Effect of foaming method on mechanical properties of aqueous foams prepared from surfactant solution / Masayuki Yamaguchi in Industrial & engineering chemistry research, Vol. 51 N° 44 (Novembre 2012) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 51 N° 44 (Novembre 2012) . - pp. 14408-14413 Titre : Effect of foaming method on mechanical properties of aqueous foams prepared from surfactant solution Type de document : texte imprimé Auteurs : Masayuki Yamaguchi, Auteur ; Chiyo Kanoh, Auteur ; Jiraporn Seemork, Auteur Année de publication : 2013 Article en page(s) : pp. 14408-14413 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : Surfactant  Foam  Mechanical  properties  Foaming Résumé : The effect of foaming methods on the linear and nonlinear rheological properties is studied employing foams prepared from aqueous solutions of sodium laurate. It is found that the liquid-phase fraction of the foam prepared by a foaming net is significantly lower than that by a conventional mixer. Consequently, the foaming net provides a stable foam that hardly shows drainage. Moreover, the foam by the foaming net shows low storage modulus, whereas it exhibits high yield stress. As a result, it behaves as an elastic body in the wide range of the strain. Considering that aqueous foams such as facial cleansing are usually prepared by a foaming net, much attention has to be paid to the foaming method.
