1 of 10 products in this brand
DeTERGE LF products are low foam multifunctional surfactants that provide detergency, wetting, and hydrotroping properties all-in-one product. This allows the formulator to reduce the level of other ingredients and/or eliminate the need for a hydrotrope. They are easy-to-use and will serve as the primary surfactant in formulations containing high levels of caustic and alkaline electrolytes. DeTERGE LF-7315 is also stable in acids.

Functions: Hydrotrope, Surfactant, Surfactant (Anionic), Wetting Agent

Chemical Family: Carboxylic Acids & Derivatives
