Understanding CAS No. 139-07-1 The Substance, Its Uses, and Safety

Chemical substances are often identified by unique numerical identifiers known as CAS Registry Numbers. One such substance is identified by the CAS No. 139-07-1, which corresponds to an organic compound known as Bis(2-ethylhexyl) phthalate, commonly referred to as DEHP. This article aims to provide a comprehensive overview of DEHP, including its properties, common applications, safety concerns, and regulatory status.

Properties of DEHP

DEHP is a phthalate ester, which is a type of chemical compound derived from phthalic acid. It is often characterized as a colorless to yellowish oily liquid with a slight aromatic odor. DEHP is known for its excellent solvency properties, chemical stability, and ability to enhance the flexibility and durability of polymer materials, particularly polyvinyl chloride (PVC). Its molecular formula is C24H38O4, and it has a molecular weight of 390.57 g/mol. DEHP is not only soluble in organic solvents but is also resistant to heat, making it an ideal candidate for various industrial applications.

Common Applications

DEHP is predominantly used as a plasticizer, a substance added to materials to increase their flexibility, transparency, durability, and longevity. It is extensively used in the production of PVC products, which are commonplace in the construction, automotive, medical, and consumer goods sectors. Some notable applications of DEHP include

1. Medical Devices DEHP is commonly used in medical PVC products, including intravenous (IV) bags and tubes, due to its ability to enhance the performance and handling of plastic materials. However, its usage has raised concerns regarding potential health effects.

2. Building and Construction In construction, DEHP is utilized in flooring, wall coverings, and electrical cables, providing improved flexibility and resilience.

3. Automotive Industry It is employed in the manufacture of automotive interiors, including dashboards, seat covers, and insulation materials.

4. Consumer Goods DEHP can also be found in items such as toys, cosmetics, and household products, where flexibility and durability are essential.

Safety Concerns and Regulatory Status

Despite its beneficial properties, DEHP has been the subject of growing concern regarding its environmental and health impacts. Research suggests that DEHP may pose reproductive and developmental risks, particularly when individuals are exposed to high levels over prolonged periods. Studies have indicated possible links between DEHP exposure and endocrine disruption, leading to potential reproductive issues and developmental problems in children.

Due to these concerns, many health and environmental regulatory agencies have imposed restrictions and guidelines on the use of DEHP. In the European Union, DEHP has been classified as a substance of very high concern (SVHC) under the REACH regulation, which aims to protect human health and the environment from the risks of chemicals. In the United States, the Environmental Protection Agency (EPA) and the Food and Drug Administration (FDA) have also been monitoring the usage of DEHP, particularly in medical devices and children's products.

Conclusion

CAS No. 139-07-1 identifies DEHP, a versatile plasticizer widely used across various sectors, from medical devices to consumer products. While it plays an essential role in enhancing the properties of plastics, its potential health risks cannot be overlooked. As regulatory scrutiny increases, industries are urged to explore safer alternatives for plasticizers in response to health and environmental concerns. Continuous research and monitoring are crucial to ensure that the benefits of DEHP utilization do not come at the expense of public health or environmental integrity. By prioritizing safety and sustainability, industries can adapt to evolving regulations while continuing to meet consumer needs effectively.
