Polarimetry as an Analytical Method to Quantify Limonene-Loaded Nanoemulsions.

“

The use of polarimetry to measure the limonene in nanoemulsion represents an alternative analytical method, once the study demonstrated to be specific, linear, precise and accurate in the concentration range of 0.7 to 10 mg mL-1. Therefore, the method described here can be used in laboratories, once polarimetry is a low cost technique, easy to handle, reliable and fast, considering that evaporation steps are not required. Furthermore it allows the reduction of the volume of dangerous residues promoting benefits to the public health and to the environment.
