Langues : Anglais (eng) Catégories : Bactéries -- Identification Contamination microbienne Cosmétiques -- Aspect sanitaire Evaluation Microbiologie Index. décimale : 668.5 Parfums et cosmétiques Résumé : Aerobic spore-formers of the genus Bacillus are found as contaminants of cosmetic products. Therefore, the primary target is to avoid contaminations with these microorganisms. For this purpose, requirements are needed for raw materials-quality as well as for the hygiene-system in the production areas. Additionally, growth of these contaminants has to be avoided through an effective preservation of product-phases and the finished product. Usual preservative systems can be assumed to be effective against these spore-formers. Cosmetic products containing -counts in conformity with the limits given in ISO 17516 do not present a risk for the product or the health of the user. This applies for products used under usual conditions, and if the microorganisms are not able to multiply in the product and if the conformity of the batch with the required microbiological limits is proven in adequate control tests.

Application of a Microbiological Quality Management (MQM) for Cosmetics / Ulrich Eigener in SOFW JOURNAL, Vol. 131, N° 6 (06/2005)

[article]  inSOFW JOURNAL > Vol. 131, N° 6 (06/2005) . - p. 2-11 Titre : Application of a Microbiological Quality Management (MQM) for Cosmetics Type de document : texte imprimé Auteurs : Ulrich Eigener, Auteur Année de publication : 2005 Article en page(s) : p. 2-11 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Cosmétiques -- Aspect sanitaire Cosmétiques -- Législation Tests microbiologiques Index. décimale : 668.5 Parfums et cosmétiques Résumé : Ensuring an appropriate microbiological quality of cosmetics repeatedly causes various problems in the daily business as documented in numerous publications since the sixties (Eigener, 1995). On the other hand, cosmetic products of reliable quality and safety which do not pose any risk to the user are a world-wide legal requirement. In this connection the consumers' safety has been emphasized by the 6th Amendment of the EC Cosmetics Directive of 1993 (93/35/EWG), which introduced a safety assessment for cosmetics. This includes aspects of microbiological product safety (Eigener, 1994a). To reliably obtain a microbiological quality as demanded by law but also for the benefit of the cosmetic supplier it is not sufficient to perform selected microbiological checks, which might by chance indicate compliance to given requirements. The aim must be to apply state of the art techniques; that means: reliable quality can only be achieved in a system approach. The desired quality must be obtained through a process a development and manufacture under control by means of appropriate requirements and checks. All microbiological activities in this connection are collected under the term of microbiological quality management (MQM).

Complaints correctly employed for microbiologically safe cosmetic products / Ulrich Eigener in SOFW JOURNAL, Vol. 148, N° 1/2 (01-02/2022)  

[article]  inSOFW JOURNAL > Vol. 148, N° 1/2 (01-02/2022) . - p. 40-45 Titre : Complaints correctly employed for microbiologically safe cosmetic products Type de document : texte imprimé Auteurs : Ulrich Eigener, Auteur Année de publication : 2022 Article en page(s) : p. 40-45 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Analyse des défaillances (fiabilité) Contamination microbienne Cosmétiques -- Aspect sanitaire Risques microbiologiques Sécurité des produits de consommation Index. décimale : 668.5 Parfums et cosmétiques Résumé : Through regularly testing complaint samples for the microbial count, a market surveillance can be performed, which can serve for controlling of all measures applied for reaching the microbiological safety of the cosmetic products. If counts which exceed given limits are detected, processes in development and production have to be checked and further chemical and microbiological testing has to be applied in course of the essential root cause analysis. A risk assessment must be performed and decisions for follow up-actions (corrections and corrective actions) have to be made, which must then be carefully implemented. In this way detected failures will lead to improvements of product and quality system. Such approach has a special importance for the valid application of the preservative efficacy test (PET) and its significance for the microbiological product safety. On the other hand, microbiological findings from the complaint samples which are in conformity with the given limit counts indicate the sufficient efficacy of system measures to reach the microbiological product safety.

Evaluation of health risks caused by microorganisms in cosmetic products / Ulrich Eigener in SOFW JOURNAL, Vol. 146, N° 12 (12/2020)  

[article]  inSOFW JOURNAL > Vol. 146, N° 12 (12/2020) . - p. 24-28 Titre : Evaluation of health risks caused by microorganisms in cosmetic products Type de document : texte imprimé Auteurs : Ulrich Eigener, Auteur ; Joelle Nussbaum, Auteur ; Rainer Simmering, Auteur Année de publication : 2020 Article en page(s) : p. 24-28 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Contamination microbienne Cosmétiques Cosmétiques -- Aspect sanitaire Evaluation du risque Risques pour la santé Index. décimale : 668.5 Parfums et cosmétiques Résumé : Microbial contamination of cosmetic products may under certain conditions lead to a health risk of the consumer. Such health hazards obviously appear very rarely if the consumers are in good health and consequently there are no reports of such cases. However, due to the pathogenic character of some microorganisms found as contaminants in cosmetic products, health hazards cannot be excluded and have also been demonstrated in predisposed users. Therefore, microbiologically safe products must guarantee not to cause a health risk for the user. The requirement for sufficiently safe microbial counts can only be fulfilled through a suitable formulation providing an efficient preservation, through a safe manufacturing process and the application of adequate control measures. These targets require all personnel to act responsibly in each process area involved. Respective effective procedures and measures demand a quality management system (based on MQM), which also ensures the qualified performance of microbiological activities including professionally made decisions and risk assessments.

Impact of specified microorganisms on quality and safety of cosmetic products / Ulrich Eigener in SOFW JOURNAL, Vol. 148, N° 11 (11/2022)  

[article]  inSOFW JOURNAL > Vol. 148, N° 11 (11/2022) . - p. 32-35 Titre : Impact of specified microorganisms on quality and safety of cosmetic products Type de document : texte imprimé Auteurs : Ulrich Eigener, Auteur Année de publication : 2022 Article en page(s) : p. 32-35 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Contamination microbienne Cosmétiques -- Analyse Cosmétiques -- Aspect sanitaire Microorganismes Risques microbiologiques Risques pour la santé Sécurité des produits de consommation Spécifications Tests microbiologiques Index. décimale : 668.5 Parfums et cosmétiques Résumé : “Specified microorganisms“ are used as a separate group when defining limit counts for cosmetic products (e.g., ISO 17516). Usually, there are four species of microorganisms assigned to this specification group. It has, however, been known for a long time that more than these mentioned species might be of relevance as health hazards for the product user and also for causing alterations of the product characteristics. To reliably reach product quality and safety targets for the product, it is recommended to increase the above-mentioned specification-group in a product-related way through further relevant microorganisms. The species explicitly mentioned in the given norms should therefore be understood as “examples” and not as “exclusive”. To select further species to be assigned to the “specified microorganisms”, detected contaminants should be identified and assessed, or microorganism should be chosen according to experience or literature data. It is essential that species detected and classed as “specified microorganisms” are also sufficiently taken into consideration when defining procedures, measures and examinations as components of the quality management system (e.g., requirements for raw materials, examination methods for control purposes and spectrum of test organisms for preservation efficacy tests).
