The LD50 for skin absorption In rabbits is>I0,000 m9ft. <br />Iggvstion, The oral LD50 for rats is 10,000.34.000 mg/kg. <br />w <br />Mutagenielty+ In vitro mutagenicity studios wore nebrntive, Animal nitiWenlolty studies were negative. <br />12. ECOLOGICAL INFORMATION <br />Movement & Partitiopiug: Based largely or completely on infbrtnation for similar material(s). i.e., propylene <br />glycol, Bioeonoentratlon potential is low (1301' less than 100 or LOS Pow less than 3), Log octanol / water partition <br />coefYiciont (log Pow) is —0.92, Henry Law Constant (Fl) Is 1.2E-8 atnt.m3/nYole. <br />Degradsitlou & Transformation: Based largely or completely on Information for similar material(g) it,, <br />propylene glycol, Biodegradation under aeroble static laboratory conditions is hich (BO1)20 OR SOD28IT101a <br />greater than 400A). t9lodegradation is expected to be achievable In a secondary wastewater treatment plant. 5-d0.y <br />biochemical wtygea dmmand (801 5) is 1,16 p/p. 200 -day bioohomical oxygen demand (BOD20) Is 1,43 p/p. <br />theomtleal oxygon demand (TKOD) is calculated to be 1.68 p/p. Inhibitory concentration (IC50) In OECD <br />Activated Sludge Respiratlon inhibition Test (OECD Teit No. 209) Is greater than 1 gm/L. Degradation Is expected <br />In the atmospheric environment within minutes to hours. <br />Ccutoxicology: Basod largely or completely on information for similar material (s), I.e., propylene glycol, Material <br />is practically non-toxic to aquatic organisms on an acute basis (LC50 greater than 100 mg/L in most sensitive <br />species). <br />Acute LC50 far fathead minnow (Pimephales promelas) is 4,600-54900 mg/L <br />Aoute LC50 fbr guppy (Poacllia roticulatx) is greater than 10000 mg/L. <br />ACute LC50 for water flea Daphnia magna is 4850-34400 mg/L <br />Acute LC30 for rainbow trout (Oncorhynchus mykiss) Is 44mL/L (about 44000 mg/L) <br />13.
