Full-Chain Quality Assurance System
Adhering to the principle that "Quality is built in through design and refined in manufacturing," Implements a four-stage quality inspection process that spans the entire product lifecycle. This ensures that every product meets the highest standards.
1. Incoming Quality Control (IQC)
Sample Inspection: Samples are taken from all arriving raw materials (abrasives, fluoride, flavors, etc.) and packaging materials (tubes, cartons).
Key Indicator Testing:
Raw Materials: Purity, particle size distribution, microbial limits, and moisture content are tested.
Packaging Materials: Dimensions, seal integrity, printing accuracy, and material compliance are checked.
Release Handling: Only batches that pass inspection are stored in the warehouse and approved for production use.
2. In-Process Quality Control (IPQC)
Real-time monitoring on the production line ensures critical process parameters remain controlled.
Material Feeding Verification:Confirmation that the type, sequence, and weight of materials fed into the process strictly match the formula.
Semi-Finished Product Testing:After mixing, samples are tested for viscosity, pH, relative density, color, and taste to ensure uniform texture.
Environmental Monitoring:Continuous monitoring of the production workshop's temperature, humidity, air pressure differentials, and microbial levels.
3. Final Quality Control (FQC)
Final release inspection is conducted on fully packaged products.
Visual Inspection: Packaging is checked for damage, print clarity, and cleanliness.
Net Content Check: Ensures product net content complies with regulatory requirements.
4. Retention Sample Stability Testing
Batch-by-Batch Retention: A specified quantity of samples is retained from every production batch.
Continuous Monitoring: Retained samples are placed under controlled temperature and humidity conditions for long-term stability studies. Their physicochemical and microbiological indicators are monitored throughout the product's shelf life to guarantee stability.
Through this interlocking quality inspection process, We have built a comprehensive quality firewall, delivering safe, stable, and effective oral care products to every customer.
