Plevan, HS&EA Manager Union Carbide Corporation Specialty Polymers & Composites Division Summary Epoxy Resin ERL-4221 was tested for potential autagenlc activity using the tlaonella/alcrosome bacterial mutagenicity assay (Aaes test). Epoxy Resin Hl-4221 was tested with and without aetabollc activation in triplicate at tve concentrations, ranging froa 0.1 to 10 milligrams per plate. The highest oncentratlon was cytotoxic In the mutagenicity tests and In a preliminary eat to choose appropriate doses. Positive dose-related Increases of the umbers of revertant colonies above the solvent control level were observed nly with metabolic activation with the two bacterial strains, TA100 and A1535, that detect base-pair substitution mutagens. Epoxy Resin ERL-4221 was a active mutagen in this In vitro screening test.

Bacterial Mutagenicity Attay 1. Introduction and Theory The Salmonella typhlmurlum/mlcrosome mutation attay it a microbial tcreenlng tett which detecta the ability of chemlcala to cauce genetic alterations In the hietldlne gene of selected indicator atrains of Salmonella typhlmurlum. The Indicator ttralnt used for this test are all histidinerequiring (his-) bacteria which carry a mutation In the histidine locus. The strains were obtained from Dr. Bruce Ames, University of California, Berkeley, CA. Histidine-independent (hls+) strains can arise either spontaneously or by the mutagenic action of a chemical or physical agent. Base pair mutagens cause a base change In the DNA molecule at the site of the original mutation or at a second site In the DNA which supresses the original mutation. Frameshift mutagens cause the addition or deletion of single or multiple base pairs In the DNA molecule. The relative frequency of Induced or spontaneous reversion to his+ can be quantltltated by plating the Indicator strains on minimal agar and counting the number of revertant colonies, representing bacteria that were able to grow and form colonies In the absence of histidine. To test the mutagenic potential of a test chemical, the bacterial strains are exposed to several concentrations of the chemical. Tests are done both with and without the addition of a mammalian liver homogenate (S9) because some chemicals require metabolic conversion for detection of their biological effects. Concurrent solvent and positive controls are also run with each assay to determine the responsiveness of the test system. After a suitable period of Incubation (48-72 hrs), direct revertant colony counts are made and evaluated. Test chemicals which produce at least a 2-fold and dose-related Increase In mutant colonies over the concurrent control value are considered to be bacterial mutagens and suspect mammalian mutagens.

Sample Preparation: The test substance was dissolved In dlmethylsulfoxlde (DMSO) to a concentration of 100 mg/ml for doses of 10 mg/plate and below. All subsequent dilutions were made In the same solvent. Dilutions of the test substance were made fresh each day of testing. All dilutions for the mutagenicity tests were gravlmetrlcally analyzed. 2. Dose Selection: A preliminary toxicity test was performed using strain TA100 to determine the level of toxicity of the test substance. Ten doses were tested for toxicity with a plate assay performed In the manner used for mutagenicity determinations. Toxicity was assessed at 24 to 48 hours after treatment by either growth Inhibition of the background lawn or a reduction In the number of spontaneous mutants. 3. Testing: The test chemical was tested In triplicate at five doses chosen to span a range which Included moderately toxic to relatively nontoxic concentrations. If the substance was nontoxic In the preliminary toxicity test, 100 pi of liquid or 50 mg of solid was used as the maximum dose, unless limited by solubility. Testing wsb performed both with and without metabolic activation. Concurrent solvent and positive controls were run In each test. Z. Quality Control Data from each test Is checked for accuracy and Integrity by a second Investigator not Involved with the study. Compliance of testing procedures with Good laboratory Practices la audited by the Independent Quality Assurance department at the Bushy Run Research Center. UCC 063002 Report 47-182 Page 5 HI. Results Epoxy Resin DtL-4221 was tested In a preliminary toxicity screen at 117.5, 30, 10, 3, 1, 0.3, 0.1, 0.03, 0.01, and 0.003 milligrams per plate with strain TA100 only. The top three doses of 117.5, 30, and 10 milligrams per plate completely inhibited growth of the background lawn. Based on these results, mutagenicity testing was done with 5 doses of 10, 3, 1, 0.3, and 0.1 sllllgrams per plate in triplicate. The highest dose was expected to produce sooe degree of cytotoxicity based on preliminary toxicity test results, observed as either a reduction In the number of revertant colonies or an Inhibition of growth of the background lawn. The range of doses that was tested followed the exposure concentration recommendations of the U.S. E.P.A. Health Effects Test guidelines (HC Gene Muta-S. typhlmurlun, August 1982). Gravimetric analysis of the Initial dilutions of the test substance for both tests Indicated no more than a 6.OX error from the stated concentration. All subsequent dilutions had no more than a 7.2Z error from the stated concentrations. All plate counts and the respective means and standard deviations are shown In Table 1 (without activation) and in Table 2 (with activation). No Indication of mutagenicity was observed at any of the tested doses without metabolic activation, either by evidence of a dose-response relationship or a doubling of the number of colonies over the solvent control value. With metabolic activation, dose-related mutagenic activity was observed with strains TA100 and TA1535 which detect base-pair substitution mutagens. The ratios of the average numbers of revertant colonies to the average number observed in solvent control cultures increased with Increasing dose as follows: 1.0, 1.1, 1.4, and 2.5-fold Increases with TA100; and 1.6, 2.0, 5.7, and 15.3 with TA1535. No evidence of mutagenic activity was observed with strains TA98, TA1537, or TA1538. All of the observed mutagenic effects of Epoxy Resin ERL-4221 appear to be base-pair substitutions following metabolic activation of the test agent* The mutagenic activity observed only with metabolic activation suggests the production of mutagenlcally active metabolites from the parent compound by the S9 activation system. Pose selection appeared to be In a suitable range In the mutagenicity tests because some toxicity was evident In both tests. In both tests, toxicity was observed at 10 mg/plate with all strains. All strains exhibited a positive mutagenic response with the positive controls tested both with and without S9 metabolic activation. Negative (solvent) controls were also tested with each strain, and the spontaneous reversion rates were within the historical ranges at this laboratory (see Appendix 3). All positive and negative controls were run concurrently with the test chemical. Concurrently run sterility checks showed that the S9 mix, RBS, the test chemical and all solvents and controls were sterile. UCC 063003 3328 Report 47-182 Pige 6 IV.

Introduction The strains used In this test are all Salmonella typhimurlum histidine auxotrophs developed by Dr. Bruce Ames of the University of California at Berkeley. The test Is designed to assay for reverse mutations In the histidine locus by plating the bacteria on minimal agar with only a trace of histidine. Bacteria that have undergone a reverse mutation In this locus can form colonies In minimal agar and are counted as mutants. The trace of histidine In the ainimal agar allows the bacteria to undergo a small number of cell divisions which then form the background lawn* visible as a cloudiness In the agar. Observation of the lawn permits an estimate of toxicity. Testing with growing cultures also allows potential mutagens to act on replicating DNA which Is often a more sensitive test for several classes of mutagens. B. Indicator Organisms Salmonella typhimurium strains TA98, TA100, TA1535, TA1537, and TA1538 are used In this assay. They all lack the excision repair mechanism, which Increases their sensitivity to potential mutagens. They also have a mutation effecting their llpopolysaccharide layer which allows large molecules to enter the bacteria more easily. Strains TA98 and TA100 were derived from strains TA1538 and TA1535 by the addition of an R factor which Imparts ampldllln resistance and also Increases sensitivity to several classes of mutagens. Indicator organisms are stored at -80*0. Working cultures are prepared sonthly by Inoculating nutrient broth from the frozen cultures and Incubating vlth agitation overnight. Bacteria are then plated onto Vogel-Bonner Medium E gar plates (master plates) with an excess of histidine and biotin (required because of the llpopolysaccharide deficiency). After Incubation for 24 hours, the strains are checked for their genetic markers to verify their Identity and purity (SOP #7.4.2A). For testing, the broth cultures are prepared by Inoculating from the setter plates Into nutrient broth and Incubated overnight with agitation. The broth cultures are then kept on Ice during the day of testing. Fresh cultures re made each day of testing. C. Toxicity Testing Sterile tubes are prepared containing 2 ml soft agar (6 g/1 agar and 5 g/1 NaQ) with a final concentration of 0.03 mM L-hlatldlne and 0.05 mM D-biotin (the entire mixture Is called top agar). Dilutions of the test chemical are ade In an appropriate solvent so that the correct amount of chemical can be added to each tube In 100 pi amounts. If less than 100 pi amounts of the test chemical Is used, phosphate-buffered saline Is used to adjust the total volume to 100 pi. UCC 063009 3334' Report *7-182 Appendix 1 Page 2 of 4 At least five doses are tested vltb maximum doses of 50 ag (for solids) or 100 id (for liquids) per plate for nontoxic chemicals, unless limited by solubility. Generally, a chemical cannot be considered to be nonautagenlc unless at least 5 ag/plate has been tested, unless limited by toxicity or solubility (deSerres and Shelby, 1979; HG-Gene Muta-S. typhlmurlum, August 1982). A 100 pi aliquot of an overnight broth culture of strain TA100 Is added followed by the appropriate amount of test chemical. The alxtur Is vortexed and poured onto the surface of a Vogel-Bonner Medium E agar plate (VB-E plate). The top agar la allowed to harden and the plates are Incubated at 37*C for 2* to 48 hours. The plates are examined for the condition of their background lawns and growth Is recorded as either confluent, sparse, or absent. Conflueacy Is considered an Indication of nontoxlclty, sparse growth Indicates moderate toxicity, and lack of growth la recorded as toxic. D. Dose Selection For the mutagenicity test, a minimum of five half-log doses are t sted within a range of moderately toxic to relatively nontoxic doses based on the results of the toxicity test. If all doses In the toxicity test were nontoxic, then a maximum dose of 50 mg or 100 pi Is used In the mutagenicity test, unless limited by solubility. E. Controls Concurrent solvent and positive controls are run with each test. The solvent control Is the maximum amount of solvent added with the diluted test chemical. For chemicals tested without dilution (l.e., by direct addition), water Is used as the solvent control. Both activation-dependent and activation-independent positive controls are used. The activation-independent controls are 4-nltro-o-phenylenediamlne for TA98 and TA1536, sodium azide for TA100 and TA1535, and 9-amlnoacrldlne for TA1537. The activation-dependent control In 2-amlnoanthracene (2-anthramlne) for all strains. The concentrations are determined from prior dose-response experiments on these chemicals and are Hated In the tables of results In this report. F. Metabolic Activation Each lot of Arodor-1254 Induced, rat-liver homogenate (S9) Is prescreened for activity with 7,12<dlmethylbenzanthracene to determine the appropriate amount to uae for testing. The S9 Is added to the "S9 mix" which contains, per ml, S9 (50-250 pi), MgCl2 (8 moles), KC1 (33 moles), glucose-6phosphate (5 moles), NADF (4 moles), and sodium phosphate, pH7.4 (100 moles). S9 mix Is prepared fresh each day of testing and kept at 0-4#C. G. Test Chemicals and Solvents The solvents of choice are water, DMS0 or ethanol. A minimum of five concentrations of the test chemical are diluted In the appropriate solvent and tested. The chemical Is diluted so that 100 yl will deliver the required UCC 063010 333S Report 47-182 Appendix 1 Page 3 of 4 dose. If smaller volume* are u*ed, phosphate-buffered saline Is added to adjust the total volume to 100 v>I* Test chemical solutions are prepared on the day of testing and are gravimetrically analyzed. If the analysis indicates > lOZ error from the Intended concentration, then either the dilution Is repeated or the actual concentration Is stated In the report. H. Dosing To a sterile tube containing 2 ml of top agar, 100 pi aliquot of the appropriate bacterial culture Is added followed by the addition of 100 pi of the appropriate solvent, control, or test chemical solution. Either 0.5 ml of 59 mix or 0.5 ml of phosphate-buffered saline (PBS) Is added for tests with and without metabolic activation, respectively. The top agar mixture is then poured onto a VB-E plate. Each dose Is tested In triplicate and with all five bacterial strains. Sterility checks are done on the PBS and/or S9 mix, all solvents, and the highest concentration of each test chemical. The plates are transferred to a darkened 37*C Incubator after hardening and incubated for 48-72 hours. I. Data Collection An Artek Model #880 Colony Counter Is used to count bacterial colonies or handcounts of the plates are done. The counter Is calibrated for each test to check the counting accuracy (SOP I7.4.5A). The numbers of colonies per plate are counted and recorded. An examination la also made of the background lawn on each plate. If toxicity Is observed as an Inhibition of growth of the background lawn, the plat* Is not counted, but Is recorded as toxic. If the background lawn Is sparse and the colony count Is still recorded, that number Is not used In the calculation of the mean number of colonies and Its standard deviation. J. Criteria for Test Validity and for Interpretation of Results The spontaneous reversion for the solvent controls should be within this laboratory's historical range. The positive controls should demonstrate that the test systems are responsive with known mutagens. A test chemical Is considered to be a bacterial mutagen If the number of revertant colonies Is at least twice the solvent control for at least one dose level and there Is evidence of a dose-related increase In the number of revertant colonies. If a test chemical produce* a marginal or weak response that cannot be reproduced In a second test, the test result will be considered negative. If there Is no evidence of a dose-related Increase In the number of revertant colonies and the number of revertant colonies is not twice the solvent control, then the test chemical Is not considered to be a bacterial mutagen.

Hengler Bushy Run Technical Center RD4, Mellon Road Export, Pennsylvania 15632 Dear Mr. Hengler: Infrared spectra have been run on the samples of cycloaliphatic epoxides that you returned to me recently. The spectra are enclosed for your files. The spectra that were obtained on these samples were compared with standard spectra for these products. In two cases, 4205 and 4299, comparisons were made with other samples of the these products that are being utilized in current laboratory programs. Comparison of these various spectra by the infrared experts in our Analytical Group (Dr. Clark and Mr. Lewis) led to the conclusion that the samples that you have are authentic samples of the UCC cycloaliphatic epoxides. Thus, the mutagenicity testing will be performed on valid samples of 4221, 4299, 4234, 4206 and 4205. ends. Very truly yours. RJCsmjk cc:Dr. . M. Clark, Mr. J. Lewis, Dr. R. E.
