Scenario 1 – Nutraceutical Tablet Production
A U.S. nutraceutical company needed 10 kg of 98 % (-)-Catechin for a new antioxidant capsule line. We provided a 30 % price advantage and shipped the material within 10 days, enabling the client to launch two weeks ahead of schedule.
Scenario 2 – Cosmetic Anti‑Aging Serum
A premium skincare brand required a micro‑encapsulated catechin with particle size <150 µm. Our OEM service delivered a custom‑coated product that increased serum stability by 45 % (shelf‑life testing). The brand reported a 22 % boost in repeat purchases after the launch.
Scenario 3 – Clinical‑Grade API for Phase II Trials
A biotech firm sourced 2 tonnes of GMP‑grade (-)-Catechin for a Phase II clinical trial. Our GMP‑certified facility met FDA DMF requirements, and we handled customs clearance, reducing total logistics cost by $120 k.
