Six rabbits were administered a dermal dose of 0.5 to one intact and one abraded skin site and observed for 3 days in vitro assessment using Salmonella typhimurium with and without S-9 activation at 16 dose levels between 2,000 and 0.78125 µg/plate. five male and five female rats were held in a tapered, polycarbonate restraining tube fitting onto a single tier of the exposure chamber and sealed by means of a rubber 'O' ring. Only the nose of each animal was exposed to the test atmosphere. The dose for each individual test bird was gravimetrically measured and dispensed at the appropriate dosage rate into gelatin capsules. The test material was administered by oral insertion of the gelatin capsule into the esophagus, followed by a hand massage down the esophagus towards the proventriculus. Groups of twenty-five mated female Sprague- Dawley CD strain rats were dosed orally, by gavage, with the test material from Day 6 to 15 of gestation inclusive. The dose levels were 100, 300 and 1000 mg/kg/day. A concurrent control group was dosed with vehicle only. All reasonable measures are taken to ignite the dispersed dust sample in air under ambient temperature and pressure conditions. No deaths. Clinical signs of reaction to treatment were piloerecion with complete recovery by day 3. Oral LD 50 > 5.0 g/kg body weight Transient very slight irritation of observed at the abraded sites of three animals. Primary Irritation Index was calculated to be 0.1. No evidence of mutagenic activity was seen at any dose level. The LC50 of the test material has been determined to be greater than 5.18 mg/l (1/5 mortalities in the male group, 0/5 mortalities in the female group). The acute oral LD50 of Experimental Additive 9823-37 was determined to be greater than 2000 mg/kg body weight. With regard to sublethal effects (diarrhea was noted 7.5 hours post-dosing and on Test Day 3 of the study in the 2000 mg/kg group), a NOEL was not achieved in this study. With regard to mortality, the NOEL was 2000 mg/kg body weight. Females dosed with Experimental Additive number 9823-37 from Day 6 to 15 of gestation at dose levels up to and including 1000 mg/kg showed no evidence of maternal toxicity and no significant effects on the growth and development of offspring. Sample tested was classified as NOT EXPLOSIBLE.

Assessments were made at approximately 1 hour and 24, 48 and 72 hours following treatment. A group of ten animals ( five males and five females) were given a single 24- hour, semi - occluded dermal application to intact skin at a dose level of 2000 mg/kg bodyweight. The animals were observed for fourteen days after the day of treatment. Magnusson & Kligman maximization study in the Guinea pig. 10 test and 5 control animals. Thestudy was performed in compliance with OECD guideline 406, and OPPTS 870.2600. Groups of 10 male and 10 female rats were administered to the test substance in the diet for 13 weeks at a concentration of up to 20000 ppm. This test was performed to meet the requirements of OECD 408 and OPPTS 870.3100. L5178Y TK +/ - 3.7.2c mouse lymphoma cells were treated with the test substance at up to six dose levels, in duplicate, together with solvent and positive controls. 3-Hour exposures were used both with and without activation in experiment 1. In experiment 2 the exposure time without activation was increased to 24 hours. A third experiment was performed using a 3-hour exposure without metabolic activation to confirm a result obtained in experiment 1. This test was performed to meet the requirements of OECD 476 and OPPTS 870.5200. The test material, Experimental Additive 9823-37, produced a maximum group mean score of 12.0 and was classified as a Mild Irritant (Class 4 on a 1 to 8 Scale) to the rabbit eye according to a modified Kay and Calandra classification system. The acute dermal median lethal dose (LD 50 ) of the test material, Experimental Additive 9823-37, in the Sprague-Dawley CD Strain rat was found to be greater than 2000 mg/kg bodyweight. The test material, Experimental Additive 9823-37, produced a 0% (0/10) sensitisation rate and was classified as a non-sensitiser to guinea pig skin. Preliminary results available. No draft report as of yet Experimental Additive 9823-37 induced small but reproducible statistically significant increases in the mutant frequency at the TK +/- locus in L5178Y cells in the absence of metabolic activation. Experimental Additive 9823-37 was therefore considered to be mutagenic under the conditions of the test.

The study was conducted using the intraperitoneal route in groups of seven mice (males) at the maximum recommended dose (2000 mg/kg) with 1000 and 500 mg/kg as the two lower dose levels. This test was performed to meet the requirements of OECD 474 and OPPTS 870.5395. Objective of this study is to investigate the effects of the test material on reproduction, prenatal development and post-natal development of the rat when administered to two successive generations. This report was conducted in accordance with the Environmental Protection Agency (EPA) Good Laboratory Practice Standards, 40 CFR 160. Experimental Additive 9823-37 was considered to be non-genotoxic under the conditions of the test. Study is in-process. Expest draft report April 2002. A solubility study was performed on Experimental Additive 9823-37, an antimicrobial agent zirconium phosphate-silver complex. The concentration of zirconium and silver were determined for solvents saturated with the test substance at 25ºC. The concentrations of zirconium and silver were determined in the following solvents: Water buffered to ph 5 Water buffered to ph 7 Water buffered to ph 9 Pure Water (Processed through a Milli-Q purification system) The solvents were equilibrated with an excess of the test substance at 30ºC for 24, 48 and 72 hours. After equilibration the samples were reequilibrated at 25ºC for 24 hours. The samples were then filtered and an aliquot of each sample was sent to Galbraith Laboratories for analysis by Inductively Coupled Plasma Atomic Emmision Spectroscopy (ICP- AES). The results are summerized below.
