Determination of fragrance content in perfume by Raman spectroscopy and multivariate calibration

• Determination of fragrance content in perfumes.
• Methodology is based on Raman spectroscopy associated with multivariate calibration.
• Results were consistent with the conventional method based on GC-MS.
• Use of ethanol bands in the modeling is important, but not decisive, for quantification.
• The methodology promotes a rapid determination, with easy operation, low cost and nondestructive conditions.

An alternative methodology is herein proposed for determination of fragrance content in perfumes and their classification according to the guidelines established by fine perfume manufacturers. The methodology is based on Raman spectroscopy associated with multivariate calibration, allowing the determination of fragrance content in a fast, nondestructive, and sustainable manner. The results were considered consistent with the conventional method, whose standard error of prediction values was lower than the 1.0%. This result indicates that the proposed technology is a feasible analytical tool for determination of the fragrance content in a hydro-alcoholic solution for use in manufacturing, quality control and regulatory agencies.
