ULTRA BIOCID Ecological/Toxicological Studies
Metal corrosion Studies

These studies were performed by an outside certified laboratory.

Dermal Irritation/Corrosion Text
A modified Draise method was used as described in OECD guidelines for the testing of chemicals, Sec. 404, Paris1981(revised 1992). This study complies with the requirements of OECD Principles of GLP, Annex 2, Paris, 1981, revised as of July 1992. Ultra Biocid received a Primary Irritation Score of 2.1+- 0.9 and is classified as a "Mild Irritant". Ultra Biocid was also tested for skin irritancy in a formulated cleaner containing 20%. This test received a Primary Irritation Score of 1.2+-0.7 and is classified as a "Very Mild Irritant".

Metal Corrosion
NACE Standard - The corrosion rate is 0.6379 millimeters per year (mmpy). According to OSHA and DOT, a product is not corrosive if it does not exceed 6.25 mmpy at a test temperature of 55 degrees centigrade when tested in accordance with NACE Standard TM0169-76.

Mutagenicity
This product was found not to be mutagenic when tested by the Ames Assay, (OECD Guidelines for Testing of Chemicals, Sec. 471).

Biodegradation
The COD is 2300 mg/L. The test method used was Hach's Reactor Digestion Method for Waste Water and Sea Water. The Hach Reactor Digestion Method is a semi-micro adaptation of the Standard Methods. (For comparison, organic acids, surfactants, and glycol ethers will typically have CODs in the range of 1,000,000-2,000,000 mg/L.) The BOD is 6,100 mg/L. after 5 days and 7,100 mg/L. at 10 days. The test method used was Part 507 Oxygen Demand (Biochemical) of the Standard Methods for Examination of Water and Wastewater, 1985, 16th Ed.

LD-50 Test results: 1121 mg/kg (Rat, Oral)
