Low foaming emulsifier with excellent oil solubility
Emulsogen™ M
Edition Date :
February 06, 2026
Emulsogen™ M is a fatty alcohol ethoxylate and used as nonionic emulsifier for metalworking fluids (emulsions, semi-synthetic), rolling emulsions and water-based fire-resistant hydraulic fluids (HFA-S).
It provides excellent emulsification properties and is highly compatible with anionic formulation components. The product has very low foaming tendency, is hard water stable and offers outstanding lime soap dispersing power, being able to disperse large quantities of calcium oleate and tallate.
Because of its good solubility in most kinds of mineral and vegetable oils, Emulsogen™ M can also be used as anti-wear additive to improve lubricity.
In North America, the product is available under the tradename Emulsogen™ M A.
