About R-(METHIONYL SH-POLYPEPTIDE-10 DECAPEPTIDE-40)
A recombinant fusion peptide with R-enantiomer designation, produced in E. coli and used for skin anti-aging and firming applications.
Detailed Analysis
R-(Methionyl sh-Polypeptide-10 Decapeptide-40) is a single-chain recombinant peptide produced by E. coli fermentation with a synthetic gene coding for the sh-Polypeptide-10 and Decapeptide-40 fusion. The R- designation may refer to stereochemistry at the N-terminal methionine or a specific structural variant. The ingredient follows the same production platform as other E. coli-expressed cosmetic peptides. Safety assessment follows standard recombinant protein principles; endotoxin removal and purity verification are the primary quality concerns.
Skin Benefits
- ✓ Dual peptide structure targets multiple anti-aging mechanisms
- ✓ May support natural skin matrix protein synthesis
- ✓ Recombinant production ensures batch-to-batch consistency
Known Concerns
- ⚠ Endotoxin concerns from E. coli expression system
- ⚠ Purity and complete sequence confirmation required
- ⚠ D-specific amino acids (if any) may have unknown degradation products
Safety Score
Good
Based on EU regulatory data, published safety research, and ingredient function analysis.
