Key Selection & Technical Criteria
A suitable peptide must match finished formulation requirements rather than general descriptions.
Peptide Identity
Request complete identifiers including INCI name, chemical name, CAS number, molecular weight, sequence (where applicable), and active content grade.
Purity & Active Content
Interpret values based on supplied forms (powder, lyophilized material, aqueous solutions, or blends) and analytical methods.
Physical Form
Evaluate whether the ingredient is supplied as a powder, freeze-dried solid, or liquid solution to calculate accurate weighing, dissolution, and processing metrics.
Formulation Compatibility
Review solubility, recommended pH ranges, temperature sensitivity, light/oxidation stability, and compatibility with standard cosmetic bases.
Reliable peptide raw materials require strict process control across the entire production chain:
Raw Material Control -> Peptide Synthesis -> Cleavage / Processing -> Purification -> Desalting / Concentration -> Drying or Formulation -> Quality Testing -> Batch Release -> Packaging & Storage
Manufacturing operations must connect production processes to measurable quality attributes, ensuring identity, purity, impurity profiles, and strict batch consistency across production lots.
