Dissociation data for the notified chemical, which is a substituted phenol, were not supplied. Substituted phenols are weakly acidic (Morrison & Boyd 1976). Despite the notifier claiming that the chemical will not dissociate, it is possible that some dissociation will occur in the environmental pH range of 4 to 9. 4. PURITY OF THE CHEMICAL Degree of Purity: Not applicable, the chemical is a UVCB Hazardous Impurities: Calcium hydroxide Chemical name: 1305-62-0 CAS No.: 0.5% Weight percentage: Irritant Toxic properties: Phenol, (tetrapropenyl) derivatives manufacture of Chemical name: distillation residues 220794-73-0 CAS No.: 0.1% Weight percentage: Skin irritant Toxic properties: Phenol, (tetrapropenyl) derivatives Chemical name: 74499-35-7 CAS No.: 1% Weight percentage: Skin irritant Toxic properties: Phenol, C20-30 alkyl derivatives Chemical name: - CAS No.: 1.5% Weight percentage: Skin irritant Toxic properties: Non-hazardous Impurities Details claimed as exempt information. (> 1% by weight): Additives/Adjuvants: 20% diluent oil, hydrotreated or solvent refined, heavy paraffinic distillates. Exact details of solvent are claimed as exempt.
