“…This is often the phthalate di-ester, di-2-ethylhexyl phthalate (DEHP) (Cadogan et al 1999;Wilson 1995;Ejlertsson et al 1997), but others such as di-2-ethylhexyl adipate (DEHA) are also commonly used (Tepper 1973;Startin et al 1987;Nerin et al 1992;Bohnert et al 1999;Lang and Stanhope 2001). A study in Germany in 2002 found average DEHP levels of 2.27 lg/l in surface waters and 0.70 mg/kg in sediments (Fromme et al 2002).…”

Effect of surfactants on plasticizer biodegradation by Bacillus subtilis ATCC 6633

The biodegradation of plasticizers has been previously shown to result in the accumulation of metabolites that are more toxic than the initial compound. The present work shows that the pattern of degradation of di-2-ethylhexyl adipate by Bacillus subtilis can be significantly altered by the presence of biosurfactants, such as surfactin, or synthetic surfactants, such as Pluronic L122. In particular, this work confirms that the monoester, mono-2-ethylhexyl adipate, is a metabolite in the breakdown of the plasticizer. This metabolite was proposed but not observed in earlier studies. Toxicity measurements showed it to be significantly more toxic than the plasticizer. Thus, the effect of the surfactants was to significantly increase the accumulation of one or both of the two most toxic metabolites; i.e., the monoester and 2-ethylhexanol. It was proposed that the most likely cause of the effect of the surfactants was the sequestering of these two metabolites into mixed micelles, resulting in their reduced availability for further degradation.

“…The lubricant treatment improved the friction properties and surface structuring had a great effect on the water contact angle. The common targets of modification of plastic surfaces were to develop new plasticizers and mixtures (Bohnert et al 1998, Puukilainen and Pakkanen 2005, Koponen et al 2007a, and to modify hydrophobic properties (Fresnais et al 2006, Li et al 2006, Puukilainen et al 2006, Koponen et al 2007b) and surface structures (Li et al 2006, Puukilainen et al 2006, Koponen et al 2007b. Surface structure was reported to affect the hydrophobic properties (Fresnais et al 2006, Li et al 2006, Koponen et al 2007b).…”

Each vinyl plastisol processor has different requirements. The features of the finished goods determine the specifications and physical properties that are critical in the manufacturing process. Processors may also have varying equipment limitations that require a specific working range of each plastisol property, such as viscosity, for acceptable processing. Although the benzoate esters have been utilized for many years by plastisol formulators and processors to their advantage, usage of these esters has been limited because of their tendency to yield high-viscosity plastisols. By utilizing a formulary approach, it is possible to fine-tune the properties of the plastisol, thus allowing greater latitude. Design of experiment (DOE) was employed to accomplish this objective. For this work, generic resilient-flooring formulations were selected as the model. The formulary approach was employed to adjust the formulation and processing parameters, thereby allowing plastisol formulators and processors to develop cost-efficient formulations. J. VINYL ADDIT.
