Performance Highlights

Performance Interfacial Tension

The primary function offered by CRODAQUAT DGR is that of degreasing. To effectively degrease a surface with a water-based cleaner, one needs to provide a means to encourage oily soils to release from the surface and enter the wash liquor. A key criterion to making this happen is greatly reducing the interfacial tension between the soil and detergent solution. The chart below shows the clear superiority of CRODAQUAT DGR in reducing interfacial tension compared to 3 competitive degreaser oriented surfactant blends.

Performance – Surface Oil Removal

The following pictures demonstrate the speed and the efficiency at which CRODAQUAT DGR will remove oil from a surface. Painted steel panels are coated with used motor oil and submerged in 0.33% w/w solutions (50ºC) of CRODAQUAT DGR and its closest competitor. The images below show remarkable performance differences. In the CRODAQUAT DGR solution the oil almost immediately begins to effervesce from the surface. After a short while, the wash liquor has become very clouded with the liberated oil. By contrast, significant time transpires before any oil is actually liberated into the wash liquor containing the competitive product. When the test is terminated at 5 minutes, the panels were evaluated for cleaning efficiency using a reflectometer. CRODAQUAT DGR is shown to be 52% more effective in oil removal.

Performance – Grease Removal

Many find that a product that may work well on oily soils might not do as well on grease. CRODAQUAT DGR proves to be effective against both soil types. To demonstrate grease removal capabilities, CRODAQUAT DGR was compared with several competitive surfactant systems on vinyl tiles coated with a lithium grease/carbon black soil. Grease-coated tiles were submerged in a 0.33% w/w surfactant solution (25ºC) for four minutes. The tiles were then removed from the treatment bath and rinsed for 5 seconds under a gentle stream of cold tap water. One can see from the resulting images and chart that CRODAQUAT DGR is vastly superior to all competitive products when cleaning greasy soils.
