In recent years plasticizer has higher social exposure rate special on food packages, on the surface, people can find relative foods manufacturers illegally added O-benzene plasticizers, but through deeply analyze, is resulted by backward on technical analysis and service manual in China.
EU introduced interim regulation on limitation of DOP and DOTP in children toys in 1999, CPSC of USA also declared that phthalic acid esters in children products must not exceed 0.1% and forbidden O-benzene plasticizers increased to 8 items from 3 items including DINP which is thought as close to environment protection plasticizer in China. Although we issued relative limitations, but the gap is large with developed countries on forbidden items and content. Plastic products and toy manufacturers have still used O-benzene plasticizers even some medical appliance factories used DOP as plasticizer only for it has good plasticizing effect and lower cost. That means government has weak supervision and inspection on application of plasticizer.
In 2014 Rhone-Poulenc company of France closed their 80,000 kg DOP line, that marked all O-benzene plasticizers had been weeded out in Europe. But in Chinese market O-benzene series plasticizers is still dominant on capacity and output. Recently eco-friendly plasticizers such as DOTP are rising but face to more resistance on sales and development. For example, citrate series plasticizers are welcomed abroad but a few of factories to produce ATBC, TBC in China, the output is less than 2% in plasticizer industry. The development disadvantageous is because of higher price, raw materials and plasticizing effect not better than O-benzene plasticizers. Other plasticizers such as DOTP, DINCH, D-801 also faced to consumption habit of users, promotion speed was far beyond abroad.
