Natural surfactants used in cosmetics : glycolipids / Nattaya Lourith in INTERNATIONAL JOURNAL OF COSMETIC SCIENCE, Vol. 31, N° 4 (08/2009)
[article]
Titre : Natural surfactants used in cosmetics : glycolipids Type de document : texte imprimé Auteurs : Nattaya Lourith, Auteur ; M. Kanlayavattanakul, Auteur Année de publication : 2009 Article en page(s) : p. 255-261 Note générale : Bibliogr. Langues : Anglais (eng) Tags : Biosurfactant Cosmétiques Mannosylérythritol lipides Rhamnolipides Sophorolipides Index. décimale : 668.5 Parfums et cosmétiques Résumé : Cosmetic surfactant performs detergency, wetting, emulsifying, solubilizing, dispersing and foaming effects. Adverse reactions of chemical synthesis surfactant have an effect on environment and humans, particularly severe in long term. Biodegradability, low toxicity and ecological acceptability which are the benefits of naturally derived surfactant that promises cosmetic safety are, therefore, highly on demand. Biosurfactant producible from microorganisms exhibiting potential surface properties suitable for cosmetic applications especially incorporate with their biological activities. Sophorolipids, rhamnolipids and mannosylerythritol lipids are the most widely used glycolipids biosurfactant in cosmetics. Literatures and patents relevant to these three glycolipids reviewed were emphasizing on the cosmetic applications including personal care products presenting the cosmetic efficiency, efficacy and economy benefits of glycolipids biosurfactant.

Titre : Study of glycerol and sweet water as a carbon source for production of ramnolipids by naturally occurring strains of pseudomonas aeruginosa (ATCC 10145 and ATCC 9027) Type de document : texte imprimé Auteurs : S. Wadekar, Auteur ; S. Patil, Auteur ; A. M. Lali, Auteur ; D. N. Bhowmick, Auteur ; Ashish Pratap Singh, Auteur Année de publication : 2010 Article en page(s) : p. 238-241 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Surfactants Tags : Surfactant Rhamnolipides 'Pseudomonas aeruginosa' 'Croissance bactérienne' Glycérol 'Traitement différé' Optimisation Index. décimale : 668.1 Agents tensioactifs : savons, détergents Résumé : The interest in biosurfactant has increased considerably due to their large potential for industrial applications. Rhamnolipid is a simplest class of biosurfactants with well defined structure. The main obstacle in commercialization of biosurfactant especially rhamnolipids is the higher cost of the production. Glycerol is readily available from commercial fat-splitting process in the form of sweet water (up to 20% w/v) at very low cost. Two natural strains of Pseudomonas aeruginosa (ATCC 10145 and ATCC 9027) were compared for rhamnolipid production. The neotype strain of Pseudomonas aeruginosa (ATCC 10145) was found to produce more amounts of rhamnolipids than Pseudomonas aeruginosa (ATCC 9027) on glucose and glycerol as carbon source. The microbial growth (0.94 g/L) and formation of rhamnolipids (2.75 g/L) was maximum at 5% (w/v) glycerol concentration by Pseudomonas aeruginosa (ATCC 10145). The fermentation was monitored for 8 days on shake flask and magnetically stirred batch culture. In magnetically stirred batch culture, microbial growth was 0.69 g/L and 2.73 g/L of rhamnolipid was formed. Sweet water was also used as a source of glycerol.
