DeTERGE LF - 7315 is a low-foaming, modified amphoteric surfactant ideal for highly alkaline and acidic systems. It functions effectively as the primary surfactant, offering wetting and detergency in both acidic and alkaline environments. Its excellent solubility may eliminate the need for a hydrotrope. Moreover, it is biodegradable, non-phenolic, and phosphate-free.

Chemical Family: Carboxylates

Labeling Claims: Aromatic-free, Biodegradable, Non-Phenolic, Phosphate-free, Phosphonate-free

Certifications & Compliance: California Proposition 65, Clean Water Act (CWA) Certified, Comprehensive Environmental Response, Compensations & Liability Act (CERCLA), National Fire Prevention Association (NFPA), SARA 313

Applicable Processes: Metalworking Applications, Oilfield Applications, Textile Scouring
