When formulating liquid aqueous detergent compositions containing bleaching substances, consider the issue of bleach instability. We note that problems sometimes arise. Although it is still not fully understood , this instability is caused by the dissolution of bleaching substances in the aqueous phase and subsequent decomposition of the dissolved bleaching substances. It is thought that this is caused by

Letchworth 1980. In general, the order of such systems is The extent in the primary chamber increases with increasing surfactant and/or electrolyte concentration. Non Always at low concentrations, surfactants exist as a molecular solution or as a solution of spherical micelles. However, both of these are isotropic. Further surfactants and/or electrolysis can be added to form a structured (ash isotropic) system.

They are rod micelles, planar lamellar structures, lamellar droplets, and liquid crystals, respectively. It is called by various terms such as crystal phase. Often, the same structure is actually Researchers have used a variety of terms. For example, in European Patent Application No. 151.884 , the lamellar droplets are called “spherulites”. Presence and confirmation of surfactant structured systems in liquids The identification may be performed by methods known to those skilled in the art, such as optical techniques, various flow measurements, Measured by radiation or neutron diffraction, and sometimes by electron microscopy. The composition is In many cases, the aqueous dispersion medium contains the dissolved electrolyte. It is preferable to contain. As used herein, the term electrolyte refers to any means an ionic water-soluble substance. However, in lamellar dispersions, all electrolysis The electrolyte does not necessarily dissolve, but the total electrolyte concentration of the liquid Because it is above the solubility limit, it is suspended as solid particles. The mixture of electrolytes is one or more electrolytes present in the dissolved aqueous phase and substantially suspended in the solid phase; It may also be used with one or more electrolytes present. two or more of electrolyte may be distributed more or less proportionally between these two phases. Partially, this This depends on processing, eg, the order of addition of ingredients. On the other hand, the term “salt” It does not matter whether they are ionic or not (surfactants and substances that can be contained outside the water) The term includes all organic and inorganic components of electrolytes (water-soluble quality).

Types of surfactants and their characteristics to produce stable liquids with the required structure The selection of sex is well within the ability of those skilled in the art. However, important subcategories Useful compositions of surfactants also include mixtures of surfactants differing in detergent activity. It can be said that Common mixtures useful in textile cleaning compositions include If the surfactant is non-ionic and/or non-alkoxylated anionic and/or alkaline Examples include those containing coxylated anionic surfactants.
