OBJECTIVES Bisphenol A diglycidyl ether (BADGE) is a liquid compound obtained by condensation of two molecules of epichlorohydrin with one molecule of bisphenol A. General and reproductive toxicity with BADGE has been reported higher than 1000 mg/kg/day. This study was performed to show the effects of acute exposure to BADGE below 1000 mg/kg/day on the testis in adult male rats. METHODS BADGE...

A bio-oil-based epoxy (BOE) resin was synthesized using phenolic compounds from beechwood pyrolysis oil. These were separated crude oil by coupling two methods: fractional condensation and water extraction. The chemical structure of the BOE characterized NMR FTIR analyses. used as a curing agent bio-oil glyoxal novolac (BOG) to gradually replace bisphenol diglycidyl ether (DGEBA). thermal prope...

Soy-based adhesives inherently possess low water resistance and brittleness, which limit their application on plywood fabrication. This investigation involves using a long chain cross-linker, neopentyl glycol diglycidyl ether (NGDE), to produce an intrinsic toughening effect to reduce the brittleness and improve the water resistance of a soybean meal–based adhesive. The solids content, viscosit...

BACKGROUND Cosmetic procedures are growing ever more common, and the use of soft tissue fillers is increasing. Practicing physicians need to be aware of the biological behavior of these products in tissue to enable them to respond to any safety concerns that their patients raise. OBJECTIVES To provide an overview of the metabolism of 1,4-butanediol diglycidyl ether (BDDE)-crosslinked hyaluron...

The influence of epoxy active diluents, 1,4-butanediol diglycidyl ether (BD) and furfuryl glycidyl (FUR), in the mixtures with benzoxazine monomer based on bisphenol A, formaldehyde m-toluidine (BA-mt), properties a matrix was disclosed this work. Resins were modified to achieve good tackiness at room temperature reduced viscosity. mono- difunctional modifiers process curing studied by way diff...
