Myristoyl Pentapeptide-17 ●
TL;DR. This ingredient is a hair and skin conditioning signal peptide used mainly in lash, brow, and targeted eye-area formulas. It is included at very low levels to support the look of fuller, healthier hair fibers and improve conditioning claims.
What does Myristoyl Pentapeptide-17 do in a cosmetic formula?
This ingredient is a hair and skin conditioning signal peptide used mainly in lash, brow, and targeted eye-area formulas. It is included at very low levels to support the look of fuller, healthier hair fibers and improve conditioning claims.
Is Myristoyl Pentapeptide-17 clean?
Clean-beauty programs generally treat it as a low-use synthetic active rather than a major restricted-list concern. Eye-area use makes irritation testing and preservative quality important, but the molecule itself is not a common fragrance allergen or sensitizer.
Is Myristoyl Pentapeptide-17 sustainable?
This material is produced by chemical peptide synthesis with a fatty-acid tail, so it is resource-intensive compared with simple plant oils or mineral salts. The peptide portion is expected to break down biologically, but the upstream solvent and reagent burden gives it a middling Green Chemistry profile.
Is Myristoyl Pentapeptide-17 COSMOS-approved?
It is not a straightforward COSMOS-natural or COSMOS-organic fit because chemically synthesized, acylated peptides are not automatically aligned with those standards. From a Green Chemistry view, its low use level helps, but synthesis complexity and solvent use keep it in the yellow zone.
How does Myristoyl Pentapeptide-17 work chemically?
The molecule is a lipidated five-amino-acid peptide, pairing a C14 fatty chain with a short peptide segment to improve surface affinity and formula compatibility. Commercial blends are usually dosed at low percentages while the active peptide itself is present at ppm-level concentrations, and formulators typically add it during cool-down in mildly acidic to neutral systems to limit degradation.
