Does TA-15 mean every tallow amine ethoxylate molecule contains exactly fifteen EO units?

No. TA-15 is a commercial tallow-amine ethoxylate distribution centered around fifteen EO units, and tallow feedstock itself has a fatty-chain distribution. Confirm the offered EO profile, amine value, active matter, cloud-point method, physical form, and destination-specific regulatory suitability.

Which TA-15 specification points should be fixed before comparing suppliers?

Compare equivalent mass or amine value, tertiary amine, active content, water, color, physical form, viscosity and the stated clear-point or solubility method. If the product is for agrochemical or textile use, also define the formulation test and destination-market requirements.

Tallow Amine Ethoxylate TA-15 CAS 61791-26-2

Tallow Amine Ethoxylate TA-15 is a nominal 15EO grade within the CAS No. 61791-26-2 ethoxylated tallow-amine family, associated with EC No. 500-153-8. It is an alkyl and ethoxylate distribution rather than one molecule or a 99% pure substance. Its protonation, compatibility and performance change with pH. Regulatory use must also be checked carefully: ethoxylated tallow amines are listed as unacceptable co-formulants in EU plant-protection products, subject to the applicable Annex III conditions.

CAS: 61791-26-2
Synonyms: Tallow Amine Ethoxylate TA-15, Polyoxyethylene (15) Tallow Amine, PEG-15 Tallow Amine, Ethoxylated Tallow Amine, Amines Tallow Alkyl Ethoxylated
Einecs: 500-153-8
Molecular Formula: R-N[(CH₂CH₂O)ₓH][(CH₂CH₂O)ᵧH] (tallow alkyl and EO distributions)
Grade: Specify nominal EO, total and tertiary amine values, active matter, water, color, physical form, pH or solubility test, intended use and destination; compare the current TDS and batch 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.

Identity and physicochemical profile

Item	Technical guidance
Product identity	Tallow amine ethoxylate TA-15; nominal average near 15 EO
CAS / EC	61791-26-2 / 500-153-8
Composition	Tallow alkyl and EO distributions; no single exact molecular formula or molecular-purity value
Ionic behavior	Increasing protonation under acidic conditions can increase cationic character and change compatibility
Key quality controls	Total and tertiary amine values, nominal EO, water, color, pH, physical form and supplier-defined cloud or solubility tests
Regulatory boundary	Not accepted as a co-formulant in EU plant-protection products except within the applicable unintentional-impurity conditions

Applications and grade selection

TA-15 may be evaluated for compatible industrial antistatic, textile, emulsification, wetting, metalworking or cleaning systems where the destination and use are legally permitted. It should not be marketed generically as a glyphosate adjuvant without jurisdiction-specific regulatory and product authorization review.

Check compatibility with anionic surfactants and salts across the full pH and use-dilution range.
Compare amine values, nominal EO, water and physical form before testing wetting, emulsification, antistatic or corrosion-related performance.
Document the destination country and intended use before sample approval because regulatory status can differ materially by market.

Storage and handling

Store closed in a dry, ventilated area within the supplier’s recommended temperature range and away from incompatible acids, oxidants or other materials listed in the SDS. Follow the TDS for warming and homogenization if the product’s physical form changes.

Safety, documentation and procurement

Ethoxylated amines can require significant eye, skin and environmental precautions. Use the exact SDS for PPE, spill response, transport and disposal. Include intended use, destination, nominal EO, amine limits, quantity, package and regulatory-document needs in the inquiry.

For other ethoxylated fatty amine grades, compare Fatty Amine Ethoxylate AC-1205, Ethoxylated Lauryl Amine, and Ethoxylated Oleyl Amine.
