Dusting Analysis
RH-POLYPEPTIDE-52 is currently listed as not being utilized in cosmetic products, suggesting it is not subject to common overuse or 'dusting' in formulations.
The Formula
Formulation
Stability
Optimal stability for RH-POLYPEPTIDE-52 is observed within a pH range of 3-5, where buffer solutions are critical for minimizing deamidation and oxidation, and safeguarding disulfide bridges. Elevated protein concentrations may lead to aggregation and increased viscosity. To enhance stability, strategies include precise pH optimization, appropriate buffering systems, excipients, co-solvency, air exclusion, and storage at low temperatures protected from light.
Safety
Safety Profile
RH-POLYPEPTIDE-52 is designated as 'Not used in cosmetic products' by COSMILE Europe. While the CIR Expert Panel has assessed broader categories of proteins and peptides, a specific safety review for RH-POLYPEPTIDE-52 in cosmetic applications is unavailable. The FDA does not pre-approve cosmetic ingredients.
