The present invention generally relates to improved aerated compositions comprising stabilized colloidal or colloidal--like phases (e.g., emulsions, aphrons) and methods of using those compositions. The compositions generally comprise an oleaginous bulk phase, an aqueous minor phase one or more surfactants, aphrons and one or more aphron stabilizers. The compositions of the present invention are stable, having increased half-lifes and are capable of being used in high pressure applications.
La présente invention se rapporte d'une manière générale à des compositions aérées améliorées qui comprennent des phases stabilisées colloïdales ou de type colloïdal (p.ex., des émulsions, des aphrons) et des procédés d'utilisation de ces compositions. Les compositions comprennent d'une manière générale une phase oléagineuse en vrac, une phase aqueuse mineure, un ou plusieurs surfactants, des aphrons et un ou plusieurs stabilisateurs d'aphrons. Les compositions de la présente invention sont stables, ont une plus grande durée de conservation et peuvent s'utiliser dans des applications à haute pression.
