a
LMW, low-molecular weight phthalates, are added to personal care product to preserve scent.
b
HMW, high-molecular weight phthalates are used as plasticizers of polyvinyl chloride (PVC) to increase flexibility, and can be found in a variety of settings ranging from flooring, clear food wrap and intravenous tubing (Schettler, 2006).
