Copper Gluconate Manufacturer for Food, Supplement, Feed and Cosmetic Formulation
Copper gluconate, also called cupric gluconate (CAS 527-09-3), is the copper salt of gluconic acid. It is used as a copper source or formulation ingredient in selected dietary supplement, food, feed, and cosmetic applications. Commercial qualification should be based on the destination market, intended use, elemental copper target, assay, impurity limits, solubility, and batch-specific documentation.
WIS Biotech manufactures food-grade and feed-grade copper gluconate in Shandong, China. Since 2015, our gluconate facility has supported ingredient distributors, contract manufacturers, premix producers, and formulation businesses in more than 80 countries. Buyers can request the current specification, SDS, recent batch COA, applicable certificates, samples, and a destination-based quotation.
Copper Gluconate Applications
Dietary Supplements and Multi-Mineral Formulas
Copper gluconate can be formulated into tablets, capsules, gummies, and mineral blends where it is permitted as a copper source. Formulators should calculate ingredient weight from the approved batch specification and verify serving level, ingredient interactions, sensory performance, labelling, and local rules in the finished product.
Food and Specialised Nutrition
Cupric gluconate appears in EU legislation as a permitted source of copper for food supplements and for the addition of minerals to foods. This does not establish suitability for every food category, age group, or specialised-nutrition product. Buyers serving infant, pediatric, or medical-nutrition markets must complete product-specific regulatory and supplier qualification before use.
Feed and Trace-Mineral Premixes
Feed-grade copper gluconate is supplied for trace-mineral premixes and other feed uses subject to the buyer’s species, formula, inclusion level, and local feed rules. Buyers should confirm authorisation of the specific copper source, the selected grade, production scope, and applicable documentation for the destination market.
Cosmetic and Personal-Care Formulation
Copper gluconate is included in the EU cosmetic ingredient nomenclature with skin-conditioning and skin-protecting functions. CosIng is an informative database and an ingredient listing does not itself constitute approval for cosmetic use. The finished-product responsible person must assess safety, restrictions, concentration, claims, and compliance under Regulation (EC) No 1223/2009 and other applicable rules.
Copper Gluconate Supplier: Procurement Checklist
- Define the application: state the product type, destination market, required grade, and target elemental copper contribution.
- Approve the specification: compare assay, copper content, pH, solubility, and impurity limits with a recent batch COA.
- Confirm documents: request the current specification, SDS, COA, origin documents, and certificates applicable to the selected grade and site.
- Set commercial terms: provide trial and annual volume, packaging, destination, requested delivery date, and Incoterm.

Packaging and Supply
Standard packaging is 25 kg net multi-layer kraft paper bags with an inner PE liner. FIBC options may be available for approved orders. Store sealed in a cool, dry, well-ventilated place away from direct sunlight and incompatible materials.
Commercial MOQ: 500 kg. Qualification samples of 1–5 kg are available subject to approval and stock. Standard lead time is generally 7–14 business days after order confirmation; final availability, loading, freight basis, and delivery schedule are confirmed in the quotation.
Quality and Documentation
Each commercial shipment is supported by a batch COA and SDS, with origin and shipping documents prepared for the agreed transaction. Controlled copies of applicable quality, food-safety, Halal, Kosher, and feed-scope certificates are available on request. Buyers should verify that each certificate covers the selected grade, production site, validity period, and destination-market requirement. WIS Biotech does not offer pharmaceutical-grade copper gluconate.
Frequently Asked Questions
How does copper gluconate compare with copper sulfate?
Both can supply copper, but they differ in elemental copper concentration, taste, counter-ion, serving size, and formulation behaviour. The suitable material depends on the intended application, destination-market authorisation, specification, impurity limits, and finished-product validation. WIS does not claim that one form is universally more absorbable or better tolerated than the other.
What elemental copper content does WIS Biotech specify?
The current page specification states 13.8%–14.5% elemental copper and 97.5%–102.0% assay on a dried basis. Formulators should use the approved specification and batch COA for dosing calculations and verify impurity limits for the intended market and product category.
Is WIS Biotech copper gluconate suitable for infant formula?
Suitability cannot be established from a generic food-grade description alone. Infant-formula buyers must confirm that the specific copper source is permitted in the destination market and complete product-specific review of purity criteria, contaminant limits, manufacturing controls, and supplier documents before approval. WIS can provide available technical and batch documents for that assessment.
What is the MOQ and lead time for copper gluconate?
The commercial MOQ is 500 kg. Qualification samples of 1–5 kg are available subject to approval and stock. Standard lead time is generally 7–14 business days after order confirmation, with final timing stated in the quotation.
Does a CosIng listing mean copper gluconate is approved for EU cosmetics?
No. CosIng is an informative European Commission database, and an INCI listing does not itself mean an ingredient is approved for cosmetic use. The finished-product responsible person must assess safety, restrictions, concentration, claims, and compliance under Regulation (EC) No 1223/2009 and other applicable rules.
Are Halal and Kosher documents available?
Controlled copies of applicable Halal and Kosher certificates are available on request. Buyers should confirm certificate scope against the selected grade, production site, validity period, and destination-market requirements before commercial approval.
Request a Copper Gluconate Quote
Request a quote or qualification sample and include the application, grade, target specification, trial and annual volume, packaging, destination, and Incoterm. Ask for the current specification, SDS, recent batch COA, and applicable certificates.
