Tergitol TMN-6 is a nonionic surfactant built from a branched, trimethyl-substituted nonanol hydrophobic tail linked to a hydrophilic chain of ethylene oxide units. That branched hydrophobic structure is what distinguishes it from straight-chain alcohol ethoxylates: it gives TMN-6 particularly effective foam control and wetting behavior, along with good biodegradability, while remaining soluble in both water and polar organic solvents. Sarchem’s material corresponds specifically to CAS 60828-78-6, the TMN-6 grade within Dow’s broader Tergitol surfactant line.
TMN-6’s foam-control and wetting properties make it useful across a range of industrial formulations, including chemical-mechanical planarization (CMP) slurries used in semiconductor manufacturing, waterborne emulsion polymer synthesis, and coatings formulation as a leveling agent. It’s also used as an agricultural adjuvant to improve spray coverage and as a general nonionic wetting agent in industrial cleaning and process chemistry applications.
*Specific GHS hazard classification data was not confirmed independently for this exact grade in the sources checked; nonionic ethoxylate surfactants of this type are typically classified as eye/skin irritants with aquatic toxicity concerns. Confirm against Sarchem’s own SDS before publishing specific hazard statements.*

No — Tergitol is a Dow Chemical trademark covering a whole family of nonionic surfactant grades (NP-series, 15-S-series, TMN-series, and more). This product (CAS 60828-78-6) is specifically the TMN-6 grade; confirm which grade you need before ordering.
Yes — it's generally described as a biodegradable nonionic surfactant, which is part of why it's favored over some older surfactant chemistries in formulations with environmental considerations.
It's built from a branched trimethylnonanol hydrophobic group linked through an ether oxygen to a chain of ethylene oxide units, giving it both water-loving and oil-loving character typical of nonionic surfactants.
Yes, for every lot (SKU S3121), confirming grade and specification before use.
