Does TX-10 denote one fixed chemical composition?

On this page, TX-10 / NPE-10 means Nonylphenol Ethoxylate, CAS 9016-45-9, with a nominal average of about 10 EO units. TX-10 is also used for other alkylphenol ethoxylates in other contexts, so the abbreviation alone does not establish the product identity. CAS 9016-45-9 does not fix the EO distribution, active matter, water content or cloud-point result. The agreed specification identifies the supplied grade and test conditions.

What should be checked before specifying TX-10 for a destination market?

Selection depends on the intended application, destination-market rules and customer requirements. Nonylphenol ethoxylates can be subject to authorisation requirements or use-specific restrictions. If an alcohol ethoxylate is required instead, it must be evaluated in the actual formulation; a similar EO level alone does not establish technical equivalence or suitability for the destination market.

Nonylphenol Ethoxylate (TX-10 / NPE-10) CAS 9016-45-9

Nonylphenol Ethoxylate (TX-10 / NPE-10), CAS 9016-45-9, is a nonionic surfactant with a nominal average of about 10 ethylene-oxide units. The commercial grade contains a distribution of ethoxylate chain lengths rather than one discrete molecule. It is used for emulsification, wetting, detergency, dispersion and solubilization in industrial formulations. Grade selection depends on active matter, water content, physical form and cloud-point/pH results measured under defined conditions. For a quotation, include the application, required grade or specification, quantity and destination.

Product Overview

Nonylphenol Ethoxylate (TX-10 / NPE-10), CAS 9016-45-9, is an alkylphenol ethoxylate used in industrial detergents, textile auxiliaries, metal cleaning and other emulsifying or dispersing formulations. The nominal average of about 10 EO units describes the grade; it does not define a single molecular composition or fixed active matter. The supplied grade is specified by its active matter, water content, physical form and applicable quality limits. For EU/EEA supply or use, the exact substance and intended application must be assessed under the REACH authorisation framework and applicable restrictions, together with destination-market and customer requirements.

OP-10 Octylphenol Ethoxylate and Triton X-100-Type Octylphenol Ethoxylate are related alkylphenol ethoxylates with a different hydrophobic group from NPE-10. Where an alcohol ethoxylate is required, AEO-9 / MOA-9 is a separate formulation candidate. Compare EO level, active matter and cloud-point results under the same test conditions, then evaluate wetting, emulsification and compatibility in the intended formulation. A similar EO level does not establish a one-to-one replacement.

Storage, Safety and Documentation

We can provide a Certificate of Analysis (COA), Technical Data Sheet (TDS) and Safety Data Sheet (SDS) for the quoted NPE-10 grade. Quality data cover the agreed active matter, water content and grade-specific test limits. Cloud-point and pH results include the test concentration, medium and method so that grades can be compared on the same basis. The TDS and SDS describe storage and handling conditions for the supplied form.
