Technical Basis
A review of available sources identified the following for a similar chemical, di-n-amylamine (CASRN: 2050-92-2): LCLo and LD50 (rat, rabbit) toxicity data for various routes (oral, skin, and inhalation). Data sources were selected according to the hierarchy listed in Table 3.1. Toxicity data were selected according to type of exposure, species, and route according to the hierarchies stated in Sections 3.3.1, 3.3.2 and evaluated using factors in Tables 3.2, 3.3, and 3.4. Inhalation exposures were scaled to 60-minute equivalents using the ten Berge equation (Section 3.3.4). The most preferred species and data type, a rat LCLo, was selected as the TEEL-3 basis. TEEL-2 and TEEL-1 values were derived according to Table 3.5.
• TEEL-1 = TEEL-2/11
• TEEL-2 = TEEL-3/6
• TEEL-3 = Rat LCLo (di-n-amylamine, CASRN: 2050-92-2, 63 ppm/4H)
This review generated TEEL values that are consistent with Rev. 29A.
