TA-15 (CAS 61791-26-2), also known as tallow amine ethoxylate or polyoxyethylene (15) tallow amine, is an ethoxylated tallow-amine mixture with a nominal average of 15 EO units per amine molecule and a range of fatty alkyl and EO chain lengths. It is used in compatible industrial antistatic, textile, emulsification, wetting, metalworking and cleaning formulations, subject to the regulations for the destination and intended use. We can provide a Certificate of Analysis (COA), Technical Data Sheet (TDS) and Safety Data Sheet (SDS), and help select the grade based on total and tertiary amine values, nominal EO number, water content, color and physical form.

Product Description
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.
- 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.
FAQ - Technical & Supply Chain
-
Q:
Does TA-15 mean every tallow amine ethoxylate molecule contains exactly fifteen EO units?
A: 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. -
Q:
Which TA-15 specification points should be fixed before comparing suppliers?
A: 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.
