:

Diisooctyl phthalate

Description:
Diisooctyl phthalate (DIOP), with the CAS number 27554-26-3, is an organic compound belonging to the phthalate family, primarily used as a plasticizer in various applications. It is characterized by its high molecular weight and low volatility, which contribute to its effectiveness in enhancing the flexibility and durability of polymers, particularly polyvinyl chloride (PVC). DIOP is a colorless to pale yellow liquid with a mild odor and is insoluble in water but soluble in organic solvents. Its chemical structure features two octyl groups attached to the phthalate backbone, which imparts desirable properties such as low-temperature flexibility and resistance to extraction by oils and solvents. DIOP is often favored in applications requiring low toxicity and is used in products like adhesives, sealants, and coatings. However, like other phthalates, it has raised environmental and health concerns, leading to regulatory scrutiny regarding its use in consumer products. Overall, DIOP serves as a versatile additive in the plastics industry while being subject to ongoing research regarding its safety profile.
