Poorly soluble drugs in aqueous drug-delivery systems are prone to insufficient drug-loading concentrations, crystallization during storage, and precipitation after dilution with physiological fluids. Solubilizers, hydrotropes, and cosolvents can increase drug solubility through micellar ...
In laundry detergents, automatic dishwasher detergents, and hard-surface cleaners, many cleaning problems are not caused by surfactants completely failing to remove soils. Instead, the soils may be detached from the surface and enter the wash liquor, but they are not kept under stable control. ...
Surfactants are a class of molecules with an amphiphilic structure. They are typically composed of two parts: one end is a hydrophilic head group, which tends to interact with water; the other end is a hydrophobic chain segment, which tends to interact with oils, air, or nonpolar substances.
Sodium tripolyphosphate (STPP) is a classic phosphate-based builder used in household and industrial cleaning formulations. It is commonly found in laundry powders, powdered cleaners, and some industrial cleaning systems. The core value of sodium tripolyphosphate is that it improves the ...
The strongly acidic cleaning systems discussed in this article mainly refer to products such as toilet bowl cleaners, bathroom descalers, acidic rust removers, and acidic hard-surface cleaners. These products typically use acids such as hydrochloric acid, phosphoric acid, sulfuric acid, sulfamic ...
The “betaine” discussed in this article specifically refers to cocamidopropyl betaine, a widely used ingredient in daily chemical cleansing formulations. Its international abbreviation is CAPB, while in domestic supply channels it is also often abbreviated as CAB. This article focuses on ...
In household and personal-care cleaning products, “degreasing” does not simply mean dissolving oily soils. Instead, surfactants change the interfacial relationships among oil, water, and the surface being cleaned. As a result, oily soils originally attached to the surface can be wetted, ...
In water-based household and industrial cleaning formulations such as dishwashing liquids, hard-surface cleaners, laundry detergents, and concentrated cleaners, formulators often encounter issues that may appear different on the surface but are closely related in nature.
In the production of cleansing products such as shampoos, body washes, hand soaps, and dishwashing detergents, AES is one of the commonly used primary surfactants. During winter production, many factories encounter a practical problem: after AES arrives, it becomes thickened, forms lumps, cannot ...
In laundry detergents, automatic dishwasher detergents, and hard-surface cleaners, many cleaning problems are not caused by surfactants completely failing to remove soils. Instead, the soils may be detached from the surface and enter the wash liquor, but they are not kept under stable control. ...
In daily chemical cleaning formulations, both sodium metasilicate and sodium tripolyphosphate are builder components. Their function is not to replace surfactants, but to improve cleaning conditions and enhance the working efficiency of surfactants and the overall cleaning system. The main ...
In the household and daily chemical industry, the term “sulfonic acid” usually refers to linear alkylbenzene sulfonic acid (LABSA). It is a basic surfactant raw material commonly used in laundry powder, liquid laundry detergent, dishwashing liquid, hard-surface cleaners, and certain industrial ...
A surfactant (surfactant / surface-active agent) refers to a class of substances that reduce the surface tension of the solution/continuous phase in which they are dissolved, and/or reduce the interfacial tension with another phase. Therefore, they preferentially adsorb at gas–liquid or ...
