“…The presence of a broad peak at 3312 cm −1 can be ascribed to the O–H stretching vibrations. SW and other vegetable waxes are comprised of long-chain fatty acids and saturated hydrocarbons [ 60 ]. Natural waxes consist of sterols, sterol esters, and long-chain alcohols, which give rise to hydroxyl group stretching vibrations [ 61 ].…”

Emerging natural-based polymers and materials progress and new technology innovations open the way for unique food products with high nutritional value development. In this regard, oleogel may be essential in replacing fatty acids from food products. In this study, we researched the effects of varied soy lecithin (SYL) concentrations on the various physicochemical characteristics of soy wax (SW)/refined soybean oil (RSO) oleogels. These oleogels had a soft texture. The microscopic analysis of the oleogels suggested that the thickness, length, and density of the wax crystals (needle-shaped) varied as the SYL content was changed. Colorimetric analysis indicated that the oleogels were slightly yellowish. FTIR spectrometry helped analyze the functional groups of the raw materials and the oleogels. All the functional groups present in the raw materials could be accounted for within the oleogels. The only exception is the hydrogen-bonding peak in SW, which was not seen in the FTIR spectrum of the oleogels. It was found that at a critical SYL content, the oleogel showed a stable and repeatable wax network structure. This can be described by the presence of the uniformly distributed fat crystal network in the sample. The DSC analysis revealed that the oleogel samples were thermo-reversible, with their melting and crystallization temperatures ~43 °C and ~22 °C, respectively. In gist, it can be concluded that the incorporation of SYL can impact the color, wax crystal network characteristics, thermal characteristics, and mechanical characteristics of the oleogels in a composition-dependent manner.

“…Candle wax is IOP Publishing doi:10.1088/1757-899X/1252/1/012013 2 one of the potential materials for storing energy using wax phase change. Several authors have been investigated the thermal conductivity of wax for its perspective use in thermal energy storage [7][8][9]. The paper is aimed at investigation of the thermal parameters of wax material of the commonly used type of candle by using thermal analysis methods.…”

Indoor air quality is a key aspect of people staying inside buildings. Combustion processes have been identified as one of the most important sources of pollutants in the indoor environment. Proper HVAC design must account for all sources and variations in their intensity, such as also the burning of candles, which produce not only increased amounts of carbon dioxide as a result of the combustion of the organic matrix, but also often dangerous organic substances. On the other hand, the candle burning represents an energy source as well. This article deals with the study of thermal decomposition of selected candle material using methods of thermal analysis - thermal gravimetric analysis (TG) and differential scanning calorimetry (DSC). The wax material analyzed was identified as a mixture of palm stearin and paraffin. During the candle wax material heating, the energy up to 772.6 J per 1 g of material can be released in dependence on the heating rate.
