Dibutyl Phthalate (DBP), scientifically known as phthalic acid di-n-butyl ester, is a compound with a rich chemical profile that has led to its extensive use across various industries. At NINGBO INNO PHARMCHEM CO.,LTD., we focus on delivering comprehensive information about the chemicals we supply, and understanding the intrinsic properties of DBP is fundamental to appreciating its applications.

Chemically, DBP (CAS No. 84-74-2) is an organic compound belonging to the phthalate ester family. It is characterized as a diester formed from phthalic acid and n-butanol. Its molecular formula is C16H22O4, and it has a molar mass of approximately 278.348 g/mol. Physically, DBP is a colorless, oily liquid with a very faint, sometimes described as aromatic, odor. It has a high boiling point, typically around 340 °C, and a melting point of approximately -35 °C. Its solubility in water is limited, but it is readily soluble in most organic solvents, including alcohols, ethers, and benzene, which contributes to its utility in various formulations.

The dibutyl phthalate properties make it an excellent plasticizer, a key role it plays in enhancing the flexibility, durability, and processability of polymers, most notably PVC. The addition of DBP reduces the glass transition temperature of PVC, making it less brittle and easier to shape into various forms. This has led to its widespread use in applications such as flexible films, cables, flooring, and medical devices. The dibutyl phthalate applications in PVC are extensive and have been critical for the development of many modern plastic products.

Beyond its primary function as a plasticizer, DBP has found application in a broader range of industries. Its properties as a solvent and fixative have led to its use in printing inks, adhesives, lacquers, and even in the fragrance industry. Historically, it was also incorporated into some cosmetic products and insecticides. The dibutyl phthalate CAS 84-74-2 uses highlight its versatility as a chemical intermediate and additive across different manufacturing processes.

While DBP offers significant industrial advantages, it's important to note the ongoing discussions and regulations surrounding its use due to health and environmental considerations. NINGBO INNO PHARMCHEM CO.,LTD. is committed to providing clients with accurate dibutyl phthalate safety data and information on regulatory compliance.
