Migration of phthalates was investigated into water packed in PET bottles under various storage conditions to assess the risk assessment to children. It appeared that increases in the temperature and duration of storage affected phthalate migration, but the level of DEHP in bottled water was always ...
PET bottle migrated higher than the 1.5-liter PET bottle due to its larger surface area for water contact and higher surface-to-volume ratio; however, it was found that production contamination, not migration, was the cause of the higher Di methyl phthalates concentrations in the PC bottles. ...
For free acids a gradient of 9–45% methanol in 0.1% (v/v) formic acid/water was applied. Metabolites were identified by their retention times and ultraviolet/Vis spectra compared with standards. Enzyme assays Succinyl-CoA-dependent product formation was investigated at 30 °C by adding varying...

Dietary exposure to BPA is a major source since BPA can easily leach from consumer products made of polycarbonate plastics, including food containers and water bottles, into food or beverage, particularly at high temperature (EFSA 2006; Chapin et al. 2008; NTP-CERHR 2008). As such, it is ...
Water was filtered by Milli-Q and double distilled. All organic solvents used were of analytical grade and redistilled with glass system. All the laboratory glass apparatus were soaked in K2Cr2O7 sulfuric acid solution for at least 12 h and rinsed with organic-free reagent water thoroughly and ...
Better-Bottle PET carboys, often referred to as Better-Bottle fermenters or Better-Bottle bottles, are BPA-free, DEHP-free, plasticizer-free, light weight, and safe. A Better-Bottle carboy will not shatter the way glass carboys do. In fact, all Better-Bottle fermentation equipment is extrem...
Since bisphenol A (BPA) is widely used in the manufacture of polycarbonate plastics, epoxy resins and thermal paper, it is found in many products such as plastic bags, water bottles, toothpastes, electronic equipment, paper and toys [22]. In addition to BPA being one of the endocrine disrup...
While water bottles may tout BPA-free labels and personal care products declare phthalates not among their ingredients, these assurances may not be enough. According to a study published February 27 in the Nature'sJournal of Exposure Science and Environmental Epidemiology, people may be exposed to ...
For example, a good balance between pressure drop and hydrohead (water barrier) of these systems is desired. Thus, the object of the present invention is to provide a polymer composition based on phthalate free ZN-catalyst which is suitable for the preparation of melt blown fibers and webs ...
