Grape pomace is a by-product abundant in phenolic compounds that can be used the food, cosmetic, and pharmaceutical industries. For efficient extraction of such compounds, an aqueous solution non-ionic surfactant Brij S20 was applied as green medium, optimization performed using surface response methodology. The effects four independent factors (surfactant concentration, time, pH, solvent-to-material ratio) were evaluated, total content (TPC), DPPH radical inhibition, selected polyphenol...

The present study is concerned with the determination of critical micelle concentration (cmc) mixed micelles sodium dodecyl sulfate one five nonionic surfactants (Triton X-100, Tween 20, 60, 80 or 85) from conductance measurements. Based on calculated values ? parameters we have noticed that SDS-nonionic mostly showed strong synergistic effect. It was found mainly longer and more hydrophobic tail show stronger interactions part SDS, thus expressing synergism. In SDS-Tween binary system...

Knowledge of physicochemical parameters mixed micelles is important in order to develop drug delivery systems with required characteristics. Investigated bile salts and Tweens are relatively nontoxic surfactants, extensively studied as biocompatible colloidal carriers. The micellization behavior binary anionic–nonionic surfactant mixtures built sodium cholate or deoxycholate one two (Tween 20 Tween 60) was investigated by conductivity surface tension measurements. results the study have been...

Background: Zinc oxide paste is traditionally compounded and applied in the therapy of various skin conditions. However, prolonged use talc, usually present zinc pastes, may pose health risks due to potential contamination with asbestos quartz, highlighting need for alternative excipients. This study aimed examine effects starches from botanical sources their particle size on rheological absorption properties paste. Methods: Eight formulations were prepared, containing 25% indifferent...

In order to develop colloidal drug carriers with desired properties, it is important determine physico-chemical characteristics of these systems. Bile salt mixed micelles are extensively studied as novel delivery The objective the present investigation and characterize nonionic (Triton X-100) or anionic (sodium lauryl ether sulfate) surfactant having oxyethylene groups in polar head following bile salts: cholate, deoxycholate 7-oxodeoxycholate.The micellization behaviour binary...

There is a growing need for natural ingredients that could be utilized the production of food, pharmaceutical, and cosmetic emulsions. Soy protein acid hydrolysate (SPAH) plant-based additive used in food industry mainly as flavor enhancer. For purpose this work, however, it was mixed with well-known polysaccharide, xanthan gum (XG), to produce stable 30% (w/w) sunflower oil-in-water emulsions using rotor-stator homogenizer. In order assess emulsifying properties SPAH its mixtures XG,...

Salts of bile acids are steroid amphiphilic compounds which form micelles consisting 2–12 monomer units. In nature, the formation mixed with phospholipids (gall bladder) increases capacity salts to solubilize cholesterol. Oxo derivatives special research interest because their lower membrane toxicity compared corresponding OH analogues. view fact that anions oxo have hydrophobicities, it was interesting study and hydrophobic nonionic cosurfactant Tween 40. With this aim, critical micelle...

Background: Natural antioxidants, such as grape pomace polyphenols, can be extracted by a surfactant-based green technology and incorporated into various emulsions. Therefore, this work aimed to investigate the physical stability rheological characteristics of oil-in-water emulsions stabilized with poloxamer 407 (P407) its mixtures low-molecular-mass surfactants Brij S20 (BS20) Tween 60 (T60). Also, influence polyphenolic extracts on was examined. Methods: Grape polyphenols were aqueous...

Rinse-off cosmetic products, primarily shampoos, are frequently implicated in the onset of allergic contact dermatitis (ACD) caused by alkyl glucosides (AGs). AGs increasingly popular surfactants and known allergens. Glucoside-induced ACD was most observed with shampoos skin-cleansing products both consumer occupational settings. Thereby, studies have shown that atopic individuals susceptible to ACD. Also, several investigations indicated sensitive skin might be more prone allergies. This is...

Alpha hydroxy acids (AHAs) are used in dermatology for topical treatment of skin disorders. Some regulatory bodies, including Food and Drug Administration (FDA), recommended labeling cosmetic products with sunburn alerts proposed limitations regarding concentrations AHAs products. In addition, The Cosmetic Ingredient Review (CIR) Expert Panel 10% as the maximal safe concentration. With a rapidly increasing trend online purchasing products, it is important that their labels convey necessary...

Abstract Owing to their ability adsorb at interfaces, polysorbates have an important role in pharmaceutical formulations. Because surfactant mixtures can improved properties, it was hypothesized this work that introduction of poloxamer 407 aqueous solutions (polysorbate 60, polysorbate 80 and 85) might improve surface properties. Nonideal behavior the air/water interface investigated using Rosen's model recently introduced method for determination quantification nonideal regarding tension...

Abstract The aim of this study was to investigate micellar and self‐assembly properties four sodium salts naphthenic acid mixtures by determination comparative analysis their critical micelle concentration values at seven different temperatures ranging from 10 40 °C using spectrofluorophotometric measurements. It concluded that fractions having the lowest percentage aliphatic structures give least flexible micelles due sterically rigid structure cyclic side chains, what makes them difficult...

Rheology is a science that deals with the movement and deformation of materials, while interfacial rheology branch focuses on study mechanical properties fluid interfaces, such as liquid-liquid liquid-gas interfaces. The behavior interfaces differs significantly from bulk standard rheological measurements materials cannot adequately describe their properties. Interfacial specialized approach to viscoelasticity tension at liquid provides valuable insight into intermolecular interactions...
