Technical Profile & Extraction Excellence

Sesamin is the most prominent lignan compound found in sesame seeds (Sesamum indicum). As a premium lipid-soluble active ingredient, our Sesamin is manufactured using an advanced Supercritical CO2 Extraction and multi-stage recrystallization process. This ensures the highest possible concentration of the active molecule while maintaining a solvent-free profile.

The molecular structure of Sesamin consists of a unique 3,7-dioxabicyclo[3.3.0]octane skeleton with two 3,4-methylenedioxyphenyl groups. In industrial applications, this specific configuration provides exceptional oxidative stability, making it an ideal antioxidant synergistic agent for lipid-based formulations and high-end nutraceutical complexes.

Industrial & Formulation Advantages

Sesamin offers critical performance benefits for B2B manufacturers and product developers:

1. High Oxidative Stability & Synergistic Properties

In industrial oil-based formulations, Sesamin acts as a potent structural stabilizer. It effectively protects unsaturated fatty acids from oxidative degradation. When used in combination with Vitamin E (Tocopherols), Sesamin demonstrates a significant synergistic effect, enhancing the overall antioxidant capacity of the matrix without altering the organoleptic profile.

2. Superior Lipid Solubility for Softgel Formulations

Our ultra-pure Sesamin crystalline powder is engineered for optimal integration into lipid-based delivery systems. It dissolves clearly in carrier oils (such as MCT oil or Sesame oil) at controlled temperatures, ensuring a homogeneous suspension and accurate dosing in high-speed softgel encapsulation and liquid-fill hard capsule manufacturing.

3. Absolute Purity & Low-Impurity Profile

Through our proprietary purification technology, we remove unwanted waxes and pigments typically found in lower-grade extracts. The result is a high-purity crystalline powder with a neutral odor and consistent color, allowing for “clean label” formulations that meet the strict requirements of premium wellness brands.

Quality Management & Global Compliance

Our extraction facility is dedicated to sustainable botanical sourcing and advanced manufacturing excellence:

• Sustainably Sourced Raw Materials: We use only non-GMO sesame seeds with full batch-to-farm traceability.

• Solvent-Free Processing: Our extraction technology minimizes the use of harsh chemicals, ensuring compliance with strict European and North American regulations regarding residual solvents.

• Global Certifications: Fully certified under ISO 9001:2015, ISO 22000, HACCP, Kosher, and Halal. Complete documentation, including COA, MSDS, and Allergen Statements, is standard with every shipment.

B2B Application Matrix & Packaging

Sesamin is a versatile active ingredient suitable for various commercial applications:

• Premium Softgels: Focused on antioxidant and metabolic support formulations.

• Functional Skincare: Utilized as a lipid-stabilizing active in high-end anti-aging creams and serums.

• Dietary Supplements: Hard capsules and tablet blends (when used with appropriate excipients).

Standard Commercial Packaging: 25kg/Fibre Drum (Double-lined with PE bags). Small-scale trial quantities (100g, 1kg) are available for R&D validation and pilot-scale stability testing.
