With an objective to test its in vivo anti-inflammatory potential, we conducted a screening clinical bioassay using randomized analysis on sixteen panelists. An emulsion containing 0.02% of sea whip extract was applied to the volar forearm of subjects prior to or after an ethyl nicotinate challenge. Blood flow rate at the application site monitored using a laser doppler blood flowmeter served as a measure of inflammation induced by ethyl nicotinate. Upon post-challenge treatment, sea whip extract reduced blood flow by 35.04% against untreated control and also delayed the blood flow. More pronounced reduction in blood flow, as low as 59.50%, was noted upon pretreatment. This reduction was significant (p < 0.0095). Pretreatment caused not only a delay in onset of inflammation but also a reduction in the peak time of blood flow. This study further substantiates the previously reported in vitro anti-inflammatory effect of sea whip extract, demonstrating its activity in deep skin layers by affecting blood flow. The preventive application prior to induction of inflammation was more effective when compared to post-treatment.

Formulating, packaging, and marketing of natural cosmetic products / Nava Dayan / Hoboken [USA] : John Wiley & Sons (2011)

Titre : Formulating, packaging, and marketing of natural cosmetic products Type de document : texte imprimé Auteurs : Nava Dayan, Editeur scientifique ; Lambros Kromidas, Editeur scientifique Editeur : Hoboken [USA] : John Wiley & Sons Année de publication : 2011 Importance : XII-427 p. Présentation : ill. Format : 24 cm ISBN/ISSN/EAN : 978-0-470-48408-1 Prix : 136,51 E Note générale : Index - Bibliogr. Langues : Américain (ame) Catégories : Biocosmétiques Cosmétiques -- Emballages Formulation (Génie chimique) Marketing Index. décimale : 668.5 Parfums et cosmétiques Résumé : The use of natural ingredients and functional botanical compounds in cosmetic products is on the rise. According to industry estimates, sales of natural personal care products have exceeded $7 billion in recent years. Nonetheless, many misconceptions about natural products—for instance, what "green" and "organic" really mean—continue to exist within the industry. Formulating, Packaging, and Marketing of Natural Cosmetic Products addresses this confusion head-on, exploring and detailing the sources, processing, safety, efficacy, stability, and formulation aspects of natural compounds in cosmetic and personal care products. Designed to provide industry professionals and natural product development experts with the essential perspective and market information needed to develop truly "green" cosmetics, the book covers timely issues like biodegradable packaging and the potential microbial risks they present, the use of Nuclear Magnetic Resonance (NMR) to identify biomarkers, and chromatographic methods of analyzing natural products. A must-read for industry insiders, Formulating, Packaging, and Marketing of Natural Cosmetic Products provides the reader with basic tools and concepts to develop naturally derived formulas.
