CAS 9002-92-0 identifies polyoxyethylene lauryl ether, an ethoxylated fatty alcohol and nonionic surfactant. I generally describe it as a product family rather than a perfectly uniform single molecule, because commercial grades may contain a distribution of ethylene oxide chain lengths. A representative grade is often associated with Laureth-4 or Brij-type chemistry, with approximately 4 ethylene oxide units and a nominal molecular mass near 362.6 g/mol for the idealized structure. Its main industrial value is surface activity: it can help wet, emulsify, solubilize, disperse, and stabilize ingredients in water-based and mixed-phase formulations.
CAS 9002-92-0 belongs to the alcohol and ether surfactant category. Chemically, it contains a lauryl-derived hydrophobic chain and a hydrophilic polyoxyethylene segment. This dual structure allows the material to position itself at interfaces, such as oil-water or air-water boundaries, where it can reduce interfacial tension and support more uniform processing.
The CAS number is useful for identification, but it does not by itself define every commercial specification. The actual performance can depend on average ethoxylation, raw material distribution, water content, free alcohol, color, and the supplier’s quality limits. For that reason, I recommend evaluating the CAS number together with the product specification, technical data sheet, safety data sheet, and application requirements.
CAS 9002-92-0 can improve contact between a liquid and a solid surface by helping the formulation spread more evenly. This function is relevant when powders, pigments, fibers, or other substrates are difficult to wet. The required dosage is formulation-dependent, so I treat a laboratory screening range such as 1–10 wt% as an initial evaluation window rather than a universal recommended level.
As a nonionic surfactant, it may help combine or stabilize components that otherwise separate, particularly in systems containing oils, waxes, fragrances, or hydrophobic additives. Its performance depends on the oil phase, temperature, electrolyte concentration, pH, and the presence of co-surfactants. A successful formulation should therefore be confirmed through stability testing rather than selected from the CAS number alone.
The material can support the distribution of fine ingredients and may improve consistency during mixing. It is not automatically a complete dispersant package for every pigment or mineral system. In demanding applications, I normally assess it alongside rheology modifiers, protective colloids, defoamers, and other surfactants.
Manufacturers may consider CAS 9002-92-0 for industrial and formulated products that require nonionic surface activity. Potential areas include cleaners, emulsions, textile auxiliaries, coatings, agricultural formulations, personal-care products, and general process formulations. Whether it is suitable depends on the required regulatory status, purity, odor, color, foam profile, compatibility, and end-use exposure conditions.
The most important distinction is the average number of ethylene oxide units. A lower ethoxylation level generally produces a more oil-compatible material, while a higher level usually increases hydrophilicity; however, the exact behavior depends on the complete molecular distribution. CAS 9002-92-0 is therefore best purchased by matching a defined commercial grade rather than assuming that all suppliers offer identical material.
In procurement, I may compare options by appearance, active content, water content, acid value, hydroxyl value, color, cloud point, HLB information, viscosity, and packaging condition. Not every supplier uses the same test method, and some values may be reported as typical rather than guaranteed. Buyers should request the current specification and confirm whether each parameter is a release limit or an indicative value.
| Specification area | Why it matters | What I recommend confirming |
|---|---|---|
| Identity | Confirms the intended chemical family | CAS 9002-92-0, product name, INCI or industry synonym where applicable |
| Ethoxylation profile | Influences water compatibility and emulsification | Average EO level or supplier-defined grade description |
| Appearance | Supports batch consistency and visual quality | Color, physical form, odor, and test temperature |
| Performance indicators | Helps predict formulation behavior | HLB, cloud point, viscosity, water dispersibility, and foam tendency |
| Quality and logistics | Reduces receiving and production risk | COA format, batch traceability, packaging, shelf-life guidance, and transport conditions |
For a representative Laureth-4-type structure, the nominal molecular mass is approximately 362.6 g/mol, but this should not be treated as the exact molecular mass of every commercial lot. Commercial ethoxylates are commonly distributed mixtures, so average values are more meaningful than a single structural formula. I also advise buyers to check whether the supplier’s cloud point or HLB value applies to the exact grade and test method being offered.
Yuking are exported all over the world and different industries with quality first. Our belief is to provide our customers with more and better high value-added products. Let's create a better future together.
First, define whether the material is needed primarily for wetting, emulsification, solubilization, detergency, or dispersion. These objectives can require different balances of hydrophilicity, oil affinity, foam, and temperature response. I then identify the other surfactants, solvents, salts, polymers, pigments, and active ingredients that may change performance.
Temperature is important because viscosity, phase behavior, and cloud-point response may change during storage and processing. A practical storage discussion often begins around 5–35°C, but the supplier’s handling guidance should control because the physical state can vary by grade. Buyers should also test the product under the actual process temperature, shear rate, dilution ratio, and water hardness used in production.
I recommend requesting a technical data sheet, safety data sheet, certificate of analysis, packaging details, and a sample from the intended production grade. The COA should identify the batch and show the agreed test results, while the TDS should clearly separate typical data from guaranteed limits. For regulated or consumer-facing applications, the buyer should independently verify market-specific compliance before commercial use.
Price alone is not a reliable selection criterion for CAS 9002-92-0. A lower quoted price may be offset by differences in active content, water content, packaging, minimum order quantity, lead time, or batch consistency. I suggest comparing suppliers on total delivered cost, documentation quality, technical response time, and the ability to maintain the same grade over repeat orders.
Before placing a purchase order, confirm the packaging unit, net weight, pallet configuration, delivery location, payment terms, and required documents. Also ask how the supplier manages changes in raw materials or production sites. These checks are especially important when the surfactant is used in a validated formulation or a process with narrow quality tolerances.
At Yuking, we support B2B buyers by helping clarify the difference between the CAS identity and the actual commercial grade. We can discuss the intended application, required physical form, specification priorities, packaging, and export documentation before quotation. This approach helps buyers avoid selecting a material based only on a familiar synonym or a nominal ethoxylation number.
For a project evaluation, I recommend starting with the target application, expected annual demand, destination market, and required quality parameters. Yuking can then help organize the technical information needed for sample assessment and supplier comparison. Availability, MOQ, lead time, and final specifications should be confirmed for the current order because they depend on grade and destination.
CAS 9002-92-0 can be a useful nonionic surfactant when a formulation requires controlled wetting, emulsification, solubilization, or dispersion support. The right choice depends less on the CAS number alone and more on the ethoxylation profile, specification limits, process conditions, regulatory needs, and compatibility with the complete formulation. I recommend screening a defined supplier grade, testing it at the intended concentration and temperature, and reviewing batch documentation before approval.
