Artificial Neural Networks to Optimize Oil-in-Water Emulsion Stability with Orange By-Products.

ABSTRACT: The use of artificial neural networks (ANNs) is proposed to optimize the formulation of stable oil-in-water emulsions (oil 6% w/w) with a flour made from orange by-products (OBF), rich in pectins (21 g/100 g fresh matter), in different concentrations (0.95, 2.38, and 3.40% w/w), combined with or without soy proteins (0.3 and 0.6% w/w). Emulsions containing OBF were stable against coalescence and flocculation (with 2.4 and 3.4% OBF) and creaming (3.4% OBF) for 24 h; the droplets' diameter decreased up to 44% and the viscosity increased up to 37% with higher concentrations of OBF. With the protein addition, the droplets' diameter decreased by up to 70%, and flocculation increased. Compared with emulsions produced with purified citrus pectins (0.2 and 0.5% w/w), OBF emulsions exhibited up to 32% lower viscosities, 129% larger droplets, and 45% smaller Z potential values. Optimization solved with ANNs minimizing the droplet size and the emulsion instability resulted in OBF and protein concentrations of 3.16 and 0.14%, respectively. The experimental characteristics of the optimum emulsion closely matched those predicted by ANNs demonstrating the usefulness of the proposed method.

Project description:BackgroundApplication of topical moisturizers is an essential part of the management of atopic dermatitis (AD). Linoleic acid (LA), the most abundant fatty acid in the epidermis, and its derivatives have an essential role in the structure and function of the epidermal barrier, and their defects are prominent in AD. The aim of this study was to compare the efficacy and safety of two cosmetic products containing either LA or urea in patients with AD.Patients and methodsA total of 20 patients with AD who met the eligibility criteria and provided written informed consents were enrolled in this randomized, intra-individual split-body, single-center trial. Symmetrical lesions of patients were randomized for treatment with LA- or urea-containing water-in-oil (w/o) emulsions applied two to three times daily for 4 weeks. The efficacy of the two products was evaluated by local Scoring Atopic Dermatitis (SCORAD) of both lesions and also patient (or guardian) satisfaction. In addition, trans-epidermal water loss (TEWL), stratum corneum (SC) hydration, pH, sebum, temperature, erythema, melanin content, and ultrasonographic thickness and echo density of epidermis and dermis were measured before, and 2 and 4 weeks after, treatment.ResultsFour weeks of treatment with the LA-containing product resulted in a significant decrease in local SCORAD, TEWL, erythema, and echo density of dermis, as well as an increase in SC hydration compared to baseline. The urea-containing product also reduced the local SCO-RAD and echo density of dermis and increased SC hydration. In contrast to the LA-containing product, changes in TEWL and erythema were not significant. Moreover, the reduction of erythema was significantly higher in the LA-containing product-treated side compared to the urea-containing product-treated side (p = 0.006).ConclusionBoth LA- or urea-containing w/o emulsions can significantly improve barrier dysfunction and clinical severity of AD. In agreement with literature, it was confirmed that an LA-containing w/o emulsion exhibited erythema-reducing effects. Since emollients should be used on a regular basis, patients should choose a product by individual preference following recommendation by their dermatologists.
