    RAPA: a novel in vitro method to evaluate anti-bacterial skin cleansing products

    INTERNATIONAL JOURNAL OF COSMETIC SCIENCE, Issue 2 2010
    S. A. Ansari
    Synopsis Development of efficacious anti-bacterial skin cleansing products has been limited by the availability of a pre-clinical (in vitro) method to predict clinical efficacy adequately. We report a simple and rapid method, designated as rapid agar plate assay (RAPA), that uses the bacteriological agar surface as a surrogate substrate for skin and combines elements of two widely used in vivo (clinical) methods (Agar Patch and Cup Scrub). To simulate the washing of the human hand or forearm skin with the test product, trypticase soy agar plates were directly washed with the test product and rinsed under running tap water. After air-drying the washed plates, test bacteria (Staphylococcus aureus or Escherichia coli) were applied and the plates were incubated at 37°C for 18,24 h. Using S. aureus as the test organism, anti-bacterial bar soap containing triclocarbanilide showed a strong linear relationship (R2 = 0.97) between bacterial dose and their per cent reduction. A similar dose-response relationship (R2 = 0.96) was observed for anti-bacterial liquid hand soap against E. coli. RAPA was able to distinguish between anti-bacterial products based on the nature and level of actives in them. In limited comparative tests, results obtained by RAPA were comparable with the results obtained by clinical agar patch and clinical cup scrub methods. In conclusion, RAPA provides a simple, rugged and reproducible in vitro method for testing the relative efficacy of anti-bacterial skin cleansing products with a likelihood of comparable clinical efficacy. Further testing is warranted to improve the clinical predictability of this method. Résumé Le développement des produits de nettoyage de peau antibactérienne efficace a été limité par la disponibilité d'une méthode (in vitro) préclinique pour prévoir en juste proportion l'efficacité clinique. Nous rapportons une méthode simple et rapide, indiquée comme analyse rapide de plat d'agar (RAPA) ce des utilisations la surface bactériologique d'agar comme substrat de remplacement pour la peau et combinons des éléments de deux méthodes (cliniques) in vivo employées couramment (correction d'agar et la tasse frottent). Pour simuler le lavage de la peau humaine de main ou d'avant-bras avec le produit d'essai, des plats de l'agar de soja de trypticase ont été directement lavés avec le produit d'essai et rincés sous l'eau du robinet courante. Après l'air séchant les plats lavés, les bactéries d'essai (S. doré Ou Escherichia coli) étaient appliquées et des plats ont été incubées au °C 37 pendant 18,24 heures. Utilisant S. doré Comme organization d'essai, le triclocarbanilide contenant du savon de barre antibactérienne a montré un rapport linéaire fort (R2 = 0.97) entre la dose bactérienne et leur réduction de pour cent. On a observé un rapport semblable de réponse à dose donnée (R2 = 0.96) pour le savon liquide antibactérien de main contre E. coli. RAPA pouvait distinguer les produits antibactériens basés sur la nature et le niveau des actives dans eux. Dans les essais comparatifs limités, résultats obtenus par RAPA étaient comparables aux résultats obtenus par la correction clinique d'agar et la tasse clinique frottent des méthodes, en conclusion, RAPA fournit à une méthode in vitro simple, raboteuse et reproductible pour examiner l'efficacité relative des produits de nettoyage de peau antibactérienne la probabilité de l'efficacité clinique comparable. Davantage d'essai est justifié pour améliorer la prévisibilité clinique de cette méthode. [source]

    Safety, effectiveness and comparability of professional skin cleansers

    JOURNAL DER DEUTSCHEN DERMATOLOGISCHEN GESELLSCHAFT, Issue 10 2010

    Summary Background: There are no widely-accepted methodical specifications with which to objectify cleansing effectiveness and skin compatibility of occuptional skin cleansing products in Europe. Therefore the German Social Insurance Agency (DGUV) initiated a study with the goal to evaluate such products in view of the potency and the safety of hand cleansers. A market analysis was a part of the project. Methodology: The product descriptions and safety data sheets of 120 products (5,20/manufacturer) of 11 manufacturers were evaluated between 02/2008 and 04/2008. Results: The manufacturers used mainly ingredients of low irritancy. The declaration of the applied ingredients was in the majority of the cases correctly labeled according to the INCI Declaration. Although there was documentation of skin tolerability for most products, the manufacturers used widely differing tests of skin compatibility. Evidences for cleansing effectiveness were not declared or have not been provided. One manufacturer even promised medical effects of its products. There was no uniform general classification of products making it difficult to identify characteristics of cleansers and choose between them. Conclusions: Presently, there are no commonly accepted criteria to classify products in view of cleansing effectiveness und skin compatibility. Generally accepted criteria and test methods are needed for the evaluation of hand cleansers in order to provide the possibility of transparency and comparability. [source]

    Development of sonic technology for the daily cleansing of the skin

    JOURNAL OF COSMETIC DERMATOLOGY, Issue 2 2006
    Robert E Akridge PhD
    Summary Even though many skin cleansing products are commercially available, the cleansing of the skin is dependent upon the user's diligence, compliance, and technique, which often results in inconsistent cleansing. When the skin is inadequately or excessively cleansed, the skin becomes compromised, sometimes leading to acute or chronic conditions that may require medical attention. A sonic skincare brush was developed to enhance and provide consistent skin cleansing while preventing the skin from becoming compromised. Utilizing a technology previously used to cleanse the oral cavity, the sonic skincare brush is optimized to work with the skin's own elasticity providing rapid oscillatory flexing of the infundibular opening. By oscillating at sonic speed the net result is the inelastic comedones become loosened and detached from the infundibular wall and are then cleared from the acroinfundibulum. Although additional clinical research into the various applications of sonic skin care technology is needed, utilization of sonic technology is now available for effectively and consistently cleansing the skin.

    Surfactants, skin cleansing protagonists

    JOURNAL OF THE EUROPEAN ACADEMY OF DERMATOLOGY & VENEREOLOGY, Issue 1 2010

    Abstract The correct choice of cosmetic products and cleansers is very important to improve skin hydration, to provide moisturizing benefits and to minimize cutaneous damage caused by surfactants. In fact, surfactants may damage protein structures and solubilize lipids. Soaps, defined as the alkali salts of fatty acids, are the oldest surfactants and are quite aggressive. Syndets (synthetic detergents) vary in composition and surfactant types (anionic, cationic, amphotheric, non-ionic). These new skin cleansing products also contain preservatives, fragrances, and sometimes emollients, humectants and skin nutrients. We present a revision of the literature and discuss recent findings regarding skin cleansers. [source]
