Acetyl Hexapeptide-8 (CAS 616204-22-9)

Application and positioning

The best-known cosmetic hexapeptide: it moderates SNARE complex formation, softening the visible appearance of expression lines without any pharmacological claim. Supplied as a high-purity powder for aqueous serums and emulsions. Counter-ion and residual TFA content are the two specification points formulators ask about first. Laurand supplies it from audited Chinese producers in kilogram to multi-hundred-kilogram lots, with the purity and microbiological documentation cosmetic formulators require.
