Plasticizer and Stabilizer


Plasticizers in Context

Advocates of healthy building materials have long targeted products made with polyvinyl chloride (PVC, also sometimes referred to as “vinyl”)a for elimination. Much of the concern arises from the way all PVC begins and ends its lifecycle. Its manufacture requires chlorine, and when PVC is in a fire or heated to high temperatures in manufacturing processes, trouble ensues, such as the release of highly toxic dioxins, vinyl chloride monomer, and hydrogen chloride.b Also exacerbating PVC’s toxicity throughout its lifecycle are toxic additives such as heavy metal stabilizers, which are required to keep PVC from breaking down during manufacture and use, and phthalate plasticizers, which are required to make PVC flexible. Heavy metals used in stabilizers include lead, a potent developmental toxicant; cadmium, a potent neurotoxin and carcinogen; and organotins, some of which are reproductive and developmental toxicants. Many phthalate plasticizers are known endocrine disrupting chemicalsc - chemicals that disrupt hormone cell signal pathways – and have been known to have toxic effects on reproduction and development. Additionally, some phthalates are known carcinogens. These additives are not tightly bound to the PVC molecules and have been known to migrate from PVC products. d U.S. and European manufacturers have replaced lead and cadmium stabilizers with calcium-zinc, barium-zinc, and organotin stabilizers in most applications. 


Comparing the Toxicity of Alternatives 

To ensure that regrettable substitutions (trading one bad chemical for another bad chemical g ) aren’t made, HBN took a deeper look at these alternative plasticizers. While multiple alternatives have been identified via various alternative assessments, HBN narrowed its review to those plasticizer alternatives that HBN has identified as in use in commercially-available phthalate-free PVC building products. Through this lens, HBN identified six alternative plasticizer types in commercial use: ? Di-(2-ethylhexyl) terephthalate (DEHT a.k.a DOTP) ? Diisononyl cyclohexane-1,2-dicarboxylate (DINCH) ? Dibenzoates [commonly Dipropylene glycol dibenzoate (DGD) or a blend of DGD, Diethylene glycol dibenzoate (DEGD), and Triethylene glycol dibenzoate (TGD)] ? Acetylated monoglycerides of fully hydrogenated castor oil (COMGHA) ? Isosorbide diesters ? Ecolibrium [a proprietary vegetable oil based blend]
