The common used thickening and suspending stabilizing agents available in today’s market are reviewed.
The thickening agents include:
(a) CLAY MINERALS, such as Magnesium aluminium silicate, attapulgite, bentonite, hectorite and sepiolite;
(b) ORGANIC thickening agents, such as Cellulose ethers and acrylic thickeners
The theories of mechanisms of thickening are presented as well as the causes of thixotropic and pseudoplastic behaviour.
The strong and weak points of covered rheological agents are discussed.
