SR-ESCHERICHIA COLI POLYPEPTIDE-1.

Insufficient Data / SKIN CONDITIONING

SR-ESCHERICHIA COLI POLYPEPTIDE-1 is a biotechnology-derived peptide engineered to act as a signaling molecule within the skin. It stimulates the skin's inherent repair processes, enhancing regeneration in mature skin, improving structural integrity, and visibly diminishing the appearance of wrinkles. This versatile ingredient also offers benefits as a humectant, skin conditioner, and protective agent.

Science

Mechanism of Action

Operating as a signaling peptide, SR-ESCHERICHIA COLI POLYPEPTIDE-1 activates the skin's endogenous repair mechanisms. It specifically mimics natural collagen fragments, thereby promoting the renewal of mature skin cells, reinforcing dermal structure, and contributing to a measurable reduction in visible wrinkles. Beyond its anti-aging capabilities, it provides hydration as a humectant, conditions the skin, and forms a protective film.

Stability

The stability of polypeptides produced in E. coli can be influenced by factors such as signal peptides, fusion tags, and fermentation conditions, including temperature and inducer concentration. Hydrophilic sequences, particularly those with charged residues, are known to enhance solubility and stability.

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk Unknown

The Cosmetic Ingredient Review (CIR) Expert Panel has not conducted a specific safety review for SR-ESCHERICHIA COLI POLYPEPTIDE-1, thus its status is 'not reviewed' with no established maximum concentration. While related *E. coli*-derived polypeptides are not flagged by EWG, and general protein/peptide safety is often acknowledged, this specific ingredient lacks a definitive 'safe as used' determination. The broader term 'sr-Polypeptide-1' is currently under 'unknown' status by CIR, indicating it's on a priority list for future evaluation.
