Stability
While specific data for Methionyl SH-Polypeptide-101 is limited, other recombinant sh-Polypeptides are sometimes engineered as fusion proteins for enhanced stability and solubility. Larger polypeptide molecules may benefit from encapsulation in delivery systems like liposomes or nanoparticles to improve stability, penetration, and overall efficiency in topical applications.
Safety
Safety Profile
No specific safety assessments by the Cosmetic Ingredient Review (CIR), SCCS, or FDA have been found for Methionyl SH-Polypeptide-101. The CIR has broadly reviewed general categories of tissue-derived proteins and peptides, often deeming them safe for use as skin and hair conditioning agents, but this is a generalized classification rather than a specific assessment of this particular polypeptide.
