Investigation of fragrance stability used in the formulation of cosmetic and hygienic products using headspace solid phase microextraction technique by nanostructural materials followed by gas chromatography-mass spectroscopy

چکیده مقاله

A new composite coating of polypyrrole and sodium lauryl ether sulfate was electrochemically prepared on a stainless-steel wire using cyclic voltammetry. The application and performance of the fiber was evaluated f or the headspace solid-phase microextraction of a fragrance in aqueous bleach samples followed by gas chromatography combined with mass spectrometry to assess the fragrance stability in this kind of household cleaning product. To obtain a stable and efficient composite coating, parameters related t o the coating process such as scan r ate and numbers of cycles were optimized using a central composite design. I n addition, the effects of various parameters on the extraction efficiency of the headspace solid-phase m icroextraction p rocess such as extraction t emperature and time, ionic strength, sample volume, and stirring rate were i nvestigated by experimental design methods using P lackett–Burman and Doehlert designs. T he optimum values of 53 C an d 28 min f or sample temperature and time, respectively, were f ound through response surface methodology. R esults show that the combination of polypyrrole and sodium lauryl ether sulfate i n a composite form presents desirable opportunities t o produce new m aterials to study f ragrance stability by headspace solid-phase m icroextraction.
