“…2(b)), the DSD of E3 hardly changed in the study time, which was supported by the analysis of variance (ANOVA) results. This is due to the fact that the surfactant successfully protected the interface against every destabilization mechanism, such as coalescence or Ostwald ripening 22 . In addition, this effect could be observed for the E2 emulsion.…”

BACKGROUND: Nanoemulsions formulated with citric essential oils are currently of interest because of their physical and chemical properties and multiple applications in areas such as the food industry or agrochemicals. These are thermodynamically unstable and have almost Newtonian flow behaviour, but a suitable formulation allows systems to be obtained with good physical stability and rheological properties. The addition of pectin makes this possible. In this work, food nanoemulsions formulated with pectin, orange essential oil (5 wt%), and Tween 80 were obtained by microfluidization. First, the effect of Tween 80 concentration from 1 to 5 wt% on emulsions without pectin was evaluated. Then, pectin was added to the most stable nanoemulsion obtained and two variables were studied: the pectin solution concentration (from 2 to 6 wt%) and the pectin/emulsion ratio (1:1 or 2:1) at a fixed pectin concentration. RESULTS: Rheological, laser diffraction, and multiple light scattering techniques were employed to determine the content of Tween 80 that results in the most stable nanoemulsion without pectin, which was 3 wt%. In addition, these techniques were used to determine the structure and physical stability of the nanoemulsions containing orange essential oil and pectin. The results obtained showed that the emulsions containing 2 wt% pectin were destabilized before 24 h. Furthermore, the emulsion with 6 wt% pectin and a 2:1 pectin/ emulsion ratio showed the highest viscosity and the lowest mean diameters, and therefore the greatest stability.CONCLUSION: This work extends the knowledge of formulation of nanoemulsions and using essential oils.

“…Sebagian besar karakteristik biodiesel yang diemulsi dapat diperbaiki dengan memperhitungkan berbagai faktor selama proses persiapan, seperti: karakteristik surfaktan dan co-surfaktan (Balcan et al, 2014), intensitas dan durasi metode yang digunakan (Elsanusi et al, 2017), rasio volume (Fresneda et al, 2020) dan sifat fisik (viskositas dan tegangan permukaan) dari masingmasing fase (Kumar et al, 2020), dan pemanasan minyak nabati (Melo-Espinosa et al, 2015). Balcan et al 2014 menunjukkan bahwa pada suhu ruang, air adalah pelarut yang lebih baik daripada minyak untuk surfaktan nonionik, tetapi pada suhu tinggi merupakan pelarut yang buruk.…”

“…Considering the last key point, it is also necessary to consider the quality of the final product, as this will have a considerable impact on the economic and social domains. Several studies have described different strategies towards sustainability, such as the exploitation of local and low-cost natural ingredients (e.g., pine nut derivatives and rice water), the production of new and/or improved raw materials through green chemistry, and the use of industry redundancies and/or wastes (e.g., spent coffee grounds and cork) [1,[3][4][5][6][7][8][9][10]. Nevertheless, the inclusion of this type of ingredient requires further investigation concerning the physicochemical impact of its use [1].…”

With the increasing debate on sustainability, there is a strong market trend to formulate more sustainable products for topical application. Several studies emphasize the potential applications of natural, organic, or green chemistry-derived ingredients, but comparative studies between conventional ingredients and sustainable alternatives are lacking. This type of study is considered an excellent baseline and time-saving strategy for future studies. In addition, one of the main challenges of replacing ingredients by sustainable alternatives in topical vehicles is to maintain high-quality products. Thus, the main goal of this research study was to create a well-defined strategy supported by specific experimental data for the development of sustainable topical vehicles with high-quality standards. The study was designed to evaluate the effects of replacing conventional ingredients (e.g., hydrocarbons, silicones, and preservatives) by sustainable ones on the physical, chemical, and microbiological features of topical emulsions. Additionally, in vivo assessment studies were performed to evaluate the safety, biological efficacy, and sensorial aspects of the developed formulations. The results obtained showed that the replacement of ingredients by sustainable alternatives has an effective impact on the physicochemical and structural properties of the emulsions, mainly on their rheological behavior. However, using appropriate strategies for ingredient selection and rheological adjustment, it is possible to overcome some barriers created by the use of natural raw materials, thus developing appealing and high-quality sustainable topical vehicles.
