Crosolv 50 is a low VOC environmentally friendly solvents. It is readily biodegradable, safe, VOC exempt solvent targeted for household and I&I aqueous cleaning formulations. Crosolv performs exceptionally well against greasy soils and is effective at low use rates of 0.3-3% when combined with non-ionic surfactants. Crosolv can also be used neat or as a dilutable concentrate with higher surfactant levels.

Water Solubility and Formulating

Crosolv 50 have low solubility in pure water, <0.1% by weight, however, they are easily solubilised in surfactant solutions, especially using non-ionic cleaning surfactants such as NatSurf™ 265 or Brij™ L7.

The NatSurf 265/Crosolv blend represents a powerful degreasing combination!

Performance Data – Crude Oil Soil

Additional crude oil soil testing was conducted with Crosolv 50 where it was post-added to three commercial cleaners (and the Green Cleaner) at 1%. All formulations were clear and stable. As shown in Figure 4, the addition of Crosolv 50 to all the commercial cleaners led to a significant enhancement of cleaning performance of oily soil compared to cleaner alone.

Performance Data – Competitive Products

A Sheen Scrub Test was conducted to compare the cleaning performance of Crosolv 50 and a competitor green solvent when added to the Green Cleaner formulation at 1%. Performance was also compared to propylene glycol n-butyl ether at 1% (a benchmark solvent widely used in aqueous cleaning formulations) and the Green Cleaner alone. Results are shown in Figure 8.

Figure 8: A Green Cleaner with 1% Crosolv 50 demonstrated a slightly better cleaning result over a competitor green solvent replacement and significantly better cleaning than glycol ether or the Green Cleaner control.
