 1 September 2022, and updated as since published by AICIS according to the Act.

AICIS's disclaimer includes the words ... '[Downloaded records] should not be relied on for the latest information about a chemical – you must search the online Inventory to see if your chemical is listed and what any terms of its listing are.'

Records to prove one of the following:

• the number average molecular weight (NAMW) of the polymer is ≥ 10,000 g/mol and the polymer has:

- < 2% (by mass) of molecules with molecular weight < 500 g/mol; AND

- < 5% (by mass) of molecules with molecular weight < 1,000 g/mol.

AICIS will accept a GPC analysis report.

• the NAMW of the polymer is ≥ 1,000 g/mol and < 10,000 g/mol and the polymer has:

- < 10% (by mass) of molecules with molecular weight < 500 g/mol; AND

- < 25% (by mass) of molecules with molecular weight < 1,000 g/mol; AND

- a functional group equivalent weight (FGEW) of ≥ 5,000 g/mol if the polymer includes high-concern reactive functional groups, or an FGEW of ≥ 1,000 g/mol if the polymer includes moderate-concern reactive functional groups.

AICIS will accept a GPC analysis report and associated calculations.

• the polymer is a polyester manufactured solely from prescribed reactants.

AICIS will accept chemical identity information on the polymer constituents

Records to prove the polymer has a low cationic density. You’ll need to prove one of the following:

• the polymer is not a cationic polymer or is not likely to become a cationic polymer in a natural aquatic environment (4 < pH < 9), if applicable. AICIS will accept chemical identity information on the polymer constituents and a representative structural formula of the polymer.

• the combined (total) FGEW of cationic groups is at least 5000 g/mol. AICIS will accept a GPC analysis report and associated calculations.

• the polymer is not soluble (< 0.0001 g/L) or dispersible in water and will only be used in solid phase (for example, ion exchange beads). AICIS will accept a study report and information on how the polymer will be used

OECD Test 105: Water Solubility

(OPPTS 830.7840)

OECD Test 120: Solution/Extraction Behaviour of Polymers in Water

Information that demonstrates that the polymer is protected from degradation by being encapsulated during use, or

information that demonstrates that all of the following applies to the polymer:

- it is not designed to be pyrolysed or burnt, and

- it is not designed or reasonably anticipated to substantially photodegrade, and

- it is not designed or reasonably anticipated to substantially biodegrade, and

- it is not explosive, and

- it is hydrolytically stable (T½ greater than or equal to 12 hours), and

- it is not a biological polymer, and

- it is not a polysaccharide, and

if it is a polymer that contains polyethylene glycol (PEG) functionalities and has a solubility in water of greater than 200 mg/L - measured data demonstrates that the polymer does not substantially biodegrade, and

if it is a polymer that contains polypropylene glycol (PPG) functionalities and has a solubility in water of greater than 200 mg/L - measured data demonstrates that the polymer does not substantially biodegrade

OECD Test 120: Solution/Extraction Behaviour of Polymers in Water

Records to prove that the polymer:

• contains approved elements only; AND

• does not contain any difluoromethylene or trifluoromethyl groups.

AICIS will accept chemical identity information on the polymer constituents and a representative structural formula of the polymer

Records to prove the chemical meets the AICIS definition of a polymer. AICIS will accept a GPC analysis report and information on the polymer constituents (including the weight percentage prior to polymerisation and any residual)
