APPLICATION:

Newcomer Supply Formalex^® “GREEN” Formalin Neutralizer is a multi-component, aqueous formulation which utilizes an organo-nitrogen based chemistry.  This organo-nitrogen chemistry effectively neutralizes Formalin waste products by chemically reacting with the formaldehyde to yield non-hazardous, pH neutral, water soluble compounds that can be safely discharged to sewer and waste water treatment systems.

32 ounces of Formalex^® “GREEN” will neutralize one gallon of 10% formalin or one gallon of 4% glutaraldehyde.

Benefits include:

• No pH adjustment of solutions is required.
• Does not contain phosphates.
• Non-vapor forming.
• Formalin or glutaraldehyde can be neutralized in 4 hours to non-hazardous disposable solutions.
• Neutralized aldehyde products can be safely discharged to sewer and waste water treatment systems.
• No sludgy residue.

Formalex^® “GREEN” recommended accessories to assist and complete the neutralization process.

• 1 Gallon or 2.5 Gallon Waste Collection Container
• Funnel with Tissue Screen
• 32 Ounce Graduated Dispenser
• pH Test Strips

NEUTRALIZING PROCEDURE:

1. Collect acceptable concentrations of aldehyde waste in designated and well labeled Formalex^® Green Waste Collection Container, 1 Gallon or 2.5 Gallon (ABFXG-1, ABFXG-25).
   1. See Procedure Notes #1 and #2.
   2. Use of Funnel with Tissue Screen (ABFX-FUN) is recommended to avoid any extraneous tissue debris from accumulating in aldehyde waste solutions.
2. Add 32 fluid ounces of Formalex^® “GREEN” to each gallon (128 fluid ounces) of aldehyde waste. Or add 1 liter of Formalex^® “GREEN” to 4 liters of aldehyde waste.
   1. Use Formalex^® Green 32 Ounce Graduated Dispenser (ABFXG-GD) for convenient measuring.
   2. Refer to Page 2 for treatment calculation tables.
3. Securely tighten lid on collection container; agitate container to thoroughly mix solutions.
   1. Do not add any additional solutions to collection container once neutralization process has started.
4. Allow mixed solution to stand for a minimum of 4 hours.
   1. See Procedure Note #3.
5. Prior to re-opening, re-agitate container to thoroughly re-mix solution to decrease exposure to any potential headspace vapor.
6. Test treated solution with Formalex^® Green pH Test Strips (ABFXG-PH) to determine completion of neutralization reaction.
   1. Reaction is complete with a pH reading at or above 5.5.

7. Pour neutralized non-hazardous aldehyde waste product into sanitary sewer.
8. Rinse collection container and clean with cold tap water before reuse.
9. Use Formalex^® Green Spray Bottle (ABFX-32E) to neutralize small formalin spills and accompanying formalin odors.

PROCEDURE NOTES:

1. 10% formalin (4% formaldehyde) and 4% glutaraldehyde are the highest concentrations that can be neutralized.
   1. Formalex^® “GREEN” should never be used to directly treat concentrated 37% formaldehyde for sanitary sewer disposal.
2. Maintain separate, well labeled collection containers for waste formalin and waste glutaraldehyde solutions for best neutralization results.
3. To attain the lowest formalin residual, allow treated solutions to stand overnight or approximately 8-12 hours.
4. Confirm disposal methods with local and state environmental regulations. Refer to SDS for personal protective measures and handling information.

BEST USED BY INFORMATION:

Formalex Green is best when used within 24 months from production date.  The last four digits of the batch number represent the production date in a Julian calendar format (eg. 1239 = 123rd day of 2019).
