Demeterherb: A Leading Cosmetic Grade Resveratrol Raw Material Manufacturer from China at CPHI Korea 2026

For skincare and supplement developers, sourcing resveratrol is rarely about a single ingredient name. Behind the phrase Cosmetic Grade Resveratrol Raw Material Manufacturer From China (https://www.demeterherb.com/pure-fermented-resveratrol-powder-99-cas-501-36-0-natural-trans-resveratrol-for-skincare-antioxidant-supplement-raw-material-product/) sits a fuller procurement question: where the active comes from, what form it takes, which documents arrive with each batch, and whether supply can hold steady across repeat orders. Resveratrol, a plant-derived polyphenol valued for its antioxidant activity, has to enter a formulation file as a defined specification, not a marketing word.

Demeterherb, the brand of Xi'an Demeter Biotech Co., Ltd., brings plant extracts, cosmetic ingredients, and related nutrition raw materials under one platform. Its resveratrol line includes water-soluble resveratrol 10%, resveratrol at 50%, 98%, and 99%, and customizable specifications. These options give formulators several entry points for different development paths. That specification-first approach will also shape Demeterherb's CPHI Korea 2026 presence at Stand K33, where pharmaceutical, nutraceutical, and cosmetic buyers can discuss resveratrol grades, sourcing routes, and documentation for their formulation needs.

Cosmetic Grade Resveratrol Starts with a Clear Raw-Material Definition

The evaluation begins with the material itself. Rather than treating "antioxidant" as a complete product description, buyers should confirm the active ingredient, sourcing route, test method, and documentation. On the Polygonum cuspidatum extract page, cosmetic grade resveratrol is identified as a white powder standardized to 98%, with HPLC listed as the test method. Demeterherb's wider range also includes water-soluble resveratrol 10% and resveratrol at 50% and 99%, while custom specifications can be discussed for project-specific requirements. The same page lists a COA on request and a 24-month shelf life. Clear inputs reduce guesswork when a formulation moves from bench trials toward commercial batches.

Two Sourcing Routes Give Formulators a More Specific Starting Point

Demeterherb's resveratrol information sets out several specifications and two sourcing routes. Standard resveratrol is available at 50%, 98%, and 99%, while a water-soluble 10% grade supports projects that prioritize dispersion. The botanical extract and fermented Trans-Resveratrol routes should not be read as one specification. Route and stated content together shape how a formulation team builds its shortlist and compares documents. The fermented material is produced through natural microbial fermentation, with stable Trans-Resveratrol as its primary active form, and the product page positions it for premium skincare and supplement formulations. The page also notes that the fermentation route avoids the solvent residues linked to some synthetic processes and supports batch traceability, points that matter to buyers building a clean-label story. That connects grade to end use while leaving unstated details, such as microbial or INCI data not published on the page, out of the decision. Each route maps to its own product page, with the fermented grade carrying CAS 501-36-0, which keeps sample requests and technical follow-up anchored to verifiable pages.

Purity, Test Method, and Documentation Form the Quality Review Core

Quality review does not end at a single purity number. It rests on the product name, active ingredient, test method, appearance, packaging, and available documents together. On the 98% botanical page, Demeterherb (https://www.demeterherb.com/about-us/) lists these as product parameters and offers practical packing choices: 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, details that speak to how an antioxidant powder holds up in transit and storage. HPLC is named as the test method, and a COA is available for documented review, alongside MSDS and TDS files that a purchasing team can check against incoming batches. At the company level, Demeterherb states that its factory operates to GMP standards and holds credentials including ISO22000, EU Organic, USDA Organic, Halal, Kosher, and FDA registration. Those enterprise credentials describe the quality system and international footing behind the business; they should be read as company background rather than as an organic claim for the resveratrol powder itself.

Cosmetic Ingredient Positioning Extends Beyond a Single Powder Specification

The fermented 99% Trans-Resveratrol grade sits within Demeterherb's cosmetic ingredients range and is described directly as a skincare-oriented antioxidant raw material. For a formulator, that placement moves the question from "does it contain resveratrol" to "does this specification fit the skincare system already in development." The product page points to typical uses across serums, creams, and masks, alongside nutrition supplement and functional cosmetic formats, and describes the active as a lipophilic antioxidant meant to support the skin barrier against everyday oxidative stress. Demeterherb also offers OEM and ODM support, so a brand can move from a stock specification toward tailored blending or private-label manufacturing without changing suppliers. Demeterherb has also published technical content on liposomal resveratrol for clean-beauty and longevity formulations, a sign that the company is discussing resveratrol in a liposomal delivery format as well as a standard powder. That material works as an internal reference for technical conversations, while stability, regulatory fit, and finished-product performance stay tied to each target market's requirements and project-level testing.

A China-Based Manufacturing Platform Supports International Ingredient Workflows

Xi'an Demeter Biotech Co., Ltd. is based in Xi'an, China, and was founded in 2017. Its business spans plant extracts, organic extracts, organic fruit and vegetable powders, natural food colors, and related raw materials, serving pharmaceutical, nutraceutical, nutrition supplement, functional food, functional beverage, and cosmetic companies. That cross-category base is what supports Demeterherb's positioning in the cosmetic raw-material space. The company holds independent import and export rights and works through air, sea, rail, truck, and express logistics partners, with a customer footprint that reaches more than 50 countries across the Americas, Asia, and Europe. For a cosmetic grade resveratrol project, this platform links inquiry, samples, documentation, and bulk delivery into one coordinated flow, and the word "leading" rests on these checkable capabilities rather than an unverified market ranking.

CPHI Korea 2026, scheduled for August 25-27 at COEX in Seoul, fits this international ingredient workflow rather than sitting apart from it. Xi'an Demeter Biotech Co., Ltd. is listed at Stand K33, giving buyers a venue to move from resveratrol route and specification questions into sampling, documentation review, and purchasing follow-up.
