At very low concentrations, surfactants It can exist as a molecular solution or as a solution of spherical micelles, and these solutions The displacement is also isotropic. When additional surfactants and/or electrolytes are added, the structure Structured and anisotropic) systems can be produced. For such systems, “rod micelles” , various names such as “planar lamellar structure”, “lamellar droplet” and “liquid crystal phase” are given to each. often refer to structures that are actually the same thing However, different researchers used different words. For example, in the European Patent Application Publication In Japanese Patent Publication No. 151884, lamellar droplets are called "spherulites". Surface activity in liquids Confirming the presence of the agent structured system and identifying the chain threads can be done by means known to those skilled in the art. These known means include, for example, optical techniques, various flow rate measuring methods, These include line or neutron diffraction, and sometimes electron microscopy.

Ru. This solid is commonly used as a detergency builder, i.e. calcium ions and water hardeners in the wash solution. It exists to counteract the effects of The second product, the suspended facet, usually does not dissolve in the system. containing fine granular abrasives, present to contribute to the structuring of the active substance in the dispersed phase. The electrolyte used is usually different from the abrasive compound. However, in some cases, abrasives , may contain partially soluble salts that dissolve upon product dilution.

Amazingly, it can be added to bleach products without unduly affecting its stability. In addition, if we compare Example 16 with Example 15 (comparative example), , surprisingly when using a textile softening clay in combination with a bleaching agent It is clear that improved solids suspension properties can be achieved.
