The aim of this study was to produce an alcohol gel hand sanitizer containing green glycerol. Crude glycerol was purified using chemical and physical treatments. The sanitizer was prepared using 71.100 g of 99.3° GL ethanol, 28.0 g H2O, 0.5 g of Carboxypolymethylene [Carbopol 940® or Carbomer], 5 drops of triethanolamine (pH 5–7), and glycerol (1.5% w/w). The thermal behavior of the ethanol, carbopol, triethanolamine, glycerol, and alcohol gels were evaluated using Thermogravimetry and Differential Thermal Analysis. The apparent viscosity was obtained using a rotary viscometer. The determination of in vitro spreadability was achieved by an adaptation of the Knorst method. The ethanol content was measured by headspace gas chromatography using a flame ionization detector. The thermal behavior of the gels was influenced by the presence of glycerol, which confirms the possible network interactions formed. The relative densities of the samples were between 0.887 and 0.890 g/cm3. No alteration of the pH of the formulation resulted from the incorporation of glycerol. The apparent viscosities of the alcohol gels were greater than 20,000 cP. No alteration in the in vitro spreadability of the gel alcohol (530.6 mm2) resulted from the addition of glycerol. Hand sanitizer was produced using glycerol from a transesterification reaction. It represents an alternative use for the glycerol being produced in biodiesel processes. The product satisfied the requirements of WHO that preconize a formulation containing 1.45% glycerol as an humectant to protect skin against dryness and dermatitis.

As a result of the COVID-19 epidemic and the greater demand for alcohol gel sanitizers, the regulatory guidelines on sanitizer quality have been altered. The aim of this study was to produce green glycerol and an alcohol gel hand sanitizer. The ethanol content was measured by headspace (HS) gas chromatography (GC) using a flame ionization detector (FID). The thermal behavior of the gels is influenced by the presence of glycerol, which is an aspect that confirms the possible network interactions formed. The relative densities of the samples were between 0.887–0.890 g/cm³. The incorporation of glycerol did not significantly alter the pH of the final formulation, which was near neutrality. Both alcohol gels exhibited a high average apparent viscosity, greater than 20,000 cP, with no statistically significant difference between them (p > 0.05). The addition of glycerol did not change the in vitro spreadability of the gel alcohol, which remained at 530.6 mm² for both samples.

“…With the long-term consumption boom and the continuous emergence of various new products, marking or patterning on materials has become more common and important than ever, used to distinguish, classify, convey information, and decorate . In ancient times, people first discovered that inks could be printed on paper, bamboo, and metal. , Later, with the development of technology, clay printing, cork carving, and color-changing methods appeared successively. − Although modern production lines and equipment optimize the flow of the traditional printing process, it still has some shortcomings. Generally, the processing technology of the conventional printing method is complicated, time-consuming, inefficient, and environmentally unfriendly. , Therefore, in consideration of adapting to rapid consumption, people always try to develop more advanced technology to replace the conventional.…”

In this study, new core–shell microspheres for polymer laser direct writing (LDW) were successfully designed and prepared by a facile one-step microemulsion method. The color-changing core–shell microsphere consists of a SnO2 “core” which can absorb near-infrared (NIR) laser energy and a polyphenylene oxide (PPO) “shell” which can be easily carbonized at high temperatures. Owing to the unique core–shell structure, the SnO2@PPO microsphere remarkably enhanced the polymer LDW performance. SEM, TEM, and EDS indicated microspheres were regular spheres with an average size of 15.1 μm. Raman spectroscopy and XPS revealed that the SnO2 absorbed NIR laser energy to cause instantaneous high temperatures, leading to the carbonizing of the PPO shell. Thus, the color-change mechanism of the polymer during NIR LDW was confirmed as the formation of amorphous carbon by high-temperature carbonization. We believe these novel microspheres will have wide applications in the field of polymer LDW. Besides, the concept of preparing core–shell microspheres by the one-step microemulsion method provides a new idea for designing color-changing microspheres.
