The Dibutyl phthalate applied in new and old times

Dibutyl phthalate is widely used in plastic (such as PVC pipe and carpet backing), paints, varnishes and paints, pharmaceutical products (such as blood transfusion and dental materials), safety glass of the automobile, food packaging, cosmetics (such as the production of nail polish and perfume oil), textiles (as a lubricant and repellent impregnated in the clothing), and paper coating. Although used as repellents, dibutyl phthalate were not considered to be adjacent benzene two methyl formate as effective as of two. Because it used in the world, has a high potential in the workplace, through the direct source of human exposure and family environment. In addition, in the water, air and food due to the existence of dibutyl phthalate(Dioctyl Phthalate)in the environment and the leaching products universal many indirect sources of pollution. For long-term human exposure to environmental chemicals such as pesticides, plasticizers, especially in the womb and newborn potential, the extra attention.

Dibutyl phthalate is known by the plastic, to penetrate the blood and milk and other foods, which entered the body (guess et al., 1967). According to estimates, 150 mg of dibutyl phthalate will become 1 kg of cheese moved 15%, fat content (Overcash, 1982). Dibutyl phthalate were identified in plasma tissue of patients with hemodialysis or blood transfusion (Green et al., 1981). Production of dibutyl phthalate, in American in 1977 and 1982 is 7720000 kg (RTECS, 1994).
PVC is a thermoplastic resin, which in versatility of processing and application surpasses all other thermoplastic materials. This unique polymer is one of the oldest established plastics. Today, PVC finds applications in insulation of cables, in pipes and hoses, agricultural products, windows and profiles, flooring tiles used in the building industry, blister packaging, films and sheets, foamed leather cloth, curtains, tarpaulins, and also for medical use - for IV, blood bags, etc. The universality of its service properties is such that new areas of application are being continuously developed.
