Technical Specifications & Quality Parameters

You can select the right grade based on your specific needs by knowing the exact requirements.Our production process ensures that every batch has the same quality in all technical aspects.

Chemical and Physical Characteristics

The Thistle Extract Powder is a fine, light yellow to brownish-yellow substance that tastes somewhat bitter and has a distinctive faint odor. Its main active ingredients are silybin A and B isomers, which are members of the silymarin complex.

Solubility Profile: Standard grades dissolve easily in ethanol and acetone due to their lipophilic characteristics. We provide water-soluble grades made by cyclodextrin complexation for aqueous applications.​​​​​​​

Thermal Stability: The extract is great for making tablets and capsules because it stays stable up to 80°C during production.This ability to withstand heat ensures that the active ingredient works as intended throughout the manufacturing process.

Antioxidant Capacity: Significant free radical scavenging ability is demonstrated by high ORAC values, which provide functional advantages beyond primary applications.

Superior Manufacturing and Quality Control

Automated extraction lines with real-time monitoring systems are used in our production plant. Every batch is put through extensive testing, which includes microbiological analysis, residual solvent verification, and heavy metal screening.

USP and EP pharmacopoeia standards are adhered to in quality control. International safety standards are met when residual ethanol is below 5000 ppm. For consistent therapeutic efficacy, silybin ratios and silymarin content are confirmed by sophisticated analytical tools.

Microbial growth during storage is inhibited by the low moisture requirements. Excellent flowability in high-speed encapsulation machines is ensured by controlled particle size distribution, increasing your production efficiency.

Uses in the Health and Wellness Sector

Supplements for Liver Support: Hepatoprotective compositions that focus on cellular regeneration and detoxification are the most common application. Standardized silymarin administration helps your clients recuperate from environmental contaminants.

Detoxification Products: This substance is a key component of formulae that improve alcohol metabolism and recover from chemical exposure. The antioxidant qualities work well in conjunction with detoxification procedures.

Cosmetic Formulations: The protective properties of the extract are used in skin health products. Antioxidant properties aid in the creation of protective serums and anti-aging lotions.

Functional Beverages: You can expand your product offering into convenient formats by incorporating water-soluble grades into ready-to-drink health beverages.

Recommendations for Packaging, Storage, and Handling

Aluminum foil bags for 1–10 kg quantities and fiber drums for 20–25 kg volumes are examples of standard packaging. Both choices offer protection from exposure to light, moisture, and oxygen.

Keep out of direct sunlight and in cold, dry environments below 25°C. Ingredient stability is maintained for a full year in properly sealed containers. Process in well-ventilated spaces and steer clear of extended dust exposure.

Standard powder handling practices should be implemented at your plant. When weighing and combining, the fine particle size necessitates the use of suitable dust collecting equipment.

Frequently Asked Questions

Q: What distinguishes HPLC silymarin testing from UV testing?

A: Individual flavonolignans (50–60%) are measured by HPLC, whereas the entire silymarin complex (usually 80%) is measured by UV spectrophotometry. For pharmaceutical applications, HPLC offers more accurate therapeutic ingredient analysis.

Q: Is it possible for you to offer water-soluble grades?

A: We do provide improved solubility versions that are appropriate for liquid formulations and beverage applications using cyclodextrin complexation or specialized spray-drying.

Q: What paperwork is required for customs clearance?

A Certificate of Analysis, specification sheet, allergen statement, and certification copies (ISO, HALAL, KOSHER) are included with every shipment. When necessary, we help with country-specific regulatory paperwork.

Q: How can batch-to-batch uniformity be guaranteed?

A: Standardized extraction parameters are maintained by our automated production processes. Strict botanical identification procedures are followed when procuring raw materials, and each batch is subjected to multi-point quality testing before to release.
