Abstract:

The aim of this study was to prepare matrix beads made of enteric polymer, Eudragit® L, metronidazole and various amounts of cetyl alcohol (0, 0.1 and 1%). Eudragit® L, metronidazole and cetyl alcohol were dissolved in acetone and then extruded into dichloromethane. The influence of amount of cetyl alcohol on floating and drug release behavior of matrix beads of Eudragit® L was investigated. The results showed that, after extruding, cetyl alcohol dissolved out from the beads already formed, resulting in a porous structure. Thus, the beads can float in simulated gastric fluid for more than 8 hours. Different amounts of cetyl alcohol had a slight effect on the drug release. However, the increased amount of cetyl alcohol in the formulations significantly sustained the drug release while the beads remained floating. The results suggest that Eudragit® L beads could be used as a carrier for intragastric floating drug delivery.

Abstract:

This paper presents the results of experiments on the control of ammonia volatilization from flooded rice by the use of surface films of organic compounds.Preliminary experiments in evaporation pans, 1.2 m diameter, buried in an upland field of mown pasture, showed that ammonia volatilization from water could be reduced by applications of surface films of long chain alcohols; the effect increased with increasing length of carbon chain.The most effective way to add the film was to dissolve the long chain alcohol in ethanol, and to distribute the solution on the surface of the water.In an experiment in a flooded rice field, additions of cetyl alcohol dissolved in ethanol significantly reduced the rate of ammonia emission and total nitrogen loss. The effect was short-lived, probably due to microbiological decomposition of the cetyl alcohol and dispersion of the surface film by strong winds.

Abstract:

Cholesteryl cetyl carbonate (CCC) was synthesized from cetyl alcohol and cholesteryl chloroformate. Cholesteryl cetyl carbonate mixture (CCCM) was obtained from the reaction. CCCM was purified by liquid-liquid extraction and flash column chromatography. Thermotropic liquid crystal was formed in both pure CCC and CCCM. CCCM is composed of cholesterol, cetyl alcohol and CCC (30:20:50, weight ratio). FTIR and NMR were employed to confirm the functional groups of CCC. Thermal properties of CCC were determined by DSC and polarized light microscope. The phase transition from solid crystal to smectic appears at 42 °C, smectic to nematic appears at 54 °C and nematic to isotropic liquid appears at 73 °C. Indomethacin (IDM) could be incorporated into CCC and properties of CCC-IDM mixture stayed as liquid crystalline phase.

Abstract:

Injury and mortality after exposure to 100% oxygen can be diminished by surfactants that may operate by mechanisms other than those responsible for surface tension effects. We tested the hypotheses that 1) synthetic surfactant and its components function as antioxidants in vitro and 2) decrements in hyperoxic injury after treatment with a surfactant and its components are associated with decreases in oxidative stress to the lung. A synthetic surfactant (Exosurf) and its non-surface-active components tyloxapol and cetyl alcohol were incubated in an iron-containing hydroxyl radical-generating system to determine their abilities to prevent oxidation of deoxyribose. Doses of tyloxapol, cetyl alcohol, and artificial surfactant diminished the absorbance of thiobarbituric acid-reactive products of deoxyribose. Similarly, tyloxapol, cetyl alcohol, and the surfactant decreased hydroxylated products of salicylate in the same system. Rats were instilled intratracheally with saline, tyloxapol, tyloxapol plus cetyl alcohol, or artificial surfactant and immediately exposed to air or 100% oxygen. After 61 h of oxygen exposure, pleural fluid volume and wet-to-dry lung weight ratios were decreased in animals treated with surfactant and/or its components. There were also decrements in thiobarbituric acid-reactive products of lung tissue. In separate experiments, mean survival of saline-treated rats exposed to 100% oxygen was 67.3 +/- 8.1 h and > 96 h for rats given the surfactant or its components. We conclude that tyloxapol, cetyl alcohol, and Exosurf can function as antioxidants in vitro and their in vivo instillation is associated with reduction in measures of hyperoxic injury, oxidized tissue products, and mortality.

Abstract:

Two-step for wood esterification with oxalic acid and cetyl alcohol is developed in this study. The esterified wood powder was investigated by Fourier-transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD). The results show that ester groups substituted parts of the original alcoholic hydroxyl groups, and crystallization occurred during the modification. In addition, surface wettability, moisture adsorption and water absorption tests for wood specimen have showed that the modification improves the moisture and water resistance.

Abstract:

The catalytic hydrogenation of methyl palmitate to cetyl alcohol using Ni supported on activated natural zeolite catalysts (Ni/Zeolite) has been carried out. In this work, the effect of catalyst amounts and H2 flow rate on methyl palmitate conversion and yield of cetyl alcohol were studied. Catalytic hydrogenation was performed in stainless steel fixed bed reactor. The methyl palmitate (10 g) was loaded into the reactor vessel at 400 °C for 30 minutes. In order to study the effects of catalyst amount at constant H2 flow rate, the catalyst were varied i.e. 5, 10, and 15 g. To investigate the effects of H2 flow rate were varied from 20, 40, and 60 mL.min-1 at constant catalyst amount. The composition of the products was analyzed by GC and GC-MS. The results showed that methyl palmitate conversion increase with the increasing of catalyst amount. The highest methyl palmitate conversion (45.62 %) and yield of cetyl alcohol (36.44 %) were obtained for 15 g catalyst and 40 mL. min-1 H2 flow rate.

Abstract:

The purpose of the present study was to compare the in vitro release and to find out whether the bioavailability of a 75 mg indomethacin capsule (Microcid SR) was equivalent to optimized formulation (indomethacin-loaded cetyl alcohol microspheres). Indomethacin-loaded cetyl alcohol microspheres were prepared by meltable emulsified cooling-induced technique. Surface morphology of microspheres has been evaluated using scanning electron microscopy. A single dose, randomized, complete cross over study of IM microspheres was carried out on 10 healthy male and female Albino sheep’s under fasting conditions. The plasma was separated and the concentrations of the drug were determined by HPLC-UV method. Plasma indomethacin concentrations and other pharmacokinetic parameters obtained were statistically analyzed. The SEM images revealed the spherical shape of fat microspheres, and more than 98.0% of the isolated microspheres were in the size range 12–32 μm. DSC, FTIR spectroscopy and stability studies indicated that the drug after encapsulation with fat microspheres was stable and compatible. Both formulations were found to be bioequivalent as evidenced by in vivo studies. Based on this study, it can be concluded that cetyl alcohol microspheres and Microcid SR capsule are bioequivalent in terms of the rate and extent of absorption.

Abstract:

Aim: Paclitaxel (PTX) has no clinically available oral formulations. Cetyl alcohol is metabolized by alcohol dehydrogenase and aldehyde dehydrogenase that are overexpressed in cancer cells. So, PTX-encapsulated core–shell nanoparticle of cetyl alcohol (PaxSLN) could target the cancer cells through oral route. Materials & methods: PaxSLN was synthesized using microemulsion template. Efficiency of PaxSLN was evaluated by ALDEFLUOR™, multicellular tumor spheroid formation inhibition assays and CT26 colorectal carcinoma animal model. Pharmacokinetics and biodistribution studies were done in Sprague Dawley rats. Results: PTX was encapsulated at the core of approximately 78 nm PaxSLN. PaxSLN targeted aldehyde dehydrogenase overexpressing cells. Its oral bioavailability was approximately 95% and chemotherapeutic efficacy was better than Taxol® and nab-PTX. Conclusion: A novel oral nanoformulation of PTX was developed.

Abstract:

This study is focused on the modification of wood fiber by using a reactive diisocyanate (toluene diisocyanate, TDI) linker to couple wood fiber with cetyl alcohol and the investigation of its effects on mechanical properties of wood fiber–HDPE composites. The reaction of TDI with wood fiber and then cetyl alcohol resulted in the formation of new urethane bonds assessed by FTIR analysis. Therefore, TDI ended cetyl alcohol was used as a coupling agent in the preparation of wood fiber/ HDPE composite. The outcomes showed that the addition of such coupling agents resulted in greater reinforcement of composites, as indicated by the improvement in mechanical properties. Tensile strength of prepared composites increased by almost 64%, whereas 47% increase in flexural strength and 113% increase in impact properties was observed. However, the moisture absorption of the composites decreased by about 43%. All chemically treated composites showed lower moisture uptake than the untreated composites. This may be due to chemical treatment of wood fiber which reduces its hydrophilicity. These chemical treatments promote interfacial adhesion of fiber and HDPE matrix. Furthermore, scanning electron microscopy (SEM) revealed the improved morphology of the fractured surfaces of composites.

Full text

Abstract:

Water-repellency in sandy soils is determined by the amount of hydrophobic organic matter coating the sand particles and the specific surface area of the sands. The hydrophobic state can be simulated by coating hydrophilic sand with cetyl alcohol. Admixture of finely particulate materials with either naturally occurring water-repellent sands or the model cetyl alcohol-coated sand markedly reduced the water-repellency. Dispersible sodic clays were more effective than calcium saturated clays in reducing water-repellency, suggesting that the addition of dispersible, fine-grained illites and kaolinites couid play an important role in the rapid control of water-repellent soils in field situations.

Full text

Abstract:

The aim of the present study was preparation of hyaluronan (HA) targeted solid lipid nanoparticles (SLNs) of etoposide. SLNs were prepared by an emulsification-solvent evaporation method and physically coated with HA. Four variables, including the ratio of cetyl alcohol to cationic lipid, cationic lipid type (stearylamine (SA) or dodecylamine (DDA)), lipid to HA ratio, and organic to aqueous phase ratio, were studied in an irregular fraction factorial design. Four responses, including particle size, zeta potential, drug loading, and 24-hour release efficiency percent, were measured for each formulation and then the optimization was carried out. The percent of HA coated on the SLNs was calculated by CHN elemental analysis which was shown to be about 55.89%. The cationic lipid type and the ratio of cetyl alcohol to cationic lipid had the highest influence on particle size and zeta potential, respectively. The highest effects of the ratio of lipid to HA and the organic to aqueous phase ratio were on the drug loading efficiency of SLNs. The optimized formulation of SLNs was obtained by SA, the equal proportion of cetyl alcohol and cationic lipid, the ratio of 1.5 for lipid to HA, and 10% of organic phase to aqueous phase.

Abstract:

Effective atomic numbers (ZPIeff) and electron densities of eighteen alcohols such as wood alcohol, CH3OH; grain alcohol, C2H5OH; rubbing alcohol, C3H7OH; butanol, C4H9OH; amyl alcohol, C5H11OH; cetyl alcohol, C16H33OH; ethylene glycol, C2H4(OH)2; glycerin, C3H5(OH)3; PVA, C2H4O; erythritol, C4H6(OH)4; xylitol, C5H7(OH)5; sorbitol, C6H8(OH)6; volemitol, C7H9(OH)7; allyl alcohol, C3H5OH; geraniol, C10H17OH; propargyl alcohol, C3H3OH; inositol, C6H6(OH)6, and menthol, C10H19OH have been calculated in the photon energy region of 1 keV-100 GeV. The estimated values have been compared with experimental values wherever possible. The comparison of ZPIeff of the alcohols with water phantom and PMMA phantom indicate that the ethylene glycol, glycerin, and PVA are substitute for PMMA phantom and PVA is substitute of water phantom. ZPIeff of alcohols have also been compared with human organs and tissues. Ethylene glycol, glycerin and PVA, allyl alcohol, and wood alcohols are found tissue substitutes for most of human organs. Kerma which is the product of the energy fluence and mass energy-absorption coefficient, have been calculated in the energy region from 1 keV to 20 MeV for the alcohols. The results show the kerma is more or less independent of energy above 100 keV.

Abstract:

Artificial water-repellent sands were prepared in the laboratory from acid-washed sand and either cetyl alcohol or organics extracted from a natural water-repellent sand. Added clays (at 0.5% w/w) had no effect when gently mixed with a natural and the two artificial water-repellent sands. After a wetting and drying cycle, kaolinite reduced repellency to a low level in the natural sand and the artificial sand with extracted organics, but montmorillonite was not effective. Na+-saturated clays were generally more effective than Ca2+-saturated clays. In the cetyl alcohol sand, montmorillonite was more effective than kaolinite. Neither artificial sand was a perfect model of the natural system, although the extracted organic model was far superior. Kaolinite did not strongly adsorb hydrophobic molecules, but was effective because it was able to cover the hydrophobic sand surface. Application of kaolinite clay to a water-repellent sand appears promising.

Abstract:

The effect of ethoxylated oleyl-cetyl alcohol at a concentration of 1% on the growth and metabolism of A. tenuis Nees and P. verrucosum Dierckx was examined in this paper. The fungal growth was investigated by monitoring the diameter of colonies on solid media and dry weight biomass in liquid media. A. tenuis had better response to applied pollutant in solid medium, whereas P. verrucosum had better response in liquid medium. During exponential fungal growth in liquid media with and without pollutant (control), the following physico-chemical and biochemical parameters were carried out: pH, quantity of free and total organic acids, proteins, carbohydrates, proteolytic activity. The ethoxylated oleyl-cetyl alcohol had influence on decrease in pH value and increase in free organic acids of both fungi. Furthermore, it has influenced production in way that lower amount of total organic acids, proteins, glucose and fructose were gained in fermentation broth of P. verrucosum compared to A. tenuis. The proteolityc activity of fungi was partially (A. tenuis) or fully inhibited (P. verrucosum) by presence of pollutant in liquid medium. Based on the obtained results, these fungal species act as potential candidates for mycoremediation of alcohol ethoxylated contaminated environments and biotechnology.

Abstract:

The Ceteth family of ingredients are the polyethylene glycol (PEG) ethers of cetyl alcohol. They are manufactured by the ethoxylation of cetyl alcohol with the number of moles of ethylene oxide corresponding to the average polyethylene glycol chain length desired. Not all of the polymer chain lengths covered in this assessment are currently reported to be used, but all are listed as cosmetic ingredients and may have been used in the past and could be used in the future. Ceteths are surfactants used as emulsifying, cleansing, and solubilizing agents in cosmetic formulations. Limited safety test data are available on ingredients in the Ceteth family, all consistent with surfactant properties. In separate studies, 2.5% Ceteth-2 was irritating to abraded skin, but 3.0 % was not irritating to intact skin. Dose-dependent irritation was noted for Ceteth-2 and Ceteth-10 at concentrations ranging from 5% to 100%. Ceteth-20 was found to enhance transposition of a marker from phage λ to bacterial DNA. Toxicity data, including reproductive and developmental toxicity, carcinogenesis data, and clinical testing data, available from previous safety assessments on Polyethylene Glycol and Cetyl Alcohol, were summarized. Although PEGs were mild irritants/sensitizers, there was evidence of nephrotoxicity in burn patients exposed to PEGs, and no such effects were seen in animal studies on intact skin. This led to a recommendation that PEGs not be used on damaged skin. Irritant effects of Ceteths on abraded skin not seen with intact skin likewise suggested that cosmetic manufacturers should not use Ceteths in products that may be used on damaged skin. Although metabolites of ethylene glycol monalkyl ethers are reproductive and developmental toxins, it was considered unlikely that the relevant metabolites would be found in or produced from the use of Ceteths in cosmetic formulations. Of concern was the possible presence of 1,4-dioxane and ethylene oxide impurities. The importance of using the necessary purification procedures to remove these impurities was stressed. Inhalation of Cetyl Alcohol at 26 ppm for 6 hours caused mucosal irritation, but shorter exposures at a concentration of 9.6 mg/L caused no irritation. Based on this data and with particle size and cosmetic use concentrations, Ceteths were considered to be safe for aerosolized use. Based in part on the limited data available on Ceteths included in the report and on the previous reviews of the two components found in Ceteths, it was concluded that Ceteth-1, -2, -3, -4, -5, -6, -10, -12, -14, -15, -16, -20, -24, -25, -30, and -45 are safe in the present practices of use.

Abstract:

In this paper,the effect of surfactant to the infiltration and the change of saturated hydraulic conductivity was studied by GUELPH PERMEAMETER. We investigated effects on soil infiltration by three representative surfactants.The results show that the existing of sodium dodecyl benzene sulfonate (SDBS), cetyl trimethyl ammonium bromide bromide (CTAB) and polyxyethylene fatty alcohol (AEO9) would decrease soil saturated hydraulic conductivity.

Abstract:

A three-dimensional (3D) copper-based metal-organic frameworks or MOF-199 were successfully synthesized by utilizing palm oil based fatty alcohols that acted as renewable template. The synthesis of MOF-199 employed different length of straight chain of fatty alcohols namely octyl, decyl, lauryl, myristyl and cetyl alcohols derived from palm oil using similar method to those reported earlier with some modifications. The microstructure of MOF-199 exhibited single particles with fine octahedral morphology at various particle sizes in the range of ca. 15-60 μm. The nitrogen adsorption isotherms were conducted to estimate the surface area and pore volume of the materials and were at ca. 400 – 1100 m2g-1 and 0.17 – 0.43 mLg-1 respectively. The surface area and pore volume of the materials decreased with longer straight chain fatty alcohol possibility due to mobility of the long carbon chain.

Abstract:

A sustained-release non-effervescent floating matrix tablet was prepared using a simple and efficient direct compression of spray-dried granules containing metformin hydrochloride and cetyl alcohol with hydroxypropyl methylcellulose K15M (HPMC K15M). The design of experiments was employed to explore the optimal composition of the tablet. The similarity factor was employed to evaluate the equivalence in dissolution profiles between the test tablets and Glucophage XR as a reference. Bootstrap analysis was used to eliminate the formulations for which the dissolution profile was potentially inequivalent to that of the reference. The optimized tablet consisting of 150 mg of cetyl alcohol and 17% HPMC K15M showed a dissolution profile comparable with that of the reference with a similarity factor of 52.41, exhibited a floating lag time of less than 3 s in buffer media, remained floating for 24 h, and reduced the tablet weight by about 20% compared to that of the reference. The current study sheds light on the potential use of non-effervescent gastro-retentive extended-release tablets for high-dose drugs using a simple and efficient direct compression method, and as a potential alternative treatment for Glucophage XR. This study also highlights the importance of a systematic approach to formulation optimization and the evaluation of the dissolution profile.

Abstract:

A novel water-based paint stripper was prepared for white, metallic ink and varnish coated on the tinplate steel surface. The effect of accelerator and surfactant on stripping efficiency was investigated with the types and dosage of the accelerator and surfactant, the stripping temperature and stirring up condition. The highest stripping efficiency was achieved with the stripper composited by (mass fraction) 35% benzyl alcohol, 6% propanediol carbonate, 10% formic acid, 2% cetyl tri-methyl ammonium bromide (CTMAB) and 47% distilled water, respectively. This paint stripper had low volatility, and was not easy to burn. Scanning electron microscopy (SEM) test indicated that the paint stripper had little corrosive effect on tinplates.
