Demeterherb to showcase cosmetic-grade resveratrol at CPHI Korea 2026

Demeterherb, the brand of Xi'an Demeter Biotech, will use CPHI Korea 2026 in Seoul to present resveratrol raw materials for skincare, nutraceutical and supplement buyers. The company is highlighting multiple grades, two sourcing routes and documentation support for formulators looking to compare specifications and supply options.

Why it matters: - Resveratrol sourcing for skincare and supplement development depends on more than ingredient name. Buyers need defined grades, test methods, batch documents and stable supply. - Demeterherb is positioning its resveratrol line around those procurement needs ahead of CPHI Korea 2026. - The company is using the event to connect formulation teams with specification review, sampling and purchasing follow-up.

What happened: - Demeterherb, the brand of Xi'an Demeter Biotech Co., Ltd., will exhibit at CPHI Korea 2026 at Stand K33. - The show is scheduled for Aug. 25-27 at COEX in Seoul. - Demeterherb is presenting resveratrol raw materials for pharmaceutical, nutraceutical and cosmetic buyers. - The company is also directing teams to its company announcement for sample and inquiry support.

The details: - Demeterherb's resveratrol range includes water-soluble resveratrol 10%, standard resveratrol at 50%, 98% and 99%, plus customizable specifications. - On the Polygonum cuspidatum extract page, cosmetic-grade resveratrol is listed as a white powder standardized to 98%, with HPLC as the test method. - The same page lists a COA on request and a 24-month shelf life. - Standard packaging options include a 1 kg aluminum foil bag, a 25 kg carton and a 25 kg fiber drum. - The fermented grade adds foil bag and drum options with nitrogen flushing and light protection. - HPLC is named as the test method across the resveratrol pages. - COA, MSDS and TDS files are available for review. - Demeterherb states that its factory operates to GMP standards and holds ISO22000, EU Organic, USDA Organic, Halal, Kosher and FDA registration. - Those credentials describe the company’s quality system and export footing, not a product-level organic claim for the resveratrol powder.

Between the lines: - Demeterherb is separating botanical extract and fermented Trans-Resveratrol as distinct sourcing routes, not interchangeable labels. - The fermented material is produced through natural microbial fermentation and is positioned around stable Trans-Resveratrol as its primary active form. - The company says the fermentation route avoids solvent residues linked to some synthetic processes and supports batch traceability. - Demeterherb also offers OEM and ODM support, which can help a buyer move from a stock specification to private-label or tailored blending work. - The company's technical content on liposomal resveratrol suggests it is also trying to capture clean-beauty and longevity formulation interest. - Xi'an Demeter Biotech was founded in 2017 and is based in Xi'an, China. - The business spans plant extracts, organic extracts, fruit and vegetable powders, natural food colors and related raw materials. - The company says it serves customers in more than 50 countries across the Americas, Asia and Europe.

What's next: - Buyers at CPHI Korea 2026 can compare resveratrol grades, request samples and review documentation at Stand K33. - Formulation teams can use the event to check whether the botanical or fermented route fits their target application. - The next step for procurement teams is batch-level verification of COA, specification and packaging details before commercialization.

The bottom line: - Demeterherb is pitching resveratrol as a specification-driven ingredient business, not a single powder. The company is betting that documentation, route selection and export-ready logistics will matter as much as purity number for global buyers.
