Thixotropic clay aqueous suspensions containing long chain saturated fatty acid stabilizers

Abstract From the Canadian patent

The physical stability of liquid gel-like compositions based on montmorillonite, attapulgite, hectorite or other inorganic colloid-forming clay or other thixotropic thickener is greatly improved by incorporating in the composition small amounts, such as 0.1 or 0.2 weight percent of long chain fatty acids. The aqueous compositions containing inorganic builder salts and other functional inorganic salts chlorine bleach, bleach-stable, detergent thixotropic thickener and a fatty acid as a physical stabilizer exhibit a significant increase in apparent viscosity and remain stable against phase separation for an extended period of time. The thixotropic properties can be retained or improved using …
