“…Common calibration methods, such as external standard and standard addition, do not completely remove the matrix effect. Multiple headspace-SPME (MHS-SPME) 29 is a recent method developed to quantify solid samples, since it removes the influence of the matrix effect. 30 The technique is based on extrapolation to an exhaustive extraction of the compounds through three or four cycles of consecutive extractions from the same sample.…”

Rosemary extracts are commercialized as natural antioxidants that delay the lipid oxidation process. Residual amounts of rosemary odour-responsible volatile compounds, such as borneol, camphor and verbenone, can remain in the final extract. The presence of these compounds may be undesirable when the extracts are used as food or cosmetic additives. In this paper a MHS-SPME method is proposed to quantify 10 rosemary odour-responsible compounds in a commercial solid rosemary extract. Multiple headspace solid-phase microextraction (MHS-SPME) is a recent technique proposed to eliminate the matrix effect on the quantitative analysis of solid samples. This technique performs few consecutive extractions from the same sample, and the total area corresponding to an exhaustive extraction is calculated as the sum of individual area values obtained from each extraction or by using an equation. The most influential variables of the extraction process, such as type of fibre, temperature and extraction time, were studied. Extraction was carried out using 2.5 mg solid extract and a divinylbenzene-carboxen-polydimethylsiloxane (DVB-CAR-PDMS) fibre at 55°C for 60 min; calibration was carried out using aqueous standard solutions containing 1% (v/v) ethanol at 40°C for 45 min. The features of the method were established using aqueous standard solutions. Precision was 4-15%, expressed as RSD, and the method allowed detection limits of 0.4 -47 ng for p-cymene and verbenone, respectively. Finally, the method was applied to analyse a rosemary solid extract, and verbenone (356 µ µ µ µ µg/g), borneol (190 µ µ µ µ µg/g) and camphor (136 µ µ µ µ µg/g) were found to be the most abundant compounds.

“…Recent advances include automatic systems that allow the coupling of the headspace sampler to the gas chromatograph injector, known as the purge and trap injection system (LEBOSSÉ; DUCRUET; FEIGENBAUM, 1997;WEZL;LANKMAYR, 2002;REYNIER et al, 2004;VILLBERG;VEIJANEN;GUSTAFSSON, 1998;KALJURAND;SMIT, 1994). The solid phase micro-extraction system is a recent modification introduced for the analysis of matrixes such as packaging materials (ZHANG; PAWLISZYN, 1993;EZQUERRO;PONS;TENA, 2003;PAWLISZYN, 1997).…”

“…SPME-GC has also been used to analyse a large number of analytes in a wide variety of matrices and has been successfully applied to the analysis of packaging materials. [22][23][24] In this study, the effect of different formulations, prepared using an autoemulsionable base cream, on multilayer packaging was tested. Thus, formulations at two concentration levels of each compound were introduced in sachets and stored at 40°C over a certain period of time.…”

In order to study the effect of several compounds on packaging stability, different cosmetic ingredients at two concentration levels were added to a NeoPCL® (Acofarma, Terrassa, Spain) water emulsion, and the preparations packed in sachets and stored at 40°C during 3 months. After that, the packaging was subjected to a T-peel test and headspace solid-phase microextraction gas chromatography mass spectrometry (HS-SPME-GC-MS) analysis. The HS-SPME-GC-MS analyses were performed using a 75 mm carboxen polydimethylsiloxane fi bre to check for the presence of the studied analytes in the inner layers. The study revealed that the presence of a phenyl and a hydroxyl group in the compound structure lead to an important loss of adhesion between packaging layers joined by an adhesive. The interaction between the cosmetic ingredient and the adhesive was proposed as the main cause of the loss of adhesion. However, extrusion-coating packaging was more susceptible to delamination, particularly with the volatile compounds.
