Matex Non alcohol-based high performance foam
FOAMER ES  is a non alcohol-based foam used for diamond and rotary drilling applications.
FOAMER ES provides and environmentally acceptable foaming agent to be used in mineral exploration, oil and gas exploration and water well drilling operations.
FOAMER ES  has an excellent half-life comparable to the leading foams on the market.
FOAMER ES  gives an immediate tight foam with good lifting characteristics.
FOAMER ES can be enhanced by the addition of Matex Hole Control or Ultravis to create significantly stiffer foam if required.
 
Below is a biodegradability chart comparing FOAMER ES to a common foaming agent.  The biodegradability of the FOAMER ES is 99.9% after 2 to 3 days. 
The second point to consider is that the other component besides the one in the SDS is water.
