Dermal Absorption of Phthalate Diesters in the Rat. ELSISI, A. E., CARTER, D. E., AND SIPES, I. G. (1989). Fundam Appl. Toxicol. 12, 70-77. This study examined the extent of dermal absorption of a series of phthalate diesters in the rat. Those tested were dimethyl, diethyl, dibutyl, diisobutyl, dihexyl, di(2-ethylhexyl), diisodecyl, and benzyl butyl phthalate. Hair from a skin area (1.3cm in di...
The effects of mono- and dibutyl phthalate and mono- and di(2-ethylhexyl) phthalate on energy-dependent K+ uptake, respiration rates, and succinate cytochrome c reductase activities of isolated rat liver mitochondria were evaluated. The energy-coupling processes, active K+ transport and oxidative phosphorylation, were affected most by di-n-butyl phthalate and mono(2-ethylhexyl) phthalate. Mono-...
Experimental vapor pressures, vaporization, fusion and sublimation enthalpies of a number of dialkyl benzenedicarboxylates have been examined by correlation gas chromatography (CGC) experiments in order to identify a series of experimental measurements that appear to be internally self-consistent. The compounds studied in this regard include dimethyl phthalate dimethyl terephthalate, dimethyl i...
Analysis of the natural abundance C content of dibutyl phthalate (DBP) from two edible brown algae, Undaria pinnatifida and Laminaria japonica, and a green alga, Ulva sp., revealed that the DBP was naturally produced. The natural abundance C content of di-(2-ethylhexyl) phthalate (DEHP) obtained from the same algae was about 50-80% of the standard sample and the C content of the petrochemical (...
The phthalate esters contents of children toys were analyzed using High Performance Liquid Chromatography (HPLC). Understanding the distribution of ubiquitous phthalate esters in plastic products were necessary because of their subtle toxicity to humans. The phthalate esters were obtained using liquid-liquid extraction procedure, after which the extracts were cleaned up using solid phase clean ...
Data for the following three liquids are used for the analysis in Figs. 1-4 of the paper: tetramethyltetrahpenyl-trisiloxane (DC704), 5-polyphenyl-4-ether (5PPE), tripropylene glycol (TPG). In this supplementary we also include data for triphenyl phosphite (TPP), dibutyl phthalate (DBP), diethyl phthalate (DEP), and 2,3-epoxy propyl-phenyl-ether (2,3-epoxy). A summary of relevant information ab...
dibutyl phthalate (dbp) is a phthalic acid ester and is widely used in polymeric products to make them more flexible. dbp is found in almost every plastic material and is believed to be persistent in the environment. various analytical methods have been used to measure dbp in different matrices. considering the ubiquitous nature of dbp, the most important challenge in dbp analyses is the contam...
Plasticizers in 101 samples of polyvinyl chloride (PVC) toys on the Japanese market were surveyed. No phthalates were detected in designated toys, though bis(2-ethylhexyl)phthalate, diisononyl phthalate, diisobutyl phthalate, dibutyl phthalate, diisodecyl phthalate and benzyl butyl phthalate were detected in more than half of other toys. 2,2,4-Tributyl-1,3-pentanediol diisobutylate, o-acetyl tr...
