ISO 22716 does not create one universal air program

ISO 22716 provides Good Manufacturing Practice guidance for cosmetic products. It should not be interpreted as requiring every cosmetics room to follow sterile pharmaceutical grades or one fixed CFU limit. The monitoring program should reflect product formulation, water activity, preservative system, open processing, people, utilities, cleaning and historical microbiological performance.

The useful question is whether airborne contamination has a credible pathway to product or product-contact surfaces, whether the selected method can detect loss of control, and what action the result will trigger.

Use active sampling where exposure and consequence justify it

Active microbial air sampling is particularly useful near open bulk, exposed filling, unpackaged components, sensitive products, water-related operations and areas with repeated microbiological deviations. It may also support assessment after HVAC, layout, cleaning or process changes.

Sampling at rest can establish background condition, while in-operation sampling captures contributions from operators, equipment and interventions. Records should include line, product, shift, room state, cleaning status and relevant activities so results can be interpreted.

Combine complementary microbiological methods

An active sampler draws a defined air volume through an impactor onto growth medium. Settle plates measure gravitational deposition over time, surface methods assess contact areas, and personnel monitoring evaluates operator-related routes. Product and water testing provide additional outcome data.

Each method has limitations. Strong investigations and trend reviews connect multiple sources instead of treating one colony count as a complete description of environmental risk.

Set internal levels from evidence

Alert and action levels should be justified using baseline data, zoning, product risk, method capability and the consequence of contamination. Copying sterile-area limits or another factory’s limits can create false confidence or unnecessary investigations.

The procedure should define out-of-trend review, repeated recovery, organism identification, escalation, product impact and CAPA. A low count may still matter when the organism or location is significant.

MiniCapt and SAO NAM support

PMS describes MiniCapt Mobile as an active microbial air sampler that supports controlled-volume sampling and structured recipes when configured with the appropriate impactor and accessories. The instrument does not independently choose locations, media, incubation or acceptance criteria.

SAO NAM Life Sciences is the specialized Life Sciences representative of PMS and exclusive distributor of MiniCapt and BioCapt in Vietnam under the current authorization scope. Support is available for application assessment, configuration, official supply, qualification, training, calibration, maintenance and troubleshooting according to project scope.

Implementation and review controls

Program effectiveness should be reviewed periodically and after meaningful change. New formulations, preservative changes, different packaging, higher production volume, HVAC work, revised cleaning chemicals or recurring organisms can change the risk profile. Trend review should compare locations and operating states while accounting for method and incubation consistency. When an excursion occurs, avoid automatic resampling as the only response. Preserve the original result, review activities and environmental conditions, assess organism significance, connect product and water data, and document the rationale for containment and CAPA. This turns air sampling into a process-control tool instead of a collection of isolated CFU results.
