For products like Personal Lubricant that come into intimate contact with private skin, the stability and safety of quality are the core concerns for consumers and the lifeline for brands. If there are large batch-to-batch differences, with quality varying, it will not only severely affect user experience but may also lead to safety issues, dealing a fatal blow to brand reputation. So, how can one ensure that every bottle, every batch of personal lubricant maintains a highly consistent, excellent quality?
Behind this is a complete set of scientific, systematic, and interlinked quality control logic. Source control is fundamental. This means strictly screening and auditing suppliers of all raw and auxiliary materials to ensure their qualifications are compliant and quality is stable. Before each batch of raw materials is warehoused, it must undergo rigorous inspection, including key indicators like purity, impurity content, and microbial limits; non-compliant raw materials are never put into production.
Refined management of the production process is core. In a 100,000-class dust-free cleanroom compliant with GMP standards, every step of production, from weighing, ingredient mixing, emulsification, and homogenization to filling and sealing, must be strictly executed according to Standard Operating Procedures (SOPs). Key process parameters are precisely monitored, with corresponding In-Process Quality Control (IPQC) to ensure semi-finished products meet preset quality standards, promptly identifying and correcting deviations.
Comprehensive testing of finished products is the final line of defense. After products are completed, they are not directly warehoused and shipped but must undergo a series of strict finished product inspections. This may include testing physicochemical indicators like appearance, color, odor, pH value, viscosity, and specific gravity; microbial limit testing; heavy metal residue testing; and accelerated stability tests or long-term sample retention observation. These 21 quality inspection steps act like a fine net, ensuring no potential quality defect is overlooked.
Through such strict, layered checks, the product difference between different production batches can be controlled to an extremely low level, for example, within 0.3%. This high degree of batch stability means consumers receive a consistently high-quality experience whenever they purchase, thereby building deep trust in the brand.
PINGCHUANG MEDICAL strictly implements GMP pharmaceutical production standards, uses medical-grade raw materials, and through as many as 21 quality inspection steps, precisely controls every link from raw materials to finished products. This ensures product microbial and heavy metal residues are far below industry standards, and the batch stability difference rate is below 0.3%. Choosing PINGCHUANG MEDICAL means choosing peace of mind and consistent high quality.
