Details
What it is
An acetylated octapeptide modelled on the N-terminal end of SNAP-25, a protein of the SNARE complex that mediates vesicle fusion. It is an extension of the better-known acetyl hexapeptide-8 by two residues, and is used as a cosmetic active under its INCI name.
Also sold as: acetyl octapeptide-3, acetyl glutamyl heptapeptide-3
- As suppliedLyophilised powder, cosmetic grade.
- Into solutionWater-soluble. Typically added to the water phase of a formulation.
Reconstitution and handling
Handling
- As suppliedLyophilised powder
- Sealed, refrigeratedMonths
- In solutionRefrigerate, use short-term
Concentration is mass divided by the volume you added. A 10mg vial made up to one millilitre of solvent gives 10mg per millilitre; to two millilitres, half that. Record the volume you used: a solution whose concentration is not written down is a solution you cannot use quantitatively.
The full procedure is on our reconstitution guide, with a concentration calculator; what is known about keeping these materials is on storage and stability. Bacteriostatic water and acetic acid are both in our catalogue and can be ordered with a product or on their own.
