NIONIC™ 25R2

NIONIC™ 25R2 Surfactant is a reverse block copolymer surfactant with a chemical structure designed to provide reduced foaming and gelling tendencies compared to non-reverse block copolymer surfactants. NIONIC™ 25R2 Surfactant can be used to reduce the surface tension of liquids, including high viscosity liquids even at very low concentrations. The unique features are extremely low toxicity, defoaming activity, wetting, cleaning, emulsification, and chemical and thermal stability.
