Unique Low Foaming Surfactants

DeForest Low Foaming Surfactants

The DeTERGE LF products are multifuntional, low foam surfactants based on carboxylate chemistry.  Suggested for use as the primary surfactant system in formulations containing significant levels of caustic and alkaline electrolytes. These surfactants are approximately 50% active, low foaming, and have excellent wetting properties.  They are inherently biodegradable, non-phenolic and phosphate free.

DeTERGE LF-28 and DeTERGE LF-531

DeTERGE LF-28 can be formulated into cleaners containing up to 10% active NaOH and alkaline electrolytes. At a 1% concentration in 10% caustic, DeTERGE LF-28 produces zero foam, has a surface tension of ~29 dynes/cm, and a Draves Wetting time of 20 seconds. Not recommended for use in systems containing more than 5% trisodium phosphate. For use in alkaline systems only.

DeTERGE LF-531 is a highly effective, low foaming surfactant recommended for use in formulations containing up to ~25% active NaOH and will serve as a hydrotrope for nonionics in alkaline systems. At 1% by weight in 20% caustic, this product reduces surface tension to ~28 dynes/cm and has an “instant” Draves Wetting time. For use in alkaline systems only.


An excellent choice for systems containing as much as 30-40% active NaOH. At 1% by weight in 30% active NaOH, it reduces the surface tension to ~36 dynes/cm and exhibits a Draves Wetting time of 36 seconds. It’s a highly effective hydrotrope for nonionic surfactants in high caustic systems, although not recommended for use in more than 5% sodium metasilicate or trisodium phosphate. DeTERGE LF-7315 exhibits slightly higher foam vs. the other products in this series. Also stable in acidic formulations.


A complex amphoteric surfactant for use in both alkaline and acid systems. It has good detergency and wetting properties and is suggested for use in low to moderate foaming alkaline and acid cleaners. Stable in up to 35% active KOH.


An economical, very low foaming, chlorine stable, alkoxylated carboxylate recommended for use in various applications where low foam and chlorine stability are required. Exhibits detergency and wetting along with excellent hard water stability. Product is inherently biodegradable and is recommended for use in alkaline systems only.


A fast wetting, low foam amphoteric surfactant recommended to reduce the surface tension of 50% active caustic soda or 45% active caustic potash. Produces low, quick breaking foam, provides detergency, wetting, and surface tension reduction. DeTERIC CSP-50 is recommended for highly alkaline CIP cleaners as it maintains good color stability in strong caustic formulations, is hard water stable, and inherently biodegradable.
