Dioctyl Phthalate (DOP) 100% White A Dioctyl Phthalate CAS 117-81-7

Plasticizer: DOP is widely used as a plasticizer in PVC products such as cables, flooring, wall coverings, and automotive parts. It softens the PVC resin and makes it more flexible, which is essential for various applications.

Chemical Structure: Chemically, DOP is an ester of phthalic acid and 2-ethylhexanol. Its chemical formula is C24H38O4. It's a colorless or light yellow liquid with a mild odor.

Properties: DOP has good compatibility with PVC and other polymers. It provides excellent low-temperature flexibility, heat stability, and electrical insulation properties to the products. Additionally, it improves the processability of PVC during manufacturing.

Usage: DOP is used in various industries including construction, automotive, medical devices, toys, and packaging. It's particularly prevalent in flexible PVC applications where flexibility and durability are crucial.

Health Concerns: There have been some health concerns associated with DOP, particularly regarding its potential to leach out of products and into the environment or human body. Studies have linked it to potential adverse effects on reproductive health and development in animals. As a result, there has been increasing scrutiny and regulation of its use in certain applications, particularly in products intended for children.

Regulation: Due to its potential health risks, DOP has faced regulatory restrictions in some regions. For instance, the European Union has placed limits on its use in certain applications, especially those involving children's products.

Alternatives: In response to health and regulatory concerns, there has been a growing interest in alternative plasticizers such as diisononyl phthalate (DINP), dioctyl terephthalate (DOTP), and others, which are considered to have lower toxicity profiles.
