Description

<p>Fragrances consist of several hundred different ingredients (hereinafter referred to as “fragrance components”) and impart the product function of fragrance to products such as liquid laundry detergents (hereinafter referred to as “detergents”). In fragrance quality control, it is necessary to comprehensively extract and analyze fragrance composed of multiple components to confirm that they are manufactured with the designed fragrance content and to quickly identify the cause of production problems. We have previously developed an analytical method for the quantification of fragrances in fabric softeners containing high concentrations of surfactants by combining the extraction method using a diatomaceous earth column with GC/MS measurement. However, when this method was applied to liquid detergents, which are representative products containing high concentrations of poly(ethylene oxide)-based nonionic surfactants, a decrease in fragrance recovery was observed due to insufficient control of emulsion formation. Therefore, we investigated sample loading methods, such as the applied volume of sample and the type of salt added, and developed a quantitative analysis method with good recovery rate and repeatability. This method enabled an accurate determination of the fragrance content of liquid detergents.</p>
