1 June 2009 Background document for dibutyl phthalate (DBP)
DBP is then further used for formulation and processing by major users at 50-100 sites in the EU; in addition, an unknown number of minor users exists (COWI, IOM & Entec, 2009). The different applications and relatively high amounts of DBP used may indicate that a large number of companies (assumed to be more than 1 000) are
Dibutyl phthalate
Dibutyl phthalate ( DBP) is an organic compound which is commonly used as a plasticizer because of its low toxicity and wide liquid range. With the chemical formula C 6 H 4 (CO 2 C 4 H 9) 2, it is a colorless oil, although commercial samples are often yellow. [3] Production and use [ edit]
Dibutyl Phthalate - an overview | ScienceDirect Topics
Dibutyl phthalate has multiple uses in a variety of materials. Primary uses for dibutyl phthalate are to soften and increase plastic flexibility, for example, in shower curtains, raincoats, food wraps, and car interiors to name a few. It has been used in insect repellents and as a solvent for perfume oil and resins.
Good Stability Dibutyl Phthalate What Is It Used
DBP is the most commonly used plasticizer of PVC, which can make products have good softness. DBP is an excellent plasticizer for nitrocellulose, with strong gelation ability.Stability, flexural resistance, adhesion and water resistance are better than other plasticizers.

- What is dibutyl phthalate (DBP)?
- Dibutyl phthalate (DBP) is widely used as a plasticizer (in the range of 10–35 %) in polyvinyl chloride (PVC) plastic products, including cosmetics, plastic food packaging, medical devices, building materials, and electronic products , .
- Are MPs a long-term source of DBP contaminants?
- MPs may be a long-term source of DBP contaminants in both freshwater and seawater. Dibutyl phthalate (DBP) as a plasticizer has been widely used in the processing of plastic products. Nevertheless, these DBP additives have the potential to be released into the environment throughout the entire life cycle of plastic products.
- What controls the leaching of DBP from MPs?
- The leaching of DBP from MPs is primarily controlled by intraparticle diffusion. MPs may be a long-term source of DBP contaminants in both freshwater and seawater. Dibutyl phthalate (DBP) as a plasticizer has been widely used in the processing of plastic products.
- How does additive DBP affect the release of DBP?
- The release of DBP into the environment increases proportionally with higher concentrations of additive DBP in MPs, particularly when it exceeds 15 %. The surface of MPs undergoes accelerated oxidation and increased hydrophilicity under UV radiation, thereby facilitating the leaching of DBP.
- Why do MPs release a lesser amount of DBP in seawater?
- Furthermore, certain metallic elements present in seawater, such as Na +, Ca 2+, and Fe 2+, have the ability to form complexes with DBP, thereby impeding its migration , , . This phenomenon elucidates why MPs release a lesser amount of DBP in seawater compared to freshwater.
- How does plasticizer content affect the release of DBP?
- The results show that the plasticizer content, UV irradiation, and hydrochemical conditions have a great influence on the leaching of DBP from the MPs. The release of DBP into the environment increases proportionally with higher concentrations of additive DBP in MPs, particularly when it exceeds 15 %.
