Application Track 1: Nrf2 Dietary Supplements & Hard Capsules

Acts as a premier ingredient for cellular age-defying and healthy immune aging claims. It promotes antioxidant defenses and enhances gut and cellular integrity.

R&D Directives: Use **SFP-NUTR-0100** (1.0%) or **SFP-STAB-1000** (10.0%) for direct compounding. Standard daily dosages of active sulforaphane range from 10mg to 50mg daily.

Application Track 2: Soluble Wellness Drinks & Advanced Bio-Actives

Delivers a robust broccoli extract superfood claim inside modern wellness beverage mixes, boosting natural detoxification and immunity marketing angles.

R&D Directives: Incorporate **SFP-STAB-1000** (Microencapsulated 10.0%) to prevent clumping and mask sulfurous aromas, or leverage **SFP-PHAR-9800** (98.0%) for concentrated clinical formulations.

Application Track 3: Anti-Pollution & UV Recovery Skincare

Activates intracellular protective pathways in dermal layers, reducing the appearance of environmental stressors, redness, and dark spots caused by UV radiation.

R&D Directives: Blend **SFP-COS-0050** (0.5%) at 0.1% to 1.5% in the oil phase or emulsion stage below 45°C to preserve active enzyme matrices.

Case Study 1: Re-Formulating a High-Potency Nrf2 Cell-Shield Complex (London, UK)

Operational Challenge: A functional supplement brand faced massive potency drops of over 40% during shelf-life tests due to un-stabilized, low-grade raw broccoli sprout powder.

The Technical Execution: The brand switched their formulation to our microencapsulated stable grade **SFP-STAB-1000** at a standardized 10.0% concentration.

✓ Commercial Outcome: Post-upgrade stability testing showed active Sulforaphane retention remained at ≥96.5% over 18 months, leading to full EU distribution and premium retail placement.

Case Study 2: High-Purity API Integration for Clinical Research (Boston, USA)

Operational Challenge: A clinical research institution required an ultra-precise, solvent-free, highly purified Sulforaphane standard without any trace botanical fibers or moisture.

The Technical Execution: We supplied our crystalline, high-purity **SFP-PHAR-9800** (98.0% Active Sulforaphane), manufactured under vacuum low-temperature synthesis.

✓ Commercial Outcome: The institution achieved perfect assay consistency with zero background interference, establishing a successful baseline for their therapeutic cellular trial phases.

Hermetic Pharmaceutical-Grade Aluminum Bags / Fiber Drums

Packed in medical-grade 1kg vacuum-sealed aluminum foil bags, further packed inside standard 25kg net-weight high-density fiber drums. This double-layer protective barrier prevents air ingress and moisture clumping.

Preservation & Cool-Storage Recommendations

For optimal preservation of enzymatic activity, store in sealed, dark containers under cool, dry conditions. While our 0.5%, 1%, and 10% grades are stable at room temperature, storing our 98% pure grade at -20°C (or under 2°C - 8°C cold chain) is recommended for long-term industrial stability.

Traceable Regulatory Quality & HPLC Verification Dossiers

Every shipment includes batch-specific trace-back documentation: Certificate of Analysis (COA), HPLC chromatogram profile, Myrosinase enzyme activity status, micro-biological safety sheet, and SDS files.

Q1: How do you solve the natural instability of Sulforaphane?

A: We utilize a proprietary microencapsulation technology that wraps active sulforaphane molecules inside a food-grade matrix. This effectively shields the compound from light, air, and moisture, extending its shelf-life significantly compared to standard un-stabilized powders.

Q2: What is the source of your Sulforaphane Powder, and how is it extracted?

A: Our powder is extracted strictly from premium, sustainably harvested Broccoli (*Brassica oleracea*) seeds, which contain much higher concentrations of the precursor glucoraphanin than mature plants. We use clean water-extraction at low temperatures, ensuring zero trace organic solvents like hexane or acetone.

Q3: What are the differences between your 0.5%, 1%, 10%, and 98% specifications?

A: We offer a versatile range to suit all application types: **0.5%** is optimized and deodorized for premium cosmetic serums; **1.0%** and **10.0%** are stabilized microencapsulated powders featuring active Myrosinase enzyme complex for optimal dietary bioavailability; **98.0%** is an ultra-pure, high-potency crystalline compound engineered for clinical R&D and pharmaceutical applications.

Q4: Does your Sulforaphane Powder have a strong, unpleasant broccoli/sulfur smell?

A: Regular broccoli sprout extracts have a very strong, sulfurous odor. However, our cosmetic grade **0.5%** and microencapsulated **1.0% / 10.0%** grades undergo a specialized, gentle deodorizing isolation step. This significantly reduces odor volatility, making them excellent for sensitive topical creams and palatable wellness drink mixes.

Q5: What is your MOQ, and do you supply documentation for customs clearance?

A: Our commercial MOQ is 25kg (one fiber drum). For premium research formulations, R&D trials, or clinical softgel pilot validation, we support procurement teams with 20g - 50g free evaluation samples alongside a complete COA and HPLC batch chart.
