A wax-extender emulsion including a plurality of wax-extender complex particles suspended in water is described. A wax-extender complex includes a wax component, an organic extender component and a surfactant that stabilizes the wax component and the organic extender component collectively to form the wax-extender complex. The wax-extender emulsion comprises from 2 wt % to 30 wt % organic extender. During manufacturing, the organic extender and wax component are emulsified and homogenized together to produce the wax-extender emulsion. The wax-extender emulsion can be co-applied as a mixture with adhesive resin during wood-based composite manufacturing.
