To examine potential contamination of specimens, we also compared the distributions of free phenol and paraben concentrations as a percentage of the total concentration for the five compounds with sufficient detection: BPA, butyl paraben, methyl paraben, propyl
paraben, and benzophenone-3.
Aqueous emulsion of propyl
isothiocyanate at concentrations: 0, 0.
In these same studies we discovered the metabolic route of formation of normal propyl
alcohol, the fusel oil component that does not correspond directly to any amino acid.
Of these compounds only propyl
gallate and TBHQ were able to inhibit lipid oxidation in cooked ground beef.
The broth had been supplemented with either L-ascorbic acid or propyl
gallate alone or in combination with lactic acid.
15) the sonication effects are large for ethyl and propyl
acetates, indicating a considerable interaction of esters with the solvent system.

The former EC Scientific Committee for Food (SCF) evaluated the parabens in 1994 and allocated a temporary group ADI of 0-10 mg/kg bw (milligrams/kilogramme body weight), for the sum of methyl, ethyl and propyl
p-hydroxybenzoic acid esters and their sodium salts.
Kingsport, TN-based Eastman Chemical Company has introduced Methyl Propyl
Ketone, its non-HAP solvent for pre-saturated industrial wipes.
Peak concentrations of propyl
nitrate and butyl nitrate in south-central Kansas were 51 and 68 parts per trillion, respectively.
gallate (PG) complexes have been successfully used for adsorptive stripping of other metals such as chromium and uranium (7).
The final topping of this unhealthy concoction is lots of preservatives, such as BHA, BHT, Ethoxyquin, propyl
gallate, benzoate of soda plus artificial colorings and flavorings.
