Comments on Physico-Chemical Properties Tests were performed according to EEC/OECD test guidelines at facilities complying with OECD Principles of Good Laboratory Practice. The notifiers state that the imidazolone rings may undergo hydrolysis under highly acidic conditions but the substance is expected to be stable in the environmental pH range. No information was provided on the adsorption/desorption properties of the chemical. Given the chemical's high water solubility and low partition coefficient it is anticipated that it will not strongly adsorb to soils. The notified chemical contains no dissociable hydrogens or basic functionalities. PURITY OF THE CHEMICAL Degree of Purity: 85% Toxic or Hazardous Impurities: Chemical name: formaldehyde CAS No.: 50-00-0 Weight percentage: ~ 0.05% Toxic properties: confirmed carcinogen with experimental carcinogenic, tumorigenic and teratogenic data; poison by ingestion; experimental poison by ingestion, skin contact, intravenous, intraperitoneal and subcutaneous routes; human systemic effects by inhalation: lacrimation, olfactory changes and pulmonary changes; human mutation data reported; human skin and eye irritant; frequent or prolonged exposure can cause hypersensitivity leading to contact dermatitis; an air concentration of 20 ppm is quickly irritating to eyes (1) Non-hazardous Impurities (> 1% by weight): unidentified impurities consisting of 5-15% of the notified chemical consist of dimers, trimers and oligomers Additives/Adjuvants: none
