Eumulgin B 25 is a non-ionic emulsifier for the manufacture of O/ W emulsions
Eumulgin B 25 is a nonionic emulsifier belonging to the family of ethoxylated fatty alcohol surfactants, designed to form and stabilize oil-in-water (O/W) emulsions in cosmetic and personal care formulations.
Eumulgin B 25 is typically derived from cetyl/stearyl alcohol reacted with about 25 ethylene oxide units, giving it strong water solubility and emulsification power.

Eumulgin B 25 disperses hydrophobic materials through micelle formation, encapsulating oils/greases and suspending dirt particles to prevent redeposition during washing and processing.
Eumulgin B 25 is valued for low foaming properties, especially important in machine cleaning, CIP (clean-in-place) systems, textile jet machines, and industrial washers where excessive foam disrupts mechanical washing efficiency.
Supplied as a waxy solid or flakes, it is widely used in creams, lotions, and cleansing products to create stable textures and smooth skin feel.
Eumulgin B 25 is a polyoxyethylene fatty alcohol ether surfactant, typically synthesized via ethoxylation of C16–C18 fatty alcohols (cetyl/stearyl) with ~25 ethylene oxide (EO) units, which provides a long hydrophilic polyether chain enabling strong oil-in-water emulsifying capability.
It is classified as a high-HLB nonionic surfactant, meaning its molecular structure is dominated by hydrophilic functionality, making it especially effective in emulsifying light to medium polarity oils, esters, and silicones into stable aqueous systems.
The product is delivered as soft pellets or waxy flakes for ease of handling in both cold- and hot-process manufacturing, and it can function as a primary or co-emulsifier depending on the oil phase and viscosity target.
Eumulgin B 25 is a member of the ethoxylated fatty alcohol surfactant family engineered to provide high detergency, dispersion, and wetting efficiency through its amphiphilic architecture, where a lipophilic alkyl tail interacts with soils while the hydrophilic polyether chain ensures solubility in water.
Due to the high ethoxylation degree (~25 EO units), the molecule has a high cloud point and remains stable in alkaline, high-electrolyte, and oxidative cleaning environments, making it compatible with harsh industrial processing conditions.
Its nonionic nature allows it to be unaffected by water hardness (Ca²⁺/Mg²⁺), unlike anionic surfactants, ensuring consistent performance in hard water and metal-rich systems.
Because its nonionic structure does not dissociate in solution, it maintains performance across a wide pH range and remains compatible with anionic, cationic, amphoteric, and silicone-based cosmetic ingredients — offering broad formulation latitude.
Its long EO chains promote interfacial film formation, stabilizing emulsions against coalescence, Ostwald ripening, and thermal separation, which is valuable in leave-on skincare, dermopharmaceuticals, and high-actives cosmetic systems where emulsion integrity is critical.
