Cosmetic peptide powder products organized for B2B search and sourcing.
Browse six product routes: core peptide powders, lyophilized formats, single cosmetic peptide ingredients, function-led blends and custom vial kits. Each quotation is matched to the specification, pack format and project scale you actually need.
Six product series
Pure Peptide Powder Series
Core cosmetic grade powders, multi-peptide systems and raw material options.
Lyophilized & Freeze-Dried
Powder and vial formats with handling and packaging controls.
Single Peptide Ingredients
A focused catalogue of widely requested cosmetic peptide ingredients.
Functional Peptide Powder
Formulation concepts grouped by desired cosmetic positioning.
Custom Peptide Powder Kits
Semi-finished, vial-plus-solvent and private-label project routes.
Need a peptide not listed?
The catalogue is a sourcing guide, not a closed list. Send the INCI name, target specification or reference requirement for a feasibility review.
Products: what professional buyers should verify
Products should be sourced against an exact cosmetic project specification rather than compared only by a trade name or headline purity. The applicable specification, batch documentation and finished-formula assessment remain the controlling references.
Identity and specification
Confirm the complete ingredient identity, physical format, composition basis and analytical method. Purity or assay values are only comparable when the material basis and test method are understood.
Formulation fit
Review solvent system, pH, processing temperature, addition sequence, exposure time and packaging compatibility with the qualified formulator responsible for the complete cosmetic formula.
Quality documentation
Request the product specification and the available COA, TDS and safety information for the shortlisted material. Final acceptance must use documents applicable to the ordered product and batch.
Commercial pathway
Align sample size, MOQ, pack format, artwork, lead time and forecast before scale-up. Bulk powder, filled vial, paired-solvent kit and private-label routes require different controls.
Recommended RFQ information
Include the target ingredient or function, intended cosmetic format, destination market, estimated quantity, packaging preference, required documents and launch timing. If a target purity or concentration is specified, identify whether it applies to the active peptide or the complete supplied powder.
Development and claims boundary
Raw-material information supports professional assessment but does not guarantee a finished-product result. Safety, stability, compatibility, directions and cosmetic claims should be evaluated for the complete formula and target market. This site does not position its products for injection, treatment of disease or other therapeutic use.
Can specifications be customized?
Target criteria can be discussed during feasibility review, but availability depends on the ingredient, analytical method, batch route, quantity and packaging program.
Which documents can be requested?
Available specification, COA, TDS and safety documents can be supplied for shortlisted products. The final document set is confirmed for the ordered item and batch.
Can this product be supplied under private label?
Private-label feasibility depends on formula, pack format, quantity, target market, artwork and required validation. Submit a project brief for a route-specific quotation.
Reference framework: Review target-market requirements using authoritative resources such as FDA guidance for cosmetic ingredient suppliers, the European Commission CosIng database and the ISO 22716 overview. Market suitability must be assessed for the final product.
How buyers should read and compare the product catalog
A catalog is most useful when it helps the buyer compare identity and evidence, not only names. Begin with the peptide, sequence or CAS reference, then verify counterion or salt form, molecular basis, purity method, available grade, packaging and intended development route. The product table presents known parameters and deliberately marks unverified values for confirmation against the current specification. That prevents a generic database value from being mistaken for a batch release result. The questions below explain how to read the catalog, why chromatographic purity is not the whole quality profile, and what information is required for an unlisted or custom product. Use the catalog to define the request; use the quotation, specification and batch documents to approve responsible supply.
- Identity and intended grade
- Format, quantity and destination
- Specification and batch evidence
- Claims and regulatory responsibility
How should I compare two peptide powder listings?
Match identity first, then compare salt or counterion form, sequence, molecular weight, target purity, analytical methods, appearance, water or residual-solvent controls, storage, packaging and intended grade. A product name alone is not enough for technical equivalence.
Does a stated purity describe the complete quality profile?
No. Chromatographic purity is one result under one method. Identity, related substances, water, residual solvents, counterions, peptide content, microbiological controls, endotoxin or sterility may also matter according to grade and intended use.
Why are some catalog parameters marked for confirmation?
Reliable values must come from the current product specification and batch documentation. The site avoids filling missing fields with generic numbers because salt form, analytical basis, packaging and manufacturing route can change the correct value.
Can an unlisted peptide be requested?
Yes. Send the name, sequence or reference identifier, required quantity, purity, modification, format, analytical package and intended development stage. Feasibility is reviewed before a custom synthesis or sourcing route is proposed.
