A study of an eco-friendly solvent helping to make PVC plastic more flexible reveals the molecular-level interaction of hydrogen bonds between the two ingredients. What gives plastic objects their flexibility and reduces their brittleness is the concentration of plasticizer. For example, a chemical solvent of the phthalate family called DOP is often used. The trouble is there are concerns that phthalates present health risks. So there is a demand for more alternatives. Now, scientists have examined the effect of using DEHHP, a new eco-friendly plasticizer, used in combination with PVC.
