The chemical name of emulsifier FM is triethanolamine monooleate (CAS No.: 2717-15-9), an ester compound formed by the dehydration condensation of one molecule of triethanolamine and one molecule of oleic acid. Its molecular structure contains both hydrophilic hydroxyl groups (—OH) and tertiary amine groups, as well as the lipophilic long carbon chain of oleic acid (C18 unsaturated fatty acid chain). This amphiphilic structure endows it with excellent emulsifying, wetting, and dispersing capabilities.
This product belongs to the category of nonionic surfactants. It does not ionize in aqueous solutions, thus exhibiting outstanding chemical compatibility. It can be compounded with anionic, cationic, and amphoteric surfactants and maintains stable emulsifying functions under acidic, alkaline, and hard water conditions. Commercially available products are usually amber to brown viscous liquids, with the active content varying depending on the specification.
It is worth noting that triethanolamine monooleate is also industrially known as triethanolamine oleate soap, oleic acid triethanolamine salt, etc. Different names refer to the same compound. In addition to the main component triethanolamine monooleate, commercial-grade emulsifier FM may contain small amounts of unreacted triethanolamine, free oleic acid, or diester by-products, but the primary active ingredient is clearly triethanolamine monooleate.
