The Formula
Formulation
Stability
The optimal pH range for DIPEPTIDE-21 is currently unknown. Peptide stability is generally pH-dependent, with various degradation pathways occurring at different pH levels (e.g., acid-catalyzed hydrolysis at pH 1-3, degradation at pH 5-6, and base-catalyzed epimerization at pH > 7). Peptides are often water-soluble, especially with charged residues, and solubility can be enhanced by TFA salts.
Conflicts
- strong antioxidants (e.g., ascorbic acid, for some copper peptides)
- glycerol (for some peptides, due to condensation reactions with reactive impurities)
Safety
Safety Profile
DIPEPTIDE-21 has not undergone formal safety assessments by regulatory bodies such as the CIR Expert Panel, SCCS, or FDA. While general peptide safety for topical use has been noted at concentrations below 10 ppm, specific concentration limits or sensitization risks for DIPEPTIDE-21 are currently unavailable.
