A potentially general approach to aliphatic ester-derived PVC
The safety of flexible polyvinyl chloride (PVC) materials is now being questioned, partially due to allegations that di-(2-ethylhexyl) phthalate (DEHP), the dominant PVC plasticizer, is an endocrine disruptor and a probable carcinogen. As sustainable alternatives, aliphatic ester-derived plasticizers feature
Plasticizers - Chemical Economics Handbook (CEH) | S&P Global
Flexible PVC (and thus plasticizers) is found in the following applications: construction (flooring, wall coverings), electrical (wire and cable jacketing), consumer goods (toys, footwear, etc.), packaging, transportation (inside and outside of vehicles), furnishings, and medical uses (tubing, blood bags).

DEHT is a suitable plasticizer option for phthalate-free
Abstract. Background and objectives: Due to increasing concerns about possible endocrine-disrupting properties, the use of the plasticizer di (2-ethylhexyl) phthalate (DEHP) will be banned in future blood storage. Di (2-ethylhexyl) terephthalate (DEHT) provides sufficient red blood cell (RBC) quality during conventional blood bank storage.
Non-phthalate plasticizer DEHT preserves adequate blood
DEHP is favourable for storage of red blood cells (RBC). Historically, removal of DEHP from blood bags has been linked to unacceptable haemolysis levels. Oncoming regulatory restrictions for DEHP due to toxicity concerns increase the urgency to replace DEHP without compromising RBC quality.
