For professionals in the chemical industry, particularly those involved in product formulation, a thorough understanding of chemical properties and synthesis pathways is fundamental. Ethylene Glycol Distearate (EGDS), identified by CAS number 627-83-8, is a compound whose chemical profile makes it invaluable across diverse sectors. As a leading manufacturer and supplier, we provide essential insights into the properties and manufacturing of EGDS, crucial information for any procurement manager or R&D scientist looking to make informed purchasing decisions.

Key Chemical Properties of EGDS

Ethylene Glycol Distearate is characterized by its specific physical and chemical attributes. It typically presents as a white to off-white solid, with a melting point often cited in the range of 79°C. This solid form is integral to its function as a pearlescent agent, where its crystallization upon cooling creates the desired visual effect. Its molecular formula is C38H74O4, with a molecular weight of approximately 594.99. While EGDS is almost insoluble in water, it exhibits solubility in organic solvents such as alcohol, acetone, and ethyl ether. These properties are critical for formulators to consider when integrating EGDS into various solvent systems or emulsions.

Understanding the Synthesis Process

The manufacturing of Ethylene Glycol Distearate typically involves the direct esterification of ethylene glycol with stearic acid. This reaction is often catalyzed by acids or metallic catalysts under controlled temperature and pressure conditions. The process yields the diester, EGDS, which is then cooled. The controlled cooling rate is essential for achieving the specific crystal structures that provide the characteristic pearlescent luster. For buyers seeking a consistent product, understanding that reputable manufacturers maintain strict control over these parameters ensures high-quality output. When you buy EGDS, you are essentially purchasing a product of carefully managed esterification and crystallization.

Sourcing High-Quality EGDS

As a B2B purchaser, sourcing EGDS requires diligence in selecting a manufacturer that adheres to rigorous quality standards. The chemical properties, such as melting point and solubility, should be verified through a Certificate of Analysis. Competitive pricing is also a factor, but it should not overshadow the importance of consistent purity and reliable supply. We, as a dedicated supplier, ensure that our manufacturing processes result in EGDS that meets the stringent requirements of cosmetic, personal care, and industrial applications. Consider us your trusted partner for all your EGDS procurement needs.
