Advantage™ biodefoamers
Advantage biodefoamers comprise a family of patented products that effectively control foam in brown stock washers. The products are produced from natural agri-based oils (i.e., oil produced from agricultural produce) that are readily available and typically more cost effective than petroleum-based oils and synthetic silicone fluids. The products are biodegradable, FDA approved and available as an emulsion or a concentrate.
In addition to mitigating the impact of future raw material cost increases, Advantage biodefoamers have proven to be an effective replacement for silicone-based emulsion/concentrate products and conventional petroleum-based products. Commercial trials and ongoing applications demonstrate that the products provide improved defoaming, drainage and washer efficiency at a cost equal to or better than most mills’ existing defoamer programs.

Mode of Action
Similar to conventional brown stock defoamers, Advantage biodefoamers work by preferential surfactant displacement and physical bubble disruption. However, the agri-based oils used in the manufacture of the biodefoamers reduce the affinity of the liquor for pulp fibers, which in turn reduces liquor surface tension. The reduced surface tension allows for improved washer drainage.
