Snap-8 INCI Name: Acetyl Octapeptide-3
Snap-8 is a trade name; the INCI name is Acetyl Octapeptide-3. What to declare, what the quotation must state, and the naming traps around octapeptides.
Snap-8 sits alongside Argireline in most cosmetic peptide catalogues and shares the same naming trap: a trade name that is far better known than the substance it describes.
The name pair
| Trade name | INCI name |
|---|---|
| Snap-8 | Acetyl Octapeptide-3 |
How it appears on a label
Aqua, Glycerin, Acetyl Octapeptide-3, Panthenol, Phenoxyethanol
Two related entries exist in the inventory — other acetyl octapeptides carry different numbers. Declaring “Acetyl Octapeptide” without the number is incomplete, and declaring the wrong number is a mismatch between the product and the file.
What to check on the quotation
- INCI name including the number, in writing
- Powder or solution, and the concentration if it is a solution
- Lot COA with HPLC purity and MS identity
- Whether the material is supplied as the acetylated form stated in the COA
The last point is worth a moment. The acetylation is part of what the substance is, and the COA should confirm the identity of the specific peptide rather than describing it generically as an octapeptide.
Seen beside Argireline — a labelling warning
Because the two are usually offered together, formulators sometimes combine them and then shorten the declaration to save space on a small pack. Shortening an INCI name to fit is a filing problem, not a design choice: the declaration must match the inventory spelling, and if the pack cannot carry it, the answer is a different pack, not a shortened name.
Frequently asked questions
What is the INCI name of Snap-8?
Acetyl Octapeptide-3.
Is 'Acetyl Octapeptide' enough on a label?
No. The number is part of the name, and other acetyl octapeptides carry different numbers.
How is Snap-8 supplied?
Both powder and solution forms are common. The quotation must state which and at what concentration, because use levels differ.
Can I combine Snap-8 and Argireline in one product?
Yes, but each keeps its own INCI entry. Combining them does not create a combined name.
What should the COA confirm?
Identity by MS, purity by HPLC, the acetylated form, and the lot number matching the shipment.
