Build an ingredient enquiry that can be quoted accurately.
A clear enquiry reduces back-and-forth and makes supplier responses easier to compare. Start with the material identity, then define commercial and technical requirements.
| Include in your request | Why it matters |
|---|---|
| INCI name, CAS number or ELX code | Confirms the intended material identity. |
| Powder or solution format | Prevents different active contents from being compared as identical. |
| Target quantity | Allows MOQ, packaging and quantity-based pricing to be reviewed. |
| Destination market | Helps define delivery and documentation discussions. |
| Required file set | Clarifies whether you need COA, HPLC, MS, TDS, SDS or another declaration. |
Compare powder and solution formats before comparing price.
A peptide powder and an aqueous or glycol solution may share an INCI reference but differ in active content, carrier ingredients, preservation, packaging, storage and recommended use level. Compare cost per unit of active—not only gross price per kilogram.
| Check | Powder | Solution / complex |
|---|---|---|
| Active content | Confirm assay, purity and analytical basis. | Confirm concentration and complete carrier INCI. |
| Packaging | Often gram-scale or sealed bulk packs. | Usually liquid containers with batch-specific storage guidance. |
| Price comparison | Compare grade, purity and quantity. | Compare against active concentration, not gross weight alone. |
Know what each quality document supports.
Document availability should be confirmed for the exact product and batch scope. These file types answer different questions and should not be treated as interchangeable.
- COA: batch-specific quality results against the applicable specification.
- HPLC: chromatographic analysis when applicable to the material.
- MS: identity-related analytical information where available.
- TDS: technical handling, use-level and application information.
- SDS: safety, storage, transport and hazard communication information.
Use the portfolio as the start of the conversation.
The public portfolio does not promise stock, specification, regulatory status or finished-product performance. Select a product, then submit the actual grade, format, quantity and market requirements.
