Application areas

Tripeptide-2 is designed for cosmetic and personal-care formulations, particularly eye serums, eye creams and facial concentrates. Typical use includes:

Eye-care products targeting the appearance of under-eye puffiness and dullness
Firming and revitalising serums for the delicate periorbital area
Anti-ageing and skin-conditioning facial formulations
Premium skincare concentrates and multi-active peptide blends

It is supplied as a cosmetic raw material for formulators, brands and contract manufacturers. Not for diagnostic, therapeutic or ingestive use.

Storage and packaging

Store sealed at 2–8 °C, protected from light and moisture. For long-term storage, keep at −20 °C. Packed in amber glass vials for gram quantities, or double-LDPE bags inside aluminium foil bags with desiccant for bulk. Under these conditions, the lyophilised powder is stable for 24 months unopened. Reconstituted solution should be used promptly or stored as directed by the formulator.

Supply notes

We supply cosmetic peptide raw materials in bulk, with batch-specific COA, SDS and TDS provided with every shipment. Both standard grade and endotoxin-controlled grade (≤0.25 EU/mg) are available for formulators who require lower bioburden for sensitive eye-area products. Small-pack evaluation sizes (1–10 g) are available for new customers; volume-tiered pricing applies for kilogram quantities.

Our cosmetic peptide series covers a range of molecules including GHK-Cu, acetyl hexapeptides, palmitoyl peptides and other skin-conditioning actives. Please send your inquiry through the ECHEMI message centre; our sales team replies within one working day.
