DADMAC and PolyDADMAC

DADMAC and PolyDADMAC Uses

PolyDADMAC is a polymer manufactured from DADMAC. PolyDADMAC is often used to help remove suspended particulates from water.

DADMAC has no direct uses, but may be present when polyDADMAC is used.

PolyDADMAC is used in:
• Wastewater treatment
• Paper making
• Textile printing
• Silica sand mining

DADMAC and PolyDADMAC in the Environment

DADMAC and polyDADMAC may enter the environment through use in wastewater treatment plants. DADMAC and polyDADMAC are not being monitored for in Minnesota waters at this time.

Once in the environment, DADMAC is predicted to stay in water and soil for less than 60 days.

There is not enough information available on polyDADMAC to predict how long it may stay in the environment.

DADMAC is not expected to be toxic to fish or other wildlife. DADMAC is not expected to build up in the tissue of fish or other wildlife.

Exposure to DADMAC and PolyDADMAC

Exposure to DADMAC and polyDADMAC may occur through drinking contaminated water. It is possible to be exposed to DADMAC and polyDADMAC in occupational settings, including wastewater treatment plants and silica sand mines.

Potential Health Effects

While body weight changes have been seen in laboratory animals exposed to DADMAC and polyDADMAC, there is not enough information at this time to fully evaluate potential health effects of DADMAC or polyDADMAC.

Due to limited information on the toxicity of DADMAC and polyDADMAC, a full chemical review of these chemicals may not be possible.
