regarding the functionalityof the hygiene product, but it is a problemregarding
preciseanalyticaldataand physicalparametersfor product identification.
Exceptions to this rule are specificgoodmanufacturingpractice (GMP)
manufacturedproductsfor specificindustries, e.g. the pharmaceutical industry.
Suchproducts havemuch smallertolerancesregardingstandard deviationsand
by-products. They are also supplied withan elaborate analytical background.
A possible and practicalsolutionis the determinationofsummary parameters
of the main ingredientsand the definitionofacceptabledeviations. In most
casesa qualitative ratherthana quantitative result is sufficientfor quality
controlof the productsor product identification.
For thesepurposes,thereare variousquick tests,physicalinstrumentsand
analytical methodsavailablethat can be adapted to the required level of control.
39.3 Particular issues in tracing of hygieneproducts
Tracingof hygiene products maybe dividedinto five segments:
- Control of incominggoods,positive identification.
- Automatic control of preparing use-solutions.
- Control duringmanualhandling and refilling.
