Application

  • Influence on Poly(lactic acid) Fiber Production: Research highlights how low-molecular-weight esters like Bis(2-ethylhexyl) adipate can enhance the melt spinning and structural properties of poly(lactic acid) fibers, suggesting potential advancements in textile manufacturing technologies (Gzyra-Jagieła et al., 2024).
  • Environmental Analysis of Atmospheric Particles: A new method using GC Orbitrap-MS has been developed for the simultaneous analysis of phthalate esters and Bis(2-ethylhexyl) adipate, it is commonly used as plasticisers in consumer and industrial products (Argamino et al., 2024).
  • Study on Reproductive Endocrine Disruption: Examination of the effects of Bis(2-ethylhexyl) adipate, among other plasticizers, on gene expression related to the reproductive endocrine system in Japanese medaka fish, contributing to our understanding of environmental endocrine disruptors (Horie and Uaciquete, 2023).
  • Health Risk Assessments in Urban Environments: Bis(2-ethylhexyl) adipate was included in a comprehensive study assessing health risks associated with organic compounds in atmospheric fine particles, aimed at improving public health safety measures in populated regions (Gao et al., 2024).
  • Exposure from Plastic Water Bottles: The presence and implications of micro(nano)plastics, including polymers plasticized with Bis(2-ethylhexyl) adipate, in single-use plastic bottles were analyzed, indicating potential human exposure risks from everyday plastic use (Vega-Herrera et al., 2023).
