Enviroclean FA is biodegradable and is considered
non hazardous under DOT regulations. With a flash point greater
than 200°F (93°C), Enviroclean FA is safer to use than conventional
firearm cleaning solvents such as kerosene, acetone, xylene, toluene
and isopropyl alcohol.

Biodegradability - Eviroclean FA
A sample of Gun Solvent identified as Ogre Enviroclean FA was received
for determination of whether it met the requirement for biodegradability
according to ISO 10707.
The criterion for passing or failing the test according to ISO 10707 is that the product must achieve 60% Biodegradation within 10 days of the time that it first reaches 10% Biodegradation. The 100% mark for Biodegradation is taken to be the COD (Chemical Oxidation Demand). The Biodegradation is measured as the BOD (Biochemical Oxygen Demand). It is desired,therefore that the time at which the BOD equals 10% of the COD be found and that the BOD will reach 60% of the COD within 10 days of that time.
COD's were run on the three dilutions of the material and the average
was taken as the base COD figure. Three BOD series' were set
up and run to evaluate the rate of degradation. These were ready daily
for the first five days and then at two day intervals. There was a one
day "incubation" period
before any degradation was measurable, but it then proceeded
rapidly. The 10% degradation level was reached at an interpolated time
of 1 day, 10 hours. The 60% mark was reached at an interpolated time of
2 days 17 hours. The criterion of ISO 10707 is met therefore.
The OGRE Eviroclean is Biodegradable.

By the end of 18 days of degree of degradation (the ratio of BOD to COD) had reached 93.9%. The test was terminated.
In conclusion, Ogre Enviroclean is demonstrated to be biodegradable according to method ISO 10707.
