Cloud point extraction is developed using a low viscosity surfactant (Sylgard 309) coupled with HPLC-UV. It is a simple method for extraction of parabens in various samples. At the optimum conditions, the method developed achieves limit of detection and extraction recoveries in the range of 0.01 ppm -0.02 ppm and 68.5% -119.3%, respectively. Linearity of the calibration curves in the range of 0.2-1.0 mg/L. The correlation coefficient are achieved between 0.9995-0.9999. Each replicated samples are spiked with 1 mg/L of parabens. The results indicate that surfactant Sylgard 309 has a great potential for the extraction of organic pollutant in various samples.Keywords: cloud point extraction, parabens, sylgard 309, simple method for extraction Abstrak Pengekstrakan titik awan dibangunkan menggunakan surfaktan yang mempunyai kelikatan yang rendah (Sylgard 309) digabungkan dengan KCPT-UV. Ini merupakan satu kaedah yang mudah untuk pemisahan paraben dalam pelbagai jenis sampel. Pada keadaan yang optimum, kaedah yang dibangunkan ini boleh mencapai had pengesanan dan perolehan semula pengekstrakan dalam julat 0.01 ppm -0.02 ppm dan 68.5% -119.3%. Pekali korelasi yang dicapai adalah dalam julat 0.9995-0.9999. Larutan piawai yang ditambahkan dalam sampel iaitu 1mg/l paraben dalam setiap sampel replikat. Keputusan kajian menunjukkan bahawa surfaktan Sylgard 309 mempunyai potensi yang besar untuk diterokai bagi pengekstrakan pencemar 365rganic dalam pelbagai sampel.

“…The determination of BA and parabens can be carried out by HPLC (Saad et al 2005;Mroueh et al 2008;Petronela and Elena 2009;Khosrokhavar et al 2010;Tawalbeh et al 2014), capillary electrophoresis (Tang and Wu 2007). The analysis of BHA and BHT can be done with liquid chromatography-mass spectrometry (Lee et al 2006), nonisothermal pressurized-differential scanning calorimetry (Dunn 2005), gas chromatography (Yang et al 2002), and square-wave voltammetry (Medeiros et al 2010).…”

Screening of caffeine, preservatives and antioxidants in dairy products available in Bangladesh using an RP-HPLC method

et al. 2016

Background: The aim of this current study was to investigate the presence and to determine the contents of caffeine, preservatives and antioxidants in dairy products available in Bangladesh, one of the alarming countries in terms of food security. As high as 41 marketed dairy products, of both locally and internationally manufactured, were collected from local markets of Dhaka, Bangladesh in mid-2013 and then analyzed using an RP-HPLC method to determine the contents of caffeine, benzoic acid, propylparaben, butylparaben, butylated hydroxyanisole and butylated hydroxytoluene. The evaluation was performed using a C 18 column (150 mm × 4.6 mm i.d., 5 μm particle size) with a gradient flow rate of acetonitrile and diluted sulfuric acid (0.002 M) as mobile phase from ratio 15:85 to 80:20 (%v/v) at a flow rate of 2.0 ml/min at 265 nm. Results: The retention times of CF, BA, PP, BP, BHA and BHT were found about 3.6, 11.6, 13.0, 13.3, 13.6 and 16. 7 min, respectively. Results revealed that BA was found in 17.1 % of the products within the concentration range of 11~2067 mg/L; among these, 42.9 % products exceeded the allowable limit of 300 mg/L set by JECFA. Moreover, 14.6 % products showed positive response to CF at a concentration of 10~18 mg/L, which was well below the tolerance limit (<200 mg/L) set by FDA. However, none of these investigated dairy products were found to contain any detectable amount of PP, BP, BHA or BHT. Conclusion: Presence of excess amount of BA in dairy products, which are one of the most favorite healthy food items for all generations, can easily jeopardize public health sector. Moreover, CF was found in some CF-free products, which is also an alarming issue to be considered seriously to prevent the future occurrence of it.

“…For example, there are a lot of reports about harmful substances being prohibited or restricted in cosmetics. They could be detected through instruments analysis, including carcinogens-N-nitroso-diethanolamine [1], formaldehyde [2], preservatives [3] hormone [4], antibiotics [5], phenolies [6] and so on.…”

“…Many methods to detect specific components [1,[2][3][4][5][6] and heavy metals of cosmetics were reported in lots of literature. For example electrochemical detector detection (EC) [8], cold vapor atomic absorption spectrometry (CVAAS) [8,9], atomic emission spectroscopy (AES) [10], and inductively coupled plasma mass spectrometry (ICP-MS) [11,12], and so on.…”

An analysis method based on multi-instruments analysis technique coupled solvent extraction to determine compositions of unknown cosmetic were established. The multi-instruments involve high-performance liquid chromatography (HPLC), X-ray diffraction (XRD) and Fourier transform infrared (FTIR). The cosmetic sample was separated and enriched into 4 fractions by the solvent extraction. The compounds were defined as mercuric ammonium chloride, liquid paraffin, etc.
