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]
2. How is DBP used? - GreenFacts
The largest usage of DBP in general is as a plasticizers in resins and polymers such as polyvinyl chloride. Plasticizers are materials incorporated into a plastic in order to increase its workability and distendability.

Another explanation is that low DBP is really a marker for widened pulse pressure, which is an indicator of increased arterial stiffness and atherosclerosis. Finally, some have suggested that...
Phthalate Di-butyl phthalate - GreenFacts
Context - Dibutyl Phthalate (DBP) is used in a wide range of products for everyday use such as plastics, paints, inks and cosmetics. Its widespread use has raised some concerns on the safety of this compound. Is DBP posing a risk to health or the environment? The same information on
What Causes Low Diastolic Blood Pressure? - MedicineNet
10 Signs and Symptoms. Treatment. A diastolic blood pressure (DBP) of somewhere between 60 and 90 mm Hg is good in older people. Causes of low DBP include bed rest, dehydration, loss of water, alcohol use, hormone deficiencies, allergic reactions, nutritional deficiencies, and prolonged standing leading to blood pooling in the legs.
- What is dibutyl phthalate (DBP)?
- N verify (what is YN ?
- ) 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 impurities often render commercial samples yellow.
- What is DBP used for?
- DBP is an important plasticizer that enhances the utility of some major engineering plastics, such as PVC. Such modified PVC is widely used in plumbing for carrying sewage and other corrosive materials. Hydrolysis of DBP leads to phthalic acid and 1-butanol. Monobutyl phthalate (MBP) is its major metabolite.
- 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.
- 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.
- 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.
- Is DBP leaching a slow process?
- The release rate (kid) of the first stage (0.0029–0.3674 mg g -1 h -0.5) is greater than that of the second stage (0.0004–0.0843 mg g -1 h -0.5), which implies a gradual transition of DBP leaching process by the MPs from the surface to the interior into a slow process.
