In 15 chapters it supports formulation chemists in preparing a suspension in a more rational way, by applying the principles of colloid and interface science, while at the same time enabling the research scientist to discover new methods for preparing stable suspensions. Essential reading for those working in the pharmaceutical, cosmetic, food, paint, ceramic and agricultural industries. 606 $aColloids 606 $aPolymers 606 $aPigments 606 $aDispersion 615 0$aColloids. 615 0$aPolymers. 615 0$aPigments. 615 0$aDispersion. 676 $a500 676 $a541.34 676 $a600 702 $aTadros$b Tharwat F.$f1937- 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910810629103321 996 $aDispersion of powders in liquids and stabilization of suspensions$94077204 997 $aUNINA
