China remains an important sourcing base for Kojic Dipalmitate (KAD), supported by chemical-synthesis capabilities, cosmetic-active R&D clusters, established export infrastructure, and a broad network of ingredient distributors and formulation partners. Trade data identified China as the largest exporting country by shipment count in this product category, with 477 recorded export shipments and a 33% share in the referenced dataset.
For professional buyers, selecting a supplier should not begin with price. It should begin with whether the supplier can repeatedly deliver the same specification, documentation package, packaging standard, and lead time from one lot to the next.
This is a procurement shortlist, not a laboratory certification or product endorsement. Companies were included based on public product listings, export visibility, cosmetic-ingredient focus, and apparent relevance to Kojic Dipalmitate supply.
The evaluation framework focuses on five practical factors:
- Product traceability: Ability to provide lot-specific COA, SDS, specification sheet, origin statement, and retained-sample policy.
- Technical capability: Understanding of Kojic Dipalmitate's oil-phase formulation behavior, purity control, color control, and stability requirements.
- Quality systems: Availability and verifiability of ISO, GMP, or equivalent quality-management documentation where claimed.
- Supply continuity: Evidence of export activity, realistic lead-time communication, and packaging suitable for international transport.
- Commercial fit: Sample availability, MOQ flexibility, response quality, and support for brand owners, contract manufacturers, and distributors.
A useful market signal is supplier concentration: between October 2023 and September 2024, three companies—Hangzhou Lingeba Technology, Hangzhou Rebtech Novel Material, and SOHO Aneco Chemicals—accounted for 69% of the Kojic Dipalmitate export activity recorded in the referenced trade dataset.
Kojic Dipalmitate, also called Kojic Acid Dipalmitate, is an oil-soluble derivative of kojic acid. Its CAS number is 79725-98-7, and it is generally supplied as a white or off-white powder for use in emulsions, creams, lotions, serums, soaps, and other oil-containing cosmetic systems.
Unlike kojic acid, Kojic Dipalmitate is designed for improved compatibility with oil phases and is commonly evaluated by formulators for color, odor, melting behavior, purity, solubility behavior, and formulation stability.
A professional purchasing specification should include more than "99% purity":
| Control Point | What to Request | Why It Matters |
|---|---|---|
| Identity | CAS number, INCI name, structural or analytical identification | Prevents substitution with a different kojic-acid derivative |
| Assay | Lot-specific test method and purity result | A headline purity number alone is insufficient |
| Appearance | Color standard, particle form, odor | Yellowing or odor can affect finished-product aesthetics |
| Melting range | Defined internal specification and test method | Helps confirm material consistency and process suitability |
| Residual solvents | Test method, limits, and lot result | Important for cosmetic risk assessment |
| Heavy metals | Individual element limits and testing method | Avoid vague "heavy metals compliant" claims |
| Microbiology | Relevant where the buyer's internal standard requires it | Important for sensitive finished-product applications |
| Stability | Retest date, storage conditions, and packaging description | Supports inventory planning and shelf-life management |
Important compliance note: CE and RoHS are generally not the main compliance framework for a cosmetic raw material such as Kojic Dipalmitate. Buyers should instead verify the documentation relevant to their destination market, product category, ingredient inventory status, safety assessment, labeling, chemical compliance, and customer-specific restricted-substance requirements.
Capacity and MOQ figures below are only those publicly disclosed in marketplace or supplier-facing listings. They should be reconfirmed in a written quotation because they may refer to total facility capability, a different product line, sample orders, or a previous production period.
| Supplier | Location / Focus | Publicly Disclosed Capacity or MOQ | Publicly Visible Quality Positioning | Suitable Buyer Profile |
|---|---|---|---|---|
| ZHENYIBIO TECHNOLOGY INC | Xi'an; natural plant active cosmetic materials | Request quotation | GMP-standard factory stated; R&D and integrated raw-material solutions stated | Small-to-medium brands needing responsive customization support |
| Hangzhou Lingeba Technology Co., Ltd. | Hangzhou; export-visible KAD supplier | Request quotation | Export-volume leader in referenced trade dataset | Buyers prioritizing export track record |
| Hangzhou Rebtech Novel Material Co., Ltd. | Hangzhou; personal-care actives | Request quotation | ISO 9001 stated in public supplier profile | Brands seeking skin-brightening active portfolios |
| SOHO Aneco Chemicals Co., Limited | Cosmetic, personal-care, food, and nutrition ingredients | Request quotation | High-tech cosmetic-raw-material positioning stated | Distributors and multi-ingredient procurement teams |
| Hubei Artec Biotechnology Co., Ltd. | Hubei; cosmetic active supplier | Request quotation | Export-visible in trade data | Buyers seeking alternate supply options |
| Xi'an Xinlu Biotechnology Co., Ltd. | Xi'an; botanical and cosmetic raw materials | Request quotation | Public marketplace product listings | Trial and small-batch buyers |
| Hunan World Well-Being Bio-Tech Co., Ltd. | Hunan; biotech and raw-material supplier | Request quotation | Public marketplace supplier presence | General ingredient sourcing |
| Qinmu Biotechnology (Jinan) Co., Ltd. | Jinan; cosmetic/industrial raw materials | 1 kg MOQ listed on some marketplace offers | Product availability visible publicly | Sampling and early-stage sourcing |
| Shaanxi Hongkang Biological Technology Co., Ltd. | Shaanxi; bioactive and chemical materials | 1 kg MOQ listed on some marketplace offers | Public product listings | Buyers comparing smaller commercial MOQs |
| Hebei Chuanghai Biotechnology Co., Ltd. | Hebei; chemical and biological raw materials | 1 kg to 10 kg MOQ appears across listings | Public marketplace supplier presence | Price benchmarking and qualification sampling |
Public listings show a wide MOQ range. For example, one supplier listing shows 1–10 kg as acceptable for trial orders and 25 kg for regular orders, while another advertises 100 g sample availability and a 1 kg usual MOQ. These figures are useful for initial screening but are not substitutes for a signed quotation or supply agreement.
ZHENYIBIO TECHNOLOGY INC is a Xi'an-based high-tech enterprise established in 2012, focused on natural plant active cosmetic raw materials and related ingredient solutions. The company states that it operates from the Xi'an High-tech Industrial Development Zone Free Trade Area and has more than 90% of employees educated to bachelor's degree level or above.

Main markets: Confirm directly.
OEM/ODM relevance: Clarify whether the supplier provides factory-origin documents, repacking services, or only trading support.
A 99% assay claim does not guarantee that two materials will perform identically. Differences in raw-material quality, color, melting characteristics, residual impurities, moisture, particle distribution, storage history, and packaging can create visible formulation differences.
Ask every shortlisted supplier for:
- Three recent lot-specific COAs
- The analytical method used for assay testing
- Retained samples from the quoted lot
- A sample from the actual intended production route
- Storage and transportation requirements
- A declaration describing manufacturing-site identity and trading-party role
A common purchasing failure is comparing Kojic Acid, Kojic Dipalmitate, and differently named kojic derivatives as though they were interchangeable. They are not.
Your purchase order should state:
- INCI name: Kojic Dipalmitate
- CAS No.: 79725-98-7
- Required assay and test method
- Appearance and color limits
- Packaging material and net weight
- Retest date
- Required documents
- Approved reference sample or batch-standard procedure
One of the least discussed sourcing checks is to compare the sample COA lot number with the commercial lot number. Some suppliers send a high-quality qualification sample but ship material from another production lot later.
To reduce this risk:
1. Keep a sealed retention sample from the approved lot.
2. Require pre-shipment COA approval for the commercial lot.
3. Include a batch-to-batch acceptance clause in the purchase contract.
4. Test the first commercial lot before releasing it into full production.
5. Define an agreed dispute process for out-of-specification material.
A PDF certificate alone is not verification. Use the certificate number and legal company name to check the record in IAF CertSearch, then confirm that the status is active, the scope matches the supplied product or activity, and the certified site is the actual operating site. IAF CertSearch identifies whether a certificate is valid, whether the certification body is accredited, and whether the accreditation body is an IAF MLA signatory.
Kojic Dipalmitate shipments should be planned around:
- Moisture and light protection requirements
- Drum or foil-bag integrity
- Destination-country customs documentation
- SDS classification and transport confirmation
- Incoterms, insurance, and port charges
- Buffer inventory for re-testing and customs clearance
- Temperature exposure during long transit periods
For a first order, it is usually safer to qualify a sample, then a pilot lot, and only then a regular production quantity.
China offers a wide selection of Kojic Dipalmitate supply options, but sourcing success depends on disciplined qualification rather than catalog comparison. The strongest long-term partners are those that can provide traceable batches, transparent technical documents, stable communication, realistic lead times, and consistent support as your order volume grows.
For brands, formulators, and distributors seeking a flexible partner for Kojic Dipalmitate and complementary cosmetic actives, ZHENYIBIO TECHNOLOGY INC is a practical first company to contact for samples, specification discussions, multi-active sourcing, and customized supply support. Its stated integrated model covers cosmetic raw-material R&D, production, and solution-oriented service for customers in more than 50 countries.
Request the full certificate, including certificate number, legal entity name, site address, scope, certification body, accreditation body, and validity dates. Search the certificate number or company name in IAF CertSearch, then ensure the status is "Active," the site matches the supplier's actual factory, and the scope is relevant to the activities claimed.
Not necessarily, but unusually low pricing should trigger additional verification. Ask for the assay method, impurity profile, color standard, residual-solvent information, batch COA, origin of key raw materials, and packaging details. Compare landed cost and failure risk, not only unit price.
Public listings range from sample quantities as low as 100 g to commercial MOQs of 1 kg, 10 kg, 25 kg, 100 kg, or more. The meaningful MOQ is the one tied to your required specification, packaging, documents, and shipment terms—not merely the number shown in a catalog listing.
This term can mean different things. For raw materials, support may include custom packaging, ingredient blending, documentation adaptation, formula recommendations, sourcing of complementary actives, or finished-product development through affiliated partners. Ask for a written scope of work rather than assuming full finished-cosmetic manufacturing capability.
Approve the sample specification first, place a pilot order, request pre-shipment COA and packaging photos, retain a reference sample, conduct identity and assay testing through your internal or third-party laboratory, and release the material only after it meets the agreed specification.
