At NINGBO INNO PHARMCHEM CO.,LTD., we believe in providing comprehensive information about the chemicals we supply. Dioctyl Phthalate (DOP), a prominent plasticizer, possesses a distinct set of chemical properties that dictate its performance and applications. Understanding these properties, along with the associated safety and regulatory considerations, is crucial for responsible use. This article delves into the chemical characteristics of DOP and examines the current safety landscape.

Dioctyl Phthalate, with the chemical formula C24H38O4, is an ester of phthalic acid. It typically presents as a colorless to light yellow, oily liquid with a mild, characteristic odor. Key physical properties that contribute to its widespread use include its relatively low volatility, owing to a high boiling point of approximately 384°C (723°F). This low volatility ensures that DOP remains integrated within the polymer matrix, minimizing loss and degradation over time. Its density, around 0.98–0.99 g/cm³ at 20°C, facilitates easy mixing and blending with various polymers and resins, which is essential for achieving consistent material properties. The benefits of using DOP in plastics are directly linked to these intrinsic chemical properties.

As a plasticizer, DOP's primary role is to enhance the flexibility and workability of polymers like PVC. It achieves this by reducing the forces between polymer chains, thereby lowering the material's glass transition temperature. This results in increased elasticity and softness, crucial for applications ranging from wire and cable insulation to synthetic leather and flooring. The chemical properties of DOP, such as its excellent compatibility with PVC and good thermal stability, are fundamental to its effectiveness in these diverse industrial applications.

In recent years, there has been increased scrutiny regarding the safety of certain phthalates, including DOP. Concerns have been raised about potential endocrine disruption and reproductive effects associated with exposure to some phthalates. Regulatory bodies worldwide have responded by implementing restrictions or outright bans on specific phthalates in certain product categories, particularly those intended for children or medical use. While DOP has historically been a widely used plasticizer, the industry is actively responding to these concerns by developing and promoting alternatives. Understanding these discussions is vital for informed material selection.

NINGBO INNO PHARMCHEM CO.,LTD. is committed to ensuring that the products we supply meet all relevant safety and regulatory standards. We provide detailed technical data sheets and support our clients in navigating compliance requirements.
