CAS 9002-92-0 generally identifies polyoxyethylene lauryl ether, also known as laureth, dodecyl alcohol ethoxylate, or polyethylene glycol lauryl ether. It is a nonionic surfactant made by adding ethylene oxide to lauryl alcohol, which contains a 12-carbon hydrophobic chain. Because this CAS number can cover a family of ethoxylated materials rather than one narrowly defined molecular structure, buyers should confirm the average ethylene oxide level, physical form, active content, and application grade before ordering.

In practical terms, I recommend treating CAS 9002-92-0 as a specification-driven raw material. Its main functions include wetting, emulsification, detergency, solubilization, and dispersion support. At Yuking, we help industrial buyers compare the required performance profile with the available grade, documentation, packaging, and delivery conditions instead of selecting only by CAS number.
This guide is intended for procurement teams, formulation chemists, distributors, and manufacturers evaluating CAS 9002-92-0 for commercial use. It is especially relevant when a buyer needs a nonionic surfactant for cleaning products, personal care formulations, textile processing, industrial emulsions, or related chemical systems. It can also help importers prepare a more complete request for quotation.
The CAS number alone is not enough for a reliable purchase decision. Different suppliers may offer products with different average ethoxylation levels, appearance, water content, active matter, and performance in a specific formulation. I therefore suggest using the CAS number as an identification starting point and using the technical data sheet and certificate of analysis for final approval.
Polyoxyethylene lauryl ether combines a water-attracting polyoxyethylene segment with a lauryl-derived hydrophobic segment. This dual structure allows the material to interact with both water and oils, which explains its use as a surfactant and formulation aid. The hydrophilic-lipophilic balance changes as the average number of ethylene oxide units changes, so two products carrying the same CAS number may not behave identically.
Commercial descriptions may use terms such as laureth, dodecyl alcohol ethoxylate, or lauryl ether ethoxylate. Product naming can also include a number indicating an approximate average ethylene oxide level, although naming conventions differ between suppliers and markets. For example, grades may be described with average ethoxylation levels such as 2, 7, 9, or 23 moles of ethylene oxide per mole of alcohol; these values must be confirmed against the supplier’s specification rather than assumed from the CAS number.
The physical appearance of CAS 9002-92-0 can vary from a liquid or paste to a waxy or solid material, depending largely on the average ethoxylation level, temperature, and composition. This variation affects pumping, storage, blending, and filling operations. I recommend asking for the appearance specification at a stated temperature, especially when the material will be shipped internationally.
| Property or document | Why it matters in procurement |
|---|---|
| Average ethylene oxide level | Influences water solubility, detergency, emulsification, and handling form |
| Active matter | Helps calculate formulation dosage and compare quotations fairly |
| Water content | May affect concentration, stability, and effective delivered quantity |
| Cloud point | Provides useful information about temperature-dependent behavior in water |
| Acid value, hydroxyl value, or color | May be relevant to quality control and finished-product appearance |
Other useful parameters may include pH of a defined aqueous solution, viscosity, pour point, solidification point, unsulfated matter, and residual reactants. Not every parameter is required for every application, and the correct test method should be agreed before qualification. I advise buyers to compare specifications using the same units and test conditions because apparently similar values can be measured differently.
CAS 9002-92-0 can contribute wetting, soil removal, and emulsification in household, institutional, and industrial cleaning systems. The suitable grade depends on the required foam profile, water hardness tolerance, temperature range, fragrance compatibility, and interaction with other surfactants. A higher or lower ethoxylation level may be preferred depending on whether the formulation prioritizes oil removal, water solubility, or emulsion stability.
Ethoxylated lauryl ethers may be considered for cleansing, solubilizing, emulsifying, or viscosity-modifying roles in certain personal care formulations. However, cosmetic suitability is not established by the CAS number alone. Buyers should request the relevant impurity profile, residual ethylene oxide information where applicable, restricted-substance statement, and regulatory documentation for the target market.
In textile and industrial formulations, the material may support wetting, scouring, emulsification, or dispersion. Performance can depend on fiber type, bath temperature, electrolyte concentration, mechanical agitation, and compatibility with dyes or auxiliaries. A small laboratory screening program is advisable before a large production conversion because nonionic surfactant behavior can change significantly in a complete formulation.
Nonionic surfactants are sometimes used as wetting or emulsifying components in agricultural and technical formulations. The buyer must verify the legal status, use restrictions, and formulation-specific requirements in the destination country. I do not recommend assuming that a general industrial grade is automatically suitable for an agricultural product.
The most important distinction is the average ethylene oxide level. Lower-ethoxylated materials may show stronger oil affinity and different water behavior, while higher-ethoxylated materials may provide greater hydrophilicity and improved water compatibility. These are general formulation tendencies, not guaranteed performance results, so testing remains necessary.

Buyers should also distinguish between liquid, paste, and solid handling grades. A liquid grade may simplify metering, whereas a solid or paste grade may be selected for concentration, storage, or a specific formulation requirement. Packaging options can include smaller technical containers, 200-kilogram drums, or bulk delivery, but the actual package, net weight, and loading method must be confirmed for each order.
First, specify whether the material is required primarily for detergency, wetting, emulsification, solubilization, or dispersion. This prevents a buyer from comparing grades only by price. I also recommend identifying the target dosage range, although the correct dosage must be established by the formulator through testing.
Prepare a purchase specification covering appearance, active matter, water content, color, viscosity, cloud point, and any application-specific limits. Request an SDS, technical data sheet, certificate of analysis, and applicable compliance statements. If the product will enter a regulated formulation, include market-specific documentation in the initial inquiry.
Test the selected grade in the actual base system, including water quality, salts, solvents, oils, polymers, preservatives, and other surfactants. Observe clarity, phase separation, viscosity, foam, wetting speed, and stability during storage. A useful screening period may include at least 24 hours for initial compatibility and longer aging when the finished product requires extended shelf life.
Before issuing a purchase order, confirm the exact product name, CAS number, average ethylene oxide level, batch consistency, package type, MOQ, lead time, and shipping conditions. Ask whether the quotation is based on net weight or active content. This is particularly important when comparing products with different water levels or concentrations.
The price of CAS 9002-92-0 can vary according to ethoxylation level, raw material costs, active content, packaging, order volume, destination, and documentation requirements. A lower unit price is not necessarily the lower formulation cost if the product has a different concentration or requires additional processing. I recommend comparing cost per kilogram of active material when the grades are not equivalent.
MOQ and lead time depend on grade availability, production scheduling, package format, and export arrangements. Common industrial packaging may include 25-kilogram units or larger drums, while bulk options require suitable storage and unloading equipment. These are examples rather than universal supply commitments, so Yuking should confirm the available package and delivery schedule against the buyer’s destination and order quantity.
At Yuking, we use these questions to structure an efficient technical and commercial discussion. We can review the intended application, compare available material options, and clarify which parameters should be included in the purchasing specification. Final suitability should remain subject to the buyer’s own formulation, safety, and regulatory approval process.
Storage conditions should follow the supplier’s SDS and product documentation. The material should generally be protected from contamination, excessive heat, freezing, and prolonged exposure to unsuitable conditions, but the exact temperature range depends on the grade and physical form. Before opening a container, the buyer should confirm whether gentle warming or homogenization is permitted for a solidified or separated product.
Personnel should use the protective equipment and handling controls specified in the SDS. In particular, industrial users should review spill response, incompatible materials, ventilation, container handling, and waste management requirements. I recommend keeping the original label and batch information available throughout storage and production use.
CAS 9002-92-0 is generally associated with polyoxyethylene lauryl ether, a nonionic surfactant used for wetting, emulsification, detergency, solubilization, and dispersion support. Its performance is strongly influenced by the average ethylene oxide level and by the complete formulation environment, so the CAS number should not be used as the only purchasing specification. The most important verification points are identity, ethoxylation level, active matter, water content, physical form, documentation, and application compatibility.
For a bulk inquiry, send the intended application, target market, required annual or monthly quantity, preferred packaging, and any existing technical specification. I can then help organize the appropriate grade discussion, sample evaluation, documentation review, and quotation request through Yuking. This process gives buyers a clearer basis for selecting CAS 9002-92-0 and reduces the risk of purchasing a technically unsuitable material.
