I. Hygiene Indicators: The Benchmark for Safety
In the oral care industry, the microbial profile of silica is directly linked to the quality of the final product. Currently, the Chinese Industry Standard (QB/T 2346) sets rigorous requirements for silica used in toothpaste:
Monitoring Item | Industry Standard (QB/T 2346) |
Total Aerobic Microbial Count (TAMC) | ≤ 200 CFU/g |
Total Yeast and Mold Count(TYMC) | ≤ 100 CFU/g |
Specific Pathogens | Not Detected |
These strict limits represent a significant challenge for manufacturers, requiring sophisticated process control to ensure absolute compliance.
II. The Sterilization Core: 600–750°C Thermal Processing
Silica production possesses a natural physical advantage regarding sterilization. During the drying phase, materials undergo instantaneous high temperatures of 600–750°C. At this range, all microorganisms—including highly resistant bacterial spores—undergo irreversible thermal denaturation. This ensures a near-sterile output at the physical source.
III. Scientific Governance of Production Media: Water, Air, and Piping
Effective microbial control extends beyond the product itself to the meticulous management of all production media.
- Purification and Monitoring of Process Water
Wash water is the highest priority in microbial prevention.
A.Purification Technologies: We utilize Microfiltration (MF), Ultrafiltration (UF), Nanofiltration (NF), or Reverse Osmosis (RO). These systems effectively remove ions and organic matter.
B. Continuous Disinfection: Since trace colonies may remain in purified water, industrial systems integrate UV disinfection, Ozone (O3) sterilization, or chemical dosing to prevent biofilm formation on internal pipe walls.
- Cleanliness of Compressed Air and Piping Systems
- Air Source Purification: Air contacting the material must pass through multi-stage filters to intercept dust particles and bacterial carriers.
- CIP (Clean-in-Place) Systems:Equipment and pipelines undergo regular cleaning to remove physical debris, supplemented by steam or chemical sterilization to ensure “zero dead zones and zero residue.”
IV. Terminal Defense: Packaging Environment and Personnel Hygiene
- Environmental Control: Packaging rooms are maintained at constant temperature and humidity (18–26°C, RH 45–65%) with periodic spatial fumigation and disinfection.
- Automated Operations: Fully automated packaging systems significantly reduce bacterial load from dust while minimizing the risk of secondary contamination from human intervention.
V. JSJ (Jinsanjiang): Practicing High Industry Standards via Digital Technology
As the primary drafter of the industry standard QB/T 2346-2015 (Silica for Toothpaste in Oral Care Products), JSJ treats microbial control as a non-negotiable quality baseline.
- Digital Production Dashboards: JSJ has achieved full automation of the entire production flow. Core process parameters are monitored in real-time via data screens, ensuring drying temperatures and reaction flow rates remain in an optimal controlled state.
- Fully Enclosed Loop:Materials travel through hermetically sealed pipelines, achieving “contactless” production from raw material to finished product, minimizing human interference.
- Strict Internal Control Systems: Beyond standard monitoring, JSJ conducts weekly air sedimentation tests and high-frequency finished product sampling to ensure every ton of silica delivered to our global partners possesses superior hygienic stability.
Summary
Microbial control is a game of details. Leveraging our deep expertise as a standard-setter and our leadership in digital manufacturing, JSJ provides global oral care partners with certainty that exceeds industry standards, safeguarding consumer health every day.
