NECS , ( Apparentl y no chloride data was submitted for the Primary Amine salt registrations in Europe .) The justification for this using data on the Oleylamine is that the substance will alway s bind a counter ion at environmental pH . E xisting data on the amine is being submitted to support the complementary

amine hydrochloride. The test substance for these studies is Armeen OD which is a purified preparation of the primary amine precursor of the new chemical 9

### Acute Toxicity to Fathead Minnow **Date:** 09/05/95 **Laboratory:** Akzo Nobel Central Research Arnhem **Results:** The test article was described as a ye llow liquid with ammonia

odor. Oleylamine was tested in the absence and presence of humic acid. Stock “dispersions” of test article were prepared in water using ultrasonic treatment. Only nominal concentrations of test article were reported. LC50 (96

-hour) Value Humic Acid Concentration LC50 = 0.11 mg/l 0 mg/l LC50 = 1.50 mg/l 10 mg/l LC50 = 2.13 mg/l 20 mg/l The test article was highly toxic to fathead minnow under the conditions of this test, in the absence of humic acid. The addition of humic acid (to simulate water sources in the actual environment) at a level of 10 mg/l resulted in a substantial (approximate 10 fold) reduction in toxicity. This study was submitted to the U.S. EPA under a TSCA Section 4 Test Rule/SIDS program. **Study Type :**  **Acute Toxicity to Daphnia magna Date:**  10/24/95 **Laboratory:** Akzo Nobel Central Research Arnhem **Results:** The test article was described as a yellow liquid with ammonia odor. Stock

The addition of humic acid (to simulate water sources in the actual environment) at a level of 10 mg/l resulted in an approximate 40 fold reduction in toxicity

absence and presence of humic acid. Stock “dispersions” of test arti cle were prepared in water using ultrasonic treatment. Onl y nominal concentrations of test article were reported. **EC50 Value Humic Acid Concentration**  EC50 (growth) = 0.03 mg/l 0 mg/l EC50 (growth rate) = 0.04 mg/l 0 mg/l EC50 (growth) = 0.23 mg/l 5 mg/l EC50 (growth rate) = 0.37 mg/l 5 mg/l EC50 (growth) = 0.49 mg/l 10 mg/l EC50 (growth rate) = 0.76 mg/l 10 mg/l The test article was highly toxic to green algae under the conditions of this test, with respect to both growth and growth rate. The addition of humic acid (to simulate water sources in the actual environment) resulted in an approximate 10 fold reduction in toxicity, however, even with this reduction in toxicity , the test article was still highly toxic to the test species.

**Study Type: Biodegradation**  **Date:** 02/28/92 **Laboratory:** Akzo Research Laboratories Arnhem **Results:** The test article was described as a liquid. The test article was biodegraded

44% at day

28, and 72% at day

42. Total mineralization was reported at day 42. Although the test article was not readil y biodegradable b y the OECD definition, it can be classified as inherentl y biodegradable. Because the test article was biodegraded (mineralized) up to 72%, the test article can also be described as ultimately

biodegradable. **Conclusions: Armeen OD was ultimately biodegradable in the Closed Bottle Test.**
