Does CE-10 identify a fixed molecule or a defined ten-EO coco amine grade?

CE-10 denotes a commercial coco-alkyl amine ethoxylate grade with a nominal average near ten EO units. Coco feedstock contains different alkyl-chain lengths, and the EO chain lengths also vary. CAS 61791-14-8 describes the wider ethoxylated coco-amine family, so the CAS alone does not specify ten EO units. The TDS and COA describe the supplied grade and its quality parameters.

What compatibility check is important when using CE-10 with anionic ingredients?

Coco amine ethoxylates can become more cationic as pH decreases, so compatibility cannot be inferred from the nonionic label alone. Test the actual pH range, order of addition, dilution, temperature and storage stability with the complete anionic formulation before scale-up.

Polyoxyethylene Coco Amine CE-10 CAS 61791-14-8

CE-10 (CAS 61791-14-8), also called Polyoxyethylene Coco Amine or PEG-10 Cocamine, is an ethoxylated coco alkyl amine with a nominal average near 10 EO units. It is used as a wetting, emulsifying, dispersing, antistatic and corrosion-inhibiting component in textile, cleaning, metalworking and agrochemical formulations. Nominal EO level, total and tertiary amine values, water content and physical form are key selection parameters. A Certificate of Analysis (COA), Technical Data Sheet (TDS) and Safety Data Sheet (SDS) can be provided for specification and handling review.

Identity and physicochemical profile

Item	Technical guidance
Product identity	Polyoxyethylene Coco Amine CE-10; ethoxylated coco alkyl amine with nominal average near 10 EO units
CAS	61791-14-8
Nominal structure	R-N[(CH₂CH₂O)ₓH][(CH₂CH₂O)ᵧH], with nominal x+y near 10; alkyl and EO distributions are grade-dependent
Ionic behavior	The amine becomes more protonated and cationic at lower pH; ionic behavior also depends on the ethoxylation degree and formulation
Typical quality controls	Total and tertiary amine values, nominal average EO degree, water, appearance, color, pH and physical form, with stated test methods
Identity boundary	This CAS number describes ethoxylated coco amines, not coconut-oil ester or fatty-acid ester chemistry

Quality controls and analytical reports

Total and tertiary amine values are reported separately in mg KOH/g using the stated titration procedures. Water-content results identify the Karl Fischer method, while active-matter content states its analytical and reporting basis. pH results state the test medium, concentration and temperature. We can provide applicable quality-test information; any chromatographic report used for homolog distribution or free polyethylene glycol identifies the measured fraction, method, calibration and reporting basis. Chromatographic peak-area percentages do not establish mass purity.

Applications and grade selection

CE-10 is evaluated as a wetting, emulsifying, dispersing, antistatic or corrosion-inhibiting component in textile, industrial-cleaning, metalworking and agrochemical formulations. Performance depends on pH, co-surfactants, electrolytes, temperature and nominal ethoxylation level.

Check compatibility with anionic ingredients at both concentrate and use dilution, especially under acidic conditions where the amine is protonated.
Compare amine values, nominal EO, water and physical form before testing wetting, emulsion or dispersion stability and substrate performance.
A CE-10 trade description does not establish cosmetic, biocidal, food-contact or other regulated-use suitability without the relevant grade documentation.

Storage and handling

Keep containers tightly closed in a dry, ventilated area. The TDS and SDS for the supplied grade specify storage temperature, incompatible materials and any instructions for warming, mixing or sampling when low temperature changes the physical form.

Safety, documentation and procurement

Ethoxylated amines may require protection against corrosive or irritating effects depending on composition and pH. The SDS for the supplied grade gives instructions for protective equipment, spill response, transport and disposal. For a quotation, send the grade or intended application, approximate quantity and destination.

For formulation comparison, Ethoxylated Lauryl Amine and Tallow Amine Ethoxylate TA-15 offer different alkyl-chain or ethoxylation profiles, while PEG-2 Oleamine provides a lower-EO oleyl-amine comparison. Fatty Alcohol Ethoxylate AEO-7 / MOA-7 is an option for nonionic wetting and cleaning. These products are not direct substitutes; selection depends on application pH, compatibility and required performance.
