442-487 Molecular Weight: the notified chemical was identified by infrared Method of (IR) spectroscopy Detection and Determination: major characteristic IR peaks identified at the following wavelengths: 2 924, 2 854, 1 732, Spectral Data: 1 610, 1 464, 1 350, 1 249, 1 118, 1 042, 949 and 856 cm -1 Comments on Chemical Identity Data from infra-red spectroscopy have been provided for the chemical. The structural formula for the notified chemical indicates that the alkyl chain length ranges from 10-16 carbon atoms. However, the CAS number given corresponds only to the 12 carbon homologue. It is noted that the poly(oxy-1,2-ethanediyl), - (carboxymethyl)-(dodecyloxy)-, compound with chitosan (a complex carbohydrate that is derived from D-glucosamine) is listed on the Australian Inventory of Chemical Substances (AICS). The inventory also contains the sodium salts of some higher homologues: poly(oxy-1,2-ethanediyl), -(carboxymethyl)-(tridecyloxy)-, sodium salt [(C2H4O)nC15H30O3.Na]; poly(oxy-1,2-ethanediyl), -(carboxymethyl)- (tetradecyloxy)-, sodium salt [(C2H4O)nC16H32O3.Na]; and poly(oxy-1,2-ethanediyl), - (carboxymethyl)--(hexadecyloxy)-, sodium salt [(C2H4O)nC18H36O3.Na]. 3. PHYSICAL AND CHEMICAL PROPERTIES The following physical and chemical properties unless specified otherwise are for the product containing the notified chemical at approximately 0.54% Hydrolysis as a Function Appearance at of pH: 20°C and 101.3 kPa: Adsorption/Desorption: Boiling Point: yellow liquid Density: Vapour Pressure: 100°C (water) Water Solubility: 1000 kg.m-3 (water) 2.39 kPa at 20°C Partition > 5 000 mg.L-1 (see comments below) not determined (see comments below)
