Are AEO-20 and MOA-20 universal names for one identical material?

No. They are common grade labels for high-EO C12–C14 alcohol ethoxylates, but the names do not fix carbon-cut balance, EO distribution, free alcohol, or physical-form limits. Treat the offered TDS and specification as the grade definition.

What does “20EO” mean in AEO-20?

It indicates an approximate average of 20 ethylene-oxide units on a C12–C14 alcohol distribution. The material still contains multiple alkyl and ethoxylate chain lengths, so “20EO” is a grade designation rather than one molecule with a fixed formula.

Why should cloud point or melting behavior be compared under stated methods?

These results depend on concentration, test medium, thermal history, and composition. Align the method before comparing grades, then evaluate physical form, water, emulsification, wetting, foam, and stability in the actual formulation.

AEO-20 / MOA-20 C12-14 Alcohol Ethoxylate (20EO) CAS 68439-50-9

AEO-20 / MOA-20 is a commercial high-EO grade within alcohols, C12-14, ethoxylated (CAS 68439-50-9, EC 500-213-3). Its molecules contain a C12-C14 fatty-alcohol distribution and a distribution of ethoxylate chain lengths; 20EO denotes an average grade, not a single compound with one exact formula. It is used as a nonionic oil-in-water emulsifier, solubilizer and wetting or dispersing component in detergents, textiles, coatings and other formulations. For a lower-EO, more oil-affine related grade, Laureth-4 should be evaluated against the applicable specification. Buyers should match average EO, HLB, appearance, water, cloud point or melting range, hydroxyl value and application performance, then confirm the current TDS, SDS and batch COA.

CAS: 68439-50-9
Synonyms: Alcohols, C12-14, ethoxylated; C12-14 Pareth-20; AEO-20; MOA-20; Lauryl/Myristyl Alcohol Ethoxylate 20EO
Einecs: 500-213-3
Molecular Formula: UVCB/polymeric ethoxylate distribution, approximately R-(OCH2CH2)n-OH where R is C12-C14 and n averages about 20; no single fixed molecular 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.

Parameters

Identity	Alcohols, C12-14, ethoxylated; CAS 68439-50-9; EC 500-213-3; a distribution of C12-C14 alkyl chains and ethoxylate lengths with an average near 20EO, not one fixed molecule.
Specification basis	Commercial 20EO nonionic-surfactant grade. Control by the current supplier TDS and batch COA; do not use an unsupported fixed formula or single-substance purity claim.
Key parameters	Physical form and appearance, average EO or HLB, water, pH at the stated concentration, color, cloud-point method or melting/solidification range where applicable, and hydroxyl value; confirm test methods and limits in the specification.
Application test	Validate dosage, wetting, emulsification, solubilization, dispersing, foam profile and formulation stability with the buyer’s oils, builders, electrolytes, water hardness and process temperature.

Applications

Detergent and industrial-cleaning formulations.
Textile scouring, wetting and processing systems.
Oil-in-water emulsification and solubilization in coatings or process fluids.
Dispersing and formulation aid in other compatible industrial systems.

For related C12–14 alcohol ethoxylate grades, see AEO-7 and AEO-9 / MOA-9.

Storage

Store tightly closed in the original container in a cool, dry, ventilated place, protected from moisture, contamination and excessive heat. The grade may be solid or pasty at ambient temperature; follow the supplier TDS for warming, handling and shelf life.

Safety / Regulatory

For industrial use. Read the current supplier SDS before handling; avoid eye and skin contact, use suitable gloves and eye protection, provide ventilation, prevent uncontrolled environmental release, and follow applicable transport and disposal rules.
