Langues : Anglais (eng) Catégories : Caractérisation Eau -- Epuration -- Traitement biologique Eau -- Qualité Microbiologie Index. décimale : 668.5 Parfums et cosmétiques Résumé : Part 1 describes the types of water that are generally available and how they are to be characterised from a chemical and microbiological point of view. For use in the production of cosmetic products (water as a raw material and water for cleaning purposes), certain microbiological quality requirements must be specified for the water. This is usually done by assigning microbiological purity requirements. These include, on the one hand, limiting the total viable count (TVC) (drinking water limits are usually used as a minimum standard) and, on the other hand, excluding certain specified microorganisms. In order to provide water of the desired quality, a suitable treatment system is required. The system must be designed to provide sufficient antimicrobial treatment of the water (there are various methods available). In addition, the water must be kept in constant circulation to prevent the accumulation of microorganisms (avoidance of biofilm!). Note de contenu : - 1.

Langues : Anglais (eng) Catégories : Eau -- Analyse Eau -- Qualité Echantillonnage Ingrédients cosmétiques Microbiologie Qualité -- Contrôle Index. décimale : 668.5 Parfums et cosmétiques Résumé : Part 2 outlines how water used as a raw material or for cleaning purposes in the manufacture of cosmetic products should be tested in microbiological control studies to ensure that it meets the microbiological quality requirements. For this purpose, samples must be taken from the water treatment system. Samples should be taken according to a defined sampling plan, based on the history of results in terms of number of samples and sampling frequency, at different points in the plant. Sampling points must allow adequate sampling. Sample quantities should be sufficient for the chosen method of analysis. Requirements for transport and storage of samples must be fulfilled. Samples must be analysed by specified appropriate methods, e.g. based on the methods of the Drinking Water Ordinance (German). The methods should be selected in such a way that it is possible to determine the number of bacteria (quantitative) and also to identify the species of microorganisms found (qualitative) and to evaluate the results with regard to the quality requirements.

Maksym, Auteur ; Joelle Nussbaum, Auteur ; M. Pflock, Auteur ; U. Rossow, Auteur ; Rainer Simmering, Auteur Année de publication : 2024 Article en page(s) : p. 38-42 Langues : Anglais (eng) Catégories : Analyse des défaillances (fiabilité) Cosmétiques Cosmétiques -- Aspect sanitaire Désinfection Eau -- Qualité Ingrédients cosmétiques Microbiologie Production Index. décimale : 668.5 Parfums et cosmétiques Résumé : Part 3 focuses on common failures related to the provision of water (as a raw material and for cleaning) for the manufacture of cosmetic products, which may pose risks to the microbiological quality and safety of cosmetic products. There are several areas of the water treatment process where such failures may occur. They can be technical system failures - particularly failures in the efficacy of antimicrobial system elements. But they may also result from inadequate adherence to specifications for procedures, implementation of measures (e.g. disinfection, maintenance) and control testing (sampling, methods). In order to avoid errors, it is essential that all processes, measures and equipment are properly defined and monitored. Detection of defects and errors requires immediate root cause analysis, risk assessment and appropriate corrective actions. Water treatment and use processes should be integrated into the microbiological quality management (MQM) system to ensure compliance with specifications and process definitions, error detection and corrective actions.
