Secondary notification assessment Polysiloxanes, di-Me, 3-[3-[(3-coco amidopropyl) dimethylammonio]-2-hydroxypropoxy] propyl group-terminated, acetates (salts) for public comment

The National Industrial Chemicals Notification and Assessment Scheme (NICNAS) has conducted a secondary notification assessment of Polysiloxanes, di-Me, 3-[3-[(3-coco amidopropyl) dimethylammonio]-2-hydroxypropoxy] propyl group-terminated, acetates (salts) (CAS No 134737-05-6). The assessment was conducted under the Commonwealth Industrial Chemicals (Notification and Assessment) Act 1989 (ICNA Act), as amended. The agency declared the polymer required secondary notification in the July 2016 Chemical Gazette.

Why the polymer needed a secondary notification

The polymer required reassessment because:

  • new data indicated that the short-chain form of CAS No 134737-05-6 (ABIL Quat 3270; number average molecular weight (NAMW) ~1670) is a skin sensitiser and has environmental toxicity, and
  • the introduction volumes may have changed significantly since the polymer was first assessed.

About the secondary notification report

The report evaluates the relevant new information and considers the impact on the potential:

  • human health, and
  • environmental risks that may be associated with exposure to the notified polymer.

Assessment findings – report recommendations

NICNAS is recommending to Safe Work Australia that the notified polymer be classified and labelled according to the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) as:

  • Skin sensitiser (Category 1A): H317—may cause an allergic skin reaction
  • Acute Aquatic Toxicity (Category 1): H400—very toxic to aquatic life
  • Chronic Aquatic Toxicity (Category 1): H410—very toxic to aquatic life with long lasting effects.

NICNAS is also recommending that the classification include a note that the classification only applies to polymer grades with NAMW < 10,000.

Request for variation applications

A request for variation to the report may be made (Download the Application for Variation (Form 4a))
