Positive Effect

Process approaches and intensification technological processes are integrated parts of available devices, which have a positive effect on the parameters of the obtained products. Nanoemulsions as delivery carriers are becoming more popular and there is a real need to increase the possibilities of formulation designing and engineering. Therefore, preparations of oil-in-water nanoemulsion with encapsulated cannabidiol (CBD) as oil phase were carried out in two ways: sonication method and two-stage high-pressure homogenization. The provided analysis showed spherical morphology and much larger sizes and polydispersity of nanoemulsions obtained by the sonication approach. The size of nanodroplets was from 216 nm up to 1418 nm for sonication, whereas for homogenization 128–880 nm. Additionally, it was observed that a proportionally higher percentage of surfactin resulted in a higher value of the Zeta potential. The formulations were found to be stable for at least 30 days. The in vitro experiments performed on human skin cell lines (HaCaT keratinocytes and normal dermal NHDF fibroblasts), and in vivo topical tests on probants established the biocompatibility of nanoemulsions with CBD. The last stage exhibits reduced discoloration and a higher degree of hydration by the selected systems with CBD and, thus indicating this nanoformulation as useful in cosmetics applications.

To investigate whether palmitic acid can be responsible for the induction of inflammatory processes, HaCaT keratinocytes were treated with palmitic acid at pathophysiologically relevant concentrations. Secretion levels of interleukin-6 (IL-6), tumor necrosis factor-α(TNF-α), interleukin-1β(IL-1β), NF-κB nuclear translocation, NF-κB activation, Stat3 phosphorylation, and peroxisome proliferator-activated receptor alpha (PPARα) mRNA and protein levels, as well as the cell proliferation ability were measured at the end of the treatment and after 24 hours of recovery. Pyrrolidine dithiocarbamate (PDTC, a selective chemical inhibitor of NF-κB) and goat anti-human IL-6 polyclonal neutralizing antibody were used to inhibit NF-κB activation and IL-6 production, respectively. Our results showed that palmitic acid induced an upregulation of IL-6, TNF-α, IL-1βsecretions, accompanied by NF-κB nuclear translocation and activation. Moreover, the effect of palmitic acid was accompanied by PPARαactivation and Stat3 phosphorylation. Palmitic acid-induced IL-6, TNF-α, IL-1βproductions were attenuated by NF-κB inhibitor PDTC. Palmitic acid was administered in amounts able to elicit significant hyperproliferation and can be attenuated by IL-6 blockage. These data demonstrate for the first time that palmitic acid can stimulate IL-6, TNF-α, IL-1βproductions in HaCaT keratinocytes and cell proliferation, thereby potentially contributing to acne inflammation and pilosebaceous duct hyperkeratinization.
