ISO 22716 provides GMP guidelines for the production, control, storage and shipment of cosmetic products. It addresses product-quality practices but does not prescribe a universal pharmaceutical Grade A, B, C or D classification for every cosmetic manufacturing room. The appropriate environmental control should be justified from the product and process.

ASEAN cosmetic GMP expectations also support controlled manufacturing conditions. The practical question is which contamination pathways can affect the cosmetic product, not which pharmaceutical grade can be copied into a room specification.

Water-rich formulations, weak preservation, natural raw materials, products used around the eyes, open mixing, manual additions, long holding times and open filling can create different risks. Dry powders, aerosols, creams and gels require different control strategies. Closed processing and robust cleaning may reduce airborne risk at some stages.

Personnel, material transfer, doors, maintenance and cleaning remain important sources. HVAC filtration, pressure, temperature, humidity and airflow should support the intended process. Requirements should be linked to product specifications and failure modes.

Airborne particle counting can support HVAC qualification, investigation and trending where a change in particle concentration is relevant to product or process control. It does not identify viable organisms and cannot replace microbial air, surface, water or product testing. Every measurement should have an associated decision or action.

Internal alert levels should be based on qualification, baseline data, process history and risk rather than imported without justification. Trends should be reviewed with bioburden, water, cleaning deviations, maintenance and complaints.

Lasair® particle counters can support air-cleanliness qualification, troubleshooting and monitoring. MiniCapt® active microbial air samplers can support viable air assessment where the risk evaluation requires it. The model, locations, frequency and limits should be selected from the cosmetics process rather than from a generic package.

SAO NAM is the Authorized Sales & Service Center of Particle Measuring Systems specializing in Life Science applications in Vietnam. SAO NAM Life Sciences is also the exclusive distributor of MiniCapt® and BioCapt® solutions in Vietnam under the current authorization scope. Support may include application review, configuration selection, training, calibration, maintenance and troubleshooting according to project scope.

The monitoring plan should be justified by the cosmetic product and process. Water-rich formulas, natural raw materials, open mixing, manual additions, warm holding, filling exposure and difficult-to-clean equipment can create different contamination pathways. Map these pathways and identify where airborne particles are a useful process indicator versus where microbial, surface, water, differential-pressure or cleaning controls provide stronger evidence. Define alert levels from qualification and operating history rather than importing pharmaceutical limits without rationale. Reassess the program after changes in formulation, packaging, room layout, personnel flow, HVAC, cleaning chemistry or production volume. This risk-based approach supports ISO 22716 quality objectives while keeping measurement effort focused on decisions that protect product quality.

Before release, the site should confirm that the approved procedure, configured equipment, user training, raw data, review records and deviation process all describe the same workflow. Technical statements should be traceable to the current controlled standard or manufacturer document. Any site-specific limit, sampling duration or acceptance rule requires an approved rationale. Periodic review should compare the original assumptions with operating trends, changes, investigations and maintenance history. This final alignment is what allows a technically capable instrument or system to remain reliable and audit-ready throughout routine use.
