ISO 22716 audits are the standard way a brand verifies that a filler runs a cosmetic Good Manufacturing Practice system. The certificate proves that an audit happened, on a date, against a scope – and the scope is where most brands stop reading. A certificate covering warehousing does not cover filling, and a certificate from a previous site says nothing about the current one.
1. Read the scope and the date
The scope statement has to cover the activities the brand is buying: manufacturing, filling, packing, and the product categories involved. A certificate issued three years ago against a two-year cycle is expired or about to be. Check the accreditation body too – a certificate from a body without international accreditation is a piece of paper.
2. The clauses that matter
Document control, batch records, deviation handling, change control, cleaning validation, water system monitoring and training records. For a cosmetic filler, three are critical: batch traceability, cleaning validation between products, and the microbial control of the water system. A factory that cannot show a cleaning validation between a fragrance-heavy product and an unscented one has a cross-contamination risk the brand inherits.
3. The water system
Water is the ingredient with the highest microbial risk in any cosmetic plant. Ask for the water system schematic, the sanitisation schedule, the sampling points and the trend of microbial counts over the last twelve months. A factory that samples only at the outlet and never at the points of use is sampling the easiest place, not the risky one.
4. Batch records and traceability
Pick one recent batch of a product similar to yours and ask to see the record: the raw material lot numbers, the weigh records, the in-process checks, the fill weights, the release signature. A complete record takes twenty minutes to walk through. A partial one tells you that the batch records are reconstructed after the fact.
5. Deviation and change control
Ask how many deviations were raised in the last year, what the top three causes were, and whether any customer was notified. A factory with zero deviations is a factory that does not record them. A factory that can describe its deviations, its corrective actions and its notification process is a factory with a working quality system.
6. Cleaning validation
Between products, the line has to be cleaned to a validated standard. Ask for the validation protocol, the worst-case product pair used, and the analytical method applied – usually a visual check plus a residue swab. A line that relies on a visual check alone is acceptable for a rinse-off product and not for a leave-on serum.
7. Training and personnel
ISO 22716 requires documented training for everyone who touches the product or the line. Ask to see a training matrix with names, dates and topics, and ask who signs off on a new operator before they work unsupervised. In practice, the training record is the difference between a system that exists on paper and one that exists on the floor, and it is the first thing a serious auditor checks.
8. Commercial profile
A GMP-documented filler with a current certificate, MOQ from 2,000 units, a shared audit report available on request. See the production range and the supplier audit checklist for the questions to ask on site.
