Tansy (Tanacetum vulgare) is a common plant used in folk medicine for digestive problems, fevers, and migraines; against parasites; as an insect repellent. The active substances essential oil are responsible its antimicrobial antioxidant activity. Thus, tansy (TO) was added to alginate films fabricate materials with antibacterial properties food packaging. Sodium glycerol TO were tested terms of structure, mechanical, thermal, antioxidant, properties. structure the examined using SEM...

The excessive presence of single-use plastics is rapidly degrading our natural environment on a global scale due to their inherent resistance decomposition. Wet wipes used for personal or household purposes contribute significantly the accumulation plastic waste. One potential solution address this problem involves developing eco-friendly materials that possess ability degrade naturally while retaining washing capabilities. For purpose, beads from sodium alginate, gellan gum, and mixture...

The objective of this study was to develop three-dimensional collagen/gelatin/hydroxyethyl cellulose composites in combination with gelatin or collagen-gelatin loaded microspheres. Microspheres were prepared by an emulsification/crosslinking method. A 1-Ethyl-3-(3-dimethyl-aminopropyl)-carbodiimide (EDC) and N-hydroxysuccinimide (NHS) mixture used as a crosslinking agent for the obtained materials. structure materials studied using scanning electron microscopy (SEM) infrared spectroscopy....

Alginate films plasticized with glycerol and enriched in raspberry and/or black currant seed oils were prepared via casting solution techniques. The intention was to create active for food packaging where antioxidants a film would deactivate oxidants packed product or its surroundings, improving conditions inside extending the shelf life of such product. materials characterized by physicochemical, spectroscopic, mechanical, water vapor transmission (WVTR), antioxidant activity analysis....

Because consumers are nowadays focused on their health and appearance, natural ingredients novel delivery systems one of the most developing fields pharmacy, medicine, cosmetics. The main goal this study was to design, prepare, characterize composite materials obtained by incorporation microspheres into porous polymer consisting collagen, gelatin, hydroxyethyl cellulose. Microspheres, based gellan gum xanthan with encapsulated Calendula officinalis flower extract, were produced two methods:...

Gelatin/polyvinylpyrrolidone/hydroxyethyl cellulose/glycerol porous matrices with microspheres made of sodium alginate or pectin and were produced. A surfactant was loaded into these microparticles. The characterized using optical microscopy, scanning electron microscopy SEM, laser diffraction particle size analyzer. For the matrices, density, porosity, swelling capacity, dissolution in phosphate saline buffer determined mechanical, thermogravimetric studies applied. results showed that...

The study was undertaken to evaluate the effect of filler (kaolin) modification with silane coupling agents on properties polyethylene (HDPE Hostalen ACP 5831) composites.Powder mineral fillers are added polymers modify latter and reduce cost their production.A very important factor is dispersion in polymer matrix.Kaolin modified 3-methacryloxypropyltrimethoxysilane pure kaolin were characterised by surface area, pore size, water absorbing capacity, paraffin oil bulk density, scanning...

As a facial skin condition, oily causes cosmetic problems, such as large pores, shiny appearance, and the feeling of greasiness heaviness. Furthermore, extensive sebum production leads to common disorders acne vulgaris or seborrheic dermatitis. This study investigated efficacy control tonics containing Juniperus communis fruit oil, Pelargonium graveolens niacinamide. The effects niacinamide on excretion rates were using Sebumeter®. Sebum measurements (Sebumeter® SM 815, Courage &...

The use of natural active substances and the development new formulations are promising directions in cosmetic pharmacy industries. primary purpose this research was production microparticles based on whey protein isolate (WPI) calcium alginate (ALG) containing Calendula officinalis flower extract their incorporation into films composed gelatin, WPI, glycerol. Both swollen dry were studied by optical microscopy sizes measured. Water absorption microparticles, loading capacity, release...

Porous three‐dimensional collagen/chitosan scaffolds combined with poly (ethylene glycol) (PEG) and hydroxyapatite were obtained through a freeze‐drying method. Physical cross‐linking was examined by dehydrothermal treatment. The prepared materials characterized different analyses, eg, scanning electron microscopy (SEM), measurements of porosity swelling, mechanical properties, resistance to enzymatic degradation. their swelling ratio decreased the addition hydroxyapatite. Moreover, after...

The effect of kaolin modification silane coupling agents on the properties polyethylene composites This paper shows results using modified by in HDPE composite and surface modifications fillers composites. In first stage pure was subjected to a number tests order determine backfill density, water paraffin oil absorbability, area pore volume, morphology their grains, thermal analysis FT-IR spectroscopy. second composites, which were moulded into samples that could be further tests, produced....

Human skin has protective functions and it is a barrier that protects the interior of body from harmful environmental factors pathogen penetration. An important role also to prevent loss water if damaged, amount emitted internal environment increased. Therefore, crucial recovery maintenance epidermal integrity. The aim current work was encapsulate Calendula officinalis flower extract in gelatin microspheres then incorporation into thin polymeric films made sodium alginate or mixture starch....

The mixtures of hyaluronic acid and poly(vinyl alcohol) were prepared to obtain new bioartificial materials. HA easily degrades after injection the human body, so, these polymers can lead materials with modified degradation behavior. It was also tested whether UV-radiation could be used as a sterilizing agent for blends. FTIR analysis showed that hydrogen ester bonds are formed between PVA. values surface free energy point out polar groups involved in creation H-bonds. UV-irradiation caused...

The blends of synthetic and natural polymers are extensively investigated as materials for medical applications. Synthetic component usually ensures appropriate mechanical physical properties while biopolymer improves biocompatibility the material. In our work, we decided to use poly(vinyl alcohol) (PVA)—water-soluble, chemically stable, elastic polymer elastin—a fibrous protein present in extracellular matrix connective tissues. aim work was study influence UV light on spectroscopic...
