Epoxidized Soybean Oil (ESO), identified by its CAS Number 8013-07-8, is a widely utilized bio-based chemical that plays a crucial role in enhancing the performance and safety of various polymer applications. As a leading supplier, NINGBO INNO PHARMCHEM CO.,LTD. offers high-quality ESO, providing businesses with a sustainable and effective solution. This guide delves into the key properties, benefits, and essential considerations when you decide to buy Epoxidized Soybean Oil.

Understanding Epoxidized Soybean Oil (CAS 8013-07-8)

ESO is produced from soybean oil through a chemical process known as epoxidation. This process involves reacting soybean oil with oxidizing agents, typically hydrogen peroxide in the presence of an acid catalyst, to convert unsaturated fatty acid chains into epoxide groups. This chemical transformation results in a pale yellow, viscous liquid with a mild odor and a low solubility in water.

Key Chemical Properties of ESO

  • CAS Number: 8013-07-8
  • Appearance: Pale yellow liquid
  • Epoxy Value: Typically ranges from 6.6% min (ASTMD1652-04)
  • Density: Approximately 0.988-0.998 g/cm³ at 20°C
  • Acidity: Low, often less than 0.5 mg KOH/g
  • Flash Point: High, typically above 280°C, indicating good thermal stability.
  • Iodine Value: Low, indicating a high degree of epoxidation.

These properties make ESO highly suitable for its primary applications as a plasticizer and stabilizer.

Benefits of Using Epoxidized Soybean Oil in Formulations

Incorporating ESO into your product formulations offers several distinct advantages:

  • Enhanced Flexibility and Softness: As a plasticizer, ESO increases the flexibility and pliability of rigid polymers, particularly PVC. This is critical for products like wire insulation, films, and automotive components.
  • Superior Heat and Light Stability: The epoxide groups in ESO serve as internal stabilizers, effectively scavenging acids and preventing polymer degradation caused by heat and UV radiation. This leads to improved product durability and color retention.
  • Non-Toxic and Environmentally Friendly: Derived from renewable resources, ESO is a safe and sustainable alternative to many synthetic plasticizers. Its non-toxic nature makes it ideal for food-contact materials, medical devices, and consumer goods. When you purchase Epoxidized Soybean Oil, you are choosing a greener option.
  • Good Compatibility: ESO exhibits excellent compatibility with a wide range of polymers, resins, and other additives, ensuring seamless integration into complex formulations.
  • Cost-Effectiveness: It often serves as a secondary plasticizer, allowing for partial replacement of more expensive primary plasticizers, thereby reducing overall formulation costs without compromising performance.
