What Is CAS 9002-92-0? Uses, Specifications, and Safety Information

CAS 9002-92-0 generally identifies a nonionic surfactant in the polyoxyethylene lauryl ether family, also described as an ethoxylated dodecyl alcohol or laureth-type material. I treat this CAS number as a product-family identifier rather than a complete commercial specification, because the degree of ethoxylation, physical form, and quality grade can vary by supplier. Buyers should therefore confirm the exact product name, average ethylene oxide content, specification sheet, SDS, and intended application before placing an order. At Yuking, we help customers match CAS 9002-92-0 to the required formulation and supply conditions.

Key Takeaways

• CAS 9002-92-0 is associated with a nonionic ethoxylated lauryl alcohol surfactant family.
• Its main functions include wetting, emulsification, detergency, solubilization, and formulation stabilization.
• Commercial properties depend strongly on ethoxylation level, purity, water content, and grade.
• Buyers should evaluate HLB, cloud point, pH, appearance, active content, packaging, and SDS information together.
• Handling should follow the supplier’s current SDS, with suitable eye, skin, and respiratory protection based on the actual product form.

What Is CAS 9002-92-0?

CAS 9002-92-0 is commonly used for polyoxyethylene lauryl ether, a nonionic surfactant produced by reacting lauryl alcohol with ethylene oxide. The molecule contains a hydrophobic lauryl chain and a hydrophilic polyoxyethylene chain, allowing it to interact with both oils and water. This amphiphilic structure explains why the material is used in cleaning products, industrial formulations, textile processing, and other applications requiring controlled surface activity.

The CAS number alone does not define every performance characteristic. Ethoxylation level can influence water solubility, detergency, cloud point, foam behavior, viscosity, and emulsification performance. For this reason, I recommend using the CAS number for identity screening, then using the technical data sheet and a representative sample for final product selection.

Names and Product Descriptions

Depending on the supplier or market, CAS 9002-92-0 may be described as polyoxyethylene lauryl ether, laureth, ethoxylated lauryl alcohol, or polyethylene glycol dodecyl ether. These names can refer to related grades, but they should not automatically be treated as interchangeable. A buyer should check the stated average EO number, active matter, appearance, and application grade before comparing quotations.

Core Functions and Common Uses

Wetting and Surface Tension Reduction

CAS 9002-92-0 can improve contact between aqueous formulations and solid surfaces by reducing interfacial tension. This is useful when a product must spread across fibers, powders, pigments, metal surfaces, or hard substrates. In practice, the required dosage depends on the formulation, application method, water hardness, temperature, and the presence of other surfactants.

Emulsification and Solubilization

As a nonionic surfactant, it can help disperse or emulsify oil-compatible ingredients in water-based systems. It may also support the solubilization of fragrances, oily additives, and other hydrophobic components. Performance is not determined by CAS identity alone; the hydrophilic-lipophilic balance, phase behavior, and compatibility with the complete formulation must be evaluated.

Cleaning and Detergency

Ethoxylated lauryl alcohol materials are used in detergents and industrial cleaners because their structure can assist with wetting, soil removal, and oily residue dispersion. They may be blended with anionic, amphoteric, or other nonionic surfactants to adjust foam, detergency, and formulation stability. The final cleaning result should be verified under the customer’s actual concentration, temperature, and water conditions.

Industrial and Processing Applications

Potential application areas include textile auxiliaries, agricultural formulations, metal cleaning, paper processing, coatings, and general industrial formulations. The suitable grade depends on whether the priority is rapid wetting, low foam, emulsification, dispersing, or compatibility with salts and solvents. I recommend application testing before scale-up, especially when the product will be used in a regulated or sensitive end market.

Types and Material Options

The most important product difference is usually the average number of ethylene oxide units. Lower-ethoxylated grades may show stronger oil affinity and different cloud-point behavior, while higher-ethoxylated grades are generally more water-compatible; however, these are broad formulation tendencies rather than a substitute for measured data. Product form can also vary from a liquid to a paste or wax-like material depending on composition and temperature.

Key Specifications Buyers Should Request

A reliable purchase specification should include more than the CAS number. I suggest requesting appearance, color, odor, active content, moisture or water content, pH of a defined solution, cloud point, viscosity, acid value, hydroxyl value, and the stated average ethoxylation level where applicable. Not every parameter is required for every application, so the specification should be linked to the customer’s performance needs.

You will get efficient and thoughtful service from Yuking.

Three practical data points deserve particular attention: pH should be reported with its test concentration and temperature, cloud point should be reported in degrees Celsius, and viscosity should be reported in a stated unit such as mPa·s at a defined temperature. For example, “pH 6.0” without test conditions is incomplete, just as “viscosity 500” without the unit or temperature cannot support a meaningful comparison. I do not recommend treating an unqualified numerical value as a verified specification.

Packaging and Storage Information

Packaging may include drums, IBCs, or other bulk formats depending on order volume and material form. The supplier should state the recommended storage temperature, protection from direct sunlight, shelf-life guidance, and whether warming is required before transfer. Storage conditions can affect viscosity, appearance, and ease of use, so logistics planning is part of technical purchasing rather than a separate issue.

Safety and Handling Information

The exact hazard classification for CAS 9002-92-0 depends on the supplied grade, concentration, impurities, and applicable regulations. I therefore advise buyers to obtain the current SDS for the specific product before handling, repacking, transporting, or incorporating it into a formulation. A generic CAS-number search should not replace the supplier’s product-specific safety documentation.

Basic Workplace Precautions

Workers should avoid unnecessary contact with the eyes and skin and should prevent mist, spray, or heated vapors from accumulating in the work area. Suitable chemical-resistant gloves, protective clothing, and eye protection should be selected according to the SDS and the operating conditions. Good ventilation, clean transfer equipment, and clearly labeled containers are appropriate controls for routine handling.

If a spill occurs, the area should be isolated according to the site procedure, ignition and slip hazards should be assessed, and the material should be prevented from entering drains or surface water unless local procedures specifically permit it. Cleanup methods should follow the SDS and facility waste rules. First-aid measures, fire-fighting guidance, and transport classification should always be taken from the current product documentation rather than assumed from the CAS number.

How to Select the Right Supplier and Grade

For B2B sourcing, I recommend beginning with the application target instead of choosing solely by price. Define the required function, operating temperature, water phase, expected dosage, foam tolerance, packaging, annual volume, and regulatory market. Then compare suppliers using the same technical questions so that differences in active content and grade are not hidden inside the quotation.

1. Confirm the product identity and the exact commercial name associated with CAS 9002-92-0.
2. Request the TDS, SDS, certificate of analysis format, and available batch information.
3. Compare EO level, active content, cloud point, pH conditions, viscosity, and appearance.
4. Test a representative sample in the intended formulation and record dosage and process conditions.
5. Review packaging, MOQ, lead time, storage requirements, export documents, and continuity planning.

Yuking supports this process by discussing application requirements, organizing technical documentation, coordinating samples where available, and preparing commercial quotations for routine or project-based supply. We avoid treating every CAS 9002-92-0 inquiry as the same product because the correct grade depends on the customer’s formulation and process. Buyers can improve sourcing accuracy by sending their target specification, expected order volume, destination market, and intended use at the inquiry stage.

Conclusion: Is CAS 9002-92-0 Suitable for Your Application?

CAS 9002-92-0 is generally associated with a nonionic polyoxyethylene lauryl ether surfactant used for wetting, emulsification, solubilization, and cleaning support. It can be a practical ingredient for many industrial and formulation applications, but the CAS number does not by itself confirm a single performance profile. The decisive factors are the ethoxylation level, active content, cloud point, pH, viscosity, impurity profile, and compatibility with the complete system.

My recommended next step is to prepare a short technical brief covering your application, dosage range, operating temperature, packaging preference, annual demand, and required documents. Send that information to Yuking for grade review and a supply proposal. With the correct product data, sample evaluation, and SDS-based handling plan, buyers can make a more reliable decision on CAS 9002-92-0 and reduce avoidable formulation and sourcing risk.
