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

What is it about?

we reported the validation of a polarimetric method for the quantification of limonene-loaded nanoemulsions.

Why is it important?

Because Polarimetry is a rapid and reliable method to quantify chiral species in colloidal dispersed formulations, such as nanoemulsions.


Dr Vera Lucia Eifler-Lima

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.
