Mechanisms of Action, Formulation Screening, and Safety Evaluation of Solubilizers, Hydrotropes, and Cosolvents in Drug-Delivery Systems
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 ...
Dispersants, Anti-Redeposition Agents, and Scale-Control Materials in Household Cleaning Formulations: Mechanisms of Action, Selection Logic, and Representative Products
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. ...
Understanding the Four Classes of Surfactants Through Molecular Charge: Application Logic of Anionic, Cationic, Amphoteric and Zwitterionic, and Nonionic Surfactants in Personal Care and Home Care
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.
How Can Sodium Tripolyphosphate (STPP) Be Replaced? From Detergency Mechanisms to Formulation Choices for Low-Phosphorus/Phosphorus-Free Builder Systems
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 ...
How to Select Thickeners for Strongly Acidic Cleaning Systems: Comparison of Thickening Mechanisms and Application Considerations for Fatty Amine Ethoxylates
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 ...
Understanding CAPB from Its Structure: How Cocamidopropyl Betaine Improves Foam, Enhances Mildness, and Supports Thickening
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 ...
Degreasing Agents from a Molecular-Structure Perspective: How AEO, APG, and Related Surfactants Can Replace Nonylphenol Ethoxylates (NPE)
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, ...
How Sodium Cumenesulfonate Improves the Stability of Water-Based Cleaning Formulations: From Structure and Phase Behavior to Selection Criteria
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.
AES (Fatty Alcohol Polyoxyethylene Ether Sulfate) in Personal and Home-Care Cleansing Formulations: An Analysis of Structure, Performance, and Low-Temperature Flowability
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 ...
Dispersants, Anti-Redeposition Agents, and Scale-Control Materials in Household Cleaning Formulations: Mechanisms of Action, Selection Logic, and Representative Products
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. ...
Differences, Mechanisms of Action, and Selection of Sodium Metasilicate and Sodium Tripolyphosphate in Detergent and Cleaning Formulations
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 ...
Why LABSA (Sulfonic Acid) Is Commonly Used in Household Cleaning Formulations: Neutralization Mechanism, Detergency Action, and Formulation Application Points
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 Panoramic Guide to Surfactants: Definitions & Mechanisms, Key Metrics, Application Scenarios, and Selection Navigation (Tables 1–3)
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 ...
