Surfactant Testing
Surfactant testing plays a crucial role in ensuring product performance and safety. By testing the composition, content, and performance characteristics of surfactants, product formulations can be optimized, enhancing product quality and innovation. For example, testing the foam, emulsification, and dispersion properties of surfactants can assess their effectiveness in various application scenarios. In addition, surfactant testing also includes the analysis of their physicochemical properties, such as cloud point, critical micelle concentration (CMC), and surface tension. These indicators directly affect the product's performance and stability.

Emulsification Performance Testing
Analyzes emulsion droplet size distribution, emulsification stability, and phase separation to improve the uniformity and storage stability of emulsions.
Wetting Performance Testing
Evaluates the wetting performance of surfactants on different materials, optimizing their application in textiles, coatings, and adhesives.
Dispersion Performance Testing
Tests the stability of surfactants in suspension systems, helping to improve product uniformity and dispersion efficiency.
Critical Micelle Concentration (CMC) Measurement
Accurately measures the CMC of surfactants to help determine the optimal usage concentration and optimize formulation performance.
Solubility Testing
Solubility testing evaluates the dissolution capacity of surfactants in different solvents. Common methods include conductivity measurement and solubility testing.
Adsorption Performance Testing
Measures the adsorption amount of surfactants on solid surfaces to evaluate their performance. Common methods include specific surface area analysis and adsorption capacity testing.
Thermal Stability Testing
Thermal stability testing evaluates the stability of surfactants under high-temperature conditions. Common methods include heat treatment and differential scanning calorimetry (DSC).
Biodegradability Testing
Biodegradability testing assesses the environmental friendliness of surfactants by measuring their degradation rate in biological environments.
Chemical Analysis
Chemical analysis determines the chemical composition and structure of surfactants. Common methods include infrared spectroscopy (IR), ultraviolet-visible spectroscopy (UV-Vis), mass spectrometry (MS), and nuclear magnetic resonance (NMR).
What Types of Surfactants Can We Test?
Anionic Surfactants
We provide testing for anionic surfactants, which are widely used for their excellent cleaning, emulsifying, and foaming properties. Common examples include sodium lauryl sulfate and linear alkylbenzene sulfonates.
Cationic Surfactants
Our laboratory also offers testing for cationic surfactants, known for their strong conditioning, antimicrobial, and antistatic properties. Examples include quaternary ammonium compounds like cetyltrimethylammonium bromide (CTAB).
Nonionic Surfactants
We test nonionic surfactants, which are prized for their mildness, low toxicity, and excellent solubility. Examples include polyethylene glycol (PEG) esters and alkyl polyglucosides.
Amphoteric Surfactants
Our testing services extend to amphoteric surfactants, which exhibit both positive and negative charges depending on the pH. These are often used in personal care products and are gentle on the skin. Examples include betaines and amino acid-based surfactants.

Surfactant Characterization Tailored to Your Needs
Alfa Chemistry designs and implements personalized testing programs based on the specific needs of our clients. Whether it is tailored for particular application scenarios (such as high-end skincare products or industrial cleaning agents) or meeting specific technical requirements (such as low-temperature emulsification efficiency or high wetting performance), Alfa Chemistry can provide customized solutions. For example, some companies require efficient emulsification at low temperatures while minimizing by-product formation. Alfa Chemistry can meet these needs by adjusting formulations and technical methods.
Surfactant Analysis Techniques
Alfa Chemistry Testing Lab offers a wide range of surfactant characterization testing techniques, utilizing various methods and instruments to comprehensively evaluate the chemical properties, physical performance, and functional behavior of surfactants in different applications.
Fourier Transform Infrared Spectroscopy (FTIR) Analysis
FTIR is a commonly used characterization technique for analyzing the molecular structure of surfactants. Our laboratory employs a Nicolet iS50 FTIR spectrometer to analyze samples, providing structural information based on the position and intensity of absorption peaks. This enables precise identification of chemical bonds and functional groups within the surfactant molecules.
High-Performance Liquid Chromatography (HPLC) and Liquid Chromatography-Mass Spectrometry (LC-MS)
HPLC and LC-MS are employed to separate and identify the components of surfactants. Our lab is equipped with an Agilent 1260 Infinity LC system and a ZORBAX C18 column, combined with a 6250 Accurate-Mass Q-TOF/MS mass spectrometer for analysis. This setup provides high-precision mass information, enabling accurate determination of surfactant composition and molecular weight.
Ultraviolet-Visible Spectroscopy (UV-Vis) Analysis
UV-Vis spectroscopy is used to analyze the absorption characteristics of surfactants, particularly in studies related to bioactivity. Our lab uses a Hewlett Packard 8453 spectrophotometer to provide detailed insights into the molecular structure and functional groups of surfactants through their UV-Vis absorption spectra.
Cryogenic Transmission Electron Microscopy (cryo-TEM)
Cryo-TEM is employed to observe the molecular structure and self-assembly behavior of surfactants at the nanoscale. Our laboratory uses a Hitachi H-7000 microscope to perform rapid freezing and imaging of samples under liquid nitrogen conditions, allowing us to obtain high-resolution images of surfactant aggregates and micelle formations.
