“…In results that mirror those of Tavares and Lancas, the authors concluded that SFC was better suited for "nonvolatile" hydrocarbons. Planeta et al described an interesting application of SFC to the characterization of natural waxes in objects of art (111). The sensitive packed-capillary method is an important tool in art restoration efforts.…”

Development of packed capillary columns using carbon dioxide slurriesA modified procedure for the preparation of packed capillary columns by the use of supercritical or liquid carbon dioxide slurries is proposed. This technique removes the problems arising from sudden and rapid movement of sorbent suspension at the beginning of the filling process. The parameters influencing the packing process (temperature, pressure, and restrictor that controls the flow rate of CO 2 ), have been optimized. The columns prepared under optimized conditions exhibit high efficiency (average value of the reduced plate height h 9 ca. 2.2), and long term stability. An example of the SFC separation of polydimethylsiloxanes in silicone oil is presented.

“…Waxes are categorized as lipids as they are non-polar and only dissolved in organic solvents. The main constituents of wax are hydrocarbons, medium chain length of monoesters-diesters-triesters of fatty acids, long-chain, and free long-chain alcohols, aldehydes, sterols, ketones and ß-diketones, triterpenols, and triterpenic acids [7]- [8]. The use of naturally sourced waxes such as paraffin has raised environmental concerns as they are non-sustainable and non-biodegradable [9].…”

The typical of beeswax, dammar, rosin, paraffin, and microcrystalline wax. batik wax compositions used in Malaysia consist of various blends This study aims to characterize soy wax/beeswax blends’ structural, thermal, strength, and mass loss properties as potential alternative batik wax compositions. The Fourier transform infrared spectroscopy (FTIR) results showed that the additions of beeswax (wt%) into soy wax resulted in possible chemical interaction for the esters (C=O stretching and C-H bending vibrations), hydrocarbons (CH2 scissor formation), and cholestral esters (C=O stretching vibrations). The thermal profile obtained via differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA) respectively revealed an increase in peak melting temperature and reduced thermal stability of the blends with further increments of beeswax. In addition, beeswax enhances the compression strength by 150% but did not have any significant impact on the modulus of the blends. E valuation of the mass loss test suggested that beeswax in the range of 40 wt% to 60 wt% can be considered as alternative batik resist material due to its moderate leaching tendency. Future works shall be conducted to evaluate the performance of these wax compositions against other batik wax criteria and the feasibility of printing these waxes using an in-house designed batik printer.
