Abstract
The present invention relates to dispersants containing at least two lipophilic groups (e.g., alkenyl-substituted acylating agent, such as, dodecyl succinic anhydride), and the dispersants contain a hydrophilic component (e.g., alkylene glycol, polyalkylene glycol) present in an amount sufficient to at least partially disperse the amphiphilic compound in aqueous media (e.g., 30 wt % to 80 wt %). The invention further provides for dispersants as phosphate, sulphonate, and phosphite derivatives thereof. The invention further provides for the use of the dispersants in tinter compositions (e.g., universal tinter) and reduced shade paints.
