Sebacates, as a class of organic compounds, are diesters derived from sebacic acid. These esters are known for a range of beneficial properties, including good thermal stability, excellent low-temperature fluidity, and lubricity, making them valuable in various industrial applications. Among the most commercially significant sebacates is Dioctyl Sebacate (DOS), a compound that embodies these favorable characteristics. NINGBO INNO PHARMCHEM CO.,LTD. is a leading provider of high-purity Dioctyl Sebacate, essential for numerous manufacturing processes.

Chemically, Dioctyl Sebacate is the di(2-ethylhexyl) ester of sebacic acid. Its molecular formula is C26H50O4, and it is characterized by two long, branched alkyl chains attached to the ester groups. These branched chains are instrumental in imparting low-temperature fluidity and preventing crystallization at sub-zero temperatures, a key factor in its widespread use as a cold-resistant plasticizer. The sebacic acid backbone provides a degree of thermal stability, while the ester linkages offer polarity and solvency.

The synthesis of Dioctyl Sebacate typically involves the esterification of sebacic acid with 2-ethylhexanol, often catalyzed by an acid or a titanate. The process requires careful control of reaction conditions to achieve high purity and yield. NINGBO INNO PHARMCHEM CO.,LTD. employs advanced manufacturing processes to ensure that its Dioctyl Sebacate meets stringent quality specifications, including high assay values, low acidity, and minimal moisture content.

The applications of Dioctyl Sebacate are diverse and span across multiple industries. As a plasticizer, it is highly sought after for PVC, nitrocellulose, and synthetic rubbers, enhancing flexibility and performance in cold environments. Its use in wire and cable insulation, films, and artificial leather highlights its ability to improve material properties under challenging temperature conditions. The low volatility and good compatibility with resins further solidify its position as a preferred plasticizer.

In the realm of lubricants, DOS serves as an excellent base stock. Its inherent lubricity, low pour point, and good viscosity index make it suitable for high-performance lubricants, including those used in aviation and demanding industrial machinery. The ester group's polarity also aids in the solvency of additives, ensuring a stable and effective lubricating formulation. NINGBO INNO PHARMCHEM CO.,LTD. supplies DOS that meets the specific requirements of the lubricant industry.

Furthermore, Dioctyl Sebacate finds application in the personal care industry due to its emollient properties and pleasant skin feel. It contributes to the smooth application and texture of cosmetics, lotions, and sunscreens. Its FDA CFR 21 compliance for food contact materials also broadens its utility into packaging and other sensitive applications.

In summary, Dioctyl Sebacate is a highly versatile chemical derived from sebacic acid, offering a unique blend of cold-resistance, lubricity, low volatility, and good solvency. These properties make it an indispensable component in plasticizers, lubricants, and personal care products. NINGBO INNO PHARMCHEM CO.,LTD. is committed to providing the market with a reliable and high-quality supply of Dioctyl Sebacate, enabling innovation and performance across various sectors.
