Quality Control Of Gel Nail Polish Products

At BOZILN, quality is not the final test, but a belief instilled from the very beginning of a product's creation. It is the guiding principle for all actions, permeating every detail from concept to delivery. Our end-to-end quality system transforms abstract standards of excellence into an undeniably superior experience in every product you receive.

Quality Control

IQC

Strict Raw Material Access Control

In our view, raw materials are the most solid foundation for building the pyramid of product quality. They are not only the source of safety and efficiency, but also the first and most crucial strategic line of defense for fulfilling our commitment to excellence.

We have established a strict supplier access and audit mechanism. All core raw materials such as resins, monomers, and color powders are sourced from traceable and compliant channels. Each batch of raw materials must undergo multiple inspections such as component analysis, viscosity, purity, and color before entering the factory to ensure their stability and safety, eliminating quality hazards from the first step.

Based on in-depth research on the dynamic global regulatory landscape such as EU REACH and US FDA, we proactively conduct formula strategic reserves. The entire product line is free of HEMA, TPO, HPMA, and DI-HEMA. This design enables your brand to have significant first-mover advantages and market access resilience when shaping its own product operation cycle.

IPQC

Lean Production Process Monitoring

In our modern, Class 10,000 cleanroom, intelligent equipment and standardized processes form the cornerstone of precision manufacturing. This ensures that every product adheres to the same rigorous standards, making consistent excellence our most solid foundation.

Our production system begins with the precise execution of scientific formulations: Automated batching systems strictly adhere to parameters fully validated in laboratories, eliminating human error at the source and ensuring a high degree of consistency in product quality.

Subsequently, vacuum homogenization technology achieves complete and stable dispersion under controlled temperature and speed. This not only ensures micron-level pigment particle size and a dense, flawless colloidal structure but also deeply contributes to the product's superior leveling properties and stunning color saturation.

Finally, on a fully automated filling line, under constant environmental conditions, we precisely control filling accuracy, sealing, and packaging integrity to ensure that every product delivered to you is as perfect as ever.

FQC

Comprehensive Final Product Inspection Before Delivery

Our final product inspection before delivery is not only a pass/fail judgment, but also a systematic verification based on risk management.

Performance Testing

Photocuring Efficiency Evaluation

Under standardized lighting conditions simulating the end-use environment, quantitatively detect curing speed, surface hardness, and anti-tackiness to ensure the best user experience.

Durability Testing

Through a series of tests such as shear resistance and abrasion resistance, test the adhesion between the colloid and the nail and the hardness of the film layer after curing, and quantify the performance of the product during its service life.

Sensory Consistency Control

Relying on standard light boxes and a professional quality control team to ensure that sensory indicators such as color and viscosity are highly consistent with the standard product.

Safety and Stability Testing

Accelerated Stability Testing

Place samples in extreme high and low temperature environments to check for delamination, discoloration, or fogging, ensuring the product remains stable during long-distance transportation and in different climates.

Centrifugal Testing

Simulate transportation bumps through a high-speed centrifuge to verify the physical stability of the product.

Certification and Testing by Authoritative Institutions

We have complete international certifications, including FDA, ISO 22716, GMPC, HALAL, etc., proving that our production system and product safety meet international standards.

We hold valid MSDS, CPSR, and CPNP registrations to ensure transparent product information and compliance with entry into European and American markets. Regularly send finished products to third-party authoritative laboratories for heavy metal content and microbial limit testing to ensure that all indicators meet the requirements of the "Cosmetic Safety Technical Specifications".

Founder's Message

We deeply understand that customer trust is invaluable, and market regulations are the bottom line we must adhere to. Both are the driving forces behind our product iteration and continuous self-improvement. At BOZILN, quality is our commitment to our partners, customer expectations are our guiding light, and laws and regulations are our guiding principles; together, these three elements forge our path forward.
