“…For all three types of formulation, the most intensive signals are connected with water molecule oscillation (~3000–3700 cm −1 ) and the presence of alcohols like glycerol, propylene glycol (hydroxyl group oscillations ~1500 cm −1 ). In the case of cream, there are also characteristic bands associated with aliphatic groups from fatty acids (~2900 cm −1 ) [ 26 ].…”

The skin is constantly exposed to external and internal factors that disturb its function. In this work, two nanosystems-levan nanoparticles and a surfactin-stabilized nanoemulsion were preserved (tested for microbial growth) and characterized (size, polydispersity, Zeta potential, and stability). The nanosystems were introduced in the model formulations-cream, tonic, and gel, and confirmed by TEM. The analysis showed that nanoemulsion has a spherical morphology and size 220–300 nm, while levan nanoparticles had irregular shapes independently of the use of matrix and with particle size (130–260 nm). Additionally, we examined the antiradical effect of levan nanoparticles and nanoemulsion in the prototype of formulations by scavenging DPPH (2,2-diphenyl-1-picrylhydrazyl; EPR spectroscopy). The model cream with both nanosystems and the whole range of products with nanosystems were evaluated in vivo for hydration, elasticity, smoothness, wrinkles and vascular lesions, discoloration, respectively. The cream improved skin condition in all tested parameters in at least 50% of volunteers. The use of more comprehensive care, additionally consisting of a tonic and gel, reduced the previously existing skin discoloration to 10.42 ± 0.58%. The presented prototype formulations are promising in improving skin conditions.

“…In last time, the increasingly used solution to the problem of degradation of polyethylene is its combination with natural polymers, such as starch, cellulose or gelatine [9,21]. The solution is based on the statement that the combination of a synthetic polymer (resistant to decomposition) with a natural polymer (prone to biodegradation) in one product will give a material whose chemical structure will partially degrade under the influence of biological factors, while its internal structure will be permanently damaged [29].…”

“…Unfortunately, after a relatively short time of use, it becomes extremely resistant to biodegradation, constituting a burden on the environment. The polyethylene's resistance to degradation results from the high molecular weight of this polymer and its content of antioxidants and stabilisers [9,10]. According to these authors, the addition of these substances protects polyethylene against oxidation already at the production stage.…”

Degradation of Polyethylene and Biocomponent-Derived Polymer Materials: An Overview

2019

View full text Add to dashboard Cite

The progressing degradation of the natural environment taking place over the last few decades and resulting from the systematically growing production of synthetic polymer materials led to the search for technological innovations aimed at producing environmentally friendly materials. Moreover, the increasing importance of sustainability promotes the development of bio-based and biodegradable polymers, sometimes misleadingly referred to as "bioplastics". Inability to degrade synthetic polymer materials and the problem of their persistence in the environment even for hundreds of years have caused the production of polymer materials with the addition of components that may accelerate their degradation more and more important in recent years. Additionally, the growing interest in environmental issues makes the requirements for new materials that will not significantly burden the environment higher. In Poland 29.1% and 26.8% of post-consumer polymer materials, respectively, were recovered and recycled, which means that up to 44.1% of post-consumer polymer materials were sent to municipal landfills. In 2017, for the first time in Poland, more plastics were recovered (55.9%) than stored (44.1%). However, by 2020, the level of energy recovery and recycling of post-consumer polymer materials in Poland should cover a total of 84.5%. When looking at the average values for Europe (recycling 31.1%, recovery 41.6%, storage 27.3%), it should be noted that Poland has much to catch up in this area and decisive actions should be taken to actually solve this problem. For this reason, it is extremely important to know the mechanisms responsible for the degradation of polymer materials and understand the interaction between these materials and abiotic and biotic factors that cause structural changes in polymers. Recent studies show that knowledge of the conditions determining the decomposition of polyethylene polymer materials and their impact on the natural environment is still insufficient. The literature reports reveal many contradictory theories, especially those that relate to the degradation of polymer materials in the soil environment. This study constitutes a comprehensive review of researches on (bio)degradation of polymer materials over the last decades, various methods of polymer structure modification to increase the degree of their degradability, as well as methods of recycling post-consumer polymer materials. Because there is a need to assess the performance of polymer innovations in terms of their biodegradability, especially under realistic waste management and environmental conditions, to avoid the unwanted release of plastic degradation products to the environment.

“…The spectral region from 700 to 1800 cm −1 was selected for comparison of the samples. The bands around 1743 and 1750 cm −1 were attributed to the characteristic carbonyl (C=O) stretch observed with skin and lipstick, respectively [36,37]. For IR characterization of the anthocyanins on the tape strips, the spectral region of 900-1160 cm −1 was assigned to the C-O stretching vibration of the sugar moiety of the glycosides present and to a lesser extent to the aromatic C-O stretching [38].…”

Ex Vivo and In Vivo Assessment of the Penetration of Topically Applied Anthocyanins Utilizing ATR-FTIR/PLS Regression Models and HPLC-PDA-MS

Anthocyanins are natural colorants with antioxidant properties, shown to inhibit photoaging reactions and reduce symptoms of some skin diseases. However, little is known about their penetration through the stratum corneum, a prerequisite for bioactivity. The aim was to investigate anthocyanin penetration from lipophilic cosmetic formulations through the skin using a porcine ear model and human volunteers. ATR-FTIR/PLS regression and HPLC-PDA-MS were used to analyze anthocyanin permeation through the stratum corneum. Penetration of all anthocyanins was evident and correlated with molecular weight and hydrophilicity. Lower-molecular-weight (MW) anthocyanins from elderberry (449–581 Da) were more permeable within the skin in both ex vivo and in vivo models (Kp = 2.3–2.4 × 10−4 cm h−1) than the larger anthocyanins (933-1019 Da) from red radish (Kp = 2.0–2.1 × 10−4 cm h−1). Elderberry and red radish anthocyanins were found at all levels of the stratum corneum and at depths for activity as bioactive ingredients for skin health.
