[Extraction of di-2-ethylhexylphthalate from PVC used in synthetic leather].
The extraction of the plasticizer di (2-ethylhexyl) phthalate (DOP) from PVC plastics was evaluated with a solvent mixture similar to that found in shoemaker's glues, sunflower oil, and in an aqueous emulsion resembling crude human sweat as far as the solubility of many organic compounds, including plasticizers is concerned. The aim was to evaluated the availability of plasticizers to be absorbed at skin level in PVC plastics, used as synthetic leather. The results indicated that the extraction of DOP is of practical importance only in the presence of a solvent mixture. Therefore the direct skin contact with PCV plastics containing DOP is much less significant as regards plasticizer absorption.
