Organoclay compositions which comprise the reaction product of a smectite-type clay having an ion exchange capacity of at least 50 meq. wt. per 100 g. clay (active basis), and a branched chain quaternary ammmonium compound are useful self-activating and self-dispersing additives to liquid organic systems such as grease and ink formulations. Also included are grease and ink formulations using these organoclay compositions.
La présente invention concerne des compositions d'argile organique comprenant le produit de réaction d'une argile du type smectite dont la capacité d'échange ionique est d'au moins 50 méq. en poids pour 100 gr d'argile (base active) et un composé ammonium quaternaire à chaînes ramifiées, lesquels constituent des additifs auto-activants et auto-dispersants utiles des systèmes organiques liquides tels que les formulations de graisses et d'encres. L'invention concerne également des formulations de graisses et d'encres utilisant ces compositions d'argile organique.
