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).

1,2-Pentanediol - a multifuntional ingredient for personal care applications / Ravi Pillai in SOFW JOURNAL, Vol. 131, N° 6 (06/2005)

[article]  inSOFW JOURNAL > Vol. 131, N° 6 (06/2005) . - p. 12-22 Titre : 1,2-Pentanediol - a multifuntional ingredient for personal care applications Type de document : texte imprimé Auteurs : Ravi Pillai, Auteur ; G. Schmaus, Auteur ; S. Lange, Auteur ; J. Roeding, Auteur Année de publication : 2005 Article en page(s) : p. 12-22 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Antimicrobiens Cosmétiques -- Additifs Emulsions -- Emploi en cosmétologie Formulation (Génie chimique) Matériaux -- Propriétés fonctionnelles Peau -- Soins et hygiène Pentylène glycol Le pentane-1,2-diol est un alcool de formule brute C5H12O2. C'est une molécule chirale car l'atome de carbone 2 portant un hydroxyle est asymétrique. Le pentane-1,2-diol se présente donc sous la forme de deux énantiomères : le R-pentane-1,2-diol et le S-pentane-1,2-diol. Produits hydratants Résistance à l'humidité:Résistance à l'eau Index. décimale : 668.5 Parfums et cosmétiques Résumé : 1,2-Pentanediol (INCI: Pentylene Glycol, trade name: Hydrolite-5) is a widely used cosmetic raw material with multifunctional properties. It is an excellent moisturizing ingredient for topical preparations. Besides it has very good antimicrobial and solubilizing properties. It also improves the water resistance of sunscreen formulations. This paper discusses the studies that exemplify the multifunctional aspects of 1,2-Pentanediol. It also discusses the results of a new study, which looks at the effect of 1,2-Pentanediol on the particle size and particle size distribution of an oil-in-water emulsion. The new study shows that 1,2-Pentanediol is able to significantly reduce the particle size of cosmetic emulsions. Furthermore, sensory studies with emulsions containing 1,2-Pentanediol demonstrated that the appearance and the tactile properties of cosmetic emulsions are also improved by the addition of this multifunctional ingredient.

Low foaming surfactant systems for industrial applications / B. Jakobs in SOFW JOURNAL, Vol. 131, N° 6 (06/2005)

[article]  inSOFW JOURNAL > Vol. 131, N° 6 (06/2005) . - p. 63-68 Titre : Low foaming surfactant systems for industrial applications Type de document : texte imprimé Auteurs : B. Jakobs, Auteur ; B. Breitzke, Auteur ; M. Stolz, Auteur ; R. Verzellino, Auteur Année de publication : 2005 Article en page(s) : p. 63-68 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Alcoxylates Détergents Diagrammes de phases Mouillage (chimie des surfaces) Mousse (chimie) Surfactants Index. décimale : 668.1 Agents tensioactifs : savons, détergents Résumé : In many applications the surfactant system has to meet contradicting physical requirements. The surfactants should provide not only excellent cleaning performance but additionally exhibit low foaming properties. However, the same physical parameters that need to be adjusted to ensure effective wetting power are on the other hand responsible for the effective formation and stabilization of foam. A good basis for a deeper understanding of foaming behavior offer phase behavior studies. In the case of alcohol ethoxylates a lot of those studies exist and the connection between the water solubility, the cloud point phenomena and the foaming behavior is generally recognized. However, the situation is more complex in the case of the alcohol EO-PO adducts, which are empirically recognized as low foaming agents. Up to now there is no coherent set of physico-chemical studies to provide a basic understanding of the low foaming behavior. This presentation gives some insight into the principles lying behind the foaming action of surfactants and compares the physico-chemical characteristics of alcohol ethoxylates and EO-PO adducts. The results can give the formulator guidance for selecting low foaming surfactant for more demanding applications. Note de contenu : - Application properties - Defoaming mechanism - FIGURES : 1.
