Consider an illustrative handover in a cosmetic laboratory. A mixing vessel has a label saying “cleaned”, and yesterday’s log contains a tick and someone’s initials. The next analyst still cannot establish which procedure was followed, whether an observation needed attention or whether the vessel is ready for its intended use. A useful cleaning record helps the next person make that decision. It connects the cleaning activity with an identifiable item, an applicable procedure and a clear outcome. ## Understand the purpose and scope For cosmetic manufacturing, cleaning supports a broader system of contamination control. Great Britain’s official guidance identifies premises cleaning, equipment maintenance and current documentation as elements of good manufacturing practice. Laboratories should apply requirements according to their activities. ISO 22716 covers cosmetic production, control, storage and shipment, while its published scope excludes research and development. An R&D laboratory can still benefit from well-designed cleaning records, but its procedures should reflect its work and applicable obligations. The fields below are practical design suggestions. They are not a universal statutory form. ## Build the record around the actual work Start with information that helps another person reconstruct the activity: - **Item and location:** Use an equipment or area identifier precise enough to distinguish similar vessels, benches or accessories. - **Reason for cleaning:** Identify the scheduled task, change of use, spill or other trigger. Link relevant previous work where useful. - **Procedure:** Record the method identifier and revision used. Capture parameters or cleaning materials where the procedure requires them. - **Person performing the work:** Use an attributable name or identifier, with a reliable way to identify the person later. - **Activity date and time:** Record when cleaning occurred, including start and completion times where the sequence matters. - **Observations and checks:** Describe relevant findings and record the outcome against the applicable acceptance criteria. - **Exceptions and actions:** Link any issue to its owner, required action and agreed timescale. - **Review and use status:** Make clear whether review is required, whether it occurred and whether restrictions remain. A form should be proportionate. Repeatedly collecting information that nobody uses can obscure the details that support a decision. ## Keep activity time and entry time distinct A digital timestamp may show when someone saved a form. That does not necessarily establish when cleaning happened. Design the record to distinguish these events when they differ. If an entry is late, record the actual activity time as accurately as possible and identify the delayed entry according to the laboratory’s procedure. Do not silently substitute the entry time for the activity time or create a falsely precise history. Corrections should remain understandable too. Preserve the original information and make the correction attributable, with an explanation where needed. ## Record the outcome with appropriate limits FDA’s cosmetic self-inspection checklist addresses clean, maintained equipment and protection of cleaned equipment against subsequent contamination. This makes the condition after cleaning, and how that condition is protected, useful considerations when designing the workflow. A completed log records an activity. It does not by itself demonstrate that the cleaning process is effective. The appropriate inspection or testing depends on the equipment, residues, intended use and established procedure. Keep cleaning and any separate sanitisation or disinfection steps identifiable. Their purposes and methods can differ. A single “done” box can conceal which steps were actually performed. ## Make an exception visible In an illustrative example, an analyst cleaning vessel V-014 finds residue around a removable fitting. The record identifies the observation and keeps the vessel unavailable pending the action required by the laboratory’s procedure. The follow-up entry links the additional work, its performer and time, and the required check. If review is needed before reuse, that decision is recorded separately. If the observation raises questions about earlier work, the laboratory can assess that possibility using the relevant history. Discovering residue does not, on its own, establish which previous samples or batches were affected. ## Choose software features that support the workflow When evaluating software, look for equipment-linked records, access to the applicable procedure, separate activity and entry timestamps, attributable corrections, and visible outstanding actions. Check whether a completed cleaning task can remain pending review or restricted from use when necessary. Also test whether the full record, including changes and linked actions, remains understandable when exported. Paper records can support a well-controlled process. Digital tools are useful when they make the work easier to record, review and retrieve. Neither format substitutes for an appropriate cleaning method or an informed decision about readiness. Before adopting a form, ask a colleague who did not perform the work to reconstruct what happened. Their unanswered questions are a practical guide to improving the record. **Sources:** [GB cosmetics guidance](https://www.gov.uk/guidance/making-cosmetic-products-available-to-consumers-in-great-britain); [ISO 22716 public scope](https://www.iso.org/standard/36437.html); [FDA cosmetic self-inspection checklist](https://www.fda.gov/cosmetics/cosmetics-guidance-documents/good-manufacturing-practice-gmp-guidelinesinspection-checklist-cosmetics).
