Crosolv 30 are readily biodegradable, safe, VOC exempt green solvents targeted for household and I&I aqueous cleaning formulations. Crosolv 30 performs exceptionally well against greasy soils and is effective at low use rates of 0.3-3% when combined with non-ionic surfactants. Crosolv 30 can also be used neat or as a dilutable concentrate with higher surfactant levels.

Technical Details & Test Data+
Crosolv 30 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.
Minimum ratio of surfactant/solvent to solubilise green solvent in water
|Green solvent In formulation||NatSurf 265||Brij L7|
|Crosolv 30||3.5 : 1||4.5 : 1|
The NatSurf 265/Crosolv blend represents a powerful degreasing combination!
Additional testing was completed to compare the enhanced cleaning on pure crude oil. In this test Weatherford crude was spread on steel panels that were then submerged in a solution of NatSurf 265 + Crosolv 30 blend and NatSurf 265 alone. As shown in Figure 5, the panel submerged in the solution of NatSurf 265 + Crosolv 30 blend showed significantly faster cleaning. Crosolv 30 enables fast, safe cleaning with aqueous based systems
