Phthalate Di-butyl phthalate - GreenFacts
Di-butyl phthalate. 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.
Reducing Disinfection Byproducts through Optimization - ASDWA
DBP formation is a function of temperature, water age, Cl 2 & NOM concentration, NOM composition, and pH Disinfectant Natural Organic Matter (TOC, UV 254 DBPs (TTHM, HAA5, NDMA, others) Process to Reduce DBPs through Optimization System is not in compliance with DBP Rule. Conduct DS influent hold study (duration = system ’s MRT).
Taylor-Dunn Hauling and Towing Guide
To calculate reduced towing capacity DBP, use this formula: Reduced DBP = DBP – Vl * (DBP/Vc) Vc = Vehicle Rated Capacity DBP = Normal Draw Bar Pull specification Vl = Vehicle Load (includes passengers and options). The weight that the vehicle can pull can be calculated based on the DBP.
Dibutyl Phthalate - an overview | ScienceDirect Topics
It has been used in insect repellents and as a solvent for perfume oil and resins. Dibutyl phthalate can be used as a plasticizer in nitrocellulose lacquers, elastomers, explosives, nail polish, and solid rocket propellants. Other uses include perfume fixative, textile lubricating agent, safety glass additive, printing inks, and adhesives.
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 , .
- 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.
- Do DBP additives affect physicochemical properties of MPs?
- However, the addition of DBP additives may alter the physicochemical properties of the MPs surface, including surface hydrophilicity, functional groups, electrical charge, and thermal stability; thereby affecting the interfacial behavior of MPs in the environment .
- 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 %.
- 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.
- 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.
