(1) Enforced Quality Standards
The product is manufactured in strict accordance with ISO22716 cosmetic raw material production specifications and international advanced peptide raw material quality control criteria. A full-process quality control system is implemented covering raw material incoming inspection, solid-phase synthesis, purification chromatography, sterile filtration, freeze-drying packaging and finished product sampling test. Each batch of products is assigned a unique batch number to realize full traceability of production procedures, test data and outbound records.
In terms of raw material control, all amino acid monomers used for synthesis are high-purity grade raw materials sourced from well-known domestic and international suppliers, with official factory inspection certificates attached for each batch to ensure raw material quality. Automatic peptide synthesizers are adopted for solid-phase synthesis with fixed program parameters to avoid manual operation errors. Preparative reversed-phase HPLC columns are used for multi-stage gradient elution purification, effectively removing peptide fragment impurities, missing-sequence substances and synthesis byproducts to ensure high-purity finished products.
All freeze-drying processes are completed in a negative-pressure 10,000-class GMP clean workshop. 0.22μm sterile filter membranes are used for impurity and microbial removal. The optimized freeze-drying process includes three precise control stages: pre-freezing, primary sublimation and secondary desorption drying, which maximizes the removal of free moisture and effectively prevents peptide hydrolysis and activity loss. Split packaging is carried out in a local 100-class laminar flow clean area. All glass vials are sterilized by high-temperature dry heat, and stoppers & aluminum caps are disinfected via ethylene oxide to ensure zero external pollution during production.
(2) Multi-level Factory Inspection Procedures
Level 1: In-process Online Inspection After synthesis, crude product samples are collected for preliminary HPLC purity screening. Any unqualified semi-finished products will be re-purified immediately and will not enter the next production process.
Level 2: Semi-finished Product Inspection Before sterile filtration and freeze-drying, samples are tested for microbial safety, endotoxin index, pH value and solubility. The subsequent packaging process will be suspended if any index fails to meet standards.
