Nonapeptide-1 ●
TL;DR. This ingredient is a skin-conditioning peptide used in brightening formulas to help modulate visible uneven tone. Its formulation role is as a low-level bioactive signal ingredient rather than a solvent, emulsifier, or preservative.
What does Nonapeptide-1 do in a cosmetic formula?
This ingredient is a skin-conditioning peptide used in brightening formulas to help modulate visible uneven tone. Its formulation role is as a low-level bioactive signal ingredient rather than a solvent, emulsifier, or preservative.
Is Nonapeptide-1 clean?
From a clean-beauty perspective, it is generally accepted and not a common restricted-list concern. The main caveat is that it is a synthetic biomimetic peptide, so it may not fit stricter natural-only standards.
Is Nonapeptide-1 sustainable?
This material is typically made by laboratory peptide synthesis, not direct agricultural extraction. It is expected to break down into amino-acid fragments over time, but its manufacture can involve specialty solvents and purification steps.
Is Nonapeptide-1 COSMOS-approved?
It is generally not permitted under COSMOS-natural or COSMOS-organic when made by conventional chemical peptide synthesis. Its low use level is favorable, but solvent-intensive synthesis is a Green Chemistry compromise.
How does Nonapeptide-1 work chemically?
The molecule is an amide-linked chain of nine amino-acid residues designed to interfere with alpha-MSH signaling at the melanocortin-1 receptor, which can reduce tyrosinase-related pigmentation signaling. It is typically used at very low active levels, often supplied in dilute aqueous or glycolic blends, and is best formulated in mild pH systems with attention to heat and protease exposure.
