Limonene Microemulsions that Give Clear Dilutions

Add emulsifier and Butyl Cellosolve (if needed) to d-Limonene. Add water slowly, with agitation. The formulation will thicken then the viscosity will break to form a non-viscous product. 

This formulation can be adjusted to compensate for differences in grades of d-Limonene. 

More highly refined grades (fragrance grades) will give clear formulations with 5% Burco TME, 5% Burco FAE and 12% NP-9. 

1) Keep levels of Burco TME and Burco FAE equal. If the 5% levels do not give a clear concentrate, use 6% of each. 

3) Add Butyl Cellosolve as needed to yield clear concentrate.
