About
A numbered synthetic pentapeptide used for cosmetic conditioning claims. Low hazard at ppm use; efficacy and long-term safety largely supplier-reported.
Pentapeptide-119 is a proprietary synthetic five-amino-acid peptide in the numbered-INCI series, used for skin and hair conditioning claims at low ppm levels. Defined synthetic peptides generally have low irritation and sensitization profiles; the peptide is too small to trigger significant immune responses in most cases. No SCCS or CIR monograph exists for this specific peptide, and independent efficacy data is limited. Purity (residual protecting groups, solvents) and stability of the peptide in finished matrices are supplier-dependent. Typical use is in premium skincare and hair-care serums at very low inclusion. Default-down rubric applies to unreviewed numbered peptides.
