Approval workflow
From ingredient inquiry to technical approval.
A clear first review helps procurement, formulation and quality teams ask the same questions before a grade moves forward.
Confirm the material
Match the INCI or local name, CAS, sequence, botanical source, salt form and production route to the actual grade being quoted.
Review the current lot
Read the specification and lot-specific COA together. Check the assay method, purity or marker basis, limits and reporting basis.
Check application fit
Screen solubility, dispersion, pH, color, odor, particle behavior, carrier content and processing conditions in the intended base.
Align the launch review
Confirm SDS, contaminants, labeling, claim boundaries and destination-market requirements before a finished product is approved.
Technical document set
What does each document help you confirm?
Document availability is grade- and lot-specific. Request the current file set for the material under review.
| Document | Buyer question |
|---|---|
| Specification | What identity, assay, appearance, storage and release limits define this grade? |
| Lot-specific COA | Does the current batch meet the stated specification, and which method and reporting basis were used? |
| TDS or technical data | How should the material be handled, dissolved, dispersed, added and screened in a formulation? |
| SDS | What are the relevant handling, transport, storage and workplace safety requirements? |
| Origin and process statement | Where does the material come from, and is the production route matched to the supplied form? |
| Stability or compatibility data | What evidence is available for light, heat, pH, packaging or the intended cosmetic base? |
Ingredient-specific review
The quality questions change with the ingredient.
One generic purity number cannot describe every cosmetic raw material. Start with the checks that match the material category.
Peptides and copper complexes
Confirm peptide sequence, salt form, peptide assay, copper content, HPLC or LC-MS identity and ICP-OES or ICP-MS copper testing.
Botanical extracts
Confirm species, plant part, extraction solvent, marker profile, caffeine or other limits, pesticide residues and microbial controls.
Marine polysaccharides
Review algae species, harvest origin, fucose, sulfate, molecular-weight profile, ash, iodine and heavy-metal controls.
Polyphenols and emerging actives
Check isomer or identity assay, related substances, particle size, solubility, light stability and the delivery format of the offered grade.
Before you request a quotation
Send a brief your quality team can use.
Include the ingredient and target grade, finished-product format, destination market, required documents and the performance or compatibility questions you need to screen.
For a faster comparison, also note whether you need a powder, solution, freeze-dried material, carrier-based grade or a specific marker or assay basis.
Useful information to include
- Ingredient, grade, marker or assay target
- Serum, cream, mask, scalp or other format
- Destination country or market
- Sample, COA, TDS, SDS or stability documents needed
- Powder or liquid preference and compatibility question
Transparent review boundaries
Current files matter more than a headline claim.
Public references and preliminary values help frame a project, but they do not replace the specification, TDS, SDS or lot-specific COA for the offered material. Certification, regulatory status, stability and market acceptance must be confirmed for the actual grade, supply entity and destination market.
