The Detergency of Surfactants —— Types of Detergents
The Detergency of Surfactants —— Types of Detergents The detergency of surfactants is a fundamental property that gives them the greatest practical use. It involves the daily life of thousands of households and is increasingly applied in various industries and industrial productions. This article systematically reviews the representative types, characteristics and application trends of anionic, non-ionic and zwitterionic surfactants in detergents. 1. Anionic Surfactants The main types of anionic surfactants used as detergents include fatty acid salts (soap), alkylbenzene sulfonates (ABS), alcohol sulfates (AS), alcohol ether sulfates (AES), α-olefin sulfonates (AOS), alcohol ether carboxylates (AEC) and fatty acid methyl ester sulfonates (MES). Among them, linear alkylbenzene sulfonate (LAS) is known as the main force of synthetic detergents due to its strong detergency and good biodegradability. [citation:5] Type Representative Features & Applications fatty acid saltsSoapRich raw materials, but poor hard water resistance. Alkylbenzene sulfonatesLASStrong detergency, high cost performance. fatty alcohol sulfatesAS (Sodium Lauryl Sulfate)Good foaming, used in dentifrices, shampoos [citation:2]. α-olefin sulfonatesAOSUsed in hand soaps, dishwashing liquids. 2. Non-ionic Surfactants Non-ionic surfactants have good detergency for oily soil, hard water resistance, and can optimize performance by adjusting EO number. Representatives include alcohol ethoxylates and alkyl polyglycosides (APG). APG is praised as...

Comprehensive Guide to Surfactant Theory – Clean Chemical
Surfactants are often called “industrial MSG” and play a core role in cleaning, cosmetics, textiles, and industrial processing. This article takes you deep into the microscopic world and basic theories of surfactants. 1. What are Surfactants? Surface Tension Surface tension is the contractile force per unit length on the surface of a liquid, measured in N/m. Simply put, it is the force that minimizes the surface area of a liquid. Surface Activity The property of reducing the surface tension of a solvent is called surface activity. Substances that can form micelles in aqueous solutions and possess wetting, emulsifying, foaming, and washing properties are called surfactants. 2. Molecular Structure: Amphiphilic Nature The unique feature of surfactant molecular structure is its “Amphiphilic” nature: Hydrophobic Group: Long-chain non-polar group (e.g., hydrocarbon chain), soluble in oil, insoluble in water. Hydrophilic Group: Water-soluble group, ensuring the molecule dissolves in water. 3. Micelles & Critical Micelle Concentration (CMC) When the surfactant concentration reaches a certain level, molecules associate to form aggregates called micelles. The lowest concentration at which micelles form is called the Critical Micelle Concentration (CMC). Significance： Washing efficiency increases dramatically at the CMC. Generally, detergent concentration should be above the CMC for optimal performance....

Comprehensive Guide to Amphoteric Surfactants – Clean Chemical
Amphoteric surfactants are unique molecules that contain both anionic hydrophilic groups (such as carboxyl, sulfonic, or phosphate groups) and cationic hydrophilic groups (such as amino or quaternary ammonium groups) within the same molecule. Their defining characteristic is their ability to both donate and accept protons. Application of Betaine Surfactants Key Characteristics Versatility: Excellent washing, dispersing, emulsifying, bactericidal, softening, and antistatic properties. Mildness: Low irritation, compatible with anionic/nonionic types, and resistant to acids, alkalis, and hard water. Applications: Fabric finishing, personal care products, metal corrosion inhibition, and oilfield chemicals. Two Main Types: Amino Acid vs. Betaine Currently, synthetic amphoteric surfactants are mainly divided into two categories based on the structure of their cationic part: Feature (Amino Acid Type) (Betaine Type) Cationic Structure Amine Salt Quaternary Ammonium Salt Isoelectric Point Precipitates easily No precipitation, remains soluble pH Sensitivity Significant change (avoid isoelectric point) Stable in Acid/Neutral/Alkaline 1. Amino Acid Type Characteristics: The properties change drastically with the pH of the medium. Alkaline Medium: Acts as an anionic surfactant (water-soluble). Acidic Medium: Acts as a cationic surfactant (water-soluble). Isoelectric Point: Charges balance out, hydrophilicity decreases, leading to precipitation. Application Note: Must be used at a pH away from the isoelectric point to be...

Comprehensive Guide to Sulfate Surfactants: From Chemical Structure to Formulation Applications
Comprehensive Guide to Sulfate Surfactants: From Structure to Application Zhengzhou Clean Chemical Co., Ltd. presents a deep dive into sulfate surfactants like Sodium Lauryl Sulfate (SLS) and Sodium Laureth Sulfate (SLES). With global production exceeding 5 million tons in 2025, these materials are the backbone of personal care formulations. 1. Representative Sulfate Surfactants In personal care formulations, the most commonly used sulfate surfactants are alkyl sulfates and alkyl ether sulfates derived from fatty alcohols. Typical representatives include Sodium Lauryl Sulfate (SLS), also known as Sodium Lauryl Sulfate (SDS), and Sodium Laureth Sulfate (SLES). The common feature of these surfactants is a hydrophilic head group with a sulfate ester group (–OSO₃⁻) connected to a hydrophobic hydrocarbon chain, but they differ in the number of polyoxyethylene (ethoxy) units and the cations** (such as Na⁺ vs. NH₄⁺). 1.1 Chemical structure and properties Table: Chemical names, structural formulas and molecular weights of some representative sulfate surfactants used in personal care.

SLES Concentration Differences: 70% vs 60% vs 55% As a leading supplier of specialty chemicals, we understand the importance of selecting the right surfactant concentration for your formulations. Sodium Laureth Sulfate (SLES) is one of the most widely used anionic surfactants in the personal care and cleaning industries. This detailed comparison will help you understand the key differences between SLES 70%, 60%, and 55% concentrations to optimize your product development. Understanding Sodium Laureth Sulfate (SLES) Sodium Laureth Sulfate (SLES) is an anionic surfactant derived from coconut oil or palm kernel oil. It’s known for its excellent foaming, cleansing, and emulsifying properties. The percentage values (70%, 60%, 55%) refer to the active content of SLES in the aqueous solution, with the remainder being water and sometimes small amounts of salts or impurities. Important Note: These percentages indicate active matter content, not purity. All concentrations contain water as the balance component.
