Are AEO-9 and MOA-9 interchangeable names for one fixed chemical composition?

Not necessarily. These market names usually indicate a fatty-alcohol ethoxylate near nine EO units, but the alcohol feedstock may be lauryl or a broader C12–C14 cut. Confirm the CAS identity, carbon-chain range, cloud-point method, hydroxyl value, and active matter.

What should a buyer specify in an RFQ for AEO-9 / MOA-9?

State the required alcohol cut or reference grade, nominal EO, active matter, hydroxyl value, water, cloud-point method, physical form, application, quantity and destination. These details distinguish commercial grades that may share the same market name.

AEO-9 / MOA-9 Fatty Alcohol Ethoxylate (About 9 EO) CAS 9002-92-0

AEO-9 / MOA-9 (CAS 9002-92-0, EC 500-002-6) is a nonionic fatty-alcohol ethoxylate grade centered on about 9 ethylene oxide units. The listed identity corresponds to polyoxyethylene lauryl ether/dodecan-1-ol ethoxylated; commercial AEO-9 names may also be used for broader C12-C14 alcohol cuts, so the actual feedstock range must be confirmed in the supplier TDS and SDS. It provides wetting, detergency, emulsification and dispersion in cleaners, textile processing and industrial formulations. AEO-20 / MOA-20 is a related higher-EO grade where a more hydrophilic nonionic component is specified. As a homolog distribution, it should be specified by hydroxyl value, water, acid value, pH, appearance, cloud point or HLB and active matter rather than a fixed formula or 99% purity.

CAS: 9002-92-0
Synonyms: AEO-9; MOA-9; Fatty alcohol ethoxylate 9EO; Polyoxyethylene (9) lauryl ether; Laureth-9; Dodecan-1-ol ethoxylated; POE(9) lauryl alcohol
Einecs: 500-002-6
Molecular Formula: General structure R-O-(C2H4O)n-H, n about 9; R is chiefly C12 for CAS 9002-92-0, while some commercial AEO-9 grades use a C12-C14 distribution; no single fixed formula.
Grade: Confirm the nominal EO or PO level, feedstock range, active matter, water, physical form and relevant analytical values against the current TDS and COA.
Package: State required quantity, physical form and destination; confirm the current bag or container, liner, net weight, temperature handling and transport requirements before quotation.

Technical Specifications

Property	Specification
Identity	Fatty-alcohol ethoxylate centered on about 9 EO; CAS 9002-92-0; EC 500-002-6. Confirm the actual alcohol cut.
Specification basis	Homolog distribution controlled by grade properties and batch COA, not a fixed formula or single-compound purity.
Key controls	Alcohol cut, hydroxyl value, water, acid value, pH, appearance, cloud point or HLB and active matter.
Application test	Validate wetting, detergency, foam, emulsification, compatibility and finished-formulation stability under actual conditions.

Applications

Hard-surface and industrial cleaning formulations. Textile wetting, scouring and processing aids. Oil-in-water emulsification and dispersion. Raw material for specialty surfactant formulations after validation.

Storage

Keep tightly closed in the original compatible container in a cool, dry, ventilated place, protected from moisture, contamination, excessive heat and incompatible materials. Gentle warming may be used only if allowed by the supplier TDS when the grade becomes pasty at low temperature. Follow the stated lot shelf-life; do not assume two years.

Safety / Regulatory

Review the current supplier SDS before handling, use suitable gloves and eye protection, control spills and follow local transport, wastewater and disposal requirements. Suitability for food, personal-care or regulated uses must not be inferred from the generic AEO-9 name; confirm the offered grade and applicable approvals. Waste classification is case-specific, not automatically hazardous.
