Surfactants are important ingredients of personal care products and household products. The main characteristic these compounds is to decrease the surface tension solvent resulting many properties such as contact angle, foam etc. coexistence other in product may affect surfactants. One components contained almost every sodium chloride. aim this work was determine effect salt on some usage cocamidopropyl betaine (CAPB). From our experiments it shown that added chloride aqueous solutions CAPB...
Liquid soaps are the basic cosmetics used to clean skin of hands. Frequent hand washing prevents viral contamination but may damage skin's hydro-lipid layer, leading various types irritation. Therefore, four liquid soap formulas were developed with three amphoteric surfactants: Cocamidopropyl Betaine (LS II), CocamidopropylHydroxysultaine III), and newly synthesized Evening PrimroseaamidopropylSulfobetaine IV). We evaluated irritating potential (zein number, bovine albumin test) cytotoxicity...
Abstract Sulfobetaines belong to the group of zwitterionic surfactants. They are electroneutral salts, which have in same molecule, two ionic centers with different charge. Due specific structure they exhibit excellent properties such as good solubility water and detergency. In this paper we present surface adsorption parameters sulfobetaines water/air systems. From isotherms CMC value, tension pressure at well efficiency were determined. Physicochemical analyses data allowed for further...
Three new heterogemini sulfobetaines and their chloride salts were synthesised. The interfacial activities of the obtained chlorides in aqueous solution studied by equilibrium dynamic surface tension measurements. critical micelle concentration, excess minimum area per surfactant molecule standard Gibbs energy adsorption as well lifetime diffusion coefficient determined. properties these compounds significantly depend on length alkyl chain. concentration decreases with increasing chain...
A novel approach using a zwitterionic sulfobetaine-based surfactant for the synthesis of spherical copper oxide nanoparticles (Cu2O NPs) has been applied. For first time, N-hexadecyl-N,N-dimethyl-3-ammonio-1-propanesulfonate used as stabilizer to control size and morphology Cu2O NPs. Several techniques, such transmission electron microscopy (TEM), X-ray diffraction (XRD), fluorescence spectroscopy, are investigate size, structure, optical properties synthesized nanocrystals. The results...
Abstract A new method for the preparation of heterocyclic amine surfactants based on sulfobetaines is proposed. Interfacial activities obtained in aqueous solution were studied by surface tension measurements. The critical micelle concentration, excess minimum area per surfactant molecule, and standard Gibbs energy adsorption determined. properties these compounds depend significantly alkyl chain length. Alkyl length also affects biological surfactants, determining inhibitory concentration...
Chromium(III) is considered as an essential element playing a role in carbohydrate and lipid metabolism, various chemical forms of this are widely used dietary supplements. A new trinuclear chromium(III) glycinate complex [Cr(3)O(NH(2)CH(2)CO(2))(6)(H(2)O)(3)](+)NO(3)(-) (CrGly), analogue Cr3 (trinuclear Cr(III) propionate complex) has been synthesized potential source supplementary Cr. In study, we evaluated the acute toxicity class CrGly Wistar rats applying OECD 423 procedure. Male female...
In the present study, influence of chromium(III) complexes (acetate, chloride, glycinate, histidinate, lactate and propionate) on insulin binding signal transduction [phosphorylation tyrosine serine in receptor substrate (IRS)-1] was investigated vitro using three experimental models: isolated rat liver membranes cultured mouse C2C12 myoblasts or 3T3-L1 preadipocytes. The examined did not elevate to membranes. Moreover, chromium lactate, acetate propionate diminished specific insulin....
Abstract Fourteen new sulfobetaines with N-alkylmorpholinium moiety have been synthesized using correspording N-alkylmorpholines and propanesultone or butanesultone. Their interfacial activities in aqueous solution were studied by equilibrium dynamic surface tension measurements. Surface measurements provide information about the excess concentration, minimum area per surfactant molecule, critical micellar concentration (CMC) standard Gibbs energy of adsorption. The adsorption properties...
The purpose of the study was to applicate new synthesized zwitterionic surfactants as hair shampoo components. Hair shampoos formulated for contained newly sulfobetaines at a concentration 2%. above additives were evaluated determine their effect on dynamic viscosity, texture, yield stress, foaming properties and surface tension aqueous solutions. viscosity sulfobetaine-enriched ranged between 6,000 21,000 mPa·s, which ensures required application products. stress in three prototypical equal...
Quaternary ammonium compounds (QACs) are classified as cationic surfactants, and known for their biocidal activity. However, modes of action thus far not completely understood. In this study, we synthesized a gemini QAC, PMT12-BF4 found that it exerted unsurpassed broad-spectrum antifungal activity against drug susceptible resistant Candida albicans, other pathogenic fungi, with minimal inhibitory concentration (MIC) at 1 or 2 μg/mL. These results indicated used mode distinct from current...
An attempt to assess recesses on the rake face after milling wood laminated with polyvinyl acetate (PVA) based glue is presented. Several analytical methods were employed explain tribo chemical corrosion reactions (TCCR) leading formation of specific form wear face. By means thermal gravimetric analysis it was confirmed that cobalt and tungsten carbide—main components sintered carbide cutting edge—were subjected intensive TCCR. Although an increase in stability PVA modification evidenced,...
This work presents a synthesis method for new surfactants based on lactose. The compounds obtained belong to the homologous series of O-β-D-Galactopyranosyl-(1→4)-N-alkyl-(3-sulfopropyl)-D-glucosamine hydrochloride, containing 12 and 14 carbon atoms in alkyl chain, they may serve as an example cationic surfactants. newly synthesized exhibit good surface properties, low value CMC (Critical Micelle Concentration) wetting properties. These surfactants' ability produce foam is considerably...
