The industry under consideration uses chiefly the phthalate plasticizers: predominantly dibutyl phthalate (DBP) and higher alkyl phthalates (DAP-789); periodically dioctyl phthalate (DOP), diisooctyl phthalate (DIOP), and benzyl butyl phthalate (BBP). Some formulations contain small amounts of one of the sebacates (dibutyl sebacate, DBS, or dioctyl sebacate, DOS) or adipates (dibutyl adipate, D...

this research was conducted to investigate the physico-mechanical characteris-tics of the ethylcellulose-based coating membranes plasticized with different weight percents of dibutyl sebacate. in this experiment, free thin polymer sheetings of the sample formulations, by incorporating incremental weight percents of the plasticizer, were prepared employing a revised casting method of delayed sol...

Purpose: To to develop and evaluate matrix-type ondansetron hydrochloride (OS) transdermal patch for the treatment of chemotherapy-induced nausea and vomiting. Methods: Transdermal patches were prepared by solvent casting method using ethyl cellulose and polyvinyl pyrrolidone as matrix materials, and dibutyl phthalate and dibutyl sebacate as plasticizers. The formulations were evaluated for pat...

The ionophore 1,4,7,10,13-penta(n-octyl)-1,4,7,10,13-pentaazacyclopentadecane (L) was used for the development of miniaturised perchlorate-selective electrodes in thickfilm technology. Different PVC membranes containing L and the plasticizers o-nitrophenyl octyl ether (NPOE), dibutyl phthalate (DBP), bis(2-ethylhexyl)sebacate (DOS) and dibutyl sebacate (DBS) were prepared and placed on a graphi...

Otto Fuel II is a mixture of three component chemicals, propylene glycol dinitrate, 2-nitrodiphenylamine, and dibutyl sebacate. Otto Fuel II enters the environment as these three components, which partition to the different environmental media according to their individual chemical and physical properties. Otto Fuel II is primarily released to water in waste streams from Navy facilities that pr...

Acetyl tributyl citrate (ATBC) and dibutyl sebacate (DBS) plasticizers are components of polyvinylidene chloride. These compounds can pass from the polyvinylidene chloride packing films to the enclosed food (Baba et al. 1988). Therefore, there may be a potential hazard to health. Toxicity of these compounds in laboratory animals is well known (Mallette and Haam 1952; Smith 1953; Finkelstein and...

This paper presents the improvements for the performance of a micro-electrohydrodynamic (EHD) pump and the fundamental model theory based on unipolar charge conduction. The EHD pump was fabricated with thin stainless wires which are the diameter of 0.3mm. An electrode pair consisted of one emitter electrode and two collector electrodes. The distance between the emitter and the collector electro...

Thin films made of a polymer (cellulose triacetate, CTA) and plasticizer have been studied as novel sorptive phases for chlorpyrifos, triclosan tonalide. The preparation is reproducible only requires the to be added into an organic dispersion containing CTA. evaporation solvent leaves easy manipulate continuous homogeneous thin film, which has investigated in terms both composition extraction e...
